DETAILED DESCRIPTION OF THE INVENTION

An engagement structure in embodiments of the present disclosure is described below with reference to accompanying drawings.

The above and other technical features and advantages of the disclosure are herein illustrated with preferred embodiments, depicted with drawings, and described below. It is worth noting that directional expressions mentioned in the embodiments below, such as “upper”, “lower”, “left”, “right”, “front” or “rear”, refer to the directions depicted in accompanying drawings. Thus, the directional expressions are illustrative rather than restrictive of the disclosure. Furthermore, in the embodiments below, like components are denoted by like reference numerals.

Referring to FIG. 1 through FIG. 4, the disclosure provides an engagement structure 1 and an engagement method for the same. The engagement structure 1 comprises a body portion 11 and at least one connecting portion 12.

The connecting portion 12 is movably disposed at the body portion 11. A limiting portion 121 is disposed on at least one side of the connecting portion 12. The connecting portion 12 engages with an engaged object 10 to confine the engaged object 10 to a confinement range of the limiting portion 121.

The process of fixing the engaged object 10 in place entails fitting the body portion 11 to an object 20, fitting one end of the engaged object 10 to a connector 30, and moving the connecting portion 12 to fit the other end of the engaged object 10 to the limiting portion 121 of the connecting portion 12 such that the connecting portion 12 confines the engaged object 10 to a confinement range of the limiting portion 121 to enable the connecting portion 12 to snap-engage with the two sides, upper side and lower side of the engaged object 10, so as for the two sides, upper side and lower side of the limiting portion 121 to be confined to the engaged object 10. The process of removing the engaged object 10 involves moving the connecting portion 12 to separate the other end of the engaged object 10 from the limiting portion 121 and thus cause the removal of the engaged object 10 from the connecting portion 12, allowing at least two objects to be coupled together and separated repeatedly and quickly.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the body portion 11 is fitted to the object 20 by engagement, riveting, expanded connection, resilient engagement, soldering, fastening, penetrated connection, magnetic attraction or adhesion, or the body portion 11 and the object 20 are integrally formed. Therefore, the body portion 11 is firmly fitted to the object 20 as needed.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the engaged object 10 is a board card, M.2 card, E1.S card, E3.S card, NIC card, RAM, hard disk drive, storage, IC, chip, heat-dissipating object, cooling fin, CPU, GPU, heat sink, PCB or connector, whereas the object 20 is a circuit board, connector, metallic board, server, chamber, cabinet, storage, computer or plastic board, with the connector 30 being an electrical connector of any type. Therefore, the present disclosure meets requirements for practical application.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, rotation-proof portions 13, 201 are disposed between the body portion 11 and the object 20. Therefore, after the body portion 11 has been fitted to the object 20, the rotation-proof portions 13, 201 are effective in preventing rotation such that the body portion 11 is firmly fitted to the object 20 to facilitate the operation of the connecting portion 12.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, a resilient component 14 is disposed between the body portion 11 and the connecting portion 12 and adapted to allow the connecting portion 12 to resiliently engage with the engaged object 10. Upon the movement of the connecting portion 12, the connecting portion 12 compresses the resilient component 14. Thus, after the other end of the engaged object 10 has been fitted to the limiting portion 121 of the connecting portion 12, the resilient component 14 is resiliently released to therefore push the connecting portion 12, confining the engaged object 10 to the confinement range of the limiting portion 121. The process of removing the engaged object 10 involves moving the connecting portion 12 to compress the resilient component 14 such that, upon separation of the other end of the engaged object 10 from the limiting portion 121 and thus removal of the engaged object 10 from the connecting portion 12, the resilient component 14 is resiliently released to therefore push the connecting portion 12 for the sake of reuse, allowing at least two objects to be coupled together and separated repeatedly and quickly.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the body portion 11 has a blocking portion 15, whereas the body portion 11 and the connecting portion 12 are movably fitted together by a bolt element 16 (or a fitting element). The bolt element 16 is penetratedly disposed at the blocking portion 15. A movement space 122 is disposed on each of the two sides of the connecting portion 12. When the connecting portion 12 moves, the bolt element 16 moves within the movement space 122.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the body portion 11 and the connecting portion 12 are movably fitted together by a resilient arm, or the body portion 11 and the connecting portion 12 are movably fitted together by a plastic engaging portion. Therefore, the present disclosure meets requirements for practical application.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the connecting portion 12 has a guiding portion 17, whereas the resilient component 14 is penetratedly disposed at the guiding portion 17. The two ends of the resilient component 14 abut against the blocking portion 15 and the connecting portion 12 respectively. The guiding portion 17 steadily guides the resilient component 14, allowing the connecting portion 12 to resiliently engage with the engaged object 10.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the rotation-proof portion 13 is disposed between the connecting portion 12 and the body portion 11 and adapted to function as a movement slot and prevent rotation such that the connecting portion 12 can undergo lateral movement relative to the body portion 11 but not rotation, so as to maintain the stability of the connecting portion 12 in motion.

In addition to the aforesaid embodiments, in an embodiment of the disclosure, the engaged object 10 is hot-plugged into the connector 30 and then engages with the connecting portion 12 (as shown in FIG. 4). Therefore, the present disclosure meets requirements for practical application.

Referring to FIG. 5, in addition to the aforesaid embodiments, in an embodiment of the disclosure, the body portion 11 and the connecting portion 12 are movably fitted together by an engaging portion 18. In this embodiment, the engaging portion 18 is a combination of a track 181 and a rail 182. Therefore, the connecting portion 12 moves along the engaging portion 18 relative to the body portion 11, so as to maintain the stability of the connecting portion 12 in motion.

Referring to FIG. 6, in addition to the aforesaid embodiments, in an embodiment of the disclosure, the body portion 11 has a guiding portion 17, whereas the connecting portion 12 has a blocking portion 15. The guiding portion 17 and the blocking portion 15 correspond in position to each other. The resilient component 14 is penetratedly disposed at the guiding portion 17. The two ends of the resilient component 14 abut against the blocking portion 15 and the body portion 11 respectively. The guiding portion 17 guides the resilient component 14. The guiding portion 17 steadily guides the resilient component 14 to not only allow the connecting portion 12 to resiliently engage with the engaged object 10 but also allow the lower side of the engaged object 10 to rest on the body portion 11. Therefore, the present disclosure meets requirements for practical application.

Referring to FIG. 7, in addition to the aforesaid embodiments, in an embodiment of the disclosure, the connecting portion 12 has a guiding portion 17, whereas the body portion 11 has a blocking portion 15. The guiding portion 17 and the blocking portion 15 correspond in position to each other. The resilient component 14 is penetratedly disposed at the guiding portion 17. The two ends of the resilient component 14 abut against the blocking portion 15 and the connecting portion 12 respectively. The guiding portion 17 guides the resilient component 14. The guiding portion 17 steadily guides the resilient component 14 to not only allow the connecting portion 12 to resiliently engage with the engaged object 10 but also allow the connecting portion 12 to snap-engage with the two sides, upper side and lower side of the engaged object 10 and place limitation thereon with the limiting portion 121. Therefore, the present disclosure meets requirements for practical application.

Referring to FIG. 8 and FIG. 9, in addition to the aforesaid embodiments, in an embodiment of the disclosure, the limiting portion 121 is a rectangular notch (as shown in FIG. 8) or n-shaped notch (as shown in FIG. 9). Owing to the limiting portion 121 of the connecting portion 12, the connecting portion 12 snap-engages with the two sides, upper side and lower side of the engaged object 10 and places limitation thereon with the limiting portion 121. Alternatively, the connecting portion 12 snap-engages with the two sides and upper side of the engaged object 10, and the lower side of the engaged object 10 rests on the body portion 11. Therefore, the present disclosure meets requirements for practical application.
