Technical field the utility model relates to the switching mould of a kind of printed circuit board test eedle bed and switching motherboard, more particularly, relates to a kind of modulus of conversion that test point via line plate layering switching on the switching motherboard can be connected with the fastener of needle-bar with copper cash.
Background technology in the prior art, the needle-bar of general-using type test machine and the connected mode of switching motherboard have two kinds, the one, the design of switch card modularity, the fastener that welding processing is finished on switching motherboard connects the bed pin, has technology controlling and process and requires shortcomings such as height, processed complex and maintenance difficult; The 2nd, switching motherboard welding electric wire connects bed pin fastener, has shortcomings such as electric wire is many, difficulty of processing is big, processing machine is bulky.
Summary of the invention the object of the present invention is to provide a kind of production process simple, can reduce the test machine cost of manufacture and the printed circuit board test eedle bed that is easy to produce in batches and the switching mould of switching motherboard.
In order to achieve the above object, the utility model provides following technical scheme: design a kind of test machine needle-bar of printed circuit board (PCB) general-using type and the switching mould of switching motherboard, this switching mould comprises fastener (1), guiding insulcrete (2), transit line plate (3), carriage (4) and positioning guide column (5), overlap each other and guiding insulcrete (2) alternately and transit line plate (3) are positioned at the top of carriage (4) and are supported by carriage (4), carriage (4) periphery is evenly distributed with several positioning guide column (5) vertically upward, transit line plate (3) under the positioning guide column (5) and guiding insulcrete (2) overlap each other and alternately from top to bottom, several fasteners (1) pass the via of each plate correspondence position and are with each plate fixedlys connected, each fastener (1) is connected with via on the transit line plate (3) by copper cash, the other end of each copper cash links to each other with the switch card connector (6) that is positioned at transit line plate (3) edge, transit line plate (3) and the guiding insulcrete (2) hole count and the position, hole is identical and the two is spaced, transit line plate (3) number of plies adapts with switching mould test area, each layer transit line plate (3) is provided with the line via with the corresponding quantity of switching motherboard test point, has the pilot hole identical with the test point quantity of test machine on the guiding insulcrete (2).In specific implementation process, described transit line plate (3) is provided with the pilot hole of multiple density by different test area, this pilot hole is in full accord with pilot hole position and hole count on the guiding insulcrete (2), transit line plate (3) is provided with the different numbers of plies by different test area, each layer transit line plate (3) is provided with the via consistent with each layer switch card test point and corresponding one by one with the fastener copper cash and weld and fixedly connected, and goes up fastener until the insulcrete (2) that will lead and all connects.
The utility model technical scheme preferably can be: the via of the via of each layer transit line plate (3) and adjacent layer transit line plate (3) staggers each other.Because switch card test point will be transferred with multilayer transit line plate (3), can only transfer a part of test point and all test points of the via of each layer transit line plate (3) can not have short circuit phenomenon, so the via of the via of each layer transit line plate (3) and adjacent layer transit line plate (3) staggers each other, benefit: preventing that copper cash has short circuit to reach between layer and the layer searches test point easily.
The utility model technical scheme preferably also can be: be close between every group of transit line plate (3) of carriage (4) below and the guiding insulcrete (2), each layer transit line plate (3) has at interval with adjacent layer transit line plate (3).Because each layer transit line plate (3) four limits are equipped with the switching motherboard connector, and connector has certain altitude, collision causes short circuit and the plug of Convenient switch plate between the connector in order to avoid, therefore each layer transit line plate (3) has at interval with adjacent layer transit line plate (3), be convenient for changing switching motherboard, maintenance easily is close between transit line plate (3) and the guiding insulcrete (2), can strengthen whole layer transit line plate intensity.
The utility model technical scheme preferably can also be: the via on each layer transit line plate (3) is divided into four parts according to the switching motherboard test point and links to each other with the switch card connector (6) on transit line plate (3) four limits respectively.Design of Convenient switch printed line road and software control system are write, and can reduce switch stuck point number and area, reduce switching mold integral height, reduce cost of manufacture.
Compared with prior art, the utlity model has simple in structure, make easy, easy to operate, can adapt to the various needle-bars of printed circuit board (PCB) general-using type test machine and the advantages such as switching of switching motherboard.
