Description

Technical Field

[0001] The utility model relates to an electrical connector, in particular to a Type-C female electrical connector. Background Art

[0002] As a data transmission interface, USB electrical connectors have been quite popular. With the continuous improvement of the transmission rate of USB electrical connectors, different specifications have been correspondingly proposed. 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 terminals in the Type-C specification are used, and the useless terminals are removed. At present, 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 changing to a Type-C specification-compliant electrical connector. Summary 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 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 having 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 pass through the body of the insulating seat and are exposed from the metal shell; and

[0010] Multiple first signal terminals, the front ends of which are located on the first surface of the tongue of the insulating seat, the rear end of at least one first signal terminal is in the insulating seat, and the rear ends of at least another first signal terminal pass through the body of the insulating seat and are exposed 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, with their front ends located on the second surface of the tongue of the insulating base and their rear ends passing through the body of the insulating base and exposing from the metal housing; and

[0013] A plurality of second signal terminals, with their front ends located on the second surface of the tongue of the insulating base, wherein the rear ends of at least one first signal terminal are inside the insulating base, and the rear ends of at least one other second signal terminal pass through the body of the insulating base and expose 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 in the insulating base and do not pass through the insulating base to protrude from the metal housing, but it is ensured that there are other first and second signal terminals passing through the insulating base and protruding 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 maximum number of terminals protruding from the rear end is 14, so as to conform to the welding of the circuit board with corresponding pads; therefore, for the Type-C female end electrical connector whose number of terminals is 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 Type-C detection specification of a specific address.

[0042] The above-mentioned first Type-C terminal group 40 and second Type-C terminal group 50 are respectively fixed in the insulating base 20 and are arranged one above the other. The first Type-C terminal group 40 at least includes a plurality of first power terminals 41 and a plurality of first signal terminals 42, and the second Type-C terminal group 50 at least includes a plurality of second power terminals 51 and a plurality of second signal terminals 52; among them, at least one first signal terminal 42a of the first signal terminals 42 is shorter than the first power terminals 41, and at least another first signal terminal 42b is substantially equal in length to the first power terminals 41.

[0043] Moreover, the front ends 411 of the first power terminals 41 are exposed on the tongue piece 22 of the insulating base 20, and the front ends 421 of the D+ terminals, D- terminals, SUB1 terminals, and CC1 terminals of the first signal terminals 42 are adjacent and arranged side by side and flush on the first surface 223 of the tongue piece 22, as Figure 2 andFigure 3 As shown, the front ends 411 of the two VBUS terminals and the front ends 411 of the two GND terminals of the first power terminals 41 are arranged on the left and right sides of the front ends 421 of the first signal terminals 42 side by side according to the specifications of the sixteen terminals of the Type-C connector (i.e., excluding eight differential pair terminals); that is, one VBUS terminal of the first power terminals 41 is adjacent and side by side with one GND terminal, and is located on one of the left and right sides of the first signal terminals 42, and the other VBUS terminal is adjacent and side by side with the other GND terminal, and is located on the other of the left and right sides of the first signal terminals 42; a first distance d1 is maintained between the adjacent VBUS terminal and the GND terminal at the front end 221 of the tongue piece 22; and the two GND terminals of the first power terminals 41 and the first signal terminals 42 are arranged side by side at an equal distance and flush at the front end 221 of the tongue piece 22, and a second distance d2 is maintained; wherein the second distance d2 is less than the first distance d1.

[0044] Similarly, the front ends 511 of the second power terminals 51 are exposed on the tongue piece 22 of the insulating base 20, and the front ends 521 of the D+ terminals, the front ends 521 of the D- terminals, the front ends 521 of the SUB2 terminals, and the front ends 521 of the CC2 terminals of the second signal terminals 52 are adjacent and side by side and flush on the second surface 224 of the tongue piece 22. According to the specifications of the sixteen terminals of the Type-C connector, as Figure 2 and Figure 3 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 front ends 521 of the respective terminals of the second signal terminals 52 side by side; that is, one VBUS terminal of the second power terminals 51 is adjacent and side by side with one GND terminal, and is located on one of the left and right sides of the second signal terminals 52, and the other VBUS terminal is adjacent and side by side with the other GND terminal, and is located on the other of the left and right sides of the second signal terminals 52; a first distance d1 is maintained between the adjacent VBUS terminal and the GND terminal at the front end 221 of the tongue piece 22; and the two GND terminals of the second power terminals 51 and the second signal terminals 52 are arranged side by side at an equal distance and flush at the front end 221 of the tongue piece 22, and the second distance d2 is maintained.

[0045] The rear ends 412 of the respective first power terminals 41, the rear ends 421 of some of the first signal terminals 42b (such as D+ terminal, D- terminal, and CC1 terminal), the rear ends 512 of the respective second power terminals 51, and the rear ends 521 of some of the second signal terminals 52b (such as D+ terminal, D- terminal, and CC2 terminal) pass through the body 21 of the insulation base 20 and are exposed from the metal housing 10 to be soldered to the corresponding pads 61 on the circuit board 60. 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 within the body 21 of the insulation base 20 and do not protrude out. In this embodiment, the rear ends that pass through the body 21 of the insulation base 20 then pass out towards the bottom surface 213 of the body 21, protrude from the rear opening 12 of the metal housing 10, and are bent backward into an L shape, arranged at equal intervals and flush, so as to be surface-soldered to the corresponding pads 61 on the circuit board 60. In addition, the number of pads 61 on the circuit board 60 is less than the number of terminals of the first Type-C terminal group 40 and the second Type-C terminal group 50, and only matches the number of terminals exposed at the rear opening 12 of the metal housing 10. In this example, the number of terminals exposed at the rear opening 12 of the metal housing 10 and the pads on the circuit board are 14.

[0046] In summary, the first and second Type-C terminal groups of the Type-C female 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 insulation base and do not pass through the insulation base to protrude from the metal housing, but other first and second signal terminals pass through the insulation base and protrude from the metal housing; thus, the number of terminals of the Type-C female electrical connector of the present utility model located on the tongue conforms to the Type-C specification, and the maximum number of terminals protruding at the rear end is 14, so as to conform to the soldering of the circuit board with the corresponding number of pads; therefore, for a Type-C female electrical connector with the number of terminals reduced due to special applications, only the Type-C female 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.
