[0002] In modern electronic devices, connection modules play a crucial role as key components connecting various conductive elements. Existing connection modules typically use switches or buttons to toggle between on and off states, but these modules pose a risk of accidental activation during use. Utility Model Content

[0003] The purpose of this utility model is to provide a connection module that solves the technical problem of accidental activation when using switches or buttons in the form of existing connection modules.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A connection module includes an insulating upper housing and an insulating lower housing. The upper housing is disposed above the lower housing. A movable rod is disposed on the bottom surface of the upper housing. Two strip-shaped conductors are disposed within the inner cavity of the upper housing, with both ends of each conductor bent downwards to form conductive ends. The inner cavity of the lower housing contains a first conduit and four second conduits, all extending downwards to the lower side of the lower housing. The first conduit is disposed in the middle of the inner cavity of the lower housing, and the four second conduits are respectively disposed corresponding to the conductive ends. The channels are configured with cavities. The lower end of the movable rod passes downward through the first pipe. The movable rod and the first pipe form a sliding pair along their length. A limiting ring is fixedly sleeved on the lower end of the movable rod. A spring is installed inside the first pipe and is sleeved on the outer periphery of the movable rod. A retaining ring is fixedly installed on the upper part of the first pipe. The spring is positioned between the retaining ring and the limiting ring. The spring biases the upper housing downward. Each of the second pipes is connected to a power-conducting component. The four conductive ends extend into the four second pipes and are each connected to a power-conducting component.

[0006] Furthermore, the lower outer periphery of any one of the second pipes is provided with an external thread; the energizing assembly includes a sleeve, a limiting nut, a washer, and a screw. The sleeve is tubular, and the upper end of the sleeve is provided with several clamps along the circumferential direction. The inner wall of the sleeve is provided with an internal thread, and the middle part of the sleeve protrudes outward along the circumferential direction to form a convex ring. The sleeve extends into the second pipe. The lower end of the limiting nut is provided with a limiting ring. The limiting nut is threadedly connected to the lower part of the second pipe. The limiting ring is located on the lower side of the convex ring. The screw is threadedly connected to the internal thread of the sleeve. A washer is provided between the screw and the sleeve. The conductive end extends into the sleeve.

[0007] Furthermore, an insulating baffle is provided on the lower side of the lower housing, and the first pipe and the four second pipes all pass downward through the insulating baffle.

[0008] Furthermore, the four conductive ends are arranged along a rectangle.

[0009] Furthermore, the side of the upper housing protrudes outward to form a grip handle.

[0010] Furthermore, a dust cover is provided on the top of the upper housing.

[0011] Furthermore, the lower end of the movable rod is connected to the limiting ring via a snap-fit ​​structure.

[0012] Furthermore, the lower housing has a test hole and a reserved groove on its side wall, and the test hole is connected to the second pipe.

[0013] Working principle:

[0014] This invention includes an upper housing and a lower housing. A movable rod is located at the bottom of the upper housing, extending into the first pipe of the lower housing. A spring is installed around the outer periphery of the movable rod, ensuring that the upper housing is always subjected to a pulling force towards the lower housing. This guarantees that the connection between the upper and lower housings will not be altered by accidental contact. This invention utilizes the extension and retraction characteristics of the spring to change the position of the upper housing, thereby achieving the connection and disconnection of the inlet and outlet terminals, and locking the upper housing to ensure the circuit's continuity and disconnection.

[0015] A connecting circuit is provided between the upper and lower housings. When the circuit needs to be connected, the conductive end of the conductor extending from the upper housing is inserted into the second pipe of the lower housing. The two ends of the conductor are connected to the energizing component, thus keeping the circuit in a conductive state. When the circuit needs to be disconnected, the upper housing is grasped or pushed upwards to separate the conductive end from the energizing component, thus disconnecting the circuit. Then, the upper housing is rotated in a circumferential direction to misalign the conductive end with the second pipe. After the conductive end aligns with the cavity or reserved slot, the grip is released, and the upper housing returns to its original position under the action of the spring, maintaining a close fit with the lower housing. However, the connecting circuit between the upper and lower housings is in an open state.

[0016] Compared with the prior art, the beneficial effects of this utility model are: stable conduction and circuit breaking performance, and no accidental contact will occur. Attached Figure Description

[0030] A connection module includes an insulating upper housing 1 and an insulating lower housing 2. The upper housing 1 is disposed above the lower housing 2. A movable rod 3 is disposed on the bottom surface of the upper housing 1 facing downwards. Two strip-shaped conductors 4 are disposed in the inner cavity of the upper housing 1, and both ends of any one of the conductors 4 are bent downwards to form conductive ends 5. The inner cavity of the lower housing 2 is provided with a first conduit 6 and four second conduits 7, all of which extend downwards to the lower side of the lower housing 2. The first conduit 6 is disposed in the middle of the inner cavity of the lower housing 2, and the four second conduits 7 are respectively disposed corresponding to the conductive ends 5. A cavity is formed between the first pipe 6 and the second pipe 7. The lower end of the movable rod 3 passes downward through the first pipe 6. The movable rod 3 and the first pipe 6 form a sliding pair along their length. A limiting ring 8 is fixedly sleeved on the lower end of the movable rod 3. A spring 9 is installed inside the first pipe 6 and is sleeved on the outer periphery of the movable rod 3. A retaining ring is fixedly installed on the upper part of the first pipe 6. The spring 9 is located between the retaining ring and the limiting ring 8. The spring 9 biases the upper housing 1 downward. Each of the second pipes 7 is connected to a power-conducting component. The four conductive ends 5 extend into the four second pipes 7 and are each connected to one of the aforementioned power-conducting components.

[0031] Furthermore, the lower outer periphery of any second pipe 7 is provided with external threads; the energizing assembly includes a sleeve 13, a limiting nut 14, a washer 15, and a screw 16. The sleeve 13 is tubular, and the upper end of the sleeve 13 is provided with several clamps 17 along the circumferential direction. The inner wall of the sleeve 13 is provided with internal threads, and the middle part of the sleeve 13 protrudes outward along the circumferential direction to form a convex ring. The sleeve 13 extends into the second pipe 7. The lower end of the limiting nut 14 is provided with a limiting ring. The limiting nut 14 is threadedly connected to the lower part of the second pipe 7. The limiting ring is located on the lower side of the convex ring. The screw 16 is threadedly connected to the internal threads of the sleeve 13. A washer 15 is provided between the screw 16 and the sleeve 13. The conductive end 5 extends into the sleeve 13.

[0032] Furthermore, an insulating baffle 10 is provided on the lower side of the lower housing 2, and the first pipe 6 and four second pipes 7 all pass downward through the insulating baffle 10.

[0033] Furthermore, the four conductive terminals 5 are arranged in a rectangular shape.

[0034] Furthermore, the side of the upper housing 1 protrudes outward to form a grip handle 11.

[0035] Furthermore, a dust cover 12 is provided on the top of the upper housing 1.

[0036] Furthermore, the lower end of the movable rod 3 is connected to the limiting ring 8 by a snap-fit ​​structure.

[0037] Furthermore, the lower housing 2 has a test hole 18 and a reserved groove 19 on its side wall, and the test hole 18 is connected to the second pipe 7.

[0038] Work process:

[0039] The device is mounted on the mounting plate 30, with the lower housing 2 connected to the mounting plate 30. Each energized component connected to the same conductor 4 serves as an input or output terminal, connected to the crimped wire (after placing the ring terminal at one end of the wire onto the screw 16 and tightening the screw 16 towards the insert 13, a circuit is formed between the wire, ring terminal, insert 13, conductive end 5, and conductor 4). The upper housing 1 is inserted into the lower housing 2 (the conductive ends 5 at both ends of the conductor 4 are inserted into the insert 13). The lower housing 2 can be considered a base, and the upper housing 1 can be considered an insulated handle. At this time, the circuit remains open. Due to the downward biasing force of the spring 9 on the upper housing 1, the upper housing 1 will not arbitrarily detach from the lower housing 2, thus preventing a circuit break.

[0040] like Figure 7As shown, spring 9 provides a constricting force that biases the upper housing 1 towards the lower housing 2, ensuring that the upper housing 1 covers the lower housing 2 in the normal state. Lifting the upper housing 1 upwards separates the conductive end 5 from the socket 13, breaking the circuit. Then, rotating the upper housing 1 circumferentially by a certain angle, moving the conductive end 5 away from the socket 13, and inserting the upper housing 1 downwards into the lower housing 2 (at this time, the conductive end 5 is inserted into the space between the first pipe 6 and the second pipe 7 in the lower housing 2, or into the reserved slot 19 on the side of the lower housing 2). The circuit remains open. Due to the downward biasing force of spring 9 on the upper housing 1, the upper housing 1 will not arbitrarily detach from the lower housing 2, preventing circuit exposure and potential accidents.

[0041] like Figure 9 As shown, the gripper 17 is arranged in a flower-shaped elastic opening structure along the circumferential direction, and the conductive end 5 is inserted into it, thus realizing the effect of conducting the circuit and clamping.

[0042] like Figure 10 As shown, test hole 18 is used to test whether the circuit is connected, which facilitates on-site maintenance and testing.

[0043] The lower end of the movable rod 3 is provided with an annular groove. The limiting ring 8 is engaged with the groove and the limiting ring 8 limits the lower end of the movable rod 3 to prevent the spring 9 from coming out of the lower end of the first pipe 6.

[0044] A grip handle 11 is provided on the side of the upper housing 1, which makes it easy to use the upper housing 1 as an insulated handle.
