Description
Technical Field
[0001] The utility model relates to the technical field of wire connection terminals, in particular to a split-type conductive sheet connection terminal. Background Art
[0002] When it is necessary to connect wires, operators usually use common electrical connection devices such as terminal blocks. The PA8, PA10, PA12 and other terminal blocks currently used are made of insulating flame-retardant shells made of plastic, PP or nylon, and integrated internal conductive terminal blocks made of metals such as zinc alloy, iron alloy, copper alloy, etc.
[0003] At present, the internal conductive terminal blocks are all integrated. Due to the different conductivity, torque and cost of different metals, different metals need to be used as internal conductive terminal blocks in different scenarios. When a terminal block made of other materials is needed or the terminal block is damaged and needs to be replaced, it can only be replaced as a whole, which will increase the cost of use.
[0004] Since different metals have different electrical conductivity, torque and cost, different metals need to be used as internal conductive terminals in different scenarios. When a terminal block made of other materials is needed or the terminal block is damaged and needs to be replaced, since the current internal conductive terminal block is integrated, it can only be replaced as a whole, which will increase the cost of use.
[0005] Currently, the integrated conductive terminal block has a metal inner wall thickness limit, and therefore has low compatibility with the diameter of the wire to be connected, and cannot insert multiple wires. Utility Model Content
[0006] The utility model aims to provide a split conductive sheet terminal to solve the problems of being unable to partially replace a metal conductive seat inside the terminal, poor compatibility with wire diameters and being unable to insert multiple wires.
[0007] In order to solve the above technical problems, the utility model provides a split conductive sheet terminal, comprising a terminal housing, wherein the terminal housing comprises a terminal connection housing and a step column.
[0008] The terminal wiring housing is configured with a wiring inner cavity with openings at both ends, the wiring inner cavity is used to pass the wire, a conductive sheet assembly is arranged inside the wiring inner cavity, and the conductive sheet assembly includes an upper conductive sheet and a lower conductive sheet; a step column is fixedly connected to the outer side of the terminal wiring housing, the step column is configured with a screw hole, the screw hole is connected to the wiring inner cavity, and the screw hole is used to install a screw that tightens the wire between the upper conductive sheet and the lower conductive sheet.
[0009] The inner wall of the terminal housing is also fixedly provided with a limit assembly, and the limit assembly includes a pair of inner cavity upper clamping groove protrusions and a pair of inner cavity lower clamping groove protrusions.
[0010] Furthermore, the upper inner cavity clamping groove protrusion and the lower inner cavity clamping groove protrusion are fixedly arranged on the side wall of the wiring inner cavity.
[0011] The upper conductive sheet is pressed between the upper clamping groove protrusion of the inner cavity and the top wall of the wiring inner cavity, and the lower conductive sheet is pressed between the lower clamping groove protrusion of the inner cavity and the bottom wall of the wiring inner cavity.
[0012] Furthermore, the limiting assembly also includes a screw limiting ring and a plurality of screw limiting strips, wherein the screw limiting ring is arranged at the bottom inner side of the step column, and the middle part of the screw limiting ring is the screw hole; the screw limiting strip extends from the opening of the step column to the screw limiting ring, wherein the thickness of the screw limiting strip is smaller than the width of the screw limiting ring.
[0013] Furthermore, the limit assembly also includes an inner cavity upper limit block and an inner cavity lower limit block.
[0014] Furthermore, the inner cavity upper limit block and the inner cavity lower limit block are fixedly arranged at the same opening end of the wiring inner cavity opening.
[0015] Furthermore, the inner cavity upper limit block is fixedly arranged at one end of the wiring inner cavity opening, and the inner cavity lower limit block is fixedly arranged at the other end of the wiring inner cavity opening.

An annular flange is provided around the two screw holes on the side of the upper conductive sheet facing the lower conductive sheet, and the outer diameter of the annular flange is smaller than the distance between the two upper slot protrusions.
[0018] Furthermore, the distance between the upper groove protrusion of the inner cavity and the top wall of the wiring inner cavity is greater than the thickness of the upper conductive sheet, and the distance between the lower groove protrusion of the inner cavity and the bottom wall of the wiring inner cavity is greater than the thickness of the lower conductive sheet.
[0019] Furthermore, the two connecting terminals are fixedly connected via an annular connecting component.
[0020] The beneficial effect of the split conductive sheet terminal provided by the utility model is that: compared with the prior art, the original integrated metal conductive seat is split into an upper conductive sheet and a lower conductive sheet, so that one of the conductive sheets can be replaced according to actual needs, thereby meeting the requirements of conductivity and torque, and one of the conductive sheets can be replaced separately when one of the conductive sheets is damaged. This split design can not only meet the actual standards, but also effectively reduce the cost of use.

DETAILED DESCRIPTION
[0027] In order to better understand the purpose, structure and function of the utility model, the following Figures 1 to 5 , a split conductive sheet terminal of the utility model is further described in detail.
[0028] like Figure 1 and Figure 2As shown, the split conductive sheet terminal of the embodiment of the utility model includes a terminal housing, and the terminal housing includes a terminal wiring housing 2 and a step cylinder 6. Two internal conductive sheets for conducting electricity are arranged inside the terminal wiring housing 2, wherein the internal conductive sheets are located inside the wiring inner cavity 3 of the wiring terminal. The outer side of the terminal wiring housing 2 is fixedly connected with a step cylinder 6, and the step cylinder 6 is provided with a screw hole 61, and the screw hole 61 is connected with the wiring inner cavity 3. When in use, the screw is inserted from the screw hole 61 to press the conductive sheet and the inserted wire, so that the wire and the internal conductive sheet can be firmly connected during use.
[0029] In the present invention, the side of the wiring cavity 3 that is in communication with the screw hole 61 is the top wall, the side of the wiring cavity 3 that is opposite to the top wall is the bottom wall, and the two sides of the wiring cavity 3 that are connected to the top wall are the side walls. The internal conductive sheet includes an upper conductive sheet 11 and a lower conductive sheet 12, the one close to the top wall of the wiring cavity 3 is the lower conductive sheet 12, and the one close to the bottom wall of the wiring cavity 3 is the upper conductive sheet 11.
[0030] A limiting assembly is also provided on the side wall of the wiring inner cavity 3 along the opening direction of the wiring inner cavity 3. The limiting assembly includes a pair of upper inner cavity slot protrusions 41 and a pair of lower inner cavity slot protrusions 42, wherein the upper inner cavity slot protrusions 41 are close to the top wall of the wiring inner cavity 3, and the lower inner cavity slot protrusions 42 are close to the bottom wall of the wiring inner cavity 3. When in use, the upper conductive sheet 11 is pressed between the upper inner cavity slot protrusions 41 and the top wall of the wiring inner cavity 3, and the lower conductive sheet 12 is pressed between the lower inner cavity slot protrusions 42 and the bottom wall of the wiring inner cavity 3, so that the conductive sheets can be ensured to be in stable contact during use to avoid poor contact.
[0031] In actual use, the internal conductive sheet is mainly made of zinc alloy, copper alloy or iron alloy, and different metals can withstand different torques, exhibit different conductivity, and have different use costs. Therefore, it is necessary to use conductive sheets of different materials according to different usage scenarios. Unlike the conventional integrated conductive seat, after using the split conductive sheet, one of the conductive sheets can be replaced separately according to the actual conductivity and torque requirements; or one of the sheets can be replaced separately because one of them is damaged, avoiding the disadvantage of the previous integrated overall replacement, thereby reducing the use cost.
[0032] like Figure 1 and Figure 3 As shown, an annular flange 111 is further provided on one side of the upper conductive sheet 11 along the periphery of the two screw holes, and the outer diameter of the annular flange 111 is smaller than the distance between the two upper clamping groove protrusions 41. When the upper conductive sheet 11 is installed, the side of the upper conductive sheet 11 provided with the annular flange 111 is inserted into the wiring inner cavity 3 toward the position of the lower conductive sheet. The provision of the annular flange 111 can increase the torsional strength of the upper conductive sheet 11 and improve the service life of the conductive sheet.
[0033] In one embodiment, the lower conductive sheet 12 is a conductive sheet without holes, which can more tightly fix the conductive sheet and the conductive wire during use.
[0034] In another embodiment, the lower conductive sheet 12 is a conductive sheet with holes, and the same conductive sheet with holes as the upper conductive sheet 11 is used. This design does not need to distinguish whether the conductive sheet has holes during the production process, which further reduces costs.
[0035] like Figure 2 As shown, a limiting assembly is also provided inside the step column 6, and the limiting assembly includes a screw limiting ring 62 and a plurality of screw limiting strips 63. The screw limiting ring 62 is provided at the bottom of the inner side of the step column 6, and the middle of the screw limiting ring 62 is the screw hole 61. Since the sizes of commonly used screws are basically the same, the purpose of providing the screw limiting ring 62 is to ensure that when the screw body passes through the screw hole 61, the screw head cannot pass through the screw hole 61, so as to prevent the screw from being screwed into the wiring cavity 3, resulting in poor contact of the wire. The screw limit strip 63 extends from the opening of the step cylinder 6 to the screw limit ring 62. This design has two advantages. On the one hand, when the screw is screwed in, the screw head and the screw limit strip 63 always keep in contact. The screw limit strip 63 can ensure that the screw moves only in the direction of screwing in, avoiding the screw from being screwed off when screwed in, resulting in poor contact of the wire; on the other hand, when the screw is screwed out, the screw head also keeps in contact with the screw limit strip 63, so that the screw can be stuck inside the step cylinder 6. After loosening the screw, the screw will not slip out of the step cylinder 6. When it needs to be screwed in again, the screw is still inside the step cylinder 6, and there is no need to find the screw extra, which improves work efficiency. The thickness of the screw limit strip 63 is less than the width of the screw limit ring 62, that is, the screw limit strip 63 does not extend into the screw hole 61, but is always in the screw limit ring 62.
[0036] like Figure 1 and Figure 4 As shown, in the utility model, the limit assembly also includes an inner cavity upper limit block 51 and an inner cavity lower limit block 52, wherein the inner cavity upper limit block 51 is fixedly arranged on the top wall of the wiring inner cavity 3, and after the upper conductive sheet is inserted, the inner cavity upper limit block 51 can abut against the conductive sheet 11, and the inner cavity lower limit block 52 is fixedly arranged on the bottom wall of the wiring inner cavity 3, and after the lower conductive sheet is inserted, the inner cavity lower limit block 52 can also abut against the conductive sheet 12, thereby preventing the conductive sheet from slipping out of the wiring terminal.
[0037] In one embodiment, the inner cavity upper limit block 51 and the inner cavity lower limit block 52 are fixedly arranged at the same opening end of the wiring inner cavity 3, so that the conductive sheet can be conveniently inserted at the same end, thereby improving the use efficiency.
[0038] like Figure 5As shown, in another embodiment, the inner cavity upper limit block 51 is fixed at one end of the opening of the wiring inner cavity 3, and the inner cavity lower limit block 52 is fixed at the other end of the opening of the wiring inner cavity 3. This design makes the direction in which the wire enters and the direction in which the conductive sheet is inserted the same, and the wire can drive the conductive sheet to abut more closely.
[0039] like Figure 1 , Figure 4 and Figure 5 When in use, the upper conductive sheet 11 is inserted into the wiring inner cavity 3 through the space between the top wall of the wiring inner cavity 3 and the upper groove protrusion 41 of the inner cavity, on the side where the inner cavity upper limit block 51 is not provided. Due to the inner cavity upper limit block 51, the upper conductive sheet 11 will not slide out from the other side after being inserted. The lower conductive sheet 12 is inserted into the wiring inner cavity 3 through the space between the bottom wall of the wiring inner cavity 3 and the lower groove protrusion 42 of the inner cavity from the side where the inner cavity lower limit block 52 is not provided. Similarly, due to the provision of the inner cavity lower limit block 52, the lower conductive sheet 12 will not slide out from the other side after being inserted. After inserting the conductive wire between the upper conductive sheet 11 and the lower conductive sheet 12, tightening the screw in the screw mounting channel 6 can fix the conductive wire. When the conductive sheet needs to be replaced, the screw in the mounting channel 6 is unscrewed, and the conductive sheet to be replaced is pulled out, so that a part of the conductive sheet can be replaced separately.
[0040] The distance between the upper cavity groove protrusion 41 provided on the inner wall of the wiring cavity 3 and the top wall of the wiring cavity 3 is greater than the thickness of the upper conductive sheet 11, and the distance between the bottom wall of the wiring cavity 3 and the lower cavity groove protrusion 42 is greater than the thickness of the lower conductive sheet 12. This allows the conductive sheet to be inserted into the wiring cavity 3.
[0041] according to Figure 2 As shown, in the utility model, two wiring terminals are connected by a ring-shaped connecting component 7, so that several wiring terminals are arranged in parallel. During use, on the one hand, the wiring terminals can be fixed on other workpieces through the circular holes in the ring-shaped connecting component 7, and on the other hand, the number of wiring terminals arranged in parallel can be reduced by cutting the ring-shaped connecting component 7 as needed; and the fixedly connected wiring terminals can fix and maintain their relative positions to each other, which is more conducive to use.
[0042] After the existing integrated internal conductive terminal block is changed to a split conductive sheet, since the structures on both sides of the integrated internal conductive terminal block are omitted, the wire that can be inserted into the wiring cavity 3 can be thicker, thereby improving the compatibility with the conductive wire; more wires can also be inserted into the wiring cavity 3, thereby expanding the application scenarios of the split conductive sheet terminal block.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
