Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a docking structure for an energy storage connector. Background Technology

[0002] A connector is a device that allows the transmission of information or current between two active devices through contact. It is also known as a plug or socket in China and generally refers to electrical connectors. Essentially, it's a device that connects two active devices to transmit current or signals.

[0003] Existing energy storage connectors often suffer from insecure mating between the male and female ends, with the male end prone to wobbling. Therefore, this invention provides a mating structure for an energy storage connector to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a docking structure for an energy storage 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 mating structure for an energy storage connector includes a male connector and a female connector. The female connector is inserted into the left end of the male connector. The male connector includes a first plastic body with contact terminals inside. A cable is inserted into the rear end of the contact terminals. Spring contacts are symmetrically arranged inside the first plastic body corresponding to the contact terminals. A wire sealing ring is provided on the cable. A rear cover is snapped onto the first plastic body via a first protruding snap point. A snap position is provided on the rear cover corresponding to the first protruding snap point. A button is movably connected to the upper end of the first plastic body via a rotating shaft. An interface sealing ring is provided on the first plastic body via an annular groove. The female connector includes a second plastic body with a copper busbar inside. Long and short terminals are provided at the upper and lower ends of the copper busbar via several rivets. The long and short terminals are staggered. Terminal aids are symmetrically arranged inside the second plastic body corresponding to the upper and lower ends of the copper busbar.

[0007] As a further embodiment of this utility model, the contact terminal includes a wire receiving hole, a contact plane, a mounting rib, and a backlash notch. The spring includes a long spring arm and a side spring arm. The two rearward side spring arms on the spring prevent it from retracting when it is inserted into the first plastic body. The wire receiving hole facilitates the riveting of the cable after it is installed. The contact plane is the contact area between the male and female terminals. The mounting rib facilitates its fixing with the mounting groove in the first plastic body. The long spring arm on the spring facilitates its insertion into the backlash notch on the contact terminal.

[0008] As a further embodiment of this utility model, the inner hole and outer wall of the wire sealing ring and the interface sealing ring are provided with several waterproof baffles, and the back cover is provided with an inner platform corresponding to the wire sealing ring. Through the waterproof baffles, when the wire sealing ring is inserted into the cable, the waterproof baffles in the inner hole of the wire sealing ring are compressed, thereby forming a waterproof barrier interface with the cable. When the first plastic body is installed, the waterproof baffles on the outside of the wire sealing ring are compressed and deformed by the first plastic body to form a waterproof barrier interface. When the back cover is installed into the first plastic body, the inner platform of the back cover comes into contact with and is squeezed by the wire sealing ring. When the male head is installed into the female head, the interface sealing ring is compressed, and then forms a waterproof barrier with the interface.

[0009] As a further embodiment of this utility model, a first anti-foolproof key is provided on the inner sidewall of the first plastic body, and a second anti-foolproof key is provided on the upper and lower sidewalls of the insertion port of the second plastic body corresponding to the first anti-foolproof key. The lower end of the first plastic body is provided with several reinforcing ribs, and the second plastic body is provided with reinforcing grooves corresponding to the reinforcing ribs. The button is provided with a snap hole, and the upper end of the second plastic body is provided with a hook corresponding to the snap hole. Through the mutual cooperation of the first and second anti-foolproof key structures, an anti-foolproof key is formed. When the male and female heads are mated, the snap hole on the male head hooks the hook on the female head, and the male and female heads are mated. Through the combined use of the several reinforcing ribs and reinforcing groove structures, the male head can be prevented from shaking after mating.

[0010] As a further embodiment of this utility model, the copper busbar, long terminal, and short terminal are all provided with rivet holes corresponding to the rivets. The copper busbar is provided with nut holes, and nuts are threaded into the nut holes. The terminal auxiliary device is provided with second protruding buckles symmetrically at the front and rear of its upper end. Guide strips are provided at both the front and rear ends of the terminal auxiliary device. By designing the contact arms of the long terminal and the short terminal to be spaced a certain distance apart and staggered, the insertion and extraction force when the connector is inserted into the copper busbar can be reduced, which is beneficial to actual operation. The second protruding buckles are embedded in the groove of the inner side wall of the second plastic body for undercutting, which facilitates the fixing of the copper busbar. The guide strips facilitate the positioning with the guide groove of the second plastic body during installation, which plays a role in preventing mistake-proofing.

[0011] As a further embodiment of this utility model, the equipment housing is fixed to the second plastic body by a number of fixing screws. A sealing ring is provided between the second plastic body and the equipment housing, and a steel ring is fitted on the fixing screw. By installing the sealing ring on the back of the first plastic body, when the product is installed into the equipment housing, the sealing ring is compressed, forming a waterproof barrier at the installation interface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When this utility model is used, the snap hole on the male head hooks onto the hook on the female head, and the male head and female head are engaged. Furthermore, the use of several reinforcing ribs and reinforcing grooves can prevent the male head from shaking after engagement.

[0014] 2. In use, the waterproof baffle strip is set up so that when the wire sealing ring is inserted into the cable, the waterproof baffle strip inside the wire sealing ring is compressed, thus forming a waterproof barrier interface with the cable. When the first plastic body is installed, the waterproof baffle strip on the outside of the wire sealing ring is compressed and deformed by the first plastic body to form a waterproof barrier interface. When the back cover is installed into the first plastic body, the inner platform of the back cover comes into contact with and is squeezed by the wire sealing ring. When the male connector is installed into the female connector, the interface sealing ring is compressed, and then forms a waterproof barrier with the interface. By installing the sealing ring on the back of the first plastic body, when the product is installed into the equipment box, the sealing ring is compressed, forming a waterproof barrier at the installation interface.

[0015] 3. When using this utility model, by designing the contact arms of the long terminal and the short terminal to be spaced a certain distance apart and staggered, the insertion and extraction force when the connector is inserted into the copper busbar can be reduced, which is beneficial to actual operation. The second protruding buckle is embedded into the groove of the inner side wall of the second plastic body to fix the copper busbar. The guide strip is provided to facilitate the positioning with the guide groove of the second plastic body during installation, which plays a role in preventing mistake. Attached Figure Description
