Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment one of connector assembly of the invention, as shown in Figure 5 to Figure 6, including connector 1 and being connected to connects
The anti-back protective case 11 of the tail end of plug-in unit 1.The structure of connector 1 is as shown in Figures 1 to 4, and the tail end of connector 1 is rectangle, tail end
It is connected with connection terminal 2, a plurality of signal wire 3 is connected on connection terminal 2, the other end of a plurality of signal wire 3 pools harness 4.
The structure of anti-back protective case 11 is as shown in Figure 7 to 10, is made of first pair of body contact 13 and second pair of 14 two parts of body contact, first pair
Body contact 13 is identical with second pair of 14 structure of body contact, sets grab on one side in the part that first pair of body contact 13 and second pair of body contact 14 dock
8, another side sets fixture block 12, makes grab 8 on first pair of body contact 13, fixture block 12 and fixture block 12, grab 8 on second pair of body contact 14
Corresponding matching realizes clamping, and connection is compact, convenient for splitting.Middle part, which is formed, after first pair of body contact 13 and second pair of body contact 14 dock uses
In the cavity passed through for harness 4, cavity includes rectangular inner cavity section 15 and round cavity section 16, and the opening of rectangular inner cavity section 15 is constituted
The opening of connector card interface 6 for being clamped with connector 1, round cavity section 16 is constituted for harness 4 to be fixed
Harness card interface 5 is connected between rectangular inner cavity section 15 and round cavity section 16 by 9 transition of horn transition section, horn transition section 9
It is become narrow gradually from connector card interface 6 to harness card interface 5, is gradually reduced the shaking range of signal wire 3, to gradually weaken letter
Number line 3 shakes pullling of generating.It is set on the inner wall of first pair of body contact 13 and second pair of body contact 14, at connector card interface 6
There is the card slot 7 for being clamped with connector 1.
When installation, as shown in figure 11, first pair of body contact 13 and second pair of body contact 14 are clamped according to arrow direction, when hearing
" " a sound when, illustrate to be clamped between anti-back protective case 11 and connector 1 in place, at this time firmly toward two laybacks first to body contact 13
With second pair of body contact 14, can not draw away, meanwhile, the other end and harness 4 of anti-back protective case 11 are also just clamped in place, are clamped in harness
Mouth 5 is wound with 4 contact position of harness electrical adhesive tape 10, it is ensured that is connected firmly.When needing to overhaul connector 1, card is pushed aside with hand
Hook 8 and fixture block 12, hand-held first pair of body contact 13 and second pair of body contact 14 are pulled open to two sides.
In use process, when car body shakes, strength that signal wire and harness shake by anti-back protective case block without
Can be transmitted on the connection terminal in connector, so that effectively preventing connector there is the case where withdraw of the needle, for vehicle power supply and
Signal transmission provides strong guarantee.
In above-described embodiment one, first pair of body contact and second pair of body contact are by buckle clamping, in example 2, can also be with
It is bolted.
In above-described embodiment one, the part that first pair of body contact is docked with second pair of body contact is equipped with grab, another side on one side
It is equipped with fixture block, the grab and fixture block on the corresponding first pair of body contact of second pair of body contact are respectively equipped with fixture block and grab, the first docking
Shell and second pair of body contact are realized by two pairs of grab fixture blocks to be clamped, and in the third embodiment, can also make first pair of body contact and second
Hinged to one end of body contact, the other end is clamped by grab fixture block.
In above-described embodiment one, first pair of body contact and the second docking shell structure are identical, can also be with structure in example IV
Difference, as long as guaranteeing two parts releasable connection, when two-part structure difference, the disadvantage is that needing different molds to distinguish
Process first pair of body contact and second pair of body contact.
In above-described embodiment one, connected between connector card interface and harness card interface by the transition of horn transition section,
In embodiment five, horn transition section can not also be set, connector card interface and harness card interface are directly connected to, such disadvantage
Be cannot well limiting signal line shaking range, thus cannot well disabling signal line shake generate strength.
The specific embodiment phase of the specific embodiment of anti-back protective case of the invention and the anti-back protective case in above-mentioned connector assembly
Together, details are not described herein again.
