[0003] With the rapid development of new energy vehicles today, the battery module is the most widely used electrical connector in new energy vehicles. As the energy supply terminal of new energy vehicles, the electrical connection of the battery module needs to be more strictly controlled. Since the electrical connector on the battery module is also mainly used to transmit voltage and current, as the battery module moves with the car, the vibration waves radiated by the vibration of the car body will radiate to the battery module. With the radiation of the vibration wave, the electrical connector will generate thermal shock during the output or input current, accompanied by the micro-motion phenomenon caused by the vibration. In severe cases, it will cause micro-motion wear on the contact surface of the electrical connector, which will accelerate the oxidation and corrosion of the worn contact surface, and also affect the firmness of the connection of the electrical connector.

Two anti-breaking shells 560 are installed on the third shaft 550 . Two fourth shafts 570 are installed inside the two anti-breaking shells 560 .

[0026] Since the battery modules in new energy vehicles need to be assembled using electrical connectors, but conventional connections require bolts or straps to directly fix the battery electrical connectors and the battery connectors. As the vehicle runs for a long time, the vibration waves transmitted by the vehicle body will radiate to the battery module, and eventually the battery harness will vibrate under the interference of the vibration waves. At this time, the battery harness will directly pull the electrical connector and the battery connector. Therefore, the contact surfaces of the battery module connector and the electrical connector will experience contact wear and micro-wear. The geometric shape of the contact surface changes after wear, and a certain gap will appear, which will cause corrosive media to penetrate into the contact surface. In severe cases, it will cause insufficient voltage transmission. At the same time, increased contact surface wear will cause further failures.

[0027] The device is welded by welding the socket body 110 and the joint of the battery module. At this time, the exposed contact surface of the socket body 110 can be easily and quickly plugged into the conductive cover 250. When the limiting hole 260 and the positioning notch 120 are symmetrical, the advancing screw 224 can be manually adjusted to rotate clockwise. At this time, the first shaft rod 222 that is boosted will pull the three outer frames 223 at the same time. At this time, the three pressure-bearing vertical plates 470 can cooperate with the three clips 460 to squeeze the three inner pads 420, and the locking piece 430 set on the inner pad 420 can be inserted from the limiting hole 260 and effectively snapped into the positioning notch 120. At this time, the fixed socket body 110 and the conductive cover 250 can avoid the problem of wear of the contact surface caused by vibration wave radiation. In addition, by setting the traditional single-connector pole 240 to a three-connector pole, according to the uniform distribution of different battery modules, the three poles 240 can cooperate with the three battery harnesses 300 to quickly connect batteries of different assembly methods, and the stabilization mechanism 500 fixed on the socket body 110 as a whole can provide effective and stable support for one or three poles 240 selectively connected to the battery harness 300, thereby effectively avoiding the problem of micro-wear of the contact structure caused by vibration radiation of the battery harness 300 and corrosion after wear. Embodiment 2:

[0028] Combination Figure 6-Figure 9 As shown, on the basis of embodiment 1, a cylindrical hole is opened inside the insulating cover 210, and a partition is arranged inside the cylindrical hole, and a screw sleeve 270 is movably installed in the middle of the partition; Three arc-shaped slideways are formed inside the insulating cover 210 .

[0029] Preferably, as the advancement screw 224 rotates clockwise or counterclockwise, the first shaft 222 that is boosted will drive the three outer frames 223 to rise and fall synchronously. At this time, the three arc-shaped slides can provide orderly and stable lifting constraints for the three outer frames 223 during lifting, thereby ensuring the stable contraction of the three pressure-bearing vertical plates 470.

[0030] A propulsion screw 224 is installed in the screw sleeve 270, and a booster disc 221 is movably installed on the propulsion screw 224. Three notches are opened on the side of the booster disc 221, and a first shaft 222 is arranged in the three notches, and an outer frame 223 is movably installed on the first shaft 222; The three outer frames 223 are adapted to penetrate into the three arc-shaped slideways; The conductive cover 250 is made of copper material, and the inner wall of the conductive cover 250 is provided with a plurality of evenly distributed limiting holes 260; The bottom end of the conductive cover 250 is provided with a horn end adapted to fit on the top surface of the socket 511 .

[0031] Preferably, when the three groups of locking members 430 are pressurized by the pressure-bearing vertical plate 470 and the clip 460 and extend toward the interior of the conductive cover 250, the evenly distributed multiple limiting holes 260 can constrain the extended multiple locking members 430 until the locking members 430 fix the positioning slots 120. The centrally clamped socket body 110 can be fitted with the inner wall of the conductive cover 250 at a constant pressure, thereby avoiding uneven pressure on the contact surface between the socket body 110 and the conductive cover 250 and causing geometric wear and bending. Embodiment 3:

[0032] Combination Figure 7-10As shown, on the basis of Example 1, the anti-micro-wear mechanism 400 also includes an internal compression spring 440, an external compression spring 450 and a pressure-bearing vertical plate 470, and two symmetrically distributed column heads are arranged on the inner side of the pressure-bearing vertical plate 470, and the two column heads are adapted to penetrate into the groove of the reinforced outer cylinder 410.

[0033] Preferably, the reinforced outer cylinder 410 can be selected as a solid or hollow structure according to the different assembly environments of the battery modules. In this case, a semiconductor cooling plate can be added to the inner wall of the reinforced outer cylinder 410. In an extremely hot environment, the contact part between the conductive cover 250 and the socket body 110, which are continuously running and generating high temperatures, can be effectively temperature-controlled by the semiconductor cooling plate.

[0034] A plug 480 is installed on the inner side of the top of the pressure-bearing vertical plate 470, a horizontal clip 460 is provided on the top of the pressure-bearing vertical plate 470, and the other end of the clip 460 is connected to the inner pad 420, and the internal compression spring 440 and the external compression spring 450 are respectively provided on both sides of the inner pad 420; The outer end of the top of the pressure-bearing vertical plate 470 is provided with a stud, and the bottom end of the outer frame 223 is provided on the stud and fixed with a nut; The plug 480 is made of silicone material.

[0035] Preferably, the built-in compression spring 440 arranged on the locking piece 430 and the external compression spring 450 arranged on the inner column head of the pressure-bearing vertical plate 470 can provide a central elastic support force for the inner pad 420, and maintain a sufficiently safe gap with the contact surface with the socket body 110 in the initial state. At this time, the rectangular conductive pad can cooperate with the conductive cover 250 to effectively contact the socket body 110, thereby reducing the probability of wear of the socket body 110 and the conductive cover 250, while improving the constancy of the input pressure. Embodiment 4:

[0036] Combination Figure 4-Figure 7 As shown, in the above embodiment, the insulating cover 210 is made of stainless steel, and the surface of the insulating cover 210 is coated with an insulating paint layer, and the three pads at the bottom of the insulating cover 210 are adapted to be inserted into the three notches at the top of the reinforced outer tube 410.

[0037] Preferably, the insulating cover 210 can provide pressure protection for the branch adapter 230 to reduce the wear and tear force of the battery harness 300 after the connection to the pole 240, while preventing the static electricity of the harness from interfering with the pressure transmission of the structure.

[0038] The cushion 590 is made of stainless steel, and the inner end of the cushion 590 is provided with an inclined surface adapted to fit the cantilever 540; The outside of the cushion 590 is provided with a rubber outer layer.

[0039] Preferably, the clockwise or counterclockwise rotation of the angle adjustment screw 580 along the inside of the base 530 can apply an extrusion force to the cushion 590. At this time, the sloped surface at the inner end of the cushion 590 can provide a unidirectional supporting force to the pole 240 after the overturned pole. At this time, the two anti-breakage shells 560 clamped on the pole 240 can obtain compressive support from the cantilever 540 under pressure.

[0040] Working principle and use process of the present invention: In addition to meeting general performance requirements, automotive electrical connectors must also ensure good contact after assembly to improve their working reliability. Since the wiring harnesses arranged in the car are densely packed, the application volume of electrical connectors is also large; With the increasing number of new energy vehicles, more reliable electrical connectors are needed on the battery modules in new energy vehicles to connect the battery modules. However, there are still certain defects in the process of transmitting current in the battery electrical connector. When the car is driving, the battery module and the car body will produce a resonance effect, so the bump amplitude of the car will be transmitted to the battery module. Therefore, excessive vibration amplitude will cause micro-plugging and unplugging of the connector and the battery module. As the contact surface of the connector wears and changes in geometry, the electrical connector will become loose. In severe cases, it will cause insufficient electrical contact pressure of the battery module, which will cause a momentary fault during operation. The device is configured by setting the plug structure of the traditional single-branch connector to a hierarchical and three-head branch adapter 230 and pole 240, and setting a conductive cover 250 at the bottom of the branch adapter 230. At this time, the conductive cover 250 is connected to the three poles 240 through a gasket; When in use, the socket body 110 and the joint of the battery module need to be welded in advance, then the socket 511 is inserted into the annular groove at the top of the socket body 110, and the three angle adjustment screws 580 are adjusted to rotate counterclockwise, at which time the three cantilevers 540 can be turned sideways along the reinforced outer cylinder 410 as the axis, and the four buckles 513 evenly distributed on the socket 511 can be clamped and fixed to the four anti-slip grooves 130 opened on the outer wall of the pre-installed socket body 110; Then, the combined reinforced outer cylinder 410 and the conductive cover 250 are plugged into the socket body 110. At this time, the top of the socket body 110 will be stuck in the inner cavity of the conductive cover 250. Then, the hexagonal end of the top of the push screw 224 is adjusted until the push screw 224 rotates clockwise. At this time, the first shaft rod 222, which is lifted upward by the push screw 224, will simultaneously apply traction to the three outer frames 223. At this time, the three outer frames 223 will simultaneously apply inward contraction pulling force to the three pressure-bearing vertical plates 470 until the pressure-bearing vertical plates 470 apply thrust to the clip 460 and the inner pad 420. At this time, the two locking members 430 installed at the top and bottom of the inner side of the inner pad 420 will extend toward the inside of the limiting hole 260 until the plug-in block of the locking member 430 is effectively stuck in the inner side of the positioning notch 120. At this time, the socket body 110 and the conductive cover 250 can be protected from micro-motion after being plugged in. After the above-mentioned electrical connector structure is fixed, multiple battery harnesses 300 can be selectively selected according to the distribution of the battery modules to connect with the outer ends of the three poles 240. According to whether one or three poles 240 are connected to the battery harness 300, two evenly distributed and combined anti-break shells 560 can be used to center and fix the one or three poles 240 connected to the battery harness 300. Then the angle adjustment screw 580 is adjusted to rotate clockwise. At this time, the cushion 590 that is indirectly pressed can apply an extrusion force to the root of the cantilever 540 until the cantilever 540 provides effective and stable supporting force for the two combined anti-break shells 560. At this time, the battery harness 300 arranged on one or three poles 240 can be protected against abnormal movement and pulling after connection to prevent the battery harness 300 from causing pressure damage to the above-mentioned connector structure due to excessive vibration amplitude.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
