Technical Field

[0001] This utility model relates to the field of junction box technology, and specifically to a quick-connect junction box. Background Technology

[0002] A junction box is an electrical connection device used for grounding power supplies, cables, and wires, and it also serves as insulation to prevent short circuits and leakage. There are various types of junction boxes, which can be classified according to their functions as general type, plug-in type, splash-proof type, explosion-proof type, photovoltaic type, sensor type, electricity meter type, etc., designed according to different usage environments and functional requirements.

[0003] In applications involving installation or maintenance, such as lighting fixtures, sensors, industrial equipment, and modular devices, pluggable junction boxes are required. These boxes connect via male-female pairing. However, traditional pluggable junction boxes connect only through friction between terminals, similar to the connection between a plug and a socket. While this connection method is simple, it is prone to loosening under vibration or high temperature conditions, leading to circuit interruptions or poor contact, thus affecting the normal operation of the equipment.

[0004] Currently, a utility model patent with announcement number CN214069724U discloses a junction box. This patent uses bolts to fix the junction box, which can effectively prevent loosening and thus improve the reliability of the product. The positive and negative input terminals can be connected to the socket holes of the docking socket, so that the circuit can be connected.

[0005] The connection method between the junction box and the socket in the above technical solution is the same as that in the prior art, which is to connect by friction. If bolts are added for fixing, the installation and disassembly process will be more cumbersome and less convenient. In this regard, this application provides a quick-connect junction box to solve the above problems. Utility Model Content

[0006] Based on the above description, this utility model provides a quick-connect junction box to solve the problem that plug-in junction boxes in the prior art are prone to loosening due to vibration or high temperature.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A quick-connect junction box includes a box cover, a base and a female seat, wherein a connector is provided between the box cover and the base, and a first insertion end and a second insertion end are provided at the bottom of the base; The base is provided with a wiring module for cable connection and a limiting module with elastic deformation capability. The limiting module is located at the bottom of the base and includes three limiting parts and one auxiliary part. The female base has a docking groove and three rectangular grooves. The docking groove is for the first insertion end and the second insertion end to be inserted. The rectangular grooves are connected to the inside of the docking groove and are for the limiting member to be inserted and limited.

[0008] The above technical solution allows the cover and base to be connected via a connector for easy opening and closing; a wiring module allows for cable connection; and the combination of a limiting component and a rectangular groove enables the base and the female connector to be locked in place, ensuring good stability and preventing loosening.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the limiting member is an L-shaped limiting piece that can undergo elastic deformation and reset. Three limiting pieces are respectively provided on both sides of the second insertion end and on the outside of the first insertion end. The outer side of the limiting piece has a limiting protrusion, and the top of the limiting protrusion is arc-shaped.

[0011] The above technical solution enables the limiting piece to undergo elastic deformation, causing it to bend to a certain extent, and it can be reset.

[0012] Furthermore, the rectangular groove is for the corresponding limiting piece and limiting protrusion to be inserted, and the rectangular groove is provided with a mating protrusion, the bottom of which is arc-shaped; The three limiting protrusions correspond to the positions of the three mating protrusions, and the limiting protrusions can be moved to the bottom of the corresponding mating protrusions.

[0013] The above technical solution allows the mating protrusion to limit the positioning protrusion, and the arc-shaped design allows the positioning protrusion to easily detach from the rectangular groove.

[0014] Furthermore, the mating groove includes a first slot and a second slot formed on the female seat. The first slot and the second slot are connected to the interior of the rectangular groove. The first slot is for the first insertion end to be inserted, and the second slot is for the second insertion end to be inserted.

[0015] The above technical solution allows the first insertion end and the second insertion end to be inserted into the inner side of the first slot and the second slot, respectively.

[0016] Furthermore, four ribs are provided between the outer side of the first insertion end and the bottom of the base, and four connecting slots are provided on the female seat for the four ribs to be inserted into, and the connecting slots are connected to the interior of the first slot.

[0017] By using the above technical solution, the rib plate can increase the stability of the structure without affecting the normal insertion action of the first insertion end.

[0018] Furthermore, the wiring module includes three wiring terminals on the base, and the base has fixing holes for the three wiring terminals to pass through and be fixed, wherein two wiring terminals are located inside the first insertion end; Another terminal is located inside the second insertion end and is connected to a grounding plate at the top.

[0019] Through the above technical solutions, the terminal block can be used for cable connection and current transmission; the grounding plate can provide circuit protection; and the mating end can work with the terminal block to transmit current.

[0020] Furthermore, an inlet is provided between the outer side of the box cover and the base, and one side of the box cover is rotatably connected to the top of the base via a pivot. The connecting component includes two limiting paddles located on the side of the box cover away from the pivot and having elastic deformation and reset capabilities, as well as two limiting frames located on the outer side of the base. The outer side of the limiting lever is provided with a protrusion, and the top and bottom of the limiting frame are both open. The two limiting frames are respectively for the two limiting levers to be inserted into, and the protrusion can abut against the bottom of the corresponding limiting frame.

[0021] Through the above technical solution, the protrusion and the bottom of the limiting frame can achieve the effect of locking and limiting.

[0022] Furthermore, the auxiliary component includes a connecting rod located at the bottom of the base, and three limiting plates with elastic deformation and reset capabilities are provided on the outside of the connecting rod, forming a V-shape between the limiting plates and the connecting rod.

[0023] The above technical solution enables the limiting piece to undergo a certain degree of elastic deformation, thus fulfilling its locking and limiting function.

[0024] Furthermore, the female seat is provided with a circular groove for the connecting rod and the limiting piece to be inserted. The circular groove consists of an opening groove on the top of the female seat and a receiving cavity inside the female seat. The opening groove and the receiving cavity are connected.

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

The bottom of the base 2 is provided with a first insertion end 22 and a second insertion end 23. The base 2 is provided with a wiring module 4 for cable connection and a limiting module 5 with elastic deformation capability. The limiting module 5 is located at the bottom of the base 2 and includes three limiting members and an auxiliary member. The female connector 3 is provided with a mating groove and three rectangular grooves 33. The mating groove is for the first insertion end 22 and the second insertion end 23 to be inserted. The rectangular grooves 33 are connected to the interior of the mating groove and are for the limiting members to be inserted and limited.

[0032] It should be noted that the above structures are all made of heat-resistant and insulating plastic, which can meet the usage requirements of junction boxes.

[0033] refer to Figure 2 and Figure 5 The limiting member is an L-shaped limiting piece 51 that can undergo elastic deformation and reset. It can be a plastic piece. The three limiting pieces 51 are respectively located on both sides of the second insertion end 23 and on the outside of the first insertion end 22. The outer side of the limiting piece 51 has a limiting protrusion. The top of the limiting protrusion is arc-shaped, which allows the limiting piece 51 to undergo elastic deformation, causing it to bend to a certain extent and reset, thereby achieving the effect of locking and releasing the limiting.

[0034] refer to Figure 5 The rectangular groove 33 provides a corresponding limiting piece 51 and a limiting protrusion for insertion. The rectangular groove 33 is provided with a mating protrusion, the bottom of which is arc-shaped. The three limiting protrusions correspond to the positions of the three mating protrusions respectively. The limiting protrusions can be moved to the bottom of the corresponding mating protrusion, so that the mating protrusion can abut and limit the limiting protrusion, thus restricting the limiting piece 51 to the inner side of the corresponding rectangular groove 33. Furthermore, due to the arc-shaped design, the limiting protrusions can be easily disengaged from the rectangular groove 33 by pulling them out.

[0035] refer to Figure 4The mating groove includes a first slot 31 and a second slot 32 formed on the female seat 3. The first slot 31 and the second slot 32 are connected to the interior of the rectangular groove 33. The first slot 31 is for the first insertion end 22 to be inserted, and the second slot 32 is for the second insertion end 23 to be inserted, so that the first insertion end 22 and the second insertion end 23 can be inserted into the inner side of the first slot 31 and the second slot 32 respectively.

[0036] refer to Figure 2 Four ribs 24 are provided between the outer side of the first insertion end 22 and the bottom of the base 2. The female base 3 is provided with four connecting slots for the four ribs 24 to be inserted. The connecting slots are connected to the inside of the first slot 31. The ribs 24 can increase the stability of the structure and will not affect the normal insertion action of the first insertion end 22.

[0037] refer to Figure 3 and Figure 5 The wiring module 4 includes three terminals 41 mounted on the base 2. The base 2 has fixing holes for the three terminals to pass through and be fixed. Two terminals 41 are located in the first insertion end 22, and the cables connected to the two terminals 41 are the positive and negative terminals, respectively, so that they can transmit current. The other terminal 41 is located in the second insertion end 23, and a grounding plate 42 is connected to its top, so that it can act as a grounding wire. The grounding plate 42 can provide circuit protection. The bottoms of the first insertion end 22 and the second insertion end 23 are both open. The first slot 31 and the second slot 32 are provided with mating ends for the corresponding terminals 41 to be inserted. The mating ends can cooperate with the terminals 41 to transmit current. The cooperation between the terminals 41 and the mating ends is an existing electrical connection technology, so it will not be described in detail.

[0038] refer to Figure 2 and Figure 3 A cable inlet 43 is provided between the outer side of the cover 1 and the base 2. The cable inlet 43 is for cable to pass through and be arranged. One side of the cover 1 is rotatably connected to the top of the base 2 via a pivot, so that the cover 1 can rotate. The connecting parts include two limiting paddles 11 located on the side of the cover 1 away from the pivot and having elastic deformation and reset capabilities, and two limiting frames 21 located on the outer side of the base 2. The outer side of the limiting paddles 11 has a protrusion. The top and bottom of the limiting frames 21 are open. The two limiting frames 21 are respectively for the two limiting paddles 11 to be inserted. The protrusion can abut against the bottom of the corresponding limiting frame 21. The limiting of the protrusion and the bottom of the limiting frame 21 can play a locking and limiting effect, and can be easily removed under the action of elastic deformation and reset.

[0039] refer to Figure 6 and Figure 7The auxiliary component includes a connecting rod 52 located at the bottom of the base 2. Three limiting pieces 53 with elastic deformation and reset capability are provided on the outside of the connecting rod 52. The limiting pieces 53 and the connecting rod 52 form a V-shape, so that the limiting pieces 53 can undergo a certain elastic deformation, so that they can meet the function of locking and limiting.

[0040] refer to Figure 7 The female seat 3 has a circular groove 34 for inserting the connecting rod 52 and the limiting piece 53. The circular groove 34 consists of an opening groove on the top of the female seat 3 and a receiving cavity inside the female seat 3. The opening groove and the receiving cavity are connected, so that the connecting rod 52 and the limiting piece 53 can normally enter the inner side of the circular groove 34. The inner diameter of the opening groove is smaller than the inner diameter of the receiving cavity. The connection between the opening groove and the receiving cavity is arc-shaped. The outer side of the limiting piece 53 is arc-shaped. The top of the limiting piece 53 can abut against the bottom of the opening groove, so that the limiting piece 53 can be limited by the circular groove 34. Under the arc-shaped limitation, it will not actively detach without human intervention, thus achieving the effect of preventing detachment.

[0041] In use, connect the positive and negative terminals and the ground cable to the corresponding terminals 41 respectively to complete the assembly. Then press the cover 1 so that the limiting piece 51 is inserted into the inner side of the corresponding rectangular groove 33 and the limiting piece 53 is inserted into the inner side of the corresponding circular groove 34 and is limited by it. Under the snap-fit ​​limiting, the connection stability can be met, preventing loosening due to vibration or high temperature.
