Description

Technical Field

[0001] This invention pertains to electrical components, and more specifically to the field of connectors, and more particularly to a pin-locking type connector. Background Technology

[0002] Connectors bridge gaps in circuits, bridging interruptions and connecting isolated circuits to allow current to flow and enable the circuit to perform its intended function. Connector forms and structures are incredibly diverse, varying depending on the application, frequency, power, and environment. More broadly, connectors connect more than just electrical current. In today's rapidly developing optoelectronic technology, optical fiber systems use light as the signal carrier, with glass and plastic replacing wires in conventional circuits. However, connectors are still used in optical signal paths, serving the same function as electrical connectors.

[0003] Existing connectors require the use of clips to secure the terminals inside the connector during use. The clips are only used to fasten the connector after the terminals are installed, which is inconvenient for installation. Furthermore, once the clips are installed, they are difficult to separate from the connector, making disassembly inconvenient. To address these issues, the existing equipment needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a pin-locking connector to solve the problems mentioned in the background art, which require the use of fasteners to snap and fix the terminals inside the connector during use. The fasteners are only used to fasten the terminals inside the connector after the terminals are installed, which is not convenient for installation. Moreover, once the fasteners are installed, they are difficult to separate from the connector, making disassembly inconvenient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pin-lock type connector, comprising a connector body, a groove on the top of the connector body, a snap-fit ​​mechanism disposed in the groove, the snap-fit ​​mechanism comprising a fastener, a terminal channel on the fastener, and two symmetrical buckles fixed on both sides of the top of the fastener, the buckles engaging and connecting to the connector body.

[0006] Preferably, a pull tab is fixed inside the buckle, and the outer side of the pull tab is connected to the buckle block by a pull rope.

[0007] Preferably, the upper surface of the fastener has symmetrical slots on both sides, and the locking block is engaged in the slots. The locking block has a polygonal structure.

[0008] Preferably, the card block has a fan-shaped groove, and a rotating shaft is rotatably connected in the fan-shaped groove, with a protrusion fixed on one side of the rotating shaft.

[0009] Preferably, the protrusion is movably connected within the fan-shaped groove, and the protrusion is connected to the locking block via a spring.

[0010] Preferably, a locking rod is fixed to the other side of the rotating shaft, and the locking rod is movably connected to the outer end face of the locking block.

[0011] Preferably, the fastener has an arc-shaped groove inside, and the locking rod passes through the outer end face of the locking block and extends into the arc-shaped groove.

[0012] Preferably, the fastener has a notch that communicates with the end of the arc-shaped groove.

[0013] Preferably, a rotating block is fixed to the top of the rotating shaft, and a pull ring is rotatably connected to the rotating block.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This pin-locking connector facilitates installation. The fastener can be pre-attached to the connector body, and then the terminals can be connected to the connector body and locked into the terminal channel, thus completing the terminal installation. There is no need to wait until the terminals are installed before attaching the fastener to the connector body.

[0016] 2. This pin-lock type connector facilitates easy assembly and disassembly. When the fastener is fastened to the connector body, the buckle automatically locks onto the connector body, providing a locking function. Before removing the fastener, first rotate the pull ring upright, then hold the pull ring and rotate the rotating block and locking rod to allow the locking rod to enter the notch. After that, pull the locking block upwards. The pulling plate moves under the pulling action of the pull rope and pries the buckle, making it easy to unlock the fastener. The fastener can then be easily removed. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 9 The present invention provides a technical solution: a pin-lock type connector, including a connector body 1, a groove 2 is provided on the top of the connector body 1, a snap-fit ​​mechanism 3 is provided in the groove 2, the snap-fit ​​mechanism 3 includes a fastener 301, a terminal channel 302 is provided on the fastener 301, and buckles 303 are symmetrically fixed on both sides of the top of the fastener 301, and the buckles 303 are snapped and connected to the connector body 1.

[0029] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a pull tab 304 is fixed inside the buckle 303, and the outer side of the pull tab 304 is connected to the locking block 306 via a pull rope 305. When the fastener 301 is fastened to the connector body 1, the elastic buckle 303 will automatically lock onto the connector body 1 for easy and quick installation. When the locking block 306 is pulled upward, the pull tab 304 will move under the pulling action of the pull rope 305, thereby prying the buckle 303 and making it leave the connector body 1, so as to facilitate quick removal of the fastener 301.

[0030] In this embodiment, as Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the upper surface of the fastener 301 has symmetrical slots 307 on both sides, and the locking block 306 is engaged and connected in the slot 307. The locking block 306 has a polygonal structure, and the slot 307 plays a role in locking and limiting the locking block 306.

[0031] In this embodiment, as Figure 4 , Figure 6 and Figure 8 As shown, a sector-shaped groove 308 is provided in the card block 306, and a rotating shaft 309 is rotatably connected in the sector-shaped groove 308. A protrusion 310 is fixed on one side of the rotating shaft 309. When the rotating shaft 309 is rotated, the protrusion 310 rotates together with the rotating shaft 309.

[0032] In this embodiment, as Figure 4 , Figure 6 and Figure 8 As shown, the protrusion 310 is movably connected in the sector groove 308, and the protrusion 310 is connected to the locking block 306 through the spring 311. The spring 311 provides support for the protrusion 310. When the rotating shaft 309 and the protrusion 310 are rotated as a whole, the spring 311 is compressed. After the rotating shaft 309 is released, the protrusion 310 will automatically spring open under the action of the spring 311, and the rotating shaft 309 will automatically rotate back.

[0033] In this embodiment, as Figure 4 , Figure 6 and Figure 8 As shown, a locking rod 312 is fixed on the other side of the rotating shaft 309, and the locking rod 312 is movably connected to the outer end face of the locking block 306. The locking rod 312 locks the locking block 306. When the rotating shaft 309 is rotated, the locking rod 312 can rotate together with the rotating shaft 309.

[0034] In this embodiment, as Figure 4 , Figure 6 and Figure 8 As shown, the buckle 301 has an arc-shaped groove 313, and the locking rod 312 passes through the outer end face of the locking block 306 and extends into the arc-shaped groove 313. The locking rod 312 is initially located in the arc-shaped groove 313 and cannot move upward, which can lock the locking block 306.

[0035] In this embodiment, as Figure 5 , Figure 6 and Figure 9 As shown, the fastener 301 has a notch 314, which is connected to the end of the arc groove 313. After the entire rotating shaft 309 and locking rod 312 are rotated and the locking rod 312 reaches the notch 314, the upper part of the locking rod 312 is unrestricted. At this time, the locking block 306 can be pulled out from the slot 307.

[0036] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a rotating block 315 is fixed to the top of the rotating shaft 309, and a pull ring 316 is rotatably connected to the rotating block 315. The pull ring 316 can be rotated to stand up before rotating the rotating block 315, and the pull ring 316 can be rotated to put down after rotating the rotating block 315. This can prevent accidental operation. When the rotating block 315 is rotated by holding the pull ring 316, the rotating shaft 309, the protrusion 310 and the locking rod 312 rotate as a whole, which makes it easy to unlock the card block 306.

[0037] The method of use and advantages of this invention: The working process of this pin-locking connector is as follows:

[0038] like Figures 1 to 9 As shown: First, pre-fasten the buckle 301 in the groove 2. The buckle 303 automatically snaps onto the connector body 1. Then, connect the terminal to the connector body 1 and snap it into the terminal channel 302 to complete the terminal installation. If it is necessary to remove the buckle 301, first rotate the pull ring 316 to stand it up. Then, hold the pull ring 316 and rotate the rotating block 315, the rotating shaft 309, the protrusion 310 and the locking rod 312. The locking rod 312 moves in the arc groove 313 and finally enters the notch 314. The upper part of the locking rod 312 is unrestricted. Then, manually pull the rotating block 315 upward. The locking block 306 moves upward accordingly. The pulling piece 304 moves under the pulling action of the pull rope 305, thereby prying off the buckle 303 and unlocking the buckle 301. Then the buckle 301 can be removed smoothly.

[0039] In summary, this pin-locking connector achieves the goal of convenient installation and disassembly, meeting people's usage needs.
