Description
Technical Field
The utility model relates to an electrical heating membrane connects technical field, concretely relates to electrical heating membrane connection structure.
Background
At present, the longest dimension that the heating film can be made is one meter two by the limitation of manufacturing equipment, but with the development of power battery technology, customer's demand changes, and the heating plate that one meter two is long can not satisfy customer's user demand yet.
For satisfying customer's demand, the mode of adopting on the market is mostly to use the wire rod to weld two heating films in order to reach the purpose of extension, and the insulating mode that the tie point adopted is the silica gel vulcanization and handles. Because wire rod overlap joint and silica gel have certain thickness and hardness after the vulcanization, lead to great and hardness in the position thickness of connecting, be difficult for buckling, when laying in the battery box, often occupy great space, lay the operation inconvenience.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an electrical heating membrane connection structure for solving above-mentioned problem, the utility model provides an among a great deal of technical scheme preferred technical scheme have: the operation is convenient, the thickness is thin after the connection is finished, the arrangement operation of the electric heating film is convenient, and the like, and the technical effects are described in detail below.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a pair of electrical heating membrane connection structure, including first heating film and second heating film, the afterbody of first heating film with be provided with the connecting portion that adopt laser welding between the head of second heating film, the connecting portion outside is provided with the insulating part that adopts PI membrane parcel, the width of insulating part is greater than the width of connecting portion, just the both sides border of insulating part respectively in first heating film and second heating film overlap joint.
Preferably, the width of the connecting portion is 20 mm.
Preferably, the insulating portion has a width of 30mm, and the first heating film and the second heating film are overlapped on both sides of the insulating portion to have the same width.
Preferably, the insulation portion is a vulcanized PI film, and is prevented from being fixed to the outside of the connection portion, the first heating film, and the second heating film by thermosetting.
To sum up, the utility model has the advantages that: 1. the laser welding is adopted to connect the electric heating film, so that the welding reliability and the welding efficiency are high;
2. the PI film is adopted for insulation protection at the outer side of the welding connection point, so that the thickness of the connection point is reduced, bending is facilitated during laying, and connection and installation of the electric heating film are facilitated;
3. the connection structure may be used to connect a plurality of electric heating films to adjust a desired length of the electric heating films.
