When around open end zone 11d elastic ring 11e being installed, each protruding 11f engages with the respective aperture 11h of openend zone 11d, and each protruding 11f protrudes in the openend zone inwards.
Spring-backed quill 13 is made as silicon rubber or other elastic insulating material by flexible insulating material, and has suitable L shaped shape.This spring-backed quill portion within it provides-L shaped cavity.In L shaped cavity, hold casing joint 11.This sleeve pipe 13 comprises joint overcoat 13a, is used to hold casing joint and is used to introduce the cable passage 13b of high-tension cable 12.This sleeve pipe 13 comprises that further one is used to introduce the plug passage 13c of spark plug 5, and the head 5a of spark plug has the shape of ball.Be directed to and introduce plug connecting portion 11b by means of openend zone 11d plug.
In this example, high-tension cable 12 inserts and is pressed among the cable segment connector 11a of casing joint 11, is to be electrically connected between them.Casing joint 11 is held and is kept in the joint overcoat 13a of spring-backed quill 13.Resemble in prior art, this device has constituted plug and has connected.In this case, the elastic ring 11e that installs around plug connecting portion 11b is placed in the groove 13d.
And when the head 5a of spark plug 5 passed through the plug passage 13c introducing of spring-backed quill 13, elastic ring 11e was because head 5a becomes big and strain.Then, when protruding 11f is fit into neck 5b, described neck 5b constitutes between head 5a and spark plug 5 main parts, and at this moment, ring 11e recovers its original shapes.Head 5a is anchored in the plug connecting portion 11b of casing joint 11 like this.
Just as what seen, when head 5a inserts plug connecting portion 11b, the elastic ring 11e groove 13d that packs into.So thick the internal circular surfaces from plug passage 13c of openend zone 11d protrudes inwards.Therefore, even spark plug inserts with incline direction resembling in the prior art, prevent head 5a near or hook plug connecting portion 11b.Because head is spherical in shape, the head 5a of the spark plug openend zone 11d that is easy to pack into is so improved fitting operation.
In addition, when casing joint 11 when spark plug is removed, ring structure can prevent the inappropriate inclination of casing joint 11 effectively, and the latter keeps correct position in joint overcoat 13a.Need not apply any excessive power, casing joint 11 is easy to be released, and prevents its distortion effectively.So just improved disassembling section.

In a second embodiment, groove 13d also has suitable degree of depth L, guarantees to have the gap, so that when packing head 5a into openend zone 11d, elastic ring 11e is expanded.
In a second embodiment, in plug passage 13c, in fact there is not extension.When even spark plug inserts with incline direction in prior art like this, head 5a be prevented near or the feed cutoff pipe joint.This has improved operation in loading procedure.
And owing to guarantee to have the gap, when elastic ring expanded into groove 13d, ring 11e flexibly was out of shape gently.Like this, fitting operation is easy to finish.
When spark plug 5 is removed casing joint 11, groove 13e and the elastic ring 11e groove 13d that packs into because openend zone 11d packs into is so the inappropriate inclination of casing joint 11 is avoided lock out operation to be modified effectively.
And when removing casing joint 11, elastic ring 11e expands into groove 13d.Owing to there is gap there, ring 11e is that elasticity gently is out of shape, and lock out operation is easy to like this.
A third embodiment in accordance with the invention is shown in Figure 15～18.Hollow space 13C has a vertical size S in a lateral direction cable connecting part 11a's.The size S in fact diameter with cable connecting part 11a is identical, and the length contrast of the hollow space 2c in this size and the prior art is quite long.
On the other hand, shown in Figure 15 and 16, the interior angle 13f of spring-backed quill 13 establishes the boundary and has an almost right angle limit between joint overcoat 13a and plug passage 13c.Because in fact the length S of hollow bulb 11c and/or the approximate right angle limit of interior angle 13f do not exist the gap between hollow bulb and interior angle 13f.Because this structure even spark plug 5 inserts with incline direction,, is effectively avoided at the obstruction of the cavity place of hollow bulb 11c plug to openend zone 11d guiding by interior angle 13f.
And, because this structure can prevent casing joint 11 inappropriate inclinations effectively, and in joint overcoat 13a, keep rectifying.This helps avoid and uses excessive power to come separation sleeve pipe joint 11 and head 5a.Therefore, casing joint keeps rectifying in spring-backed quill, and the head 5a of spark plug is easy to separate with casing joint 11, and has avoided their distortion effectively.
This structure, when respectively be used for elastic ring 11e and/or be used for the groove 13d of openend zone 11d and/or during the 13e combination, further improved the correct location of casing joint 11 in joint overcoat 13a.
And then, the interior angle 13f of sleeve pipe 13, the intersection that is provided at joint overcoat 13a and fills in passage 13c shown in Fig. 8 and 9, has in fact formed right-angle side, cuts sectional view from side and watches (the 4th embodiment).This limit has the deviation that is greater than or less than right-angle side.
The existence of right angle interior angle 13f is identical with the effect that above-mentioned hollow space with big S size produces.
Also can make up above-mentioned measure.
Have in fact that the interior angle at right angle also provides an advantage, in order to make known spring-backed quill 3, the intermediate mold element 6 of use must have L shaped integral material, as shown in figure 19.After injection mo(u)lding, intermediary element 6 is pulled out in a kind of pressure mode from sleeve pipe 3.In contrast, spring-backed quill of the present invention has right angle interior angle 13f, and whole intermediary element 6 can be by making in join domain 18 connection firsts 16 and second portion 17, as shown in figure 20.After injection mo(u)lding, first 16 and second portion 17 are pulled out from spring-backed quill along the direction of as shown in figure 20 different arrows.Therefore, intermediary element 6 is pulled out and is easy to and the manufacturing of spring-backed quill can automation.
Also have, in the casing joint of the fifth embodiment of the present invention, be positioned on the opening edge of openend zone 11d and elastic ring 11e shown in Figure 21～24, opposed edges has partly formed the structure of the flange 11g of similar wing.These flanges extend to openend zone 11d from the blind end of plug connecting portion 11b on the circumferencial direction of plug connecting portion 11b.In this structure, the marginal portion and the hollow space 11c that are positioned at the enclosed edge of plug connecting portion 11b form continuously, and have increased the distance between flange 11g and the hollow space 11c.
Relatively, each edge part extends ground at the sidepiece in openend zone and constitutes, so formed the flange 11g of similar wing: when they separate in the enclosed edge comparison of plug connecting portion 11b apart from the time, these flanges 11g is provided with less interval each other.
In this structure, when having prevented that effectively head 5a from entering hollow bulb 11c, produce and block, and the installation of plug 5 is carried out smoothly.
When plug 5 was correctly packed into openend zone 11d, plug head 5a caught by having the flange 11g that increases the surface exactly at circumferencial direction.So this structure has increased restraining force, and the ability that has increased the opposing vibration and impacted.
The correct insertion of 5a from the head and opposing vibration consider that the distance between the opposing flanges 11g is a little preferably short.
Under certain conditions, flange 11g can form the ring of sealing, shown in Figure 25 and 26.In this case, the situation contrast with former can prevent the inappropriate hollow space 11c that packs into of head 5a more effectively.Correct insertion also is an easy to reach.In addition, in case head 5a packs into, also can more firmly keep by the plug connecting portion.
In addition, pipe sleeve joint 11 can not comprise hollow space 11c, as shown in figure 27.In this case, can reach effect same and the advantage that previous embodiment is mentioned.
In known sleeve 13, a bit separate the marginal portion of openend zone 2d, and confining force is enough not big.Therefore, the wearing and tearing bits are installed and are produced in flutter failure.These shortcomings are eliminated effectively by said structure.
