Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, in particular to a replaceable split slot terminal. Background Art

[0002] With the rapid development of the new energy vehicle industry, charging sockets (heads) defined in the GB / T20234.12.3-2015 standard have become widely used in domestic passenger cars and commercial vehicles. These charging sockets require frequent charging operations throughout the life cycle of new energy vehicles. With the continuous advancement of electric vehicle charging technology, charging power is also continuously increasing, placing higher requirements on the performance of charging sockets and their internal components.

[0003] In current charging socket designs, split-slot terminals are widely used due to their excellent conductivity and connection stability. However, as charging sockets are plugged and unplugged more and more frequently, split-slot terminals are prone to deformation. This deformation not only affects the terminal's conductivity but can also weaken or even cause charging failure. Once a split-slot terminal is severely deformed, the traditional solution is to replace the entire charging socket, which undoubtedly increases maintenance costs and wastes resources.

[0004] In existing technology, the split-slot terminals of charging sockets typically adopt an integrated design, meaning the terminals are fixedly connected to the socket body or cable and cannot be replaced separately. This design means that if the split-slot terminals deform, the entire charging socket must be scrapped, which is not only costly but also detrimental to resource conservation and environmental sustainability. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a replaceable split slot terminal to solve the problem that the split slot terminal of the existing charging socket is designed as an integrated whole and cannot be replaced separately.

[0006] The utility model solves the above technical problems with the following technical solutions: A replaceable split slot terminal comprises a tail cable connection seat and a head replaceable terminal;

[0007] The tail portion of the tail cable connection seat is formed with a cable connection portion, and the head portion thereof is provided with an internal thread groove along the axial direction;

[0008] The head of the replaceable terminal is a split groove structure for connecting a plug, and its tail is provided with an external thread adapted to the internal thread groove;

[0009] The head replaceable terminal is threadedly connected to the internal thread groove of the tail cable connecting seat through an external thread.

[0010] On the basis of the above technical solution, the present invention can also be improved as follows.

[0011] Furthermore, the split groove structure reserves a plug accommodating cavity with an outward opening along the axial direction, and a plurality of split grooves surrounding the plug accommodating cavity are opened along the circumferential direction;

[0012] When the plug is inserted into the plug accommodating cavity, the split groove structure is expanded outward along the split groove.

[0013] Furthermore, an arc-shaped guide surface is formed at the entrance of the plug accommodating cavity of the split groove structure.

[0014] Furthermore, a drainage hole communicating with the plug accommodating cavity is provided at the bottom of the split groove structure.

[0015] Furthermore, a sealing ring fixing groove 1 and a sealing ring fixing groove 2 are respectively provided on the outside of the tail cable connecting seat and the head replaceable terminal.

[0016] Furthermore, the cable connecting portion of the head replaceable terminal is formed with a flat ultrasonic welding surface.

[0017] The beneficial effects of the utility model are:

[0018] 1) By adopting a separate design with a rear cable connector and a head-mounted replaceable terminal, this invention effectively solves the existing problem of charging sockets requiring complete replacement of the split-slot terminals after deformation. If the split-slot structure of the head-mounted replaceable terminal becomes deformed due to frequent plugging and unplugging, users can quickly replace the head-mounted replaceable terminal by simply removing the threaded connector, without having to replace the entire charging socket. This design not only reduces maintenance costs, but also improves repair efficiency and reduces resource waste.

[0019] 2) The slot structure of the replaceable terminal head incorporates an arcuate guide surface, drainage holes, and a sealing ring retaining groove (Second sealing ring retaining groove). These features collectively enhance the stability and waterproof performance of the electrical connection. The arcuate guide surface guides the plug for smooth insertion, reducing friction and resistance; the drainage hole promptly drains accumulated moisture from the plug cavity, preventing poor electrical connection or short circuits; and the sealing ring retaining groove, through the installation of a sealing ring, effectively prevents moisture, dust, and other foreign matter from entering the connection. These features enable the present invention to maintain a stable electrical connection even in humid or rainy environments, improving safety and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] The utility model provides the following preferred embodiments

[0026] like Figure 1-2 As shown, a replaceable split slot terminal includes a tail cable connection seat 1 and a head replaceable terminal 2;

[0027] The tail of the tail cable connection seat 1 is formed with a cable connection portion 1.1, and its head is provided with an internal thread groove 1.2 along the axial direction;

[0028] The head of the replaceable head terminal 2 is a split groove structure 2.1 for connecting a plug, and its tail is provided with an external thread 2.2 adapted to the internal thread groove 1.2;

[0029] The head replaceable terminal 2 is threadedly connected to the internal thread groove 1.2 of the tail cable connecting seat 1 through the external thread 2.2.

[0030] Through the split design of the tail cable connecting seat 1 and the head replaceable terminal 2, the tail of the tail cable connecting seat 1 is provided with a cable connecting part 1.1 for connecting the cable, and its head is provided with an internal thread groove 1.2; the head of the head replaceable terminal 2 is designed as a split groove structure 2.1 for connecting the plug, and the tail is configured with an external thread 2.2 that matches the internal thread groove 1.2 of the tail cable connecting seat 1, thereby realizing a threaded connection between the two, making it convenient to quickly replace the head replaceable terminal 2 when the split groove structure 2.1 is deformed.

[0031] As an embodiment, the split groove structure 2.1 reserves a plug accommodating cavity with an outward opening in the axial direction, and has a plurality of split grooves 2.3 surrounding the plug accommodating cavity in the circumferential direction;

[0032] When the plug is inserted into the plug receiving cavity, the split groove structure 2.1 is expanded outward along the split groove 2.3.

[0033] When the plug is inserted into the plug-receiving cavity, these slots 2.3 allow the slot structure 2.1 to elastically expand outward along its circumference, tightly clamping the plug and ensuring a good electrical connection. This design allows the plug to smoothly engage with the slot structure 2.1 during insertion and removal, while ensuring a stable and reliable connection.

[0034] As a supplement, an arc-shaped guide surface 2.4 is formed at the entrance of the plug accommodating cavity of the split groove structure 2.1.

[0035] The function of the curved guide surface 2.4 is to guide the plug smoothly and accurately into the plug receiving cavity, reducing friction and resistance during insertion, thereby improving insertion convenience and efficiency. Furthermore, the curved guide surface 2.4 also protects the plug and the slot structure 2.1 from damage to a certain extent, thereby extending their service life.

[0036] As a supplement, a drainage hole 2.5 communicating with the plug accommodating cavity is further provided at the bottom of the split groove structure 2.1.

[0037] The function of this drainage hole 2.5 is to promptly drain away moisture or humidity that may accumulate in the plug receiving cavity in a humid or rainy environment, thereby preventing poor electrical connection or short circuit problems caused by moisture and improving the electrical performance and safety of the split slot structure 2.1.

[0038] As a supplement, the tail cable connection seat 1 and the head replaceable terminal 2 are respectively provided with a sealing ring fixing groove 1.3 and a sealing ring fixing groove 2.6.

[0039] These sealing ring fixing grooves 1.3 and 2.6 are used to install and fix the sealing ring. When the two are connected by threads, the sealing ring can effectively fill the gap at the connection to prevent moisture, dust and other external impurities from entering, thereby ensuring the stability and reliability of the electrical connection.

[0040] As an embodiment, the cable connecting portion 1.1 of the head replaceable terminal 2 is formed with a flat ultrasonic welding surface.

[0041] Ultrasonic welding technology uses high-frequency vibrations to generate energy, tightly fusing the cable end to the flat ultrasonic welding surface. The flat shape of the ultrasonic welding surface provides a larger contact area and more uniform welding pressure, ensuring a strong and reliable electrical connection between the cable and the connector.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
