DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the application will be apparently and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0019] Please refer to Figures 1 to 9 The application provides a technical solution: a latch lock type connector, comprising a connector body 1, the top of the connector body 1 is provided with a groove 2, the groove 2 is provided with a clamping mechanism 3, the clamping mechanism 3 comprises a buckle 301, the buckle 301 is provided with a terminal channel 302, the two sides of the top of the buckle 301 are symmetrically fixed with buckles 303, and the buckles 303 are clamped and connected to the connector body 1.

[0020] In the embodiment, as shown in Figure 2 , Figure 3 , Figure 4 and Figure 7 , the buckles 303 are fixed with pulling pieces 304, and the outer sides of the pulling pieces 304 are connected with clamping blocks 306 through pulling ropes 305. When the buckle 301 is buckled to the connector body 1, the buckles 303 made of elastic material are automatically clamped to the connector body 1, so that the connector is conveniently and quickly installed. When the clamping blocks 306 are pulled upwards, the pulling pieces 304 are moved under the pulling action of the pulling ropes 305, so that the buckles 303 are pried and separated from the connector body 1, and the buckle 301 is conveniently and quickly dismounted.

[0021] In the embodiment, as shown in Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, two sides of the upper end surface of the buckle 301 are symmetrically provided with clamping grooves 307, and the clamping blocks 306 are clamped and connected in the clamping grooves 307. The clamping blocks 306 are polygonal structures, and the clamping grooves 307 play a clamping and limiting role on the clamping blocks 306.

[0022] In this embodiment, as shown in Figure 4 , Figure 6 and Figure 8 , a fan-shaped groove 308 is formed in the clamping block 306, and a rotating shaft 309 is rotatably connected in the fan-shaped groove 308. One side of the rotating shaft 309 is fixedly provided with a protruding block 310. When the rotating shaft 309 is rotated, the protruding block 310 rotates together with the rotating shaft 309.

[0023] In this embodiment, as shown in Figure 4 , Figure 6 and Figure 8 , the protruding block 310 is movably connected in the fan-shaped groove 308, and the protruding block 310 is connected with the clamping block 306 through a spring 311. The spring 311 plays a supporting role on the protruding block 310. When the rotating shaft 309 and the protruding block 310 are rotated as a whole, the spring 311 is compressed. After the rotating shaft 309 is released, the protruding block 310 will automatically pop open under the action of the spring 311, and the rotating shaft 309 will automatically rotate back.

[0024] In this embodiment, as shown in Figure 4 , Figure 6 and Figure 8 , the other side of the rotating shaft 309 is fixedly provided with a locking rod 312, and the locking rod 312 is movably connected to the outer end surface of the clamping block 306. The locking rod 312 plays a locking role on the clamping block 306. When the rotating shaft 309 is rotated, the locking rod 312 can rotate together with the rotating shaft 309.

[0025] In this embodiment, as shown in Figure 4 , Figure 6 and Figure 8 , an arc-shaped groove 313 is formed in the buckle 301, and the locking rod 312 penetrates through the outer end surface of the clamping block 306 and extends into the arc-shaped groove 313. The locking rod 312 is initially located in the arc-shaped groove 313, and the locking rod 312 cannot move upward, which can play a role in locking the clamping block 306.

[0026] In this embodiment, as shown in Figure 5 , Figure 6 and Figure 9 , a notch 314 is formed in the buckle 301, and the notch 314 is in communication with the end of the arc-shaped groove 313. After the rotating shaft 309 and the locking rod 312 are rotated as a whole and the locking rod 312 reaches the notch 314, the upper part of the locking rod 312 is not limited, and at this time the clamping block 306 can be pulled out of the clamping groove 307.

[0027] In this embodiment, as shown in 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.

[0028] The method of use and advantages of this invention: The working process of this pin-locking connector is as follows: 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.

[0029] In summary, this pin-locking connector achieves the goal of convenient installation and disassembly, meeting people's usage needs.
