Description of the drawings
Fig. 1 is the structural schematic diagram of the integral type round electric connector of an embodiment of the present invention.
Fig. 2 is the assembling structure schematic diagram of electric connector and cable in Fig. 1.
As shown, wherein corresponding reference numeral is entitled：
1 integral housing, 2 contacts, 3 connector sleeves, 4O type sealing rings, 5 cutting ferrules, 6 grommets, 7 outer wall convex ribs, 8 inner walls
Convex ribs, 9 cables, 10 heads, 11 tail portions, step in 12,13 outer steps.
Specific implementation mode
The present invention is further elaborated below in conjunction with the accompanying drawings.
Integral type round electric connector as shown in Figure 1, it includes integral housing 1, contact 2, connector sleeve 3, cutting ferrule 5
With grommet 6, integral housing 1 is integrally formed by Socket casing and tooth set, since integral housing 1 uses above-mentioned integrated molding
Structure, so split type tooth set round electric connector just has molding simple in compared with the existing technology, production cost is low, efficiency
The advantages that height, product parts are few, while individually Socket casing and tooth set need not be dismantled in disassembly process, so
The efficiency of dismounting electric connector is improved to a certain extent；By 1 one end of integral housing is set as head 10, the other end is set as
Connector sleeve 3 and cutting ferrule 5, connector sleeve 3 are installed in tail portion 11 successively on 1 outer wall upper edge head 10 of integral housing to 11 direction of tail portion
It is equipped with interior step 12 in itself and 1 junction of integral housing, integral housing 1 is equipped with and 12 matched outer step of interior chuck
13, connector sleeve 3 is installed with integral housing 1 by interior step 12 and the cooperation of outer step 13, and interior step 12 and outer step 13 are passed through
Cooperation to ensure being reliably connected for connector sleeve 3 and integral housing 1, cutting ferrule 5 is equipped in itself and 1 junction of integral housing
Bayonet, integral housing 1 are equipped with and buckle matched tail portion chuck, and cutting ferrule 5 passes through bayonet and trailer card with integral housing 1
Platform cooperation installation, by bayonet and the cooperation of tail portion chuck to ensure being reliably connected for cutting ferrule 5 and integral housing 1；In one
Contact 2 and grommet 6 are installed successively along 11 direction of head 10 to tail portion inside sandwich type element 1, in order to realize cable 9 and the present invention
The effect that electric connector is rapidly assembled and disassembled, 6 preferred structure of grommet is as follows, and grommet 6 is made using silicon rubber first,
To make grommet 6 that there is elasticity, then set on 6 outer wall of grommet there are three outer wall convex ribs 7, three outer wall convex ribs 7 are two-by-two
Between spacing be 0.5mm, set on 6 inner wall of grommet there are three inner wall convex ribs 8, three inner wall convex ribs 8 between any two between
Away from being 0.3, by the way that outer wall convex ribs 7 are arranged, when cable 9 is pushed into, since grommet 6 has elasticity well, grommet 6 will
Elastic deformation is generated, outer wall convex ribs 7 are squeezed towards 1 direction of integral housing, and integral housing 1 just passes through outer wall convex ribs 7 and envelope
Wire body 6 forms transition cooperation, and grommet 6 is firmly fixed in integral housing 1, when to ensure that cable 9 is pushed into, seals line
Body 6 will not be subjected to displacement；By the way that inner wall convex ribs 8 are arranged, and set the spacing between inner wall convex ribs 8 two-by-two to 0.3mm, line
When cable 9 is pushed into, integral housing 1 squeezes grommet 6, so that inner wall convex ribs 8 is contacted with cable 9, cable 9 just passes through inner wall convex ribs
8 realize the cooperation of overflowing excessively with grommet 6, simultaneously because the spacing between inner wall convex ribs 8 is set as 0.3mm, it is just inner wall convex ribs 8
Between the variation of spacing provide enough spaces, spacing becomes between causing inner wall convex ribs 8 simultaneously when cable 9 is pushed into
Change, a resigning can be played the role of to cable 9, so that it may so that cable 9 can be slided successfully out of grommet 6, in one
Three latches are along the circumferential direction evenly distributed on 1 inner wall of sandwich type element, contact 2 with three latches by being fitted to one
Inside sandwich type element 1.
It is in connector sleeve 3 to make cylindrical connector that there is better seal effect, the preferred scheme of the present embodiment one
O-ring seal 4 is equipped between integral housing 1, O-ring seal 4 is mounted on 1 outer wall of integral housing, and the O-shaped pad
The internal diameter of circle 4 is matched with the outer diameter of integral housing 1.
According to one embodiment of present invention, plastics may be used in body sandwich type element 1 or metal is made.
As shown in Fig. 2, with cable to be rapidly assembled and disassembled process as follows by the present invention：
Installation process is that will be crimped first with contact 2 after 9 wire stripping of cable, then by contact 2 and cable 9 according to from circle
The direction on shape electric connector tail portion 11 to head 10 is at the uniform velocity pushed into integral housing 1, is not connect with cable 9 until contact 2
End is inserted into the latch inside integral housing 1, and the present invention realizes cable 9 by the improvement to grommet 6
Specific as follows with the function of cylindrical connector Fast Installation, by being provided with outer wall convex ribs 8 on 6 outer wall of grommet, outer wall is convex
There are spacing between muscle 8, it is provided with inner wall convex ribs 7 on 6 inner wall of grommet, there are spacing between inner wall convex ribs 7, use simultaneously
This kind of elastic material of silicon rubber manufactures grommet 6, in this way when cable 9 is pushed into, since grommet 6 has good bullet
Property, grommet 6 just will produce elastic deformation, and at this moment outer wall convex ribs 7 are squeezed towards 1 direction of integral housing, and integral housing 1 is just
Transition cooperation is formed by outer wall convex ribs 7 and grommet 6, grommet 6 is firmly fixed in integral housing 1, to protect
Demonstrate,prove cable 9 be pushed into when, grommet 6 will not be subjected to displacement, then integral housing 1 to grommet 6 squeeze, make inner wall convex ribs 8 with
Cable 9 contacts, and cable 9 just realizes the cooperation of overflowing excessively with grommet 6 by inner wall convex ribs 8, simultaneously because being deposited between inner wall convex ribs 8
In spacing, spacing changes between causing inner wall convex ribs 8 simultaneously when cable 9 is pushed into, and a resigning can be played to cable 9
Effect, so that it may so that cable 9 can be slided successfully out of grommet 6, cable can quickly be realized by the sliding of cable 9
9 with the installation of round electric connector.
When needing to repair cylindrical connector, it is necessary to be dismantled to it, disassembly process is as follows, will tear open first
1 latch of tool ejector mouth aligning members dismounting end is unloaded, then extracting tool had at the uniform velocity previously been advancing to the position, then by contact 2 and line
Cable 9 is extracted from the position on 1 head 10 of integral housing, can be achieved with dismantling, first by using by plug casing in the present invention
Integrally formed integral housing 1 is covered with tooth, with regard to individually being dismantled without being covered to plug casing and tooth in disassembly process, this
Sample realizes that cable 9 can successfully exist with regard to a degree of speed for improving dismounting, while by the improvement to grommet 6
Sliding in grommet 6, this ensures that smoothly pulling out contact 2 and cable 9 from the position on 1 head 10 of integral housing
Go out, it is only necessary to extract contact 2 and cable 9 in disassembly process, demounting procedure is simple, can thus improve the effect of dismounting
Rate.
The essence of the present invention is described in detail in the above specific implementation mode, but can not be to protection scope of the present invention
It is limited, it should be apparent that, under the inspiration of the present invention, those of ordinary skill in the art can also carry out many improvement
And modification, it should be noted that these improvement and modification are all fallen within the claims of the present invention.
