Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and more specifically to a safety electrical connector suitable for high voltage. Background Technology

[0002] Electrical connectors are components that electronic engineers frequently encounter. Their function is quite simple: to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Electrical connectors are indispensable components in electronic devices, and their forms and structures are highly varied. Different types of electrical connectors exist depending on the application, frequency, power, and environment. Current electrical connectors typically consist of a plug and a socket, as disclosed in Chinese utility model patents CN103515774B and CN116581587B. When these two are plugged together, they can conduct current and connect signal transmission. Generally, to prevent accidental detachment, the socket and plug are connected by a locking mechanism. However, this locking device is prone to detachment in vibrating environments (such as battery connectors in engineering vehicles), causing cable breaks and potentially leading to safety accidents. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a safe connector suitable for high voltage.

[0004] The objective of this utility model is achieved through the following technical solution: An electrical connector includes a socket and a plug. The socket includes a socket housing and a male socket terminal, the male socket terminal being fixed within the socket housing by a male terminal fixing plate. The plug includes a plug housing and a female plug terminal, the female plug terminal being fixed within the plug housing by a female terminal fixing plate. The male socket terminal and the female plug terminal are arranged in the same number and position to allow mating. The electrical connector also includes a locking member for securing the socket and plug. The locking member has a locking housing and a locking bracket movably disposed within the locking housing. The locking bracket allows for radial overall movement relative to the socket and plug. The socket housing is fixed to the locking housing by a locking mechanism. The plug housing has a driving part that drives the locking bracket to move radially as a whole during the movement of the plug housing relative to the socket housing. When the socket and plug are inserted into place, the locking bracket resets, and its locking part locks the plug housing to prevent the plug housing from axially moving away from the plug housing. The locking bracket also includes a release part that, when driven, can release and separate the socket and plug.

[0005] Preferably, the locking mechanism is a buckle provided on the socket housing, which engages with the inner wall of the locking housing to lock the two together. The socket housing is also provided with a sealing ring, which also engages with the inner wall of the locking housing to form a seal.

[0006] Preferably, the driving part is the distal outer wall of the plug housing.

[0007] Preferably, the locking part is a locking strip disposed on the inner side of the locking bracket, and a locking groove is provided on the outer wall of the plug housing to cooperate with it. The length of the locking groove is equivalent to the width of the plug housing. The inner side of the locking strip relative to the plug housing is a wedge-shaped surface, and a spring is provided between the locking strip and the locking housing.

[0008] Preferably, the locking bracket is a frame structure, including two legs, the locking strip is disposed between the two legs, and the release part is also disposed between the two legs. The release part is a push plate, the push plate is spaced apart from the locking strip by a certain distance, the socket and plug are inserted into the space enclosed by the two legs, the push plate and the locking strip, and the spring abuts against the ends of the two legs.

[0009] Preferably, the support leg is provided with a guide groove, and a pin is inserted into the locking housing and inserted into the guide groove to form a sliding limit for the locking bracket.

[0010] Preferably, both the male terminal of the socket and the female terminal of the plug include power terminals and signal terminals.

[0011] The beneficial effects of this utility model are mainly reflected in the following aspects: 1. By setting a locking shell and a locking bracket, the electrical connector can only separate the plug and socket under strong external force, which is suitable for environments with strong vibration and continuous vibration, and prevents accidental power outages or signal interruptions. 2. It achieves a firm connection and reliable locking between the plug and socket. Compared with the conventional plug-in connection method, this structure effectively improves the mechanical connection strength and electrical safety performance, and can fundamentally prevent the connection from being broken due to accidental pulling or collisions while the equipment is energized, thereby ensuring the continuous and stable operation of the equipment and eliminating the safety hazards caused by it.

[0013] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0015] like Figures 1 to 4 As shown, this utility model discloses an electrical connector, including a socket and a plug. Similar to existing technologies, the socket includes a socket housing 1 and a male socket terminal 2, the male socket terminal 2 being fixed inside the socket housing 1 by a male terminal fixing plate 3. The plug includes a plug housing 4 and a female plug terminal 5, the female plug terminal 5 being fixed inside the plug housing 4 by a female terminal fixing plate 6. Both the male socket terminal 2 and the female plug terminal 5 include power terminals and signal terminals, and the male socket terminal 2 and the female plug terminal 5 have the same number and positional arrangement to allow them to mate and complete the switching of current and signals.

[0016] The electrical connector of this invention also includes a locking member for securing the socket and plug. The locking member has a locking housing 7 and a locking bracket 8 movably disposed within the locking housing 7, the locking bracket 8 being radially movable relative to the socket and plug.

[0017] Specifically, the socket housing 1 is fixed to the locking housing 7 by a locking mechanism. The locking mechanism is a snap-fit ​​9 on the socket housing 1, which engages with the inner wall of the locking housing 7 to lock the two together. The snap-fit ​​structure is a conventional fixing structure, securing the socket housing 1 and the locking housing 7 together. Generally, the locking housing 7 is also fixed to vehicle equipment. For better waterproofing and dustproofing, the socket housing 1 is also provided with a sealing ring 10, which also engages with the inner wall of the locking housing 7 to form a seal.

[0018] The plug housing 4 has a driving part, which is the distal outer wall of the plug housing 4. During the movement of the plug housing 4 relative to the socket housing 1, the driving part drives the locking bracket 8 to achieve radial overall movement.

[0019] Combination Figure 2 , Figure 3 ,as well as Figures 5-7 As shown, the locking bracket 8 has a frame structure, including two legs 13, and a locking strip 11 spanning between the two legs 13. A release part is also provided between the two legs 13. The release part is a push plate 14. The push plate 14 is spaced apart from the locking strip 11. The socket and plug are inserted into the space enclosed by the two legs 13, the push plate 14, and the locking strip 11. Two springs 16 abut against the ends of the two legs 13 respectively. The other end of the springs 16 abuts against the inner cavity of the locking housing 7.

[0020] The locking strip 11 serves as the locking part of the locking bracket 8. The outer wall of the plug housing 4 is provided with a locking groove 12 that cooperates with the locking strip 11. The length of the locking groove 12 is approximately equal to the width of the plug housing 4. Thus, when the locking strip 11 enters the locking groove 12, its locking force is large and it is not easy to come loose.

[0021] The locking strip 11 has a wedge-shaped surface on its inner side relative to the plug housing 4. For example... Figure 5 As shown, when the plug and socket are initially connected, the male terminal 2 of the socket and the female terminal 5 of the plug begin to contact, but the plug housing 4 and the socket housing 1 are not yet fixed. Figure 6 As shown, the plug housing 4 continues to move toward the socket housing 1, and the distal outer wall of the plug housing 4 begins to contact the wedge-shaped surface, forcing the locking strip 11 to counteract the elastic force of the spring 16 and begin to move. It is evident that the locking bracket 8 undergoes overall movement. Figure 7As shown, when the socket and plug are plugged in, the locking bracket 8 is reset under the action of the spring 16 and its locking strip 11 is engaged in the locking groove 12 of the plug housing 4, thereby locking the plug housing 4 to prevent the plug housing 4 from moving axially away from the plug housing 4.

[0022] When it is necessary to inspect or repair the plug or socket, pressing the button 14 will cause the locking bracket 8 to move as a whole, thereby disengaging the locking strip 11 from the locking groove 12 and releasing the socket and plug. Preferably, in actual use, a protective cover can be fitted over the outside of the button 14 to prevent foreign objects from pressing the button 14.

[0023] In this preferred embodiment, the support leg 13 is provided with a guide groove 15, and a pin 17 is inserted into the guide groove 15 to form a sliding limit for the locking bracket 8.

[0024] This invention, by setting a locking shell and a locking bracket, ensures that the electrical connector can only separate the plug and socket under strong external force, making it suitable for environments with strong and continuous vibration, and preventing accidental power outages or signal interruptions.

[0025] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
