Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a new type of miniaturized low-voltage power-off switch connector assembly. Background Technique

[0002] Low-voltage power-off switch connectors are widely used in new energy and hybrid vehicles. They are key safety components for realizing the electrical connection and disconnection of in-vehicle electrical equipment. The reliability and sealing performance during connection directly determine the stability of in-vehicle circuit connection, and even affect the safe driving of the vehicle; the reliability and waterproof performance during disconnection ensure whether the high-voltage circuit is effectively disconnected, which plays a key role in the personal safety of maintenance personnel. With the development of new energy vehicles, as an important part of them, connectors also face higher technical requirements. Therefore, it is required that low-voltage power-off switch connectors have high reliability and good waterproof performance.

[0003] At present, there are two common types of low-voltage power-off switch connectors:

[0004] The first type disconnects the circuit by completely separating the male and female ends, but there are the following problems: 1) When maintaining, when completely separated, there is a risk of water ingress in the male and female end connectors; 2) Disconnecting the power requires the complete separation of the connectors, and the operation is cumbersome.

[0005] The other type does not completely separate when the male and female end circuits are disconnected, but there is also a problem that when the circuit is disconnected, the connector has no sealing and waterproof function.

[0006] Moreover, the above two types of low-voltage power-off switch connectors usually use a single sealing plug for sealing, and the terminal center distance is set relatively large, resulting in a relatively large overall size of the connector, which does not conform to the miniaturization trend of new energy vehicle connectors.

[0007] In summary, it is necessary to design a low-voltage power-off switch connector that is highly reliable, has good sealing and waterproof performance and is miniaturized when in the disconnected state on the premise of ensuring the reliability of the low-voltage power-off switch connector in the connected state.

[0048] Example 5. Based on Example 4, a new type of miniaturized low-voltage power-off switch connector assembly, as shown in Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 16 and Figure 17 . The CPA2-2 includes a CPA stop structure 2-2-1. An insertion pin sheath self-locking structure 2-1-2 is connected to the insertion pin sheath main body 2-1. The bottom of the insertion pin sheath self-locking structure 2-1-2 is connected to the insertion pin sheath main body 2-1, and the top of the insertion pin sheath self-locking structure 2-1-2 extends obliquely away from the insertion pin sheath main body 2-1; a hanging stop block 2-1-2-2 is connected to the bottom of the insertion pin sheath self-locking structure 2-1-2; a first hanging stop portion 1-1-2 is provided in the socket sheath main body 1-1.

[0049] Example 6. Based on Example 5, a new type of miniaturized low-voltage power-off switch connector assembly, as shown in Figure 10 , Figure 11 , Figure 16 and Figure 17 . The top surface of the hanging stop block 2-1-2-2 is a second hanging surface 2-1-2-2-1, and the bottom surface is a second stop surface 2-1-2-2-2. The second hanging surface 2-1-2-2-1 is in stop cooperation with the first hanging surface 1-1-2-2, and the second stop surface 2-1-2-2-2 is in stop cooperation with the first stop surface 1-1-2-1. That is, when the connector is in the OFF state, the second stop surface 2-1-2-2-2 is in stop cooperation with the first stop surface 1-1-2-1; when the connector is in the ON state, the second hanging surface 2-1-2-2-1 is in stop cooperation with the first hanging surface 1-1-2-2.

[0050] Example 7. Based on Example 6, a new type of miniaturized low-voltage power-off switch connector assembly, as shown in Figure 5 ,Figure 10 , Figure 11 , Figure 16 and Figure 17 As shown, the top of the first hanging stop portion 1-1-2 is connected to the socket sheath main body 1-1, and the bottom of the first hanging stop portion 1-1-2 extends obliquely away from the socket sheath main body 1-1.

That is, when the hanging stop block 2-1-2-2 moves below the first hanging stop portion 1-1-2, the bent bottom of the first hanging stop portion 1-1-2 is directly above the hanging stop block 2-1-2-2, and the bent bottom of the first hanging stop portion 1-1-2 is in perpendicular contact with the hanging stop block 2-1-2-2, avoiding the situation that the hanging stop block 2-1-2-2 is easily disengaged from the blocking of the first hanging stop portion 1-1-2, and strengthening the reliability of the connection between the pin sheath main body 2-1 and the socket sheath main body 1-1.

[0052] Embodiment 9, based on Embodiment 8, a new type of miniaturized low-voltage power-off switch connector assembly, as Figure 1 , Figure 3 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17As shown, a pressing unlocking block 2-1-2-1 is provided at the top of the pin sheath self-locking structure 2-1-2. The pressing unlocking block 2-1-2-1 is in a blocking fit with the socket sheath main body 1-1. The pin sheath self-locking structure 2-1-2 is a cantilever structure. One end of the pin sheath self-locking structure 2-1-2 is connected to the pin sheath main body 2-1, and the other end extends obliquely. The pressing unlocking block 2-1-2-1 is located at the obliquely extending end. The suspended end of the pin sheath self-locking structure 2-1-2 is in a blocking fit with the socket sheath main body 1-1. At this time, the space between the pin sheath self-locking structure 2-1-2 and the pin sheath main body 2-1 is the insertion space of the CPA stop structure 2-2-1. When secondary locking is required, pressure is applied to the pressing unlocking block 2-1-2-1, and the hanging stop block 2-1-2-2 on the pin sheath self-locking structure 2-1-2 is elastically deformed by the force and disengages from the first stop surface 1-1-2-1 of the socket sheath main body 1-1. At this time, the pin sheath assembly 2 can be moved downward for assembly. When the second hanging surface 2-1-2-2-1 on the hanging stop block 2-1-2-2 is in a blocking fit with the first hanging surface 1-1-2-2 of the first hanging stop portion 1-1-2, the CPA stop structure 2-2-1 is pressed downward, and the bottom of the CPA stop structure 2-2-1 moves below the pin sheath self-locking structure 2-1-2 and supports the pin sheath self-locking structure 2-1-2, that is, the secondary locking is completed. At this time, the connector assembly reaches the ON state (working state).

[0053] Embodiment 10, based on Embodiment 1 or 9, a novel miniaturized low-voltage power-off switch connector assembly, as Figure 1 , Figure 3 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 , Figure 16 and Figure 17 shown, a safety lock hole shielding portion 1-1-3 is provided on the socket sheath main body 1-1, and a safety lock hole structure 2-1-3 is provided on the pin sheath main body 2-1. The safety lock hole structure 2-1-3 is in an insertion fit with the safety lock hole shielding portion 1-1-3. Safety marks "OFF" and "ON" are provided on the safety lock hole structure 2-1-3. When the "OFF" mark is exposed and the "ON" mark is hidden, it prompts the maintenance personnel of the circuit state and further ensures the safety during maintenance. The setting of the safety lock hole structure 2-1-3 is for warning the maintenance personnel on the one hand, and on the other hand, the safety lock hole structure 2-1-3 can be hung with a general safety lock to further ensure the safety during maintenance.

[0054] When the low-voltage power-off switch connector assembly is in the OFF (maintenance) state, the hanging stop block 2-1-2-2 and the first stop surface 1-1-2-1 are in stop cooperation, and it cannot be further assembled to the ON (working) state. At the same time, the first stop portion 2-1-1 and the first hanging portion 1-1-1 are in stop cooperation and cannot be separated. At the same time, the safety lock hole structure 2-1-3 is exposed and can be hung with a general safety lock, further ensuring safety during maintenance.

[0055] When the low-voltage power-off switch connector assembly is in the ON (working) state, the hanging stop block 2-1-2-2 and the first hanging stop portion 1-1-2 are in stop cooperation. At the same time, the CPA stop structure 2-2-1 is pressed, and the bottom of the CPA stop structure 2-2-1 moves below the pin sheath self-locking structure 2-1-2 and supports the pin sheath self-locking structure 2-1-2 to ensure the stable and reliable electrical connection of the connector. And this product is shipped in the OFF state as a whole, reducing the assembly process at the client side. It has a simple structure and reliable function, and can effectively ensure safety during vehicle maintenance and stability during normal operation.

[0056] When implementing Embodiment 10, the socket sheath assembly 1 and the pin sheath assembly 2 are assembled in sequence. Then, the pin sheath assembly 2 is inserted from the top of the socket sheath assembly 1. After insertion, the first stop portion 2-1-1 and the first hanging portion 1-1-1 are in stop cooperation and cannot be separated. The hanging stop block 2-1-2-2 and the first stop surface 1-1-2-1 are in stop cooperation. The safety label "OFF" on the safety lock hole structure 2-1-3 is exposed. The pressing unlocking block 2-1-2-1 on the pin sheath self-locking structure 2-1-2 and the socket sheath main body 1-1 are in stop cooperation. At this time, the low-voltage power-off switch connector assembly is in the OFF (maintenance) state, which is also the shipping state of this product;

[0057] When the low-voltage power-off switch connector assembly needs to be adjusted to the ON (working) state, pressure is applied to the pressing unlocking block 2-1-2-1. The hanging stop block 2-1-2-2 on the pin sheath self-locking structure 2-1-2 is elastically deformed by the force and disengages from the first stop surface 1-1-2-1 of the socket sheath main body 1-1. At this time, the pin sheath assembly 2 can be moved downward for assembly. When the second hanging surface 2-1-2-2-1 on the hanging stop block 2-1-2-2 and the first hanging surface 1-1-2-2 of the first hanging stop portion 1-1-2 are in stop cooperation, the CPA stop structure 2-2-1 is pressed downward. The bottom of the CPA stop structure 2-2-1 moves below the pin sheath self-locking structure 2-1-2 and supports the pin sheath self-locking structure 2-1-2, that is, the secondary locking is completed. At this time, the connector assembly reaches the ON state (working state).
