The access of cable 200 is in the accommodating cavity 11a.
For the sealing effect for further strengthening the cable 200, in the present embodiment, the elastic component 14 is by elastic material
It is made, and the elastic component 14 passes through the clamping element 13 and stretches in the non-tapered end of the wiring through-hole 121, it is described
14 partial receipt of elastic component is simultaneously fixed in the first hollow portion 13a, and it is hollow to be provided with second on the elastic component 14
Portion 14a, to access the cable 200.In the present embodiment, the elastic component 14 is tubular structure, and the elastic component
Material be silicon rubber, to guarantee that it has good elastic force and deformation force.
The elastic component 14 includes the first end 14b being oppositely arranged and second end 14c, and the part first end 14b accommodates
In in the first hollow portion 13a, length be greater than the connecting pin 13c of the clamping element 13 length and the wiring through-hole
The sum of the cone height of 121 tapered ends, so that the first end 14b of the elastic component 14 is at least after the cable 200 access
Have and partially protrude into the non-tapered end of the wiring through-hole 121, is generated when between the clamp nut 12 and the shell 11
When pressing force acts on, due to the clamping action of the clamping element 13, elastic deformation can occur for the first end 14b, to make
It obtains the first end 14b to be rigidly secured in the first hollow portion 13a, so that access is in second hollow portion
The cable 200 of 14a can also be clamped by the first end 14b, further clamp the cable 200 to reach
Purpose.Further, since the elastic component 14 has certain elastic force, and since it uses silicon rubber to be made, so that
It has certain sealing effect, under the action of the clamping element 13 and the elastic component 14, so that the cable
Introducing device 10 also has stronger sealing effect, to improve the safety in utilization of the cable introducing device 10 and mention
Its high applicability.
One block of abutting plate 141 is provided on the second end 14c, the abutting plate 141 is connected to the accommodating cavity 11a's
On bottom wall.In the present embodiment, the abutting plate 141 is the circular sheet being set on the second end 14c, and the abutting
The material of plate 141 is also silicon rubber.When the elastic component 14 to be connect with the clamping element 13, and pass through the clamp nut 12
And when 11 clamping action of shell, the abutting plate 141 with the bottom wall of the accommodating cavity 11a for abutting, to prevent
Under the clamping force effect of the clamping element 13, the elastic component 14 is entirely placed in the first hollow portion 13a, and leads to institute
The access for stating cable 200 is difficult.Simultaneously as the abutting plate 141 is connected on the bottom wall of the accommodating cavity 11a, thus
So that when clamping the cable 200, the abutting plate 141 can also be provided certain elastic force make the clamping element 13 into
One step clamps the first end 14b, and then further enhances the clamping effect of the cable 200.
When wiring, the cable 200 is sequentially passed through into the wiring through-hole 121, the first hollow portion 13a and institute
The second hollow portion 14a is stated, then the pinching end 13b is placed in the wiring through-hole 121, then by the first end 14b
Be placed in the first hollow portion 13a, the above-mentioned portions house that combination is completed in the accommodating cavity 11a of the shell 11,
And pass through the pressuring action of the clamp nut 12, so that the clamping element 13 and the elastic component 14 firmly clamp institute
