Conducting wire and connector contact are bad caused by structure installation is bad or the problems such as damaged occurs for heat-shrinkable T bush.
Realizing the technical solution of above-mentioned purpose is：A kind of heat-shrinkable T bush connection structure, including three conducting wires, it is each described to lead
The first insulating layer is coated with outside line, one end of three conducting wires is separately connected the electrode of corresponding out of phase；Heat-shrinkable T bush,
Including conducting wire fixed part, connector fixing portion, the elastic joint part that is connected between conducting wire fixed part and connector fixing portion with
And the through-hole through conducting wire fixed part, elastic joint part and connector fixing portion；When three conducting wire other ends are at " product " word
Shape is connect across the through-hole with connector and the first insulating layer hot melten type is fixed on the conducting wire fixed part, and the conducting wire is fixed
Portion is squeezed into triangle；The conducting wire fixed part hot melten type is fixed on the connector.
In one preferred embodiment of the utility model, periphery protrusion of the elastic joint part to heat-shrinkable T bush.
In one preferred embodiment of the utility model, the aperture of through-hole is less than the elasticity in the connector fixing portion
The aperture of through-hole in interconnecting piece.
In one preferred embodiment of the utility model, hot melt is coated on the through-hole wall in the connector fixing portion
Temperature is less than the hot melt adhesive layer of connector fixing portion, and the connector fixing portion is heat-fused in the connector by hot melt adhesive layer.
The utility model has the advantages that：The heat-shrinkable T bush connection structure of the utility model, elastic joint part both can conducts
The buffer portion of connector and heat-shrinkable T bush can protect connector when in use；And be conducive to the installation of conducting wire, make to lead
Line has certain receiving space, i.e. conducting wire that can have more part bending in the receiving space in the elastic joint part part,
Accelerate hot melt simultaneously；The hot melting temperature that hot melt adhesive layer is arranged is less than the hot melting temperature of connector fixing portion, in this way, hot melt
When, hot melting temperature need to only be controlled in a certain range, effectively prevent the damage of connector fixing portion.
