Description

Technical Field

[0001] The utility model relates to the field of high-voltage terminals, in particular to a claw-type high-voltage terminal with two ends for a new energy storage battery. Background Art

[0002] The existing technologies of claw-type high-voltage terminals at both ends for new energy batteries mainly involve the design, safety protection, and contact structure of high-voltage connectors. Claw-type high-voltage terminals at both ends for new energy batteries are mainly used to ensure the high-voltage interconnection system of the whole vehicle, that is, to build a bridge where the internal circuit is blocked or isolated so that the current can flow. High-voltage connectors are generally composed of three parts: shell, seal and other auxiliary structures, insulating parts, and conductive contacts. The functions of connection and conduction can be achieved by plugging and cooperating between the plug sheath and the socket sheath. High-voltage connectors are mainly used in high-voltage and high-current circuits of new energy vehicles, and work simultaneously with conductive cables to transmit the energy of the battery pack to various components of the whole vehicle system through different electrical circuits, such as battery packs, motor controllers, DCDC converters, chargers and other body power units.

[0003] Although significant progress has been made in the existing technology of claw-type high-voltage terminals for new energy batteries, there are still some technical defects. Due to vehicle vibration, plug eccentricity, metal deformation, foreign body interference and other reasons, the high-voltage connector contacts may have poor contact and increased contact resistance, which will cause severe heating when a large current passes through, and even cause a fire. With the increase of use time, wear may occur between the contacts, resulting in a decrease in contact area, an increase in contact resistance, and affecting the performance of the connector. Mechanical connection failure may manifest itself in a variety of failure modes such as welding, crimping, installation and stress state, which are inseparable from the process and use process. During use, due to external factors such as vibration and impact, the claws or other parts of the connector may become loose or broken, resulting in mechanical connection failure. Failure or damage of the high-voltage terminal may require maintenance and replacement. However, due to the particularity and complexity of the high-voltage terminal, maintenance and replacement may be difficult and require professional technicians and equipment.

[0004] Therefore, a claw-type high-voltage terminal with two ends for new energy batteries is designed, which has the advantages of firm installation, simple installation, convenient maintenance, simple mechanical structure and stable electrical connection. Utility Model Content

[0005] The present application provides a two-end claw-type high-voltage terminal for a new energy battery, which adopts the following technical solution:

[0006] A claw-type high-voltage terminal for a new energy storage battery at both ends. The high-voltage terminal comprises a claw structure and a steel sleeve. The claw structure is made of stacked steel plates. A plurality of high claws and low claws are arranged at the front end of the claw structure. The high claws and the low claws are arranged staggered with each other. The high claws and the low claws are arranged in a mirror image up and down. A total of 16 high claws and low claws are arranged up and down. Grooves are arranged on the side surface of the claw structure. The grooves are arranged correspondingly up and down. The steel sleeve is rectangular in shape as a whole, with openings at both ends. Two fixing plates are arranged on the side of the steel sleeve. The fixing plates are inclined to the steel sleeve at a certain angle, and square protrusions are arranged on the sides of the fixing plates.

[0007] Optionally, springs corresponding to the high claws and the low claws on the claw structure are staggered at the upper and lower positions of the steel sleeve opening.

[0008] Optionally, there is a gap between the upper and lower layers of high clamping jaws and low clamping jaws.

[0009] Optionally, the rear end of the claw structure is a stacked steel plate, circular holes are provided on the steel plate, and the stacked steel plates have rounded arc treatments.

[0010] Optionally, both the high clamping jaw and the low clamping jaw are elastic structures.

[0011] Compared with the prior art, the utility model has the beneficial effect that the mutual limitation between the groove and the fixing plate can ensure that the steel sleeve and the spring are in the correct position after assembly without skewing. At the same time, the spring of the steel sleeve plays a supporting role at each claw, which can ensure the stable operation of the high-voltage terminal and the stability of the electrical connection when the car vibrates violently. The claw structure is an elastic contact setting at both ends, which can ensure the stable operation of the high-voltage terminal. A total of 16 claw structures make the high-voltage terminal more stable in connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The embodiment of the utility model provides a claw-type high-voltage terminal with two ends for a new energy storage battery.

[0025] Example: Figure 1-7 As shown, a claw-type high-voltage terminal at both ends for a new energy storage battery, the high-voltage terminal includes a claw structure and a steel sleeve 3, the claw structure is made by stacking a steel plate 6, and a plurality of high claws 1 and low claws 2 are arranged at the front end of the claw structure, the high claws 1 and the low claws 2 are arranged staggered with each other, and the high claws 1 and the low claws 2 are arranged in a mirror image up and down, and a total of 16 high claws 1 and low claws 2 are arranged up and down. There is a gap in the middle of the upper and lower layers of high claws 1 and low claws 2, and the rear end of the claw structure is stacked with a steel plate 6, and a circular hole is arranged on the steel plate 6, and the overlapped part of the steel plate 6 is rounded. A groove 7 is arranged on the side surface of the claw structure, and the groove 7 is arranged correspondingly up and down. Both the high claw 1 and the low claw 2 are elastic structures.

[0026] The steel sleeve 3 is rectangular in shape as a whole, with openings at both ends. Two fixing plates 4 are arranged on the side of the steel sleeve 3. The fixing plates 4 are inclined at a certain angle to the steel sleeve 3. Square protrusions are arranged on the edges of the fixing plates 4. The opening of the steel sleeve 3 is staggered with spring leaves 5 corresponding to the high claw 1 and the low claw 2 on the claw structure.

[0027] Working principle: The claw structure is set into the rear end opening of the steel sleeve 3. At this time, the sides of the steel sleeve 3 are in contact with the sides of the claw structure. The steel sleeve 3 slides along the sides of the claw structure. At this time, the fixing plate 4 protruding inward on the side of the steel sleeve 3 is expanded and slid outward by the action of the two sides of the claw structure. When the fixing plate 4 on the steel sleeve 3 slides to the groove 7 on the claw structure, the fixing plate 4 shrinks into the groove 7. At this time, the protruding block on the fixing plate 4 is stuck in the groove 7 to play a positioning role. At this time, the spring 5 on the steel sleeve 3 is in contact and fastened with the high claw 1 and the low claw 2 on the claw structure. The steel sleeve 3 is set on the claw structure to achieve the installation and fixation of the entire high-voltage terminal. The mutual limit between the groove 7 and the fixing plate 4 can ensure that the steel sleeve 3 and the spring 5 are in the correct position after assembly, and there will be no skew. At the same time, the spring 5 of the steel sleeve 3 plays a supporting role at each claw, which can ensure the stable operation of the high-voltage terminal and the stability of the electrical connection when the car vibrates violently. The claw structure is set with elastic contact at both ends, which can ensure the stable operation of the high-voltage terminal.
