[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: a wiring terminal for a car windshield wiper, including a wiring terminal body 1, the wiring terminal body 1 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The wiring terminal body 1 can be installed on the vehicle and can be connected to the terminal connector. The wiring terminal body 1 is an important bridge connecting the wiper motor and the vehicle electrical system. A positioning component 2 is provided on the front side of the outer wall of the wiring terminal body 1. The positioning component 2 can fix the terminal connector on the wiring terminal body 1. The front surface of the wiring terminal body 1 is provided with a guide Toward component 3, the guide component 3 can provide a guiding function for the terminal connector when it is installed, so as to avoid collision between the terminal connector and the terminal body 1 due to the narrow space when it is installed in the gap of the car. The positioning component 2 includes a positioning ring 21, the inner wall of the positioning ring 21 is elastically connected with a moving ring 23 through a compression spring 22, and the upper surface of the moving ring 23 is fixedly connected with a protrusion 24, and the moving ring 23 and the protrusion 24 will move synchronously. A sliding groove 201 is provided on the upper surface of the positioning ring 21, and the sliding groove 201 and the protrusion 24 fit together. The protrusion 24 is slidably connected to the inner wall of the sliding groove 201 and slides in the front and rear directions.

[0032] Reference Figure 1 - Figure 3 The positioning assembly 2 also includes a block 26, a slider 27 is fixedly connected to the front surface of the block 26, the block 26 passes through the lower surface of the terminal body 1, and a moving block 25 is fixedly connected to the upper surface of the protrusion 24. The moving block 25 is located outside the positioning ring 21 and can block the slide groove 201, which can provide a protection for the compression spring 22, including preventing impurities from entering the positioning ring 21 and causing blockage, thereby affecting the normal use of the compression spring 22.

[0033] Reference Figure 1 - Figure 3 The guide assembly 3 includes a rotating shaft 33, a round rod 32 is fixedly connected to the outer wall of the rotating shaft 33, and a rubber sleeve 31 is fixedly connected to the outer wall of the round rod 32. The rotating shaft 33, the round rod 32 and the rubber sleeve 31 will rotate synchronously.

[0034] Reference Figure 1 - Figure 3 The positioning ring 21 is fixedly connected to the front side of the outer wall of the terminal body 1, and the terminal body 1 provides support for the positioning ring 21. One end of the compression spring 22 is fixedly connected to the rear surface of the moving ring 23, and the other end of the compression spring 22 is fixedly connected to the inner wall of the rear side of the positioning ring 21. When the moving ring 23 moves backward, it will squeeze the compression spring 22 to generate a reaction force. The moving ring 23 is slidably connected to the outer wall of the terminal body 1 and slides in the front and back directions.

[0035] Reference Figure 1 - Figure 3The upper surface of the block 26 is set to an arc surface, and the lower surface of the block 26 is set to an arc surface. When the arc surface of the block 26 is squeezed, the block 26 will slide longitudinally. When the movable ring 23 is pushed to the front end inside the positioning ring 21 by the compression spring 22, the lower surface of the block 26 will be blocked. The block 26 can be clamped in the groove on the terminal connector. The shape and position of the block 26 can be changed according to actual use, and it is not just one shape in the drawings of the utility model specification. The slider 27 is slidably connected to the inner wall of the terminal body 1.

[0036] Reference Figure 1 - Figure 3 There are multiple groups of sliders 27 and blocks 26, which are arranged in a circular array with the center of the terminal body 1 as the origin, and can limit the terminal connector from four directions.

[0037] Reference Figure 1 - Figure 3 An annular depression is provided on the front surface of the terminal body 1. When the terminal connector and the terminal body 1 are plugged in, they will move along the inclined surface of the depression. The depression can play a guiding role. The rotating shaft 33 is rotatably connected to the inner wall of the terminal body 1. The rubber sleeve 31, the round rod 32, and the rotating shaft 33 are located in the depression.

[0038] Reference Figure 1 - Figure 3 The rubber sleeve 31 is made of rubber and is soft.

[0039] Working principle: When the device is used, first push the moving block 25 backward to drive the protrusion 24 and the moving ring 23 to move backward. The moving ring 23 moving backward will release the obstruction of the block 26 and squeeze the compression spring 22 to generate a reaction force. Then the terminal connector and the terminal body 1 are plugged in. When plugging in, the terminal connector will move along the recessed part of the front surface of the terminal body 1 and will collide with the rubber sleeve 31. During the collision, the rubber sleeve 31 is soft in texture and can play a buffering role, so it can protect the terminal connector and prevent it from being damaged.

[0040] When the terminal connector is inserted into the terminal body 1, the arc surface of the card block 26 will be squeezed to make the four groups of card blocks 26 open synchronously. When the terminal connector and the terminal body 1 are completely plugged in, the depression on the terminal connector will be aligned with the card block 26. At this time, the moving block 25 is released, and the reaction force of the compression spring 22 will push the moving ring 23, the protrusion 24 and the moving block 25 to move forward. The moving ring 23 moving forward will squeeze the arc surface of the card block 26 to make it engage with the depression of the terminal connector, forming a limit, thereby ensuring the stability of the terminal connector and the terminal body 1 when connected.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
