[0002] With regard to a female connector for a male connector, a plurality of female connectors are provided, and two inner walls of two conductive clamping plates of each female connector are respectively provided with two terminal groups, each of which comprises a plurality of elastic terminals. The terminals of the male connector are inserted into the two terminal groups in a direction of insertion and are elastically clamped by the two terminal groups.

[0003] In order to achieve the elastic clamping function, each elastic terminal is bent at approximately the middle to form an L shape with a clamping angle greater than 90 degrees, and the bending directions of the two terminal groups are opposite to each other.

[0004] Although the terminal groups designed in this way have the ability to elastically clamp the terminals of the male connector, the elastic terminals are designed to achieve the elastic clamping function, which makes the length of the elastic terminals in the direction of insertion too long, resulting in a small clamping force and difficulty in clamping the terminals of the male connector, which has been criticized for a long time.

[0005] Therefore, how to overcome the shortcomings of the prior art is a major problem that the present application inventors want to solve. SUMMARY

[0008] Compared with the prior art, the application has the following effects: the length of each elastic arm in the insertion direction can be shortened, the clamping force of the clamping terminal is effectively improved, the elastic clamping of the inserted terminal is ensured, the contact impedance value is reduced, the transmission current stability is improved, and the large current transmission effect is achieved.

[0046] The detailed description and technical content of the present application are described below in conjunction with the accompanying drawings, however the accompanying drawings are provided for reference and illustration only, and are not intended to limit the present application.

[0047] The present application provides a female connector with enhanced clamping force for use in an electrical connection device (e.g., a terminal block T as shown in FIG. 1, but not limited to the terminal block T, which is described below as an example). Figure 1 As shown in FIG. 1, a first embodiment is shown, and as shown in FIG. 2, a second embodiment is shown. Figures 1 to 6 As shown in FIG. 1, a first embodiment is shown, and as shown in FIG. 2, a second embodiment is shown. Figures 7 to 11 As shown in FIG. 1, a first embodiment is shown, and as shown in FIG. 2, a second embodiment is shown.

[0048] As shown in FIG. 1, a first embodiment is shown, and as shown in FIG. 2, a second embodiment is shown. Figures 2 to 5As shown, the first embodiment of the female connector (referred to as female connector) 100 of the present application has the function of enhancing the clamping force, which is used for inserting a plug-in terminal 900, so as to elastically clamp the plug-in terminal 900 and enable the plug-in terminal 900 and the female connector 100 to be in electrical communication with each other. It should be noted that, as shown Figure 1 As shown, the terminal platform T is provided with a plurality of female connectors 100. The female connector 100 of the present application comprises a carrier 1 and a clamping terminal 3a.

[0049] The carrier 1 has two conductive plates 11, 12 which are spaced apart and arranged side by side. Each conductive plate 11, 12 itself has a width and can be defined as a width direction W as shown. Figure 3

[0050] The clamping terminal 3a is arranged between the two conductive plates 11, 12. The clamping terminal 3a is defined as an insertion direction I for inserting the plug-in terminal 900 and comprises a base body 37 and two terminal groups 31, 32 which are symmetrical to each other.

[0051] The base body 37 has two outer sides (not shown) opposite to each other, and the two terminal groups 31, 32 are connected to the two outer sides respectively. Specifically, the two terminal groups 31, 32 are formed in a state of being bent in the same direction relative to the base body 37, and the two terminal groups 31, 32 are arranged side by side with the base body 37 therebetween.

[0052] Each terminal group 31, 32 comprises a plurality of elastic arms A which are spaced apart and arranged side by side in the aforementioned width direction W. Each elastic arm A has a first arm A1, a second arm A2 and a bending portion A3. Among them, one end of the first arm A1 is connected to the aforementioned outer side of the base body 37, the bending portion A3 is connected between the other end of the first arm A1 and one end of the second arm A2, and the second arm A2 is folded in a V shape relative to the first arm A1 via the bending portion A3, so that the first arm A1 and the second arm A2 after folding have an included angle and are spaced apart and arranged side by side. Moreover, between the two terminal groups 31, 32, two second arms A2 of each transverse row (referring to the thickness direction parallel to the thickness of the conductive plate 11, 12) are located between the two first arms A1. In addition, the first arm A1 and the second arm A2 of each elastic arm A have a first arch D1 and a second arch D2 arching in opposite directions respectively, so that each elastic arm A has two contact points (i.e. the contact points contacted by the first arch D1 and the second arch D2) for electrical connection.

[0053] It should be noted that, as shown Figure 5 In the first embodiment of the female connector 100 of the present application, the clamping terminal 3a sequentially exists along the insertion direction I as follows: all the bending portions A3 first, then the other end of all the second arms A2, and finally the base body 37. ​

[0054] In this way, as Figure 5 and Figure 6 shown, when the plug-in terminal 900 is inserted into the clamping terminal 3a of the female connector 100, the plug-in terminal 900 will be elastically clamped between the two terminal groups 31, 32, except that the first arching portions D1 of the two terminal groups 31, 32 have been elastically abutted against the inner sides of the two conductive plates 11, 12 to form the first contact points, and the second arching portions D2 of the two terminal groups 31, 32 can also elastically abut against the two opposite faces of the plug-in terminal 900 opposite to each other to form the second contact points. Wherein, the first arching portion D1 and the second arching portion D2 of each elastic arm A are opposite and away from each other.

[0055] Therefore, in the case that each elastic arm A still has substantially two contact points, by bending the second arm A2 relative to the first arm A1 through the bending portion A3 to shorten the length of each elastic arm A in the insertion direction I, the clamping force of the clamping terminal 3a can be improved, so as to ensure that the plug-in terminal 900 can be elastically clamped, and also has the effects of reducing the contact impedance value, improving the transmission current stability, and being able to transmit large current. In addition, shortening the length of each elastic arm A in the insertion direction I can also have the effect of shortening the size of the female connector 100 in the insertion direction I, thereby reducing the occupied space.

[0056] As Figure 1 shown, the terminal table T is also provided with a plurality of insertion holes T1 corresponding to each female connector 100, so that the plug-in terminal 900 can be inserted into the female connector 100 through the insertion hole T1.

[0057] As Figures 2 to 5 shown, the clamping terminal 3a further comprises a limiting structure (not shown). The limiting structure comprises a plurality of limiting arms 33, 34, each of which has a groove G. Each of the conductive plates 11, 12 has an edge (or stop edge) facing the insertion direction I, and each of the limiting arms 33, 34 has its groove G engaged on the aforementioned stop edge of the conductive plate 11, 12 to have a certain fixing effect; and each of the limiting arms 33, 34 can also be stopped by the stop edge in the insertion direction I through its groove G to have the effect of preventing the clamping terminal 3a from moving in the insertion direction I.

[0058] Specifically, part of the limiting arms 33 in the plurality of limiting arms 33, 34 are connected to one of the outer side edges of the base body 37, and the other part of the limiting arms 34 in the plurality of limiting arms 33, 34 are connected to the other outer side edge of the base body 37; and the terminal group 31 is located between the part of the limiting arms 33 (each of the limiting arms 33 is arranged side by side with the terminal group 31 in the width direction W), and the terminal group 32 is located between the other part of the limiting arms 34 (each of the limiting arms 34 is arranged side by side with the terminal group 32 in the width direction W).

[0059] In addition, as shown in Figures 3 to 5 In order to limit the clamping terminal 3a, each of the conductive plates 11, 12 can further have two opposite edges (not marked with component symbols) opposite to each other in the width direction W, one of the conductive plates 11 has a limiting rib 111 on each of the two opposite edges, and the other conductive plate 12 also has a limiting rib 121 on each of the two opposite edges, and the limiting ribs 111, 121 on the two conductive plates 11, 12 are opposite to each other (protrude along the aforementioned thickness direction of the conductive plates 11, 12). In this way, the clamping terminal 3a can be limited by the limiting arms 33, 34 in the width direction W, achieving the effect of preventing the clamping terminal 3a from moving in the width direction W.

[0060] As shown in Figures 7 to 11 The second embodiment of the female connector 100 of the present application is substantially the same as the first embodiment, and the difference is that the clamping terminal 3b is different from the first embodiment.

[0061] In the second embodiment, the clamping terminal 3b also includes a base 37, two terminal groups 31, 32 symmetric to each other, and a limiting structure (not marked with component symbols).

[0062] The base 37 has an opening 371, and the base 37 further has two protruding groups 38, 39 protruding in the opposite direction of the protruding direction of the terminal groups 31, 32 corresponding to the opening 371. In detail, the base 37 has two inner sides opposite to each other corresponding to the opening 371, and the two protruding groups 38, 39 are symmetric to each other and connected to the two inner sides respectively, each of the protruding groups 38, 39 includes a plurality of protrusions B spaced apart and arranged side by side, and each of the protrusions B is formed with a third arch D3 for elastically abutting on the plug-in terminal 900 by bending.

[0063] Therefore, as shown in Figure 10 In the second embodiment of the female connector 100 of the present application, the clamping terminal 3b sequentially exists along the insertion direction I as follows: first, all the protrusions B, second, the base 37, third, the other end of all the second arms A2, and finally, all the bending portions A3. In other words, each of the elastic arms A of the second embodiment is folded into an inverted V shape.

[0064] In this way, as shown in Figure 10 and Figure 11As shown, when the plug-in terminal 900 is inserted into the female connector 100, the plug-in terminal 900 will be elastically clamped between the two terminal sets 31, 32 and the two protrusion sets 38, 39. At this time, in addition to the first arching portions D1 of the two terminal sets 31, 32 elastically abutting against the inner sides of the two conductive plates 11, 12 to form the first contact points, the second arching portions D2 of the two terminal sets 31, 32 can also elastically abut against the two opposite surfaces of the plug-in terminal 900 opposite to each other to form the second contact points, and the third arching portions D3 of the two protrusion sets 38, 39 can also elastically abut against the aforementioned two opposite surfaces of the plug-in terminal 900 to form the third contact points.

[0065] Therefore, in addition to having all the effects of the first embodiment, the second embodiment can further improve the contact stability between the clamping terminal 3b and the plug-in terminal 900 and facilitate current transmission due to the addition of the third contact points. In addition, the clamping force of the clamping terminal 3b can also be further improved due to the addition of the third contact points.

[0066] The aforementioned limiting structure of the clamping terminal 3b includes a plurality of limiting lugs 35, 36. Specifically, a portion of the limiting lugs 35 are connected to one of the outer side edges of the base body 37, and another portion of the limiting lugs 36 are connected to the other outer side edge of the base body 37. Moreover, the terminal set 31 is located between the portion of the limiting lugs 35 (each of the limiting lugs 35 is arranged side by side with the terminal set 31 in the width direction W), and the terminal set 32 is located between the other portion of the limiting lugs 36 (each of the limiting lugs 36 is arranged side by side with the terminal set 32 in the width direction W).

[0067] In this way, each of the limiting lugs 35 of the clamping terminal 3b will be stopped by each of the limiting ribs 111 in the insertion direction I, and each of the limiting lugs 36 will be stopped by each of the limiting ribs 121 in the insertion direction I, so as to have the effect of preventing the clamping terminal 3b from being displaced in the insertion direction I. In addition, all of the terminal sets 31, 32 of the clamping terminal 3b can be limited by the limiting ribs 111, 121 in the width direction W, so as to have the effect of preventing the clamping terminal 3b from being displaced in the width direction W.

[0068] In summary, the female connector with the enhanced clamping force function of the present application can achieve the intended use purpose and effect, and can solve the shortcomings of the prior art. Therefore, a patent application is submitted.

[0069] The above description is only a preferred and feasible embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural changes made by applying the contents of the specification and drawings are also included in the scope of the present application, and are hereby declared.
