Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to contact-type battery connectors. Background Technology

[0002] Battery connectors, as a crucial component of rechargeable batteries, are widely used in the battery industry. Contact-type battery connectors are a technology that connects electronic devices and batteries via metal contacts. In modern electronic products, battery connectors ensure that electronic devices can reliably draw power from batteries. Contact-type battery connectors involve multiple fields such as materials science, mechanical design, and electrical engineering. With the continuous development of electronic devices, the requirements for contact-type battery connectors are also constantly increasing. For contact-type battery connectors, ensuring a stable and reliable current delivery is crucial.

[0003] Existing contact-type battery connectors are integrated structures with multiple terminals fixed to the connector body, lacking replaceability. Therefore, if a terminal experiences poor contact, the entire connector must be discarded, or even the entire circuit board used to assemble the contact-type battery connector must be scrapped, resulting in waste and hindering the use and maintenance of electronic equipment. To address this, the applicant proposes a dual-row battery connector. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-row battery connector that is replaceable, enables quick disassembly and repair, reduces waste, and facilitates the use and maintenance of electronic equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Dual-row battery connector, which has:

[0007] A plastic base is fixed on a circuit board and has two through holes, each of which has a receiving groove and a plug-in groove arranged in parallel.

[0008] An insulating support base, the shape and size of which match the receiving groove, and an elastic locking mechanism on the insulating support base, so that when the insulating support base is inserted into the receiving groove, the anti-disengagement engagement of the elastic locking mechanism prevents the insulating support base from being removed from the receiving groove; one end of the insulating support base inserted into the receiving groove is provided with multiple terminal slots arranged in rows.

[0009] Several terminals are embedded in terminal slots on an insulating support and are replaceable. Each terminal has a contact portion, a soldering foot, and a fixing portion that connects the contact portion and the soldering foot. The contact portion protrudes from the insulating support and faces the insertion slot so that the contact portion can make contact and conduction with the component inserted into the insertion slot. The soldering foot extends from the insulating support and through a through hole on the plastic base, and is used to solder to the circuit board.

[0010] The above solution is further described as follows: the plastic base is a flat square structure, with two through holes passing through the upper and lower ends of the plastic base and arranged side by side, and an isolation wall between the two through holes; a positioning pin and a fixing foot with a buckle are also provided on the bottom of the plastic base, and the positioning pin and the fixing foot are used to connect the circuit board so that the plastic base is fixed on the circuit board.

[0011] Furthermore, in the above scheme, both the receiving groove and the insertion groove are widened and lengthened from the left and right side walls of the through hole, the insulating support base is a flat body, and the elastic locking is distributed on both ends of the flat direction of the insulating support base and is arranged symmetrically.

[0012] The above solution is further described in that the elastic lock includes a spring arm extending from the side of the insulating support base and a hook extending from the spring arm. The end of the spring arm extends in the opposite direction to the insertion direction of the insulating support base and can protrude from the plastic base for pressing operation. The hook follows the insulating support base into the receiving groove and is fastened to a pre-set hanging platform on the inner side wall of the receiving groove to form an anti-disengagement connection.

[0013] The above solution is further described as follows: the terminal slot is formed by the inward recess of one end of the insulating support seat into the receiving slot, and a pre-compression stop and a locking groove are provided on the inner wall of the terminal slot. The pre-compression stop and the locking groove are respectively provided on the front and rear inner walls of the terminal slot, and the pre-compression stop is close to the insertion slot; the fixing part of the terminal is bent into a U-shape, and the contact part and the welding foot extend from the two ends of the U-shape of the fixing part, respectively. The bottom of the U-shape of the fixing part is inserted into the terminal slot, and the two arms of the U-shape of the fixing part are close to the front and rear inner walls of the terminal slot. A protruding locking point is provided on the U-shaped arm of the fixing part that connects to the welding foot. The locking point engages with the locking groove to establish an anti-detachment connection; the extended end of the contact part is provided with a pre-compression locking foot. The pre-compression locking foot abuts against the pre-compression stop to limit the extent of the contact part protruding from the insulating support seat to the insertion slot.

[0014] The above solution is further described as follows: the contact part is arched, the extended end of the contact part bends inward, and there are two pre-pressing feet symmetrically placed on both sides of the extended end of the contact part.

[0015] The above solution is further described in that the locking point is a partially torn, convex structure of the fixing part, and when the locking point is engaged with the slot, the locking point partially exposes the slot to facilitate unlocking and disassembly.

[0016] The plastic base of this utility model provides a positioning and installation environment, while the insulating support and terminals are detachable and assembleable, enabling the connector to be replaced. Through effective structural design, it can achieve quick disassembly and rapid repair, reduce waste, and help the use and maintenance of electronic equipment. At the same time, it ensures good contact and conductive connection between the terminals and the components inserted into the socket, improving the performance of the connector.

[0024] The following will further explain the concept, specific structure and technical effects of the utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the utility model.

[0025] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0026] See Figures 1-7The diagram shown is a preferred embodiment of the present invention, which relates to a dual-row battery connector mounted on the circuit board of an electronic device for connecting the electronic device to a battery. The dual-row battery connector includes: a plastic base 1, two insulating support seats 2, and several terminals 3 positioned on the insulating support seats.

[0027] The plastic base is fixed to a circuit board (not shown in the figure). Two through holes 11 are provided on the plastic base 1, and each through hole 11 has a receiving groove 12 and a plug-in groove 13 arranged side-by-side. Furthermore, the receiving groove 12 and the plug-in groove 13 are widened and lengthened from the left and right side walls of the through hole 11 to obtain assembly space and meet external plug-in requirements. The widened and lengthened portions also have a guiding function, facilitating implementation. In this embodiment, the plastic base 1 has a flat, square structure. The two through holes 11 penetrate the upper and lower ends of the plastic base 1 and are arranged side-by-side. An isolation wall 14 is provided between the two through holes 11. The isolation wall 14 ensures structural strength and effectively prevents electrical signal interference between the two plug-in grooves 13. A positioning pin 15 and a fixing foot 16 with a buckle are also provided on the bottom of the plastic base 1. The positioning pin 15 and the fixing foot 16 are used to connect to the circuit board, fixing the plastic base 1 to the circuit board. In this embodiment, the fixing feet 16 are harpoon structures with barbs, which facilitate disassembly and assembly. The fixing feet 16 are distributed at the four corners of the bottom of the plastic base, while the positioning pins 15 are distributed on the center line of the bottom of the plastic base. With the above structure, the plastic base can be fixed more stably and accurately on the circuit board, making the connection between the connector and the circuit board more stable and effectively preventing the connector from vibrating and desoldering.

[0028] The insulating support 2 is a flat body, and its shape and size match the receiving groove 12. An elastic locking mechanism 21 is provided on the insulating support 2 so that when the insulating support 2 is inserted into the receiving groove 12, the elastic locking mechanism 21 prevents the insulating support 2 from falling out of the receiving groove 12. In this embodiment, the elastic locking mechanisms 21 are distributed symmetrically on both ends of the flat direction of the insulating support 2 to achieve a stable anti-disengagement connection. One end of the insulating support 2 inserted into the receiving groove has multiple row-arranged terminal slots 22 for assembling terminals 3.

[0029] Several terminals 3 are assembled in a one-to-one manner into the terminal slots 22 on the insulating support base 2, and are replaceable for easy maintenance and repair. In implementation, the terminals are first assembled onto two insulating support bases 2 to form two modules. Then, the insulating support bases 2 are matched with the receiving slots 12, and the two modules are placed side-by-side on the plastic base 1 to construct a double-row battery connector. External components are inserted into the insertion slots 13 and make contact with the terminals to achieve a connection between the electronic device and the battery. The terminal 3 has a contact portion 31, a soldering foot 32, and a fixing portion 33 connecting the contact portion 31 and the soldering foot 32. The contact portion 31 protrudes from the insulating support base 2 and extends towards the insertion slot 13, so that the contact portion 31 can make contact with components inserted into the insertion slot 13. These components can be battery adapters or plugs. The soldering foot 32 extends from the insulating support base 2 through a through hole 11 on the plastic base 1 and is used for soldering to the circuit board.

[0030] Figure 1 , 4 As shown in Figure 6, in this embodiment, the elastic latch 21 includes a spring arm 211 extending from the side of the insulating support base 2 and a hook 212 extending from the spring arm. The end of the spring arm 211 extends in the opposite direction to the insertion direction of the insulating support base 2 and can protrude from the plastic base 1 for pressing operation. The hook 212 follows the insulating support base 2 into the receiving groove 12 and is fastened to a pre-set hanging platform on the inner side wall of the receiving groove, forming an anti-disengagement connection. Utilizing the elasticity of the spring arm 211, during assembly, the hook 212 can automatically pop out and fasten to the pre-set hanging platform on the inner side wall of the receiving groove. When it is necessary to unfasten, pressing the end of the spring arm 211 can drive the hook 212 out of the fastening connection, thereby pulling up the insulating support base 2, realizing quick disassembly and rapid maintenance.

[0031] Figures 2-7As shown, in this embodiment, the terminal slot 22 is formed by an insulating support seat being inserted into the receiving slot at one end, and a pre-pressure stop 221 and a slot 222 are provided on the inner wall of the terminal slot 22. The pre-pressure stop 221 and the slot 222 are respectively provided on the front and rear inner walls of the terminal slot 22, and the pre-pressure stop 221 is close to the insertion slot 13. The fixing part 33 of the terminal is bent into a U-shape, and the contact part 31 and the welding foot 32 extend from the two ends of the U-shape of the fixing part 33, respectively. The bottom of the U-shape of the fixing part 33 is inserted into the terminal slot 22, and the two arms of the U-shape of the fixing part 33 are close to the front and rear inner walls of the terminal slot 22 to increase the stability of the assembly. A protruding locking point 331 is provided on the U-shaped arm of the fixing part that connects to the welding foot. The locking point 331 engages with the slot 222 to establish an anti-detachment connection. The extended end of the contact portion 31 is provided with a pre-compression locking foot 311, which abuts against the pre-compression stop portion 221 to limit the extent of the contact portion 31 protruding from the insulating support 2 towards the insertion groove 13. Furthermore, the contact portion 31 is arched, with its extended end curving inwards, providing good elastic contact capability. Two pre-compression locking feet 311 are symmetrically positioned on both sides of the extended end of the contact portion 31, abutting against each other. Through the elastic deformation characteristics of the contact portion 31, the spring height tolerance of the contact portion 31 can be compensated, ensuring that the spring height of the assembled terminals from different batches can generally maintain a straightness within 0.1 mm, effectively guaranteeing connection reliability.

[0032] In this embodiment, the locking point 331 is a partially torn and protruding structure of the fixing part 33, and when the locking point 331 is engaged with the slot 222, the locking point 331 partially exposes the slot 222 to facilitate unlocking and disassembly, thereby realizing the disassembly, replacement and maintenance of the terminal.

[0033] The plastic base of this utility model provides a positioning and installation environment, while the insulating support and terminals are detachable and assembleable, enabling the connector to be replaced. Through effective structural design, it can achieve quick disassembly and rapid repair, reduce waste, and help the use and maintenance of electronic equipment. At the same time, it ensures good contact and conductive connection between the terminals and the components inserted into the socket, improving the performance of the connector.

[0034] While the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention should not be limited to the same structure and operation as described above and the accompanying drawings. For those skilled in the art, many equivalent improvements and variations can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and variations should all fall within the scope of protection claimed by the present invention.
