Problems solved by technology

When a single contact module is damaged and needs to be replaced, the damaged single contact module needs to be removed after the block is removed as a whole. Since the connector is generally small in size, this greatly improves the maintenance strength and maintenance time of maintenance personnel. , it is more inconvenient to use

Embodiment Construction

[0029] Embodiment 1 of the differential connector of the present invention: as Figure 1-2 As shown, it includes a connector housing 9 and an insulator 93 disposed in the connector housing 9 . The connector housing 9 is a cylindrical structure extending forward and backward, and the front end of the connector housing 9 is provided with a curved groove 90 for connecting with an adapter connector. The outer periphery of the body 9 is provided with thread or bayonet to realize the connection with the adapter connector. The insulator 93 includes a cylindrical body extending forward and backward, and the front end of the cylindrical body is a plug-in terminal. Such as image 3 As shown, the front end of the cylindrical body is provided with four slots extending left and right at intervals. Chip-type differential contacts 2 arranged in a row in the left-right direction are provided. Since the chip differential contacts occupy less space, each slot is provided with a row of chip ...

Abstract

The invention provides a contact module fixing part and a differential connector. The contact module fixing part comprises a body to be arranged at the rear end of an insulator; at least two through channels through which all contacts pass from front to back are arranged in parallel in the vertical direction on the body; inner elastic claws are arranged on left and right sides of each through channel on the body and used for stopping and limiting the rear end of a corresponding contact module in a backward direction; when opening inward in the radial direction, the inner elastic claws can stop and limit the rear end of the corresponding contact module in the backward direction; when closing up outward in the radial direction, the inner elastic claws can get out of the way to the corresponding through channel so that the corresponding contact module can pass through the channel from front to back; therefore, when the contact module is damaged and needs to be replaced, the inner elastic claws corresponding to the damaged contact module and arranged on left and right sides of the corresponding channel are pressed outwards in the radial direction so as to close up to get out of the way to the corresponding channel and then the damaged contact module can be taken out without removing the whole contact module fixing part, thereby reducing the workload and achieving great use convenience.

Description

technical field [0001] The invention relates to a conductive connection device, in particular to a contact module fixing part and a differential connector. Background technique [0002] Differential connectors are mostly used for the transmission of high-speed data signals, and the common differential connectors are rectangular and circular. For example, the Chinese invention patent with application publication number CN103329359A and application publication date of 2013.09.25 discloses a plug connector for differential data transmission, which is a circular differential connector. It includes four signal pairs, that is, differential pairs, and the four differential pairs are insulated from each other through a cross-shaped structure, and are surrounded by a circular body, that is, an insulator, and the insulator is arranged in the connector housing. The contacts of the differential pair of this connector are cylindrical, and each contact occupies a large space, so that the...
