Description

Technical Field

[0001] This utility model relates to the field of electrical instrument junction boxes, specifically to an electrical instrument junction box that facilitates wiring. Background Technology

[0002] Junction boxes are electrical accessories used in circuit engineering to protect and connect wires. They are characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, no site restrictions, wide application, stable and reliable operation, high space utilization, small footprint, and environmental benefits.

[0003] For example, the public document with application number 202021842087.4 discloses an electrical instrument junction box that facilitates wiring. This utility model uses the cooperation of fixed feet, connecting structures, bolts, and the box body to pull out the cover or cover plate along with the internal component boards during wiring. At this time, all cables can be introduced for wiring operations. Compared with the traditional junction box wiring method, all internal wiring operations are completed outside the box, and the wiring operation is not restricted by the box body, thus making the wiring operation more convenient and faster. However, the cable plugs of this electrical instrument junction box are all exposed. That is, regardless of whether they are used or not, the plugs are directly exposed on the outside. For unused plugs, dust and moisture may enter the equipment through the plugs and adhere to them, thereby affecting the stability of the internal circuit of the junction box. In severe cases, it may even cause the entire junction box to become unusable, affecting the safety of use.

[0004] Therefore, in view of this, we studied and improved the existing structure to propose an electrical instrument junction box that is easy to wire. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical instrument junction box that is easy to wire, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical instrument junction box for easy wiring, comprising a box body, a sealing cover provided at the bottom of the box body, cable plugs evenly distributed through the front surface of the sealing cover, a protective shell fixedly installed on the lower surface of the sealing cover, the protective shell covering the lower end of the cable plug, partitions evenly distributed and fixedly installed on the inner surface of the protective shell, the partitions covering each cable plug in sections, and sockets evenly distributed in the middle of each area separated by the partitions on the lower surface of the protective shell, grooves being formed on the rear side of the inner surface of each socket, a spring fixedly installed on the rear side of the inner surface of the groove, and a baffle fixedly connected to one end of the spring near the opening of the groove.

[0007] Preferably, the sockets correspond one-to-one with the cable plugs, and the lower surface of the baffle is set as an inclined surface.

[0008] Preferably, a movable plate is fixedly installed on the rear side of the upper surface of the sealing cover, and sliders are fixedly installed on both the left and right sides of the upper surface of the movable plate.

[0009] Preferably, a device board is fixedly connected to the front side of the surface of the movable plate, and the device board is connected to the upper end of the cable plug using a wire harness.

[0010] Preferably, slide rails are fixedly installed on both the left and right sides of the inner surface of the box, and the slider slides inside the slide rails.

[0011] Preferably, protruding plates are fixedly installed on the lower left and right sides of the outer surface of the box, and movable buckles are rotatably installed on both the left and right ends of the surface of the sealing cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides sufficient and effective separation and protection for exposed cable plugs by setting up a protective shell, partition, socket, groove, spring and baffle. Each cable plug can be used independently, while the remaining unused cable plugs can still be in a closed protective state, thereby greatly improving the safety of the cable plugs and preventing uniform exposure, which may lead to dust or moisture adhering and damaging the junction box plug terminals.

[0014] 2. This utility model, through the setting of movable plate, slider, slide rail, convex plate and movable buckle, allows the wiring work of the component board to be carried out on the outside of the box. The external space of the box is not limited by the size of the box itself, making it more convenient for manual wiring operations, thereby greatly improving the convenience of connecting the internal circuit of the box and significantly improving the wiring work efficiency.

[0019] 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.

[0020] like Figures 1-3 As shown, an electrical instrument junction box for easy wiring includes a box body 1. A sealing cover 2 is provided at the bottom of the box body 1. Cable plugs 3 are evenly distributed and penetrated on the front side of the surface of the sealing cover 2. A protective shell 4 is fixedly installed on the lower surface of the sealing cover 2, and the protective shell 4 covers the lower end of the cable plugs 3. A partition 401 is evenly distributed and fixedly installed on the inner surface of the protective shell 4, and the partition 401 covers each cable plug 3 in sections. Sockets 5 are evenly distributed in the middle of each area separated by the partition 401 on the lower surface of the protective shell 4. A groove 6 is provided on the rear side of the inner surface of each socket 5. A spring 7 is fixedly installed on the rear side of the inner surface of the groove 6. A baffle 8 is fixedly connected to one end of the spring 7 near the opening of the groove 6.

[0021] By adopting the above technical solution, the protective shell 4 covers the exposed cable plug 3 at the lower end, thereby preventing the cable plug 3 from being directly exposed and providing effective protection for the cable plug 3.

[0022] The partition 401 divides the cable plug 3 into sections for protection inside the protective shell 4, so that each cable plug 3 will not come into contact with each other. Even if one cable plug 3 is used, the other cable plugs 3 will still be stored separately in a closed protective state.

[0023] The cable can be inserted into the protective housing 4 through the socket 5 and connected to the corresponding cable plug 3;

[0024] Under normal conditions, the spring 7 pushes the baffle 8 to close the socket 5, thereby ensuring that each cable plug 3 can be sealed and protected inside the protective shell 4. When the baffle 8 pushes the spring 7 to retract into the groove 6, the socket 5 can be opened, thereby ensuring the normal connection between the cable and the cable plug 3.

[0025] Furthermore, the socket 5 corresponds one-to-one with the cable plug 3, and the lower surface of the baffle 8 is set as an inclined surface.

[0026] By adopting the above technical solution, when the cable is inserted into the socket 5, the inclined surface can be used to directly push the baffle 8 to retract, eliminating the need for manual movement of the baffle 8 and improving the convenience of connecting the cable.

[0027] Furthermore, a movable plate 9 is fixedly installed on the rear side of the upper surface of the sealing cover 2, and sliders 11 are fixedly installed on both the left and right sides of the upper surface of the movable plate 9; slide rails 12 are fixedly installed on both the left and right sides of the inner surface of the box 1, and the sliders 11 slide inside the slide rails 12.

[0028] By adopting the above technical solution, the movable plate 9 can move stably up and down by sliding the slider 11 in the slide rail 12.

[0029] Furthermore, a device board 10 is fixedly connected to the front side of the surface of the movable plate 9, and the device board 10 is connected to the upper end of the cable plug 3 via a wire harness.

[0030] By adopting the above technical solution, when the movable plate 9 moves down and extends out of the box 1, it will drive the component board 10 to move out of the box 1, and the component board 10 can be wired on the outside of the box 1. The external space of the box 1 is not limited by the size of the box 1 itself, making it more convenient for manual wiring operations.

[0031] Furthermore, protruding plates 13 are fixedly installed on the lower left and right sides of the outer surface of the box 1, and movable buckles 14 are rotatably installed on both the left and right ends of the surface of the sealing cover 2.

[0032] By adopting the above technical solution, the sealing cover 2 is pushed up to close the bottom of the box 1, and the movable buckle 14 is rotated and fastened to the surface of the protruding plate 13, so that the sealing cover 2 is fixed to the box 1. At this time, the movable plate 9 can be stably stored inside the box 1.

[0033] After disassembling the movable buckle 14 and the protruding plate 13, the movable plate 9 can move freely up and down.

[0034] Working principle: When using this easy-to-wire electrical instrument junction box, firstly, rotate the movable buckle 14 to disengage from the protruding plate 13. At this time, the sealing cover 2 is released from the box body 1. The movable plate 9 moves steadily downward along the slide rail 12 via the slider 11, carrying the component plate 10 out of the box body 1. The operator manually connects the component plate 10 to the cable plug 3 and electrical components outside the box body 1. After the wiring is completed, push the sealing cover 2 to move the movable plate 9 carrying the component plate 10 upward and retract it into the box body 1. Rotate the movable buckle 14 again to engage with the protruding plate 13. The interface fixes the sealing cover 2 to the box body 1, forming a complete box body 1. Then, the protective shell 4 holds the cable plug... The lower end of the head 3 is covered for protection, preventing the cable plug 3 from being completely exposed. When the cable plug 3 is to be used to connect a cable, the corresponding socket 5 is located and the cable is inserted. The cable uses its end to push the baffle 8 through the inclined surface to compress the spring 7 and retract into the groove 6, thereby opening the socket 5. At this time, the cable can be smoothly connected to the cable plug 3. At this time, other unused cable plugs 3 are blocked by the partition 401 and stored separately in an independent area inside the protective shell 4. They are not connected to each other. Under the action of the spring 7, the baffle 8 will close the socket 5, thereby sealing and protecting the unused cable plugs 3. This is the working principle of this electrical instrument junction box that facilitates wiring.
