Description

Technical Field

[0001] This utility model relates to the field of terminal technology, specifically to a multi-unit terminal box. Background Technology

[0002] In electrical systems, multi-unit terminal boxes are key components for achieving electrical connections and are widely used in power transmission, electronic equipment, and other fields. They undertake important functions such as connecting wires, distributing electrical energy, and transmitting signals, and their performance directly affects the safety and stability of the entire electrical system.

[0003] Currently, multi-unit terminal boxes on the market have many problems. Some terminal boxes have complex structures, which not only increase the number of parts during manufacturing but also increase assembly difficulty, leading to high production costs. Furthermore, existing terminal box wiring methods are cumbersome, affecting construction efficiency. In addition, most terminal boxes lack sufficient clamping force when tightening wires, and the clamping force cannot be adjusted. Therefore, there is an urgent need for a multi-unit terminal box with a simple structure, low cost, convenient wiring, and adjustable clamping force to meet practical application requirements. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a multi-unit terminal box.

[0005] The technical solution adopted by this utility model is: a multi-unit terminal box, comprising:

[0006] An insulating base is provided with two rows of terminal slots spaced apart on both sides. The terminal slots in the front and rear rows are equally spaced along the length of the insulating base. An installation through slot is provided at the bottom between the terminal slots in the front row and the terminal slots in the rear row.

[0007] The conductive spring includes a fixing part connected to the mounting slot, a wave-structured elastic part, and a wiring part connected to the elastic part. The wiring part is located in the terminal slot, and a deformation space is left between the wiring part and the bottom wall of the terminal slot.

[0008] An arched bracket is detachably connected to the terminal slot and covers the wiring part. A screw hole is provided on the arched bracket located above the wiring part.

[0009] A preload component, comprising a preload bolt threadedly connected to a screw hole and a clamping part rotatably connected to the top of the preload bolt.

[0010] Furthermore, the arched bracket includes a horizontal plate, side plates fixed on both sides of the horizontal plate, and wedge-shaped sliders disposed on the side plates. Sliding grooves for sliding engagement of the wedge-shaped sliders are provided on the side walls of the terminal slot.

[0011] Furthermore, the screw hole is located in the middle of the horizontal plate, and a thickened part is provided on the horizontal plate where the screw hole is located.

[0012] Furthermore, the clamping part is provided with a "T"-shaped head, and the top of the pre-tightening bolt is provided with a "T"-shaped hole that rotates with the "T"-shaped head.

[0013] Furthermore, a contact step is provided above the wiring part, an arc-shaped groove is provided on the contact step, and an arc-shaped protrusion that matches the arc-shaped groove is provided on the pressing part.

[0014] Furthermore, the two ends of the fixing part are provided with positioning steps to prevent the conductive spring from sliding out of the mounting groove.

[0015] The beneficial effects of this utility model are:

[0016] First, two rows of equally spaced terminal slots are set on both sides of the insulating base, and an installation through slot is set between the front and rear rows of terminal slots. This design makes the overall structure neat and orderly. Compared with the traditional complex terminal box structure, the component layout is more reasonable, reducing unnecessary structural parts, reducing the assembly difficulty in the manufacturing process, and effectively controlling production costs and improving production efficiency.

[0017] Secondly, the fixing part of the conductive spring is fixedly connected to the mounting slot, and the corrugated elastic part can generate large elastic deformation, thereby providing sufficient elastic clamping force for the wiring part. When the wire is connected to the wiring part in the terminal slot, the elastic potential energy of the elastic part is converted into pressure on the wiring part, making the wiring part and the wire in close contact, improving the stability of the wiring and effectively avoiding electrical faults caused by poor contact; at the same time, the deformation space left between the wiring part and the bottom wall of the terminal slot allows the wire to be pulled out without loosening the pre-tightening bolts during disassembly, making disassembly convenient.

[0018] Furthermore, the arched bracket is detachably connected to the terminal slot and covers the wiring section. Combined with the pre-tightening element, this further enhances wiring convenience and stability. During wiring, rotating the pre-tightening bolt moves the clamping part downwards, firmly pressing the wire onto the wiring section. The clamping force can be adjusted according to the working conditions, making it particularly suitable for use in situations where locking is not required, such as during debugging.

[0019] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0028] This utility model provides a multi-connector terminal box.

[0029] In this embodiment, refer to Figure 1-4 The multi-unit terminal box includes:

[0030] An insulating base 1 has two rows of terminal slots 2 spaced apart on both sides. The terminal slots 2 in the front and rear rows are equally spaced along the length of the insulating base. An installation through slot 3 is provided at the bottom between the terminal slots 2 in the front row and the terminal slots 2 in the rear row.

[0031] The conductive spring 4 includes a fixing part 5 connected to the mounting slot, a wave-structured elastic part 6, and a wiring part 7 connected to the elastic part. The wiring part is located in the terminal slot, and a deformation space 8 is left between the wiring part and the bottom wall of the terminal slot.

[0032] An arched bracket 9 is detachably connected to the terminal slot and covers the wiring part. A screw hole 10 is provided on the arched bracket located above the wiring part.

[0033] The pre-tightening component includes a pre-tightening bolt 11 threadedly connected to a screw hole and a clamping part 12 rotatably connected to the top of the pre-tightening bolt.

[0034] In the above technical solution, the insulating base provides basic support and insulation; the two rows of terminal slots facilitate orderly wiring arrangement; the mounting slot provides installation space for the conductive spring fixing part; the conductive spring is fixedly connected to the mounting slot through the fixing part; the wave structure of the elastic part gives it good elasticity, which can generate elastic deformation to provide clamping force; the wiring part is used to connect the wire, and the reserved deformation space ensures the elastic deformation of the elastic part, increasing the clamping force of the wiring part; the arched bracket is detachably connected in the terminal slot; the pre-tightening member, through the cooperation of the pre-tightening bolt and the screw hole, clamps the wire between the clamping part and the wiring part. By adjusting the pre-tightening member, the clamping force between the clamping part and the wiring part can be adjusted.

[0035] Specifically, the arched bracket includes a horizontal plate 13, side plates 14 fixed on both sides of the horizontal plate 13, and wedge-shaped sliders 15 disposed on the side plates. The side walls of the terminal slot are provided with sliding grooves 16 for sliding engagement of the wedge-shaped sliders.

[0036] In this embodiment, the horizontal plate of the arched bracket is provided with screw holes, and the side plate and the wedge-shaped slider provide structural support and positioning functions for the whole. The wedge-shaped slider slides in conjunction with the sliding groove on the side wall of the terminal slot, and the guiding and frictional force of the wedge structure are used to realize the detachable connection of the arched bracket in the terminal slot.

[0037] Specifically, the screw hole is located in the middle of the horizontal plate, and a thickened part 17 is provided on the horizontal plate where the screw hole is located.

[0038] In this embodiment, a screw hole is provided in the middle of the horizontal plate, and a thickened part is provided at the screw hole because when the pre-tightening bolt is tightened, the screw hole will bear a large axial force. The thickened part can increase the strength and thickness of the horizontal plate at the screw hole, distribute the force, and prevent the horizontal plate from being damaged due to excessive force.

[0039] Specifically, the clamping part is provided with a "T" head 18, and the top of the pre-tightening bolt is provided with a "T" hole 19 that rotates with the "T" head.

[0040] In this embodiment, the "T"-shaped head on the clamping part rotates with the "T"-shaped hole on the top of the pre-tightening bolt, so that when the pre-tightening bolt rotates, the clamping part will not rotate with it, but will only move axially, thereby achieving the clamping operation on the wire.

[0041] Specifically, a contact step 20 is provided above the wiring part, an arc-shaped groove 21 is provided on the contact step, and an arc-shaped protrusion 22 that matches the arc-shaped groove is provided on the pressing part.

[0042] In this embodiment, the contact step and arc-shaped groove above the wiring part are adapted to the arc-shaped protrusion on the clamping part. When the pre-tightening bolt drives the clamping part to move downward, the arc-shaped protrusion is embedded in the arc-shaped groove, which can limit and clamp the wire, thereby improving the stability of the wire connection.

[0043] Specifically, the two ends of the fixing part are provided with positioning steps 23 to prevent the conductive spring from sliding out of the mounting groove.

[0044] In this embodiment, the positioning steps at both ends of the fixing part are engaged with both sides of the mounting groove. The blocking effect of the steps restricts the sliding of the conductive spring in the mounting groove, ensuring the accuracy and stability of the installation position of the conductive spring.

[0045] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
