Description
Technical field
The utility model relates to inductance correlative technology field, refers in particular to a kind of inductance syndeton.
Background technology
Inductor can be the element that magnetic energy stores electric energy conversion.The similar of inductor in transformer, but only has a winding.Inductor has certain inductance, and it only hinders the change of electric current.If inductor is under the state not having electric current to pass through, during circuit ON, it will attempt to hinder electric current to flow through it; If inductor is under the state having electric current to pass through, circuit disconnect time it will attempt maintenance electric current constant.Inductor is also known as choke, reactor, dynamically reactor.Form with wire coiling, there is certain number of turn, the electronic component of certain self-inductance or mutual induction amount can be produced, be often called inductance coil.For increasing inductance value, improving quality factor, reduced volume, often adding iron core or magnetic core that ferromagnetic material makes.The basic parameter of inductor has inductance value, quality factor, self capacity, stability, the electric current passed through and frequency of utilization etc.
Existing inductance is when connecting, general employing be get two wires, be connected with the two ends of inductance respectively, then by the junction of inductance and inductance and wire integrally, at its outer surface cover ordinary hot draw, and heat glue warming to tighten in forward direction heat-shrink tube, finally dry rifle by heat and warm the draw and make it shrink completely.The ordinary hot draw warms that to tighten rear material softer, and do not have good supporting role to the joint line of inductance and wire, after repeatedly bending back and forth and using, inductor wire easily fractures.Although add a certain amount of glue, this step adds manually, can not guarantee again to add that glue is all even not to be trickled down simultaneously, thus the fatigue resistance of the joint line of inductance and wire cannot be ensured completely, there is the hidden danger in reduction motor useful life.
Utility model content
The utility model there is above-mentioned deficiency to overcome in prior art, provides a kind of long service life and safe and reliable inductance syndeton.
To achieve these goals, the utility model is by the following technical solutions:
A kind of inductance syndeton, comprise inductance body and two wires, the two ends, left and right of described inductance body are equipped with a lead-out wire, described lead-out wire is connected with wire, described inductance body and the junction of lead-out wire and wire integrally, are provided with the double wall heat draw outside the junction of described inductance body and lead-out wire and wire.
The connection between firm inductance and wire is carried out by the design of the double wall heat draw.First, eliminate and add glue operation at the mouth of pipe of the ordinary hot draw, less manpower; Secondly, after cooling warmed by the double wall heat draw, have certain hardness, the fatigue resistance of the junction of lead-out wire and wire can well be ensured; Finally, after the cooling of the double wall heat draw, double wall heat draw wall thickness can increase, and better prevents the junction of lead-out wire and wire to leak electricity hidden danger.
As preferably, the junction of described lead-out wire and wire is provided with copper and buckles.By the design of copper button, the security reliability of the junction of lead-out wire and wire can be ensured.
As preferably, the junction of described lead-out wire and wire and copper are buckled and are all adopted wicking mode surface coverage one deck tin.Ensure that the junction of lead-out wire and wire can not be corroded.
As preferably, the outer wall of the described double wall heat draw is the ordinary hot draw, and the inwall of the described double wall heat draw is glue layer, and described glue layer is evenly distributed on the inwall of the ordinary hot draw, and described glue layer adopts PUR to be made.Can ensure that glue is evenly distributed on the junction of inductance body and lead-out wire and wire, make the double wall heat draw after the cooling period, the junction of inductance body and lead-out wire and wire has higher fatigue resistance.
As preferably, the two ends of the described double wall heat draw cover the 3-4mm of two wires respectively.The junction of further protection inductance body and lead-out wire and wire is not impaired.
The beneficial effects of the utility model are: reduce manpower and materials, enhance productivity; Strengthen the fatigue resistance of the junction of lead-out wire and wire, improve useful life; Leak electricity hidden danger in the junction of eliminating lead-out wire and wire; Ensure that the appearance looks elegant of the junction of inductance body and lead-out wire and wire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. inductance body, 2. wire, 3. the double wall heat draw.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as described in Figure 1, a kind of inductance syndeton, comprise inductance body 1 and two wires 2, the two ends, left and right of inductance body 1 are equipped with a lead-out wire, lead-out wire is connected with wire 2, the junction of lead-out wire and wire 2 is provided with copper and buckles, the junction of lead-out wire and wire 2 and copper are buckled and are all adopted wicking mode surface coverage one deck tin, the junction of inductance body 1 and lead-out wire and wire 2 integrally, is provided with the double wall heat draw 3 outside the junction of inductance body 1 and lead-out wire and wire 2.Wherein: the outer wall of the double wall heat draw 3 is the ordinary hot draw, the inwall of the double wall heat draw 3 is glue layer, glue layer is evenly distributed on the inwall of the ordinary hot draw, and glue layer adopts PUR to be made, and the two ends of the double wall heat draw 3 cover the 3-4mm of two wires 2 respectively.
Inductance body 1 and wire 2 by copper snapping well after and wicking, then directly put the double wall heat draw 3 and warm and make it tighten completely.First, eliminate the operation adding glue at the ordinary hot draw mouth of pipe, less manpower, enhances productivity; Secondly, the inner-walls of duct of the double wall heat draw 3, all with one deck glue layer, can guarantee that all even glue of glue is trickled down; Again, after the double wall heat draw 3 is warmed, the glue in glue layer automatically melts and well combines together, has certain hardness after cooling, can well ensure the junction fatigue resistance of lead-out wire and wire 2, improves useful life; Finally, adopt the double wall heat draw 3 after warming and tightening cooling, the double wall heat draw 3 wall thickness can increase, and better prevents the junction of lead-out wire and wire 2 to leak electricity hidden danger.
