Description

Technical Field

[0001] The utility model relates to the technical field of automobile connector equipment, in particular to an automobile connector with a locking mechanism. Background Art

[0002] The automotive connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked parts in the circuit or isolated circuits, so that current can flow and the circuit can achieve the predetermined function. In the prior art, when the automotive connector is in use, there is a gap at the connection port, and dust is easily accumulated inside the connector. After a long period of use, a lot of dust will accumulate, causing the connector to malfunction. At the same time, the plug terminal and the socket terminal are not inserted firmly enough to achieve electrical connection, and the vibration of the car causes the battery replacement connector to fall off.

[0003] For example, the authorized patent document with application number CN202021018831.9 discloses an automotive connector socket with a temperature sensor, including a connecting line and a second groove, a connecting block is provided at the right end of the connecting line, and a left fixed seat is installed above the right end of the connecting block, a card seat is provided above the right end of the left fixed seat, and a thread is installed below the card seat, a card block is provided below the thread, a transmission line is provided at the right end of the right fixed seat, a first groove is provided at the right end of the temperature sensor, the second groove is located below the right end of the left fixed seat, a guide rod is provided above the right end of the rubber ring, and a power cord is provided at the right end of the third groove. Compared with the existing ordinary connector socket, the automotive connector socket with a temperature sensor has an anti-drop connection inside and a temperature sensing structure. While adding the structure, the performance of the entire connector socket is greatly improved. The improved connector socket effectively meets people's usage needs.

[0004] The above patent has the problem that when the automobile connector is in use, there is a gap at the connection port, and dust is easy to accumulate inside the connector. After a long period of use, a large amount of dust will accumulate. At the same time, the plug terminal and the socket terminal are not firmly connected when they are plugged in to achieve electrical connection. Therefore, we need to provide an automobile connector with a locking mechanism. Utility Model Content

[0005] The purpose of the utility model is to provide an automobile connector with a locking mechanism, by plugging the plug body and the socket body, the plug block at the bottom of the upper plate body will squeeze the two clamping blocks, the clamping block drives the rotating rod to rotate on the mounting seat, and at the same time drives the torsion spring to deform until the plug block is located between the two clamping blocks for clamping and fixing, thereby having a preliminary fixing effect on the installation of the plug body and the socket body, and at the same time rotating the limit bolt, since the surface of the limit bolt is threadedly installed with the internal thread of the upper plate body, and the limit bolt is located on one side of the clamping block, it can effectively prevent the clamping block from rotating, and the fixation between the plug body and the socket body is more firm, solving the problems raised in the above-mentioned background technology.

A clamping block is fixed on the surface of the rotating rod, and a torsion spring for elastic support of the clamping block is movably sleeved on the surface of the rotating rod, and the surface of the insertion block is clamped between the two clamping blocks.

[0012] Preferably, two limiting bolts are installed on the internal threads of the upper plate body, and the bottom of the limiting bolts is arranged on one side of the clamping block.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model plugs the plug body and the socket body together, and the plug block at the bottom of the upper plate body squeezes the two clamping blocks. The clamping block drives the rotating rod to rotate on the mounting seat, and at the same time drives the torsion spring to deform until the plug block is located between the two clamping blocks for clamping and fixing, thereby achieving a preliminary fixing effect on the installation of the plug body and the socket body. At the same time, the limiting bolt is rotated. Since the surface of the limiting bolt is threadedly installed with the internal thread of the upper plate body and the limiting bolt is located on one side of the clamping block, the rotation of the clamping block can be effectively prevented, and the fixation between the plug body and the socket body is more secure.

[0035] Specifically, when the plug body 1 is inserted into the socket body 2, the sealing ring body 51 at the bottom of the plug body 1 will squeeze the movable ring body 54 to move in the annular groove 52, and at the same time the four springs 53 are compressed until the sealing ring body 51 is located in the annular groove 52, thereby enhancing the sealing effect.

[0036] Four guide cylinders 9 are fixedly installed on the top of the lower plate body 4, and guide rods 10 adapted to the four guide cylinders 9 are fixedly installed on the bottom of the upper plate body 3;
