Description

Technical Field

[0001] The utility model relates to the technical field of wire harness connectors, and particularly relates to an automobile wire harness connector with high plugging and unplugging resistance. Background Art

[0002] A wire harness connector is a type of terminal. A connector, also known as a plug connector, consists of a plug and a socket. The connector is a relay station for wire harnesses in an automobile circuit. Wire harness connector products are applied to automobiles, household appliances, instruments, office equipment, commercial machines, leads of electronic components, electronic control boards, and are used in digital products, household appliances, and the automotive industry. With the increase in automobile functions and the widespread application of electronic control technology, there are more and more electrical components and wires.

[0003] After the existing automobile wire harness connector is plugged and unplugged, it is usually connected by a buckle. After repeated plugging and unplugging, the elastic components are repeatedly deformed and fatigued, resulting in a decrease in the connection stability of the wire harness connector and a risk of disconnection. Content of the Utility Model

[0004] The purpose of the utility model is to provide an automobile wire harness connector with high plugging and unplugging resistance, which has the advantage of high plugging and unplugging resistance and solves the problem of reduced connection stability caused by repeated plugging and unplugging of the current automobile wire harness connector.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an automobile wire harness connector with high plugging and unplugging resistance, including a connection main body formed by plugging a male plug and a female plug. The two sides of the male plug bulge outwards to form clamping grooves. One end of the female plug is embedded inside the male plug, and limiting plates that can slide and be embedded inside the clamping grooves are constructed on both sides of the female plug. A limiting groove is opened at one end of the limiting plate extending into the clamping groove. Clamping mechanisms that are clamped into the limiting grooves are arranged on both sides of the clamping groove. Each clamping mechanism includes a limiting mechanism and a moving mechanism, and the moving mechanism is vertically arranged above the limiting mechanism.

[0006] Preferably, the limiting mechanism includes a sliding block. A first arc block that is embedded inside the limiting groove is arranged on one side of the sliding block facing the inside of the male plug, and a second arc block is installed at the top of the sliding block. The first arc block is provided with an arc surface facing the female plug, and the second arc block is provided with an arc surface facing the moving mechanism.

[0007] Preferably, a plurality of clamping blocks are symmetrically installed on the side surface of the sliding block, and a limiting frame is installed on one side of the sliding block facing the first arc block. The sliding block can be slidably embedded inside the limiting frame, and a spring that abuts against the side surface of the sliding block is installed inside the limiting frame.

[0008] Preferably, the movable mechanism includes a movable plate. A third arc-shaped block is provided at the bottom end of the movable plate. The third arc-shaped block is provided with an arc surface facing the limiting mechanism. A connecting plate is installed at the top end of the movable mechanism. One side of the connecting plate is attached to the side surface of the male plug, and a limiting frame is sleeved on the connecting plate.

[0009] Preferably, the connecting plate is a plate-shaped structure with a T-shaped cross-section, and its two T-shaped ends are embedded in the limiting frame.

[0010] Preferably, the side surface of the limiting frame is fixedly connected to the side surface of the male plug, and the limiting frame is placed above the card slot and provided with a gap.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By setting a male plug, a card slot, a female plug, a limiting plate, a limiting groove, a limiting mechanism and a movable mechanism, when the female plug is inserted into the male plug, the limiting plates on both sides of the female plug are embedded in the card slot for limiting, and the limiting mechanism slides and is embedded in the limiting groove to fix the male plug and the female plug. Instead of using the method of setting an elastic plate with bumps on the connecting body for fixation, it can avoid the phenomenon of fatigue of the elastic plate after repeated plugging and unplugging of the connector, and improve the plugging and unplugging resistance of the connector.

[0013] 2. By setting a slider, a first arc-shaped block, a second arc-shaped block, a limiting frame, a spring, a movable plate and a third arc-shaped block, when the limiting plate abuts against the first arc-shaped block, the slider is squeezed towards the inside of the limiting frame. When the first arc-shaped block moves to the limiting groove, the spring pushes the slider to embed the first arc-shaped block into the limiting groove to complete the fixation. During disassembly, by pressing the connecting plate, the third arc-shaped block at the bottom end of the movable plate abuts against the second arc-shaped block to move the first arc-shaped block out of the limiting groove, quickly releasing the fixation between the male plug and the female plug, which is convenient for later disassembly.

On the side surface of the slider 501, a plurality of clamping blocks 504 are symmetrically installed, and on the side of the slider 501 facing the first arc block 502, there is a limiting frame 505 installed. The slider 501 can slide and embed into the limiting frame 505, and inside the limiting frame 505, there is a spring 506 that abuts against the side surface of the slider 501. The moving mechanism 6 includes a moving plate 601. At the bottom end of the moving plate 601, there is a third arc block 602. The third arc block 602 has an arc surface facing the limiting mechanism 5. At the top of the moving mechanism 6, there is a connecting plate 603 installed.

[0024] Working principle: During the operation of the present utility model, the moving plate 601 is embedded into the clamping groove 201, then the connecting plate 603 is inserted upward from the bottom end of the limiting frame 604 to complete the installation. Then the slider 501 is embedded into the clamping groove 201. By the second arc block 503 abutting against the third arc block 602, the support for the moving plate 601 is completed. Then the spring 506 is embedded into the limiting frame 505 to complete the assembly. During plugging, by the limiting plate 301 abutting against the first arc block 502, the slider 501 is extruded towards the inside of the limiting frame 505. When the first arc block 502 moves to the position of the limiting groove 302, the spring 506 pushes the slider 501 to embed the first arc block 502 into the limiting groove 302 to complete the fixation. During disassembly, by pressing the connecting plate 603, the third arc block 602 at the bottom end of the moving plate 601 abuts against the second arc block 503 to move the first arc block 502 out of the limiting groove 302, quickly releasing the fixation between the male plug 2 and the female plug 3.
