Embodiment
In order to improve the water proofing property of external cable, the utility model provides a kind of external cable and image capture device.In this technical scheme, outside by two ends the first seal member and the second seal member are set respectively, with the gap closing between outer quilt and the cable core, can avoid so outside rainwater to infiltrate from the slit of outer quilt and cable core, water resistance is promoted greatly.For making the purpose of this utility model, technical scheme and advantage clearer, below lift specific embodiment the utility model is described in further detail.
As shown in Figure 2, the external cable of the utility model one embodiment comprises:
Outer by 10, be arranged at the periphery of cable core wrapping portion 14;
The first seal member 15 is arranged at outward by 10 near ends of cable core the first exposed parts 12, is contacted by 10 sealings with outer with the first exposed part 12 of cable core;
The second seal member 16 is arranged at outward by 10 near ends of cable core the second exposed parts 13, is contacted by 10 sealings with outer with the second exposed part 13 of cable core.
In technical solutions of the utility model, because outer two ends by 10 arrange respectively the first seal member 15 and the second seal member 16, the first seal member 15 and the second seal member 16 contact with outer the sealing simultaneously with cable core 11 by 10, so just, sealed outer by 10 and cable core 11 between the slit, can avoid outside rainwater from outer by 10 and the slit of cable core 11 infiltrate, water resistance is promoted greatly.External cable of the present utility model can be applicable in the various electric equipments, image capture devices such as video camera, camera, when these equipment are applied to the open air, spliced cable can withstand the baptism of rainwater, greatly prolong useful life, in addition, also for electric equipment provides reliable connection, effectively guaranteed the job stability of electric equipment.
As shown in Figure 4, external cable also comprises: be arranged at outward by the water joint 17 in 10 outsides, comprise:
When screwing nut 19, chucking cover 21 is subjected to the radial pressure crush seal cover 23 of nut 19 to be sealed locking with outer by 10.
In the prior art, joint 27 is fixed on thin braiding webmaster 26 outsides by Shooting Technique, joint 27 is in case fixing just again front and back adjusting, this is so that the versatility of existing spliced cable is relatively poor, for example, for the ball-shaped camera of different model, the joint location of spliced cable also is not quite similar, and adopts same spliced cable obviously can't satisfy.
And in this embodiment, can make sealing shroud and outer sealed locking by screwing nut, thereby water joint is fixed on the position that needs, when needs are adjusted the position of water joint, only need oppositely unscrew nut, make between sealing shroud and the outer quilt more laxly, can carry out the position adjustment to water joint.As seen, the versatility of spliced cable improves greatly, has also further saved the cost of electric equipment.In addition, when water joint is fixedly connected with the structural member of electric equipment, because sealing shroud and outer sealed the contact, the sealing gasket of the other end contacts with the structural member sealing of joint body and electric equipment, therefore, can prevent that rainwater from entering from water joint, waterproof effect is had been further upgraded.
As shown in Figure 3, external cable also comprises: outside by 10 two ends, be filled in outer by 10 and cable core 11 between and fluid sealant 24 between the heart yearn 28 of cable core 11.Its technique effect is: on the one hand, outside by 10 two ends, fluid sealant 24 can with outer by 10 and cable core 11 between the slit and the gap sealing between the heart yearn 28 of cable core 11, it is outer by inside to prevent that like this rainwater from infiltrating from these slits, has further strengthened waterproof effect; On the other hand, fluid sealant 24 can prevent that heart yearn 28 line orders from changing with each heart yearn 28 location of cable core 11, has guaranteed that effectively some have the electrical characteristic of the spliced cable of specific (special) requirements to the line order.
As preferred version, be the outer quilt of injection moulding by 10 outward, material is polyvinyl chloride.Can be close to like this periphery of cable core 11 by the injection mo(u)lding of backguy technique by 10 outward, with each heart yearn 28 location of cable core 11, make that the spliced cable diameter is even, profile is clean and tidy, attractive in appearance.Polyvinyl chloride can be applicable to-40 ℃ to 80 ℃ temperature range, has certain thickness polyvinyl chloride outward by corrosion-resistant, ageing-resistant, anti-damage, can be applicable in the comparatively abominable outdoor environment.
The type of the first seal member 15 and the second seal member 16 is not limit, and material can be silica gel or rubber etc., and in the utility model embodiment, the first seal member 15 is preferably injecting head, and the second seal member 16 is preferably heat-shrink tube.Injecting head is through injection mo(u)lding, and heat-shrink tube is through the pyrocondensation moulding, and the sealing effectiveness of these two kinds of seal members is all fine, and fitted seal glue 24 and injection moulding are outer by 10, can further guarantee the line order of cable core 11 each heart yearn 28.
Spliced cable embodiment illustrated in fig. 2 can assemble and be connected with ball-shaped camera as follows:
Form the outer by 10 of parcel cable core 11 by backguy technique, and peel off certain-length at two ends respectively as required, expose the first exposed part 12 and the second exposed part 13;
Outside by 10 two ends, outwards by 10 and cable core 11 between and break fluid sealant 24 between the heart yearn 28 of cable core 11;
Formed injecting head (i.e. the first seal member 15) by the 10 end injection mouldings near cable core the first exposed part 12 outside;
Put heat-shrink tube (i.e. the second seal member 16) and pyrocondensation is fixed by 10 near ends of cable core the second exposed parts 13 outside;
Outside by on 10, adjust the position and screw nut 19 water joint 17 is fixing water joint 17 cover;
It is fixing that the structural member of water joint 17 and ball-shaped camera 25 is threaded io sealing.
The utility model image capture device comprises the external cable of aforementioned arbitrary embodiment.The type of image capture device is not limit, and can for ball-shaped camera etc., have better waterproof effect.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
