Abstract
The utility model discloses a sealed detachable cable joint which is a sealed connecting member used for connecting and conveying electricity and solves the problem of the cable connection in the complex environment. The wire connection position of the joint is insulated and sealed inside a fixing sleeve. For various cables, the corresponding sealing ring and sealing plug can be adopted according to the diameter of the cable which needs to be connected. Compression nuts are rotated to generate pressure, and namely, the cables are sealed and connected in dismountability. The sealing ring of the joint has ring-shaped partial pressure peaks, and the sealing plug has a sealant store room. Thus, sealing is safe, and tensile strength is high. The utility model is convenient to mount and dismount, and is suitable for the seal and connection of cables such as the electrical appliance and cables, cable distribution units, and the middle joints of cables under the environments of wet areas, water, underground areas, combustible and explosive areas, etc. in each field of the national economy.
Description
A kind of tie cable is carried electric sealed attachment parts.It is characterized in that selecting corresponding sealing plug and sealing ring for all kinds of cables for use according to cable size, with simple tools such as spanner, screwdrivers, rotation, clamp nut produce pressure and can carry out the dismoutability sealed attachment to cable.Be applicable in aerial, underground, the water, inflammable and explosive, the cable intermediate joint under the environment such as humidity, the cable branch device is in the connecting of cable and other electrical equipment.
In the various power circuits, usually need with cable and cable, cable and various electrical equipment positive connection, to reach the purpose of in various complex environments, electric power safety being delivered to reliably electrical appliance.
Present existing technology is that cable connection adopts lead sleeve formula, epoxy resin casting, plastic, rubber adhesive tape, multiple joint such as heat-shrink tube in moist, underground, water, in the adverse circumstances such as inflammable and explosive.These joints connect installs complexity, is easier to produce problems such as poor sealing electric leakage or insufficient strength, and can not dismantles after once using and reuse.
The utility model provides a kind of sealing detachable electrical cable joint, can address the above problem preferably.In various electrical equipment, cable branch device, cable intermediate joint,, the cable joint of output, input is designed and produced into sealing detachable electrical cable joint by required transmission of electricity character (interchange, direct current, single-phase, three-phase, voltage, electric current etc.).During tie cable, select corresponding sealing plug and sealing ring for use according to the diameter of need tie cable.The centre bore that single core that need are connected or multicore cable pass clamp nut and sealing ring and sealing plug, interior accordingly after terminals are fixed (alternate manners such as also available welding, hinge joint) with screwdriver and joint.Screw clamp nut with spanner, compress pair of seal rings.Because the annular branch voltage crest of the fluid sealant on the branch indent both sides that can force the rubber seal plug end face part to the sealing surface compression arranged on the opposite planar of sealing ring, the pressure of clamp nut forces the inside external seal face compression of the branch indent side seal glue envelope at the sealing plug two ends between the sealing ring tight by annular branch voltage crest, produces very big frictional force and makes the Seal of Cables position that very high tensile strength be arranged.Simultaneously because the sealing plug middle part has under pressure dry seal glue not to press to two or more storeroom of sealing surface, the pressure at two ends reaches positiver sealing with extrude the out space that is full of seal section cable outer surface and the space of sealing plug external seal face of the non-drying sealant in the storeroom in the middle part of the sealing plug.Thereby with better simply instrument, easily cable and required coupling components have been linked up, and sealing property is reliable, and linking intensity is big, and is safe in utilization.Need not cut off cable also can be for convenience detach and reuse.
Accompanying drawing has been described an example of the present utility model.
Fig. 1 is a kind of sealed attachment figure of two cores sealing detachable electrical cable joint.Select and pass in and out the sealing detachable electrical cable joint that the electrical property requirement is fit to for use.With the inner of the column type fixed cover (13) of joint with epoxy resin or other encapsulant (7) fixed insulation be sealed in electrical appliance, send electrical equipment, the wiring position of cable branch device, cable intermediate joint.The diameter of tie cable (1) as required, selected sealing plug (4) that adapts and sealing ring (3), (6).Cable (1) is passed from the centre bore of clamp nut (2), upper sealing ring (3) (the branch voltage crest is inside), sealing plug (4) lower sealing ring (6) (the branch voltage crest is outside) successively, operate housing pin (8), (12) with screwdriver and the cable termination lead is fastened on required union end (9), (11) goes up forms such as (also connect with inside conductor) available welding, (10) are the insulating barriers that prevents short circuit between heart yearn.Then lower sealing ring (6), sealing plug (4), upper sealing ring (3) para-electric cable (1) are successively carefully pushed fixed cover (13) bottom, cable (1) is drawn along also fixed suitable sealing position, rotatably compress nut (2) mobile contact seal ring (3) back in fixed cover with spanner again and produce inside pushing force, make upper and lower sealing ring (3), (6) apply relative pressure sealing plug (4).The branch voltage crest of sealing ring (3), (6) forces sealing plug (4) two ends to divide cable (1) outer surface and fixed cover (13) the inner surface compression envelope of indent side seal glue to contact with it tight under pressure.Clamp nut (2) revolves tightly more, and applied pressure is big more, seal tight more, thereby produce great frictional force, make cable (1) seal member that very high tensile strength be arranged.Rotatably compress the pressure that nut (2) produces simultaneously and also non-drying sealant (5) extruding in the storeroom of sealing plug (4) middle part is come out, be full of with sealing plug (4) stage casing and connect the space that space and sealing plug (4) outer surface of cable (1) outer surface on boundary contact with fixed cover.Because the dividing potential drop peak pressure of sealing ring (3), (6) is compeled the fluid sealant at sealing plug two ends, makes non-drying sealant can not flow out seal section, thereby realize the performance of positiver sealing.
During dismounting, only need withdraw from clamp nut (2), taking-up sealing ring (3), (6), sealing plug (4) can be pulled down cable easily.Refill non-drying sealant in the storeroom of sealing plug (4), joint can be reused again.
Fig. 2 is the cutaway view of sealing plug.Sealing plug can be designed to two or many storerooms that can store non-drying sealant, and (18) are the sealing plugs that respectively there are an annular storeroom (14), (17) in the place of inner outer surface.(15) be the sealing plug that respectively there are three annular storerooms in the place of inner outer surface.(16) be that annular on the sealing plug end face is divided indent.Each sealing plug all has the corresponding minute indent of branch voltage crest with corresponding sealing ring, so that sealing time-division voltage crest is cut the sealed at both ends glue of sealing plug to the sealing surface compression seal.
The utility model has solved humidity, in underground, the water, in the environment such as inflammable and explosive, and the reliable cable connection problem of safe ready.And applied widely, long service life, simple in structure, easy to make, cost is lower, reusable, be generalized to industry, agricultural, fishery, capital construction, mine and national economy other field, can obtain the good social benefit.
