Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and particularly to a terminal locking structure for a square battery. Background Technology

[0002] The terminal locking structure of a square battery refers to a structure in a square battery module used to fix and connect the battery terminals to the wire connecting pieces. A square battery module is mainly composed of multiple square batteries arranged in sequence. The positive and negative terminals of the multiple square batteries are led out by the wire connecting pieces through the conductive busbar inside the conductive busbar bracket. Then, the wire connecting pieces are connected to the battery terminals. Conventional wire connecting pieces and battery terminals are often connected by welding or bolts. Welding and bolting are often more complicated and dangerous. Utility Model Content

[0003] The purpose of this invention is to solve the problem that conventional methods of connecting wires and battery terminals in the prior art often involve welding and bolting; however, welding and bolting are often cumbersome and dangerous.

[0004] Therefore, in view of the aforementioned problem, this utility model proposes a terminal locking structure for a square battery, including a conductive busbar support, a conductive busbar inside the conductive busbar support that is connected to the positive and negative terminals of multiple square batteries, wire connecting pieces on both sides of the conductive busbar support, the wire connecting pieces being electrically connected to the wire busbar inside the conductive busbar support, an electrode support connected to one side of the wire connecting piece, a terminal post connected to the bottom of the electrode support, and a quick-connect mechanism on the motor support and the wire connecting pieces.

[0005] Preferably, the quick-connect mechanism includes a limiting groove, with limiting grooves provided on both the left and right sides of the wire connecting piece.

[0006] Preferably, the quick-connect mechanism further includes a sliding plate, which is slidably connected to the upper part of the electrode support. The top of the sliding plate is provided with multiple protrusions to increase friction, and the lower part of the sliding plate has two symmetrical inclined grooves. An electrode post is also fixedly installed at the bottom of the electrode support.

[0007] Preferably, the electrode holder also has a slot in the middle for placing an electrical connection piece.

[0008] Preferably, the electrode holder also has two symmetrical horizontal grooves, which are connected to the slot.

[0009] Preferably, each of the transverse grooves has a corresponding inclined groove at its upper part, and a limiting rod is placed between the transverse groove and the inclined groove, the diameter of the limiting rod being the same as that of the limiting groove.

[0010] Preferably, the sliding plate has a spherical groove on its side, and the upper part of the motor bracket has multiple holes on both sides. A top block is slidably placed inside the hole, and a spring is placed between the top block and the hole. Under normal conditions, the spring will push the top block out, so that it is softly locked into the spherical groove on the side of the sliding plate.

[0011] Beneficial effects: When it is necessary to connect the wire connector to the battery terminal, when the wire connector is inserted into the slot, the terminal will be connected to the wire connector. At this time, the sliding plate drives the two limit rods to move closer to each other along the trajectory of the horizontal groove, locking the limit groove on the wire connector. At the same time, due to the sliding of the sliding plate, the spherical grooves on both sides of the sliding plate will contact the top block to achieve soft limiting, thus making the installation of the wire connector to the battery terminal completely convenient.

[0018] 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.

[0019] Reference Figures 1 to 5 A terminal locking structure for a square battery includes a conductive busbar support 1. The conductive busbar support 1 has conductive busbars inside that are connected to the positive and negative terminals of multiple square batteries. Wire connecting pieces 2 are provided on both sides of the conductive busbar support 1. The wire connecting pieces 2 are electrically connected to the wire busbars inside the conductive busbar support 1. An electrode support 3 is connected to one side of the wire connecting piece 2. A quick-connect mechanism is provided on the motor support 3 and the wire connecting piece 2.

[0020] Preferably, the quick-connect mechanism includes a limiting groove 201, with limiting grooves 201 provided on both the left and right sides of the wire connecting piece 2.

[0021] Preferably, the quick-connect mechanism further includes: a sliding plate 4, which is slidably connected to the upper part of the electrode support 3. The top of the sliding plate 4 is provided with multiple protrusions to increase friction. The lower part of the sliding plate 4 has two symmetrical inclined grooves 402, which are inclined towards the middle of the electrode support 3. The bottom of the electrode support 3 is also fixedly installed with a pole post 301, which is connected to the bottom of the slot 302. When the wire connecting piece 2 is inserted into the slot 302, the pole post 301 will be connected to the wire connecting piece 2.

[0022] Preferably, the electrode support 3 also has a slot 302 for placing the electrical connecting piece 2 in the middle. The electrode support 3 also has two symmetrical horizontal slots 303, which are connected to the slot 302. Each horizontal slot 303 is connected to a corresponding inclined slot 402 at its upper part. A limiting rod 6 is placed between the horizontal slot 303 and the inclined slot 402. The diameter of the limiting rod 6 is the same as that of the limiting slot 201. When it is necessary to connect the wire connecting piece to the battery terminal, the wire connecting piece 2 is inserted into the slot 302. The terminal 301 will be connected to the wire connecting piece 2. At this time, the friction is increased by the protrusion on the top of the sliding plate 4, which makes the sliding plate 4 slide. The sliding plate 4 will drive the inclined slot 402 at the bottom of the sliding plate 4 to slide. Since the limiting rod 6 is placed inside the inclined slot 402 and the limiting rod 6 is slidably connected to the horizontal slot 303, the sliding of the inclined slot 402 will drive the two limiting rods 6 to move closer to each other along the trajectory of the horizontal slot 303.

[0023] Preferably, the sliding plate 4 has a spherical groove 401 on its side, and the motor bracket 3 has multiple holes on both sides of its upper part. A top block 5 is slidably placed inside the hole, and a spring 501 is placed between the top block 5 and the hole. Under normal conditions, the spring 501 will push the top block 5 out, so that it is softly locked in the spherical groove 401 on the side of the sliding plate 4. The sliding of the sliding plate 4 will cause the spherical grooves 401 on both sides of the sliding plate 4 to contact the top block 5. Since the top block 5 has a spring 501 at the rear, the spring 501 will press the top block 5 tightly into the spherical groove 401 to achieve the limit, thereby completely realizing the convenient installation of the wire connecting piece 2 and the battery terminal 301.

[0024] Working principle: When it is necessary to connect the wire connecting piece 2 to the battery terminal, the wire connecting piece 2 is inserted into the slot 302. The terminal 301 will then connect with the wire connecting piece 2. At this time, the protrusion on the top of the sliding plate 4 increases the friction, causing the sliding plate 4 to slide. The sliding plate 4 will then drive the inclined groove 402 at the bottom of the sliding plate 4 to slide. Since the inclined groove 402 contains a limit rod 6, and the limit rod 6 is slidably connected to the horizontal groove 303, the sliding of the inclined groove 402 will drive the two limit rods 6 to slide along with the horizontal groove 303. As the tracks move closer to each other, the two limiting rods 6 move inward, causing the limiting groove 201 on the wire connecting piece 2 to engage, preventing the wire connecting piece 2 from being pulled out and fixedly installed on the electrode bracket 3. At the same time, the sliding of the sliding plate 4 causes the spherical grooves 401 on both sides of the sliding plate 4 to contact the top block 5. Since the top block 5 is provided with a spring 501 at the rear, the spring 501 will press the top block 5 tightly into the spherical groove 401 to achieve limiting, thereby completely realizing the convenient installation of the wire connecting piece 2 and the battery terminal 301.

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.
