Problems solved by technology

[0003] At present, the ordinary hermetic ultra-micro rectangular electrical connector has a pitch of 0.635mm, a row pitch of 1.02mm, a rated current of 1A, a dielectric withstand voltage of 250V, and a mechanical life of 200 times. Only 0.635mm), resulting in poor performance of the connector, rated current is only 1A, dielectric withstand voltage is only 250V, and mechanical life is only 200 times
At the same time, the pin diameter of the contact piece is thin, only φ0.25mm, and the grinding surface cannot be processed on the side of the pin, only the end surface of the pin (area 0.049mm 2 ) for gold wire bonding
2) The existing technology has a large row pitch of contacts (1.02mm), resulting in a large connector size. Taking 37 cores as an example, the length is 18.41mm, the width is 3.81mm, and the height is 5.7mm
3) The existing technology adopts the glass sintering process to seal the metal shell and contact parts with the glass blank. Before the sintering process, the glass blank needs to be processed and shaped. The connector spacing and row spacing are too small to be realized by the glass sintering process. Therefore, the current Larger row spacing of technical connectors

Embodiment 1

[0045] Such as Figure 1 to Figure 4 As shown, the ultra-micro rectangular electrical connector includes a housing 1, a glass base 2 and a plurality of socket contacts 3, and adopts a glass paste filling and sintering process, making full use of the glass paste with strong fluidity and low sintering temperature. Features, can significantly reduce the row distance of the connector, the shell and socket contacts are made of alloy materials, sintered with glass DM308 as a whole, and the leakage rate is not greater than 1.01×10 -3 Pa·cm 3 / S interface seal, figure 1 Among them, the outside of the housing 1 is a stepped rectangular structure 101, and the inside of the housing 1 is a trapezoidal stepped hollow structure 102. A plurality of socket contacts 3 are installed on the glass base 2 in a double row layout, and each row of socket contacts The spacing D1 of 3 is 0.74-0.76mm, and the row spacing D2 of two rows of socket contacts 3 is 0.64-0.66mm.

[0046] In this embodiment,...

Embodiment 2

[0051] In this embodiment, the manufacturing method of the ultra-micro rectangular electrical connector includes the following process steps:

[0052] 1) Soak the housing 1 and jack contact 3 in deionized water for 2-3 hours, then put the housing 1 and jack contact 3 into a filter container, rinse with deionized water, and then rinse with deionized water. Hydroalcoholic dehydration. Preferably, the metal parts (housing, socket) are soaked in deionized water for 2 hours, then put into a filter container, rinsed with deionized water, and then dehydrated with absolute alcohol.

[0053] 2) Put the shell 1 and the socket contact 3 into the vacuum furnace. After the furnace temperature rises to 900-1100°C, the holding time is 40-50min, and the vacuum degree in the vacuum furnace is 6.9×10 -2 -7.1×10 -2 Pa, clean the surface of the shell 1 and the socket contact 3; preferably, put the metal parts into a vacuum furnace, the temperature of the furnace rises to 950-1050°C, the holding...

Abstract

The invention discloses an ultramicro rectangular electric connector and a manufacturing method thereof, and belongs to the technical field of communication, the ultramicro rectangular electric connector comprises a shell, a glass base and a plurality of jack contact pieces, the outer part of the shell is of a step rectangular structure, and the inner part of the shell is of a trapezoidal step hollow structure; wherein the plurality of jack contact pieces are arranged in two rows and installed on the glass base, and the glass base is formed by sintering glass slurry. Compared with an existingstructure, a glass slurry filling sintering process is adopted, the characteristics that glass slurry is high in fluidity and low in sintering temperature are fully utilized, the row distance of the connector can be remarkably reduced, the shell and the jack contact pieces are made of alloy materials and sintered with glass DM308 into a whole, and interface sealing with the leakage rate not largerthan 1.01*10<-3>Pa.cm<3> / S is formed.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to an ultra-micro rectangular electrical connector and a manufacturing method thereof. Background technique [0002] In addition to meeting the general performance requirements, the electrical connector must meet good contact, reliable operation, and easy maintenance. Whether the electrical connector is reliable or not directly affects the normal operation of the circuit and involves the safety of the entire host. For this reason, the host circuit has very strict requirements on the quality and reliability of the electrical connector, and because of the high quality and reliability of the electrical connector, it is also widely used in military systems such as aviation, aerospace, and national defense. [0003] At present, the ordinary hermetic ultra-micro rectangular electrical connector has a pitch of 0.635mm, a row pitch of 1.02mm, a rated current of 1A, a diele...
