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.

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.

Specific implementation mode
The embodiment of the present invention is as shown in Figure 1, 2, this includes the same of rubber making with the extendible automobile-used protective jacket of hermetic terminal
The core pipe 1 of axis is tightly connected ring 2 and connecting terminal, and core pipe is located at the center of sealing ring, and core pipe and sealed connection ring pass through annular
Film 3 connects, and core pipe shaft core position is equipped with axial main cable-through hole 4, and connecting terminal is circumferentially distributed in around core pipe, connecting terminal
Equipped with the longitudinal direction wire barrel 5 consistent with core pipe axial direction, wire barrel is the metal tube of deformable crimping lead wire, wire barrel
It is equipped with the plastic column 6 for coating its stage casing, plastic column stage casing is equipped with the annular convex platform 7 projected radially outwardly, annular convex platform cladding
It is linked together in annular film and with annular film, the both ends of wire barrel are respectively distributed to the both sides of annular film, and both sides connect
Spool is connected separately with closure, blocks and is equipped with the outer diameter closure stick 8 equal with wiring bore for being inserted into wiring pipe end, can be with
