Description

Technical Field

[0001] This invention relates to a wire connector, and more particularly to a wire connector in which the spring clip can be controlled to clamp or release the wire by means of a lever. Background Technology

[0002] A wire connector is a device specifically designed to connect wires or conductors. It is widely used in electrical engineering, electronic equipment, and various power systems. Among them, the lever-type wire connector is a common connection tool. Users only need to strip the outer sheath of the wire end and directly insert the wire into the lever-type wire connector to electrically connect the wires and generate conductivity.

[0003] Currently, there is a design on the market that uses a lever to release or clamp the internal spring of the wire. However, lever-type wire connectors are generally more expensive than traditional connectors. In the actual manufacturing process, the internal spring is usually made of two components, so secondary processing is required to complete the manufacturing of the spring. Furthermore, the spring and the busbar also need to be connected by riveting or other methods.

[0004] Therefore, if the manufacturing process of these springs and busbars can be reduced, costs and time can be significantly reduced. Summary of the Invention

[0005] The main objective of this invention is to provide a connector for a cam-type lever, wherein the guide component in the connector is integrally formed, and the guide component and the busbar do not require secondary processing or material waste to connect to each other.

[0006] A secondary objective of this invention is to provide a connector for a cam-type lever, which can secure the wires by relying only on the guide and the busbar without relying on the support of the housing.

[0007] To achieve the aforementioned objectives, the present invention provides a connector for a cam-type lever, comprising: a housing, a guide member, a busbar, and a plurality of levers. The housing has a plurality of insertion holes along a wiring direction, and internally has an accommodating space communicating with the plurality of insertion holes and a plurality of accommodating slots adjacent to the accommodating space; the guide member has a connecting plate and a plurality of spring contacts integrally extending from the connecting plate, the connecting plate having an insert portion extending along the wiring direction, and the spring contacts sequentially having a window, a bottom, a folded portion, and a clamping portion, the window having an opening extending downward from the connecting plate; the busbar has a busbar plate adjacent to the connecting plate and a slot extending downward from the busbar plate... An upwardly extending positioning frame and a plurality of clamping portions extending from the busbar are provided, with the positioning frame and the plurality of clamping portions respectively disposed on opposite sides of the busbar. The positioning frame has a frame opening through which the insert portion passes, so that the busbar is fixed below the connecting plate. A plurality of levers are movably assembled to the housing. Each lever has a lever with an actuating portion and a pressing portion that can press the spring piece. The actuating portion can be actuated by a user and swing relative to the housing, so that the pressing portion presses against the folding portion, thereby separating the clamping portion from the busbar.

[0008] When the lever is in a first position, each clamping part and the clamping part of the spring contact each other on the same side of the window. When the lever swings relative to the housing to a second position, the folding part is deformed by the squeezing part, causing the clamping part to leave the clamping part. A gap is formed between the clamping part and the clamping part, allowing each wire to pass through. At the same time, the clamping part swings towards the bottom to pass through the opening, and a part of the clamping part is located on the same side of the window with the connecting plate, while the remaining part of the clamping part is located on the opposite side of the window with the bottom.

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

[0010] In addition, the first top plate also has a fastening member, and the second top plate has a fastening hole that engages with the fastening member. When the first top plate is inserted between the lower clamping plate and the second top plate, the fastening member can enter the fastening hole, so that the sub-shell is fixed to the main shell.

[0011] Furthermore, the second top plate has a latch, and the lever has a guide rail that engages with the latch. When the lever is in the second position, the latch can engage with the guide rail, preventing the lever from swinging relative to the latch.

[0012] Furthermore, the housing has a central recess and a test port, and the central recess and the test port are located on opposite sides of the housing along with the plurality of wire insertion holes. When the lever is in the first position, the clamp will block the receiving groove when viewed from the wire insertion hole, while the reverse fold can be directly observed when viewed from the test port. When the lever is in the second position, the receiving groove can be directly observed when viewed from the wire insertion hole, while the clamp will block the reverse fold when viewed from the test port.

[0013] Finally, the housing has a plurality of arc-shaped recesses and a guide plate extending from between the arc-shaped recesses along the insertion direction. Each arc-shaped recess is located below each insertion hole. The width of the guide plate gradually decreases along the insertion direction. There is a gap between the plurality of spring pieces that matches the shape of the guide plate, so that the connector can be installed on the guide plate in an installation direction opposite to the insertion direction, and each fold can fit into each arc-shaped recess.

[0014] The present invention is characterized in that the connector is integrally formed and has the insert portion extending along the insertion direction, and the busbar has the positioning frame extending upward from the busbar plate and a plurality of clamping portions extending from the busbar plate. The positioning frame is configured with the frame opening through which the insert portion passes, so that the busbar can be inserted under the connecting plate along the installation direction, and the clamping portion contacts the clamping portion. Thus, when the plurality of wires are clamped in the busbar and the connector, the upward clamping force on the clamping portion will cancel out the downward supporting force on the positioning frame, so that the connector can secure the wires by relying only on the connector and the busbar.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments and accompanying drawings, and the advantages and features of the present invention will become clearer with the description.

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the present invention discloses a connector 1 for a cam-type lever 50, which is mainly used to connect a plurality of wires in series or in parallel. The connector 1 includes a housing 2, a guide member 30, a bus member 40, and a plurality of levers 50. The housing 2 includes a main housing 21 and a secondary housing 22. The main housing 21 has a plurality of insertion holes 211 along a wire insertion direction D1, and has an accommodating space 212 communicating with the plurality of insertion holes 211. The secondary housing 22 has a plurality of accommodating slots 221 adjacent to the accommodating space 212, and each plurality of accommodating slots 221 is respectively aligned with each plurality of insertion holes 211, so that the plurality of wires can be sequentially inserted into the insertion holes 211, the accommodating space 212, and the accommodating slots 221, and clamped between the guide member 30 and the bus member 40.

[0025] Please see Figure 3 and Figure 4 As shown, the main housing 21 has a first bottom plate 213, a first top plate 214, two first wall 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 insertion holes 211, while the sub-housing 22 has a second bottom plate 222, a second top plate 223, two second wall plates 224 connected between the second bottom plate 222 and the second top plate 223, and a rear wall plate 225.

[0026] The second top plate 223 has a lower clamping plate 226 below it. 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 the following: Figure 3 and Figure 4 as well as Figure 6 and Figure 7As shown, the first base plate 213 has two recesses 213a, and the second base plate 222 has two protrusions 222a to cooperate with the two recesses 213a, so that a part of the first base plate 213 can be connected to the bottom of the second base plate 222. In addition, the second base plate 222 also has a downwardly protruding flange 222b, which 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 leading edge of the first base plate 213 fits against the flange 222b.

[0028] Furthermore, the first wall panel 215 has a plug-in portion 215a, and the second wall panel 224, in conjunction with the plug-in portion 215a, has a side slot 224a extending from the second bottom plate 222 to the second top surface. Thus, the main housing 21 and the sub-housing 22 are connected by the two fastening members 214a, two fastening holes 223a, two protrusions 222a, two recesses 213a, two plug-in portions 215a, and the side slots 224a to form a quick-release mechanism. A user can easily separate the main housing 21 and the sub-housing 22 by simply pressing the second top plate 223 and the second bottom plate 222 of the sub-housing 22 inward.

[0029] See also Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the guide member 30 has a connecting plate 31 and a plurality of spring contacts 32 integrally extending from the connecting plate 31. The connecting plate 31 has an insert portion 311 extending along the insertion direction D1. The spring contacts 32 sequentially have a window portion 321, a bottom portion 322, a folded 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 busbar 40 has a connector adjacent to the connecting plate 31. The busbar 41, a positioning frame 411 extending upward from the busbar 41, and a plurality of clamping portions 412 extending from the busbar 41 are respectively disposed on opposite sides of the busbar 41. Each clamping portion 412 can pass through each opening 321a, and the positioning frame 411 is configured with a frame opening 411a for the insertion portion 311 to pass through, so that the busbar 40 is fixed below the connecting plate 31.

[0030] The front wall panel 216 further includes a plurality of arc-shaped recesses 216a and a guide plate 216b extending from between the arc-shaped recesses 216a along the insertion direction D1. Each arc-shaped recess 216a is located below each insertion hole 211. The width of the guide plate 216b gradually decreases along the insertion direction D1. A gap 33 matching the shape of the guide plate 216b is provided between the plurality of spring tabs 32, allowing the connector 30 to be mounted on the guide plate 216b along an installation direction D2 opposite to the insertion direction D1. Each folded portion 323 can fit against each arc-shaped recess 216a. Thus, the plurality of spring tabs 32 of the connector 30 can be disposed in the receiving space 212, and the connecting plate 31 of the connector 30 and a portion of the busbar 40 are inserted into the receiving groove 221.

[0031] Furthermore, the rear wall panel 225 has a central recess 225a and a test port 225b, the test port 225b being aligned with one of the plurality of arcuate recesses 216a.

[0032] Furthermore, the plurality of levers 50 are movably assembled above the housing 2. Each lever 50 has an actuating part 51, two rod parts 52 that enter the housing 2, and a pressing part 53 that can press the spring piece 32. The two rod parts 52 are connected between the actuating part 51 and the pressing part 53. The actuating part 51 can be actuated by the user and swing relative to the housing 2, so that the pressing part 53 presses against the folding part 323 and separates the clamping part 324 from the manifold 40.

[0033] Please refer to the following: Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in this embodiment, when the lever 50 is in a first position S1, each clamping part 412 and each clamping part 324 of the spring piece 32 are in contact with each other on the same side of the window 321. When viewed from the insertion hole 211, the clamping part 324 will block the receiving groove 221. When viewed from the test port 225b, the folded part 323 can be directly observed.

[0034] Furthermore, since the positioning frame 411 and the plurality of clamping parts 412 are respectively disposed on opposite sides of the busbar 41, when each clamping part 324 applies an upward clamping force to each clamping part 412, the positioning frame 411 on the opposite side will move downward. However, the busbar 40, through the combination of the upwardly extending positioning frame 411 and the inserting part 311, causes the positioning frame 411 to be subjected to a downward supporting force. In this way, the clamping force and the supporting force will cancel each other out, thereby balancing the forces between the guide 30 and the busbar 40. As a result, the connector 1 can achieve the function of fastening the wires by relying only on the guide 30 and the busbar 40 without relying on the support of the housing 2.

[0035] Please refer to the following: 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 folding portion 323 is deformed by the squeezing portion 53, causing the clamping portion 324 to leave the clamping portion 412. A gap distance L is formed between the clamping portion 324 and the clamping portion 412, allowing each wire to pass through. At the same time, the clamping portion 324 swings towards the bottom 322 to pass through the opening 321a, and a part of the clamping portion 324 is located on the same side of the window portion 321 as the connecting plate 31, while the remaining part of the clamping portion 324 is located on the opposite side of the window portion 321 as the bottom 322. The receiving groove 221 can be directly observed from the insertion hole 211, while the clamping portion 324 will block the folding portion 323 when observed from the test port 225b.

[0036] In addition, the second top plate 223 has a buckle 223b along the installation direction D2, and the lever part 51 has a guide rail 511 that engages with the buckle 223b. When the lever 50 is in the second position S2, the buckle 223b can engage with the inside of the guide rail 511, so that the lever 50 cannot swing relative to the housing 2.

[0037] In this way, the user can first move the plurality of levers 50 to the second position S2 and fix them, so that the spring 32 is deformed, allowing each wire to pass through each plug hole 211, the receiving space 212, each opening 321a and each receiving slot 221 in sequence; then move the plurality of levers 50 to the first position S1, so that the spring 32 is reset and clamps each wire in each clamp 324 and each clamping part 412, and the user can also insert a test terminal through the test port 225b into the receiving space 212 and touch the spring 32 to test whether the plurality of wires are conductive.

[0038] Furthermore, when 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 busbar 40, and then pull the busbar 40 out from under the connecting plate 31 for convenient and quick replacement.

[0039] The above description is illustrative only and not restrictive to the present invention. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope of the present invention, and all such modifications, variations or equivalents will fall within the protection scope of the present invention.
