Abstract

The utility model relates to an accessory for connecting cables, particularly a sealed pulling-resistant cable connector for connecting the cables, comprising a cable guide connecting pipe 7, a sealing plug 14 arranged in the guide connecting pipe, and an upper pressing ring 13 and a lower pressing ring 6 which are revolvably pressed at the two ends of a sealing plug in the guide connecting pipe by a pressing cover 3. The utility model is characterized in that the middle part of the pressing cover projects upwards to form a pressing line ring, and a thread on the pressing line ring is connected with a clamping ring 2. The utility model has the advantages of simple structure and high pulling-resistant strength, and is particularly suitable to be used in severe environment.

Description

Sealed pulling-resistant cable connector

The utility model relates to the tension sealing cable junctions of a kind of annex of stube cable, particularly stube cable.

In various power circuits, usually need cable and cable, cable and various electrical equipment are reliably connected, to reach the purpose of in various complex environments, electric power safety being delivered to reliably electrical appliance, and at present in humidity, underground, in the water, in the adverse circumstances such as inflammable and explosive, cable connects the normal lead pipe bushing type that adopts, the epoxy resin casting, the plastic, rubber adhesive tape, multiple joints such as draw heat, these joint connection complexity, easily electric leakage, deficiencies such as insufficient strength disclose a kind of sealing detachable electrical cable joint in CN2080238U, it includes cable and connects pipe and sealing plug, the sealing plug two ends have by on the gland spinning in conduit, following pressure ring, though it has remedied the deficiencies in the prior art, easily pull the insufficient strength of stube cable when stressed but still exist.

The purpose of this utility model designs a kind of simple in structure exactly, the tension sealing cable junctions that bonding strength is high.

The purpose of this utility model realizes by following structure; Tension hermetically-sealed cable pull head, include cable and connect pipe and the sealing plug in connecting pipe, the sealing plug two ends have by the upper press ring of gland spinning, following pressure ring in connecting pipe, and its principal character is: gland middle part epirelief forms a line ball ring, and screwed connection has a hold-down ring on the line ball ring; Be connected cable during use and pass gland and line ball ring,, make voltage cable in the line ball ring, the advocating and to act on the hold-down ring of cable tension, but not the joint of two cable junctions by screwing hold-down ring.

The utlity model has simple in structurely, the bonding strength advantages of higher is adapted at using in the various environment.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a line ball ring structure schematic diagram;

Among the figure: 1, stube cable 2, hold-down ring 3, gland 4, boss 5, fluid sealant 6, following pressure ring 7, cable connect pipe 8, RVV 9, internal partition 10, terminals 11, clamping piece 12, line ball ring 13, upper press ring 14, sealing plug.

Below in conjunction with drawings and Examples utility model is further specified:

As shown in Figure 1: the utility model includes cable and connects pipe 7 and the sealing plug in conduit 14, there is upper press ring 13 and the following pressure ring 6 by gland 3 spinning at the sealing plug two ends in catheter tube, it is characterized in that gland middle part epirelief forms a line ball ring 12, screwed connection has a hold-down ring 2 on the line ball ring; Line ball ring upper end has clamping piece 11 to cooperate with conical bolt hole on the hold-down ring, and is more firm with wiring, but the clamping piece indentation is distributed on the line ball ring, as shown in Figure 2; In the gland inside top boss 4 that holds out against upper press ring 13 can be arranged.

Claims
