DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described below in conjunction with specific embodiments. Among them, the attached drawings are only for illustrative purposes, showing only schematic diagrams rather than physical diagrams, and should not be construed as a limitation to this patent; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the attached drawings may be omitted.

[0018] The buzzer retraction module of the present utility model includes a fixed seat 1, a positioning block 2 and a buzzer assembly. The positioning block 2 is arranged on the top of the fixed seat 1 and can move upward relative to the fixed seat 1 and return to its original position. A cavity 4 is formed at the top of the positioning block 2. The cavity can have various shapes, which are not specifically limited, and its shape is adapted to the outer shape of the plug-in part for placing the plug-in part. A buckle assembly 3 is arranged at the top of the positioning block 2 adjacent to the cavity 4, and the buckle assembly is used to fix the plug-in part. The buzzer assembly includes a buzzer housing 5 arranged on the outer side wall of the positioning block 2. A battery box 6 for placing a battery is arranged inside the buzzer housing 5. A buzzer 7 and a microswitch 8 are respectively arranged inside the buzzer housing 5. The buzzer 7 is electrically connected to the microswitch 8 and the battery box 6 respectively, and the microswitch 8 is electrically connected to the battery box 6. A pressing plate 9 is arranged on one side of the fixed seat 1 adjacent to the buzzer housing 5. The pressing plate 9 extends into the buzzer housing 5 and is located above the microswitch 8, corresponding to the transmission element of the microswitch.

[0019] During use, place the plug-in part in the cavity, fix the plug-in part with the buckle assembly to make it immobile, then insert the wire with the terminals pressed into the specified through hole of the plug-in part. After completing the operations of inserting once and listening twice, pull the wire upward. Since the plug-in part itself is fixed on the positioning block and does not move, pulling it upward will drive the positioning block to move upward, and then drive the buzzer housing to move upward. The microswitch inside the buzzer housing touches the pressing plate to achieve closure. At this time, the buzzer is powered on to give an alarm, reminding that the terminal is inserted in place, and another wire with the terminals pressed can be inserted continuously. After completing the operations of inserting once and listening twice, still pull the wire upward according to the above steps. If it is inserted in place but not pulled back, the buzzer will not alarm; if the wire is not inserted in place, when pulling it upward, under the action of the weight of the positioning block, the microswitch has not touched the pressing plate, and the wire will come out of the through hole of the plug-in part.

[0020] A microswitch is a commonly used electronic switch device with two contact leads. There is a transmission element (such as a push pin, button, lever, roller, etc.) on the microswitch housing. When an external force acts on the transmission element, the on-off operation of the microswitch is realized. In this embodiment, a normally open microswitch is selected. When an external mechanical force acts on the microswitch through the transmission element, the circuit is connected.

[0021] Considering that when workers are using it, when the two buzzer retraction modules are relatively close, it may be difficult to distinguish which retraction module the sound comes from. To enhance the prompting effect, the buzzer assembly further includes an indicator light 17 arranged on the top of the buzzer housing. The indicator light 17 is electrically connected to the microswitch 8 and the battery box 6 respectively. When the microswitch inside the buzzer housing touches the pressure plate to achieve closure, the buzzer is powered on for warning, and at the same time the indicator light is lit to remind that the terminal is inserted in place.

[0022] In this embodiment, a battery box 6 for placing batteries is arranged inside the buzzer housing. On the outer side of the buzzer housing, a detachable side plate (not shown in the figure) is arranged at a position corresponding to the battery box to facilitate battery installation. On the side of the buzzer housing 5 away from the battery box, accommodation holes for installing the indicator light 17, the buzzer 7, and the microswitch 8 are respectively opened from top to bottom, and the accommodation holes can communicate with each other to facilitate wiring. A through hole for the indicator light to expose is opened at the top of the buzzer housing, and a sound hole is opened at a position on the outer side of the buzzer housing corresponding to the buzzer to facilitate the diffusion of sound.

[0023] In this embodiment, the positioning block is arranged on the top of the fixed seat in this way. A plurality of convex through holes 10 penetrating through the top and bottom are vertically opened on the fixed seat 1. At least two of the convex through holes are arranged diagonally. A blind hole 11 is opened at a position corresponding to the convex through hole 10 at the bottom of the positioning block. A retraction connecting rod 12 is arranged in the convex through hole 10. A circular limiting piece 13 is arranged at the lower end of the retraction connecting rod 12. The diameter of the circular limiting piece is larger than the small diameter section of the convex through hole and smaller than its large diameter section to ensure that the retraction connecting rod can move upward and does not fall out. The upper end of the retraction connecting rod 12 extends into the blind hole 11 at the bottom of the positioning block and is fixed by bolts. Under the action of the retraction connecting rod, the fixed seat can move upward to a certain distance, so that the buzzer housing fixed on one side of the fixed seat can drive the microswitch to move upward, and its transmission element touches the pressure plate to achieve the closure of the microswitch.

[0024] Further, a compression spring 14 is sleeved on the lower part of the retraction connecting rod 12 located in the center of the fixed seat 1. The compression spring 14 is located in the lower large diameter section of the convex through hole 10 and abuts against the inner top of the lower large diameter section of the convex through hole 10 and the circular limiting piece respectively. Under the action of the compression spring, the retraction connecting rod can drive the positioning block to return to the top of the fixed seat.

[0025] At the same time, to facilitate the installation of the fixed seat, a plurality of threaded blind holes 15 for fixing are opened at the bottom of the fixed seat. During use, bolts are passed through from the bottom to fix the fixed seat in a suitable position.

[0026] In this embodiment, the top of the positioning block away from the buzzer assembly is concave to form a clearance area 16 connected to the top of the cavity, and the buckle assembly 3 is arranged in the clearance area 16; the buckle assembly 3 includes a buckle seat 31 and a wrench 32, and the bottom of the buckle seat 31 is provided with a through slot that runs through its front side and an adjacent side, and the wrench 32 is rotatably arranged in the through slot through a fixed shaft 33, and a torsion spring is sleeved on the fixed shaft 33. Under the action of the torsion spring, the front end of the wrench 32 extends into the cavity to form a fixed end 321, and the rear end of the wrench 32 extends from the other side of the through slot to form a toggle end 322. Specifically, the wrench is provided with an open slot near the inner side of the through slot, and a torsion spring is sleeved on the fixed shaft located in the open slot.

[0027] Figures 1 - 3 The state of the buckle assembly shown is the natural state of the wrench under the action of the torsion spring, in which the connector is fixed. When placing the connector, push the wrench toggle end forward to rotate the wrench fixed end into the through slot. At this time, the cavity is unobstructed and the connector can be placed. Then release the wrench toggle end. Under the action of the torsion spring, the wrench automatically returns to its initial state, its fixed end extends, and the bottom of the fixed end presses the top edge of the connector to fix the connector.

[0028] The above description is only the preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications, combinations and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the scope of the claims of the utility model.
