Description
Technical field
The utility model relates to a kind of connector, is particularly useful for the connector in the auto navigation platform.
Background technology
At present, along with the continuous progress of science and technology, the integrated circuit utilization in the automobile is more and more, and the circuit that is connected with the connector of integrated circuit also becomes increasingly complex, and plug is frequent, and the bed knife of inserting spring is had higher requirements.General connector directly inserts when assembling, in case misplug, does not have pre-program of inserting, and needs to insert again, causes connector to damage easily.Product percent of pass is low, the assembling difficulty.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of slotting spring and simple, the fixing reliable connector of connector assembling.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of auto navigation connector, comprise connector body and a plurality of slotting spring, connector body is provided with and all slotting springs a plurality of slotting spring hole of corresponding matching one by one, the front side of described connector body be provided with communicate with all slotting spring holes and perpendicular slot and with the supporting latch segment of slot, latch segment is provided with the slotting spring through hole with all corresponding quantity in slotting spring hole that intersect, the middle part of all slotting springs is provided with the groove that cooperates with the latch segment clamping, be arranged with two pairs of tandem preceding resilient barb and back resilient barb on the left and right sides face of described latch segment, connector body is respectively equipped with the front bayonet slot and back draw-in groove that matches with the preceding resilient barb and the back resilient barb of latch segment on the wall of the left and right sides of slot position.
Best described connector body is provided with the elasticity card muscle that matches with preceding resilient barb and back resilient barb at front bayonet slot and draw-in groove position, back, and elasticity card muscle is connected with connector body at two ends up and down.
The utility model is by above-mentioned specific design, its beneficial effect is: a kind of brand-new snap close mode, adopt latch segment will be inserted in the design that the slotting spring in the connector body pins, with traditional directly comparing by the slotting spring of connector body lock, this connected mode of the present utility model has been simplified the structure of mould, reduce the maintenance cost of mould, when connector body and latch segment locking state, the effect of inserting between spring and the connector is big.The two ends of latch segment are provided with resilient barb, utilize preceding resilient barb on the latch segment and the front bayonet slot on back resilient barb and the connector body and back draw-in groove to cooperate can to realize latch segment to the pre-slotting of connector body with lock.The active force of inserting between spring and the latch segment during pre-inserting is smaller, and is in case spring is inserted in wrong plug again, little to the damage of plastic.Reduce cost, improved product percent of pass.Write out falsely in the middle of elasticity card muscle two ends on the connector body are connected with connector body, when connector body and latch segment assemble mutually, can improve the qualification rate of product like this, improved production efficiency than being easier to.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, a kind of embodiment of the utility model auto navigation connector, comprise connector body 8 and a plurality of slotting spring 1, connector body 8 is provided with and all slotting springs 1 two socket spring holes 2 of corresponding matching one by one, the front side of described connector body 8 be provided with communicate with all slotting spring holes 2 and perpendicular slot 7 and with the supporting latch segment 9 of slot 7, latch segment 9 is provided with the slotting spring through hole 11 with all slotting spring hole 2 corresponding quantity that intersect, and it is more bigger than slotting spring hole 2 to insert spring through hole 11.The middle part of all slotting springs 1 is provided with the groove 1a that cooperates with latch segment 9 clampings, be arranged with two pairs of tandem preceding resilient barb 3 and back resilient barb 4 on the left and right sides face of described latch segment 9, connector body 8 is respectively equipped with the front bayonet slot 5 and back draw-in groove 6 that matches with the preceding resilient barb 3 and the back resilient barb 4 of latch segment on the left and right sides wall of slot 7 positions.Described connector body 8 is provided with the elasticity card muscle 10 that matches with preceding resilient barb 3 and back resilient barb 4 at front bayonet slot 5 and draw-in groove 6 positions, back, and elasticity card muscle is connected with connector body 8 at two ends about in the of 10.
Its assembling process is as follows: after lead and 1 crimping of slotting spring were good, the slot 7 interior extremely back resilient barb 4 of earlier latch segment 9 being inserted connector body 8 sticked in the draw-in groove 6 of back, and back resilient barb 4 is pre-slotting state against elasticity card muscle 10.To insert spring 1 this moment and insert spring hole 2, the groove 1a active force of the front portion of latch segment and slotting spring 1 is little, so the pulling-inserting force of inserting between spring 1 and the connector is smaller, in case that the damage of the slotting 1 pair of connector plastic of spring of insertion is extracted again in wrong plug is little.Latch segment 9 is pressed into connector body 8 to preceding resilient barb 3 at last again and sticks in the front bayonet slot 5, preceding resilient barb 4 is against elasticity card muscle 10, and the anterior deep of clamping block 9 inserts in the groove 1a that inserts spring, and spring 1 is inserted in latch segment 9 lockings, and connector is locking state.In the middle of being connected with connector body 8, elasticity card muscle two ends on the connector body 8 write out falsely, latch segment 9 insertion slots 7 are convenient in this design, strengthened the elasticity when resilient barb is inserted connector body 8, like this can be when connector body 8 and latch segment 9 mutual assemblings than being easier to, improve the qualification rate of product, improved production efficiency.
During assembling, because of thinner than the lead of big slotting spring crimping with the lead of little slotting spring crimping, lead is in the upper end of connector body 8, the part lead reaches in the slotting spring hole 2 of connector body 8 during assembling, easily distortion and cause the assembling difficulty, present embodiment is concentrated little slotting spring hole and is arranged in connector body 8 centre positions, connector body 8 upper ends are with little slotting spring bore portion to be arranged to be lower than the connector two ends, shorten connector one end and adorn the length of little slotting spring part, so not only can reduce product cost but also improve production efficiency.
