Description

Technical Field

[0001] This utility model relates to the field of electrical connection equipment technology, specifically to a junction box for multi-directional wire harness conversion. Background Technology

[0002] In many fields such as electrical control, communication equipment, automotive wiring harnesses, and household appliances, junction boxes, as a basic electrical auxiliary device, are widely used for centralized connection, transfer, distribution, and safety protection of wiring harnesses. Their core function is to provide a structured space for the termination of wires and cables, ensuring reliable, orderly, and safe electrical connections.

[0003] Currently, most common junction boxes on the market adopt a one-piece molded structure, with an internal single, undivided cavity. Wiring harnesses are introduced through several pre-drilled holes on the side wall of the box, and all terminals are centrally mounted on the same mounting plate or directly fixed to the inner wall of the cavity. While this allows for wiring harness installation, the internal capacity is fixed at the factory and cannot be flexibly adjusted according to the phased increase or change in the number of wiring harnesses in actual projects. When facing expansion needs, users often have no choice but to replace the entire junction box with a larger one, leading to increased costs and wasted resources. The one-piece structure also makes the installation, replacement, and wiring harness organization of internal components extremely inconvenient and easily affected by fixed opening positions, making it difficult to adapt to complex equipment layouts.

[0004] Therefore, in order to address the shortcomings of existing junction boxes in terms of flexibility, scalability, maintainability, and space adaptability, developing a new modular junction box structure has become a technical problem that urgently needs to be solved by those skilled in the art.

[0005] To address the technical deficiencies in the background technology, this utility model proposes a patch panel for multi-directional wire harness conversion, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: A patch panel for multi-directional wire harness conversion includes a transparent box body with an inner cavity and a transparent cover that cooperates therewith. The box body is composed of at least two independent wiring units stacked together. Each wiring unit includes an annular unit frame. At least two opposite side walls of the unit frame are provided with wire harness inlets. Adjacent wiring units are fixed together by a detachable connection structure, so that the inner cavity is divided into multiple independent wiring compartments in the vertical stacking direction.

[0006] As a further technical solution of this utility model, the connection structure includes a groove on the upper end face and a protrusion on the lower end face of the unit frame. The protrusion is engaged with the groove of the adjacent unit. The corner of the unit frame is provided with a second fastening hole and a fastener.

[0007] As a further technical solution of this utility model, each of the wiring compartments is provided with an independent terminal mounting plate, and at least one set of wiring terminals is fixed on the terminal mounting plate. The position of the wire harness inlet corresponds to the wiring direction of the wiring terminals.

[0008] As a further technical solution of this utility model, the terminal mounting plate is slidably disposed within the unit frame by means of the cooperation of slide rails fixed on both sides of the unit frame where no wire harness inlet is provided and sliders fixed on the side of the terminal mounting plate.

[0009] As a further technical solution of this utility model, the terminal mounting plate also integrates a signal indicator light and a fuse holder, and the signal indicator light is electrically connected to the corresponding wiring terminal.

[0010] As a further technical solution of this utility model, a fastening mechanism is slidably connected at the wire harness inlet. The fastening mechanism includes two semi-circular clamps and a baffle plate fixedly connected to the clamps. A first fastening hole is provided on the clamps.

Detailed Implementation

[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0017] like Figures 1 to 5 As shown, the wiring box of this utility model embodiment includes a transparent box body 1 and a transparent box cover 2. The box body and the box cover are preferably made of transparent plastic to allow for better observation of the internal situation. The box body 1 has an inner cavity, and the box cover 2 is fitted to the box body 1 by means of hinges or other means to close the inner cavity. The box body 1 is composed of at least two independent wiring units 7 stacked together. Each wiring unit 7 is a ring structure, and adjacent wiring units are fixed together by a detachable connection structure 8 to form a wiring compartment 73.

[0018] like Figures 1 to 5 As shown, the connection structure 8 includes a groove 81 on the upper end face of the unit frame 71 and a protrusion 82 on the lower end face. The protrusion 82 engages with the groove 81 of the adjacent unit. The corners of the unit frame 71 are provided with second fastening holes 83 and fasteners 84 (such as screws or bolts). By tightening the fasteners 84, adjacent unit frames 71 are securely connected. This connection method ensures the stability and sealing of the stack, while facilitating disassembly and reassembly. Furthermore, the modular design allows users to flexibly adjust the number of wiring units according to the number of wire harnesses, facilitating maintenance and expansion.

[0019] like Figures 1 to 5As shown, the wiring unit 7 includes a ring-shaped unit frame 71, which is made of transparent insulating material, preferably engineering plastic, to improve the safety of the device and provide sufficient mechanical strength. At least two opposite sidewalls of the unit frame 71 are provided with wire harness inlets 72 for introducing and withdrawing wire harnesses. The wire harness inlets 72 have a relatively large diameter, allowing for direct insertion into the device during routine simple inspections or maintenance, with sufficient operating space, making routine inspections and maintenance more convenient and efficient. Furthermore, the design of multiple wire harness inlets 72 allows for simultaneous connection of wire harnesses from multiple directions into the junction box, broadening its applicability.

[0020] like Figures 1 to 5 As shown, each wiring compartment 73 is provided with an independent terminal mounting plate 3. At least one set of wiring terminals 4 are fixed on the terminal mounting plate 3. The position of the wire harness inlet 72 corresponds to the wiring direction of the wiring terminal 4, which enables the wire harness extending into the wiring compartment 73 to be directly connected to the wiring terminal 4. This reduces the bending and crossing of the wire harness inside the wiring compartment 73, which not only facilitates installation but also reduces the stress on the wire harness, extends the service life of the wire harness, and makes the arrangement of the wire harness inside the wiring compartment 73 neater.

[0021] Furthermore, based on the above embodiment, sliders 31 are provided on both sides of the terminal mounting plate 3, and slide rails 75 are provided on both sides of the unit frame 71 where the wire harness inlet 72 is not provided. The terminal mounting plate 3 is slidably fixed inside the wiring compartment 73 through the cooperation between the sliders 31 and the slide rails 75. Due to the presence of the sliders 31 and the slide rails 75, the terminal mounting plate 3 can be easily pulled out of the wiring compartment 73 for maintenance during routine maintenance, making maintenance more convenient and safer.

[0022] like Figures 1 to 5 As shown, the terminal mounting plate 3 also integrates a signal indicator light 32 and a fuse holder 33. The signal indicator light 32 preferably uses an LED light. The signal indicator light 32 is electrically connected to the corresponding terminal 4. During normal use, it can display whether the connection status of the terminal 4 is normal, making daily inspection and maintenance more convenient and quick. At the same time, the presence of the fuse holder 33 provides overcurrent protection for the circuit and can enhance the safety of the device.

[0023] A fastening mechanism 5 is slidably connected to the wire harness inlet 72. This slidable connection is achieved through the cooperation of a slide rail and a slider. The fastening mechanism 5 includes two semi-circular clamps 51 and a baffle plate 52 fixedly connected to the clamps 51. Each clamp 51 has a first fastening hole 53. After the wire harness passes through the inlet 72, the wire harness is clamped by the sliding clamps 51, and the two clamps 51 are tightly fixed together using bolts or cable ties. This ensures the wire harness is firmly fixed at this location, reducing the impact of vibration on the wire harness and protecting the circuit. Simultaneously, the slidable design allows the fastening mechanism 5 to be adjusted according to the diameter of the wire harness, increasing the practicality of the device. The presence of the baffle plate 52 allows the fastening mechanism 5 to block the wire harness inlet after fixing the wire harness, preventing dust or foreign objects from entering the device.

[0024] like Figures 1 to 5 As shown, the unit frame 71 has heat dissipation holes 74 on both sides of the wire harness inlet 72. The heat dissipation holes 74 are multiple circular or strip-shaped holes, which can accelerate the air circulation in the wiring compartment 73 to achieve the purpose of heat dissipation.

[0025] like Figures 1 to 5 As shown, a rotatable mounting base 6 is located at the bottom of the lowest wiring unit 7. The mounting base 6 includes a fixed base 61 and a rotating base 62. The rotating base 62 is fixed to the upper end of the fixed base 61 via a rotating shaft, allowing the rotating base 62 to rotate relative to the fixed base 61. The lowest wiring unit 7 is fixedly connected to the rotating base 62 with screws. The fixed base 61 has multiple mounting holes 63 for fixing the junction box to a wall or equipment. This rotating design allows users to adjust the orientation of the junction box, facilitating the introduction of wires from different angles and improving installation flexibility.

[0026] In practical use, the user first selects an appropriate number of wiring units 7 according to the number of wire harnesses, stacks and fixes the wiring units using the connecting structure 8, then fixes the wiring box in a suitable position, rotates it to achieve the appropriate angle, and then slides the terminal mounting plate 3 into the slide rail 75 of the wiring unit 7 and connects it to the terminal 4. The wire harness is then introduced from the wire harness inlet 72, connected to the terminal 4, and fixed using the fastening mechanism 5. During routine inspection and maintenance, the internal status of the wiring box can be directly observed through the transparent box. The presence of the indicator light 32 allows the user to more easily see the wiring connection status. When maintenance is needed, it can be performed directly through the wire harness inlet 72, or by pulling the terminal mounting plate 3 out of the wiring compartment.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
