By above description it is known that in the embodiment shown in fig. 1, by seal assembly 4 to connection cables 5
Targetedly encapsulation process, the connector realize connection cables port junction for progress at electrical connection with connecting contact pin 1
Good sealing property；And due to realizing that the seal assembly 4 of encapsulation process is located at the inside of connector shell 1, the connector is also
Have the advantages that simple and compact for structure.
In another exemplary embodiment of the present disclosure, available in sintering processes for the reliability of connection structure
Specific jig comes the position of fixing seal component 4 and connecting contact pin 2 relative to connector shell 1, thus after sintering processes,
Connecting contact pin 2 can be fixed the specific position inside sintering structure.Correspondingly, the connection of connecting contact pin 2 and connection cables 5
It can be fixed the specific position in the sintering structure.In such manner, it is possible to effectively avoid the core of connection cables 5 in sintering process
In be separated or be broken with connecting contact pin 2, ensure connection structure it is reliable, cable insulating stablize.
In an exemplary embodiment of the disclosure, in order to ensure the stability of connector, connector shell 1 and connector tail
Attached 3 can be attached by laser welding.In yet another exemplary embodiment, connector tail attached 3 is in its one far from connector
Welded by oxyhydrogen flame at end and be fixedly connected with connection cables 5, to increase connection cables and connector tail it is attached between company
Connect reliability.In this embodiment, connector tail attached 3 is designed so that oxyhydrogen flame welding and the sintering in seal assembly 4
Structure separates enough distances, the influence to avoid oxyhydrogen flame welding process high temperature to sintering structure leakproofness.It is possible at some
Realization method in, heat insulation heat proof material can be used to manufacture connector tail attached 5, to reduce the size of connector tail attached 5, phase
It can get the overall compact connector of structure with answering.
In the possible application scene of connector described in the disclosure, connector can be applied to be connected with sensor component
It connects.For example, the left side opening that the output end of sensor component may pass through previously described connector shell 1 is come and connecting contact pin 2
Electrical connection.In an exemplary realization, in order to fix the electrical connection of sensor output and connecting contact pin, laser can be passed through
Connector shell 1 is connected by welding with the shell of sensor component.Technology according to the above disclosure is formed by connection and ensure that
The reliability that cable is connect with sensor component in hot environment and vibration processes, and ensure that stablizing for signal exports.
