In order to solve the technical problem, the utility model discloses a technical scheme does:
a cable access protective joint comprises two base plates which are respectively arranged on two sides of an electric box board, wherein the two base plates are connected with the electric box board through a plurality of joints;
the connector comprises a screwed pipe, the lower end of the screwed pipe is connected with a nut arranged in the electric box, the upper end of the screwed pipe is connected with a locking sleeve arranged outside the electric box, a sealing gasket is arranged between the locking sleeve and the backing plate, and a pipe orifice at the upper end of the screwed pipe is in a horn shape with a wide outside and a narrow inside;
the locking sleeve comprises a circular truncated cone-shaped supporting block, a threaded hole is formed in the supporting block, a first insertion pipe is connected to the upper end of the threaded hole, the lower end of the first insertion pipe is horn-shaped, a plurality of openings are formed in the first insertion pipe, the upper end of the screw pipe is connected into the threaded hole of the supporting block, and the first insertion pipe is inserted into the opening at the upper end of the screw pipe.
The pipe orifice of the lower end of the screw pipe is in a horn shape with an outer width and an inner width, the lower end of the screw pipe is connected with a screw sleeve, a second insertion pipe is connected in the screw sleeve, the shape of the upper end of the second insertion pipe is in the horn shape, a plurality of openings are formed in the second insertion pipe, the lower end of the screw pipe is connected in the screw pipe, and the second insertion pipe is inserted in the pipe orifice of the lower end of the screw pipe.
A rubber pad is stuck on the inner wall of the first intubation tube.
The utility model has the advantages that: the utility model combines each joint with two gaskets, enlarges the contact surface with the wall of the electric box, and further, when the cable in a single joint is pulled, the tensile force born by the cable is born by the whole upper surface of the electric box, thereby effectively avoiding the deformation of the electric box; on the other hand, first intubate and second intubate can be with in the cable is fixed to the solenoid, avoid the cable to move from top to bottom, improve connecting cable's stability.
Drawings
The invention is further described below with reference to the accompanying drawings:
figure 1 is a schematic front view structure diagram of the utility model in use,
figure 2 is a schematic view of the structure of the utility model,
fig. 3 is a schematic cross-sectional view taken along line a-a in fig. 2.
In the figure: the electric box comprises an electric box 1, a backing plate 2, a threaded pipe 3, a nut 4, a locking sleeve 5, a threaded sleeve 6, a sealing gasket 7, a first insertion pipe 51, an opening 52, a rubber gasket 53 and a second insertion pipe 61.
Detailed Description
As shown in fig. 1 to 3, a cable access protective joint comprises two base plates 2 respectively arranged at two sides of an electrical box board, wherein the two base plates 2 are connected with the electrical box board through a plurality of joints;
the connector comprises a screwed pipe 3, the lower end of the screwed pipe 3 is connected with a nut 4 arranged in the electric box, the upper end of the screwed pipe 3 is connected with a locking sleeve 5 arranged outside the electric box, a sealing gasket 7 is arranged between the locking sleeve 5 and the backing plate 2, and a pipe orifice at the upper end of the screwed pipe 3 is in a horn shape with a wide outside and a narrow inside;
the locking sleeve 5 comprises a circular truncated cone-shaped supporting block, a threaded hole is formed in the supporting block, the upper end of the threaded hole is connected with a first insertion tube 51, the lower end of the first insertion tube 51 is horn-shaped, a plurality of openings 52 are formed in the first insertion tube 51, the upper end of the screw tube 3 is connected in the threaded hole of the supporting block, and the first insertion tube 51 is inserted into the opening at the upper end of the screw tube 3.
The mouth of pipe of 3 lower extremes of screwed pipe is the tubaeform of a narrow in outer width, is connected with a swivel nut 6 at 3 lower extremes of screwed pipe, has second intubate 61 in the swivel nut 6 connection, and second intubate 61 upper end shape is tubaeform, has seted up many openings 52 on second intubate 61, 3 lower extremes of screwed pipe are connected in screwed pipe 3, second intubate 61 inserts in the mouth of pipe of 3 lower extremes of screwed pipe.
A rubber pad 53 is adhered to the inner wall of the first cannula 51. The rubber pad 53 is used to seal the gap between the first cannula 51 and the cable from rainwater penetrating into the gap between the first cannula 51 and the cable.
The utility model discloses a use method does: after each cable is put in and out of each joint, the locking sleeve 5 is rotated to enable the first insertion pipe 51 to be inserted into the pipe orifice at the upper end of the spiral pipe 3, and the locking sleeve 5 is required to compress the sealing gasket 7 tightly, because the first insertion pipe 51 is in inclined surface fit with the pipe orifice at the upper end of the spiral pipe 3, when the locking sleeve 5 is rotated, the first insertion pipe 51 can fix the cable to prevent the cable from moving up and down, and because the sealing gasket 7 is arranged between the locking sleeve and the backing plate 2, the rainwater can be effectively prevented from falling into the electric box; on the other hand, one end of the cable in the electrical box can be fixed by the second insertion tube 61, so that the stability of the cable connection is improved.
