Among them, a linear energy storage connector is one of the common electrical connectors, which includes a board-end socket fixed on the device housing and a line-end plug that is plugged into the board-end socket. After the line-end plug is plugged into the board-end socket, an electrical connection can be achieved. For example, in the field of electric vehicles, this type of energy storage connector is often used to charge the car.

[0003] However, in the prior art, most energy storage connectors have the following problems:

[0004] 1. The terminals and shell of the socket are assembled. There is a gap between the assembled terminals and the shell. After the socket is installed on the box, it cannot meet the airtight requirements of the box.

[0005] 2. The sealing body at the end of the plug is sealed by shrinking the sealing body with a nut. This method requires an extra set of plastic molds and an additional process of assembling the plastic shell and the sealing body, which increases the cost of the product.

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-6As shown, an energy storage connector includes a plug body 7 and a socket body 3 that are plugged into each other, and a first snap-fit ​​structure that enables the plug body 7 and the socket body 1 to be connected and fixed is provided at the connection between the plug body 7 and the socket body 1, and a second snap-fit ​​structure that enables the plug body 7 and the socket body 1 to be detachably connected and fixed is provided.

[0031] The present invention proposes an energy storage connector, which is provided with a plug body 7, a socket body 3, a first snap-on structure, and a second snap-on structure. By providing the first snap-on structure and the second snap-on structure at the connection between the plug body 7 and the socket body 1, a secondary lock structure is provided for the plug-in connection between the plug and the socket, so that the energy storage connector is safer during use. The present invention has a simple and compact structure and strong practicality.

[0032] Specifically, as shown in the figure, the plug body 7 is eccentrically provided with an electric plug connector 71 and a wire end connector 72, and the plug body 7 is provided with an installation space for the electric plug connector 71 to be installed and extended outward, and the first buckle structure includes a buckle sleeve 11 fixedly arranged on the inner wall of the installation space, and a plug-in and pull-out space cooperating with the socket body 3 is formed between the inner wall of the buckle sleeve 11 and the electric plug connector 71, and the inner wall of the buckle sleeve 11 is provided with a plurality of buckle blocks 111 cooperating with the socket body 3 to form a buckle. The socket body 3 includes a male terminal 1 and a ferrule 31 for installing the male terminal 1, and an upward opening is formed on the upper part of the ferrule 31, and one end of the male terminal 1 extending into the ferrule 31 is arranged in the opening, and a bayonet 33 is arranged on the ferrule 31, and the ferrule 31 is inserted into the plug-in and pull-out space, and the male terminal 1 is electrically connected to the electric plug connector 71, and the bayonet 33 cooperates with the buckle block 111 to form a buckle, forming the first buckle structure.

[0033] During installation, the plug body 7 is inserted into the socket body 3. During the insertion process, the electrical plug connector 71 on the plug body 7 is aligned with the clamping sleeve 31 for insertion. During the insertion process, the reverse buckle sleeve 11 and the bayonet 33 are provided. The reverse buckle sleeve 11 and the bayonet 33 are clamped and fixed, so that the plug body 7 is electrically connected to the socket body 3 through the male terminal 1, thereby forming a first clamping structure.

[0034] Specifically, as shown in the figure, a mounting plate 32 is provided on the ferrule 31, and a waterproof gasket 2 similar in shape to the mounting plate 32 is provided on the mounting side of the mounting plate 32, and the male terminal 1 and the ferrule 31 are an integral injection-molded structure. During installation, the socket body 3 can be fixed to the box body by M4 screws by correspondingly providing mounting holes on the mounting plate 31 and the waterproof gasket 2, and the socket body 3 has an IP67 waterproof function. By providing the male terminal 1 and the ferrule 31 as an integral injection-molded structure, the socket is installed on the box body with a separate airtight function, and the socket has the function of preventing moisture and dust from entering the box body when it is not plugged into the plug, thereby protecting the internal components of the box body.

[0035] Specifically, as shown in the figure, the end of the male terminal 1 located in the sleeve 31 is fixedly connected with an anti-tentacle cap 4 to prevent human hand contact and leakage. The male terminal 1 and the anti-tentacle cap 4 are snap-fitted so that the anti-tentacle cap is not easy to fall off the male terminal, thereby allowing the socket to have an anti-tentacle function.

[0036] Specifically, as shown in the figure, the lower end of the electrical plug connector 71 is sleeved with a waterproof ring 5 for waterproofing. When the electrical plug connector 71 is inserted into the ferrule 31, the outer periphery of the waterproof ring 5 contacts the inner wall of the ferrule 31. The purpose of assembling the plug body 7 and the waterproof ring 5 is to make the connector have IP67 waterproof function after the plug and the socket are plugged together.

[0037] Specifically, as shown in the figure, the side of the plug body 7 is provided with a plug-in port connected to the installation space, and the plug-in port is provided with a clamping member 6 that can be plugged in and out to form the second buckle structure. When the clamping member 6 is inserted, the first buckle structure is locked, and the plug body 7 and the socket body 3 are locked in an undetachable state. When the clamping member 6 is pulled out, the first buckle structure is unlocked, and the plug body 7 and the socket body 3 are unlocked to a detachable state. The clamping member 6 includes an operating end 61 and a clamping end 61 for plugging and unplugging in the plug-in port. The clamping end 61 is an arc-shaped plate-like structure. When the clamping end 61 is inserted into the plug-in port, the clamping end 61 blocks the upward movement of the clamping sleeve 31 to form the second buckle structure. The inverted sleeve 11 is provided with a notch 112 that allows the clamping end 61 to extend.

[0038] When in use, by setting the clamping piece 6, before inserting the plug body 7, first push the clamping piece 6 inward from the plug-in port, the clamping end 61 first forms a blocking effect, and then insert the plug body 7 into the socket body 3, and use the reverse buckle sleeve 11 and the bayonet 33 to form a clamping fixation, so that the plug body 7 is electrically connected to the socket body 3 through the male terminal 1, thereby forming a first clamping structure. At the same time, the lower end surface of the clamping end 61 conflicts with the upper end of the clamping sleeve 31, that is, The plug body 7 cannot be further inserted downward, thereby forming a second snap-on structure, which increases safety. When the plug body 7 needs to be removed, the clamping piece 6 is pulled out, so that the plug body 7 can be moved and continued to be inserted downward, so that the buckle block 111 is disengaged from the bayonet 33. After disengagement, the plug body is slightly rotated to cause the buckle block 111 to be misaligned with the buckle 33, and the plug body 7 can be removed in the opposite direction. The simple and compact structure makes the connector safer during use, and the snap-on structure can be repeatedly disassembled and assembled, which is beneficial to later maintenance.

[0039] Specifically, as shown in the figure, the cable end connector 72 is provided with a cable gland 10, a sealing body 9, and an O-ring 8. The sealing body 9 is sleeved on the incoming line, the cable gland 10 is sleeved outside the sealing body 9 and is threadedly connected with the cable end connector 72, the O-ring 8 increases the waterproof effect, and the sealing body 9 is provided with a sealing rib 9 that fits tightly with the inner wall of the cable gland 10. The cable gland 10, the sealing body 9, the O-ring 8 and the plug body 7 have an IP67 waterproof function after assembly, and the sealing body is sealed with three ribs, thereby reducing one plastic part and one process, and reducing product costs.

[0040] Specifically, as shown in the figure, the number of the undercut blocks 111 is the same as the number of the bayonet holes 33. In this embodiment, the number of the undercut blocks 111 and the number of the bayonet holes 33 are both 6.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
