Specific Embodiments
[0019] Refer Figure 1-6 as shown, the battery connector 100 of the first embodiment is used to be installed on a circuit board. When the battery is not inserted, a protective cover 40 covers the battery connector to prevent damage to the positive and negative terminals inside when dust or other conductive elements are inserted improperly.
[0020] The battery connector 100 includes an insulating base 10, a negative terminal 20, and a positive terminal 30. The insulating base 10 includes a bottom wall 11, a peripheral wall 12 extending upward from the bottom wall, and a battery cavity 13 formed by the peripheral wall and the bottom wall for accommodating a button battery (not shown). The negative terminal 20 is disposed on the bottom wall 11 and has a first contact portion 21 protruding upward into the battery cavity 13. The positive terminal 30 includes a second elastic arm 31. The second elastic arm 31 includes a contact portion 311 for abutting against the side surface of the button battery, a locking portion 312 bent and protruding into the battery cavity from the second elastic arm 31, and a blocking portion 313. The blocking portion 313 is in the shape of a vertical plate and lies in the same plane. The two ends thereof can abut against the outer side of the peripheral wall 12. The lower edge of the blocking portion 313 is integrally connected to the second elastic arm 31 by an inclined portion 314. In the present utility model, the blocking portion 313 is in the shape of a vertical flat plate and is connected to the second elastic arm by the inclined portion 314. Thus, the tolerance between the blocking portion 313 and the peripheral wall 12 can be more accurately controlled, and the manufacturing process is also simpler.
[0021] As shown in Figure 5-6 , the positive terminal 30 includes a fixing portion 32 fixed to the peripheral wall and a welding leg 33. The welding leg 33 extends downward from the fixing portion 32. The welding leg is formed by tearing the second elastic arm and forms an elongated opening 315 penetrating the inner and outer surfaces of the second elastic arm.
[0022] Continuing to refer to Figure 5-6 , the second elastic arm 31 is bent and extended from the bottom end of the fixing portion and is in a U-shaped structure. The inner surface of the second elastic arm 31 is folded inward in a V shape to form the contact portion 311. The locking portion 312 is formed by bending the two left and right side walls of the second elastic arm. The locking portion 312 is higher than the contact portion 311. The inclined portion 314 is higher than the blocking portion 313. The lower edges of the two ends of the blocking portion 313 extend downward to form additional portions 3131. The additional portions 3131 are spaced apart from the inclined portion 314, and the lower edge of the additional portion 3131 is higher than or flush with the lower edge of the inclined portion 314. The second elastic arm 31 is provided with a square opening 316 penetrating its inner and outer surfaces, and the square opening penetrates the contact portion in the up and down directions. Further, two elastic arms 121 are cut out from the peripheral wall 12 at a position opposite to the positive terminal, and the upper ends of the elastic arms are provided with locking heads protruding into the battery cavity.
[0023] Referring to Figure 7-8 and Figure 11 , the battery connector 100A of the second embodiment, compared with the battery connector 100, the inclined portion 314A has a radian. Specifically, the inclined portion 314A first depresses downward from the lower edge of the blocking portion 313, and then forms a guiding radian by rounding the upper edge of the second elastic arm 31, which is convenient for the button battery to enter and exit and reduces interference.
[0024] As shown Figure 9-10 in FIG. 3, for the battery connector 100B of the third embodiment, two openings 123 are cut out at the circumferential wall opposite to the positive terminal, and a metal elastic arm 50 is installed at each opening. A latching head 51 protruding into the battery cavity is provided at the upper end of the metal elastic arm. That is, the insulating material elastic arm 121 of the circumferential wall 12 of the battery connector 100 is replaced by the metal elastic arm 50, which is convenient for latching different sizes of button batteries. During blind insertion, the metal elastic arm 50 deforms as the button battery is inserted, which can minimize the impact force on the insulating base 10, thereby improving the overall adaptability and service life of the battery connector 100B.
[0025] As shown Figure 1-3 in FIG. 4, in this embodiment, the protective cover 40 is locked to one side of the insulating base 10. Specifically, a pair of locking portions are spaced apart on one side of the insulating base 10. The protective cover 40 has a pair of elastic arms, and a hook extends downward from the elastic arms and can interfere with the locking portions. An extrusion portion protrudes upward from the elastic arms, and an arrow mark is provided on its surface. When it is necessary to remove the upper cover, a force is applied to the extrusion portion along the arrow direction, and the elastic arms drive the hook into the gap between the locking portions, and the protective cover can be disengaged from the interference of the insulating base.
[0026] The above embodiments are the preferred embodiments of the present invention, rather than all embodiments. Any equivalent changes made by those of ordinary skill in the art to the technical solutions of the present invention by reading the specification of the present invention are covered by the claims of the present invention.
