[0032] In this embodiment, please refer to Figure 5 The first conductive terminal 200 is positioned in the first mounting hole 121. Specifically, the first conductive terminal 200 is sequentially inserted into the second mating cavity 132, the first mounting hole 121, and the first mating cavity 111. The first insertion part 220 is positioned in the first mating cavity 111, the first positioning part 210 is positioned in the first mounting hole 121, and the second insertion part 230 is positioned in the second mating cavity 132.

[0033] In this design, the first positioning boss 211 is positioned on the first positioning step 1211, the outer peripheral surface of the first barb 212 sealably abuts against the inner peripheral surface of the first mounting hole 121, and the first adhesive groove 213 is positioned within the second mating cavity 132, communicating with the second mating cavity 132. By positioning the first positioning boss 211 on the first positioning step 1211 and sealingly abutting the inner peripheral surface of the first mounting hole 121 with the first barb 212, the first conductive terminal 200 can be more firmly fixed to the connector core 100, and the sealing performance between the first conductive terminal 200 and the connector core 100 is improved. In other embodiments, the first positioning boss 211, the first positioning step 1211, and the first barb 212 can all be omitted.

[0034] The second conductive terminal 300 is positioned in the second mounting hole 122. Specifically, the second conductive terminal 300 is sequentially disposed in the second mating cavity 132, the second mounting hole 122, and the first mating cavity 111. The third insertion part 320 is positioned in the first mating cavity 111, the second positioning part 310 is positioned in the second mounting hole 122, and the fourth insertion part 330 is positioned in the second mating cavity 132.

[0035] In this design, the second positioning boss 311 is positioned on the second positioning step 1221, the outer peripheral surface of the second barb 312 sealably abuts against the inner peripheral surface of the second mounting hole 122, and the second adhesive groove 313 is positioned on the second mating cavity 132, communicating with the second mating cavity 132. By positioning the second positioning boss 311 on the second positioning step 1221 and sealingly abutting the inner peripheral surface of the second mounting hole 122 with the second barb 312, the second conductive terminal 300 can be more firmly fixed to the connector core 100, and the sealing performance between the second conductive terminal 300 and the connector core 100 is improved. In other embodiments, the second positioning boss 311, the second positioning step 1221, and the second barb 312 can all be omitted.

[0036] The following describes the assembly method of connector 1000: First, insert the first plug portion 220 of the first conductive terminal 200 into the first mounting hole 121, and push the first conductive terminal 200 until the first positioning boss 211 abuts against the first positioning step 1211; Second, insert the third plug portion 320 of the second conductive terminal 300 into the second mounting hole 122, and push the second conductive terminal 300 until the second positioning boss 311 abuts against the second positioning step 1221; Third, inject glue into the second mating cavity 132.

[0037] After the adhesive solidifies, it forms a positioning adhesive 400, which allows the first conductive terminal 200 and the second conductive terminal 300 to be more securely installed on the connector core 100. Additionally, when the adhesive enters the second mating cavity 132, it also fills the first adhesive groove 213 of the first conductive terminal 200 and the second adhesive groove 313 of the second conductive terminal 300. The solidified positioning adhesive 400, after entering the first and second adhesive grooves 213, provides a limiting effect on the first conductive terminal 200 and the second conductive terminal 300, further securing them to the connector core 100. It can be understood that the positioning adhesive 400, disposed within the second mating cavity 132, is sealed to the second insertion portion 230 and the fourth insertion portion 330, thereby sealingly fixing the first conductive terminal 200 and the second conductive terminal 300 to the connector core 100. In other embodiments, the positioning colloid 400, the first colloid reservoir 213, and the second colloid reservoir 313 can all be omitted.

[0038] In this embodiment, the first plug-in portion 220 and the third plug-in portion 320 are used to plug into one of the external sockets, and the second plug-in portion 230 and the fourth plug-in portion 330 are used to plug into another external socket. The connector 1000 in this embodiment is used on the battery of an electronic product. The second plug-in portion 230 and the fourth plug-in portion 330 are plugged into the battery socket of the electronic product, and the first plug-in portion 220 and the third plug-in portion 320 are plugged into the power socket to achieve electrical connection, thereby enabling battery charging.

[0039] Specifically, when the first connector 220 and the third connector 320 are connected to the power supply socket, the power supply socket extends into the first mating cavity 111 of the first mating cylinder 110 and engages with the first connector 220 and the third connector 320. When the second connector 230 and the fourth connector 330 are connected to the battery socket, the battery socket extends into the second mating cavity 132 of the second mating cylinder 130 and engages with the second connector 230 and the fourth connector 330. By providing the first mating cavity 111 and the second mating cavity 132, it is convenient for the first connector 220 and the third connector 320 to engage with the power supply socket, and also convenient for the second connector 230 and the fourth connector 330 to engage with the battery socket.

[0040] In this embodiment, the first insertion portion 220 and the second insertion portion 230 of the first conductive terminal 200 are configured as pin structures, and the third insertion portion 320 and the fourth insertion portion 330 of the second conductive terminal 300 are configured as pin structures. The pin structure is simple, easier to process, and thus lower in cost. At the same time, the smaller size of the pins is beneficial for the miniaturization design of the connector 1000.

[0041] By setting a second conductive terminal 300 for signal transmission, the connector 1000 can transmit signals in addition to electrical signals, making the connector 1000 more versatile.

[0042] In some embodiments, please refer to Figure 6 and Figure 7The connector 1000 also includes a sealing gasket 500, with a through hole 501 in the center. A positioning plate 123 is provided on the outer peripheral surface of the connecting portion 120, located at the end of the connecting portion 120 near the first mating sleeve 110. The second mating sleeve 130 is inserted into the through hole 501, and the sealing gasket 500 is attached to the surface of the positioning plate 123 facing the second mating sleeve 130. Specifically, the shape of the sealing gasket 500 is the same as that of the positioning plate 123. In this embodiment, the positioning plate 123 is a rectangular plate, with connecting holes 1231 at each of its four corners. The sealing gasket 500 is also a rectangular plate, with through holes 502 at each of its four corners. When the sealing gasket 500 is fitted onto the second mating sleeve 130, the four through holes 502 are respectively aligned with the four connecting holes 1231.

[0043] When using connector 1000, connector 1000 is installed in the housing of electronic device. The second mating sleeve 130 of connector 1000 extends into the housing. Sealing gasket 500 is clamped between the housing and positioning plate 123. Four locking fasteners pass through the four connecting holes 1231 and four through holes 502 of positioning plate 123 and are then locked to the housing. Sealing gasket 500 can seal the gap between positioning plate 123 and housing.
