Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a plugging and unplugging structure of a voltage meter pen. Background Art

[0002] With the continuous development of technology, the use of electricity in life has gradually increased. The use of more electrical equipment has increased the load of power facilities, and it is inevitable that some circuits will have problems. Usually, professional electricians are required for maintenance and detection. When maintenance personnel perform circuit inspection and repair, professional detection equipment and tools are needed. Usually, power equipment has a built-in voltage display, but it is inevitable that it will be damaged. Therefore, only the voltage detection part of the universal transformer is needed to detect and repair the circuit.

[0003] In some special cases, the automatic voltage display part of the electrical equipment is damaged, which usually indicates that the internal electrical components are abnormal and need to be detected with a multimeter. Due to abnormal voltage fluctuations, it is necessary to continuously detect the circuit electrical appliances for a period of time. General multimeter test leads cannot be kept for a long time for detection, which will cause overheating damage to the wire harness of the test leads and pose unnecessary potential safety hazards.

A on-off component is slidably installed inside the connection component, and an external connection component is installed at the lower end of the on-off component. The on-off component is always pushed against the contact component by magnetic force. When the on-off component overheats, the magnetic force will decrease, realizing the separation and disconnection of the on-off component and the contact component, and realizing the protection of the wire.

[0006] In at least some embodiments, a reinforcing block is installed at the connection position of the connection block of the connection component and the wire. A connection cylinder is provided at the head position of the connection block. The connection cylinder is perpendicular to the connection block. A connection frame is hingedly installed near the connection cylinder of the connection block. A positioning block is provided on the connection frame, and a notch is provided at the end of the connection frame.

[0007] In at least some embodiments, the shielding cylinder of the shielding assembly is sleeved and installed at the end of the connecting cylinder. A shielding block is hingedly installed on the shielding cylinder. The shielding block is set in the structure of a sector plate and is arranged in a circumferential array.

[0008] In at least some embodiments, the insulating cylinder of the contact assembly is arranged inside the connecting cylinder near the connecting block. The part of the insulating cylinder inside the connecting cylinder is connected and installed with an external contact post. An internal contact wheel is installed at the position of the connecting block of the insulating cylinder. A ring groove structure is arranged on the outer wall of the internal contact wheel. Both the external contact post and the internal contact wheel are made of metal structures, and the insulating cylinder adopts an insulating structure.

[0009] In at least some embodiments, the fuse block of the protection assembly is inserted and installed inside the contact assembly. An external connection block is arranged at the outer end position of the fuse block. An external connection plate is clamped and installed at the outer end position of the fuse block at the connection assembly. The inner end of the external connection plate is in clamped contact with the external connection block.

[0010] In at least some embodiments, the connecting block of the on-off assembly is slidably installed inside the connection assembly. The end of the connecting block corresponds to the ring groove of the internal contact wheel. An external control plate is connected and installed at the outer end position of the connecting block. A protrusion is arranged at the outer end position of the external control plate. The connecting block adopts a magnetic structure.

[0011] In at least some embodiments, the external connection post of the external connection assembly is arranged at the position of the reinforcement block at the tail of the connection assembly. The external connection post is connected to a wire. The external connection post is placed at the central axis position of the on-off assembly. A tension spring is installed at the outer end of the external connection post, and the tension spring is connected to the on-off assembly.

[0012] The present utility model provides a plugging and unplugging structure for a voltmeter test pen, which has the following beneficial effects:

[0013] In the present utility model, first, the connecting frame hingedly installed on the connection assembly enables the connecting frame to facilitate the disassembly and assembly of the entire connection assembly. The shielding assembly added to the end of the connecting cylinder of the connection assembly realizes the function of dust blocking during the plugging and unplugging of the connection assembly. The contact assembly is installed inside the connecting cylinder of the connection assembly. The insulating cylinder of the contact assembly is set as an insulating partition part. Only after installing the fuse block of the protection assembly can the inside and outside of the external contact post be connected. The fuse block can achieve overload protection. The on-off assembly sliding inside the connection assembly is set with a permanent magnetic structure, which will make the on-off assembly adsorbed at the internal contact wheel to realize the connection and connection of the on-off assembly and the contact assembly. The on-off assembly is connected to a wire through the external connection assembly. Only after the on-off assembly is overloaded and heated, the on-off assembly loses magnetism, realizing the separation of the on-off assembly from the internal contact wheel, thereby forming a safety disconnection function for the wire.

[0014] In addition, the reinforcing block at the wire connected by the connecting block can assist in increasing the stability between the connecting block and the wire. The connecting cylinder is set perpendicular to the connecting block to achieve the convenient installation of the overall connecting component. In order to facilitate the disassembly and assembly of the connecting component, the connecting frame is hingedly installed at the position where the connecting block is close to the connecting cylinder, so that the connecting frame can swing and unfold directly during use, increasing the hand-held contact surface of the connecting component and facilitating the removal of the connecting component. The positioning block set on the connecting frame assists in fixing the angle of the connecting frame, and the notch at the end of the connecting frame facilitates the manual fluctuation of the connecting frame.

[0015] In addition, in order to prevent sundries from entering the connecting cylinder, a shielding cylinder is directly installed at the end of the connecting cylinder, and shielding blocks with circumferential true cold are installed on the shielding cylinder. Each group of shielding blocks is set as a sector and arranged in close contact with each other to achieve the auxiliary blocking of the end of the connecting cylinder by the shielding blocks, while not affecting the plug-in installation of the connecting cylinder in the connecting hole.

[0016] In addition, the insulating cylinder at the connecting component is made of insulating material, while the outer contact posts and inner contact wheels at both ends of the insulating cylinder are made of metallic conductive material. Therefore, after the connecting component is installed in the connecting hole, the protection component needs to be installed at the contact component to achieve the connection of the outer contact posts and inner contact wheels by the protection component, and the connection between the contact component and the connecting hole is realized. Removing the protection component will make the contact component no longer in the connected state. The insurance block of the protection component is set as a consumable item. After the insurance block is installed in the contact component, both ends of the insurance block connect the contact component. The external board is snap-connected to the outer end position of the connecting component, and the inner end of the external board is snap-connected to the external block, so that the external board can conveniently take and place the insurance block through the external block.

[0017] In addition, the communicating block slidably installed in the connecting component directly abuts against the annular groove of the inner contact wheel, making the on-off component in contact and communication with the contact component. The communicating block is set as a magnetic structure, enabling the communicating block to adsorb on the inner contact wheel by itself. After the communicating block overheats due to overload, the magnetism of the communicating block will disappear, causing the communicating block to disengage from the inner contact wheel. When it is necessary to make the communicating block contact the inner contact wheel, the external control board at the outer end of the communicating block is directly fluctuated, enabling the on-off component to be controlled in position from the outside. The external connecting column is connected to the wire, and the external connecting column is directly set on the central axis of the on-off component with the connecting component, connecting the on-off component to the external component, and realizing the connection of the on-off component to the wire through the external component. The pull spring at the outer end of the external connecting column is connected to the on-off component, so that when the on-off component loses magnetism, the on-off component slides through the action of the pull spring.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0038] Embodiment 1: Please refer to Figures 1 to 6 :

[0040] In the embodiments of the present disclosure, as Figure 2 shown, a reinforcement block 202 is additionally installed at the connection position between the connection block 201 of the connection component 2 and the wire 8. A connection cylinder 204 is provided at the head position of the connection block 201, and the connection cylinder 204 is perpendicular to the connection block 201. The reinforcement block 202 at the position where the connection block 201 is connected to the wire 8 can assist in increasing the stability between the connection block 201 and the wire 8. The connection cylinder 204 set perpendicular to the connection block 201 realizes the convenient installation of the overall connection component 2. A connection frame 203 is hinged and installed at the position where the connection block 201 is close to the connection cylinder 204. A positioning block is provided on the connection frame 203, and a notch is provided at the end of the connection frame 203. In order to enable the convenient disassembly and assembly of the connection component 2, the connection frame 203 is directly hinged and installed at the position where the connection block 201 is close to the connection cylinder 204, so that the connection frame 203 can swing and unfold directly during use, increasing the hand-held contact surface of the connection component 2 and facilitating the removal of the connection component 2. The positioning block provided on the connection frame 203 assists in fixing the angle of the connection frame 203, and the notch at the end of the connection frame 203 facilitates the manual fluctuation of the connection frame 203.

[0041] In the embodiments of the present disclosure, as Figure 3As shown, the shielding cylinder 301 of the shielding component 3 is sleeved and installed at the end of the connecting cylinder 204. A shielding block 302 is hingedly installed on the shielding cylinder 301. The shielding block 302 is set as a sector plate structure and is arranged in a circumferential array. In order to prevent sundries from entering the connecting cylinder 204, the shielding cylinder 301 is directly installed at the end of the connecting cylinder 204, and a circumferentially arranged shielding block 302 is installed on the shielding cylinder 301. Each group of shielding blocks 302 is set as a sector and is arranged in close contact with each other, so that the shielding block 302 forms an auxiliary block for the end of the connecting cylinder 204, and at the same time, it does not affect the insertion and installation of the connecting cylinder 204 in the connecting hole 9.

[0042] In the embodiment of the present disclosure, as Figure 4 shown, the insulating cylinder 402 of the contact component 4 is arranged inside the connecting cylinder 204 near the connecting block 201. The outer contact posts 401 are connected and installed at the part of the insulating cylinder 402 in the connecting cylinder 204. An inner contact wheel 403 is installed at the position of the connecting block 201 of the insulating cylinder 402. The outer wall of the inner contact wheel 403 is provided with an annular groove structure. Both the outer contact posts 401 and the inner contact wheel 403 are made of metal. The insulating cylinder 402 is made of an insulating structure. First, the insulating cylinder 402 at the connecting component 2 is made of an insulating material, and the outer contact posts 401 and the inner contact wheel 403 at both ends of the insulating cylinder 402 are made of metal conductive materials. Therefore, after the connecting component 2 is installed in the connecting hole 9, the protection component 5 needs to be installed at the contact component 4 to enable the protection component 5 to connect the outer contact posts 401 and the inner contact wheel 403, so as to realize the connection between the contact component 4 and the connecting hole 9. Removing the protection component 5 will make the contact component 4 no longer in the connected state.

[0043] In the embodiment of the present disclosure, as Figure 5 Figure 6 shown, the fuse block 502 of the protection component 5 is inserted and installed inside the contact component 4. An external connection block 503 is arranged at the outer end of the fuse block 502. An external connection plate 501 is clamped and installed at the outer end position of the fuse block 502 at the connecting component 2. The inner end of the external connection plate 501 is in clamping contact with the external connection block 503. The fuse block 502 of the protection component 5 is set as a consumable item. After the fuse block 502 is installed in the contact component 4, both ends of the fuse block 502 connect the contact component 4. The external connection plate 501 is clamped at the outer end position of the connecting component 2, and the inner end of the external connection plate 501 is clamped and installed with the external connection block 503, so that the external connection plate 501 realizes the convenient taking and placing of the fuse block 502 through the external connection block 503.

[0044] Embodiment 2, on the basis of Embodiment 1, as Figure 5As shown, the connecting block 601 of the on-off component 6 is slidably installed inside the connecting component 2. The end of the connecting block 601 corresponds to the annular groove of the inner contact wheel 403. An external control board 602 is connected and installed at the outer end position of the connecting block 601. A protrusion is provided at the outer end position of the external control board 602. The connecting block 601 adopts a magnetic structure. The connecting block 601 slidably installed inside the connecting component 2 will directly abut against the annular groove of the inner contact wheel 403, enabling the on-off component 6 to be in contact and connection with the contact component 4. And since the connecting block 601 is set as a magnetic structure, the connecting block 601 can be self-adsorbed on the inner contact wheel 403. After the connecting block 601 overheats due to overload, the magnetism of the connecting block 601 will disappear, causing the connecting block 601 to disengage from the inner contact wheel 403. When it is necessary to make the connecting block 601 contact the inner contact wheel 403, the external control board 602 at the outer end of the connecting block 601 is directly fluctuated, enabling the position of the on-off component 6 to be controlled from the outside.

[0045] In the embodiment of the present disclosure, as Figure 5 shown, the external connection column 701 of the external connection component 7 is arranged at the position of the reinforcement block 202 at the tail of the connecting component 2. The external connection column 701 is connected to the wire 8. The external connection column 701 is placed at the central axis position of the on-off component 6. A tension spring 702 is installed at the outer end of the external connection column 701. The tension spring 702 is connected to the on-off component 6. The external connection column 701 is connected to the wire 8. And the external connection column 701 is directly arranged on the central axis of the connecting component 2 and the on-off component 6, enabling the on-off component 6 to be connected to the external connection component 7, realizing the function of connecting the on-off component 6 to the wire 8 through the external connection component 7. And the tension spring 702 at the outer end of the external connection column 701 is connected to the on-off component 6, so that when the on-off component 6 loses magnetism, the on-off component 6 slides through the tension spring 702.

[0046] The working principle of this embodiment: Before use, first observe whether the position of the external control board 602 is at the front end. At the same time, manually touch the external control board 602 to slide the on-off component 6 to identify whether the on-off component 6 can slide, and test whether the pulling force of the tension spring 702 on the on-off component 6 and the magnetism of the on-off component 6 itself are good. At this time, manually remove the external board 501 from the connecting component 2 and detect the on-off situation of the fuse block 502 of the protection component 5. After confirming that the fuse block 502 is in good condition, install the protection component 5 in place;

[0047] During use, directly insert the connecting cylinder 204 of the connecting component 2 into the connection hole 9 of the detection table 1, and then the detection pen of the wire 8 can be used;

[0048] When removing after use, swing the connecting frame 203 of the connecting component 2 outward, and directly hold the connecting frame 203 to conveniently pull out the connecting component 2 from the connection hole 9, and then collect the connecting component 2, the wire 8, etc.;

[0049] When an overload phenomenon occurs, the fuse block 502 in the contact component 4 will melt, and the fuse block 502 needs to be removed and replaced through the external board 501. In another case, the connecting block 601 will overheat, causing the connecting block 601 to demagnetize, and the tension spring 702 will pull down the connecting block 601, causing the connecting block 601 to disengage from the inner contact wheel 403, thereby achieving the disconnection effect. When using it again, the connecting block 601 needs to be reset through the external control board 602 for reuse after the connecting block 601 cools down.

[0053] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered by the protection scope of the present disclosure.
