Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically to a female connector. Background Technology

[0002] In the manufacturing process of Type-C female connectors, the upper and lower terminal groups are typically first molded together with the upper and lower insulating components using a molding process (in-mold injection molding) to form two terminal modules. These insulating components are then stacked and assembled. However, current technology requires precise alignment of the upper and lower insulating components during stacking. Misalignment leads to incomplete assembly, causing changes in their relative positions. If the insulating components shift, the previously isolated conductive parts may come into contact, causing a short circuit. For example, in precision electronic devices, such as connectors in mobile phone motherboards, a short circuit can damage the entire circuit board, rendering the device malfunction. Furthermore, internal signal pins may also shift. This alters the characteristics of the signal transmission line, such as increasing impedance, causing signal attenuation or reflection, and affecting signal quality. For connectors used in high-speed signal transmission, such as female connectors for high-speed computer data interfaces, this interference can cause data transmission errors or loss. Therefore, ensuring precise alignment of the upper and lower insulating components during assembly is crucial for secure placement. Utility Model Content

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figures 1 to 4 As shown, a female connector includes a housing 10. An upper terminal module 20 and a lower terminal module 30 are fixed together inside the housing 10. The upper terminal module 20 includes an upper terminal assembly 100 and a first insulating member 200, which are integrally formed by injection molding. The lower terminal module 30 includes a lower terminal assembly 300 and a second insulating member 400, which are integrally formed by injection molding. A receiving groove 210 is provided at the bottom of the first insulating member 200, and a positioning block 410 capable of being inserted into the receiving groove 210 is provided at the top of the second insulating member 400. A plurality of positioning posts 211 are provided in the receiving groove 210, and positioning grooves 411 corresponding to the positions of the positioning posts 211 are provided in the positioning block 410. When the positioning block 410 is inserted into the receiving groove 210, the positioning posts 211 can be embedded in the positioning grooves 411.

[0029] In this embodiment, during assembly, the upper terminal assembly 100 and the first insulating component 200 are first molded together by injection molding to form the upper terminal module 20; the lower terminal assembly 300 and the second insulating component 400 are molded together by injection molding to form the lower terminal module 30. After assembly, the upper terminal module 20 and the lower terminal module 30 are assembled together. During assembly, a positioning block 410 is provided on the top of the second insulating component 400 and inserted into the receiving groove 210 at the bottom of the first insulating component 200, so that the positioning post 211 in the receiving groove 210 can be embedded into the positioning groove 411 in the positioning block 410, thereby fixing the upper terminal module 20 and the lower terminal module 30 together.

[0030] Compared with the prior art, this application provides a receiving groove 210 and a positioning block 410 at the bottom of the first insulating member 200 and the top of the second insulating member 400, respectively. When the upper terminal module 20 and the lower terminal module 30 are assembled, the positioning block 410 is inserted into the receiving groove 210 to achieve the first fixation between the upper terminal module 20 and the lower terminal module 30. In addition, by providing a plurality of positioning posts 211 in the receiving groove 210 and positioning grooves 411 corresponding to the positions of the positioning posts 211 in the positioning block 410, the positioning posts 211 can be embedded in the positioning grooves 411 when the upper terminal module 20 and the lower terminal module 30 are assembled, forming a second fixation between the upper terminal module 20 and the lower terminal module 30, thereby making the fixation between the upper terminal module 20 and the lower terminal module 30 more stable.

[0031] Furthermore, based on the above embodiments, such as Figure 2 As shown, the upper terminal assembly 100 includes a first insertion part 110, a connecting part 120, and a first welding part 130 arranged sequentially. The first insertion part 110 is used to connect with the terminals of the male connector when a male connector is inserted to form an electrical connection. The connecting part 120 is used to connect with the first insulating component 200 through an injection molding process. The first welding part 130 extends from one side of the first insulating component 200 for welding connection with the circuit board. The first insulating component 200 includes a first main body 220, and a first support part 230 extends from one side of the first main body 220. The first insertion part 110 is connected to the first support part 230 and protrudes outward from the top of the first support part 230. The connecting part 120 is disposed inside the first main body 220, and the receiving groove 210 is disposed at the bottom of the first main body 220.

[0032] Furthermore, based on the above embodiments, such as Figure 2 As shown, the lower terminal assembly 300 includes a second insertion part 310 and a second welding part 320 arranged sequentially. The second insertion part 310 is used to connect with the terminal of the male connector to form an electrical connection when the male connector is inserted. The second welding part 320 extends from one side of the second insulating member 400 for welding connection with the circuit board. The second insulating member 400 includes a second main body part 420 and a second support part 430 extending from one side of the second main body part 420. The second insertion part 310 is connected to the second support part 430 and protrudes outward from the bottom of the second support part 430. The positioning block 410 is disposed on the top of the second main body part 420. Thus, when the upper terminal module 20 and the lower terminal module 30 are assembled vertically, the first support part 230 and the second support part 430 are stacked together, and the first main body part 220 and the second main body part 420 are fixed by being inserted into the receiving groove 210 by the positioning block 410.

[0033] Furthermore, based on the above embodiments, such as Figure 3 As shown, there are three positioning posts 211 and positioning grooves 411 arranged in a straight line. A first limiting groove 212 is formed between the positioning post 211 and the inner wall of the receiving groove 210, and a first limiting block 412 is formed between the positioning groove 411 and the outer wall of the positioning block 410. When the positioning post 211 is embedded in the positioning groove 411, the first limiting block 412 can be inserted into the first limiting groove 212, thereby playing an auxiliary positioning role in the embedding position of the positioning post 211 and the positioning groove 411.

[0034] Furthermore, based on the above embodiments, combined with Figure 2 and Figure 4 As shown, a partition 500 is provided between the upper terminal module 20 and the lower terminal module 30, and a limiting step 431 is provided on the top of the second support part 430. The partition 500 is disposed on the limiting step 431 and serves to insulate and separate the upper terminal module 20 and the lower terminal module 30 when they are assembled.

[0035] Furthermore, based on the above embodiments, combined with Figure 3 and Figure 5 As shown, a third insulating member 600 is provided on one side of the first main body 220 and the second main body 420. The third insulating member 600 is formed by injection molding. A second limiting groove 221 is provided on the top of the first main body 220. A positioning plate 610 matching the shape of the second limiting groove 221 is provided outside the third insulating member 600. When the third insulating member 600 is formed on one side of the first main body 220 and the second main body 420 by injection molding, the positioning plate 610 is embedded in the second limiting groove 221, thereby making the connection between the third insulating member 600 and the first main body 220 and the second main body 420 more stable.

[0036] In some embodiments, such as Figure 5 As shown, a fourth insulating member 700 is provided on the side of the third insulating member 600 away from the first main body 220 and the second main body 420. The fourth insulating member 700 is formed around the first insertion part 110 and the second insertion part 310 by injection molding, so that the first insertion part 110 and the second insertion part 310 can protrude from the outer wall of the fourth insulating member 700 respectively. In this way, when the female connector is inserted into the male connector, it can better form an electrical connection with the male connector.

[0037] In some embodiments, combined with Figure 5As shown, buckles 222 are provided at the top and bottom of the third insulating member 600, and a clamping member 710 is provided on the outside of the fourth insulating member 700. A retaining ring 711 is provided on the clamping member 710. When the clamping member 710 is provided on the outside of the fourth insulating member 700, the retaining ring 711 is embedded in the buckle 222, so that the clamping member 710 can allow the fourth insulator to make better contact with the first insertion part 110 and the second insertion part 310.

[0038] Furthermore, based on the above embodiments, combined with Figure 5 and Figure 6 As shown, a third limiting groove 223 is provided at the top and bottom of the third insulating member 600, and at least two second limiting blocks 11 with opposite positions are provided inside the housing 10. When the housing 10 is installed, the second limiting blocks 11 are clamped in the third limiting groove 223 and on one side of the first main body 220, thereby fixing the housing 10 on the upper terminal module 20 and the lower terminal module 30.

[0039] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
