Description

Technical Field

[0001] This utility model relates to the field of instrument connection technology, specifically to a quick connection device for power debugging instruments. Background Technology

[0002] Traditional power debugging instruments primarily rely on two connection methods: threaded connection or pin crimping. Threaded connections require manual rotation of the thread 3 to 5 turns to complete the connection, which is particularly inconvenient in high-altitude work environments, especially when operating with one hand, significantly increasing the difficulty. On average, each connection takes at least 45 seconds, severely impacting work efficiency. Secondly, pin-type connections rely on spring pressure for contact. However, in environments with frequent vibrations, this method easily leads to contact resistance exceeding standard limits (greater than 5 milliohms), causing the contact point temperature to rise and posing a potential safety hazard. Furthermore, neither of these connection methods is equipped with a mechanical interlock design. Accidental contact can easily cause the test leads to detach, interrupting the debugging process and potentially triggering arcing, posing a serious threat to the safety of operators and equipment. Therefore, we propose a quick connection device for power debugging instruments. Utility Model Content

[0003] To address the technical problems mentioned in the background section, this utility model provides a quick connection device for power debugging instruments.

[0004] To solve the above problems, this utility model adopts the following technical solution:

[0005] A quick-connect device for power debugging instruments includes a connector socket and a plug body. The connector socket has a power connection hole at its upper center, and a plug holder is fixedly attached around the upper side of the power connection hole. The plug holder has symmetrical hook slots on both sides, each hook slot being an L-shaped through-hole structure. The vertical end of the hook slot penetrates the side wall of the plug holder. The horizontal section of the hook slot is positioned close to the bottom of the plug holder, and a positioning slot is located at the upper end of the horizontal section. The plug body is inserted into the plug holder, and hanging protrusions are fixedly connected to both sides of the bottom side wall of the plug body, with the hanging protrusions matching the size of the hook slots. A power connection pin is fixedly connected to the center of the bottom of the plug body, and the side wall of the power connection pin has multiple rings of power connection grooves. The inner wall of the power connection hole on the connector socket has multiple rings of pin power connection clips corresponding to the multiple rings of power connection grooves.

[0006] Furthermore, the outer wall of the power-connecting pin is provided with a power-connecting ring corresponding to the center of the power-connecting groove, and both sides of the power-connecting groove are inclined structures. The power-connecting clip of the pin is a plurality of elastic copper sheets that are deflected toward the center.

[0007] Furthermore, an annular slot is provided on the upper end of the connector corresponding to the outer ring of the inner wall of the plug socket, and an elastic support cylinder is movably inserted into the annular slot. A support compression spring is fixedly connected between the bottom of the elastic support cylinder and the bottom of the annular slot.

[0008] Furthermore, a spare connector ring is fixedly connected to the bottom outer ring of the plug body, and a spare connector pad is fixedly connected to the upper end of the elastic support cylinder.

[0009] Furthermore, a hook-connected electrical ring is fixedly connected to the middle of the outer wall of the mounting protrusion, and a hook-connected electrical contact is fixedly connected to the top of the positioning slot at the end of the hook slot, and the hook-connected electrical contact is in contact with the outer wall of the hook-connected electrical ring.

[0010] Furthermore, a rubber friction pad is fixedly connected to the upper inner wall of the plug socket.

[0011] The beneficial effects of this utility model are as follows:

[0012] The plug body of this utility model is secured to the hook slots on both sides of the plug socket by a mounting protrusion, with the end of the mounting protrusion engaging in a positioning slot. This ensures the plug body is stably secured within the plug socket, preventing wobbling and poor connection. The power pin is inserted into the power socket, and the engagement of the pin clip with the groove ensures stable connection between the plug body and the socket. The L-shaped through-hole design of the hook slots allows the mounting protrusion to slide horizontally along the hook slot into the positioning slot after being engaged, completing the installation of the plug body. Similarly, during disassembly, simply push the mounting protrusion to slide it out along the hook slot, allowing the plug body to be pulled out of the plug socket. This enables quick assembly and disassembly, is convenient, saves time and effort, and improves the efficiency of power commissioning.

[0013] This invention utilizes a contact ring to facilitate quick docking of the pin contact clip with the contact groove. Simultaneously, the two side walls of the contact groove are beveled, allowing the pin contact clip to deflect to both sides when compressed, thus facilitating the insertion of the contact pin. The pin contact clip consists of multiple elastic copper sheets deflected towards the center, allowing the clip to fit tightly against the contact groove through its own elasticity, thereby improving the stability of the connection.

[0014] This invention, through the provision of a spare contact ring on the plug and a spare contact pad on the socket, facilitates improved connection stability when there is poor connection between the contact pin and the contact clip. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] Please see Figure 1 - Figure 3 This utility model provides a quick connection device for power debugging instruments, including a connection socket 1 and a plug body 4. The upper center of the connection socket 1 has a power connection hole, and a plug holder 2 is fixedly fixed around the upper side of the power connection hole. The plug holder 2 has hook slots 3 symmetrically opened on both sides. The hook slots 3 are L-shaped through structures, and the vertical end of the hook slots 3 penetrates through the side wall of the plug holder 2. The horizontal section of the hook slots 3 is set close to the bottom of the plug holder 2, and a positioning slot is opened on the upper side of the end of the horizontal section of the hook slots 3. The plug body 4 is inserted into the plug holder 2, and the bottom sides of the side wall of the plug body 4 are fixedly connected to the hanging protrusions 5, and the size of the hanging protrusions 5 matches the hook slots 3. The bottom center of the plug body 4 is fixedly connected to a power connection pin 6, and the side wall of the power connection pin 6 is provided with multiple rings of power connection grooves. The inner wall of the power connection hole on the connection socket 1 is provided with multiple rings of pin power connection clips 7 corresponding to the multiple rings of power connection grooves.

[0021] The working principle and usage process of this utility model are as follows: During use, the plug body 4 is engaged with the hook grooves 3 on both sides of the plug socket 2 by the mounting protrusion 5, and the end of the mounting protrusion 5 is engaged with the positioning groove, so that the plug body 4 is stably engaged in the plug socket 2, avoiding the situation where the plug body 4 shakes and causes poor power connection. The power connection pin 6 is inserted into the power connection hole, and through the cooperation of the pin power connection clip 7 and the power connection groove, the plug body 4 is stably connected to the connection socket 1. Due to the L-shaped through structure of the hook groove 3, after the mounting protrusion 5 is engaged in the hook groove 3, it can be pushed to slide the mounting protrusion 5 along the horizontal section of the hook groove 3 into the positioning groove, thus completing the installation of the plug body 4. Similarly, when disassembling, simply push the mounting protrusion 5 to slide it out along the hook groove 3, and the plug body 4 can be pulled out from the plug socket 2, realizing quick disassembly and assembly, convenient operation, saving time and effort, and improving the efficiency of power debugging work.

[0022] In this embodiment, preferably, a contact ring is provided on the outer wall of the contact pin 6 corresponding to the center of the contact groove, and both sides of the contact groove are inclined structures. The contact pin clip 7 consists of multiple elastic copper sheets deflected towards the center. The contact ring facilitates quick docking between the contact pin clip 7 and the contact groove. At the same time, the inclined structure of both sides of the contact groove facilitates the deflection of the contact pin clip 7 to both sides when squeezed, thereby facilitating the insertion of the contact pin 6. The multiple elastic copper sheets deflected towards the center allow the contact pin clip 7 to fit tightly against the contact groove through its own elasticity, improving the stability of the connection.

[0023] In this embodiment, preferably, the upper end of the connecting socket 1 has an annular slot on the outer ring of the inner wall of the plug holder 2, and an elastic support cylinder 8 is movably inserted into the annular slot. A support compression spring 9 is fixedly connected between the bottom of the elastic support cylinder 8 and the bottom of the annular slot. With the elastic support cylinder 8 and the support compression spring 9, when the plug body 4 is inserted into the plug holder 2, the plug body 4 squeezes the elastic support cylinder 8, causing the elastic support cylinder 8 to move downward and squeeze the support compression spring 9. The reaction force of the support compression spring 9 causes the elastic support cylinder 8 to abut against the plug body 4, improving the stability of the plug body 4 and the connecting socket 1.

[0024] In this embodiment, preferably, a spare plug contact ring 12 is fixedly connected to the bottom outer ring of the plug body 4, and a spare socket contact pad 13 is fixedly connected to the upper end of the elastic support cylinder 8. The spare plug contact ring 12 and the spare socket contact pad 13 facilitate the improvement of the connection stability when the connection between the plug pin 6 and the plug pin contact clip 7 is poor.

[0025] In this embodiment, preferably, a hook-connecting ring 11 is fixedly connected to the middle of the outer wall of the mounting protrusion 5, and a hook-connecting contact 10 is fixedly connected to the top of the positioning slot at the end of the hook groove 3, and the hook-connecting contact 10 contacts the outer wall of the hook-connecting ring 11. The hook-connecting contact 10 and the hook-connecting ring 11 are provided to facilitate the stability of the connection when the mounting protrusion 5 is engaged in the hook groove 3, and to avoid poor contact.

[0026] In this embodiment, preferably, a rubber friction pad is fixedly connected to the upper side of the inner wall of the plug holder 2; the rubber friction pad increases the friction between the inner wall of the plug holder 2 and the outer wall of the plug body 4, prevents the plug body 4 from shaking, and improves the stability of the plug body 4 and the connection socket 1.
