[0025] The utility model is further described below in conjunction with specific embodiments and drawings.

[0026] See Figure 4-7 As shown, a battery power connector includes: a terminal 2 and an insulating seat 3, wherein the insulating seat 3 is fixed integrally with the terminal 2 by injection molding to form a non-detachable structure, so that the entire battery power connector structure is extremely stable, and the quality of the battery power connector can be guaranteed, and the service life is longer.

[0027] The battery power connector of the utility model has at least two functions, one of which is to be directly used for connecting the battery, and the other is to be used as a charging connector on a portable electronic product (such as headphones).

[0028] The terminal 2 includes a main body 21, a contact portion 22 bent at the upper end of the main body 21, and a pin portion 23 bent at the lower end of the main body 21. The upper end surface of the contact portion 22 is exposed outside the upper end surface of the insulating seat 3, and the lower end surface of the pin portion 23 is exposed outside the lower end surface of the insulating seat 3.

[0029] In order to position the terminal 2 well to form the insulating seat 3, the portion where the upper end face of the insulating seat 3 contacts the outer edge of the contact portion 22 has no groove; the following design is also made: the main body 21 is provided with a positioning hole 211 for the mold insert to penetrate to position the terminal 2, and the outer side of the insulating seat 3 is also provided with a mold withdrawal hole 31 corresponding to the positioning hole 211; the portion where the insulating seat 3 contacts the outer edge of the contact portion 22 has no groove. That is to say, when the insulating seat 3 is injection molded, the mold insert is penetrated in the positioning hole 211 of the terminal 2 to position the terminal 2, and the positioning stability is good, so that the insulating seat 3 can be better injection molded. Since the mold does not need to use two inserts to position the contact portion 22 of the terminal 2 by clamping, there will be no groove at the portion where the upper end face of the insulating seat 3 contacts the outer edge of the contact portion 22, which ensures the beauty of the appearance, and there is no dust accumulation in the groove, while ensuring the quality of the terminal 2. And after the mold is demolded, the mold insert is withdrawn through the mold withdrawal hole 31, which is convenient for demolding and does not affect the product quality.

[0030] The positioning hole 211 can be directly formed by stamping, wherein the positioning hole 211 is circular, semicircular, polygonal, etc.

[0031] In order to improve the bonding force between the terminal 2 and the insulating seat 3, the following design is also made: the positions corresponding to the positioning holes 211 on both sides of the main body 21 are also formed with positioning parts 212 protruding outward and used to increase the bonding force between the terminal 2 and the insulating seat 3, and the insulating seat 3 wraps the outwardly protruding positioning parts 212, so that the wrapping structure of the two is denser, which can greatly increase the bonding force and stably position the terminal 2 in the insulating seat 3.

[0032] In addition, the end of the contact portion 22 is bent downward to form a first bent portion 24, and the end of the pin portion 23 is bent upward to form a second bent portion 25. The second bent portion 25 is snap-fastened with the first bent portion 24, so that the terminal 2 forms a ring structure. The terminal of this structure has good stability and high structural strength, so that the contact portion 22 and the pin portion 23 can be more stably positioned on the upper and lower surfaces of the insulating seat 3, thereby ensuring the stability and quality of the entire battery power connector. At the same time, the insulating seat 3 is also completely embedded in the terminal 2 of the ring structure, thereby further enhancing the ability of the terminal 2 to combine with the insulating seat 3.

[0033] A dovetail groove 241 is disposed at one end of the first bending portion 24, and a dovetail buckle 251 adapted to the dovetail groove 241 is disposed at one end of the second bending portion 25. The dovetail buckle 251 is pressed into the dovetail groove 241 and fixed by snapping, thereby forming a structurally stable annular structure.

[0034] The other side of the end of the first bending portion 24 is bent to form a blocking piece 242 protruding outward, and a gap 20 is formed between the blocking piece 242 and the other side of the end of the second bending portion 25. The insulating seat 3 is partially integrated into the gap to be fastened to the terminal 2, thereby further enhancing the bonding ability between the terminal 2 and the insulating seat 3.

[0035] The width of the first bending portion 24 is greater than the width of the contact portion 22, so that at least one side of the first bending portion 24 protrudes beyond the side of the contact portion 22, thereby further enhancing the bonding ability between the terminal 2 and the insulating seat 3. The width of the second bending portion 25 is greater than the width of the pin portion 23, so that at least one side of the second bending portion 25 protrudes beyond the side of the pin portion 23, thereby further enhancing the bonding ability between the terminal 2 and the insulating seat 3.

[0036] The upper end surface of the insulating seat 3 is also formed with a step 32, and the lower end surface of the contact portion 22 abuts against the step 32, so that the contact portion 22 will not collapse, thereby ensuring the connection quality between the contact portion 22 and the docking terminal and making the electrical conduction more reliable.

[0037] The contact portion 22 is located above the pin portion 23 and on the same vertical axis, and can adapt to another connector terminal with different PITCH spacing specifications or adapt to two pads of a PCB board with different PITCH specifications.

[0038] The lower end surface of the insulating seat 3 is integrally formed with a first positioning column 33 and a second positioning column 34 that are spaced apart, and the diameters of the first positioning column 33 and the second positioning column 34 are different, so that after the utility model is assembled on the PCB, after the first positioning column 33 and the second positioning column 34 with different diameters are inserted and fixed in two holes on the PCB, its fastening is better, so that the pin portion 23 of the terminal 2 can contact the pad on the PCB more stably, and it is more convenient to weld and fix.

[0039] Positioning grooves 35 are provided on both sides of the insulating seat 3 . The positioning grooves 35 extend downward and pass through the lower end surface of the insulating seat 3 . Positioning blocks 351 are formed in the positioning grooves 35 .

[0040] In summary, the utility model provides a positioning hole 211 for the mold insert to penetrate to position the terminal 2 on the main body 21 of the terminal, and a demolding hole 31 corresponding to the positioning hole 211 is also provided on the outer side of the insulating seat 3; when the insulating seat 3 is injection molded, the mold insert is penetrated in the positioning hole 211 of the terminal 2 to position the terminal 2, and the positioning stability is good, and the insulating seat 3 can be better injection molded. Since the mold does not need to use two inserts to position the contact portion 22 of the terminal 2 by clamping, there will be no groove at the position where the upper end surface of the insulating seat 3 contacts the outer edge of the contact portion 22, thereby ensuring the beauty of the appearance, and there is no dust accumulation in the groove, while ensuring the quality of the terminal 2.
