Description
Technical Field
[0001] The utility model relates to an electrical connector, in particular to a Type-C female electrical connector. Background Art
[0002] USB electrical connectors have been quite popular as data transmission interfaces. With the continuous improvement of the transmission rate of USB electrical connectors, different specifications have been correspondingly proposed. Currently, the latest specification for portable electronic products is the Type-C electrical connector.
[0003] For some Type-C electrical connectors for special applications, only some of the terminals in the Type-C specification are used, and the useless terminals are removed. Currently, in some regions, for electrical connectors marked with the Type-C specification, it is still necessary to detect whether they meet the Type-C specification before they can be used in that region. Therefore, it is necessary to improve the Type-C female electrical connector for special applications to avoid having to replace the circuit board welded with the Type-C female electrical connector again when switching to a Type-C specification-compliant electrical connector. Content of the Utility Model
[0004] In view of the fact that the Type-C female electrical connector for specific applications cannot meet the Type-C detection specification, the main purpose of the utility model is to provide a pure charging Type-C female electrical connector that can meet the Type-C detection specification.
[0005] The main technical means used to achieve the above purpose is to make the Type-C female electrical connector include:
[0006] A metal shell with a front opening;
[0007] An insulating seat is accommodated in the metal shell and includes a body and a tongue extending from a front end of the body to the front opening of the metal shell, and the tongue includes two opposite first surfaces and a second surface;
[0008] A first Type-C terminal group is fixed in the insulating seat and includes:
[0009] Multiple first power terminals, the front ends of which are located on the first surface of the tongue of the insulating seat, and the rear ends of which are located on the body of the insulating seat; and
[0010] Multiple first signal terminals, the front ends of which are located on the first surface of the tongue of the insulating seat, at least one of the rear ends of the first signal terminals is in the insulating seat, and at least one other rear end of the first signal terminal passes through the body of the insulating seat and exposes from the metal shell; and
[0011] A second Type-C terminal group is fixed in the insulating seat and includes:
[0012] A plurality of second power terminals, the front ends of which are located on the second surface of the tongue of the insulating base; wherein the second power terminals and the corresponding first power terminals are integrally formed to form a plurality of upright sheet-like terminals, and the rear ends of each upright sheet-like terminal pass through the body of the insulating base and expose from the metal housing; and
[0013] A plurality of second signal terminals, the front ends of which are located on the second surface of the tongue of the insulating base, wherein the rear end of at least one first signal terminal is within the insulating base, and the rear end of at least one other second signal terminal passes through the body of the insulating base and exposes from the metal housing.
[0014] As can be seen from the above description, the first and second Type-C terminal groups of the Type-C female end electrical connector of the present utility model conform to the Type-C specification. However, in special applications, the rear ends of at least one first signal terminal of the first Type-C terminal group and at least one second signal terminal of the second Type-C terminal group are located within the insulating base and do not protrude from the metal housing through the insulating base, but it is ensured that other first and second signal terminals pass through the insulating base and protrude from the metal housing; thus, the number of terminals on the tongue of the Type-C female end electrical connector of the present utility model conforms to the Type-C specification, and the number of terminals protruding from the rear end is at most 10, so as to conform to the soldering of the circuit board with corresponding numbers of pads; therefore, for the Type-C female end electrical connector with the number of terminals reduced due to special applications, only the Type-C female end electrical connector of the present utility model needs to be replaced, and there is no need to re-design and produce a new circuit board to conform to the specific address Type-C detection specification. Furthermore, the first and second power terminals are integrally formed and are significantly larger in size than the first and second signal terminals, and have the function of high-power charging.

[0040] The metal housing 10 has a front opening 11 and a rear opening 12.
[0041] The above-mentioned insulating base 20 is received in the metal housing 10 and includes a body 21 and a tongue piece 22. The tongue piece 22 extends from a front side 211 of the body 21 toward the front opening 11 of the metal housing 10 and has a first surface 223 and a second surface 224 that are relatively arranged up and down. In this embodiment, the body 21 has a bottom surface 213 that connects to its rear side 212, and a part of the bottom surface 213 is exposed from the rear opening 12 of the metal housing 10.
[0042] The above-mentioned metal middle partition 30 is embedded in the tongue piece 22 of the insulating base 20. In this embodiment, the metal middle partition 30 includes two sub-middle partitions 31 and a connecting portion 32. The two sub-middle partitions 31 are respectively close to two outer sides 222 of the tongue piece 22 and are partially exposed from the two outer sides 222 of the tongue piece 22. In addition, each sub-middle partition 31 further forms a long through groove 311 and is connected to the connecting portion 32 located inside the body 21. The connecting portion 32 is located above the first Type-C terminal group 40 (as Figure 4A shown), and two pins 33 are respectively formed on two outer sides of the connecting portion 32 to pass through the body 21 and protrude from the rear opening 12 of the metal housing 10.

In this embodiment, the shorter first and second signal terminals 42a, 52a are located at the tongue 22, that is, their rear ends 422, 522 do not extend into the body 21, but the front ends 421, 521 can extend further forward than the front ends 421, 521 of the other first and second signal terminals 42b, 52b.
[0044] The front ends 411 of the first power terminals 41 and the front ends 421 of the D+ terminals, the front ends 421 of the D- terminals, the front ends 421 of the SUB1 terminals and the front ends 421 of the CC1 terminals of the first signal terminals 42 are adjacently arranged on the first surface 221 of the tongue 22 to meet the Type The C connector has sixteen terminal specifications (i.e., excluding eight differential pair terminals), wherein the front ends 411 of the two VBUS terminals and the front ends 411 of the two GND terminals are located on the left and right sides of the front ends 421 of the first signal terminals 42; that is, one of the VBUS terminals of the first power terminals 41 is adjacent to and arranged with one of the GND terminals, and is located on one of the left and right sides of the first signal terminals 42, and the other VBUS terminal is adjacent to and arranged with the other GND terminal, and is located on the other side of the left and right sides of the first signal terminals 42; wherein the adjacent VBUS terminals and GND terminals are located at the front end 221 of the tongue 22, maintaining a first spacing d1; and the two GND terminals of the first power terminals 41 and the first signal terminals 42 are located at the front end 221 of the tongue 22, are equidistantly arranged side by side and flush, and maintain a second spacing d2; wherein the second spacing d2 is smaller than the first spacing d1.
[0045] Similarly, the front ends 511 of the second power terminals 51 and the front ends 521 of the D+ terminal, the front ends 521 of the D- terminal, the front ends 521 of the SUB2 terminal, and the front ends 521 of the CC2 terminal of the second signal terminals 52 are adjacently arranged on the second surface 222 of the tongue 22 to comply with the 16-pin terminal specification of the Type C connector, such as Figure 4BAs shown, the front ends 511 of the two VBUS terminals and the front ends 511 of the two GND terminals of the second power terminals 51 are arranged on the left and right sides of the side-by-side front ends 521 of each terminal of the second signal terminals 52; that is, one of the VBUS terminals of the second power terminals 51 is adjacent to and arranged with one of the GND terminals, and is located on one of the left and right sides of the second signal terminals 52, and the other VBUS terminal is adjacent to and arranged with the other GND terminal, and is located on the other of the left and right sides of the second signal terminals 52; wherein the adjacent VBUS terminals and GND terminals are located at the front end 221 of the tongue 22, maintaining the first spacing d1; and the two GND terminals of the second power terminals 51 and the second signal terminals 52 are located at the front end 221 of the tongue 22, are equidistantly arranged side by side and flush, and maintain the second spacing d2.
[0046] like Figure 1 and Figure 2 As shown, the rear ends 512 of the above-mentioned upright blade terminals, the rear ends 421 of some first signal terminals 42b (such as D+ terminal, D- terminal and CC1 terminal) and the rear ends 521 of some second signal terminals 52b (such as D+ terminal, D- terminal and CC2 terminal) pass through the body 21 of the insulating seat 20 and are exposed from the metal shell 10, while the rear ends 422 of the shorter first signal terminals 42a (such as SBU1) and the rear ends 522 of the shorter second signal terminals 52b (such as SBU2) are located in the tongue 22 of the insulating seat 20 and do not pass out. In this embodiment, the rear ends that pass through the body 21 of the insulating seat 20 and then pass out toward the bottom surface 213 of the body 21 and protrude from the rear opening 12 of the metal shell 10. In this example, the number of terminals exposed in the rear opening 12 of the metal shell 10 is 10.
[0047] In summary, the first and second Type-C terminal groups of the Type-C female end electrical connector of the present utility model conform to the Type-C specification. However, in special applications, the rear ends of at least one first signal terminal of the first Type-C terminal group and at least one second signal terminal of the second Type-C terminal group are located in the insulation base and do not protrude from the metal shell through the insulation base, while other first and second signal terminals pass through the insulation base and protrude from the metal shell. Thus, the number of terminals of the Type-C female end electrical connector of the present utility model located on the tongue conforms to the Type-C specification, and the maximum number of terminals protruding from the rear end is 10, so as to conform to the circuit board with corresponding numbers of pads. Therefore, for the Type-C female end electrical connector with the number of terminals reduced due to special applications, only the Type-C female end electrical connector of the present utility model needs to be replaced, and there is no need to redesign and produce a new circuit board to conform to the Type-C detection specification of a specific address. Moreover, the first and second power terminals are integrally formed and are significantly larger in size than the first and second signal terminals, and have the function of high-power charging.
