Description

Technical Field

[0001] This application relates to a socket connector. Background Technology

[0002] Traditional USB Type-C connectors typically consist of an insulating body, multiple conductive terminals fixed within the insulating body, and a metal shell surrounding the insulating body. The conventional metal shell is usually formed by stamping and bending metal sheets to create a cylindrical shape with open ends. This leaves seams in the metal shell, which are typically secured using dovetail joints to prevent cracking under stress. Furthermore, in existing technologies, the bonding and securing force between the metal shell and the insulating body is usually achieved by a locking tab formed by an inward tearing and stamping process on the metal shell, which corresponds to a recessed groove on the insulating body to form a stop lock. This ensures the metal shell and insulating body are assembled and secured in the front-to-back direction (the insertion / removal direction of the plug connector).

[0003] However, with the iterative development of products, the existing structures in the above technologies can no longer meet the product design requirements. Therefore, it is necessary to design a new socket connector to solve the above technical problems. Summary of the Invention

[0012] Furthermore, the receiving groove extends through the base in the front-rear direction, and the front edge of the first connecting part and the second connecting part is flush with or extends forward beyond the front edge of the base.

[0013] Furthermore, at least a portion of the rear end edges of the left and right side plates abut rearward against corresponding positions of the front end face of the base; The lower surface of the base is recessed inward to form a recessed portion, and at least a portion of the rear ends of the first base plate and the second base plate are attached to the inner bottom surface of the recessed portion. The first reinforcing part is correspondingly connected to the first bottom plate that fits onto the inner bottom surface of the recessed part; The second reinforcing part is connected to the second base plate that fits onto the inner bottom surface of the recessed part.

Figures 1 to 9 As shown, a socket connector disclosed in this application includes: an insulating body 1, a plurality of terminal pieces 2 fixed within the insulating body 1, and a metal housing 3. The insulating body 1 has a base 11 and a tongue 12 extending forward from the base 11. Specifically, the tongue 12 extends forward from the middle of the front end face of the base 11.

[0030] Each terminal piece 2 includes a fixing section 21, a contact section 22 extending from one end of the fixing section 21, and a mating section 23 extending from the other end of the fixing section 21. The fixing section 21 is embedded and fixed within the insulating body 1, and the mating section 23 protrudes rearward from the base 11. At least a portion of half of the contact sections 22 is exposed on the upper surface of the tongue 12 and arranged in a row along the left-right direction; at least a portion of the other half of the contact sections 22 is exposed on the lower surface of the tongue 12 and arranged in another row along the left-right direction. The arrangement of the contact sections 22 of the terminal pieces 2 in the socket connector of this application conforms to the association standard for USB Type C socket connectors. Of course, the illustrated embodiment shows a non-full-pin terminal piece architecture; only eight terminals are provided in each of the upper and lower rows of terminal pieces 2. Of course, in other embodiments, a full-pin architecture of twenty-four pins can also be used.

[0031] Please refer to the attached reference manual. Figures 1 to 9 As shown in this application, the metal outer shell 3 is made of metal sheet by stamping and bending. Specifically, the metal outer shell 3 is at least partially fitted and fixed to the outer periphery of the base 11 and surrounds the tongue 12. The metal outer shell 3 includes a top plate 31, a left side plate 32 and a right side plate 33 formed by bending and extending the sides of the top plate 31, and a first bottom plate 34 and a second bottom plate 35 formed by the edges (lower edges) of the left side plate 32 and the right side plate 33 extending towards each other. The first bottom plate 34 and the second bottom plate 35 are spliced ​​together to form a joint 36 and are disposed opposite to the top plate 31. In a preferred embodiment, the first bottom plate 34 and the second bottom plate 35 are spliced ​​together by a dovetail structure to prevent cracking at the joint 36. In a more preferred embodiment, the joint 36 between the first bottom plate 34 and the second bottom plate 35 is further fixed by welding to further prevent cracking at the joint 36.

[0032] The metal casing 3 and the insulating body 1 together define an insertion / removal space 10 that opens to one end. The tongue 12 has a suspended plate structure. Referring to the accompanying drawings of this application, in a preferred embodiment, the first base plate 34 is bent upwards at its rear end position near the second base plate 35 in the left-right direction to form a first connecting portion 340. The second base plate 35 is bent upwards at its rear end position near the first base plate 34 in the left-right direction to form a second connecting portion 350. The rear end edge of the first connecting portion 340 is further bent and extended towards the second base plate 35 in the left-right direction to form a first reinforcing portion 341. The rear end edge of the second connecting portion 350 is further bent and extended towards the first base plate 34 in the left-right direction to form a second reinforcing portion 351. The first reinforcing portion 341 extends in both the up-down and left-right directions, and the second reinforcing portion 351 extends in both the up-down and left-right directions. The base 11 has a receiving groove 112 formed at the position corresponding to the first connecting part 340 and the second connecting part 350, and the first connecting part 340 and the second connecting part 350 are respectively received in the receiving groove 112.

[0033] In one embodiment, the first reinforcing part 341 and the second reinforcing part 351 are both attached to the rear end face of the base 11, and the first reinforcing part 341 and the second reinforcing part 351 are spliced ​​together in the left-right direction to form a joint 37. At the joint 37, the first reinforcing part 341 and the second reinforcing part 351 can be fixed by a dovetail structure, and can also be fixed by welding at the joint 37. The mutual fixation between the first reinforcing part 341 and the second reinforcing part 351 can prevent the first base plate 34 and the second base plate 35 from separating (cracking) from each other in the left-right direction, improve the overall structural strength of the metal shell 3, and also improve the holding effect between the metal shell 3 and the insulating body 1.

[0034] In another embodiment, the first reinforcing part 341 is attached to the rear end face of the base 11, and the second reinforcing part 351 is stacked and attached to the rear surface of the first reinforcing part 341. The first reinforcing part 341 and the second reinforcing part 351 can be fixed together by snap-fit ​​(for example, a protruding protrusion (not shown) is formed on one of the first reinforcing part 341 and the second reinforcing part 351, while a groove / through hole (not shown) is formed on the other, and the two are locked together by snap-fit). Of course, the first reinforcing part 341 and the second reinforcing part 351 can also be fixed together by welding.

[0035] In a preferred embodiment, the rear end face of the base 11 is recessed inward (i.e., forward) with a clearance groove 111, and the first reinforcing part 341 and the second reinforcing part 351 are correspondingly accommodated within the clearance groove 111. In a preferred embodiment, the rear surfaces of the first reinforcing part 341 and the second reinforcing part 351 are flush with the rear end face 110 of the base 11. When the first reinforcing part 341 and the second reinforcing part 351 are stacked in the front-rear direction, the rear surface of the rearmost of the first reinforcing part 341 and the second reinforcing part 351 is flush with the rear end face 110 of the base 11. Of course, if the width of the base 11 of the insulating body 1 in the front-rear direction is insufficient, the clearance groove 111 may not be provided.

[0036] Please refer to the reference. Figures 4 to 9 As shown, the receiving groove 112 extends through the base 11 in the front-rear direction. The front edge of the first connecting portion 340 and the second connecting portion 350 is flush with or extends forward beyond the front edge of the base 11. When the plug connector mates with the socket connector of this application, the plug connector inserted into the insertion / removal space 10 can be stopped by the front edge of the first connecting portion 340 and the second connecting portion 350, thus preventing the plug connector from damaging the insulating body 1 of the socket connector, especially the front edge of the base 11.

[0037] In this application, the arrangement of the first reinforcing part 341 and the second reinforcing part 351 can also prevent the metal shell 3 from detaching forward from the insulating body 1.

[0038] In other embodiments, the first connecting portion 340 and the second connecting portion 350 may be omitted, and the receiving groove 112 structure may be eliminated simultaneously. The first reinforcing portion 341 and the second reinforcing portion 351 are designed as follows: the rear end edge of the first base plate 34 is bent and extended along the vertical direction towards the side near the top plate 31 to form the first reinforcing portion (not shown, but the structure can be similar to the first reinforcing portion 341 structure described above). The rear end edge of the second base plate 35 is bent and extended along the vertical direction towards the side near the top plate 31 to form the second reinforcing portion (not shown, but the structure can be similar to the second reinforcing portion 351 structure described above). That is, the first reinforcing portion and the second reinforcing portion are directly formed by bending and extending the rear end edges of the corresponding first base plate 34 and second base plate 35. Of course, the first reinforcing portion and the second reinforcing portion can be fixed using the mating fixing method described above.

[0039] Furthermore, please refer to the references. Figures 2 to 9 As shown, at least a portion of the rear end edges of the left side plate 32 and the right side plate 33 abut rearward against corresponding positions of the front end face of the base 11, as detailed in the attached diagram. Figure 2 and Figure 6As shown, the rearward edges of the left side plate 32 and right side plate 33, corresponding to positions near the first base plate 34 and the second base plate 35, abut rearwardly against corresponding positions on the front end face of the base 11. The lower surface of the base 11 is recessed downward to form a recess 113, and at least a portion of the rear ends of the first base plate 34 and the second base plate 35 are attached to the inner bottom surface of the recess 113. The first reinforcing part 341 is correspondingly connected to the first base plate 34, which is attached to the inner bottom surface of the recess 113. The second reinforcing part 351 is correspondingly connected to the second base plate 35, which is attached to the inner bottom surface of the recess 113.

[0040] In the socket connector of this application, the metal shell 3 and the insulating body 1 are stably bonded and the metal shell 3 is not prone to cracking, especially at the joint 36.

[0041] The electrical connector described in this application can be installed in electronic devices for signal transmission, including functions such as charging, such as mobile phones, tablets, computers, printers, projectors, cameras, air conditioners, televisions, monitoring equipment, etc.
