Embodiment
For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention and accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.It should be noted that, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment mono-
Refer to Fig. 1 to Fig. 4, embodiments of the invention provide a kind of securing electric lines 11 structures of circuit board housing 1, wherein circuit board housing 1 is plastic shell, it is characterized in that, comprising: be located at the hollow-out parts in circuit board housing 1 and the movable clamping part 2 being oppositely arranged and stationary gripping part 3 in hollow-out parts; Movable clamping part 2 comprises an extension 4 and a jaw 5, one end of extension 4 is connected with the edge of hollow-out parts, the other end coupling hook 5 of extension 4, jaw 5 is provided with the first opening 6, described the first opening 6 is arranged in hollow-out parts back to extension 4 is unsettled, and jaw 5 ends are provided with the elongated portion 7 to downward-extension; Stationary gripping part 3 is provided with the second opening 9, and described the second opening 9 is circular arc, and the second opening 9 arranges with respect to the first opening 6, and second opening 9 back sides of stationary gripping part 3 are connected with the edge of hollow-out parts; The first opening 6 and the second opening 9 form electric wire holddown groove 10.
The circuit board housing 1 that plastic cement is made has certain toughness, can produce certain elastic deformation.Movable clamping part 2 and stationary gripping part 3 are wholely set with circuit board housing 1, straight forming when processing circuit board housing 1, and low production cost, and identical with the material of circuit board housing 1, there is elastically-deformable ability.Because stationary gripping part 3 does not have extension 4, thereby rigidity is higher, and elastically-deformable ability is far inferior to movable clamping part 2.Movable 2 of clamping parts can produce elastic deformation by a relatively large margin owing to having extension 4.Between movable clamping part 2 and stationary gripping part 3, be provided with gap, movable clamping part 2 can be independent movable with respect to stationary gripping part 3.The elongated portion 7 of movable clamping part 2 jaw 5 ends can facilitate staff to strut movable clamping part 2.
During securing electric lines 11, electric wire 11 penetrates from electric wire holddown groove 10, in order to make to agree with mutually between electric wire 11 and electric wire holddown groove 10, and as preferably, the setting that takes the shape of the letter U of described the first opening 6.And then electric wire holddown groove 10 be shaped as arc, while contacting with electric wire 11, be more conducive to contact fully, and can protect electric wire 11.
In order further to improve the protective effect to electric wire 11, as preferably, described the first opening 6 and the second opening 9 surfaces are provided with thickening part 8.Can increase thus the contact area of electric wire holddown groove 10 and electric wire 11, reduce the pressure of 10 pairs of electric wires 11 of electric wire holddown groove, prevent that electric wire holddown groove 10 from crushing electric wire 11.In addition, thickening part 8 is also improved the effect of the first opening 6 and the second opening 9 structural strengths, prevents that the first opening 6 and the second opening 9 from damaging.
The size of electric wire holddown groove 10 is less than the diameter of electric wire 11.Electric wire 11 is in reality fixedly time, and elastic deformation will occur movable clamping part 2, with stationary gripping part 3 dislocation clamping electric wires 11.
To elaborate the operation principle of securing electric lines 11 structures of circuit board housing 1 of the present invention below:
Refer to Fig. 5, when electric wire 11 penetrates electric wire holddown groove 10, because the size of electric wire holddown groove 10 is less than the diameter of electric wire 11, the direction generation elastic deformation must drive activity clamping part 2 penetrating to electric wire 11.After electric wire 11 penetrates electric wire holddown groove 10, between stationary gripping part 3 and movable clamping part 2, be mutual dislocation.And only have when movable clamping part 2 misplaces with stationary gripping part 3, the size of electric wire holddown groove 10 just can be stretched, and produces by this enough spaces and holds electric wire 11.
When staff pulls electric wire 11 intentions to force electric wire 11 to be extracted to opposite direction, movable clamping part 2 is under the drive of electric wire 11 and the effect of self elastic reset active force, to stationary gripping part 3 direction activities.Now the size of electric wire holddown groove 10 is reduced, has further increased the clamping action power to electric wire 11.When staff more firmly pulls electric wire 11, the size of electric wire holddown groove 10 is just more dwindled, just larger to the clamping action power of electric wire 11, thereby has produced the locking phenomenon of electric wire 11 clampings, realizes electric wire 11 self-lockings and fixes.If electric wire 11 need to be pulled out, unique method is exactly that staff is stirred elongated portion 7, first movable clamping part 2 is strutted, then pulls out electric wire 11.
Owing to all having there is to a certain extent elastic deformation in movable clamping part 2 and stationary gripping part 3, in order to improve structural strength, prevent from repeatedly using rear movable clamping part 2 and stationary gripping part 3 to tear damage, as preferably, described extension 4 is provided with fillet with the coupling part at hollow-out parts edge, and described stationary gripping part 3 is provided with fillet with the coupling part at hollow-out parts edge.Fillet structure effectively prevents that stress is concentrated, effectively reduces the risk of tearing damage.
Securing electric lines 11 structures of a kind of circuit board housing 1 provided by the invention, simple in structure, realize electric wire 11 self-lockings and fix, fixing firmly reliable.Securing electric lines 11 structures and circuit board housing 1 are wholely set, and machine-shaping is convenient, low production cost.Simple to operate, be convenient to produce assembling, particularly suitable to batch production assembling, effectively compress assembly cost.Electric wire 11 is had to protective effect, prevent from damaging in fixation procedure electric wire 11.Securing electric lines 11 structural strengths are high, can repeatedly recycle.
The above embodiment has only expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
