Description

Technical Field

[0001] The present invention relates to the technical field of electric connectors, and in particular to an electric connector for new energy vehicles. Background Art

[0002] Automotive electrical connectors consist of fixed ends and free ends, also known as sockets and plugs. In order to facilitate the effective connection between the car's central control terminal and other internal components and facilitate subsequent maintenance, electrical connectors play a vital role in the layout of the car's internal wiring harness.

[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 control of the battery module needs to be more stringent. 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 car body due to vibration 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 inside the electrical connector, which will accelerate the oxidation and corrosion of the worn contact surface, and at the same time affect the firmness of the connection of the electrical connector.

[0049] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0050] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0051] An electrical connector for new energy vehicles provided by some embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1:

[0052] Combine Figures 1-10 As shown, the present invention provides an electrical connector for new energy vehicles, including a female socket assembly 100, a stabilization mechanism 500 arranged on the female socket assembly 100, a male socket mechanism 200 arranged on the female socket assembly 100, an anti-fretting wear mechanism 400 arranged outside the male socket mechanism 200, and a battery harness 300 arranged on the male socket mechanism 200. The female socket assembly 100 is pre-loaded on the connector of the battery module in the new energy vehicle and provides a stable pressure-resistant platform for the stabilization mechanism 500. The male socket mechanism 200 is used to perform anti-fretting assembly on the female socket assembly 100, the battery harness 300 is used to electrically connect the male socket mechanism 200, the anti-fretting wear mechanism 400 is used to provide anti-corrosion protection for the male socket mechanism 200, and the stabilization mechanism 500 is used to provide pressure-resistant support for the male socket mechanism 200 and the electrically connected battery harness 300.

[0053] The female socket assembly 100 includes a socket body 110 pre-welded on the battery module connector, and a plurality of positioning notches 120 are evenly distributed on the contact surface of the socket body 110;

[0054] Three anti-slip grooves 130 are provided on the insulating surface of the socket body 110;

[0055] The male socket mechanism 200 includes a conductive cover 250, a branching adapter 230 disposed on top of the conductive cover 250, and three poles 240 are disposed on three ends of the branching adapter 230, and the outer ends of the poles 240 are connected to one end of the battery harness 300;

[0056] The branch adapter 230 is provided with an insulating cover 210 on the outside, and a constant pressure stretching traction component 220 is provided inside the insulating cover 210;

[0057] The battery harness 300 is used to electrically connect the pole 240;

[0058] The anti-fretting mechanism 400 includes a reinforced outer cylinder 410 disposed outside the conductive cover 250 , an inner pad 420 is disposed in a groove inside the reinforced outer cylinder 410 , and two locking members 430 are installed on the inner side of the inner pad 420 ;

[0059] The number of the locking members 430 is three, and the three groups of locking members 430 are used to perform low-speed micro-locking on the female socket assembly 100;

[0060] The locking member 430 is composed of an insulating rod and a rectangular conductive pad, and the inner end of the rectangular conductive pad is provided with an arc-shaped groove groove adapted to be snap-fitted into the positioning notch 120;

[0061] The stabilization mechanism 500 includes an anti-pull component 510;

[0062] The anti-pull assembly 510 includes a sleeve 511 , a second shaft 512 is disposed in the sleeve 511 , a buckle 513 is movably mounted on the second shaft 512 , and a spring 514 is disposed between the sleeve 511 and the buckle 513 ;

[0063] Three chucks 520 are evenly distributed on the side of the sleeve 511. Three bases 530 are set on the top of the sleeve 511. Angle adjustment screws 580 are set in the bases 530. A pad 590 is movably installed on the outside of the angle adjustment screws 580.

[0064] A cantilever 540 is movably mounted on the chuck 520 , and a socket is provided at the bottom of the cantilever 540 , into which an angle adjustment screw 580 is adapted to pass;

[0065] A third shaft 550 is provided at the top end of the cantilever 540 . Two anti-breakage housings 560 are installed on the third shaft 550 , and two fourth shafts 570 are installed inside the two anti-breakage housings 560 .

[0066] Since the battery modules in new energy vehicles need to be assembled using electrical connectors, conventional connections require bolts or straps to directly fix the battery electrical connectors to the battery connectors. As the vehicle runs for a long time, the vibration fluctuations transmitted by the vehicle body will radiate to the battery module. Eventually, the battery harness will vibrate under the interference of the vibration waves. At this time, the battery harness will directly pull on the electrical connector and the battery connector.

[0067] 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 after wear will change, and a certain gap will appear, which will cause corrosive media to penetrate the contact surface. In severe cases, it will cause insufficient voltage to be transmitted. At the same time, increased wear of the contact surface will cause further failures.

[0068] The device welds the socket body 110 to 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 is symmetrical with the positioning notch 120, the advancing screw 224 can be manually adjusted to rotate clockwise. At this time, the first shaft 222, which is now assisted, will simultaneously pull the three outer frames 223. At this time, the three pressure-bearing vertical plates 470 can cooperate with the three clips 460 to squeeze the three inner pads 420. The locking piece 430 provided on the inner pad 420 can be inserted through the limiting hole 260 and effectively snapped into the positioning notch 120. At this time, the socket body 110 and the conductive cover 250 are fixed, thereby preventing the problem of wear of the contact surface caused by vibration wave radiation.

[0069] In addition, the traditional single connector is set as a three-connector pole 240. 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 with different assembly methods, and the stabilization mechanism 500 fixed on the socket body 110 as a whole can provide effective and stable support force for one or three poles 240 selectively connected to the battery harness 300, thereby effectively avoiding the problem of micro-wear and post-wear corrosion of the contact structure caused by vibration radiation of the battery harness 300. Example 2:

[0070] Combine Figure 6-Figure 9 As shown, based on the embodiment 1, a cylindrical hole is opened inside the insulating cover 210, and a partition is provided in the cylindrical hole, and a screw sleeve 270 is movably installed in the middle of the partition;

[0071] Three arc-shaped slideways are formed inside the insulating cover 210 .

[0072] Preferably, as the propulsion screw 224 rotates clockwise or counterclockwise, the first shaft 222 that is propelled 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 in the lifting process, thereby ensuring the stable contraction of the three pressure-bearing vertical plates 470.

[0073] A propulsion screw 224 is installed in the screw sleeve 270, and a booster disc 221 is movably installed on the propulsion screw 224. The booster disc 221 has three notches on its side, and a first shaft 222 is provided in the three notches. An outer frame 223 is movably installed on the first shaft 222.

[0074] The three outer frames 223 are adapted to penetrate into the three curved slideways;

[0075] 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;

[0076] 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 .

[0077] Preferably, when the three groups of locking members 430 are pressurized by the pressure-bearing vertical plate 470 and the clip 460 and extend into 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. Example 3:

[0078] Combine Figure 7-10 As shown, based on 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. Two symmetrically distributed column heads are provided 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.

[0079] 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. At this time, 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.

[0080] A plug 480 is installed on the inner side of the top of the pressure-bearing vertical plate 470. A horizontal clip 460 is set 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. An internal compression spring 440 and an external compression spring 450 are respectively set on both sides of the inner pad 420.

[0081] 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 set on the stud and fixed with a nut;

[0082] The plug 480 is made of silicone material.

[0083] Preferably, the built-in compression spring 440 provided on the locking member 430 and the external compression spring 450 provided 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 of 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. Example 4:

[0084] Combine 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 end of the insulating cover 210 are adapted to be inserted into the three slots at the top end of the reinforced outer cylinder 410.

[0085] Preferably, the insulating cover 210 can provide pressure protection for the branch adapter 230 to reduce the wear and tear of the battery harness 300 after connecting to the pole 240, while preventing the static electricity in the harness from interfering with the voltage input of the structure.

[0086] The pad 590 is made of stainless steel, and the inner end of the pad 590 is provided with an inclined surface adapted to fit the cantilever 540;

[0087] The exterior of the cushion 590 is provided with a rubber outer layer.

[0088] 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 one-way support force to the pole 240 after it has flipped over. At this time, the two anti-breakage shells 560 clamped on the pole 240 can obtain compressive support from the cantilever 540 under pressure.

[0089] Working principle and usage 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 reliability. Since the wiring harnesses arranged in the car are relatively dense, the application volume of electrical connectors is also large;

[0090] 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.

[0091] However, battery electrical connectors still have certain defects in the process of transmitting current. 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 the connector and the battery module to have micro-plugging and unplugging. As the connector contact surface wears and its geometric shape changes, 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 interruption during operation.

[0092] 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 a 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 gaskets.

[0093] During use, the socket body 110 and the battery module connector need to be welded in advance. Then, the socket 511 is inserted into the annular groove at the top of the socket body 110. The three angle adjustment screws 580 are adjusted and rotated counterclockwise. At this time, the three cantilevers 540 can be turned sideways along the reinforced outer cylinder 410 as the axis. The four buckles 513 evenly distributed on the socket 511 can be clamped and fixed to the four anti-slip grooves 130 provided on the outer wall of the pre-assembled socket body 110.

[0094] 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 adjust the hexagonal end of the push screw 224 until the push screw 224 rotates clockwise. At this time, the first shaft 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 pieces 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 insert of the locking piece 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 plugged in to obtain anti-micro-motion protection;

[0095] 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. Depending on whether one or three poles 240 are connected to a battery harness 300, the two evenly distributed and combined anti-break shells 560 can center and fix the one or three poles 240 connected to the battery harness 300. Then adjust the angle adjustment screw 580 and rotate it clockwise. At this time, the pad 590 that is indirectly pressured can apply an extrusion force to the root of the cantilever 540 until the cantilever 540 provides effective and stable support force for the two combined anti-break shells 560. At this time, the battery harness 300 set on one or three poles 240 can be protected against abnormal pulling after connection to avoid the battery harness 300 causing pressure loss to the above-mentioned connector structure due to excessive vibration amplitude.

[0096] 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 invention, and that the scope of the invention is defined by the claims and their equivalents.
