Description
Technical field
The utility model relates to a kind of connector more particularly to a kind of wire casing water-proof connectors.
Background technique
It is all to be laid using floor socket outlet slot/box, and due to Metro AFC cloth in the AFC wiring system of subway
Wire casing is all placed in underground, flooded condition occurs so be easy to causeing in wiring system, this allows for cable long period of soaking and exists
In underground water, although the waterproof performance of present cable all increases, inevitable some cables are during the installation process
There is the case where broken skin, thus cause to leak electricity, and long-term immersion also decreases to the service life of cable, so need
AFC wiring groove is improved, make it have certain waterproof performance.
General wiring groove is rhs-structure, itself is waterproof, and needs using waterproof measure to be connecing for wiring groove
At seam, the most common way is exactly to weld, although can achieve waterproof performance, welding after wiring groove to the later period maintenance or
Replacement causes trouble, and welding significantly increases construction period.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of wire casing water-proof connector, not only may be used
To realize the water-proof sealing of wire casing seam crossing, it can also realize and be conveniently detached.
To achieve the above object, the utility model proposes following technical solutions: a kind of wire casing water-proof connector is mounted on two
It is covered with rubber pad on the medial surface of the seam crossing of a wire casing, upper clamp plate and lower clamp plate including pairing, upper clamp plate and lower clamp plate,
Wherein:
Upper clamp plate both ends downward bending forms angle and is greater than 90 ° of upper bound edge, surface have two longitudinal cuts by its
Three sub- bound edges are divided into, are vertically equipped with clamping plate on the outer wall on intermediate attached bag side, and offer mounting hole；
The upward bending in lower clamp plate both ends forms the lower bound edge that angle is greater than 90 °, surface have two longitudinal cuts by its
Three sub- bound edges are divided into, are vertically equipped with clamping plate on the outer wall on intermediate attached bag side, and offer mounting hole；
Upper clamp plate and lower clamp plate pairing are mounted on seam crossing, pass through mounting hole by bolt attaching nut and realize upper lower clamp plate
Mutually tightening.
Preferably, a plurality of reinforcing rib being parallel to each other of protrusion on the medial surface of the upper clamp plate and lower clamp plate, and rubber
Pad outer surface is correspondingly arranged on a plurality of groove, its groove and reinforcing rib cooperate when rubber pad is installed, and prevents rubber pad when tightening from moving
Position.
Preferably, the rubber pad is U-shaped, and its two sides bending length is greater than the length of bound edge.
Preferably, the reinforcing rib is four, intermediate two diameters are less than two of outside.
Compared with prior art, the revealed a kind of wire casing water-proof connector of the utility model, has the following beneficial effects:
The upper lower clamp plate of U-shaped structure can reduce difficulty of processing, and upper lower clamp plate is directly slice structure, whole after installation
Body height is smaller, the wire location more demanding suitable for size, in order to promote its whole intensity, adds reinforcement on its surface
Muscle quantity, and the rubber pad surface of inside is arranged to the groove matched with reinforcing rib, so that rubber pad when in use will not be wrong
Position, and strengthen pressing force；
For the bound edge of upper lower clamp plate two sides setting, and the angle of bound edge is greater than 90 degree, and opens up on bound edge vertical
To notch, so during installation, although when bolt is tightened being longitudinal force, due to bound edge be it is inclined, with screwing force
Increase, bound edge can form the side extruding force to rubber pad to contract, realize the compression cladding of side, ensure that
Waterproof performance.

Fig. 2 is the explosive view of the utility model；
Fig. 3 is the sectional side view of the utility model；
Fig. 4 is another sectional side view of the utility model.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete
Description.
As shown in Fig. 1 ~ 4, a kind of revealed wire casing water-proof connector of the utility model is mounted on connecing for two wire casings 11
At seam, upper clamp plate 1 and lower clamp plate 2 including pairing are covered with rubber pad 3 on the medial surface of upper clamp plate and lower clamp plate, the rubber
It pads U-shaped, is sponge rubber pad, there is certain thickness, and it is wavy on inner wall, it can increase after cladding and rub with wire casing
It wipes power and prevents from shifting, waterproof not only may be implemented in sponge rubber pad, and certain elasticity can increase the compression that connection fastening is
Power, it is ensured that sponge rubber pad is fitted closely with wire casing surface, so that it is guaranteed that waterproof performance.
For the structure of upper lower clamp plate, upper clamp plate both ends downward bending forms the upper bound edge 4 that angle is greater than 90 °, this
A bound edge realizes the side cladding of abutment joint, and two longitudinal cuts 5 are arranged on bound edge surface and are divided into three sub- bound edges,
It is vertically equipped with clamping plate 6 on the outer wall on intermediate attached bag side, and offers mounting hole 7, the structure of lower clamp plate is consistent with upper clamp plate,
The upward bending in both ends forms the lower bound edge 8 that angle is greater than 90 °, and there are two longitudinal cuts to be divided into three attached bags on surface
Side is vertically equipped with clamping plate on the outer wall on intermediate attached bag side, and offers mounting hole.
During installation, upper clamp plate and lower clamp plate are respectively placed in the upper and lower of seam, two mounting holes is passed through by bolt and are matched
It closes nut to be tightened, first apply upper lower clamp plate in rundown process is longitudinal extruding force, longitudinal to squeeze sponge rubber
Rubber mat makes it be bonded the upper and lower surface of wire casing, and mutual extrusion forms closed seam at the ends A of U-shaped rubber pad, due to only
There are upper and lower extruding force can not the sponge rubber pad to side wall form lateral plus-pressure, so bound edge is arranged to tilt,
After bolt is tightened to a certain extent, inclined bound edge inwardly bounces back, and the transverse shear stress power to sponge rubber pad is formed, in order to mention
Extruding force is risen, bound edge is separated, only intermediate region (seam crossing) is inwardly squeezed, is not only reduced outer when squeezing
It is exerting a force, is also promoting the obturation effect of seam crossing, realize that the surrounding of abutment joint is totally-enclosed, it is ensured that waterproof performance.
The upper clamp plate and lower clamp plate use slice structure, the thickness value after installation can be effectively reduced, and in order to be promoted
The reinforcing rib 9 of a plurality of protrusion is arranged in its intensity on the inner wall of upper lower clamp plate, preferably, using four reinforcing ribs, and it is intermediate
Two diameters are less than two of outside, its groove when rubber pad outer surface is correspondingly arranged on a plurality of groove 10, and rubber pad is installed
Cooperate with reinforcing rib, prevents rubber pad when tightening from shifting.
The technology contents and technical characteristic of the utility model have revealed that as above, however those skilled in the art still may be used
Can teaching based on the utility model and announcement and make various replacements and modification without departing substantially from the spirit of the present invention, therefore, this
Utility model protection range should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model
And modification, and covered by present patent application claim.
