Description

Technical Field

[0001] The utility model relates to the field of connector design, in particular to a connector self-locking part. Background Art

[0002] Micro-rectangular electrical connectors have been a rapidly growing type of connector in China in recent years, boasting significant application value and development potential in aerospace and other military fields. Modern weaponry is increasingly moving toward miniaturization, lightweighting, high integration, multi-functionality, and high reliability, a trend that will only intensify in the future. To meet the evolving needs of complete machine models, the accompanying electronic components must also possess these characteristics. As fundamental electronic components, the technological level of electrical connectors directly impacts the fundamental quality of the entire machine. Consequently, the development trend of complete machines places higher demands on the supporting electrical connectors.

[0003] The prior art (announcement number: CN213936617U, announcement date: 2021.08.10) discloses an automatic locking connector, which is provided with a fastening ring that can limit the base of the socket connector to a certain extent during installation, facilitating the installation of the wire jack and locking pad on the base of the socket connector. The inside of the fastening ring can be filled with epoxy resin, which can not only effectively fix the wire jack, but also ensure that the wire crimping point is not subjected to stress during the process of plugging and unplugging the connector.

[0004] However, in the above solution, the connector will be completely locked by the locking hook after being plugged in, and there is no potting hole, which makes it difficult to pot the epoxy resin. During potting, the epoxy resin may also flow onto the copper core or pin, resulting in poor contact. Therefore, it is necessary to design a connector self-locking part to solve this technical problem. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A connector self-locking part includes a connector plug, and a plug-in portion is formed at the lower end of the connector plug; bosses are formed on both sides of the left and right sides of the connector plug, and the bosses are located on the left and right sides of the upper end of the plug-in portion, and self-locking edges are formed on the outer side of the bosses, and an elastic arm structure is formed between the self-locking edge and the bosses, and an undercut is formed on the inner side of the lower end of the self-locking edge, and a pressing block is formed on the outer side of the upper end of the self-locking edge; a plurality of jacks are formed on the connector plug, and the plurality of jacks are arranged in a matrix in the connector plug, and a conductive copper bus is installed with a gap fit in the jacks, and potting transverse grooves are formed on the front and back sides of the connector plug, and the potting transverse grooves on the front and back sides are symmetrically arranged with each other, and the inner side of the potting transverse groove leads to the jack setting.

[0007] Furthermore: an isolation edge is formed on the outer side of the conductive copper busbar, the outer edge of the isolation edge is pressed on the inner wall of the socket, and the isolation edge is located below the potting horizontal groove.

[0008] Furthermore: the lower end of the conductive copper busbar and the socket are matched with each other, and the lower end of the conductive copper busbar is formed with a plug-in end.

[0009] Furthermore: one or more bent edges are formed on the outer side of the conductive copper busbar, an electric wire is electrically connected and installed on the conductive copper busbar, and an exposed end is provided at the lower end of the electric wire. After the one or more bent edges are bent, the exposed end of the electric wire is locked on the conductive copper busbar.

[0010] Furthermore: the undercut is set lower than the connector plug, and the pressing block is set higher than the connector plug.

[0011] Furthermore: both left and right sides of the upper end of the connector plug are formed with limiting edges, the limiting edges are arranged above the bosses in a one-to-one correspondence, and the limiting edges and the self-locking edges are staggered inwards and outwards.

[0012] Furthermore: a plug-in bevel is formed at the lower end of the undercut, a first rounded corner is formed between the left and right sides of the connector plug and the boss, and a second rounded corner is formed between the boss and the self-locking edge.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. Open a potting groove on the connector plug. Since the potting groove and the jack are connected to each other, after installing the conductive copper busbar, you can directly pour epoxy resin glue into the potting groove to fill the gap between the conductive copper busbar and the jack. After the epoxy resin glue dries, it can effectively fix the conductive copper busbar.

[0015] 2. During the pouring process, the isolation edge on the outside of the conductive copper busbar can effectively block the epoxy resin glue, thereby preventing the epoxy resin glue from contacting the bottom of the conductive copper busbar, thereby avoiding the epoxy resin glue affecting the normal use of the connector.

[0028] The principle is as follows: a potting groove 9 is provided on the connector plug 1. Since the potting groove 9 and the jack 7 are interconnected, after the conductive copper bus 8 is installed, epoxy resin glue can be directly poured into the potting groove 9 to allow the epoxy resin glue to fill the gap between the conductive copper bus 8 and the jack 7. After the epoxy resin glue is dried, the conductive copper bus 8 can be effectively fixed. During the pouring process, the isolation edge 10 on the outside of the conductive copper bus 8 can effectively block the epoxy resin glue, thereby preventing the epoxy resin glue from contacting the bottom end of the conductive copper bus 8, thereby avoiding the epoxy resin glue from affecting the normal use of the connector.

[0029] Furthermore: the lower end of the conductive copper bus 8 and the socket 7 are matched with each other, and the lower end of the conductive copper bus 8 is formed with a plug end 11; the setting of the plug end 11 can facilitate the plugging and use of the connector, and a pin can be inserted into the plug end 11 to complete a stable electrical connection.

[0031] Furthermore: the undercut 5 is set lower than the connector plug 1, and the pressing block 6 is set higher than the connector plug 1; an integrated seesaw structure is formed between the boss 3 and the self-locking edge 4, and the self-locking edge 4 can also automatically recover elastically after pressing the pressing block 6, which is convenient for stable plugging of the connector.

[0032] Furthermore: the left and right sides of the upper end of the connector plug 1 are formed with limiting edges 15, and the limiting edges 15 are arranged one by one above the boss 3, and the limiting edges 15 and the self-locking edges 4 are staggered inside and outside with each other; it can play the role of pressing limit, avoiding the pressing block 6 from being pressed too far, thereby ensuring the service life of the self-locking edge 4.
