Abstract
The invention discloses a three-layer sealed wiring structure comprising a lead. The three-layer sealed wiring structure is characterized in that the three-layer sealed wiring structure also comprises a sleeve sealing element with a step-shaped cross section, an O-shaped sealing ring and a sealing nut, wherein the sleeve sealing element is divided into an upper step and a lower step; the outer surface of the lower step of the sleeve sealing element is sheathed with an O-shaped seal ring; and the outer side of the O-shaped seal ring is provided with the sealing nut; a hollow square base is fixedly connected on the housing of a junction box; the rear wall of the square base is provided with a through hole; the outer side of the square base is provided with outer screw nuts; the inner side of the sealing nut is provided with inner screw nuts; the square base is sheathed on the outer side of the O-shaped sealing ring to cover the sleeve sealing element and the O-shaped seal ring; and the sealing nut is matched with the thread to tightly press the square base. The invention solves the problem that the contact position of the junction box and the lead has poor sealing effect, is easy to flood and has short circuit in the prior art. The invention provides a three-layer sealed wiring structure with simple structure, convenient use and better sealing effect.
Description
Technical field
The present invention relates to the hermetically-sealed construction of lead, particularly relate to a kind of three-layer sealed wiring structure.
Background technology
The quality of the life of Along with people's improves gradually, and the increasing terminal box that uses is (long such as circuit at the joint area of lead; Perhaps conduit is wanted corner, perhaps is connected with circuit elements device module) will adopt terminal box to use as transition; Lead is connected with terminal box, and the circuit in the terminal box is being coupled together, and plays guardwire and the effect that is connected lead; But present lead and the contacted position of terminal box; Because of there not being the better seal structure, use the wire external layer insulator to be worn unavoidably simultaneously for a long time, regular meeting's generation water or moisture penetrate into the inner situation of lead along conductive line surfaces like this; Influence insulation effect, even cause short trouble.
Summary of the invention
Bad in order to solve in prior art lead and the terminal box connection procedure sealing effectiveness, water inlet easily, the problem of the situation that is short-circuited.The invention provides a kind of simple in structurely, easy to use, have the three-layer sealed wiring structure of better sealing effectiveness.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of three-layer sealed wiring structure; Comprise that lead, cross section are sleeve seal, O RunddichtringO and the sealing nut of stepped ramp type; Said sleeve seal is divided into tops bar and gets out of a predicament or an embarrassing situation, and the outer surface of getting out of a predicament or an embarrassing situation in sleeve seal is arranged with the O RunddichtringO, is provided with sealing nut in the outside of O RunddichtringO; Said lead passes sealing nut and sleeve seal; It is characterized in that: on the shell of terminal box, be fixedly connected with the round seat of hollow, the rear wall of round seat is provided with through hole, and the lead that passes sealing nut and sleeve seal can pass round through hole and be connected with the terminal box internal circuit; Arranged outside at round seat has external screw thread; Inboard at sealing nut is provided with internal thread; Round cover for seat is located at the outside of O RunddichtringO; Sleeve seal and O RunddichtringO are wrapped, and sleeve seal top bar than get out of a predicament or an embarrassing situation more near the rear wall of round seat, said sealing nut compresses round seat through threaded engagement.
Aforesaid a kind of three-layer sealed wiring structure is characterized in that: the height that said sleeve seal is topped bar is higher than the height that sleeve seal is got out of a predicament or an embarrassing situation.
The invention has the beneficial effects as follows: the present invention is provided with three-layer sealed structure at lead and the contacted place of terminal box; Can prevent that the situation such as leak electricity short-circuit that cause because of the wire external layer insulation breakdown from taking place; While sealing nut and round seat threaded engagement; Utilize sealing nut that round seat, sleeve seal, O RunddichtringO are compressed, realized the sealing effectiveness of high-quality more.

Fig. 2 is the cutaway view of Fig. 1 along A-A.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further description
As illustrated in fig. 1 and 2; Three-layer sealed wiring structure; Comprise that the cross section is sleeve seal 1, O RunddichtringO 2, sealing nut 3 and the lead 9 of stepped ramp type, sleeve seal 1 be divided into top bar 4 with get out of a predicament or an embarrassing situation 5,4 the height of topping bar is higher than 5 the height of getting out of a predicament or an embarrassing situation; Be arranged with O RunddichtringO 2 at get out of a predicament or an embarrassing situation 5 outer surface of sleeve seal 1, be provided with sealing nut 3 in the outside of O RunddichtringO 2.Be fixedly connected with the round seat 6 of hollow on the shell of said terminal box, the rear wall 7 of round seat 6 is provided with through hole, and said lead 9 passes sealing nut 3, sleeve seal 1, round seat 6 successively, and is connected with the inner circuit of terminal box; Arranged outside at round seat 6 has external screw thread; Inboard at sealing nut 3 is provided with internal thread; The sidewall 8 of round seat 6 is set in the outside of O RunddichtringO 2; Sleeve seal 1 and O RunddichtringO 2 are wrapped, and sleeve seal 1 top bar 4 more near the rear wall 7 of round seat 6, said sealing nut 3 compresses round seat 6 through threaded engagement.Sleeve seal 1 is provided with tops bar 4, can play the effect of replacing to O RunddichtringO 2, and sealing nut 3 rotates in the process of screwing like this, and O RunddichtringO 2 can not come off from sleeve seal 1, has strengthened sealing effectiveness, has prolonged useful life.
Show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
