Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a wiring harness connector that is easy to connect. Background Art

[0002] With the development of vehicle electronic technology, vehicles are becoming more electronic and automated, and related electronic control systems are becoming increasingly complex. Therefore, the vehicle body contains many connectors, which connect the relay to the power supply through the wiring harness connector to achieve the transmission of electronic signals. Vehicle wiring harness connectors are widely used in the automotive industry, and their role in the automotive electrical system is crucial. They provide stable and reliable electrical connections, so that the vehicle electrical system can work normally, ensuring the safety and reliability of the vehicle.

[0003] Reference may be made to an existing document for a wiring harness connector that is easy to disassemble and assemble (CN219086347U). The reference document sets a clamping block and a return spring, and the return spring is deformed and the force of the deformation is applied to fix the clamping block. The clamping block cooperates with the return spring to form an extrusion positioning structure, which improves the stability of the wiring harness connection. By setting a synchronous disassembly and assembly mechanism, the positions of the two clamping blocks can be adjusted synchronously, which facilitates the disassembly and assembly of the wiring harness and reduces the damage to the wiring harness plug. However, due to the complexity of the vehicle working environment, moisture, dust and other contaminants are easily introduced into the vehicle wiring harness connection, causing electrical system failures. Moreover, the multiple groups of configurations of the disassembly and assembly structure of the reference document are completely adjusted by synchronous reverse rotation of two racks. The design of the multiple groups of accessories does not fully consider the structural deformation and displacement under the action of external force, resulting in insufficient stability of the entire structure, and the connection between the accessories is not firm and is prone to loosening, affecting work efficiency. Therefore, a wiring harness connector with good sealing performance and strong stability is required. Utility Model Content

[0004] The utility model aims to provide a wiring harness connector which is easy to connect, so as to solve the problems of the existing connector in the use process proposed in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A wiring harness connector that is easy to connect, comprising a connector body and a rotating block, wherein a connecting groove is provided at one end of the connector body, a protective shell is provided on the outer side of the front end of the connector body, and a clamping block is fixedly connected to one end of the rotating block; a waterproof ring is provided on the outer side of the front end of the connector body; a waterproof cover is provided on the inner side of the protective shell; and a rotating column is fixedly provided on the outer side of the rotating block.

[0007] Preferably, the connecting groove also includes: a snap-on chassis, which are installed at the bottom of both sides of the connecting groove, and the snap-on chassis is fan-shaped; circular grooves, which are arranged above and below both sides of the connecting groove, and the circular grooves pass through the snap-on chassis. There are four groups of circular grooves, and the rotating column is movably arranged in the middle of two relatively groups of circular grooves.

[0008] Preferably, second through holes are provided on both sides of the connector body.

[0009] Preferably, the protective shell, the rotating block and the clamping block are each provided in two groups.

[0010] Preferably, a first through hole for fixing the position of the rotating block is provided on one side of the protective shell.

[0011] Preferably, the protective shell further comprises: a magnetic body, which is arranged at the connection between the two protective shells.

[0012] Preferably, an extension portion capable of accommodating a wiring harness is fixedly connected to the rear end of the connector body.

[0013] The embodiments of the utility model provide a wiring harness connector that is easy to connect and has the following beneficial effects: the protective shell connected by the magnetic body and the waterproof cover inside the protective shell are in contact with the waterproof ring of the connector body, and a sealing structure is formed at the connection between the connector body and the wiring harness, reducing the possibility of water, dust and other debris entering. The rotating block and the clamping block with adjustable position and the protective shell that fixes the position of the rotating block facilitate the disassembly and use of the wiring harness and reduce damage to the wiring harness plug. The integrated setting of the rotating block and the clamping block improves the stability of the device.

[0014] 1. By setting a protective shell and a rotatable clamping block, the position of the clamping block is adjusted by rotating and the position of the rotating block is fixed by the first through hole on the protective shell, so that the disassembly and assembly of the wiring harness is convenient and the damage of the wiring harness plug is reduced. The integrated setting of the clamping block, the rotating column and the rotating block is more firm and stable, making it more convenient to disassemble and assemble the wiring harness when the connector is connected, and reducing the looseness of the connection of the wiring harness connector body accessories or the structural deformation and displacement.

[0015] 2. By setting a waterproof ring and a waterproof cover, the protective shell protects the connector body through the magnetic body at the connection. At the same time, the waterproof cover inside the protective shell contacts the waterproof ring of the connector body, so that a sealing structure is formed at the connection between the connector body and the wiring harness, which improves the sealing performance of the device and reduces the possibility of moisture, dust and other contaminants entering the wiring harness connection.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] Example: Figure 1 As shown, a wiring harness connector that is easy to connect includes a connecting groove 13 in the connector body 1 for placing the wiring harness, an extension portion at the rear end of the connector body 1 can accommodate the wiring harness, and two sets of protective shells 2 on the outside of the connector body 1 just cover the outside of one end of the connector body 1. The protective shells 2 also limit the position of the rotating block 3, thereby ensuring the stability of the wiring harness connector device.

[0024] like Figure 2 As shown, the waterproof ring 4 at the front end of the connector body 1 can surround the wiring harness, and the second through holes 8 on both sides of the connector body 1 facilitate the movement of the rotating block 3. The rotating block 3 rotates within the range of the second through hole 8 to drive the clamping block 11 fixed at one end to move in the connecting groove 13. The rotating block 3 and the clamping block 11 jointly control the connection and separation of the connector of the wiring harness.

[0025] like Figure 3 Figure 4As shown, the clamping block 11, the rotating block 3 and the rotating column 10 are of integrated design. The circular grooves 9 on both sides of the connector body 1 are used to place the rotating column 10. The rotating block 3 can drive the clamping block 11 to rotate in the circular groove 9 along the lower end of the rotating column 10, so as to adjust the position of the clamping block 11. The clamping chassis 12 at the bottom of both sides of the connector body 1 limit the position of the clamping block 11, reduce the position displacement of the clamping block 11 affected by external force, and increase the stability of the device. When the clamping block 11 rotates to the front end of the connecting groove 13 with the rotating block 3, the wiring harness can be placed into the connecting groove 13, and then the clamping block 11 is rotated to the middle position to clamp the wiring harness connector. When the clamping block 11 is rotated to the rear end of the connecting groove 13, the wiring harness can be freed from the restriction of the clamping block 11 and leave the connecting groove 13.

[0026] like Figure 5 As shown, the magnetic body 6 at the connection of the protective shell 2 can connect the two protective shells 2 together by adsorption force, and the two protective shells 2 can surround the outer side of the front end of the connector body 1 to play a protective role. At the same time, the waterproof cover 5 on the inner side of the front end of the protective shell 2 can contact the waterproof ring 4 at the front end of the connector body 1 to form a sealing structure, which improves the sealing of the device and reduces the entry of water, dust and other contaminants in the air at the connection between the connector body 1 and the wiring harness. The rotating block 3 can pass through the first through hole 7 in the middle of the two sides of the protective shell 2. The first through hole 7 is convenient for fixing the position of the rotating block 3 to maintain the stability of the wiring harness connection.

[0027] Working principle: the rotating block 3 can drive the clamping block 11 to rotate along the lower end of the rotating column 10 in the circular groove 9. When the clamping block 11 rotates to the front end of the connecting groove 13 with the rotating block 3, the wiring harness can be placed into the connecting groove 13, and then the clamping block 11 is rotated to the middle position. The two protective shells 2 can surround the outer side of the front end of the connector body 1 through the magnetic body 6 at the connection. The first through hole 7 in the middle of the two sides of the protective shell 2 fixes the position of the rotating block 3, which can clamp the wiring harness connector. The waterproof cover 5 on the inner side of the front end of the protective shell 2 can contact the waterproof ring 4 at the front end of the connector body 1 to form a sealing structure, which improves the sealing of the device and reduces the entry of water, dust and other contaminants in the air at the connection between the connector body 1 and the wiring harness. When the wiring harness needs to be disassembled, the protective shell 2 is detached, and the clamping block 11 is rotated to the rear end of the connecting groove 13, and the wiring harness can be freed from the restriction of the clamping block 11 and leave the connecting groove 13.
