[0034] Example 1

[0035] A new energy battery probe, such as Figure 1 , 2As shown, the probe includes a current needle 1, a voltage needle 2, a heat dissipation ring 3, a base 5, a first spring 4, and a connecting assembly 6. The current needle 1 has a through hole running from front to back. The voltage needle 2 is movably inserted into the central hole of the current needle 1, with both ends protruding beyond the current needle 1. The voltage needle 2 is insulated from the current needle 1 by insulating parts fitted at both ends. Preferably, a third insulating part is provided between the insulating parts at both ends of the voltage needle 2. The third connecting assembly 6 includes a front terminal, a rear terminal, a connecting plate connecting the front and rear terminals, spring washers, and nuts. The connecting assembly 6 is mounted on the rear end of the current needle 1 by two screws clamping the front terminal. The front end of the current needle 1 has a protruding annular limiting end 11, and the outer wall of the front end of the limiting end 11 has an assembly flat part 12. The outer wall of the heat dissipation ring 3 has several parallel heat dissipation fins, and the center of the heat dissipation ring 3 has a through hole, which is a countersunk hole. The diameter of the hole at both ends matches the outer diameter of the limiting end 11 and the outer diameter of the main body of the current needle 1. A heat dissipation ring 3 is fitted onto the front end of the current needle 1, and a limiting end 11 is located within the countersunk hole. Thermally conductive adhesive is filled between the heat dissipation ring 3 and the outer wall of the current needle 1. The length of the limiting end 11 is greater than the depth of the countersunk hole, and its rear wall abuts against the stepped surface of the countersunk hole. The base 5 is a connector between the probe and the external equipment mounting plate. It has a base plate 51 and a sleeve 52 vertically connected to the middle of the rear end face of the base plate 51. The two are integrally formed. The base 5 is fitted onto the current needle 1 through a through hole in its center. A first spring 4 is fitted onto the current needle 1, and the first spring 4 is located between the heat dissipation ring 3 and the base 5. The front end of the first spring 4 abuts against the rear end of the heat dissipation ring 3. A limiting groove is provided at the center of the front end of the base plate 51. The rear end of the first spring 4 abuts against the base 5 within the limiting groove, so that the rear sleeve 52 of the base 5 is always pressed against the connecting assembly 6.

[0036] This invention features a heat dissipation ring installed between the limiting end of the probe current needle and the base, with thermally conductive adhesive filled between the heat dissipation ring and the outer wall of the current needle. This allows the heat dissipation ring to form a higher air convection area during use, improving the probe's heat dissipation function and thus enhancing charging and discharging efficiency.

[0037] Example 2

[0038] like Figure 3-7As shown, this embodiment is basically the same as Embodiment 1, except that in this embodiment, the seat 5 is not a single component, but an assembly composed of a cylinder 53, a front seat plate 54, a rear seat plate 55, a pressure ring 56, and a second spring 57. The cylinder 53 is fitted onto the current needle 1, and an anti-rotation structure is provided between them. The front and rear ends of the cylinder 53 are respectively provided with a front limiting boss 531 and a rear limiting boss 532. The rear end of the cylinder 53 is provided with several circumferentially distributed opening slots 534, which form multiple elastic pressure plates at its front end. The front seat plate 54, rear seat plate 55, second spring 57, and pressure ring 56 are sequentially and movably fitted onto the cylinder 53 from front to back. The front end of the second spring 57 elastically abuts against the rear seat plate 55, and through the rear seat plate 55, the front seat plate 54 always abuts against the front limiting boss 531. The rear end of the second spring 57 elastically abuts against the pressure ring 56, ensuring that the pressure ring 56 always abuts against the rear limiting boss 532. The rear surface of the front seat plate 54 is provided with two positioning bosses 543. The center hole of the front seat plate 54 is a stepped hole 541. The front diameter of the stepped hole 541 matches the outer diameter of the front limiting boss 531, and the rear diameter matches the outer diameter of the main body of the cylinder 53. Furthermore, the depth of the front end of the stepped hole 541 is greater than the length of the front limiting boss 531. The outer wall of the front limiting boss 531 is provided with several circumferentially distributed limiting blocks 533. The front end face of the limiting blocks 533 protrudes from the front end face of the front limiting boss 531. The front end wall of the stepped hole 541 is provided with a sliding groove for accommodating the limiting blocks 533. The sliding groove is a U-shaped groove 542 with one end higher than the other. The rear end of the U-shaped groove 542 is located at the step of the stepped hole 541, and the front end of the U-shaped groove 542 is flush with the front end face of the front seat plate 54. The rear end of the first spring 4 abuts against the front end face of the front limiting boss 531 in the stepped hole 541, so that the cylinder 53 presses against the connecting assembly 6.

[0039] This invention employs a modular base with a front limiting boss and a limiting block at the front end of the cylinder. The front base plate features a U-shaped sliding groove with one end higher than the other. This allows the limiting block to move within the sliding groove, positioning it at either the upper or lower end, creating a rotatable and extendable structure that allows for rapid model changeover according to customer testing needs. Furthermore, the positioning boss on the front base plate, combined with a customer mounting plate, allows adjustment of the spacing between two adjacent probes, accommodating various battery trays.

[0040] This utility model is not limited to the specific embodiments described above. For those skilled in the art, all modifications made based on the above concept without creative effort fall within the protection scope of this utility model.
