Fix on the injection molding and expose in the surface of injection molding through inlaying the shaping with the glass sealing head, and the shaping is fixed in the injection molding to the link of cooperation wire is inlayed, make the injection molding can play fine fixed action to glass sealing head and wire, glass sealing head cooperation intensity is also better when the assembly piece is assembled, and the injection molding also enables the function that the product has the directional bending of pencil, make the product pencil can not appear when bending that the glass sealing head rocks, crooked and expose more sizes, thereby can guarantee that the product has good NTC function, the assembling process of product is also more convenient simultaneously.
Description
Technical Field
The utility model belongs to the technical field of the thermistor technique and specifically relates to indicate an integrative shaping formula NTC thermistor connection structure moulds plastics.
Background
Thermistors are a class of sensitive elements, which are classified into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to their temperature coefficients. Thermistors are typically temperature sensitive and exhibit different resistance values at different temperatures. The positive temperature coefficient thermistor (PTC) has a larger resistance value at higher temperatures, and the negative temperature coefficient thermistor (NTC) has a lower resistance value at higher temperatures.
The matching strength of the existing thermistor connecting structure is not enough when the existing thermistor connecting structure is assembled with an assembly part, so that the existing thermistor connecting structure is easy to deform under stress, the glass sealing head is easy to shake, the glass sealing head is easy to incline or the leakage size is too large when the wire harness is bent in a directional mode, the NTC function is lost, and the existing thermistor connecting structure is not convenient enough during assembly, so that the existing thermistor connecting structure needs to be further improved.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model discloses to the disappearance that prior art exists, its main objective provides an integrative shaping formula NTC thermistor connection structure moulds plastics, and it can effectively be solved current thermistor connection structure and assemble the combining intensity inadequately, and the glass seal head rocks easily, skewly and exposes more sizes to lose the NTC function, and assemble not convenient enough problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an injection molding integrated NTC thermistor connecting structure comprises an injection molding part, a glass sealing head and a lead; the glass sealing head is embedded, molded and fixed on the injection molding part and exposed out of the outer surface of the injection molding part, and a thermistor is arranged in the glass sealing head; the connecting end of the wire is embedded and molded to be fixed in the injection molding part, and the connecting end of the wire is connected with the thermistor in a conduction mode.
As a preferred scheme, the injection molding piece comprises a base and a column part extending upwards from the surface of the upper end of the base, a positioning part is convexly arranged at the bottom of the base, the column part is of a cylindrical structure, and the glass sealing head is positioned at the top end of the column part.
As a preferred scheme, the glass end socket is oval.
As a preferable scheme, the conducting wire is an enameled wire.
Preferably, the wire connecting end is bent.
Compared with the prior art, the utility model obvious advantage and beneficial effect have, particularly, can know by above-mentioned technical scheme:
fix on the injection molding and expose in the surface of injection molding through inlaying the shaping with the glass sealing head, and the shaping is fixed in the injection molding to the link of cooperation wire is inlayed, make the injection molding can play fine fixed action to the link of glass sealing head and wire, glass sealing head cooperation intensity is also better when the assembly piece is assembled, can prevent effectively that the product from taking place to warp, and the injection molding also enables the function that the product has the directional bending of pencil, make the glass sealing head can not appear when the product pencil is bent and rock, crooked and expose more sizes, thereby can guarantee that the product has good NTC function, the assembling process of product is also more convenient simultaneously.
To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
