The arc formed by the offset is a front view projection combination of the arc profile at the bottom end of the first groove 501a-1 and the arc profile formed at the barb of the first barb 501b, and the central angle of the arc is larger than 270 ° in the invention, so as to limit the grip 600.

In the first accommodating space C, a first baffle 501C-1 is arranged at a position away from the second side surface 501C by a certain distance, the first baffle 501C-1 is parallel to the surface of the second side surface 501C, and a first protrusion 501C-11 is arranged on the first baffle 501C-1. It should be noted that, in the present embodiment, the distance between the first baffle 501c-1 and the second side 501c is set to make the first baffle 501c-1 have a certain elastic potential energy space. Because the lower end of the first baffle 501c-1 is fixed and the upper end is suspended, and the first baffle 501c-1 is flaky and not blocky, the distance between the first baffle 501c-1 and the second side 501c is set, so that the first baffle 501c-1 has an elastic deformation space to a certain extent.

Further, the first accommodating space C further includes a third side 501d, and the third side 501d is a bottom surface of the first accommodating space C. The third side 501d is provided with a second groove 501d-1 and a second protrusion 501 d-2. When the connecting block 601 rotates upwards by 90 degrees around the outward protruding rotating shaft 601a from the horizontal position, the second protrusion 501d-2 is buckled with the first through hole 601 b. It should be noted that, in this embodiment, the second groove 501d-1 is a "U" -shaped through slot, and the second groove 501d-1 is provided to enable a baffle to be formed on the third side 501d, and the baffle can be elastically deformed. Similar to the first baffle 501c-1, one end of the baffle on the third side 501d is fixed, the other end is suspended due to the second groove 501d-1, and the baffle is sheet-shaped and not block-shaped, so that the baffle has elastic potential energy and deformation space to a certain extent.

The grip 600 includes a connection block 601 and a jaw 602, and the jaw 602 is disposed in the first receiving space C through the connection block 601. The connecting block 601 is hollow inside, and the claw 602 can be inserted into the hollow part of the connecting block 601. The connecting block 601 includes a male shaft 601a, a first through hole 601b, a second through hole 601c, a third protrusion 601d and a fourth through hole 601 e. The protruding rotation shaft 601a is symmetrically disposed on two side surfaces of the connection block 601, and is not disposed on a surface having the first through hole 601b and the second through hole 601 c. The convex rotating shaft 601a is clamped at a bayonet with a central angle larger than 270 degrees formed by mutually staggering the hook of the first barb 501b and the bottom end of the first groove 501a-1, the first through hole 601b and the second through hole 601c are positioned at opposite surfaces, and the first through hole 601b is matched with the first protrusion 501c-11 and used for limiting the connecting block 601.

From the above, the claw 602 is disposed in the first accommodating space C through the connecting block 601, and an L-shaped groove 602a is disposed at a port where the claw 602 and the connecting block 601 are connected to each other. The third protrusion 601d extends inward from the port of the second through hole 601c by a certain length (not greater than the width of the upper opening of the L-shaped groove 602 a), and the third protrusion 601d is matched with the L-shaped groove 602a to limit the vertical position relationship of the pawl 602. The claw 602 is further provided with a third through hole 602b, and the third through hole 602b is matched with the fourth protrusion 501c-12, so that when the connecting block 601 rotates upwards by 90 degrees around the outward rotating shaft 601a from a horizontal position, the fourth protrusion 501c-12 can just penetrate through the fourth through hole 601e to be embedded into the third through hole 602b and be buckled with the third through hole, and the connection limits and fixes the matching of the third protrusion 601d and the L-shaped groove 602 a. In the present invention, when the jaw 602 is inserted into the connection block 601, the fourth through hole 601e and the third through hole 602b communicate with each other.

In this embodiment, the outward protruding rotating shaft 601a is pressed downward along the direction from the front surface a to the back surface B, and the first barbs 501B can generate elastic deformation, so that the outward protruding rotating shaft 601a can pass through the barbs and be placed at the hook of the first barbs 501B and the bottom end of the first groove 501a-1 to form a bayonet with a central angle greater than 270 degrees. Due to the obstruction of the barbs, the outward protruding rotating shaft 601a cannot be separated from the bayonet generated by dislocation under the condition of no external force action, so that the outward protruding rotating shaft 601a is limited. The jaws 602 are connected to the connecting block 601 so that the outwardly protruding rotation shaft 601a can perform a rotational movement while being restricted in a moving direction. In view of this, the connection block 601 is caught by the first through hole 601b engaged with the first protrusions 501c-11, so that the grip 600 is in a horizontal state.

In summary, the two position states (horizontal state and vertical state) of the claw 602 are realized as follows: according to the above, after the outward protruding rotating shaft 601a is embedded into the bayonet formed by the first barb 501b and the first groove 501a-1, the claw 602 is rotated (to drive the connecting block 601 to rotate synchronously) to a vertical position, at this time, the first through hole 601b at the inner end of the connecting block 601 is fastened with the second protrusion 501d-2 to form a fixed state, and meanwhile, the fourth protrusion 501c-12 can also pass through the fourth through hole 601e to be embedded into the third through hole 602b to be fastened with the third through hole, so as to form a fixed lock for the third protrusion 601d to be matched in the L-shaped groove 602 a. In this state, the protective shell B-1 and the protective shell B-2 on the upper side of the connector 500 are retained by the claws 602 around them, and are held together. In addition, in the invention, the outer end of the claw 602 is also provided with an inward claw head 602d, and the claw head 602d can clamp the upper side surface of the outer protective shell B-2, so as to realize the sealing and fixing of the circuit board protective shell B-1 and the outer protective shell B-2.

When the protective shell B-1 of the circuit board and the protective shell B-2 of the outer layer need to be detached and separated, and devices on the circuit board B need to be replaced, the clamping claws 602 are rotated outwards to be in a horizontal state, and at the moment, the first through holes 601B are matched with the first protrusions 501c-11 to be clamped and fixed. Since the fourth protrusions 501c-12 are disengaged from the fourth through-holes 601e and the third through-holes 602b, the jaws 602 can be detached from the connection block 601.

Further, in the above process, the first through hole 601b is separated from the second protrusion 501d-2 or the first protrusion 501c-11 by the telescopic rod 602 c. Specifically, the jaw 602 is hollow inside, a telescopic rod 602c is arranged in the hollow structure, the telescopic rod 602c penetrates through the jaw 602, the outer end of the telescopic rod extends out of the hollow structure, and a section of end head for pressing is reserved outside. The telescopic rod 602c includes a front limiting pad 602c-1 and a rear limiting pad 602c-2, and an elastic member 602c-3 (the elastic member 602c-3 may be a spring) is disposed between the front limiting pad 602c-1 and the rear limiting pad 602c-2 and fixed to two ends of the elastic member 602 c-3. Wherein, the outer ring of the front limit gasket 602c-1 is engaged with the annular groove of the inner end of the jaw 602, which is fixed on the telescopic rod 602c, and the rear limit gasket 602c-2 is not fixed with the telescopic rod 602c (but fixed with the inner sidewall of the inner channel of the inner end of the jaw 602), and the rear limit gasket 602c-2 can slide along the axial direction of the rod body of the telescopic rod 602 c.

In use, assuming a horizontal position in the initial state, the claw 602 and the connection block 601 are locked in the horizontal position because the first through hole 601b is engaged with and caught by the first protrusions 501c-11 in the horizontal position. The end of the telescopic rod 602c protruding outside is pressed, at this time, because the outer ring of the front limiting gasket 602c-1 is matched with the annular groove of the inner end of the claw 602, the whole telescopic rod 602c can move inwards until the telescopic rod 602c abuts against the first protrusion 501c-11, so that the telescopic rod is elastically deformed inwards, the first protrusion 501c-11 of the first baffle plate 501c-1 is separated from the first through hole 601b, and the whole connecting block 601 can be unlocked and rotated. Since the rear spacer 602c-2 is fixed to the inner sidewall of the inner end of the claw 602, and the restoring force of the elastic member 602c-3 is added, the telescopic rod 602c automatically resets after the pressed telescopic rod 602c is released. Similarly, the process of separating the first through hole 601b from the second protrusion 501d-2 by using the telescopic rod 602c in the vertical state is also the same as the above process, and is not described herein again.

The combination of the connector 500 and the grip 600 of the present invention can be easily disassembled and assembled, and the jaws 602 have two positions, one being a horizontal position and the other being a vertical position. When the circuit board protective shell B-1 and the outer protective shell B-2 need to be tightly held and connected, the clamping jaws 602 can be combined and locked when being rotated to be in a vertical state; when the device of the circuit board B needs to be overhauled or replaced, the clamping jaw 602 can be rotated to be in a horizontal state, the constraint of the clamping jaw 602 on the outer-layer protective shell B-2 is removed, and the clamping jaw can be directly detached, so that the operation is convenient.
