Description

Technical Field

[0001] This utility model belongs to the field of wire harness connector technology, and more specifically, it relates to a waterproof and corrosion-resistant wire harness connector. Background Technology

[0002] When connecting wire harnesses, they are usually connected through wire harness connectors. The connector mating joint is usually equipped with a rubber sealing ring to seal and waterproof the connection. The connector shell is made of corrosion-resistant material to ensure the connector is waterproof and corrosion-resistant. The connector is equipped with a locking buckle to ensure the connection of the wire harness is stable.

[0003] For example, CN213816560U discloses a wire harness connector, including: an inner frame, a wire harness terminal assembly, and a housing. The inner frame includes: a main body and a bridging member. The front end of the main body has a connector portion with a movable channel. The rear end of the main body has a positioning portion with a positioning groove communicating with the movable channel. The bridging member covers the positioning groove, with one side of the bridging member hinged to one side of the positioning portion and the other side of the bridging member snapped into the other side of the positioning portion. The wire harness terminal assembly includes: metal terminals and a wire harness. The metal terminals pass through the movable channel, and the wire harness is placed in the positioning groove and snapped between the positioning portion and the bridging member. The housing covers the connector portion, the positioning portion, and the bridging member. In this wire harness connector, the wire harness terminal assembly is first assembled and fixed on the inner frame. Under the protection of the inner frame, the wire harness terminal assembly is then encapsulated by injection molding to form a sealed housing, which not only has high sealing performance but also has low manufacturing difficulty.

[0004] Based on the above, the locking buckle is prone to loosening when it is impacted. If the wire harness connector is pulled, the wire harness connection is likely to break, affecting the stability of the wire harness connection and thus affecting the performance of the wire harness connector. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a waterproof and corrosion-resistant wire harness connector to solve the problem that the locking buckle is prone to loosening when impacted. In this case, the wire harness connector is easily pulled, causing the wire harness connection to break, affecting the stability of the wire harness connection, and thus affecting the performance of the wire harness connector.

[0006] The purpose and effect of this waterproof and corrosion-resistant wire harness connector are achieved by the following specific technical means:

[0007] A waterproof and corrosion-resistant wire harness connector includes a first connector, a second connector, a positioning locking buckle, a positioning locking block, a limiting support frame, a warning structure, a support structure, a limiting pressure plate, and an audible and visual alarm. The second connector is inserted into the right side of the first connector. The positioning locking buckle is hinged to the upper part of the first connector. The positioning locking block is fixedly connected to the upper part of the second connector. The limiting support frame is fixedly connected to the upper end face of the second connector. The warning structure is disposed above the second connector. The limiting pressure plate is slidably connected up and down to the middle of the limiting support frame. The audible and visual alarm is bolted to the upper part of the limiting pressure plate. Both the first and second connectors are made of a composite material with polytetrafluoroethylene as the matrix and dispersed nano-scale graphene sheets and silver nanoparticles. The support structure is disposed on the left side of the second connector.

[0008] Furthermore, the warning structure includes a limiting guide plate and a guide sliding block; two limiting guide plates are provided, and the two limiting guide plates are respectively fixedly connected to the left and right sides of the limiting support frame; two guide sliding blocks are provided, and the two guide sliding blocks are respectively fixedly connected to the left and right sides of the limiting clamping plate, and the two guide sliding blocks are respectively slidably connected to the two limiting guide plates.

[0009] Furthermore, the warning structure also includes a push-button switch and a clamping elastic element; the push-button switch is located on the upper part of the left guide sliding block; there are two clamping elastic elements, and the two guide sliding blocks are elastically connected to the limiting support frame through the two clamping elastic elements.

[0010] Furthermore, the support structure includes a rubber sealing ring and a limiting connecting groove; the rubber sealing ring is bonded to the left side of the second connecting seat; the limiting connecting groove is formed on the left side of the second connecting seat.

[0011] Furthermore, the support structure also includes a sliding support plate and a reset elastic element; the sliding support plate is slidably connected to the inner side of the limiting connection groove; two reset elastic elements are provided, and the sliding support plate is elastically connected to the second connecting seat through the two reset elastic elements.

[0012] Furthermore, the support structure also includes a flexible protective sleeve and a dustproof sealing bag; two flexible protective sleeves are provided, and the two flexible protective sleeves are respectively fixedly connected to the left side of the first connecting seat or the right side of the second connecting seat; two dustproof sealing bags are provided, and the two dustproof sealing bags are respectively adhered to the front and rear sides of the second connecting seat.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention effectively ensures the corrosion resistance of the wire harness connector by using special materials for the first and second connecting seats, thus improving its service life. A rubber sealing ring prevents moisture from entering the connector from the mating point, effectively avoiding short circuits and ensuring the safety of the wiring connection. A limiting clamping plate continuously presses the positioning locking buckle, effectively reducing the possibility of loosening. When the positioning locking buckle detaches from the positioning locking block, an audible and visual alarm automatically sounds, reminding staff to adjust the buckle promptly. This effectively prevents the wire harness connector from being pulled apart when the positioning locking buckle falls off, ensuring the stability of the connection and improving the connector's performance. A flexible protective sleeve prevents excessive bending of the wire harness, which could cause the insulation to crack. The sliding support plate expands the rubber sealing ring, facilitating the mating of the first and second connecting seats and effectively improving the mating efficiency of the wire harness connector.

[0026] The warning structure also includes a push-button switch 602 and a clamping elastic element 603; the push-button switch 602 is located on the upper part of the left guide sliding block 601; there are two clamping elastic elements 603, and the two guide sliding blocks 601 are elastically connected to the limit support frame 5 through the two clamping elastic elements 603.

[0027] The specific usage and function of this embodiment are as follows: When connecting the wire harness, the wire harness is fixed in the first connecting seat 1 and the second connecting seat 2, and then the first connecting seat 1 and the second connecting seat 2 are inserted together to complete the wire harness connection. After the connection is completed, the positioning locking buckle 3 is fastened to the outside of the positioning locking block 4 to fix the first connecting seat 1 and the second connecting seat 2 together.
