Description

Technical Field

[0001] The utility model relates to the technical field of battery seats, in particular to a spring terminal for a battery seat and a battery seat. Background Art

[0002] At present, many electronic products use block batteries as batteries, and the battery holder in the electronic products adopts a long block structure. The battery holder is mainly composed of a plastic holder and a spring terminal. In order to make the spring terminal well abut against the battery and make electrical contact, the spring terminal generally adopts a V-shaped structure. For example, the patent number is: CN201520794685.1, and the name is: a utility model patent for a battery holder that prevents spring deformation and a POS machine with the battery holder. The battery holder recorded in the patent document has a plurality of springs, and the contact portion of the spring is arranged in a lateral V shape. When the battery abuts against the battery holder, the contact portion of the spring is deformed and abuts against the electrode of the battery; since the spring terminal is elastic only in the contact portion, when the battery is used for a long time, the contact portion may partially undergo plastic deformation. When the battery is replaced, the contact portion cannot be 100% restored. After long-term use, the contact portion will gradually lose elasticity, resulting in poor electrical contact with the battery. Summary of the invention

[0006] Furthermore, a middle portion of the abutting portion protrudes outward to form an external convex rib.

[0020] The utility model is described in detail below with reference to the accompanying drawings.

[0021] Example: See Figures 1 to 4A spring terminal for a battery holder, comprising a fixing portion 10 for connecting to a PCB board 30, and an abutting portion 1 for abutting against a battery, wherein the abutting portion 1 is arranged in a lateral V-shape, and a telescopic elastic portion 5 is arranged between the fixing portion 10 and the abutting portion 1, wherein the telescopic elastic portion 5 is arranged in an S-shape, wherein the upper end of one side of the telescopic elastic portion 5 is connected to the lower end of the abutting portion 1, and the lower end of the other side of the telescopic elastic portion 5 is connected to the fixing portion 10.

[0022] When the present technical solution is in use, the spring terminal is combined with the plastic shell of the battery holder, the fixing part 10 is in contact with the electrical contact end of the PCB board 30, and the contact part 1 extends out of the plastic shell; when contacting with the battery, the battery pushes the contact part 1, and the contact part 1 pushes the telescopic elastic part 5, and the contact part 1 and the telescopic elastic part 5 are deformed together, so that the contact part 1 is retracted into the plastic shell or close to the plastic shell. In this process, it is mainly the telescopic elastic part 5 that is deformed; the deformation of the contact part 1 is small, and the deformation of the telescopic elastic part 5 is large; when the battery leaves, the contact part 1 moves outward under the push of the telescopic elastic part 5 and resets; the telescopic elastic part 5 is also reset. Since the maximum deformation of the telescopic length of the telescopic elastic part 5 is relatively large, and when in contact with the battery, the telescopic deformation is relatively small relative to the maximum deformation, the whole can always maintain elasticity.

[0023] Furthermore, the middle portion of the abutting portion 1 protrudes outward to form an outer convex rib 2 .

[0024] During processing, the middle portion of the abutting portion 1 is punched toward one side, and an outer convex rib 2 is formed in the middle portion of the abutting portion 1 ; the outer convex rib 2 can improve the strength of the abutting portion 1 .

[0025] Furthermore, the middle portion of the telescopic elastic portion 5 bulges toward one side to form a middle convex rib 6 .

[0026] In order to improve the strength of the telescopic elastic part 5, the present technical solution adopts the method of punching the middle part of the telescopic elastic part 5 and bulging it toward one side to form a central convex rib 6. The central convex rib 6 can effectively improve the strength and elastic modulus of the telescopic elastic part 5.

[0027] See also Figure 3 , Figure 4 A battery holder, comprising: a plastic holder 20, the plastic holder 20 is provided with a plurality of mounting holes 21, and the mounting holes 21 are provided with the above-mentioned spring terminals.

[0028] Furthermore, a front opening connected to the mounting hole 21 is provided on the front side of the plastic seat 20, the abutting portion 1 extends out of the front opening, a bend portion 4 is provided on the upper end of the abutting portion 1, and the bend portion 4 extends to both sides to form a limiting portion 3, and movable spaces 22 cooperating with the limiting portion 3 are respectively formed on both sides of the mounting hole 21.

[0029] When the present technical solution is in use, the abutting portion 1 is located at the upper end. In order to prevent the upper end of the abutting portion 1 from moving out of the mounting hole 21 when the abutting portion 1 abuts against the battery, the present technical solution provides a bend portion 4 at the upper end of the abutting portion 1, and both sides of the bend portion 4 extend outward to form a limiting portion 3, thereby preventing the abutting portion 1 from moving out of the mounting hole 21.

[0030] Furthermore, a snap-in groove is provided at the lower end of the side wall of the mounting hole 21, and plug-in blocks 7 matching the snap-in groove are respectively provided on both sides of the lower end of the telescopic elastic part 5. An L-shaped gap connected to the outside is provided in the middle of the plug-in block 7, and a suspended block is formed in the L-shaped gap, and the suspended block is bent upward or downward to form a barb 9.

[0031] In order to connect the spring terminal to the plastic seat 20, a clamping groove is set at the lower end of the side wall of the mounting hole 21, and a plug-in block 7 is set at the lower end of the telescopic elastic part 5. The plug-in block 7 is inserted into the clamping groove and prevented from being removed by the barb 9.

[0032] Furthermore, two slits are provided in the middle of the lower end of the telescopic elastic part 5 , and a connecting section connected to the fixing part 10 is formed between the two slits. The connecting section is bent downward, and a locking protrusion 8 is provided on the outer side of the front end of the plug-in block 7 .

[0033] When in use, the mounting hole 21 is located above the PCB board 30, and the fixing portion 10 is located below the telescopic elastic portion 5; secondly, in order to make the lower end of the telescopic elastic portion 5 tightly connected to the card slot through the plug-in block 7, a card protrusion 8 is provided on the front outer side of the plug-in block 7; during installation, due to the provision of two gaps, the front end of the plug-in block 7 can be slightly bent inwardly, so that the card protrusion 8 is inserted into the card slot and abuts against the end face of the card slot. Due to the deformation of the front end of the plug-in block 7, the card protrusion 8 is subjected to a large thrust and abuts against the end face of the card slot, preventing the plug-in block 7 from moving in the card slot.

[0034] The above contents are only preferred embodiments of the utility model. For ordinary technicians in this field, according to the concept of the utility model, there will be changes in the specific implementation method and application scope. The content of this specification should not be understood as a limitation on the utility model.
