[0002] In the design process of the automobile circuit system, the automobile wiring harness is inevitably connected to various electrical components, so connectors are used to connect the wiring harnesses and the wiring harnesses and electrical appliances. In general, the number of connectors used in a car is relatively large, and a large amount of connector disassembly and assembly will be performed during assembly and maintenance. The connector is generally composed of a socket and a connector, and the connector is inserted into the socket for connection.

[0003] In the prior art, due to the small operating space and limited field of vision, the socket and the connector are easily misaligned during connection, which may cause damage to the connector in severe cases. Utility Model Content

[0004] The utility model aims to provide an automobile wiring harness anti-misalignment connector, which solves the technical problems of misalignment between a socket and a connector when connected and difficulty in operation in a narrow space and limited field of vision.

[0018] The size of the limiting plate is larger than the inner diameter of the iron half ring.

[0019] As a further optimization scheme, in order to ensure that one end of the strip slider is adsorbed and fixed when passing through the iron half ring, thereby preventing the strip slider from falling off, a magnetic block is embedded in the outer wall of one end of the strip slider close to the anti-mistake connection groove, and the magnetic block is used in conjunction with the iron half ring.

[0020] As a further optimization scheme, in order to shield the end of the sliding anti-error connection component, so that the position of the strip slider in the sliding anti-error connection component is limited, it is convenient for the strip slider to be inserted into the anti-error connection groove for guidance, and the outer wall edge of the plug-in component is equipped with a rotating baffle corresponding to the end of the sliding anti-error connection component;

[0021] After the movable part of the rotating baffle rotates to the outside of the outer wall of the connector, it blocks the end portion corresponding to the sliding anti-mistake connection component.

[0022] As a further optimization scheme, in order to facilitate the adjustment of the position of the baffle body, the end of the sliding anti-error connection assembly is shielded when necessary. The rotating baffle includes:

[0036] The edges of the clamping block on both sides along the connection direction between the plug socket and the plug connector are provided with slopes.

[0037] As a further optimization solution, in order to enhance the mechanical strength of the connection between the elastic clamping plate and the outer wall of the connector, reinforcing ribs are evenly and fixedly connected at the connection between the elastic clamping plate and the outer wall of the connector.

[0038] The utility model provides an automobile wiring harness error-proofing connector through improvement, which has the following improvements and advantages compared with the prior art:

[0039] Before the connector is inserted into the socket, it is first guided by the sliding anti-error connection component. The connector is accurately inserted into the socket through the guidance of the sliding anti-error connection component, avoiding misalignment when the socket and the connector are connected. When the sliding anti-error connection component is used, the strip slider slides and extends a certain distance to extend the guide length, which is convenient for the strip slider to align with the anti-error connection groove, and is convenient for use in an environment with a small operating space and limited field of vision.

[0052] A plug connector 2, the end of which is plugged into the plug socket 1;

[0053] There are two sliding anti-error connection components 3, and the sliding anti-error connection components 3 on both sides are guided symmetrically, so that the plug-in 2 can be accurately inserted into the plug socket 1 through the guidance of the sliding anti-error connection components 3;

[0054] Two sliding anti-error connection components 3 are symmetrically assembled on the outer walls of the socket 1 and the connector 2;

[0055] The movable part of the sliding anti-error connection component 3 slides along the connection direction of the socket 1 and the connector 2; when the sliding anti-error connection component 3 is in use, the strip slider 32 slides and extends a certain distance, extending the guide length, making it easier for the strip slider 32 to align with the anti-error connection groove 33, making it convenient to use in an environment with a small operating space and limited field of vision.

[0056] In some embodiments, in order to prevent misalignment of the connector 1 and the connector 2 through the sliding guidance of the strip slider 32 and the anti-misalignment connection groove 33, the sliding anti-misalignment connection assembly 3 includes:

[0057] An iron half ring 31, which is fixedly connected to the outer wall of the connector 2;

[0062] In some embodiments, in order to ensure that the bar slider 32 is provided with a limit plate 34, one end is stuck when passing through the iron half ring 31, so as to prevent the bar slider 32 from falling off, the end of the bar slider 32 away from the anti-misalignment connection groove 33 is fixedly assembled with the limit plate 34, and the limit plate 34 is slidably fitted with the outer wall of the connector 2;

[0063] The size of the limiting plate 34 is larger than the inner diameter of the iron half ring 31 .

[0064] In some embodiments, in order to ensure that one end of the strip slider 32 is adsorbed and fixed when passing through the iron half ring 31, thereby preventing the strip slider 32 from falling off, the outer wall of one end of the strip slider 32 close to the anti-mistake connection groove 33 is embedded with a magnet 35, and the magnet 35 is used in conjunction with the iron half ring 31.
