Description

Technical Field

[0001] This utility model relates to the field of terminal connector center pin technology, and in particular to a quick-replaceable terminal connector center pin. Background Technology

[0002] Terminal connector center pins are metal contacts inside the connector used to transmit electrical and power signals. These pins are usually located in the center of the connector and are used to connect and transmit current or signals. In order to enable maintenance personnel to replace damaged center pins in a short time and reduce maintenance costs, a quick-replacement terminal connector center pin is used.

[0003] To address this, patent CN207572572U discloses a novel quick-replaceable connector terminal, comprising a connecting sleeve, an installation groove on one outer wall of the connecting sleeve, and a pull-out plate inserted into the inner wall of the installation groove. A first fixing block is fixedly connected to the position where the pull-out plate contacts the connecting sleeve. Rolling wheels are welded to the outer walls on both sides of the bottom of the pull-out plate, and a guide groove is welded to the inner wall of the bottom of the installation groove, forming a rolling connection between the rolling wheels and the guide groove. A first connecting terminal is welded to the inner wall of the installation groove, and elastic grooves are formed on both sides of the top outer wall of the first connecting terminal. A polymer plate is welded to one outer wall of the first connecting terminal, and the polymer plate is connected to the pull-out plate by bolts. This utility model facilitates the disassembly, assembly, and replacement of the connecting terminal by the operator. It has a simple structure, reasonable design, low manufacturing cost, reliable operation, convenient disassembly, and stable snap-fit.

[0004] While the aforementioned novel quick-replacement connector terminals facilitate disassembly, assembly, and replacement by the operator, their lack of protection during use makes it difficult to protect the center pin from damage when not in use, resulting in low safety during operation. Utility Model Content

[0005] The purpose of this invention is to provide a quick-replaceable terminal connector center pin to solve the problem that existing quick-replaceable terminal connector center pins are inconvenient to protect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick-replaceable terminal connector center pin, including a connector body and a mounting groove;

[0007] The connector body has a mounting groove on its top, a mounting base is provided inside the mounting groove, a center pin body is evenly provided on the top of the mounting base, and a protective structure is provided on the outer side of the center pin body. The protective structure includes a protective shell fitted on the top of the center pin body, a sealing ring is fixed at the bottom of the protective shell, and an anti-slip sleeve is fixed on the outer side of the top of the protective shell.

[0008] The interior of the mounting base at the bottom of the central needle body is equipped with a disassembly structure.

[0009] The mounting base has handles fixed on both sides of its top, and the connector body has fixing structures on both sides of its bottom.

[0010] When using this device, the protective structure facilitates the protection of the center pin body, thereby improving the safety of the terminal connector center pin during use; the fixing structure facilitates easy assembly and disassembly, thereby improving the applicability of the terminal connector center pin during use; and the disassembly structure facilitates quick replacement of the center pin body, thereby improving the convenience of using the terminal connector center pin.

[0011] Preferably, the bottom end of the protective shell contacts the top end of the mounting base, and a rubber block is fixed to the top of the protective shell. The protective shell contacts the top end of the center needle body through the rubber block. The sealing ring increases the friction between the protective shell and the connecting plate, thus fixing the protective shell to the outside of the center needle body and increasing the seal. The anti-slip sleeve increases the friction between the fingers and the protective shell, allowing the protective shell to be separated from and fixed to the center needle body. The protective shell and the rubber block protect the center needle body from damage when not in use.

[0012] Preferably, the fixing structure includes a movable groove, a movable rod, a return spring, a limiting block, a connecting frame, and a pull ring. The movable groove is formed on both sides of the bottom of the connector body. A limiting block is provided at one end of each movable groove. A movable rod is fixed to one side of each limiting block. One end of each movable rod extends to the outside of the connector body and is fixed with a pull ring. A return spring is sleeved on the outside of each movable rod inside the movable groove. A connecting frame is provided inside the mounting groove on one side of each limiting block.

[0013] Preferably, the movable rod and the limiting block form a telescopic structure via a return spring, and the limiting block and the connecting frame form a locking structure. The handle moves the mounting base into the mounting groove. Under the pressure of the connecting frame, the limiting block moves into the movable groove. When the bottom end of the connecting frame abuts against the bottom of the mounting groove, the return spring pushes the limiting block into the connecting frame, thus fixing the mounting base and the connector body together.

[0014] Preferably, the top end of the connecting frame is fixedly connected to the bottom end of the mounting base, and the bottom end of the connecting frame abuts against the bottom of the mounting groove. By pulling the movable rod with the pull ring, the movable rod causes the limiting block to separate from the connecting frame, thus separating the mounting base from the connector body, thereby enabling the disassembly and replacement of multiple sets of center pin bodies.

[0015] Preferably, the disassembly structure includes a snap-fit ​​groove, a snap-fit ​​block, a pre-drilled groove, and a connecting plate. The snap-fit ​​groove is located inside the mounting base at the bottom of the center pin body. Each snap-fit ​​groove contains a snap-fit ​​block, and each snap-fit ​​block contains a pre-drilled groove. The top of each snap-fit ​​block extends to the outside of the mounting base and is fixed with a connecting plate. When the snap-fit ​​block moves into the snap-fit ​​groove, the center pin body is fixed to the mounting base via the connecting plate.

[0016] Preferably, the snap-fit ​​block and the mounting base form an engaging structure through a snap-fit ​​groove. The top end of the connecting plate is fixedly connected to the bottom end of the center pin body, and the outer side of the connecting plate contacts the inner side of the sealing ring. Pulling the center pin body causes it to move the snap-fit ​​block to the outside of the snap-fit ​​groove via the connecting plate. At this point, the center pin body separates from the mounting base, allowing maintenance personnel to replace the center pin body quickly.

[0017] The present invention provides a quick-replaceable terminal connector center pin, the advantages of which are:

[0018] By incorporating a protective structure, the friction between the protective shell and the connecting plate is increased under the action of the sealing ring, thereby fixing the protective shell to the outside of the center pin body and increasing the sealing performance. Under the action of the anti-slip sleeve, the friction between the fingers and the protective shell is increased, thereby separating and fixing the protective shell and the center pin body. With the action of the protective shell and the rubber block, the center pin body can be protected from damage when not in use. This device facilitates the protection of the center pin body and improves the safety of the terminal connector center pin during use.

[0019] With a fixed structure, the mounting base is moved into the mounting groove by a handle. Under the squeezing action of the connecting frame, the limiting block moves into the movable groove. When the bottom of the connecting frame abuts against the bottom of the mounting groove, the limiting block is pushed into the connecting frame by the elastic force of the return spring. At this time, the mounting base and the connector body are fixed together. By pulling the movable rod with the pull ring, the movable rod drives the limiting block to separate from the connecting frame. At this time, the mounting base and the connector body are separated, so that multiple sets of center pin bodies can be disassembled and replaced. This realizes the function of easy disassembly and assembly of the device, thereby improving the applicability of the center pin of the terminal connector in use.

[0020] With a disassembly structure, when the snap-fit ​​block is moved into the snap-fit ​​slot, the center pin body is fixed to the mounting base via the connecting plate. Pulling the center pin body causes the snap-fit ​​block to move to the outside of the snap-fit ​​slot via the connecting plate, at which point the center pin body separates from the mounting base. This allows maintenance personnel to replace the center pin body quickly, thus improving the convenience of using the terminal connector's center pin. Attached Figure Description

[0028] Please see Figures 1-5This utility model provides a quick-replaceable terminal connector center pin, including a connector body 1 and a mounting groove 2. The top of the connector body 1 is provided with the mounting groove 2, and the inside of the mounting groove 2 is provided with a mounting seat 3. The top of the mounting seat 3 is evenly provided with center pin bodies 8, and the outer side of the center pin bodies 8 is provided with a protective structure 4. The protective structure 4 includes a protective shell 401 sleeved on the top of the center pin bodies 8, a sealing ring 402 fixed at the bottom of the protective shell 401, and an anti-slip sleeve 403 fixed on the outer side of the top of the protective shell 401. The bottom end of the protective shell 401 contacts the top end of the mounting seat 3, and a rubber block is fixed on the top of the protective shell 401. The protective shell 401 contacts the top end of the center pin body 8 through the rubber block.

[0029] Reference Figure 2 and Figure 4 As shown, the anti-slip sleeve 403 increases the friction between the finger and the protective shell 401. The anti-slip sleeve 403 moves the protective shell 401, causing it to fit over the outside of the center needle body 8. The inner side of the sealing ring 402 contacts the outer side of the connecting plate 704. The sealing ring 402 increases the friction between the protective shell 401 and the connecting plate 704, thus fixing the protective shell 401 to the outside of the center needle body 8 and increasing the sealing performance. This allows the protective shell 401 to be separated from and fixed to the center needle body 8. With the help of the protective shell 401 and the rubber block, the center needle body 8 can be protected from damage when not in use.

[0030] The interior of the mounting base 3 at the bottom of the center needle body 8 is provided with a disassembly structure 7. The disassembly structure 7 includes a snap-fit ​​groove 701, a snap-fit ​​block 702, a reserved groove 703, and a connecting plate 704. The snap-fit ​​groove 701 is opened inside the mounting base 3 at the bottom of the center needle body 8. The snap-fit ​​groove 701 is provided with a snap-fit ​​block 702 inside. The snap-fit ​​block 702 is provided with a reserved groove 703 inside. The top of the snap-fit ​​block 702 extends to the outside of the mounting base 3 and is fixed with the connecting plate 704. The snap-fit ​​block 702 and the mounting base 3 form a snap-fit ​​structure through the snap-fit ​​groove 701. The top of the connecting plate 704 is fixedly connected to the bottom of the center needle body 8. The outer side of the connecting plate 704 is in contact with the inner side of the sealing ring 402.

[0031] Reference Figure 2 and Figure 3As shown, the center pin body 8 is moved to the connecting plate 704, so that the bottom end of the snap-fit ​​block 702 abuts against the top end of the snap-fit ​​groove 701. Pressing the center pin body 8, under the action of the reserved groove 703, the center pin body 8 drives the snap-fit ​​block 702 to move into the inside of the snap-fit ​​groove 701 through the connecting plate 704. At this time, the center pin body 8 and the mounting base 3 are fixed to each other. Pulling the center pin body 8, the center pin body 8 drives the snap-fit ​​block 702 to move to the outside of the snap-fit ​​groove 701 through the connecting plate 704. At this time, the center pin body 8 and the mounting base 3 are separated from each other, so that maintenance personnel can replace the center pin body 8 in a short time.

A return spring 603 is sleeved on the outside of the movable rod 602 inside the movable groove 601. A connecting frame 605 is provided inside the mounting groove 2 on one side of the limiting block 604. The movable rod 602 and the limiting block 604 form a telescopic structure through the return spring 603. The limiting block 604 and the connecting frame 605 form a locking structure. The top of the connecting frame 605 is fixedly connected to the bottom of the mounting base 3. The bottom of the connecting frame 605 abuts against the bottom of the mounting groove 2.

[0033] Reference Figure 2 and Figure 5 As shown, the handle 5 moves the mounting base 3 into the mounting groove 2. Under the squeezing action of the connecting frame 605, the limiting block 604 moves into the movable groove 601. When the bottom end of the connecting frame 605 abuts against the bottom of the mounting groove 2, the spring force of the return spring 603 pushes the limiting block 604 into the connecting frame 605. At this time, the mounting base 3 and the connector body 1 are fixed together. The pull ring 606 pulls the movable rod 602, causing the movable rod 602 to separate the limiting block 604 from the connecting frame 605. At this time, the mounting base 3 and the connector body 1 are separated, so that multiple sets of center pin bodies 8 can be disassembled and replaced.
