Description

Technical Field

[0001] The utility model relates to the technical field of wiring devices, in particular to a novel wire splitter terminal. Background Art

[0002] In the fields of electric power, transportation, construction, and industrial automation, etc., the wire splitter terminal is widely used in the wiring mode of one input and multiple outputs or multiple inputs and multiple outputs. In the prior art, the conductive part generally uses a copper block, and the whole copper block is machined correspondingly to meet the wiring function. This method wastes a lot of copper materials, takes a long time to process, and has too high costs, which does not meet the requirements of today's conservation-oriented society and needs to be improved. Content of the Utility Model

[0003] To solve the above at least one technical defect, the utility model provides the following technical solutions:

[0004] This application document discloses a novel wire splitter terminal, including a housing and a conductive part. The conductive part is fixed in the cavity of the housing. On the housing wall, there are provided a first wire inlet hole and a second wire inlet hole that are communicated with the cavity of the housing. In the cavity of the housing, there are provided a first frame and a second frame. The frame opening of the first frame corresponds to the first wire inlet hole, and the frame opening of the second frame corresponds to the second wire inlet hole. A part of the conductive part is located in the cavities of the first frame and the second frame. A connecting part is provided on the housing. The first frame and the second frame are connected to the corresponding connecting parts, and the head ends of the connecting parts are exposed outside the housing. By driving the corresponding connecting parts, the corresponding first frame and second frame can be moved up and down, and synchronously, the part of the conductive part in the cavity can be made to cooperate with the corresponding cavity wall to clamp or release the inserted wire.

[0005] In this solution, the terminal structure is improved. By adjusting the positions of the corresponding first frame and second frame through the connecting part, the cavity walls of the first frame and the second frame cooperate with the corresponding conductive part in their cavities to form clamping or releasing of the wire. The split clamping structure can replace the materials of the first frame and the second frame according to requirements. This configuration helps to reduce the usage amount of copper materials, and thus reduces costs.

[0006] Regarding the positions of the second wiring hole and the first wiring hole, such as on adjacent faces, opposite faces, the same face, etc. of the housing, all are acceptable and can be selected according to needs.

[0007] Preferably, the first wire inlet hole and the second wire inlet hole are respectively located on the opposite side faces of the housing. An installation hole is provided on the top surface of the housing. The tail end of the connecting part extends into the cavity of the housing from the installation hole and is connected to the corresponding first frame and second frame, reasonably arranging the positions of the connecting part, wiring holes, etc., which is convenient for use.

[0008] Regarding the connection between the connecting part and the housing and the frame, such as the connecting part being threadedly connected or interference-fitted with the housing, etc., preferably,

[0009] First: The connecting member is of a threaded type. The connecting member is threadedly connected to the housing, and the tail end of the connecting member is rotatably connected to the corresponding first frame and second frame. The inserted wire or the cavity wall of the housing restricts the rotation of the frame. Then, the connecting member is rotated to move up and down relative to the housing, correspondingly causing the frame to move up and down to cooperate with the conductive member in the cavity to partially clamp or release the wire.

[0010] Second: The connecting member is of a threaded type. The connecting member is threadedly connected to the housing, and the tail end of the connecting member is threadedly connected to the corresponding first frame and second frame.

[0011] Third: The connecting member is of a threaded type. The connecting member is rotationally mated with the housing, and the tail end of the connecting member is threadedly connected to the corresponding first frame and second frame. The inserted wire or the cavity wall of the housing restricts the rotation of the frame. Then, the connecting member is rotated to move up and down relative to the housing, correspondingly causing the frame to move up and down to cooperate with the conductive member in the cavity to partially clamp or release the wire.

[0012] Fourth: The connecting member is in interference fit with the mounting hole formed at the housing wall. For example, if the circumferential wall of the connecting member is in interference fit with the hole wall of the mounting hole, the connecting member can be moved up and down synchronously to cause the frame to move up and down. Under the frictional force of the interference fit, the connecting member stays at the desired position, correspondingly causing the frame to stay at the predetermined position.

[0013] Further, the inner area of the housing is partitioned into multiple sub-chambers, which correspond to the first wire inlet hole and the second wire inlet hole. The first frame and the second frame are located in the corresponding sub-chambers, and the circumferential constraint is formed on the first frame or the second frame in the cavity by the cavity wall of the sub-chamber. The circumferential constraint restricts the rotation of the first frame and the second frame relative to the cavity wall, facilitating the driving of the corresponding frame to move up and down by the connecting member.

[0014] For the molding of the housing, it can be formed by assembling left and right parts, assembling upper and lower parts, etc.

[0015] Preferably, the housing includes a main body, a cover plate, and an insulating bracket. The cover plate is arranged at the cavity opening of the main body, and an insulating bracket is arranged in the cavity formed by the two. The head end of the connecting member at least extends into the mounting hole formed at the cover plate. The bracket and the cavity wall cooperate to enclose multiple sub-chambers. The insulating bracket can be installed in the cavity of the main body after being independently molded, or the bracket and the main body are integrally molded, which can be selected according to needs.

[0016] Further, the bracket includes a main board and side boards. The main board is longitudinally arranged, and the side boards are arranged at intervals along the length direction on both sides of the main board. The side boards are located in the card slots formed at the cavity wall of the main body. The main board, the side boards, and the corresponding cavity wall cooperate to enclose multiple sub-chambers. In this configuration, the bracket is convenient for cooperating with the cavity wall to enclose the required cavity, which helps to simplify the structure.

[0017] Furthermore, bumpers are provided on the cavity wall of the main body and are located above the bracket. The bracket and the bumpers cooperate to clamp the conductive member, and the conductive member is fixed in a clamping manner, facilitating assembly and molding.

[0018] Furthermore, both the first frame and the second frame are rectangular frames. The conductive member includes a main body and convex plates. The convex plates are arranged at intervals along the length direction on the opposite sides of the main body and extend into the cavity from the corresponding frame openings, facilitating assembly and molding.

[0019] Furthermore, support blocks are convexly provided at the bottom surfaces of the first frame and the second frame, which helps to limit the downward movement position of the frames.

[0020] Furthermore, both the first frame and the second frame are made of iron, reducing costs and the use of copper materials.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] 1. The present utility model improves the terminal structure. By moving the corresponding frame with a connecting member and using the cavity wall of the frame to cooperate with the conductive member to clamp or release the wire, it helps to reduce the usage amount of copper materials and lower costs.

Specific Embodiment

[0035] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Embodiment 1

[0037] As Figure 1 , Figure 2 , Figure 3 shown, in this example, the new type of wire splitting terminal includes a housing and a conductive member 7. The conductive member 7 is fixed in the cavity of the housing. The conductive member is formed by common copper materials, and of course, other required materials can also be used for forming as long as the conductive requirements are met.

[0038] The configuration of the housing can also be selected according to requirements, such as rectangular, cylindrical or other configurations, etc. In this example, a rectangular housing is taken as an example for display. On the opposite side walls of the housing, first wire inlet holes 3 and second wire inlet holes 4 communicating with the cavity of the housing are formed. For example, the first wire inlet hole 3 is connected to the first wire, and the second wire inlet hole 4 is connected to the second wire. The number of the first wire inlet hole and the second wire inlet hole can be selected according to requirements, such as single, multiple, etc. As Figure 1 , Figure 2 shown, in this example, three first wire inlet holes 3 are formed at intervals along the length direction on the left side of the housing, and four second wire inlet holes 4 are formed at intervals along the length direction on the right side. Of course, regarding the positions of the second wiring hole and the first wiring hole, they can also be on adjacent surfaces, opposite surfaces, the same surface, etc. of the housing, and are selected according to requirements.

[0039] In this example, a first frame body 8 and a second frame body 9 are arranged in the cavity of the housing. The frame opening of the first frame body 8 corresponds to the first wire inlet hole 3, and the frame opening of the second frame body 9 corresponds to the second wire inlet hole 4. The wire extends into the frame cavity of the frame body from the first wire inlet hole. Part of the conductive member 7 is in the cavities of the first frame body 8 and the second frame body 9. A connecting member 6 is arranged on the housing. For example, one connecting member 6 is connected to the first frame body 8, and the other connecting member 6 is connected to the second frame body 9, and the head end of each connecting member 6 needs to be exposed outside the housing for convenient operation.

[0040] The fitting relationship between the connecting member and the corresponding frame and the housing is as follows: Driving the corresponding connecting member 6 causes the corresponding first frame 8 and second frame 9 to move up and down, and synchronously causes a part of the conductive member 7 in the cavity to cooperate with the corresponding cavity wall to perform a clamping or releasing action on the inserted wire. Specifically, for example: The first wire extends into the cavity of the first frame through the first wire inlet hole, and a part of the conductive member is also in the cavity of the first frame. Driving the connecting member causes the first frame 8 to move upward relative to the housing as described above. The conductive member 7 is fixed to the housing and remains relatively stationary. Then, during the upward movement of the first frame 8, the bottom wall of the first frame 8 and the upper part of the conductive member 7 clamp the wire head between them, thereby fixing the first wire relative to the frame and making the wire head contact the conductive member part in the cavity of the frame to form an electrically connected state. The corresponding second wire extends into the cavity of the second frame through the second wire inlet hole. Operating the corresponding connecting member makes the wire head of the second wire contact the conductive member part in the cavity of the second frame to form an electrically connected state, so that the first wire and the second wire are in an electrically connected state.

[0041] Regarding the specific type of the connecting member, such as the threaded type, commonly seen as bolts, screws, etc. In the layout where the first wire inlet hole 3 and the second wire inlet hole 4 are located on opposite side surfaces of the housing, in this example, mounting holes 22 are formed on the top surface of the housing to connect with the connecting member 6. The mounting holes are like threaded holes. The connecting member is selected as a bolt and is threadedly connected to the mounting hole. The tail end part of the connecting member 6 extends into the cavity of the housing through the mounting hole 22 and is pivotally connected to the corresponding first frame 8 and second frame 9. The head end of the connecting member 6 is in the mounting hole 22 for convenient operation. Taking the first frame as an example, when in use, if the connecting member is turned, the connecting member 6 moves upward relative to the housing. The connecting member 6 is pivotally connected to the first frame 8. Under the limitation of the inserted first wire, the first frame does not rotate and moves upward relative to the housing, and then the bottom wall of the frame cavity and the upper part of the conductive member form a clamping action. Of course, the circumferential movement of the first frame can also be directly restricted by the cavity wall of the housing to limit its rotation to ensure the corresponding state between the frame opening and the first wire inlet hole, so as to avoid affecting the contact between the wire and the conductive member.

[0042] Of course, the mounting hole can also be selected as a through hole without threads. Taking the first frame as an example, the connecting member is like a bolt. The connecting member is pivotally connected to the mounting hole. The tail end of the connecting member extends into the cavity of the housing and is threadedly connected to the threaded hole formed on the top of the first frame. Turning the connecting member with force, the circumferential rotation of the first frame is restricted by the inserted first wire or the cavity wall of the housing (i.e., a circumferential constraint is formed). Then, under the threaded connection, the connecting member rotates to make the first frame move upward relative to the housing. During the upward movement, the bottom wall of the cavity of the first frame and the upper part of the conductive member form a clamping on the inserted wire head, and then an electrical connection is achieved.

[0043] In addition, the connecting member can be selected to have an interference fit with the mounting hole formed at the housing wall. Taking the first housing as an example, if the circumferential wall of the connecting member has an interference fit with the hole wall of the mounting hole, the tail end of the connecting member extends into the housing cavity and is fixed to the top of the first housing. When a force drives the connecting member to move upward, under the frictional force of the interference fit, it stays at the required position. During the movement of the housing relative to the housing, the bottom wall forms a clamping force on the inserted wire head with a part of the upper conductive member, thereby forming an electrical connection.

[0044] The fitting structure of the above-mentioned connecting member with the housing and the corresponding housing can be selected according to requirements.

[0045] To isolate the wires in the housing cavity and improve safety performance, as Figure 3 、 Figure 5 shown, in this example, the housing cavity is partitioned into multiple sub-chambers 5. The sub-chambers 5 are arranged in two rows to correspond to the first wire inlet hole and the second wire inlet hole one by one. The first housing 8 and the second housing 9 are located in the corresponding sub-chambers 5, and the circumferential wall of the sub-chamber forms a circumferential constraint on the first housing or the second housing in the cavity. The first housing 8 and the second housing 9 are both rectangular frame types. As Figure 9 shown in the configuration of the first housing 8, a predetermined gap is reserved between the circumferential wall of the corresponding sub-chamber 5 and the side surface of the housing or they are directly fitted to limit its circumferential rotation. Mounting holes 22 are formed at the top wall of the housing corresponding to each sub-chamber 5.

[0046] In this example, for the convenience of installing the components inside the housing cavity, an upper and lower split assembly molding is adopted. As Figure 3 、 Figure 5 、 Figure 7 、 Figure 8 shown, the housing includes a trough-shaped main body 1, a cover plate 2 and an insulating support 11. The cover plate 2 is installed at the cavity opening of the main body 1 to cooperate to enclose a cavity, and the insulating support 11 is arranged in the cavity surrounded by the two. Of course, the main body and the cover plate are also formed of insulating materials. For the fixation of the cover plate and the main body, methods such as screw fastening, fitting fixation, and snap fixation can be used. As Figure 3 、 Figure 7 、 Figure 5 shown, in this example, snap fixation is adopted. Snap catches 102 are formed on the side of the cavity opening of the main body 1, and corresponding snap holes 21 are formed on the cavity wall of the cover plate 2. When the cover plate and the main body are butted, the snap catches and the snap holes form a snap connection to be fixed as a whole. In addition, through holes 103 can be formed on the protruding plate at the bottom surface of the main body, and bolts and the like can pass through the through holes for fixation.

[0047] The support 11 and the cavity wall cooperate to enclose multiple sub-chambers 5. The insulating support 11 can be installed in the cavity of the main body 1 after being independently formed, or the support and the main body are integrally formed, which can be selected according to needs. As Figure 3 、 Figure 5As shown, in this example, the bracket 11 is installed into the main body cavity after being independently formed. The bracket 11 includes, for example, a main board 111 and side boards 112. The main board 111 is longitudinally arranged, and the side boards 112 are formed at intervals along the length direction on both sides of the main board 111. A card slot 101 for inserting the side board is formed at the cavity wall of the main body 1. During installation, the side board 112 and the notch of the card slot 101 are vertically corresponding. Press down the bracket so that the side of the side board is in the card slot to fix it. Then, as Figure 5 As shown, the main board 111, the side boards 112 and the corresponding cavity walls cooperate to enclose a plurality of sub-chambers 5. An inlet hole 1 3 or an inlet hole 2 4 is formed at the corresponding side of the main body 1 where the sub-chamber 5 is located. A frame 1 8 or a frame 2 9 is correspondingly arranged in each sub-chamber 5, and the cover plate 2 seals the cavity opening of the main body 1.

[0048] For the conductive part, such as Figure 6 , Figure 3 , Figure 4 As shown, the flat conductive part 7 includes a plate-shaped body 71 and convex plates 72. The convex plates 72 are formed at intervals along the length direction on the opposite sides of the body 71, and the convex plates 72 extend into the cavity from the corresponding frame openings. The conductive part 7 is arranged on the bracket 11, and the main board 111 of the bracket 11 supports the body 71 of the conductive part 7. The convex plates 72 of the conductive part 7 extend into the sub-chamber 5 and into the frame cavity of the corresponding frame. To facilitate the fixation of the conductive part, in this example, convex blocks 100 are formed at the cavity walls at both ends of the main body 1. The convex blocks 100 are above the main board 111. The two ends of the body 71 of the conductive part 7 are clamped between the convex blocks 100 and the main board 111 of the bracket 11. When installing the conductive part, directly press down to deform the convex blocks, and then cross over the convex blocks and be clamped between the main board and the convex blocks. In addition, a pressing plate 23 can also be formed on the cover plate 2. When the cover plate is fixed to the cavity opening of the main body, the pressing plate 23 and the main board 111 of the bracket 11 cooperate to clamp the body 71 of the conductive part 7 again.

[0049] In addition, support blocks 10 can be formed to protrude outward at the bottom surfaces of the frame 1 8 and the frame 2 9, which helps to limit the downward movement position of the frame. For the formation of the frame 1 and the frame 2, for example, they are integrally cast or bent. As Figure 9 As shown, the two ends of the strip are bent to form the frame 1 8, and one end of the strip can be embedded into the hole groove of the other end.

[0050] In this example, both the frame 1 8 and the frame 2 9 are made of iron, which helps to reduce costs and reduce the usage amount of copper materials.

[0051] The above is only the preferred implementation mode of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
