Abstract

The utility model discloses a cable sealing device provided with a jacket, which can seal and protect an insulation layer of a cable joint, and comprises two annular pieces which are in half pairing. The edges at two ends of the annular piece extend outwards transversely to form transverse edges; the edge part at one side surface of the annular piece extends outwards transversely to form a transverse edge; the inner side of a circular hole formed by the paring of the two annular pieces can be sheathed and combined with the tubular jacket; a pairing hole is arranged at the transverse edge, and an installation hole is arranged at the transverse edge. The cable sealing device is capable of sealing and fixing a connection cable, and particularly has the advantage of being convenient for disassembling in cable change.

Description

A kind of cable sealing device that has sheath

Technical field

The utility model belongs to a kind of electric accessories, relates to a kind of import and export sealing of cable and the protection of stube cable external insulation, more specifically, is a kind of annex that can seal and can protect cable insulation.

Background technology

In the prior art; The joint system of cable adopts the line ear to be connected on the equipment, for anti-sealing or moisture intrusion along the cable surface slit, on the cable of equipment outside, is wrapped with rubber ring usually; By plug screw rubber ring is carried out the spinning sealing, and be fixed on the housing of equipment by plug screw.

Existing plug screw is knockdown, and its fit through two tubular spares is pressed on rubber ring in the taper hole, is adjacent to by the rubber ring of deformation and is passing on the cable of plug screw.The problem that this plug screw exists is: palpus elder generation plug screw and rubber ring on cable joint-box when one, using, again cable joint is connected on the equipment, and increased trouble in the operation; Two, when needs moved to other equipment with cable or change, because the existence of line ear, the diameter of cable joint made cable from the through hole of plug screw, to withdraw from greater than the internal diameter of plug screw, have to cut off cable, not only bothers but also waste.Three, the rubber ring of this plug screw configuration can only adapt to the cable with its size match, and therefore, it only is applicable to a kind of cable of specification.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art and a kind of cable sealing device that has sheath is provided, and this cable sealing device has convenience operation, and can be adapted to adopt banded rubber bodies to seal.

Its purpose is realized by following scheme:

A kind of cable sealing device that has sheath is characterized in, comprises the ring-shaped article of two semi-involutions; Ring-shaped article all forms the widthwise edge edge in the edge at two ends along laterally stretching out, the edge along continuous straight runs of ring-shaped article in the side formation horizontal edge that stretches out; But its inboard fit of circular hole that is encircled into the sheath of a tubulose by two ring-shaped articles; On the widthwise edge edge, have involutory hole, on horizontal edge, have installing hole.

Like this; The cable joint-box upper jacket that can connect; And be combined on the sheath by the involutory circle hole sleeve that it surrounds of two ring-shaped articles, can be by bolt through involutory hole with two ring-shaped article packings, circular hole is tightened up and through sheath be close to cable joint around on; Moreover, can through installing hole cable sealing device be fixed on the shell etc. of machinery equipment by bolt.

Thus obtained cable sealing device; Can play fixing effect to stube cable, avoid cable tension to concentrate acting on the tie point and be prone to make tie point that the problem of breaking off takes place, help alleviating the damage of external force pulling cable butting head; Play the effect of protection jointing; And through the effect of sheath, can let the application point of pulling force be dispersed on the whole sheath, can further play and avoid force localization easily device to be constituted bigger infringement.

In the such scheme, but fit between its inboard of circular hole that is encircled into and the sheath the rubber tube of reeling and forming by the rubber bodies of band shape by two ring-shaped articles.

Like this; By bolt through involutory hole during with two ring-shaped article packings; Can make circular hole tighten up and be close to rubber tube and act on the sheath of stube cable, can utilize rubber tube that stube cable is sealed, prevent because the existence in slit and possibly cause the intrusion of water or moisture.In addition, owing to be fit to adopt banded rubber bodies to seal, therefore, its closure is better grasped, and can make it have more surplus, plays better sealing function.

In the such scheme, the outside of sheath is formed with bulge loop, and the inboard corresponding position of two ring-shaped articles forms groove, and bulge loop is arranged in groove.Because the setting of bulge loop and groove makes sheath and two ring-shaped articles have relatively-stationary position relation.

Fig. 2 is the structural representation of ring-shaped article among Fig. 1;

Fig. 3 is the structural representation that rubber bodies is wound into rubber tube among Fig. 1;

Fig. 4 is the structural representation of sheath among Fig. 1.

Embodiment

Be described in detail below in conjunction with the structure of accompanying drawing the utility model:

With reference to Fig. 1-shown in Figure 4, the cable sealing device of this execution mode comprises the ring-shaped article 1 of two semi-involutions; Ring-shaped article 1 all is formed with widthwise edge along 11 in the edge at two ends along laterally stretching out, and the edge along continuous straight runs of ring-shaped article 1 in a side stretches out and be formed with horizontal edge 12; On widthwise edge edge 11, have involutory hole 11a, on horizontal edge 12, have installing hole 12a; A rubber tube 2 of reeling and forming by its inboard fit of 1 pair of circular hole that is encircled into of two ring-shaped articles by the rubber bodies of band shape; Fit the sheath 3 of a tubulose in rubber tube 2, is formed with bulge loop 31, two ring-shaped articles 1 inboard corresponding position in the outside of sheath 3 and forms groove 13, and bulge loop 31 can be arranged in groove 13; Be linked on cable 7 joints by sheath 3, and bring up another fixed structure by the bulge loop 31 and the bottom that is engaged in rubber tube 2 of groove 13; At last, the size by involutory bolt 4 connects two ring-shaped articles 1 and regulates its hole that surrounds through involutory hole 11a can play the effect of deflation to rubber tube 2, sheath 3, and can this device be fixed on the apparatus casing 6 by construction bolt 5.

Claims
