Description

Technical field

[0001] The present invention relates to a plug connector, in particular to a plug connector which is convenient for plugging and unplugging. [Background Technology]

[0002] Chinese utility model patent No. CN207753259U, published on December 22, 2017, discloses a cable connector comprising an insulating body, a circuit board housed within the insulating body, a cable connected to the circuit board, and a locking spring. The insulating body comprises a main body, a docking portion extending forward from the main body, and a pair of baffles located on either side of the insulating body. A limiting groove is provided between each baffle and the docking portion for guiding the plug and socket to mate.

[0003] Since the circuit board is accommodated inside the insulating body, the space of the limiting groove between the baffle and the docking portion is relatively small, and precise docking is required when mating with the socket. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is to provide a plug connector that is easy to plug and unplug.

[0005] In order to solve the above technical problems, the present invention can adopt the following technical solution: a plug connector, which is used to connect with a socket connector, the plug connector includes an insulating body and a circuit board partially accommodated in the insulating body, the insulating body includes a main body, a reinforcement part extending forward from the main body, and a baffle, the circuit board extends forward from the main body and exceeds the reinforcement part, the reinforcement part is covered on the circuit board, the width of the front end of the circuit board exposed from the main body in the horizontal direction is greater than the width of the reinforcement part, a limit groove is formed between the baffle and the circuit board, and the limit groove can guide the plug connector and the socket connector to connect.

[0006] Compared with the prior art, the advantage of the present invention is that: since the width of the front end of the circuit board's exposed main body in the horizontal direction is greater than the width of the reinforcement part, the limiting groove between the baffle and the circuit board has a larger space, and there is no need for precise docking when mating with the socket.

[0026] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. [Specific implementation method]

[0027] like Figure 1-6 As shown, a plug connector 100 in accordance with the present invention is used to lock with a socket connector. The plug connector 100 includes an insulating body 1, a circuit board 2 partially housed in the insulating body 1, an inner membrane 3 housed in the insulating body, a cable 4 electrically connected to the circuit board 2, and a locking spring 5.

[0028] The insulating body 1 includes a main body 11, a reinforcement portion 12 extending forward from the main body 11, a pair of baffles 13 located on either side of the main body 11, an opening 15 at the front end of the main body 11, and a through-hole 16 connected to the opening 15. A boss 121 is provided at the upper end of the reinforcement portion 12 for securing the locking spring 5. The baffles 13 include side baffles 131, an upper baffle 132 vertically connected to the side baffles 131, and a groove 133 located inside the baffles 13. The groove 133 guides the mating of the plug connector and the receptacle connector. The upper baffles 132 extend horizontally inward from the upper ends of the side baffles 131 and are spaced above and below the reinforcement portion 12. The front ends of the side baffles 131 and the upper baffle 132 are flush and extend forwardly beyond the reinforcement portion 12. A retaining groove 14 is formed between each baffle 13 and the circuit board 2. The limiting groove 14 includes a side limiting groove 141 and an upper limiting groove 142 connected to the side limiting groove 141. The side limiting groove 141 is arranged between the circuit board 2 and the side baffle 131, and the upper limiting groove 142 is arranged between the circuit board 2 and the upper baffle 132. The limiting groove 14 passes through the insulating body 1 in the vertical and forward directions.

[0029] The circuit board 2 is placed horizontally and is inserted and molded into the insulating body 1 through the perforation 16, with an opening 15 extending forward. The circuit board 2 has an insertion portion 21 that protrudes forward from the reinforcement portion 12. A plurality of metal sheets 211 are provided on the upper and lower surfaces of the insertion portion 21. The reinforcement portion 12 is wrapped around the circuit board 2, and the horizontal width of the insertion portion 21 is greater than the width of the reinforcement portion 12. This arrangement increases the space in the retaining groove 14 between the baffle 13 and the circuit board 2, allowing for a small angled insertion of the plug connector when mated with the receptacle connector without the need for precise docking.

[0030] The inner film 3 is U-shaped and covers the connection between the circuit board 2 and the cable 4 to secure the connection between the circuit board 2 and the cable 4 .

[0031] The front end of the cable 4 is connected to the circuit board 2 , and the rear end extends backward out of the insulating body 1 .

[0032] The locking spring 5 comprises an elastic piece 51 fixed to the boss 121 and a pressing piece 52 disposed at the rear end of the elastic piece 51. The upper surface of the elastic piece 51 is provided with a locking protrusion 511 for engaging with the locking hole of the receptacle connector. The elastic piece 51 can cause the locking protrusion 511 to elastically swing up and down. When the user manually presses the pressing piece 52, the elastic piece 51 swings downward, thereby unlocking the receptacle connector.

[0033] When the plug connector 100 is docked with the socket connector, the side walls of the socket connector enter the side limit grooves 141 and are restricted from moving left and right, and the top wall of the socket connector enters the upper limit grooves 142 and is restricted from moving up and down, so as to guide the horizontal insertion of the plug connector 100, avoid the insertion portion 21 of the circuit board 2 from crossing the conductive terminals of the socket connector, and reduce the risk of PIN collapse.

[0034] The above are only some of the preferred embodiments of the present invention. Any equivalent changes made to the technical solution of the present invention by ordinary technicians in this field after reading the specification of the present invention are covered by the claims of the present invention.
