Description

Bayonet connector

[technical field]

The utility model relates to a kind of bayonet connector, relates in particular to a kind of bayonet connector that a memory body module is electrically connected to a circuit board.

[background technology]

At present, bayonet connector is installed and fixed to a circuit board, to form the path of signal transmission; One of usual way is through hole solder technology (through hole technology; Be called for short THT), obviously be a bayonet connector like the exposure of Chinese patent CN1291529C, in said bayonet connector; The welding foot of a plurality of terminals is arranged in two rows and is positioned at the both sides of central slot, and the mode through the through hole solder technology between said welding foot and the circuit board is electrical connected.

Along with progress of science and technology and development; Said bayonet connector is the same with other electronic device all to be developed with integrated direction towards becoming more meticulous; Thereby; Spacing between the two said terminals in the said bayonet connector must design more and more forr a short time, becomes more meticulous and integrated development trend to adapt to.So; When the spacing between the two said terminals was too small, the spacing between said welding foot and the said welding foot was correspondingly also very little, thereby; Distance on the said circuit board between the Kong Yukong of the fixing said welding foot of corresponding welding must design very for a short time; In this, will cause a series of difficult problems to overcome, as follows:

One of which; When the distance between the two said holes on the said circuit board is very little; For the corresponding prepackage smoothly of said welding foot is got in the said hole; Must be very high to the requirement of the relative positional accuracy between the two said holes, so, make that the difficulty of producing said circuit board is big, scrappage is high and production cost is high.

They are two years old; The number of electric parts of installing on the in general said circuit board is surprising; Thereby the wiring that is electrically conducted said electronic device is very complicated; And lay to high-density in said hole, and the wiring space on the limited said circuit board is further reduced, and the said circuit board that makes this difficulty connect up undoubtedly makes the matter worse.

At last, when being soldered to said bayonet connector on the said circuit board, can be very little because of the distance between said hole and the said hole, and the scolder in the two adjacent said holes is sticked together, have by short risk to cause said circuit board.

Therefore, designing a kind of new bayonet connector to overcome the problems referred to above, is this area research staff's consistent target.

[utility model content]

To the variety of problems that background technology faced, the purpose of the utility model was to provide a kind of both the adaptation to become more meticulous and integrated trend, made circuit board wiring convenient and produce easily and be difficult for by the bayonet connector of short circuit again.

To achieve these goals; Adopt following technical scheme at the utility model: a kind of bayonet connector; Install and fix to a circuit board, it is characterized in that, comprising: an insulating body; It offers a slot, offers a plurality of accepting grooves respectively in said insulating body and the both sides that are positioned at said slot and is arranged in a row separately; A plurality of the first terminals and a plurality of second terminal; Correspondence is contained in a plurality of said accepting grooves respectively; Be positioned at same row and go up be said second terminal adjacent with each said the first terminal; Each said the first terminal has bottom surface and the perforated mode that one first weld part is revealed in said insulating body and is soldered to said circuit board, and each said second terminal has one second weld part and is revealed in the bottom surface of said insulating body and is soldered to said circuit board through the mounted on surface mode; Wherein, a plurality of said first weld part that is positioned at a plurality of said the first terminals of same row is arranged in a row, and a plurality of said first weld part that is positioned at different rows is not all at same row.

Further, said second weld part that is positioned at same row's a plurality of said second terminal is arranged in a row; Have two said second terminals same row at a distance of between the two nearest said the first terminals, also or same row have said second terminal at a distance of between the two nearest said the first terminals; Said circuit board provides and supplies the fixing a plurality of welding holes of said first weld part welding, and is provided with the fixing a plurality of weld pads of said second weld part welding of confession; More said second weld part of said first weld part is more near said slot; Stating slot offers along the longitudinally of said insulating body; Said the first terminal has one first holding parts and is immobilizated in the said accepting groove; Said first weld part is extended to the longitudinal axis near said slot earlier by said holding parts; Extend to form downwards, said second terminal has one second holding parts and is immobilizated in the said accepting groove again, and said second weld part is extended to form to the longitudinal axis bending away from said slot by said second holding parts; The said accepting groove that is positioned at said slot both sides and is arranged in two rows is about said slot symmetry; Power supply is by said the first terminal conducting; Signal is transmitted by said second terminal.

In the utility model, in the density that does not change said terminal (comprising the first terminal and second terminal) adapting under the prerequisite that becomes more meticulous with integrated development trend, main through following two means to widen the spacing between two said first weld parts:

One of which is positioned at same row and adjacent with each said the first terminal is said second terminal, thereby makes the spacing between same row's two said the first terminals become big, and correspondingly, the spacing between same row's two said first weld parts widens.

Its two, a plurality of said first weld parts that are positioned at different rows are all at same row, are to shift to install, and make that the spacing between difference row's two said first weld parts is also widened.

Above-mentioned two means make the spacing between same row and different rows' two said first weld parts widen; Thereby; Distance on the said circuit board between the two said welding holes of said first weld part of corresponding fixing welding can design greatlyyer; And can be not little because of spacing between the two said welding holes, the position degree requires highly to make said circuit board be difficult to produce, even exists by short risk.

In addition, said second weld part is soldered on the said circuit board through the mounted on surface mode, does not destroy the structure of said circuit board, has promptly reduced the quantity that provides said welding hole on the said circuit board, is beneficial on the said circuit board and connects up.

In sum, the said bayonet connector that the utility model provides had both adapted to and had become more meticulous and integrated trend, made circuit board wiring convenient and produce easily and be difficult for by short circuit again.

Purpose, shape, structure, characteristic and effect thereof for ease of bayonet connector that the utility model is provided all can have further understanding and understanding, combine embodiment and accompanying drawing to elaborate at present.
