Abstract
The utility model discloses a joint connecting structure, belongs to electrical element manufacturing, and comprises a joint body, wherein, an axial through-hole is arranged in the joint body; a silica plug, a plastic inserting piece and a central pin passing through the silica plug and the plastic inserting piece are arranged in the through-hole. The joint connecting structure is characterized in that a truncated-cone recessed cavity and a top pressing bevel are arranged on the front end of the plastic inserting piece; the back end of the silica plug is inserted into the truncated-cone recessed cavity and is provided with a pressed bevel that is matched with the top pressing bevel; the welding of the central pin with corresponding welding points produces high temperature, thus causing the joint of the central pin and the silica plug to produce a clearance. The joint connecting structure uses the interaction of the silica plug and the plastic inserting piece, re-pressing the deformed silica plug after being heated to the central pin, thus achieving the sealing and waterproofing effects.
Description
Technical field
The utility model discloses a kind of joint connecting structure, belong to the electric elements manufacturing industry.
Background technology
This joint connecting structure uses as the joint of distributor usually, and distributor is as a kind of electric elements commonly used, daily use is on various electric equipment, and these electric equipments use the requirement of water resistance of butt joint syndeton more and more higher under some environment.Shown in Figure 1A, Figure 1B, the high temperature that existing joint connecting structure produces when welding with circuit board owing to its center needle 5, make silica gel plug 6 and center needle 5 junction deliquescing, silica gel plug 6 will shrink during cooling, and therefore the junction can produce the space, and this has reduced its water-proof function greatly, again because the existing structure limitation of connector, therefore 7 one-tenth edged surface combinations always of silica gel plug 6 and plastic cement plug connector can't make because of being heated and produce the waterproof blob of viscose of distortion, compress applying with center needle again.So the joint construction of connector awaits further to improve.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of joint connecting structure is provided, and can make in the syndeton to combine because of the plug that is subjected to thermal contraction compresses with center needle again again, plays the function of water-tight protection against the tide.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following scheme:
Joint connecting structure, comprise joint body, be provided with an axially extending bore in the joint body, be provided with a silica gel plug, plastic cement plug connector in the through hole, with a center needle that passes silica gel plug and plastic cement plug connector, it is characterized in that described plastic cement plug connector front end has the roof pressure inclined-plane of round platform cavity and the described silica gel plug of extruding, described silica gel plug rear end is inserted in the above-mentioned round platform cavity and is provided with the pressurized inclined-plane that matches with above-mentioned roof pressure inclined-plane.
Aforesaid joint connecting structure, some is exposed at outside the through hole to it is characterized in that plastic cement plug connector front of motor.
Aforesaid joint connecting structure is characterized in that described silica gel plug is the elastic silica gel plug.
Aforesaid joint connecting structure is characterized in that described plastic cement plug connector is rigid plastic cement plug connector.
Aforesaid joint connecting structure is characterized in that described through hole one end is provided with one and can limits the positioning step that the silica gel plug moves.
Advantage of the present utility model in sum is as follows:
(1), the utility model adopts silica gel plug and the interactional structure of plastic cement plug connector, reaches the waterproof blob of viscose that makes after the temperature distortion and is close to again on the center needle, plays sealing and good waterproof effect.
(2), the plug connector that adopts of the utility model saves material than traditional plug connector, plays the effect that reduces cost.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As Fig. 2 A, 2B, 3,4,5A, 5B, 6A, joint connecting structure shown in the 6B, comprise joint body 1, be provided with an axially extending bore 2 in the joint body 1, be provided with an elastic silica gel plug 3 in the through hole 2, rigid plastic cement plug connector 4, with a center needle 5 that passes elastic silica gel plug 3 and rigid plastic cement plug connector 4, described rigid plastic cement plug connector 4 front ends have the roof pressure inclined-plane 43 of round platform cavity 42 and the described elastic silica gel plug 3 of extruding, described elastic silica gel plug 3 rear ends are inserted in the above-mentioned round platform cavity 42 and are provided with the pressurized inclined-plane 34 that matches with above-mentioned roof pressure inclined-plane 43, during the joint connecting structure assembling, earlier center needle 5 is penetrated in the round platform cavity that is inserted into rigid plastic cement plug connector 4 after elastic silica gel plug 3 is located again and be combined into semi-finished product, this semi-finished product press-in connector through hole 2, up to the positioning step that restriction silica gel plug 3 moves, this moment, rigid plastic cement plug connector 4 one ends still had sub-fraction not to be pressed into through hole 2.
Operation principle of the present utility model: the high temperature that produces when center needle 5 welding endss and the welding of corresponding pad transfers heat to the junction of center needle 5 and elastic silica gel plug 3 by center needle 5, elastic silica gel plug 3 deliquescing of being heated, shrink during cooling, therefore can produce gap 6 at center needle 3 and elastic silica gel plug 3 junctions, rigid plastic cement plug connector 4 is exposed at through hole 2 outer parts firmly is pressed into through hole 2, because elastic silica gel plug 3 is provided with pressurized inclined-plane 34, rigid plastic cement plug connector 4 is provided with roof pressure inclined-plane 43, when rigid plastic cement plug connector 4 is subjected to external force vertically when elastic silica gel plug 3 moves, elastic silica gel plug 3 can be subjected to a power perpendicular to axial direction, therefore elastic silica gel plug 3 reaches the effect of a water-tight to center needle 5 extruding.
As shown in Figure 7, be provided with an axially extending bore 2 in the joint body 1, be provided with the center needle 5 of an elastic silica gel plug 3, rigid plastic cement plug connector 4 in the through hole 2, center needle 5 and circuit board 8 welding, the other end of circuit board 8 and center needle 10 welding, joint body 1 outside is with a water proof ring 6, and the joint body semi-finished product are pressed into a nut outer tube 7, is provided with a water-proof silica-gel plug 9 in the nut outer tube 7.
