Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-efficiency conductive boost plug and socket assembly. Background Technology

[0002] In the field of connector technology, high-efficiency conductive boost plug and socket assemblies, as key components for achieving circuit conduction and voltage boosting functions, are widely used in electronic equipment, medical devices, industrial control, and other scenarios requiring stable high-current transmission. The core performance of these devices depends on the reliability of electrical contact when the plug and socket are mated. Poor contact not only leads to decreased transmission efficiency and increased voltage loss, but may also cause safety hazards such as overheating and arcing due to excessive contact resistance. Especially in applications with stringent requirements for power supply stability (such as precision medical equipment and high-voltage electronic systems), these problems may directly affect the operating accuracy of the equipment or even cause malfunctions.

[0003] Currently, the contact structure of existing high-efficiency conductive boost plug and socket assemblies has many shortcomings: First, traditional contact units mostly use a single contact piece or a few contact points, resulting in limited contact area. During insertion and removal or under vibration, problems such as instantaneous disconnection and sudden changes in contact resistance can easily occur, making it difficult to meet the requirements of high-stability transmission. Second, the bending structure of some contact pieces is a progressive arc design, which results in uneven contact pressure distribution when mating with the male terminal. Moreover, after long-term use, pressure decay is easily caused by elastic fatigue, further reducing contact reliability. Third, the mating precision between the contact unit and the male terminal is insufficient, often leading to excessive wear of local contacts due to misalignment, shortening the service life of the device. Fourth, in low-voltage input scenarios (such as old charging piles), it is impossible to efficiently charge high-voltage battery packs. Utility Model Content

[0004] The present invention aims to solve the above-mentioned defects and provide a high-efficiency conductive boost plug and socket assembly.

[0005] In order to overcome the defects in the background technology, the technical solution adopted by this utility model to solve its technical problem is: a high-efficiency conductive boost plug and socket assembly, including a plug mechanism, which has a welding male terminal inside, and the welding male terminal is welded to a cable. The socket mechanism has a mating female terminal inside, which is detachably connected to the plug-in end of the housing assembly, and has a contact unit inside that is connected to the mating female terminal. The contact unit includes two symmetrically distributed contact plates, and multiple openings are formed through the contact plates to form multiple contact pins. The middle area of ​​the contact pins bends abruptly towards the center of the two contact plates, and the welding male terminal is inserted between the two contact plates.

[0006] Further improvements include the plug mechanism comprising a male terminal housing and a male terminal back cover, wherein the wiring terminals of the male terminal housing are detachably connected to the male terminal back cover, which can stably limit the soldering male terminal inside the male terminal housing, and the cable passes through the male terminal back cover axially and connects to the soldering male terminal.

[0007] Further improvements include providing a locking part inside the male terminal housing to prevent the soldered male terminal from retracting.

[0008] Further improvements include the locking part comprising a locking piece disposed within the male terminal housing, wherein a locking arm is formed by peeling off the locking piece and abruptly bending it to one side, and the locking arm is engaged with a locking groove pre-set on the surface of the welding male terminal to limit the axial movement of the welding male terminal.

[0009] Further improvements include the socket mechanism comprising a female terminal housing and a female terminal rear cover, wherein the rear end of the female terminal housing is detachably connected to the female terminal rear cover, thereby stably limiting the mating female terminal inside the female terminal housing, and the front end of the female terminal housing is provided with a socket.

[0010] Further improvements include using copper busbars or aluminum busbars for the welding male terminal and the mating female terminal.

[0011] The beneficial effects of this utility model are as follows: This design adopts a contact unit with a special structure. The double contact plate and multiple contact pins increase the contact points and area with the terminal, avoiding instantaneous disconnection; the sudden bending of the contact pins ensures uniform and lasting contact pressure, reduces poor contact caused by elastic fatigue, and is suitable for high stability requirements; the multiple contact pins, together with the terminal, improve conductivity efficiency, stably transmit the large current after voltage boost, are suitable for high-power equipment, and broaden the application range.

The middle area of ​​the contact pins 502 is abruptly bent towards the center of the two contact plates 501. When the welding male terminal 3 is inserted between the two contact plates 501, the contact pins 502 always remain in contact with the welding male terminal 3.
