Abstract

The utility model discloses an anti-drop structure of a cable conductor S terminal, wherein a neck is arranged in the middle of the S terminal, a bake lite tube is sleeved on the outer surface of the S terminal, a neck is also arranged in the middle of the inner surface of the bake lite tube, the neck in the middle of the inner surface of the bake lite tube is combined and clamped with the neck in the middle of the S terminal, a locating sleeve is arranged on the inner surface of the right end of the bake lite tube, the left end of the locating sleeve is propped against the right end of the S terminal, a jacket top is mounted on the outer surface of the right end of the bake lite tube, the right end of the bake lite tube and the end of the right end of the locating sleeve are compressed tightly by the top of the jacket top, and a jacket mouth is mounted on the outer surface of the left end of the bake lite tube. A neck is designed and arranged in the middle of the S terminal, a neck is designed and arranged in the middle of the inner surface of the external bake lite tube, then the two necks are combined together, mounted in the locating sleeve on the inner surface of the top part of the bake lite tube, and are propped against the S terminal, and the bake lite tube top and the locating sleeve top are compressed tightly by the jacket top, therefore the S terminal can be limited from two directions, so as to prevent the shifting and the dropping from occurring between the S terminal and the cable conductor wire.

Description

Cable S terminal disconnecting prevention structure

Technical field

The utility model relates to a kind of S terminal disconnecting prevention structure cable, is a kind of cable project organization that prevents that cable S terminal from coming off specifically.

Background technology

At present, using cable is engine industry ignition system layout pattern commonly used now with the energy delivery in the ignition coil to spark plug, in certain suitable moment, electronic control unit (ECU) control ignition coil charges, after to be charged the finishing, ignition coil is emitted energy, energy is passed to cable by ignition coil, is passed to spark plug by cable again, and finally forms electric spark in engine chamber, gaseous mixture in the ignition combustion chamber makes the engine acting.Usually its structure is that S terminal (matching with spark plug) directly is connected with cable line body, and pull-out force guarantees by the frictional force between S terminal and the cable.The problem that this structure exists is, under the situation of hot environment or cable ageing of rubber, cable plugged may cause coming off of S terminal.Influence is normal to be used.

Summary of the invention

The purpose of this utility model is to remedy the deficiencies in the prior art, and a kind of compact conformation, reasonable in design is provided, and it is spacing to use the outer bakelite pipe of cable that the S terminal is carried out, and prevents the project organization that the S terminal comes off.

In order to achieve the above object, the technical solution adopted in the utility model is: the middle part of S terminal has draw-in groove, the S terminal outside is with the bakelite pipe, the middle part of bakelite pipe inboard also has draw-in groove, the draw-in groove of bakelite pipe middle inside cooperates chucking with the draw-in groove at S terminal middle part, positioning sleeve is positioned at the inboard of bakelite pipe right-hand member, the right-hand member of the left end of positioning sleeve and S terminal is adjacent to, the sheath top is installed on the bakelite pipe right-hand member outside, the top on sheath top compresses the end of bakelite pipe right-hand member and positioning sleeve right-hand member, and the sheath mouth is installed on the bakelite pipe left end outside.

The utility model has the advantages that:

Because the utility model is at the middle part of S terminal design draw-in groove, outer bakelite pipe middle inside design draw-in groove, two draw-in grooves match, the positioning sleeve of the bakelite pipe inside top of packing into, be close to the S terminal, sheath top compresses bakelite pipe top and positioning sleeve top, so can carry out spacingly from both direction to the S terminal, prevents between S terminal and the cable line body generation play and comes off.

Fig. 2 is the utility model draw-in groove structure partial schematic diagram.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the middle part of the utility model S terminal 2 has draw-in groove, S terminal 2 outsides are with bakelite pipe 3, the middle part of bakelite pipe 3 inboards also has draw-in groove, the draw-in groove of bakelite pipe 3 middle inside cooperates chucking with the draw-in groove at S terminal 2 middle parts, positioning sleeve 5 is positioned at the inboard of bakelite pipe 3 right-hand members, the right-hand member of the left end of positioning sleeve 5 and S terminal 2 is adjacent to, sheath top 4 is installed on the bakelite pipe 3 right-hand members outside, the top on sheath top 4 compresses the end of bakelite pipe 3 right-hand members and positioning sleeve 5 right-hand members, and sheath mouth 1 is installed on the bakelite pipe 3 left ends outside.

Draw-in groove on the utility model S terminal 2 and the bakelite pipe 3 (see figure 2) that matches, upwards carry out drawing if hold the top on sheath top 4, then the draw-in groove place of bakelite pipe 3 is main force part, and pull-out force passed to S terminal 2, thereby effectively reduced stressed between cable line body and the S terminal 2, avoided between line body and the S terminal frictional force not enough, the downward play of terminal and coming off.Hold cable sheath top 4 when needs and peg graft downwards, when cable was installed, positioning sleeve 5 blocked S terminal 2, and will push up 4 thrusts that pass over by sheath and pass to S terminal 2, avoided the S terminal along the cable direction play that makes progress.This kind project organization, restriction S terminal upwards and downward play, thereby prevent S terminal and line body generation play and come off at both direction.

Claims

1. cable S terminal disconnecting prevention structure, comprise S terminal (2), it is characterized in that: the middle part of S terminal (2) has draw-in groove, S terminal (2) outside is with bakelite pipe (3), the inboard middle part of bakelite pipe (3) also has draw-in groove, the draw-in groove of bakelite pipe (3) middle inside cooperates chucking with the draw-in groove at S terminal (2) middle part, positioning sleeve (5) is positioned at the inboard of bakelite pipe (3) right-hand member, the right-hand member of the left end of positioning sleeve (5) and S terminal (2) is adjacent to, sheath top (4) is installed on bakelite pipe (3) the right-hand member outside, the top on sheath top (4) compresses the end of bakelite pipe (3) right-hand member and positioning sleeve (5) right-hand member, and sheath mouth (1) is installed on bakelite pipe (3) the left end outside.
