Description

Technical Field

[0001] The utility model relates to a wire connector, in particular to a wire connector which can control a spring sheet to clamp or release a wire through a lever. Background Art

[0002] A wire connector is a device specifically used to connect wires or conductors. It is widely used in electrical engineering, electronic equipment and various power systems. Among them, a lever-type wire connector is a common connection tool. The user only needs to peel off the outer skin of the wire end and directly insert the wire into the lever-type wire connector to electrically connect the wire to generate conduction.

[0003] Currently, there is a design on the market that releases or clamps the internal spring clip of the wire by toggling a lever. However, compared with traditional connectors, the cost of the lever-type wire connector is generally higher. In the actual manufacturing process, the internal spring clip is usually constructed of two components, so secondary processing is required to complete the manufacturing of the spring clip, and the spring clip and the busbar also need to be connected by riveting or other methods.

[0004] Therefore, if the steps of manufacturing these springs and busbars can be reduced, the cost and time can be significantly reduced. Utility Model Content

[0005] The main purpose of the utility model is to provide a cam-type lever connector, wherein the conductive member in the connector is formed in one piece, and the conductive member and the current collector do not need to be connected to each other by secondary processing or wasting materials.

[0006] The secondary purpose of the utility model is to provide a cam-type lever connector, which can achieve the function of fastening the wire only by relying on the conductive member and the busbar without relying on the support of the shell.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a cam-type lever connector, comprising: a shell, a conductive part, a busbar and a plurality of levers. The shell is configured with a plurality of wire insertion holes along a wire insertion direction, and has a storage space connected to the plurality of wire insertion holes and a plurality of storage grooves adjacent to the storage space; the conductive part has a connecting plate and a plurality of spring sheets extending from the connecting plate as a whole, the connecting plate has an inserting portion extending along the wire insertion direction, the spring sheet has a window portion, a bottom portion, a folded portion and a clamping portion in sequence, the window portion has an opening extending downward from the connecting plate; the busbar has a busbar adjacent to the connecting plate, a busbar extending from the busbar to the A positioning frame extending upward and a plurality of clamping portions extending from the busbar, and the positioning frame and the plurality of clamping portions are respectively arranged on opposite sides of the busbar, the positioning frame is constructed with a frame opening for the insertion portion to pass through, so that the busbar is fixed under the connecting plate; the plurality of levers can be movably assembled to the shell, the lever has a pulling portion and a squeezing portion that can squeeze the spring sheet, the pulling portion can be pulled by a user and swung relative to the shell, so that the squeezing portion presses against the folded portion, so that the clamping portion is separated from the busbar.

[0008] Wherein, when the lever is located at a first position, each clamping portion and the clamping portion of the spring sheet contact each other on the same side of the window portion, and when the lever is swung to a second position relative to the shell, the folded portion will be deformed by the extrusion portion so that the clamping portion leaves the clamping portion, and a spacing distance will be formed between the clamping portion and the clamping portion for each wire to pass through, and at the same time, the clamping portion will swing toward the bottom so as to pass through the opening, and a part of the clamping portion and the connecting plate will be located on the same side of the window portion, and a remaining part of the clamping portion will be located on the other opposite side of the window portion with the bottom.

[0009] In this embodiment, the shell includes a main shell having the accommodating space and a sub-shell having the plurality of accommodating grooves. The main shell includes a first top plate, and the sub-shell includes a second top plate and a lower clamping plate. When the main shell and the sub-shell are combined, a portion of the volume of the first top plate will be clamped between the second top plate and the lower clamping plate.

[0010] In addition, the first top plate also has a fastening piece, and the second top plate has a fastening hole that matches the fastening piece. When the first top plate is inserted between the lower clamping plate and the second top plate, the fastening piece can enter the fastening hole, so that the auxiliary shell is fixed on the main shell.

[0011] In addition, the second top plate has a buckle, and the lever part has a card rail for the buckle to enter. When the lever is in the second position, the buckle can be clamped inside the card rail, so that the lever cannot swing relative to the buckle.

[0012] Furthermore, the housing has a central notch and a test port, and the central notch and the test port are arranged on opposite sides of the housing from the plurality of wire insertion holes. When the lever is in the first position, viewed from the wire insertion holes, the clamping part will block the accommodating groove, and viewed from the test port, the folding part can be directly observed; when the lever is in the second position, viewed from the wire insertion holes, the accommodating groove can be directly observed, and viewed from the test port, the clamping part will block the folding part.

[0013] Finally, the interior of the housing has a plurality of arc-shaped depressions and a guiding plate extending along the wire insertion direction between the arc-shaped depressions. Each arc-shaped depression is arranged below each wire insertion hole. The width of the guiding plate gradually decreases along the wire insertion direction, and there is a gap matching the shape of the guiding plate between the plurality of elastic pieces, so that the conducting member can be installed on the guiding plate along an installation direction opposite to the wire insertion direction, and each folding part can fit into each arc-shaped depression.

[0014] The feature of the present utility model is that the conducting member is integrally formed and has the insertion part extending along the wire insertion direction, and the current collecting member has the positioning frame extending upward from the current collecting plate and a plurality of clamping parts extending from the current collecting plate.

Detailed implementation manners

[0023] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings, and the advantages and features of the present utility model will become clearer as the description progresses.

[0024] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a connector 1 of a cam - type lever 50 of the present utility model is mainly used for connecting a plurality of wires in series or in parallel. The connector 1 includes a housing 2, a conducting member 30, a bus - bar member 40, and a plurality of levers 50. The housing 2 includes a main housing 21 and a sub - housing 22. The main housing 21 is provided with a plurality of wire - insertion holes 211 along a wire - insertion direction D1, and has an accommodation space 212 inside that communicates with the plurality of wire - insertion holes 211. The sub - housing 22 has a plurality of accommodation grooves 221 adjacent to the accommodation space 212, and each of the plurality of accommodation grooves 221 is arranged to align with each of the plurality of wire - insertion holes 211, so that the plurality of wires can be sequentially inserted into the wire - insertion holes 211, the accommodation space 212, and the accommodation grooves 221, and clamped between the conducting member 30 and the bus - bar member 40.

[0025] Please refer to Figure 3 and Figure 4 As shown, the main housing 21 has a first bottom plate 213, a first top plate 214, two first side plates 215 connected between the first bottom plate 213 and the first top plate 214, and a front wall plate 216 having the plurality of wire - insertion holes 211. The sub - housing 22 has a second bottom plate 222, a second top plate 223, two second side plates 224 connected between the second bottom plate 222 and the second top plate 223, and a rear wall plate 225.

[0026] Among them, a lower clamping plate 226 is provided below the second top plate 223. The first top plate 214 can be inserted into the space between the second top plate 223 and the lower clamping plate 226, so that a part of the first top plate 214 is clamped between the second top plate 223 and the lower clamping plate 226. In addition, the first top plate 214 also has two fastening members 214a, and the second top surface has two fastening holes 223a that cooperate with the two fastening members 214a. When the first top surface is inserted between the lower clamping plate 226 and the second top surface, the two fastening members 214a can enter the two fastening holes 223a, so that the first top plate 214 is connected to the second top plate 223.

[0027] Please refer to again Figure 3 and Figure 4 and Figure 6 and Figure 7As shown, the first base plate 213 has two concave holes 213a, and the second base plate 222 has two convex blocks 222a to cooperate with the two concave holes 213a, so that a part of the first base plate 213 can be connected below the second base plate 222. In addition, the second base plate 222 further has a downwardly protruding flange 222b, and the flange 222b can cooperate with the contour of the first base plate 213, so that when the first base plate 213 and the second base plate 222 are connected, a front edge of the first base plate 213 abuts against the flange 222b.

[0028] In addition, the first wall plate 215 has a plug-in portion 215a, and the second wall plate 224 has a side slot 224a extending from the second base plate 222 to the second top surface to cooperate with the plug-in portion 215a. Thus, the main housing 21 and the sub-housing 22 together form a quick-release mechanism through the two fastening members 214a, two fastening holes 223a, two convex blocks 222a, two concave holes 213a, two plug-in portions 215a, and two side slots 224a. A user can easily separate the main housing 21 and the sub-housing 22 by pressing the second top plate 223 and the second base plate 222 of the sub-housing 22 inward.

[0029] Refer again to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the connecting member 30 has a connecting plate 31 and a plurality of elastic pieces 32 integrally extending from the connecting plate 31. The connecting plate 31 has an inserting portion 311 extending along the wire insertion direction D1. The elastic pieces 32 sequentially have a window portion 321, a bottom portion 322, a folding portion 323, and a clamping portion 324. The window portion 321 has an opening 321a extending downward from the connecting plate 31 to the bottom portion 322. The current collecting member 40 has a current collecting plate 41 adjacent to the connecting plate 31, a positioning frame 411 extending upward from the current collecting plate 41, and a plurality of clamping portions 412 extending from the current collecting plate 41. The positioning frame 411 and the plurality of clamping portions 412 are respectively disposed on opposite sides of the current collecting plate 41. Wherein, each clamping portion 412 can respectively pass through each opening 321a, and the positioning frame 411 is configured with a frame opening 411a for the inserting portion 311 to pass through, so that the current collecting member 40 is fixed below the connecting plate 31.

[0030] Among them, the front wall plate 216 further has a plurality of arc-shaped recesses 216a and a guiding plate 216b extending along the wire insertion direction D1 between the arc-shaped recesses 216a. Each arc-shaped recess 216a is disposed below each wire insertion hole 211. The width of the guiding plate 216b tapers along the wire insertion direction D1. There is a gap 33 between the plurality of elastic pieces 32 that matches the shape of the guiding plate 216b, so that the connector 30 can be installed on the guiding plate 216b along an installation direction D2 opposite to the wire insertion direction D1, and each folding portion 323 can fit into each arc-shaped recess 216a. Thus, the plurality of elastic pieces 32 of the connector 30 can be disposed in the accommodating space 212, and the connecting plate 31 of the connector 30 and a part of the bus bar 40 will be inserted into the accommodating groove 221.

[0031] Furthermore, the rear wall plate 225 has a central notch 225a and a test port 225b, and the test port 225b is aligned with one of the plurality of arc-shaped recesses 216a.

[0032] In addition, the plurality of toggle levers 50 are movably assembled above the housing 2. Each toggle lever 50 has a toggling portion 51, two rod portions 52 entering the housing 2, and a pressing portion 53 that can press the elastic piece 32. The two rod portions 52 are connected between the toggling portion 51 and the pressing portion 53. The toggling portion 51 can be toggled by the user to swing relative to the housing 2, so that the pressing portion 53 presses against the folding portion 323 and separates the clamping portion 324 from the bus bar 40.

[0033] Please refer to again Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown in the figures, in this embodiment, when the toggle lever 50 is in a first position S1, each clamping portion 412 and each clamping portion 324 of the elastic piece 32 are in contact with each other on the same side of the window portion 321. And when observed from the wire insertion hole 211, the clamping portion 324 will block the accommodating groove 221, and when observed from the test port 225b, the folding portion 323 can be directly observed.

[0034] In addition, since the positioning frame 411 and the plurality of clamping portions 412 are respectively disposed on opposite sides of the bus bar 41, when each clamping portion 324 applies an upward clamping force to each clamping portion 412, the positioning frame 411 on the opposite side will move downward. However, the bus bar member 40 is combined with the upwardly extending positioning frame 411 and the insertion portion 311, so that the positioning frame 411 receives a downward supporting force. Thus, the clamping force and the supporting force will cancel each other out, and the force balance between the conducting member 30 and the bus bar member 40 is achieved. Furthermore, the connector 1 can fasten the wire only by relying on the conducting member 30 and the bus bar member 40 without relying on the support of the housing 2.

[0035] Please refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, when the lever 50 swings relative to the housing 2 to a second position S2, the folded portion 323 will be deformed by the pressing portion 53 so that the clamping portion 324 leaves the clamping portion 412, and a spacing distance L through which each wire can pass will be formed between the clamping portion 324 and the clamping portion 412. At the same time, the clamping portion 324 will swing toward the bottom 322 and can pass through the opening 321a, so that a part of the clamping portion 324 and the connecting plate 31 are on the same side of the window portion 321, and a remaining part of the clamping portion 324 and the bottom 322 are on the other opposite side of the window portion 321. And from the wire insertion hole 211, the receiving groove 221 can be directly observed. And from the test port 225b, the clamping portion 324 will shield the folded portion 323.

[0036] In addition, the second top plate 223 further has a buckle 223b along the installation direction D2, and the actuating portion 51 has a rail 511 for the buckle 223b to enter. When the lever 50 is in the second position S2, the buckle 223b can be engaged inside the rail 511, so that the lever 50 cannot swing relative to the housing 2.

[0037] Thereby, the user can first move a plurality of toggles 50 to the second position S2 and fix them, causing the elastic pieces 32 to deform, so that each wire can sequentially pass through each wiring hole 211, the accommodating space 212, each opening 321a, and each accommodating groove 221. Then, the user can move the plurality of toggles 50 to the first position S1, causing the elastic pieces 32 to reset and clamping each wire between each clamping portion 324 and each pressing portion 412. Moreover, the user can also insert a test terminal into the accommodating space 212 through the test port 225b and touch the elastic pieces 32 to test whether the plurality of wires are electrically connected.

[0038] In addition, when the bus bar 40 inside the connector 1 is damaged due to long-term use, the user only needs to remove the sub-housing 22 through the quick-release mechanism to expose the bus bar 40, and then draw out the bus bar 40 from below the connection plate 31, so that it can be replaced conveniently and quickly.

[0039] The above description is illustrative rather than restrictive to the present invention. Those of ordinary skill in the art can understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the present invention, and all of them will fall within the protection scope of the present invention.
