[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and 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. Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1: Refer to Figures 1-5A battery swapping connector with replaceable terminal structure includes a front base plate 1, a rear base plate 12 fixedly connected to the lower part of the front base plate 1 by bolts, and a rear terminal assembly 4 fixedly connected to the rear base plate 12. A front terminal assembly 3 is inserted into the rear terminal assembly 4, and the front terminal assembly 3 can be replaced independently. A limiting pressure plate 2 is installed on the front base plate 1 to press and fix the front terminal assembly 3. The rear terminal assembly 4 includes a power rear terminal 41, a grounding rear terminal 42, and a low-voltage rear terminal 43. The end of the rear terminal assembly 4 is connected to the vehicle body wiring harness. The front terminal assembly 3 includes a power front terminal 31, a grounding front terminal 32, and a low-voltage front terminal 33. The distribution of the front terminal assembly 3 corresponds to the distribution of the rear terminal assembly 4. A power limiting hole 23 is opened on the limiting pressure plate 2, and the power limiting hole 23 corresponds to the power front terminal 31. Correspondingly, the limiting pressure plate 2 has a grounding limiting hole 24, which corresponds to the position of the grounding front terminal 32. The limiting pressure plate 2 also has a low-voltage limiting hole 25, which corresponds to the position of the low-voltage front terminal 33. The front base plate 1 is fixedly connected to a limiting insertion hole 11, which is used to assist the plug in connecting to the front terminal assembly 3. The limiting pressure plate 2 has multiple fixed through holes 22, and the limiting insertion hole 11 is connected to a locking bolt 21 by thread. The limiting pressure plate 2 is installed on the limiting insertion hole 11 by the locking bolt 21. The front terminal assembly 3 is fixedly connected to a limiting protrusion 34. When the limiting pressure plate 2 is installed, the limiting pressure plate 2 and the limiting insertion hole 11 together clamp and limit the limiting protrusion 34. The front base plate 1 may have positive and negative power markings, and a rubber sealing ring is provided on the side wall of the front base plate 1.

[0029] In this utility model, the front base plate 1 and the rear base plate 12 are connected to the internal circuit of the vehicle body through the rear terminal assembly 4 via a wiring harness. The rear terminal assembly 4 is fixed on the rear base plate 12, and the rear base plate 12 is fixedly connected to the front base plate 1. The front base plate 1 is fixedly connected to the limiting insertion hole 11, and the limiting insertion hole 11 is fixedly connected to the limiting pressure plate 2. After the limiting pressure plate 2 is fixed, it will squeeze the front terminal assembly 3 to be inserted into the rear terminal assembly 4, so that the entire device forms a whole and is fixed at the interface. The difference from the common terminal interface is that there is an additional front terminal assembly 3 and limiting pressure plate 2. The front terminal assembly 3 serves as a transmission transition component between the battery plug and the connector. It can replace the rear terminal assembly 4 to bear the wear and tear between the battery plug and the connector. Even if it is damaged due to wear, the front terminal assembly 3 can be quickly replaced locally. The replacement cost is low, and it is convenient to quickly confirm the damaged location.

[0030] The front terminal assembly 3 includes a power front terminal 31, a ground front terminal 32, and a low-voltage front terminal 33. All connectors are independently configured, which allows the replacement parts to be minimized, thereby reducing replacement costs.

[0031] The bottom of the power front terminal 31, the ground front terminal 32, and the low voltage front terminal 33 are all provided with a limiting protrusion 34 protruding outward. The fixing through hole 22 is used to lock the bolt 21 through the limiting pressure plate 2 and install it on the limiting insertion hole 11. When the limiting pressure plate 2 is installed, it is installed on the limiting insertion hole 11 as the locking bolt 21 rotates. The limiting pressure plate 2 moves down with the locking bolt 21 and is fixed on the limiting insertion hole 11. The power front terminal 31, the ground front terminal 32, and the low voltage front terminal 33 pass out from the power limiting hole 23, the ground limiting hole 24, and the low voltage limiting hole 25, respectively. The limiting protrusion 34 protruding outward at the bottom of the power front terminal 31, the ground front terminal 32, and the low voltage front terminal 33 is pressed down by the limiting pressure plate 2 and moves down together, so that the limiting pressure plate 2 and the limiting insertion hole 11 together clamp and limit the limiting protrusion 34, thereby completing the clamping and fixing of the front terminal assembly 3.

[0032] The limiting pressure plate 2 may have positive and negative power terminals and grounding marks, which facilitates confirmation of the mating hole when installing the front terminal assembly 3. The rubber sealing ring on the side wall of the limiting pressure plate 2 can fill the gap between the limiting pressure plate 2 and the limiting insertion hole 11, preventing liquid from flowing into the rear terminal assembly 4 from the gap and causing damage to the rear terminal assembly 4.

[0033] During installation, the user first connects the rear terminal assembly 4 to the cable inside the vehicle body. Then, the rear base plate 12 with the rear terminal assembly 4 is spliced ​​together with the front base plate 1 and fixed to the vehicle body with bolts. Next, the front terminal assemblies 3 are inserted into the corresponding rear terminal assemblies 4 in sequence, and the limiting pressure plate 2 is put on the front terminal assembly 3 and fixed in the limiting insertion hole 11 with locking bolts 21 to complete the installation. If the front terminal assembly 3 is damaged, simply remove the limiting pressure plate 2 and pull the damaged part from the rear terminal assembly 4 to replace it.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
