Abstract
The structure is consists of jacket, wire holder, power line, heating element wire and inner framework The method is: the skin of wire head is peeled; the wire is held and fixed at the inner framework; the inner framework and wire is fixed in mould, and is made injection mould to form plastic jacket.
Description
Affiliated technical field
The present invention relates to the electric blanket technical field, be specifically related to a kind of electric blanket power line and joining structure of heating-wire and processing method.
Background technology
Which kind of electric blanket no matter is connected power line in its production process and the insulation protection important procedure that is absolutely necessary with heater element, the quality of this process quality is the key factor of the present commercially available electric blanket product percent of pass of influence.
In existing electric blanket production technology, the method for attachment between power line and the heater element lead generally has following several:
1, heat-shrink tube method: promptly with methods such as welding, clamping connections power line and heater element lead are linked earlier, then plastic protecting casing is carried out insulation protection by the method for thermal contraction to tie-point.
2, electrical adhesive tape insulating method: promptly with methods such as welding, clamping connections power line and heater element lead are linked earlier, with electrical adhesive tape tie-point is carried out insulation protection then.
3, PUR method: promptly with methods such as welding, clamping connections power line and heater element lead are linked earlier, with PUR tie-point is carried out insulation protection then.
4, HF hot melt method: promptly with methods such as welding, clamping connections power line and heater element lead are linked earlier, then the tie-point that is covered with plastic protecting casing is carried out high-frequency heating, make plastic protecting casing and power line, the original plastic insulating layer fusion of heater element lead.
Adopt above-mentioned process, shortcoming such as the contact place of its lead often exists that tensile strength is poor, frangibility, insulation property are low, reliability of technology difference.
Summary of the invention
The purpose of this invention is to provide a kind of have that structure and technology guarantee, contact linking intensity and the reliable electric blanket power line of insulation property and joining structure of heating-wire and processing method.
Realize that technical scheme of the present invention is:
The joining structure of electric blanket power line and heating-wire comprises sheath 1, wire clamp 2, power line 3 and heater element lead 4, it is characterized in that, also comprises liner skeleton 5.
Described liner skeleton 5 is a plastic injection piece, its design feature is, be provided with several in the middle of the working of plastics and have certain axial length, parallel to each other, slightly larger in diameter in the through hole 6 of power line and heater element lead, wall thickness between each through hole 6 has enough electric insulation intensity, and liner skeleton 5 peripheries are provided with several positioning boss of using 7 when sheath 1 injection mo(u)lding.
The processing method that realizes electric blanket power line provided by the invention and the joining structure of heating-wire may further comprise the steps:
The power line 3 that a. will connect is peeled off with the insulation of heater element lead 4 terminations;
B. any one termination in power line 3 or the heater element lead 4 is passed the through hole 6 of liner skeleton 5, the termination of power line 3 with heater element lead 4 linked together, reinforce contacts with wire clamp 2 then, at last contact is moved to the center of through hole 6;
Technique scheme at first tentatively constitutes lead connection and insulation by wire clamp and liner skeleton, then adds a sheath with injection moulding process again, plays the effect of further reinforcement wire joining mechanical strength and insulating reliability.Therefore the present invention makes the machinery of electric blanket power line and heater element lead connection contact and electric property have reliable structure and technology assurance, thereby the electric blanket security of products can greatly be improved, and rate of breakdown obviously reduces.
Description of drawings
Fig. 1 is a structure principle chart of the present invention;
Fig. 2 is the structural representation of liner skeleton of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the joining structure of electric blanket power line and heating-wire comprises sheath 1, wire clamp 2, power line 3 and heater element lead 4 and liner skeleton 5; Liner skeleton 5 is a working of plastics.As shown in Figure 2, liner skeleton 5 structures are very simple, and the axis of each through hole 6 is parallel to each other, its axial length is greater than contact bare wire length, its slightly larger in diameter is in power line and heater element wire diameter, and getting final product by threading, the wall thickness between each through hole 6 has enough thickness; Location when positioning boss 7 is used for sheath 1 injection mo(u)lding in mould.
The processing method that realizes electric blanket power line provided by the invention and the joining structure of heating-wire may further comprise the steps:
The power line 3 that a. will connect is respectively peeled off with the termination of heater element lead 4;
Claims (3)
1, a kind of electric blanket power line and the joining structure of heating-wire comprise sheath (1), wire clamp (2), power line (3) and heater element lead (4), it is characterized in that, also comprise liner skeleton (5).
2, electric blanket power line according to claim 1 and the joining structure of heating-wire, it is characterized in that described liner skeleton (5) is a plastic injection piece, its design feature is, be provided with several in the middle of the working of plastics and have certain axial length, parallel to each other, slightly larger in diameter in the through hole (6) of power line and heater element wire diameter, wall thickness between each through hole (6) has enough electric insulation intensity, and liner skeleton (5) periphery is provided with several positioning boss of using (7) when sheath (1) injection mo(u)lding.
3, a kind of each electric blanket power line in claim 1 or 2 and processing method of the joining structure of heating-wire of realizing is characterized in that may further comprise the steps:
A. the power line that will connect (3) is peeled off with the insulation of heater element lead (4) termination;
B. any one termination in power line (3) or the heater element lead (4) is passed the through hole (6) of liner skeleton (5), the termination of power line (3) with heater element lead (4) linked together, use wire clamp (2) to reinforce contact then, at last contact is moved to the center of through hole (6);
C. liner skeleton (5) and lead are correctly located in mould, form plastic sheath (1) with injection moulding process.
