In one embodiment, the elastic limiting rack 252 may be a deformable structure such as an elastic metal rack or an elastic plastic rack, so as to achieve elastic deformation and elastic clamping of the elastic waterproof gasket 24.

And, the material of the elastic limit rack 252 is the same as that of the limit main body 251, and the elastic limit rack 252 and the limit main body 251 are integrally formed, so that the structural integrity of the elastic limit rack 252 and the limit main body 251 is improved, the service life of the limit piece 25 is further prolonged, and the production cost is saved.

In addition, since the plurality of elastic limit racks 252 are distributed along the inner peripheral wall of the limit piece 25 in the present embodiment, the elastic waterproof gasket 24 is elastically clamped by the plurality of elastic limit racks 252, which means that the elastic waterproof gasket 24 elastically abuts against the plurality of elastic limit racks 252 around the position where the limit piece 25 is mounted, not with all the elastic limit racks 252. When the stopper 25 is moved relative to the elastic waterproof gasket 24, the elastic waterproof gasket 24 may be in contact with all of the elastic stopper racks 252 one by one or with most of the elastic stopper racks 252 one by one.

More, the plurality of elastic limiting racks 252 distributed in the length direction of the limiting member 25 are uniformly distributed on the inner wall of the limiting member 25, or are equally spaced on the inner wall of the limiting member 25, so that the elastic clamping force on the elastic waterproof gasket 24 is more uniform, so that the clamping is more stable, and the installation of the limiting member 25 is more stable.

Referring to fig. 6 and 7, further, the cross section of the limiting member 25 is in a waist-shaped hole shape, and the chute 22 is disposed on the long side wall of the limiting member 25.

Thus, after the board end connector 10 is assembled and locked on the limiting member 25, the limiting member 25 can limit the position of the sliding block 12, so as to limit the rotation of the board end connector 10, so that the board end connector 10 can only slide left and right on the limiting member 25, and the assembly stability of the board end connector 10 and the data acquisition rod 20 is improved.

Referring to fig. 6 and 7, further, a limiting step 221 is disposed at the tail of the chute 22, and the limiting step 221 extends toward the top of the limiting member 25.

Thus, after the board end connector 10 and the data acquisition rod 20 are installed in place as shown in fig. 3, that is, after the slide block 12 is embedded into the limiting step 221 along the sliding groove 22, the slide block 12 can be pressed into the limiting step 221 based on the upward acting force of the elastic waterproof gasket 24 on the board end connector 10, that is, the acting force towards the top of the limiting piece 25, so that the assembly locking of the board end connector 10 and the data acquisition rod 20 is more stable, and the problem that the slide block 12 slides out of the sliding groove 22 to affect the waterproof performance can be prevented.
