Description

[Technical Field]

[0001] This invention relates to a plug connector, and more particularly to a plug connector with reduced connector height. [Background Technology]

[0002] Chinese Utility Model Patent No. CN207398496 U, published on May 22, 2018, discloses a connector including an insulating body, a PCB board fixed on the insulating body, and a cable with one end electrically connected to the PCB board and extending rearward out of the insulating body.

[0003] However, the connector is large in size and takes up a lot of space, which is not conducive to the miniaturization of connectors. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide a plug connector that reduces the height of the connector.

[0005] To solve the above-mentioned technical problems, the present invention can adopt the following technical solution: a plug connector for mating with a socket connector, the plug connector including an insulating body and a locking spring located at the upper end of the insulating body, the socket connector having a groove on its upper surface, the insulating body including a main body and a mating part extending forward from the main body, the bottom of the mating part protruding downward to form a recessed part, the recessed part being located above the groove but not entering the groove.

[0006] Compared with the prior art, the advantages of the present invention are: through the above design, not only can the height of the plug connector be reduced, but also the stability of the plug connector structure can be enhanced by setting a recessed part at the bottom of the mating part.

Detailed Implementation Methods

[0030] like Figure 1-6 As shown, a plug connector 100 conforming to the present invention is used for locking with a socket connector 200. The plug connector 100 includes an insulating body 1, a circuit board 2 housed within the insulating body 1, a cable 3 electrically connected to the circuit board 2, an inner mold 4 covering the connection between the circuit board 2 and the cable 3, and a locking spring 5 located on the insulating body 1. The upper surface of the socket connector 200 is provided with a groove 201.

[0031] The insulating body 1 includes a main body 11, a mating portion 12 protruding forward from the main body 11, a pair of side baffles 13 located on the left and right sides of the main body 11, a square hole 14 located on the upper surface of the main body 11, an opening 15 located at the front end of the main body 11, and a channel 16 communicating with the opening 15. The upper surface of the mating portion 12 is provided with a recess 121 extending backward from the front end, a protrusion 122 for fixing the locking spring 4, and bosses 123 located on both sides of the locking spring 4. The front end of the recess 121 does not penetrate the upper surface of the mating portion 12. The lower surface of the mating portion 12 is provided with a downwardly protruding recess 124, which increases the thickness of the front surface of the mating portion 12 and enhances the stability of the plug connector structure. The recess 124 is located above the groove 201 but does not enter the groove 201. A second limiting groove 131 is formed between the side baffle 13 and the circuit board 2. The second limiting groove 131 provides left and right limiting to guide the plug connector 100 to mate with the socket connector 200.

[0032] The circuit board 2 includes an insertion portion 21 extending from the opening 15, and the upper and lower surfaces of the insertion portion 21 are provided with a plurality of metal pieces 211. The mating portion 12 is located on the upper side of the insertion portion 21, and a first limiting groove 125 is formed between the mating portion 12 and the insertion portion 21. The first limiting groove 125 can provide upper and lower limits when the plug connector 100 and the socket connector 200 are mated, preventing the circuit board 2 from being inserted at an angle and preventing pin breakage (the terminal is deformed and cannot be restored to its original shape).

[0033] The front ends of the cable 3 are respectively soldered to the upper and lower surfaces of the circuit board, and the rear end extends backward to form an insulating body 1.

[0034] The upper surface of the inner mold 4 is provided with a downwardly recessed middle part 41 and protrusions 42 located on both sides of the middle part. The protrusions 42 are provided with ribs 421 that mate with the corresponding square holes 14. The inner mold 4 passes through the channel 16 and enters the insulating body 1, so that the ribs 421 are engaged with the square holes 14 to prevent the inner mold 4 from exiting the insulating body 1.

[0035] The locking spring 5 is installed in the recess 121 and includes a fixing part 51 that is snapped into place by the protrusion 122, an elastic part 52 connected to the fixing part 51, and a pressing part 53 located at the rear end of the elastic part 52. The upper surface of the elastic part 52 is provided with a locking protrusion 521 for engaging with the locking hole 202 of the socket connector 200. The elastic part 52 can drive the locking protrusion 521 to swing up and down elastically. Because the recess 121 is recessed inward, there is sufficient space between the pressing part 53 and the upper surface of the recess 121 for the user to press the locking spring 5 to unlock, thereby further reducing the overall height of the cable connector 100 and achieving connector miniaturization.

[0036] The above are only some preferred embodiments of the present invention. Any equivalent changes to the technical solutions of the present invention made by those skilled in the art after reading the present invention specification are covered by the claims of the present invention.
