Description

Technical Field

[0001] This application relates to the field of electronic components technology, and in particular to a connector. Background Technology

[0002] Leakage-proof connectors are used to reliably connect electrical wires and safely transfer electrical energy from the first wire to the second wire. Leakage-proof connectors are particularly used in building automation, instrumentation, automotive, and industrial equipment.

[0003] In related technologies, adding signal terminals to leakage current protection connectors requires increasing the size of the connectors, and larger leakage current protection connectors have greater limitations in use. Summary of the Invention

[0004] In order to minimize the size of the connector after adding signal terminals, this application provides a connector.

[0005] A connector includes a male plug and a female plug, the female plug being inserted into the male plug. The male plug is provided with a plurality of first connecting pieces, and the female plug is provided with a plurality of second connecting pieces corresponding to the positions of the first connecting pieces. After insertion, the plurality of first connecting pieces are all located above the corresponding second connecting pieces. The second connecting pieces are bent toward the first connecting pieces to form a bent portion, and the bent portion abuts against the lower part of the first connecting piece.

[0006] By adopting the above technical solution, the input terminal of the external power supply is connected to the female plug, and the second connecting piece on the female plug is used to transmit signals or energy. Because the second connecting piece is pressed against the first connecting piece, the male plug can transmit the transmitted signals or energy to the output terminal of the external power supply. This adds signal transmission function to the connector while reducing the overall size of the connector.

[0007] Secondly, the stability of the connector can be further increased by the first and second connecting pieces, which can minimize the vibration of the connector after connection, thus preventing the connector from disconnecting from the external power supply.

[0008] Optionally, the male plug has a insertion groove, and the female plug has an insertion block. The insertion block is inserted into the insertion groove. The male plug has a plurality of first connecting holes along the insertion direction. The plurality of first connecting holes extend toward the insertion groove and form a groove. The first connecting piece passes through the first connecting hole and abuts against the side wall of the groove near the insertion block. The first connecting piece abuts against the outer wall of the insertion block.

[0009] By adopting the above technical solution, the female plug is connected to the male plug through the insertion slot of the insertion block, and after insertion, the first connecting piece is located on the outer wall of the insertion block.

[0010] Optionally, a first limiting groove is provided in the first connecting hole to limit the extension length of the first connecting piece, and the inner wall of the first limiting groove abuts against the first connecting hole.

[0011] By adopting the above technical solution, the first connecting piece is prevented from extending excessively into the groove, so as to avoid the insertion block from colliding with the first connecting piece during insertion.

[0012] Optionally, the female plug has several second connecting holes corresponding to the positions of the first connecting holes along the plugging direction. The extended end of the second connecting hole forms a deformation groove on the insert block for bending of the bending part. An extension hole is provided on the inner wall of the deformation groove near the plugging groove, and the second connecting piece extends into the extension hole.

[0013] By adopting the above technical solution, the bending part deforms and the extension part extends into the extension hole, which can effectively prevent the second connecting piece from being squeezed against the inner wall of the deformation groove, thus avoiding damage to the second connecting piece.

[0014] Optionally, the male connector has several transmission terminals running through it, and the female connector has several connection terminals running through it, corresponding to the positions of the transmission terminals. The transmission terminals are inserted into the connection terminals.

[0015] By adopting the above technical solution, current is transmitted through the connection between the transmission terminal and the connection terminal.

[0016] Optionally, the transmission terminal includes an output portion, and the first connecting piece includes a first plug portion, both of which extend and bend towards the upper end face of the male connector.

[0017] By adopting the above technical solution, different types of external output connectors can be adapted by bending the output part and the first insertion part.

[0018] Optionally, a protective plate is provided on the upper surface of the male connector, and the output part and the first plug-in part extend through the protective plate in a direction away from the protective plate. The protective plate is located above the bend between the output part and the first plug-in part.

[0019] By adopting the above technical solution, the protective plate separates the output part and the first plug part below it from the external power supply, which can effectively prevent damage to the bending parts of the output part and the first plug part.

[0020] Optionally, the bottom of the insertion slot is provided with a fixing slot, the inner side wall of the insertion slot is provided with a foolproof block, the side of the insertion block near the insertion slot is provided with a fixing block, the side wall of the insertion block is provided with a foolproof slot, the fixing block is inserted into the fixing slot, and the foolproof block is inserted into the foolproof slot.

[0021] By adopting the above technical solution, the user can effectively avoid mis-insertion when connecting the male and female plugs.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. It can add signal transmission function to the connector while reducing the overall size of the connector;

[0024] 2. The stability of the connector can be further increased by the first and second connecting pieces, which can minimize the vibration of the connector after connection and prevent the connector from disconnecting from the external power supply. Attached Figure Description

Each of the two first connecting pieces 5 includes a first insertion part 501, a first limiting part 502, and a pressing part 503 connected in sequence.

[0034] When the first connecting piece 5 is installed on the male connector 1, the pressing part 503 of the two first connecting pieces 5 passes through the first connecting hole 7 and extends into the groove 11, and the end of the pressing part 503 abuts against the inner wall of the groove 11 on the side near the female connector 2. The side of the two first limiting parts 502 near the female connector 2 abuts against the inner wall of the corresponding first limiting groove near the female connector 2, and the two first insertion parts 501 abut against the outer wall of the male connector 1 away from the female connector 2.

[0035] refer to Figure 1 , Figure 2 The female plug 2 has two wire slots on the side opposite to the insertion block 201, which correspond to the positions of the two wire slots. Each of the two wire slots is provided with a connection terminal 4 that is plugged into the transmission terminal 3.

[0036] The connection terminal 4 includes an input section 401 and a transmission section 402. The input section 401 is inserted into a wire slot, and the transmission section 402 is disposed within the connector block. The transmission section 402 has a mounting groove with an opening facing the transmission terminal 3.

[0037] refer to Figure 1 , Figure 2 The bottom of the insertion slot 13 has a fixing slot 12, and a foolproof block 101 is fixedly connected to its inner side wall. A fixing block 202 is fixedly connected to the side of the insertion block 201 near the insertion slot 13, and a foolproof groove 14 is formed on the side wall of the insertion block 201.
