Description

Technical Field

[0001] The utility model relates to a connector, in particular to a busbar clip connector and a clamping terminal thereof. Background Art

[0002] Regarding the busbar clip connector, it is mainly applied to electronic devices such as servers and energy storage cabinets. The head end is used to clamp a conductive plate, and several cable wires are connected to the tail end. In terms of clamping the conductive plate, the busbar clip connector uses two clamping terminals opposite to each other to clamp, so as to transmit power.

[0003] Since the clamping terminals must have several elastic arms for clamping closely side by side with each other, it is difficult to be formed in one time. Therefore, the known clamping terminals are changed to a two-piece combination type. The known clamping terminals include: a first independent elastic piece and a second independent elastic piece that exist independently. The first independent elastic piece extends several first elastic arms that are spaced apart and arranged side by side, and the second independent elastic piece extends several second elastic arms that are spaced apart and arranged side by side. The two independent elastic pieces that exist independently are overlapped with each other, and each first elastic arm is located in the gap between any two adjacent second elastic arms, and at the same time, each second elastic arm is located in the gap between any two adjacent first elastic arms. In this way, all the first elastic arms and all the second elastic arms can also be formed to be closely side by side with each other. Since when manufacturing the independent elastic pieces, all the first elastic arms or all the second elastic arms of each independent elastic piece are spaced apart and arranged side by side, the problem that it was originally difficult to be formed in one time is solved.

[0004] However, after the two independent elastic pieces of the known clamping terminals are overlapped with each other, it is necessary to perform processing such as welding or riveting on the parts of the two independent elastic pieces other than the elastic arms in order to be fixed into the required clamping terminals. However, this will instead affect the current transmission of the clamping terminals due to welding or riveting, and the current transmission is crucial for the clamping terminals used to clamp the conductive plate.

[0005] Therefore, how to overcome the above-mentioned deficiencies of the prior art is a major issue that the creator of this application urgently wants to solve. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a busbar clip connector and a clamping terminal thereof that will not affect the current transmission.

[0007] To achieve the above object, the present utility model provides a clamping terminal for a busbar clip connector. The clamping terminal has several thickness edges and includes: a first elastic piece having a first body, at least two first elastic arms, and at least two first gaps. The first body has a protruding edge and a connecting edge. The at least two first elastic arms protrude from the protruding edge of the first body, and each of the first gaps is formed between any two adjacent first elastic arms; a second elastic piece having a second body, at least two second elastic arms, and at least two second gaps. The second body has a protruding edge and a connecting edge. The at least two second elastic arms protrude from the protruding edge of the second body, and each of the second gaps is formed between any two adjacent second elastic arms; and at least one connecting rib, which is integrally connected between the connecting edge of the first body and the connecting edge of the second body. Wherein, the first elastic piece and the second elastic piece are folded with each other with the at least one connecting rib as the folding point, so that the first body and the second body overlap and abut against each other, and each of the first elastic arms correspondingly extends into each of the second gaps, and each of the second elastic arms correspondingly extends into each of the first gaps. The connecting edge of the first body and the connecting edge of the second body together form one of the several thickness edges.

[0008] The present utility model further provides a busbar clip connector connected to several cable wires. The busbar clip connector includes: an insulating body; and a pair of the aforementioned clamping terminals, which are disposed opposite to each other on the insulating body, and the first body and the second body that overlap and abut against each other are also connected to the cable wires.

[0009] Compared with the prior art, the present utility model has the following effects: Since a connecting rib is connected between the connecting edge of the first elastic piece and the connecting edge of the second elastic piece of the clamping terminal, the overlapping and abutting state formed by folding the first elastic piece and the second elastic piece with each other can be fixed by the connecting rib. Therefore, it is no longer necessary to perform processing and fixing between the surfaces of the first body and the second body, thereby having the effect of ensuring that current transmission will not be affected.

[0046] The detailed description and technical content of the present utility model are described as follows in conjunction with the drawings. However, the attached drawings are only for reference and description, and are not intended to limit the present utility model.

[0047] The present utility model provides a bus bar clip connector and its clamping terminal, as Figure 1 shown. One end of the bus bar clip connector L is used to clamp a conductive plate not shown in the figure, and the other end is connected with several cables W. In the figure, Figures 3 to 5 is the first embodiment of the clamping terminal 100 in the present utility model, Figures 8 to 9 and

[0048] is the second embodiment of the clamping terminal 100. Figures 1 to 2 and Figures 6 to 7 shown, the bus bar clip connector L of the present utility model includes an insulating body 500 and a pair of clamping terminals 100. The pair of clamping terminals 100 are arranged opposite to each other on the insulating body 500, and the pair of clamping terminals 100 are spaced apart from each other to form a clamping opening L1 (see Figure 7 ) for clamping the aforementioned conductive plate between one ends of the pair of clamping terminals 100, and the other ends are used to connect the aforementioned cables W (see Figure 2 ).

[0049] As Figure 3 shown, it is the first embodiment of the clamping terminal 100 in a semi-finished product and still in an unfolded state. The clamping terminal 100 is a conductive metal product and includes: a first elastic piece 1, a second elastic piece 2 arranged side by side with each other, and at least one connecting rib 3 connecting between the first elastic piece 1 and the second elastic piece 2.

[0050] The first elastic piece 1 has a first body 11, at least two first elastic arms 12 and at least two first gaps 13. Among them, the first body 11 has several side edges surrounding each other, and these side edges include a protruding edge a, a connecting edge b, a fixed connecting edge c and another edge (not marked with a component symbol). In this first embodiment, the protruding edge a and the connecting edge b are opposite to each other, and the fixed connecting edge c and the other edge are opposite to each other.

[0051] Each of the first elastic arms 12 protrudes from the protruding edge a of the first body 11 side by side at intervals, so that a first gap 13 is formed between any two adjacent first elastic arms 12.

[0052] The second elastic piece 2 has a second body 21, at least two second elastic arms 22 and at least two second gaps 23. Among them, the second body 21 has several side edges surrounding each other, and these side edges also include a protruding edge a, a connecting edge b, a fixed connecting edge c and another edge (not marked with a component symbol). In this first embodiment, the protruding edge a and the connecting edge b are also opposite to each other, and the fixed connecting edge c and the other edge are also opposite to each other. In this way, the connecting edge b of the first body 11 and the connecting edge b of the second body 21 are respectively located at two opposite inner edges of the unfolded clamping terminal 100, and the two protruding edges a are located at two opposite outer edges.

[0053] Each of the second elastic arms 22 protrudes from the protruding edge a of the second body 21 side by side at intervals, so that a second gap 23 is formed between any two adjacent second elastic arms 22.

[0054] In other words, the shape and structure of the second elastic piece 2 are substantially the same as those of the first elastic piece 1. The difference of the second elastic piece 2 is only that: the positions of the second elastic arms 22 correspond to the first gaps 13 of the first elastic piece 1, and the positions of the second gaps 23 correspond to the first elastic arms 12 of the first elastic piece 1.

[0055] The number of the connecting rib pieces 3 is not limited in the present utility model, and can be one or more than one. In this embodiment, two are taken as examples for illustration. Each of the connecting rib pieces 3 is integrally connected between the first elastic piece 1 and the second elastic piece 2. Specifically, it is integrally connected between the connecting edge b of the first body 11 and the connecting edge b of the second body 21 in a bridging manner. Among them, both the first body 11 and the second body 21 have two long sides opposite to each other and two short sides opposite to each other. The protruding edge a and the connecting edge b are the two short sides, and the fixed connecting edge c and the other edge are the two long sides. In other words, in this first embodiment, the connecting edge b of the first body 11 and the connecting edge b of the second body 21 connected with the connecting rib piece 3 Figure 3 both belong to the short sides.

[0056] Such as Figure 4 and Figure 5Shown is the finished product of the first embodiment of the clamping terminal 100. The method is to fold the first elastic piece 1 and the second elastic piece 2 in half with respect to each other, so that the first sheet body 11 and the second sheet body 21 overlap and adhere to each other to jointly form several thickness edges, and each first elastic arm 12 correspondingly extends into each second gap 23, each second elastic arm 22 correspondingly extends into each first gap 13, and each first elastic arm 12 and each second elastic arm 22 are closely arranged side by side with each other. It should be noted that each first elastic arm 12 and each second elastic arm 22 each have a contact portion 121, 221. Preferably, after folding, all the contact portions 121 and all the contact portions 221 are arranged side by side on the same straight line to facilitate the flat electrical contact of the clamping terminal 100 with the aforementioned conductive plate; in addition, the aforementioned folding is carried out with each connecting rib 3 as the folding point (that is, folding with the aforementioned short side), so after folding, the connecting rib 3 will follow to form a bent shape, that is, each connecting rib 3 is bent and connected between two connecting edges b that have overlapped with each other and jointly form a first thickness edge H1 (to be described later).

[0057] Specifically, after folding, the connecting edge b of the first sheet body 11 and the connecting edge b of the second sheet body 21 jointly form the aforementioned first thickness edge H1 of the clamping terminal 100 (see Figure 5 ), the fixed connection edge c of the first sheet body 11 and the fixed connection edge c of the second sheet body 21 jointly form a second thickness edge H2 of the clamping terminal 100 (see Figure 4 ), and as for the protruding edges a of the two sheet bodies and their respective other edges, they will also jointly form a third thickness edge and a fourth thickness edge for which no component symbols are marked.

[0058] Thereby, for the clamping terminal 100 used in the bus bar clip type connector L of the present utility model, since the connecting rib 3 is connected between the connecting edge b of the first elastic piece 1 and the connecting edge b of the second elastic piece 2, the state of overlapping and adhering to each other formed by folding between the first elastic piece 1 and the second elastic piece 2 can be fixed by the connecting rib 3. In this way, it is not necessary to perform processing and fixation between the surfaces of the first sheet body 11 and the second sheet body 21, and the connecting rib 3 is also connected to the first thickness edge H1, so that a complete surface-to-surface adhesion is formed between the first sheet body 11 and the second sheet body 21, thereby having the effect of ensuring that the current transmission is not affected, and can indeed achieve twice the current carrying capacity and is suitable for large currents.

[0059] Preferably, spot welding or fusion welding can also be performed on other thickness edges (such as the second thickness edge H2) of the clamping terminal 100 except for the first thickness edge H1 to further strengthen the fixing strength between the first elastic piece 1 and the second elastic piece 2. It should be noted that since spot welding or fusion welding is also performed on the thickness edge, it will not affect the current transmission either.

[0060] In addition, as shown in Figure 3 andFigure 4 As shown, a first tab 111 and a second tab 211 may also extend integrally from the first body 11 and the second body 21 respectively. Specifically, the first tab 111 and the second tab 211 extend from the fixed edge c of the first body 11 and the fixed edge c of the second body 21 respectively. Both the first tab 111 and the second tab 211 have several surrounding edges, including the surrounding edges 1111 and 2111.

[0061] After folding, the first tab 111 and the second tab 211 also overlap and adhere to each other, which is beneficial for connecting (such as welding, fusing or riveting) the aforementioned cable W here as shown in Figure 2 As shown. Preferably, it can also be bent into an ear-like shape as shown in Figure 6 to connect the cable W. For each clamping terminal 100 applicable to high current, the number of cable Ws connected after folding can be at least two. Therefore, the bus bar clamp connector L of the present utility model is connected to at least four cable Ws in total. In addition, the spot welding or fusing performed to further strengthen the fixing strength as described above can be changed to be performed on the surrounding edge 1111 of the first tab 111 and the surrounding edge 2111 of the second tab 211 (these two surrounding edges 1111 and 2111 overlap each other), so that the first tab 111 and the second tab 211 can not only be used to connect the cable W, but also further strengthen the fixing strength by performing spot welding or fusing. Of course, for the operation of further strengthening the fixing strength by spot welding or fusing, for example, it can also be performed on the aforementioned second thickness edge H2 and the two surrounding edges 1111 and 2111 at the same time.

[0062] It should be further noted that, as shown in Figure 3 and Figure 4 As shown, a surrounding edge of the first tab 111 without component symbols forms a straight line together with the connecting edge b of the first body 11, and a surrounding edge of the second tab 211 without component symbols also forms a straight line together with the connecting edge b of the second body 21. In this way, the first tab 111 and the second tab 211 can be located at the aforementioned other end of the clamping terminal 100, which is beneficial for connecting the cable W.

[0063] As shown in Figure 8 is a second embodiment of the clamping terminal 100 in a semi-finished product and still in an unfolded state. The second embodiment is generally the same as the aforementioned first embodiment, and the difference is only that the connection position of its connecting rib 4 is different from that of the first embodiment, which will be described in detail later.

[0064] The first sheet body 11 and the second sheet body 21 are also both rectangular, and they both have a protruding edge a, a connecting edge b, a fixed connection edge c, and another edge d that surround each other. In each sheet body of the second embodiment, the protruding edge a and the other edge d are opposite to each other, and the connecting edge b and the fixed connection edge c are opposite to each other. In this way, the connecting edge b of the first sheet body 11 and the connecting edge b of the second sheet body 21 are respectively located on two opposite inner edges of the unfolded clamping terminal 100, and the two fixed connection edges c are located on two opposite outer edges. It should be noted that both the first sheet body 11 and the second sheet body 21 have two long sides opposite to each other and two short sides opposite to each other. The protruding edge a and the other edge d are the two short sides, and the connecting edge b and the fixed connection edge c are the two long sides. In other words, in this second embodiment, the connecting edge b of the first sheet body 11 and the connecting edge b of the second sheet body 21 to which the connecting rib 4 is connected are both long sides in Figure 8 this case.

[0065] As Figure 9 shown is the finished product of the second embodiment of the clamping terminal 100. The method is also to fold the first elastic sheet 1 and the second elastic sheet 2 with each connecting rib 4 as the folding point (that is, fold along the aforementioned long sides) so that the first sheet body 11 and the second sheet body 21 overlap and adhere to each other, and each first elastic arm 12 correspondingly extends into each second gap 23, and each second elastic arm 22 correspondingly extends into each first gap 13, and each first elastic arm 12 and each second elastic arm 22 are closely arranged side by side with each other.

[0066] Thereby, the second embodiment of the clamping terminal 100 also has all the effects of the first embodiment.

[0067] In summary, the busbar clip-type connector and its clamping terminal of the present utility model can indeed achieve the expected usage purposes and effects, and can solve the deficiencies of the prior art. Therefore, a patent application is filed.

[0068] The above is only a preferred and feasible embodiment of the present utility model, and it does not limit the scope of the claims of the present utility model. Any equivalent structural changes made by using the content of the specification and drawings of the present utility model are reasonably included in the scope of the rights of the present utility model.
