[0002] Automotive connectors are a component frequently encountered by electronic engineers. They bridge blocked or isolated circuits within a circuit, allowing current to flow and enabling the circuit to function as intended. Plug-in male-to-female automotive connectors are a common electrical connection device, widely used in various electronic devices. The main feature of this connector is that it includes a flame-retardant female plug and a flame-retardant male receptacle. The insert inserts into the flame-retardant female plug, and the spring inserts into the flame-retardant male receptacle. When the flame-retardant female plug is inserted into the flame-retardant male receptacle, the insert inserts into the spring, connecting the circuit. When the flame-retardant female plug and the flame-retardant male receptacle are separated, the circuit is disconnected.

[0003] The existing flame-retardant female plug is provided with an insert slot for inserting the insert, and the two ends of the insert slot are connected, one end is used to insert the insert, and the other end is used to facilitate the insertion of the insert spring when the flame-retardant female plug is buckled with the flame-retardant male socket. However, the end of the existing flame-retardant female plug where the insert spring is inserted has a directional structure. Therefore, when the insert spring is inserted from this port, it is easy for the port to be too large to play a guiding role, resulting in the insert spring being unable to accurately insert into the insert, resulting in the insert and the insert spring being inserted crookedly, which ultimately easily affects the connectivity between the insert and the insert spring in the later stage, so it needs to be improved.

For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] Example 1:

[0020] See also Figure 1-3 The utility model provides a nylon flame retardant female plug for a battery vehicle connector, including a nylon flame retardant shell 1, the nylon flame retardant shell 1 is provided with more than one plug slot 2, the two ends of the plug slot 2 are connected and are respectively located on the two opposite end surfaces of the nylon flame retardant shell 1, one end of the plug slot 2 is used to plug in the plug, and the other end of the plug slot 2 is used to plug in the plug spring. A guide inclined plate 3 and two guide inclined steps 4 are provided on the plug slot 2 relative to the end for plugging in the plug spring. The two guide inclined steps 4 are arranged parallel to each other, and the inclined surfaces 401 on the two guide inclined steps 4 cooperate with the guide inclined plate 3 to form a funnel slot 5 for serving as an entrance for plugging in the plug spring, and it should be noted that the central axis of the funnel slot 5 is the same axis as the central axis of the plug slot 2 below for plugging in the plug.

[0021] As a preferred method, in order to further ensure that the position displacement phenomenon does not occur when the plug spring and the plug are plugged in later, each plug slot 2 is provided with a guide inclined table 6 for guiding the plug. In this embodiment, by providing the guide inclined table 6 in the plug slot 2, when the existing plug is inserted from the plug slot 2, the plug is not moved. Figure 2 When the insert is inserted into the slot 2 of the port, as the insert continues to be inserted, when the insert is inserted slowly close to the guide inclined table 6, Figure 3 When the opening of the funnel slot 5 is in the upper state, the insert continues to move as shown in FIG. Figure 3 When it moves upward, under the operation of the guiding inclined table 6, it is ensured that the upper part of the plug can accurately follow the inclined direction of the guiding inclined table 6 and enter the position just below the funnel slot 5. Then, with the insertion of the plug spring in the upper funnel slot 5, it is finally ensured that the plug spring and the plug can be accurately plugged together without position displacement or crooked insertion.

[0022] Preferably, in order to improve the overall strength, two reinforcing ribs 7 are provided in each insert slot 2. The starting point of the reinforcing rib 7 starts from the end face of the insert slot 2 for inserting the insert, and the node position of the reinforcing rib 7 exceeds one half of the length of the insert slot 2. In this embodiment, the strength and hardness of the entire nylon flame retardant shell 1 are further improved by adding the reinforcing rib 7.

[0023] Preferably, in order to facilitate later positioning, a limiting notch 8 extending along the length direction of the nylon flame retardant shell 1 is provided on the side of the nylon flame retardant shell 1, and the limiting notch 8 is used to cooperate with the reinforcing ribs on the inner side of the flame retardant male socket. In this embodiment, a limiting notch 8 is provided on the side of the nylon flame retardant shell 1. Later, since the nylon flame retardant shell 1 needs to be inserted into the existing flame retardant male socket, and the existing flame retardant male socket has a protruding reinforcing rib on the inner side, the reinforcing rib on the inner side of the flame retardant male socket can not only increase the strength of the flame retardant male socket, but also serve as a guide strip. When the nylon flame retardant shell 1 is inserted into the flame retardant male socket, the limiting notch 8 moves along the protruding reinforcing rib, and finally ensures that the entire nylon flame retardant shell 1 extends into the flame retardant male socket, and the protruding reinforcing rib cooperates with the limiting notch 8 to realize the limited installation of the nylon flame retardant shell 1 (to position the nylon flame retardant shell 1 in the flame retardant male socket), and there will be no problem of wrong installation direction.

[0024] Preferably, in order to improve the connection strength, the nylon flame retardant shell 1 is provided with an extension portion 9 on the side of one end facing the plug spring, and a hook through hole 12 is provided on the extension portion 9. The extension portion 9 is integrally formed with the nylon flame retardant shell 1, and a reinforcing rib 10 is provided between the extension portion 9 and the nylon flame retardant shell 1. In this embodiment, by providing the hook through hole 12 and providing a hook that cooperates with the hook through hole 12 on the side of the flame retardant male socket, the snap-fitting effect of the flame retardant male socket and the flame retardant female plug of this application is finally achieved.

[0025] Preferably, in order to improve the connection strength, a reinforcing plate 11 is provided on the outer side of one end face of the nylon flame retardant shell 1 for inserting the plug, and the extension portion 9 is located on one side of the reinforcing plate 11. The thickness of the reinforcing plate 11 is 1.75±0.2 mm. In this embodiment, by adding a reinforcing plate 11 to one end face of the nylon flame retardant shell 1, not only the strength of the overall female plug is improved, but also it is convenient to play a limiting role when the female plug is inserted into the flame retardant male socket, which is convenient for later disassembly.

[0026] The operation of this structure is as follows: first, insert the existing plug spring into the existing flame retardant male socket, partially exposing the flame retardant male socket, and then remove the existing plug from the existing flame retardant male socket. Figure 2 Insert the plug slot 2 into the port to ensure that the plug head is located directly below the funnel slot 5, and then connect the flame-retardant male socket with a nylon flame-retardant female plug for a battery vehicle connector of this application. During the plugging process, the plug spring that is partially exposed from the flame-retardant male socket guides the head of the plug spring under the action of the guide inclined plate 3 and the two guide inclined ladders 4, so that the plug spring can smoothly and quickly enter along the funnel slot 5 and smoothly connect with the lowered plug. Therefore, this structure provides a funnel slot 5 for guiding at one end of the plug slot 2 to ensure that the jack position will not be offset when the plug spring is plugged in, which ultimately leads to the situation where the conductive performance is affected by the offset of the plug position in the later stage.

[0027] 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 scope of protection of the present invention.
