Large-tolerance blind-mating connector and cavity filter

Abstract

The invention relates to a large-tolerance blind-mating connector, and the connector comprises a blind-mating straight-through part and a contact pin seat; a contact pin at the top end of the contact pin seat is inserted into the tail end of the blind-mating straight-through part, so the blind-mating straight-through part can obliquely move along the axial direction and the radial direction of the contact pin seat. According to the large-tolerance blind-mating connector, the blind-mating straight-through and the pin seat are designed in a split manner, so that the blind-mating straight-through can slightly incline up, down, left and right along the pin seat within a certain range, and the tolerance capability is improved; when coaxiality deviation exists between the port connector at the upper end of the cover plate and the fixing hole in the cavity, the port connector and the tap piece can still be connected, and the qualified rate of products is guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of mobile communication, in particular to a large-tolerance blind-plug connector and a cavity filter. 【Background technique】 [0002] In order to prevent the signal leakage of the output port of the radio frequency cavity filter, a blind mate connector has appeared in recent years, and a blind mate connector is used at the output port of the cavity filter, such as figure 1 As shown, the installation sequence is: crimp the blind mate connector 9 to the cavity 1, insert the tail end into the tap piece 10 and then crimp it on the connecting post in the cavity 1, and then screw the port connector 8 through the screw. The form is prefabricated on the cover plate 2, and then the prefabricated semi-finished cover plate 2 is assembled on the cavity 1. During assembly, the pins at the end of the port connector 8 will be crimped into the cavity 1. The blind-mate connector 9 Blind mate connection to the top jack. A...

AI Technical Summary

Problems solved by technology

Although this method is simple in structure, since the blind plug connector 9 is crimped into the cavity 1 through interference, it is in a fastened state, and the port connector 8 is screwed on the cover plate 2 through threads. There is no good tolerance ability between them, and the tolerance ability is very limited only relying on the elastic tolerance of the blind mating connector 9 material itself

However, there is inevitably a coaxiality deviation between the port connector 8 of the cover plate 2 and the fixing hole inside the cavity 1, so in the actual production process, this solution will cause the coaxiality deviation to be greater than the tolerance of the blind mating connector. Cause a high rate of defective products
