Compact type secondary connector

Abstract

The invention discloses a compact type secondary connector which comprises screws, hexagon nuts, terminal lugs and a base, wherein the base is of a two-layer step structure, the surface of the upper layer is provided with a mounting groove A and a mounting groove B, the surface of the lower layer is provided with a mounting groove C and a mounting groove D, an L-shaped guide groove is respectively manufactured below each mounting groove inside the base, two guide grooves at each layer are at the same height and staggered horizontally; two guide grooves on each side are staggered vertically soas to ensure mutual independence; a terminal lug is respectively fixed in each mounting groove, one end of each terminal lug is fixed in the mounting groove through the screws, the other end of each terminal lug extends into the corresponding socket along the guide groove. In order to ensure insulation among the four terminal lugs and reach the compact type effect at the same time, the height of each layer of the base is set in accordance with the requirement that the tail end of the screw cannot touch the guide groove, and the width of the base can be set in accordance with the requirement that two mounting grooves on the surface of each layer are mutually independent. The compact type secondary connector provided by the invention has the advantages of compact structure, solid connectionand good usability.

Description

technical field [0001] The invention relates to a connector, in particular to a compact secondary connector, which belongs to the field of electronic technology. Background technique [0002] At present, the secondary connectors on small devices generally do not need screws to fix the wiring parts. Although this kind of secondary connectors has high space utilization rate, it has low reliability and is easy to loosen, so it is not suitable for use on devices with high reliability requirements. For the secondary connectors on large equipment, although the wiring parts are fixed by screws, which can meet the reliability requirements, the space utilization rate is low, and it is not suitable for use on small-volume equipment. Therefore, there is an urgent need for a secondary connector that can meet the dual requirements of reliability and small size. Contents of the invention [0003] In view of this, the present invention provides a compact secondary connector, which has c...
