Problems solved by technology

Therefore, the surface finish of the sealing cavity is highly required (it is the requirement of sealing performance), and there must be a positioning structure. Whether it is an integral molding cavity or a split molding, the processing technology is difficult, and the sealing cavity is easily damaged.

Abstract

Disclosed is an implantable cardiac pacemaker connector sealing structure. An inverted-T shaped cylinder sealing cavity is formed above a mounting hole of a connector of the implantable cardiac pacemaker connector sealing structure. Besides, the small end inner diameter of the sealing cavity is larger than the inner diameter of the mounting hole of the connector. An inverted-T shaped cylinder sealing plug is installed in the cylinder sealing cavity, and the small end outer diameter of the cylinder sealing plug is slightly larger than the small end inner diameter of the sealing cavity, so thatthe small end of the cylinder sealing plug seals the small end of the cylinder sealing cavity. The large end of the cylinder sealing plug is embedded into the large end of the cylinder sealing cavityto achieve positioning. According to the implantable cardiac pacemaker connector sealing structure, a cylinder cavity structure of which the upper end is small and the lower end is large is adopted, so that not only is the sealing performance ensured, but also it is ensured that the sealing plug is not likely to move or fall off because a torque spanner is inserted in or pulled out, and the sealing requirements of the implantable cardiac pacemaker are met.

Description

Technical field: [0001] The invention belongs to the technical field of implantable cardiac pacemaker manufacturing, and in particular relates to a sealing structure of an implantable cardiac pacemaker connecting body. Background technique: [0002] The sealing system of the implantable cardiac pacemaker is the guarantee for the realization of the pacemaker function. If the sealing system of the implantable cardiac pacemaker is unreliable, it will directly affect the transmission of the pacing signal, and in severe cases, it will cause a short circuit between the positive and negative poles of the circuit, which will affect the life of the pacemaker battery. At present, the sealing system of implantable cardiac pacemakers mainly includes two aspects, one is the sealing of the pacemaker shell, which can fully meet the requirements with the current laser welding technology; the other is the sealing of the epoxy top of the pacemaker , The sealing of the epoxy top includes the ...
