Description
Technical field
The utility model relates to a kind of shielding conductor, especially relates to a kind of shielding conductor ground structure.
Background technology
Shielding conductor is wrapped in screen by the heart yearn of one or more insulation coating and the light of a naked coating and forms.Screen is made up of braided metal pipe or spiral winding metal forming, the sheath that outer covering is made up of dielectric resin material.Light that screen wraps up remains with screen and contacts, and in shielding conductor end, light is drawn from screen, and be connected with earth connection ground connection, and then provides the grounded circuit of low resistance for each point on screen.
Shielding conductor ground structure conventional in current production as shown in Figure 1, comprise heart yearn 5 and light 2, and screen heart yearn and light be wrapped in wherein, heart yearn 5 and light 2 are drawn from screen one end, be provided with band glue heat-shrink tube in extraction place, after light 2 is drawn from shielding conductor 1 end, be connected by crimp by means of crimp type terminal and light 2 and earth connection 4 are connected to each other, and be enclosed with on light 2 and be not with glue heat-shrink tube, at light 2 and earth connection 4 junction band glue heat-shrink tube 3.The connecting portion of light 2 and earth connection 4 is covered to protect connecting portion and to ensure the electrical connection between light and earth connection with band glue heat-shrink tube 3.In addition, cover with band glue heat-shrink tube to prevent water from invading equally from shielding conductor 1 exit at light, guard shield line is inner.For being exposed to outside light, using and not being with glue heat-shrink tube to cover to serve as light insulating barrier.
But when light from screen extraction use band glue heat-shrink tube time, heat-shrink tube to shielding conductor one to internal stress.When bending light under this effect of stress, light very easily forms sharp point at leading point place.This sharp point can be worn and torn core insulation, even makes heart yearn inside contact with light, causes short circuit.
In addition, that serves as light insulating barrier is not with glue heat-shrink tube ageing resistace poor, easy-weathering and cause water to infiltrate.
Summary of the invention
The purpose of this utility model is exactly provide a kind of avoid short circuit to overcome defect that above-mentioned prior art exists, prevent the shielding conductor ground structure that seeps water.
The purpose of this utility model can be achieved through the following technical solutions: a kind of shielding conductor ground structure, heart yearn and light are drawn in shielding conductor one end, heart yearn is connected with heart yearn terminal, light is connected with earth connection, the earth connection other end is connected with earth terminal, it is characterized in that, described light is pulled back and is close to shielding conductor exterior insulation sheath after shielding conductor end is drawn, and the light after pulling back is by wrapped with insulation and to be fixed on the insulation sheath of shielding conductor outside.
Described light connects earth connection by crimp type terminal after pulling back, and crimp type terminal is fixed on shielding conductor by wrapped with insulation.
Described light pull back position make earth terminal apart from light from shielding conductor extraction distance the shortest.
Described insulating material is adhesive tape, adhesive tape wrap up exposed light and with light and earth connection junction.
Band glue heat-shrink tube is coated with outside the region that described adhesive tape is wound around.
Above-mentioned shielding conductor ground structure is arranged by the following method:
(1) heart yearn and light is drawn from shielding conductor one end;
(2) be connected with heart yearn terminal by heart yearn, light is connected with earth connection, and the earth connection other end is connected with earth terminal;
(3) light is pulled back and is close to shielding conductor exterior insulation sheath after shielding conductor end is drawn;
(4) light after pulling back is by wrapped with insulation and to be fixed on the insulation sheath of shielding conductor outside;
Described light connects earth connection by crimp type terminal after pulling back, and crimp type terminal is fixed on shielding conductor by wrapped with insulation.
Preferably, light position of pulling back makes earth terminal reach the shortest from shielding conductor extraction distance apart from light.
Described insulating material can be adhesive tape, the region that adhesive tape is wound around outer can also cover tape glue heat-shrink tube to carry out insulation and waterproof infiltration further.
Compared with prior art, the utility model has the following advantages:
Pulling back after light is connected with earth connection avoids the appearance of light from shielding conductor extraction sharp point, solves short circuit problem well.
Pulling back after light is connected with earth connection makes earth terminal distance light extraction place distance reach minimum.
Avoid the use not with glue heat-shrink tube, junction utilizes adhesive tape to be wound around and band glue heat-shrink tube double insulation, waterproof intrusion solve the water infiltration problem of prior art because not causing with the weathering of glue heat-shrink tube.
One need be used at most only to be with glue heat-shrink tube, to use two to be with glue heat-shrink tube not to be with glue heat-shrink tube to compare with one with prior art, effectively reduce shielding conductor ground connection operation man-hour, saved material cost, saved human cost.
