Description

Improved printed circuit board connector

The utility model is relevant a kind of printed circuit connector, especially refer to a kind of inside and outside conducting strip that is installed in the connector, has salient point on this inside and outside conducting strip, make it can reach accurate location and spacing unanimity, and use the reverse assembling of a kind of conducting strip can reach the structure improved printed circuit connector of dual-purpose effect.

The scope of application of printed circuit connector is very extensive, and market demand is very big, and the high-accuracy connector of this kind has two kinds of structures at present, and first kind is contact point plate face contact type, for example No. 50945, the Taiwan patent No. and first additional patent thereof; Second kind is contact point section contact, and the main points of section contact are that daughter board inserts the strength of extracting, and it can control the intensity of its strength and conducting strip, the support force when this conducting strip intensity is to increase the daughter board insertion in the volume design of conducting strip.Because the difference of these two kinds of frame modes, the user can specify wherein a kind of because of the needs of its characteristic, yet section contact printing circuit board connector exists many shortcomings on making at present, its contact point because of conducting strip cuts off through punching press, and it is coarse to form contact point, tangent plane and section can present rugged phenomenon, when daughter board inserts and extracts, can scrape meagre Gold plated Layer and the material of one deck that reaches on the daughter board golden finger on the conducting strip contact point, this Gold plated Layer and material can peel off out some impurity after by scratch, contact resistance is strengthened and instability, and then the quality of contact is worsened; Adopt rigid build-in in the path of navigation if conducting strip is packed into, because of body is an injection molding of plastics, its path of navigation has the shrink error, causes too tightly or pine too, makes it be difficult for the build-in tightness that reaches suitable; Because of having bad phenomenon in manufacture process, conducting strip produces again, need to change several pieces conducting strips in the connector, or reinstall when the client explains orally, will extracting, this moment path of navigation to be fixed support by conducting strip big, can't be mounted in when reinstalling in the path of navigation of body, this is a puzzlement greatly; Again, the monolateral salient point of the known conducting strip path of navigation of packing into, whole conducting strip and conducting strip pin can produce the situation of inclination, as the different situation of pin column pitch of oppositely packing into and having conducting strip with same group of conducting strip, the conducting strip that needs at least more than two kinds just can reach the effect that makes its spacing unanimity.

The design people is because the various shortcoming of above-mentioned prior art, and accumulate professional experiences for many years, the spy invents out a kind of structure improved printed circuit connector, commonly use the shortcoming of connector with improvement, it is only reached with the oppositely assembling and reach dual-purpose effect of the single kind of conducting strip, to reduce the conducting strip kind and to reduce the wrong situation of conducting strip pin position dress.

Main purpose of the present utility model provides a kind of structure improved printed circuit connector, make its inside and outside conducting strip two sides be provided with the rectangle salient point and cooperate bigger path of navigation, make conducting strip can be parallel and Vertical Meshing be mounted in the central authorities of path of navigation, can reach conducting strip accurately location and spacing unanimity in the path of navigation of oppositely packing into.

Secondary objective of the present utility model provides a kind of structure improved printed circuit connector, makes its inside and outside conducting strip two sides be provided with the track salient point, makes this track salient point do the elasticity activity in path of navigation central authorities.

Another purpose of the present utility model provides a kind of structure improved printed circuit connector, make it on inside and outside conducting strip, be provided with the arc contact point, this arc contact point can be eliminated matsurface, makes it can not damage the golden finger of conducting strip contact point and scratch daughter board.

Another purpose of the present utility model provides a kind of structure improved printed circuit connector, make its conducting strip structure design adopt two rows to structure slotting, punching out, can reach the effect of material-saving, and still have between conducting strip that punching out is finished and strip two junction, this junction can prevent conducting strip in carrying or following process and manufacture process, touch the distortion or the skew.

A purpose more of the present utility model provides a kind of structure improved printed circuit connector, it can once be packed into simultaneously count the conducting strip that picks up sheet in the body path of navigation, can reach the effect of quick assembling.

Another again purpose of the present utility model provides a kind of structure improved printed circuit connector, make it be provided with the elasticity fitting portion in inside and outside conducting strip both sides, it cooperates three section rank, both sides portion, make the conducting strip upper end can lean against place, body location, and can reach that upper end elasticity embedding is nibbled and the dual function of lower end build-in, this inside and outside conducting strip can repeatedly be extracted again and pack into, and it also can firmly be mounted in the path of navigation.

The purpose of this utility model is realized by following technical scheme.
