Description

The band extendible automobile-used protective jacket of hermetic terminal

Technical field

The present invention relates to a kind of automobile assembling parts, more particularly to a kind of extendible automobile-used protection of band hermetic terminal Set.

Background technology

China is auto industry big country and automobile consumption big country, and car ownership is increasing, and automobile has become the people Many indispensable tools often unavoidably will be to vehicle in vehicle service life in order to meet the certain specific demands of driver Carry out upgrading, such as installation burglary-resisting system, warming up system, panorama system, intelligent key system equipment, in this kind of upgrading It will usually be needed to add new electric wiring, these newly-increased electric wires along with the transformation of electric part in transformation process Road generally will reach another space from a space across car body, existing wiring method typically burrow on the car body or Along former vehicle wire harness cabling, all there are certain drawbacks in both methods, body construction certainly will be influenced on the car body by, which burrowing, brings peace Full hidden danger, original vehicle wire harness is all by being connect with car body with the sealing shroud that it is adapted to, to expand sealing when along former vehicle wire harness cabling Set could pass through newly-increased conducting wire, and when expansion is easy for making a mess of sealing shroud, influence the leakproofness of box body, and newly-increased harness Contacted at sealing shroud too closely with former vehicle wire harness, when electric load is larger thermal diffusivity it is bad there are security risks, and Certain electromagnetic interference can be also caused, the Electro Magnetic Compatibility of vehicle is influenced, two methods are all relatively time-consuming in upgrading to take Power is still solved up for technology.

Invention content

To solve the above-mentioned problems, the present invention provides a kind of extendible automobile-used protective jackets of band hermetic terminal.

The technical solution adopted by the present invention is：A kind of extendible automobile-used protective jacket of band hermetic terminal, it is characterised in that including Coaxial core pipe and sealed connection ring and connecting terminal, core pipe are located at the center of sealing ring, and core pipe and sealed connection ring pass through Annular film connection, core pipe shaft core position are equipped with axial main cable-through hole, and connecting terminal is circumferentially distributed in around core pipe, terminals Son is equipped with the longitudinal direction wire barrel consistent with core pipe axial direction, and wire barrel is equipped with the plastic column for coating its stage casing, plastics Column stage casing is equipped with the annular convex platform projected radially outwardly, and annular convex platform is coated in annular film and is linked as one with annular film Body, the both ends of wire barrel are respectively distributed to the both sides of annular film, and both sides wire barrel is connected separately with closure, block to be equipped with and be inserted into The outer diameter of the wiring pipe end closure stick equal with wiring bore blocks stick and is connected with the extension equal with wiring pipe outside diameter Stick, the foundation that wiring pipe end cladding is connected due to annular film, foundation outer end is concordant with wire barrel outer end, and foundation is connected with packet The newel post for extending stick is covered, newel post's outer diameter is less than wire barrel outer end outer diameter.

Further, the extension stick is connected with the plugging cap being exposed at outside newel post.

Further, the sealed connection ring one side, which is equipped with, is connected thereto unitary metallic ring, and becket is connected with circumferential point Cloth passes through the shrapnel for being tightly connected ring another side, and buckle is connected on shrapnel.

Further, the sealed connection ring one side, which is equipped with, is connected thereto unitary metallic ring, and becket outer rim is connected with week To the shrapnel of distribution, buckle is connected on shrapnel.

Sealing protection of the present invention applies mechanically rubber system and is used as to can be used for boxlike component of automobile threading beam, by former fare when vehicle assembles Beam is passed through by the main cable-through hole in core pipe, and main cable-through hole is tightly connected by own resilient and harness, will be tightly connected ring and vehicle Babinet connects, connecting terminal indwelling, and connecting terminal both sides not unicom ensure that the leakproofness of former vehicle, and being transformed in customer upgrade needs It can arrange along former vehicle wire harness direction when adding new circuit, cut annular incision in foundation and newel post's intersection, then extract It blocks, conducting wire end is inserted into the port of wire barrel, then compression bonded line pipe port makes its deformation be electrically connected with conducting wire realization, real Existing babinet passes through, you can ensure the leakproofness of vehicle, and without destroying body construction, the place of passing through possesses spacing with former vehicle wire harness, It can contact that the thermal diffusivity too closely generated is bad at sealing shroud with former vehicle wire harness to avoid newly-increased harness and electromagnetic compatibility Problem, when upgrading, are time saving and energy saving, and wire barrel of the present invention is in sealing state in not enabled always, will not aoxidize and By environmental corrosion, ensure the reliability when later stage enables.
