Problems solved by technology
[0002] At present, the form of the metal package shell is relatively fixed, mainly in the form of UP, UPP, FP, FPP, and PP. The contacts are also mainly made of leads. The outer leads are inserted into the printed board or welded and bonded for signal transmission and housing fixing. Leads are soldered to the chip or bonded with gold wires, which do not support fast plugging and unplugging and may cause varying degrees of damage to the leads after multiple plugging and unplugging
[0003] In the prior art, the shell is usually fixed by screws. Due to the limitation of shell shape and coating, it cannot meet the requirements of quick insertion and removal of flexible pins and the weldability of the shell.

Embodiment Construction
[0013] See attached figure 1 ~ attached figure 2 , the present invention is a metal packaging shell composed of a cover plate 1 and a base 2. The base 2 is provided with a guide post 16 and a rigid socket 12 and a flat lead 13 that can be bonded or welded to the inner and outer end surfaces of the contact piece. The base 2 It is sealed and welded in parallel with the cover plate 1.
[0014] See attached image 3 , the guide column 16 is symmetrically arranged on two cylinders with different diameters on the base 2, and the guide column 16 is welded and fixed by the solder ring and the welding hole 19 of the base 2;
[0015] See attached Figure 4 , the flattening lead 13 is several contacts arranged on both sides of the base 2, the flattening lead 13 is sintered and fixed by the lead glass insulator 15 and the base 2, and the rigid jack 12 is bonded to the gold wire of the flattening lead 13 Parts are treated with gold plating.
[0016] See attached Figure 5 , the rigi...

The present invention discloses a weldable mixed metal package housing used for quick plugging. The package housing is characterized in that a base is provided with guide columns that form a connecting structure with jacks that can be bonded or welded with inner and outer end surfaces of contacts and lead wires; the rigid jacks are fixed with the base in a sintering manner by jack glass insulators; the flattened lead wires are fixed with the base in a sintering manner by lead wire glass insulators; a large excircle of the base is a weldable circumference from which a coating is removed; and gold wire bonding parts of the rigid jacks and the flattened lead wires are processed with a gold-plating process. Compared to the prior art, the weldable mixed metal package housing used for quick plugging has the advantages that quick plugging is supported and no damage is caused to the contacts after multi-time plugging, is simple in structure, good in air-tightness and high in insulation and voltage resistance value, can be directly butted with a flexible needle, and especially satisfies the requirements of quick plugging with the flexible needle and solderability of the housing.
Description
technical field [0001] The invention relates to the technical field of electrical connector packaging shells, in particular to a weldable mixed metal packaging shell for quick plugging and unplugging. Background technique [0002] At present, the form of the metal package shell is relatively fixed, mainly in the form of UP, UPP, FP, FPP, and PP. The contacts are also mainly made of leads. The outer leads are inserted into the printed board or welded and bonded for signal transmission and housing fixing. The lead wire and the chip are soldered or bonded with gold wire, which does not support quick plugging and unplugging, and it is easy to cause damage to the lead wire to varying degrees after repeated plugging and unplugging. [0003] In the prior art, the housing is usually fixed by screws. Due to the limitation of the housing shape and coating, it cannot meet the requirements of quick insertion and removal of the flexible pin and the solderability of the housing. Content...
