Problems solved by technology

Due to the limitation of the overall layout of the weapon system, the electrical connector must have a small volume, so that the creepage distance between the contact pairs of the electrical connector and between the contact and the shell is relatively short, making it difficult to further improve the withstand voltage index, especially in Under low pressure ambient conditions, the pressure resistance performance will be further reduced
At the same time, high-current pulses have a great impact on the reliable connection of electrical connectors. Under the repeated impact of high-current, the contact pairs will increase and accumulate continuously due to heat generation, which will eventually lead to failure

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0029] Figure 1a , Figure 1b A schematic structural diagram of a small-volume, high-voltage electrical connector plug 111 designed for the patent of the present invention. The electrical connector plug 111 includes a pin 109, a plug heat-shrinkable sleeve 105, a plug mounting plate 108, a plug housing 107, a spring 106, a rivet 104, a screw 103, a screw cap 102, a plug sealant 110, and a shock plate detonator. The cable 101 is connected to the electrical connector plug 111 by welding with the pin 109 . The material of plug mounting plate 108 is polybutylene terephthalate (PBT) and other engineering plastics, which are used for insulating and fixing the installation position of pin 109; The pads of the cable 101 are welded. The cable 101 can be flat or other shapes. The minimum distance between two pins ...

Abstract

The invention discloses a high-voltage resistant electric coupler plug and socket, a high-voltage resistant electric coupler and manufacturing method of the high-voltage resistant electric coupler. An electric coupler main body is in a two-chip structure and rectangular shape so as to connect with the two electrodes of a slapper detonator flat cable. A locking device of the electric coupler adopts the locking mode of a plug screw and a socket thread so as to reduce the volume. The inner portion of the electric coupler improves the voltage withstanding performance and the overall structural strength through the glue solution encapsulating and special encapsulating technology. A contact pair is in a cleavage groove jack structure and made of beryllium bronze with high tensile strength or other materials so that the working life under the condition of repeated impact of large current pulse can be prolonged. Through the reasonable design and manufacturing technology, the high-voltage resistant electric coupler solves the conflicts of the small volume, the high-voltage resistance of 10 kV, large current pulse and the environmental adaptability, is high in working reliability, and can be applied to special working conditions and the weapon system with the requirement of high reliability.

Description

technical field [0001] The invention relates to the technical field of pyrotechnics and electronic components, in particular to a small-volume, high-voltage and high-current pulse-resistant electrical connector plug, socket, manufacturing method, and electrical connector. Background technique [0002] The shock detonator is the detonating element in the weapon system. Since the shock detonator needs to be detonated under the condition of thousands of volts of high voltage and thousands of amperes of high current pulse, the electrical connector connecting the shock detonator and the safety device must meet high voltage requirements. , High current electrical connection requirements. In addition, electrical connectors also need to adapt to various complex and harsh working environments to adapt to various military environments and military occasions. [0003] At present, the withstand voltage index of electrical connectors for shock detonators is generally not higher than 6kV...
