[0002] The battery pack of new energy vehicles is usually installed under the vehicle. Usually, the output interface of the power battery needs to install a wiring harness connector and then supply power to the vehicle's motor and other electrical appliances through cables. Usually, the wiring harness connector is directly exposed under the vehicle.

[0003] The existing patent (Announcement No.: CN209709246U) discloses a new energy vehicle connector, including a socket and a plug, wherein a pin is provided in the socket, and a female terminal is provided in the plug; and a locking mechanism for locking the socket and the plug, wherein a transfer terminal connected at a right angle to the female terminal is provided in the plug, and the transfer terminal is connected to the female terminal in a threaded manner, and a jack plastic part for assembling the female terminal and a terminal plastic part for assembling the transfer terminal are provided in the plug, and one end of the female terminal is a jack for inserting the pin, and the other end is a threaded connection end with a threaded outer wall, and a screw hole for the threaded connection end to penetrate and form a threaded match is provided on the transfer terminal, and an annular boss with a locking hole is provided in the terminal plastic part, and the inner diameter of the locking hole is smaller than the outer diameter of the thread of the threaded connection end, and the threaded connection end extends into the locking hole after threadedly matching with the screw hole. The utility model has a reasonable structure and can enhance the connection stability between the female terminal and the transfer terminal to ensure the stability of the connection performance of the electrical connector.

[0004] In the process of implementing the solution, the inventor found that when the output cable of the power battery is connected under the car, the dust raised during the driving of the vehicle or the mud and sand adhered during the wading process can easily cause the locking slide to be blocked, which can easily cause the wiring harness connector to be unable to be disassembled and assembled normally during subsequent vehicle maintenance and repair operations.

[0005] 1. Technical problems solved by the utility model:

[0006] The utility model provides a new energy vehicle connector, which solves the technical problem that the locking slideway of the existing wiring harness connector is easily blocked by mud and sand during open installation and is difficult to disassemble and assemble.

[0007] 2. Technical solution:

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a new energy vehicle connector, comprising the following structure:

[0009] The socket has a mounting plate fixedly arranged in the middle of the socket, and fracture protection areas are fixedly arranged on both left and right sides of the mounting plate.

[0010] A telescopic rod, wherein a baffle is clamped at the front of the telescopic rod.

[0011] Furthermore, locking pins are fixedly provided at both left and right ends of the front portion of the socket.

[0012] Furthermore, the telescopic rod includes a guide tube, which is symmetrically arranged on the left and right sides of the middle part of the mounting plate, and the rear ends of the two guide tubes are fixedly connected to the left and right ends of the mounting plate respectively. The middle part of the guide tube is movably sleeved with a guide rod, and the rear end of the guide rod is clamped with a return spring, and the front end of the return spring is clamped with the front part of the inner wall of the guide tube.

[0013] Furthermore, a water retaining groove is fixedly provided on the outer top of the baffle plate, a plurality of diverter plates are fixedly provided on the bottom of the baffle plate, and a water leakage hole is fixedly provided on the bottom of the baffle plate.

[0014] Furthermore, the left and right sides of the baffle extend to the left and right ends of the front side of the mounting plate, the bottom of the baffle extends to the bottom of the front side of the mounting plate, and an assembly cavity is fixedly provided in the middle of the baffle.

[0015] Furthermore, a plug is clamped at the front of the socket, the plug cooperates with the assembly cavity, a rotating pin is movably connected to the outer side of the plug, and locking slides are fixedly provided at both left and right ends of the rotating pin, which cooperate with the locking pin.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0018] The utility model provides a new energy vehicle connector. When the baffle is impacted by the outside, the guide rod is driven to move toward the rear end of the guide tube, and the reset spring is stretched to prevent the external water flow from directly impacting the socket and the plug. The water retaining groove design of the baffle prevents the water flow from directly flowing into the inner side of the baffle along the outer surface of the baffle when the water flow impacts the surface of the baffle. The baffle provides a semi-open shielding treatment for the socket and the plug, and prevents impurities such as mud and sand on the road from directly impacting the socket and the plug during the vehicle formation process, resulting in excessive mud and sand adhering to the locking slideway to affect the normal opening and closing treatment of the rotating pin outside the locking pin;

[0019] The utility model provides a new energy vehicle connector. When the impact force on the baffle exceeds the bearing capacity of the supporting guide structure composed of the mounting plate and the guide tube, the baffle drives the guide rod to move toward the rear end of the guide tube. At this time, the fracture protection zone structure design on the mounting plate causes the mounting plate structure in the fracture protection zone to crack or directly break. At this time, the baffle and the guide tube and other structures will fall from the front of the plug. During the subsequent vehicle inspection and maintenance operations, if the maintenance personnel find that the baffle and other structures have fallen or cracks have appeared in the fracture protection zone, they can use this to evaluate whether the connectors of the socket and the plug need to be replaced.

[0020] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] See attached Figure 1-6 The utility model provides a new energy vehicle connector, including the following structure:

[0039] The socket 1 has a mounting plate 2 fixedly disposed in the middle of the socket 1 , and fracture protection areas 21 fixedly disposed on both left and right sides of the mounting plate 2 .

[0040] The telescopic rod 3 has a baffle 4 clamped on the front of the telescopic rod 3 .

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, locking pins 11 are fixedly disposed at both left and right ends of the front portion of the socket 1 .

[0042] The locking pin 11 provided on the socket 1 cooperates with the rotating pin 7 to complete the anti-drop protection of the socket 1 and the plug 6, and its structural design is a commonly used design method in automobile wiring harness connectors.

[0043] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the telescopic rod 3 includes a guide tube 31, which is symmetrically arranged about the middle of the mounting plate 2. The rear ends of the two guide tubes 31 are fixedly connected to the left and right ends of the mounting plate 2 respectively. A guide rod 32 is movably sleeved in the middle of the guide tube 31, and a return spring 33 is clamped at the rear end of the guide rod 32. The front end of the return spring 33 is clamped with the front part of the inner wall of the guide tube 31.

[0044] The return spring 33 pushes the guide rod 32 forward in the middle of the guide tube 31 , pushing the baffle 4 toward the front of the socket 1 .

[0045] In this embodiment, Figure 1 , Figure 2 and Figure 6 As shown, a water retaining groove 41 is fixedly provided on the outer top of the baffle plate 4 , a plurality of diverter plates 5 are fixedly provided on the bottom of the baffle plate 4 , and a water leakage hole 42 is fixedly provided on the bottom of the baffle plate 4 .

[0046] When this product is installed on the bottom of the vehicle for use, the baffle 4 needs to face the front of the vehicle. At this time, the water flow brought by the bottom of the chassis during the vehicle's forward movement impacts the surface of the baffle 4. The baffle 4 is impacted by the external impact and drives the guide rod 32 to move toward the rear end of the guide tube 31. The return spring 33 is stretched to prevent the external water flow from directly impacting the socket 1 and the plug 6.

[0047] The water retaining groove 41 of the baffle 4 is designed to prevent the water from flowing directly along the outer surface of the baffle 4 into the inner side of the baffle 4 when the water flows on the surface of the baffle 4. The water leakage hole 42 is designed to prevent water from accumulating inside the baffle 4 and affecting the connection between the socket 1 and the plug 6.

[0048] The design of the diverter plate 5 diverts and guides the water flow impacting the outside of the baffle 4.

[0049] In this embodiment, Figure 1 , Figure 2 and Figure 6 As shown, the left and right sides of the baffle plate 4 extend to the left and right ends of the front side of the mounting plate 2, the bottom of the baffle plate 4 extends to the front bottom of the mounting plate 2, and an assembly cavity is fixedly provided in the middle of the baffle plate 4.

[0050] The baffle 4 provides a semi-open shielding treatment for the socket 1 and the plug 6 to prevent impurities such as mud and sand on the road from directly impacting the socket 1 and the plug 6 during the vehicle formation process, causing excessive mud and sand to adhere to the locking slide 71 and affecting the normal opening and closing of the rotating pin 7 outside the locking pin 11.

[0051] When the impact force received by the baffle 4 exceeds the bearing capacity of the supporting guide structure composed of the mounting plate 2 and the guide tube 31, the baffle 4 drives the guide rod 32 to move toward the rear end of the guide tube 31. At this time, the fracture protection zone 21 on the mounting plate 2 is designed, and the mounting plate 2 structure of the fracture protection zone 21 is cracked or directly broken. At this time, the baffle 4, the guide tube 31 and other structures will fall from the front of the plug 6. During the subsequent vehicle inspection and maintenance operations, if the maintenance personnel find that the baffle 4 and other structures have fallen or cracks have appeared in the fracture protection zone 21, etc., they can use this to evaluate whether the connectors of the socket 1 and the plug 6 need to be replaced.

[0052] In this embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a plug 6 is clamped at the front of the socket 1, and the plug 6 cooperates with the assembly cavity. A rotating pin 7 is movably connected to the outer side of the plug 6, and locking slides 71 are fixed at both left and right ends of the rotating pin 7, and the locking slides 71 cooperate with the locking pin 11.

[0053] The outside of the socket 1 is provided with a rotating pin 7, and the structural arrangement of the rotating pin 7 and the locking slideway 71 is a conventional structural design of this product.

[0054] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
