[0036] To solve the problems in the background technology, the core inventive concept of the present invention is: integrating 2n power terminals into a power module, which can be directly installed in the female connector later, making it convenient to assemble various female connectors with different numbers of power terminals.

[0037] The present invention is further described in detail below in conjunction with embodiments.

[0038] Specific embodiment 1 of the female connector provided by the present invention: Reference Figure 1-2As shown, the female connector is used to be plugged with the male connector 1, and the female connector includes a front cover 2, a plastic shell 4, a sealing ring 3 extruded in the front cover 2 and the plastic shell 4, a locking plate 5, a power module, a signal terminal for transmitting signals, a sealing body 12 and a tail cover 13. The signal terminal includes a center conductor 8, an outer conductor 9, an insulator 10 and a shielding ring 11.

[0039] In the present invention, except for the front cover 2, the plastic shell 4 and the power module, the remaining parts are all commonly used technical means in the art and will not be described in detail here.

[0040] Reference Figure 1-15 As shown, the molded case 4 has a power terminal installation cavity, in which at least one power module is installed. Figure 1-15 Specifically, one is provided in the figure; each power module includes a power housing 6 and 2n power terminals 7, where n≥1, and each power terminal 7 has an insertion portion 7-1 for inserting a pin of the male connector 1. The power housing 6 is used to be limitedly installed in the power terminal installation cavity of the female connector when in use. The extension direction of the power terminal 7 is defined as the front-to-back direction. The power housing 6 is provided with 2n independent installation cavities 6-7 extending along the front-to-back direction. Each power terminal 7 is respectively installed in a different independent installation cavity 6-7, and each independent installation cavity 6-7 is provided with a terminal limiting structure for limiting the corresponding power terminal 7; a avoidance space is provided at the front end of the power housing 6 for avoiding the pin inserted into the power terminal 7 when the connectors are plugged in.

[0041] In this embodiment, if Figure 1-15 As shown, n=1, and the number of power terminals 7 is specifically two. Figure 3-8 As shown, in this embodiment, the terminal limiting structure includes a limiting hole 6-2 arranged on the side wall of the independent installation cavity 6-7, and the limiting hole 6-2 cooperates with the spring piece 7-2 on the power terminal 7 to limit the extreme position of the power terminal 7 moving backward; at the same time, the terminal limiting structure includes a limiting cantilever 6-4, and the end of the limiting cantilever 6-4 is provided with a convex 6-3 for pressing against the wall of the power terminal installation cavity to deform the limiting cantilever 6-4 and extend into the corresponding independent installation cavity 6-7, and the front end of the limiting cantilever 6-4 has a limiting portion for being located behind the insertion portion 7-1 before the limiting cantilever 6-4 is deformed and located directly behind the insertion portion 7-1 after the limiting cantilever 6-4 is deformed, and the limiting cantilever 6-4 is located on the left side, right side, or both sides of the independent installation cavity 6-7. Among them, the limiting cantilever 6-4 also constitutes a TPA structure (Terminal Position Assurance, a connector terminal holding auxiliary structure, also known as a terminal position assurance structure).

[0042] Before the female connector is assembled, the size of the power terminal installation cavity along the left-right direction is smaller than the size of the power module along the left-right direction. When assembling the female connector, the power module is forcibly installed in the power terminal installation cavity, and the cavity wall of the power terminal installation cavity is pressed and matched with the convex bump 6-3 along the left-right direction, so that the limiting cantilever 6-4 is deformed. After the limiting cantilever 6-4 is deformed, the front end of the limiting cantilever 6-4 is located directly behind the insertion portion 7-1, and the front end of the limiting cantilever 6-4 and the front end of the convex bump 6-3 together constitute a limiting portion, thereby limiting the power terminal 7 from escaping from the independent installation cavity 6-7. The limiting hole 6-2 and the limiting cantilever 6-4 can realize secondary locking of the power terminal 7, ensuring that the position of the power terminal 7 is not deflected, which is convenient for the later insertion of the male connector 1 and the female connector.

[0043] Of course, in other embodiments, the terminal limiting structure may also include only the limiting hole 6-2 or only the limiting cantilever 6-4; according to the size of the bulge 6-3, the limiting portion may also be composed only of the bulge 6-3, or the limiting portion may be composed only of the end of the front end of the limiting cantilever 6-4, which will not be repeated here.

[0044] 2n independent installation cavities 6-7 and terminal limiting structures are used to integrate 2n power terminals 7 into a power housing 6 to form a power module. When manufacturing the female connector, it is not necessary to assemble each power terminal 7 into the plastic shell 4 separately. It is only necessary to assemble the power module into the plastic shell 4. The same power module can adapt to a variety of plastic shells 4, thereby facilitating the assembly of various female connectors with different numbers of power terminals 7. After the female connector is assembled, the avoidance space can clear the pins so that the pins and the power terminals 7 can be normally plugged in.

[0045] Reference Figure 3-8 As shown, in order to conveniently observe whether the power terminal 7 is installed in place, as a specific implementation, the limiting hole 6-2 is a through hole, and the limiting hole 6-2 is located on the left side, right side, or both sides of the independent installation cavity 6-7. After the power terminal 7 is installed in place, the spring piece 7-2 can be observed from the left and right sides of the power housing 6, so that it is convenient to judge whether the power terminal 7 is installed in place. At the same time, when removing the power terminal 7, the power terminal 7 can be easily pulled out backwards by pressing the spring piece 7-2 from the through hole, which is convenient for replacing or repairing the power terminal 7.

[0046] However, in other specific embodiments, the limiting hole 6-2 may be a blind hole. In this case, the blind hole may be located at any side of the limiting hole 6-2, such as the upper side, the lower side, the left side, or the right side. After installation, the power terminal 7 is dragged backwards. If the power terminal 7 cannot be dragged out, it is confirmed that the installation is in place. Of course, a mark such as an indicating scale line may be set at the rear end of the power terminal 7. When the mark is aligned with the rear end of the power housing 6, it is considered that the power terminal 7 has been installed in place.

[0047] like Figure 3-8 As shown, in order to better install the power terminal 7, as a specific implementation, a strip guide block 7-3 extending in the front-to-back direction is provided on the insertion portion 7-1 of the power terminal 7, and the independent installation cavity 6-7 includes a guide groove 6-7-1 that guides and slides with the strip guide block 7-3 in the front-to-back direction. When installing the power terminal 7, first align the strip guide block 7-3 with the guide groove 6-7-1 to ensure that the spring piece 7-2 can enter the limiting hole 6-2 later; then, push the power terminal 7 into the independent installation cavity 6-7.

[0048] like Figure 3-8 As shown, in order to better insert the plug pin into the power terminal 7, as a specific implementation, the front end of the power housing 6 is provided with a trapezoidal guide through hole 6-1 which is respectively connected with each independent installation cavity 6-7 to guide the plug pin when the connector is plugged in, and the trapezoidal guide through hole 6-1 gradually closes from front to back, and the trapezoidal guide through hole 6-1 constitutes the avoidance space. The trapezoidal guide through hole 6-1 can provide guidance for the plug pin during the connector plugging process, so that the plug pin can be better inserted into the power terminal 7 to avoid kneeling of the pin.

[0049] However, in other specific embodiments, the avoidance space may also be a avoidance through hole whose inner diameter is much larger than the outer diameter of the pin. Specifically, for the two power terminals 7, the avoidance through hole may be a long strip avoidance through hole or two avoidance circular holes.

[0050] like Figure 3-12 As shown, in order to conveniently limit the relative position of the power module and the plastic shell 4, as a specific embodiment, the power shell 6 has a narrower section and a wider section, and the transition between the narrower section and the wider section forms a limiting step 6-5 for cooperating with the inner wall stop of the power terminal installation cavity to limit the extreme position of the power shell 6 moving forward, and the outer peripheral surface of the power shell 6 is provided with a barb 6-6 for cooperating with the power terminal installation cavity stop to limit the extreme position of the power shell 6 moving backward. After the female connector is assembled, the barb 6-6 is located in the limiting groove 4-1, and the limiting step 6-5 and the barb 6-6 can limit the position of the power module in the power terminal installation cavity, ensuring the reliability of the pin and the power terminal 7.

[0051] Of course, in other specific embodiments, only the limiting step 6-5 may be provided, and the sealing body 12 and the tail cover 13 may be used to prevent the power module from moving backward; or, only the barbs 6-6 may be provided, and the power module may be shielded by the front cover 2 to prevent the power module from moving forward; or, Figure 1-15As shown, the front cover 2 and the limiting step 6-5 are used to limit the extreme position of the forward movement of the power housing 6, and the barbs 6-6 and the tail cover 13 are used to limit the extreme position of the backward movement of the power housing 6, thereby realizing secondary limiting of the power module and better enabling the pin to be inserted into the power terminal 7 to avoid kneeling of the pin.

[0052] In order to better insert the pin into the insertion portion 7-1 of the power terminal 7, as shown in FIG. Figure 9-15 As shown, the front cover 2 installed at the front end of the plastic shell 4 has a shielding portion 2-1 for shielding the power module in the front and rear directions. The shielding portion 2-1 is provided with a front cover trapezoidal guide through hole 2-1-1 (the cross section of the front cover trapezoidal guide through hole 2-1-1 is a trapezoid) for guiding the pin when the connectors are plugged in. The front cover trapezoidal guide through hole 2-1-1 gradually closes from front to back. At this time, the front cover trapezoidal guide through hole 2-1-1 constitutes the avoidance space, and at the same time, the avoidance space has the function of guiding the pin. When the male connector 1 and the female connector are plugged in, the front cover 2 guides the pin through the guide through hole, so that the pin can be better inserted into the power terminal 7 to avoid kneeling the pin. At the same time, the shielding portion 2-1 is located in front of the power module to protect the power module.

[0053] However, in other specific embodiments, refer to Figure 9-15 As shown, the front cover 2 may also not include the shielding portion 2-1, that is, the front end of the power module is not shielded, and the pin is directly inserted into the power module. At this time, the front end of the front cover 2 constitutes the avoidance space; or, the shielding portion 2-1 is provided with an avoidance through hole whose inner diameter is much larger than the outer diameter of the pin, and the avoidance through hole can be a round hole, a square hole or a special-shaped hole. At this time, the avoidance through hole constitutes the avoidance space.

[0054] In order to better insert the pin into the insertion portion 7-1 of the power terminal 7, as shown in FIG. Figure 9-15 As shown, the rear portion of the shielding portion 2-1 is provided with a slot 2-1-2 for inserting the front ends of all power modules, and the size of the slot 2-1-2 matches the size of the power module to limit the position of the power terminal 7. After the female connector is assembled, the slot 2-1-2 can limit the position of the front end of the power module, ensuring that the trapezoidal guide through hole 6-1 (or avoidance through hole) on the power housing 6 is aligned with the trapezoidal guide through hole 2-1-1 on the front cover of the shielding portion 2-1, so that the pin can be better inserted into the insertion portion 7-1. However, in other specific embodiments, a stop protrusion can also be provided at the rear portion of the shielding portion 2-1, and the stop protrusion contacts the power terminal 7 to limit the extreme position of the forward movement of the power module, and the stop protrusion does not have the function of limiting the front end of the power module.

[0055] In order to better insert the pin into the insertion portion 7-1 of the power terminal 7, as shown in FIG. Figure 9-15As shown, the front cover 2 is provided with a pressing boss 2-2 for extending into the power terminal installation cavity and pressing the front end of the power housing 6 in the left and right directions to limit the position of the power terminal 7 in the power housing 6. When assembling the female connector, the pressing boss 2-2 is located at the side of the front end of the power module and contacts the side of the power module, thereby limiting the relative position of the front end of the power module and the front cover 2, ensuring that the trapezoidal guide through hole 6-1 (or avoidance through hole) on the power housing 6 is aligned with the trapezoidal guide through hole 2-1-1 of the front cover on the shielding portion 2-1, so that the pin can be better inserted into the insertion portion 7-1. However, in other specific embodiments, the pressing boss 2-2 may not be provided, and the slot 2-1-2 may be used to limit the front end of the power module.

[0056] exist Figure 9-15 In the specific embodiment shown, a slot 2-1-2 and a top pressing boss 2-2 are provided on the front cover 2 to perform secondary positioning of the front section of the power module, so as to better ensure that the trapezoidal guide through hole 6-1 (or avoidance through hole) on the power housing 6 is aligned with the front cover trapezoidal guide through hole 2-1-1 on the shielding portion 2-1.

[0057] Specific embodiment 2 of the female connector provided by the present invention: The purpose of this embodiment is to provide a female connector with different numbers of power terminals 7 .

[0058] Reference Figure 1-20 As shown, the main difference between this embodiment and specific embodiment 1 is that in specific embodiment 1, the number of power terminals 7 is two; in this embodiment, the number of power terminals 7 is four, that is, n=2.

[0059] Fig.16 and Fig.17 Two female connectors with different interfaces are disclosed, each of which includes four signal terminals for transmitting signals (only the outer conductor 9 is indicated in the figure), two spare signal terminals (only the spare outer conductor 9' is indicated in the figure), two power terminals 7 (only the corresponding front cover trapezoidal guide holes 2-1-1 are indicated in the figure) and two spare power terminals 7 (only the corresponding spare front cover trapezoidal guide holes 2-1-1' are indicated in the figure). In actual use, when the plastic shell 4 is fixed, the number of signal terminals and power terminals 7 can be adjusted as needed. Figure 1-17 As shown, when manufacturing different female connectors, it is necessary to use a plastic shell 4 of corresponding specifications, but the power module can be universal.

[0060] When the number of power terminals 7 is four, the following are four ways of setting the power module in the female connector: like Fig.18 As shown, the specific setting method and specific structure of the first power module are: The number of power modules is one, and the power terminals 7 form a The terminal limiting structure includes a limiting hole 6-2 and a limiting cantilever 6-4. The limiting hole 6-2 is a through hole.
