Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, specifically a self-locking anti-reverse pin automotive connector. Background Technology

[0002] Automotive connectors are a type of component that electronic engineers frequently encounter. Their function is very simple: to bridge the gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Generally, there are nearly a hundred types of connectors used in automobiles, and a single model may use as many as several hundred connectors. As people's requirements for automobiles become increasingly higher in terms of safety, environmental protection, comfort, and intelligence, the application of automotive electronic products is increasing day by day.

[0003] In the existing technology, when a car is driving on bumpy roads or other bad road conditions, some of the car's internal connectors may frequently vibrate or shake. Over time, this can easily cause the plugs and sockets of the car connectors to loosen or even separate and fall off, resulting in abnormal car functions. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking anti-reverse pin automotive connector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A self-locking anti-removal pin automotive connector for locking between a socket housing and a plug housing includes two anti-removal structures symmetrically installed between the socket housing and the plug housing. Each anti-removal structure includes a pressure plate, a connecting plate, plastic sheets, and a ratchet. The pressure plate is elastically rotatably connected to the socket housing, the connecting plate is fixedly connected to the plug housing, a plurality of plastic sheets are evenly and obliquely fixedly connected to the connecting plate, the ratchet is fixedly connected to the pressure plate and is located between the pressure plate and the socket housing, the connecting plate is slidably connected between the ratchet and the socket housing, and the plastic sheets are in contact with the ratchet.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a self-locking anti-reverse pin automotive connector for locking between a socket housing 1 and a plug housing 2. It includes two anti-reverse structures 3, which are symmetrically installed between the socket housing 1 and the plug housing 2. Each anti-reverse structure 3 includes a pressure plate 31, a connecting plate 32, plastic sheets 33, and a ratchet 35. The pressure plate 31 is elastically rotatably connected to the socket housing 1, the connecting plate 32 is fixedly connected to the plug housing 2, multiple plastic sheets 33 are evenly and obliquely fixedly connected to the connecting plate 32, the ratchet 35 is fixedly connected to the pressure plate 31 and is located between the pressure plate 31 and the socket housing 1, the connecting plate 32 is slidably connected between the ratchet 35 and the socket housing 1, and the plastic sheets 33 are in contact with the ratchet 35.

[0021] Please see Figure 1 and Figure 2 In this embodiment, the plug housing 2 can be directly inserted into the socket housing 1, so that the electrical contacts inside the socket housing 1 and the plug housing 2 can be connected to each other. At this time, the plug housing 2 can drive the connecting plate 32 to gradually approach the pressure plate 31. The connecting plate 32 can drive multiple plastic pieces 33 to move synchronously. As the socket housing 1 and the plug housing 2 are connected, the plastic pieces 33 gradually come into contact with the ratchet 35. After being squeezed by the ratchet 35, the plastic pieces 33 will undergo elastic deformation in the vertical direction, so that the socket housing 1 and the plug housing 2 can be connected smoothly. If there is a tendency for the socket housing 1 and the plug housing 2 to separate... Then the plug housing 2 will drive the connecting plate 32 and the plastic sheet 33 on its surface to move in the opposite direction. However, the plastic sheet 33 will be obstructed by the fixed ratchet 35, thus achieving self-locking between the socket housing 1 and the plug housing 2 to prevent the electrical contacts inside the socket housing 1 and the plug housing 2 from being dislodged. When it is necessary to properly separate the socket housing 1 and the plug housing 2, the operator can press the pressure plate 31, causing the pressure plate 31 to lift the metal spring 36 on its surface. At this time, the metal spring 36 will separate from the plastic sheet 33, thus facilitating the separation of the socket housing 1 and the plug housing 2.

[0022] It should be noted that the improvements made in this embodiment are based on the socket housing 1 and the plug housing 2, and do not make any changes to the internal electrical contacts, wiring harness, insulator and remaining accessories. As an automotive connector itself, the socket housing 1, the plug housing 2 and the internal electrical contacts, wiring harness, insulator and remaining accessories can realize the complete function of the automotive connector. Furthermore, the specific connection relationship and working principle of the electrical contacts, wiring harness, insulator and remaining accessories are technical means well known to those skilled in the art, and will not be described in detail here.

[0023] The anti-detachment structure 3 also includes a metal spring 36, which is fixedly connected between the pressure plate 31 and the socket housing 1.

[0024] Please see Figure 2 In this embodiment, the metal spring 36 realizes the elastic connection between the pressure plate 31 and the socket housing 1. When the pressure plate 31 is pressed, the pressure plate 31 can squeeze the metal spring 36 to deform and store energy. When the pressure plate 31 is released, the metal spring 36 can release energy to drive the pressure plate 31 to reset.

[0025] It should be noted that the metal spring 36 is U-shaped or V-shaped. The U-shaped or V-shaped metal spring 36 makes it easier for the operator to press the socket housing 1. Alternatively, in this embodiment, the metal spring 36 can be replaced with a spring.

[0026] The anti-detachment structure 3 also includes two side plates 34, which are symmetrically fixedly connected to the pressure plate 31. The side of the side plate 34 is in contact with the surface of the socket housing 1, and the side of the connecting plate 32 is in contact with the surface of the side plate 34.

[0027] Please see Figure 1 and Figure 4 The side plate 34 can support the pressure plate 31 when the pressure plate 31 is in the normal state, so that the surface of the pressure plate 31 is parallel to the surface of the socket housing 1, so that the ratchet 35 can be in the right position to cooperate with the plastic sheet 33. Furthermore, the two side plates 34 can limit and guide the connecting plate 32 when it enters below the pressure plate 31, so that the connection between the plug housing 2 and the socket housing 1 can be more accurate.

[0028] It also includes an auxiliary structure 4, which includes a foot plate 42 and a limiting arm 43. The foot plate 42 is fixedly connected to the side of the side plate 34, and the limiting arm 43 is rotatably connected to the socket housing 1. One side of the foot plate 42 is in contact with the socket housing 1, and the other side of the foot plate 42 is in contact with the limiting arm 43.

[0029] Please see Figure 3 and Figure 4 When the pressure plate 31 is in the normal state, the bottom surface of the side plate 34 is in contact with the surface of the socket housing 1, and the surface of the foot plate 42 is also in contact with the surface of the socket housing 1. At this time, the foot plate 42 is in a horizontal state. By rotating the limiting arm 43, the foot plate 42 can be covered on the surface of the socket housing 1 to achieve vertical limitation of the foot plate 42. Since the foot plate 42 is in a locked state, the operator cannot lift the ratchet 35 by pressing the pressure plate 31. In the process of vehicle operation, the limiting arm 43 will not be separated from the foot plate 42 due to vibration or shaking. Therefore, the connection between the socket housing 1 and the plug housing 2 can be further reinforced.

[0030] Limiting arms 43 are provided on opposite sides of the socket housing 1. The auxiliary structure 4 also includes a stop bar 41, with both ends of the stop bar 41 fixedly connected to one end of each of the two limiting arms 43.

[0031] Please see Figure 4 By setting the stop lever 41, the two limiting arms 43 on the socket housing 1 can be connected as a whole. At this time, pulling the stop lever 41 alone can control the movement of the two limiting arms 43 at the same time, so as to simplify the separation steps of the socket housing 1 and the plug housing 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
