Embodiment 1

[0036] The present invention is a miniature rectangular electrical connector, including a general electrical connector, a straight soldering printed board electrical connector, a curved soldering printed board electrical connector, and the electrical connector includes a plug assembly and a socket assembly And connecting accessories, the plug assembly and the socket assembly all include: a shell 1, a base 13, and corresponding contacts, and the two ends of the assembly are provided with connection mounting holes. The electrical connector shell of the present invention is an integral shell 1 including a connection mounting hole. The inner wall of the casing 1 has a position suitable for the base, and the casing also has a connecting installation structure, and the potting end is integrated with the flange of the casing, and no special installation flange 12 is required. See Figure 2A and Figure 7 The shell of the universal electrical connector is provided with anti-slip groo...

Embodiment 2

[0043] Embodiment 2: The overall composition and manufacturing steps are the same as in Embodiment 1, see Figure 2A , the invention not only improves the structure of the flange of the shell and the potting part, but also integrates the potting end and the flange part of the shell, reducing the volume of the shell. The product accessories have also been improved, and the screws in the connecting accessories are designed to be non-falling screws 3, see Figure 4 , the non-falling screw 3 is provided with a card slot 11 along the axial direction, and a middle large stepped hole is arranged in the axial direction in the connection installation hole, and a collar 4 is installed in the stepped hole, see Figure 5A and Figure 5B , when the screw 3 is connected and installed without falling off, the groove 11 of the screw 3 is adapted to the collar 4, which is an interference fit, see Figure 6 . Since the connection mounting hole has more connection space in the axial direction...

Embodiment 3

[0044] Embodiment 3: overall composition and manufacturing steps are the same as embodiment 1, see Figure 9 , this example is a straight soldered printed board type of a small micro-rectangular electrical connector with a pitch of 1.27mm. The invention integrates the potting end and the flange part of the shell, reducing the volume of the shell. For straight solder printed board type electrical connectors in the prior art, see Figure 10 .

[0045] In the actual use process, when the free end of the screw is installed with a nut, in the process of tightening the nut, sometimes the fixed end of the screw also rotates. In the present invention, the screw in the connecting accessory is designed as the anti-rotation screw 7, see Figure 11A , the anti-rotation screw 7 is milled with a flat surface on the outer circle of one end of the internal thread, see Figure 11B Correspondingly, the same flat anti-rotation groove is provided at the installation place of the shell 1, or t...

Abstract

The invention relates to a miniature micro-rectangular electric connector which belongs to the field of electronic information elements. The invention performs improvement on the existing micro-rectangular electric connector. A housing of the designed electric connector comprises an overall housing connected with a mounting hole, the inner wall of the housing adapts to a base, the housing further comprises a connecting and mounting structure, the filling and sealing end and a flange part of the housing are integrated into a whole, a flange does not need to be specially mounted; anti-skid grooves are arranged on the upper plane and the lower plane of the housing at the filling and sealing end; an anti-shedding screw and an anti-rotation screw are designed as accessories; in order to adapt to the new standard, a general electric connector, a straight type welding printed plate electric connector and a curved type welding printed plate electric connector which are arranged at a spacing interval of 1.00mm with the contact part are provided. By adopting the miniature micro-rectangular electric connector, the volume is further reduced, the weight is reduced, and the high reliability is ensured. The miniature micro-rectangular electric connector is mainly applied in aviation, spaceflight, electronics, ships, weapons, information industry and other national defense key projects, and can be also widely applied in the technical fields of communication with high reliability, radio equipment and instruments, self-control and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic information. It mainly relates to high-reliability electrical connectors used in aviation, aerospace and other fields, specifically a new type of small, micro-rectangular electrical connector. Background technique [0002] Electrical connectors, referred to as connectors, are widely used common devices among thousands of electronic components, and are also widely used general-purpose devices. Products can be widely used in radar systems, aerospace and communications, etc. Military or civilian fields, but also used in industrial fields such as instruments, automatic control, and communications. [0003] The micro-rectangular electrical connector is a reverse polarity connector, which is a military-grade product among small electrical connectors. Elastic pins are stranded wire pins, stranded wire pins are made of three copper wires as the inner ring, seven elastic copper wires are used as the o...
