For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] The present application provides a female connector and a connector, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0042] The FAKRA connector is a common RF (radio frequency) connector used to connect antennas and wireless modules in automobiles and communication equipment. The MINI-FAKRA connector is smaller than the FAKRA connector, but it has a higher frequency and lower insertion loss. Currently, the existing MINI-FAKRA connector only has signal terminals and cannot provide power supply capabilities, making it difficult to meet users' deeper requirements.

[0043] To this end, the present application provides a connector female head 110 and a connector 100, and the connector female head 110 is provided with a power terminal 140 and a signal terminal 130, so that the connector 100 has the functions of signal transmission and power transmission at the same time. The structure of the connector female head 110 and the connector 100 in the present application is described below. This embodiment is only used as an example and does not limit the technical scope of the present application. It can be understood that in the present application, the connector female head 110 and the connector 100 are mainly used in MINI-FAKRA connectors. In other embodiments, the structure of the connector female head 110 and the connector 100 provided in the present application can also be applied to other connectors, which is not limited here.

[0044] For details, see Figure 1 The connector 100 includes a female connector 110 and a male connector 200. The male connector 200 and the female connector 110 are connected along a first direction ( Figure 1 The female connector 110 and the male connector 200 are plugged in (in the X direction), and the female connector 110 is adapted to the male connector 200. The female connector 110 is used as an example for explanation.

[0045] In one embodiment, see Figure 1 and Figure 2The female connector 110 includes a main body 120, which is provided with a first mounting hole 121 and a second mounting hole 122. The first mounting hole 121 and the second mounting hole 122 both extend along the first direction X. A signal terminal 130 is inserted into the first mounting hole 121, and a power terminal 140 is inserted into the second mounting hole 122. Thus, the connector 100 can provide power supply capability without affecting the transmission signal.

[0046] By providing the power terminal 140 and the signal terminal 130 on the connector 100, the transmission of power and signal can be realized at the same time. By inserting the signal terminal 130 into the first mounting hole 121 and the power terminal 140 into the second mounting hole 122, it can be ensured that during the use of the connector 100, the signal terminal 130 and the power terminal 140 are independent of each other and do not affect each other, thereby ensuring the power and signal transmission effect.

[0047] Specifically, a power hole 1215 is opened on the main body 120, and the power hole 1215 is connected to one end of the second mounting hole 122 in the first direction X. The power pin (not shown in the figure) of the connector male head 200 is plugged into the power terminal 140 through the power hole 1215.

[0048] Optional, see Figure 2 and Figure 3 In this embodiment, two first mounting holes 121 are provided, the number of signal terminals 130 corresponds to the number of first mounting holes 121, and a signal terminal 130 is inserted into each first mounting hole 121. Four second mounting holes 122 are provided, the number of power terminals 140 corresponds to the number of second mounting holes 122, and a power terminal 140 is inserted into each second mounting hole 122. By providing two signal terminals 130 and four power terminals 140, the power supply capacity and signal transmission capacity of the connector 100 when in use can be guaranteed.

[0049] It is understandable that in other embodiments, the number of signal terminals 130 and power terminals 140 can be set as needed and is not limited here.

[0050] In one embodiment, see Figure 2 and Figure 3 The female connector 110 also has a second direction ( Figure 1The power terminals 140 and the signal terminals 130 are distributed along the second direction Y. Specifically, when the number of the signal terminals 130 is 2 and the number of the power terminals 140 is 4, the two signal terminals 130 are arranged at intervals along the second direction Y, and the power terminals 140 are evenly distributed on both sides of the signal terminals 130 along the second direction Y. The female connector 110 also has a third direction Z perpendicular to the first direction X and the second direction Y, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Among them, the two power terminals 140 on the same side of the signal terminal 130 are arranged at intervals along the third direction Z.

[0051] The above arrangement helps to modularize the structure of the connector 100, which can reduce the space occupied by the connector 100, optimize the structure of the connector 100, improve product performance and reduce costs.

[0052] In one embodiment, see Figure 4 and Figure 5 The main body 120 is provided with a positioning member 1211, which is connected to the main body 120 and can also be integrally formed. The main body 120 has a first positioning surface 1212, which is arranged in the second mounting hole 122, and the positioning member 1211 has a second positioning surface 1213. The first positioning surface 1212 and the second positioning surface 1213 are arranged opposite to each other in the first direction and are spaced apart from each other. At least part of the power terminal 140 is located between the first positioning surface 1212 and the second positioning surface 1213 in the first direction X. The first positioning surface 1212 and the second positioning surface 1213 cooperate to limit the position of the power terminal 140 in the first direction, so as to achieve preliminary positioning of the power terminal 140.

[0053] In one embodiment, the positioning member 1211 includes a main body 1217 and a positioning portion 1216 that are distributed and connected along the first direction X. The positioning portion 1216 and the main body 1217 are connected to each other. Figure 5 The middle dotted line is a boundary, the positioning portion 1216 is connected to the main body 120 through the main body 1217, and the positioning portion 1216 and the main body 1217 are formed in one piece.

[0054] In one embodiment, see Figure 5 and Figure 6 The female connector 110 further includes a locking member 150 , which is detachably connected to the main body 120 , and is used to limit the positions of the power terminal 140 and the signal terminal 130 in the first direction X.

[0055] Specifically, the locking member 150 includes a connecting portion 151, a clamping portion 152 and a fixing portion 153. The clamping portion 152 is arranged on both sides of the connecting portion 151 in the second direction Y. A positioning groove 123 is provided on the main body 120, and the clamping portion 152 is engaged with the positioning groove 123. In this way, the connection between the locking member 150 and the main body 120 is realized, and the connection method is simple and easy to operate. The fixing portion 153 is arranged on both sides of the connecting portion 151 along the second direction Y. A fixing groove 124 is provided on the main body 120, and the fixing portion 153 is engaged with the fixing groove 124. The fixing portion 153 is used to limit the position of the power terminal 140 and the signal terminal 130 in the first direction X.

[0056] The locking member 150 is provided with an escape groove 154, and the positioning portion 1216 is embedded in the escape groove 154. The escape groove 154 has an escape notch 1541 at one end in the third direction Z. As the locking member 150 is plugged into the main body 120 along the third direction, the positioning portion 1216 is embedded in the escape groove 154 through the escape notch 1541.

[0057] Specifically, at least a portion of the locking member 150 is disposed in the second mounting hole 122, and the locking member 150 has a third positioning surface 1214. In the first direction X, the third positioning surface 1214 is disposed opposite to the first positioning surface 1212 and is spaced apart from each other, and at least a portion of the power terminal 140 is located between the first positioning surface 1212 and the third positioning surface 1214 in the first direction X. By providing the third positioning surface 1214, the third positioning surface 1214 cooperates with the second positioning surface 1212 to position the power terminal 140, and the positioning effect of the power terminal 140 can be further enhanced.

[0058] Further, in the second direction Y, the portion of the locking member 150 having the third positioning surface 1214 is located between the positioning portion 1216 and the power terminal 140. The first positioning surface 1212 is close to the power hole 1215 relative to the second positioning surface 1213 and the third positioning surface 1214; the second positioning surface 1213 is close to the power hole 1215 relative to the third positioning surface 1214 in the first direction X, and the first positioning surface 1212 and the third positioning surface 1214 cooperate to limit the position of the power terminal 140 in the first direction X.

[0059] In this way, by setting the third positioning surface 1214, when the locking of the power terminal 140 by the second positioning surface 1213 fails, that is, when the power terminal 140 slides out from between the first positioning surface 1212 and the second positioning surface 1213, the power terminal 140 can be restricted between the third positioning surface 1214 and the first positioning surface 1212, and the third positioning surface 1214 can play a role of secondary positioning of the power terminal 140 to enhance the connection effect between the power terminal 140 and the connector female head 110.

[0060] It can be understood that in some embodiments, the second positioning surface 1213 and the third positioning surface 1214 can be in the same plane in the first direction X, that is, the straight-line distances between the second positioning surface 1213 and the third positioning surface 1214 and the first positioning surface 1212 are equal. In other embodiments, the second positioning surface 1213 can also be away from the power hole 1215 relative to the third positioning surface 1214 in the first direction (X), which is not limited here.

[0061] By providing the positioning member 1211 and the locking member 150, the power terminal 140 is locked by the second positioning surface 1213 cooperating with the first positioning surface 1212, and then the power terminal 140 is locked by the third positioning surface 1214 on the locking member 150 cooperating with the first positioning surface 1212, so that the positioning effect of the power terminal 140 can be ensured. By enhancing the positioning effect of the power terminal 140, when the connector 100 is in use, the connection between the connector male head 200 and the connector female head 110 can be stable and not easy to loosen, thereby ensuring the transmission effect of the connector 100, making the transmission stable and not easy to be interrupted.

[0062] In some embodiments, see Figure 7 and Figure 8 The locking member 150 is provided with a positioning insert 155, specifically, the positioning insert 155 is fixed on the connecting portion 151. The main body 120 is provided with a positioning slot 125, and the positioning insert 155 is inserted into the positioning slot 125, and the positioning insert 155 is used to limit the position of the signal terminal 130 in the first direction.

[0063] Optional, see Figure 6-Figure 8 The positioning plug 155 includes a first positioning plug 1551 and a second positioning plug 1552. The first positioning plug 1551 is farther away from the positioning member 1211 than the second positioning plug 1552. The first positioning plug 1551 and the second positioning plug 1552 cooperate to limit the position of the signal terminal 130 in the first direction X.

[0064] In this embodiment, two second positioning plugs 1552 are specifically provided, and the second positioning plugs 1552 are spaced apart on both sides of the first positioning plug 1551, and the first positioning plug 1551 and the second positioning plug 1552 are spaced apart in the second direction Y. After the locking member 150 is installed on the main body 120, the signal terminal 130 is stuck between the adjacent first positioning plug 1551 and the second positioning plug 1552. A clamping block 157 is provided on the second positioning plug 1552, and a clamping groove 126 is provided on the inner wall of the main body 120 near the positioning member 1211, and the clamping block 157 is engaged with the clamping groove 126 to realize the connection between the locking member 150 and the main body 120.

[0065] For details, see Figure 4The main body 120 has a fourth positioning surface 1218, and the fourth positioning surface 1218 is arranged in the first mounting hole 121. The positioning plug 155 has a fifth positioning surface 1219. The fourth positioning surface 1218 and the fifth positioning surface 1219 are arranged opposite to each other and spaced apart in the first direction X. At least a part of the signal terminal 130 is located between the fourth positioning surface 1218 and the fifth positioning surface 1219 in the first direction X. The fourth positioning surface 1218 and the fifth positioning surface 1219 cooperate to limit the position of the signal terminal 130 in the first direction X to achieve the positioning of the signal terminal 130 in the first direction X.

[0066] It can be understood that, in other embodiments, the number of the first positioning inserts 1551 and the second positioning inserts 1552 can be set according to the number and arrangement of the signal terminals 130, which is not limited here.

[0067] By providing the first positioning plug 1551 and the second positioning plug 1552, the first positioning plug 1551 and the second positioning plug 1552 can not only cooperate to limit the position of the signal terminal 130 in the first direction X, but also cooperate to limit the position of the signal terminal 130 in the second direction Y, which helps to achieve a better positioning effect and ensure the stability of the signal terminal 130 during installation and use. Furthermore, by engaging the block 157 on the second positioning plug 1552 with the card slot 126, the connection between the locking member 150 and the main body 120 can be further strengthened to make the connection stable.

[0068] In summary, the present application provides a female connector 110 and a connector 100, wherein the female connector 110 includes a power terminal 140 and a signal terminal 130, and the power terminal 140 is preliminarily positioned by the positioning member 1211, and then the power terminal 140 is secondarily positioned by the locking member 150, so as to ensure the positioning effect of the power terminal 140. In addition, the locking member 150 and the main body 120 are first clamped by the clamping portion 152, and then the second clamping is achieved by the clamping block 157 on the second positioning plug 1552, so as to ensure the connection effect between the locking member 150 and the main body 120, so as to achieve a better locking effect.

[0069] The above are only some implementation methods of the embodiments of the present application, and do not constitute any form of limitation on the application. The protection scope of the embodiments of the present application is not limited to this.
