Description
The utility model relates to printed wiring board electrical testing technical field, more particularly, relates to a kind of novel combined type test punch block.
Conventional printed wiring board pin type electrical measurement test-run a machine is divided into two kinds of plain edition and universal types.The plain edition test machine is low because of the machine valency, test density is higher, and its utilization rate accounts for more than 95%, and its shortcoming is to need to use the special test punch block.Though the universal type test machine does not need the special test punch block, the machine valency is more than medium-sized ten times, simultaneously can't the higher wiring board of test density.Therefore, in very long a period of time, the plain edition test machine will be the main flow equipment of electrical testing in the wiring board industry.Yet the expense of the special test punch block that uses in the plain edition test machine is higher, and wherein, the expense of testing needle accounts for more than 80% of special test punch block cost.
The purpose of this utility model is to provide a kind of combined type that is used for circuit board is tested to test punch block, can overcome the shortcoming of prior art, reduce the manufacturing cost of special test punch block significantly, pass through test module, make that testing needle is not only to be used on the special test punch block, but can be applied in together on a lot of the test punch blocks with the place test module, thereby the expense that makes testing needle is not only to divide on a special test punch block, but can be shared jointly by a lot of testing needle supports.
The following understanding that is based on the utility model realizes that integrated circuit, connector etc. is the main components and parts of installing on the wiring board.And these devices, although there is numerous production firms countries in the world, all seriations of their the encapsulation overwhelming majority, standardization.Therefore these seriations of prefabricated test, the test module of the leg of standardized components and parts according to the needs of wiring board test, is installed on the different testing jigs then.To the test point of a small amount of off-gauge components and parts, if can't the use test module, then available classic method be installed non-removable testing needle, thereby forms a kind of novel combined type test punch block.
The purpose of this utility model is to realize like this, construct a kind of combined type test punch block, comprise base plate 1, be installed in location-plate 2 on the base plate 1 by pillar 3, it is characterized in that, also comprise the test module 5 that can be installed on the described location-plate 2, be provided with module pillar 7 between described test module 5 and the described base plate 1, described test module 5 is provided with testing needle 4 that cooperates with components and parts leg to be measured and the register pin 6 that positions with location-plate, and described location-plate 2 is provided with pilot hole 8 that cooperates with register pin and the instrument connection 9 that cooperates with test module 5 testing needles 4.
Combined type test punch block according to the utility model provides is characterized in that, two register pins 6 are housed on the described test module 5, is used for being positioned at exactly location-plate 2.
Combined type test punch block according to the utility model provides is characterized in that the aperture of corresponding instrument connection 9 is greater than the full-size of testing needle 4 on the described location-plate 2.
Implement combined type test punch block of the present utility model, has advantage simple in structure, easy to use, that cost is low, integrated circuit with one 208 pin is an example, traditional installation method will be installed 208 testing needles, wants line to remove interface connector again, the most skilled technician also must be more than 4 hours, utilize combined type test punch block of the present utility model, the test module of one 208 pin is installed, as long as 1-2 minute.Conservative estimation, the cost of combined type of the present utility model test punch block are the 1/5-1/20 of traditional special test punch block, and work efficiency is better than conventional art greatly.In addition, consume material and also obviously be less than prior art.During combined type of the present utility model test punch block is specially adapted to, the electrical testing of short run wiring board.
In conjunction with the accompanying drawings and embodiments, further specify characteristics of the present utility model, in the accompanying drawing:
Fig. 1 is the structural representation of test punch block in the prior art plain edition test machine;
Fig. 2 is the structural representation of combined type test punch block of the present utility model;
Fig. 3 is the decomposition texture synoptic diagram of combined type test punch block of the present utility model.
Fig. 1 shows the structure situation of traditional test punch block, is connected by pillar 3 between base plate 1 and the location-plate 2, and testing needle 4 is directly installed on the location-plate 2.During test, the stressed location-plate 2 that passes through of testing needle 4 passes on the base plate 1 by pillar 3 again.Testing needle 4 is connected to the circuit part of testing tool by wiring 10 and interface connector 11.
In the combined type test punch block of the present utility model shown in Fig. 2 and Fig. 3, be connected by pillar 3 between base plate 1 and the location-plate 2, test module 5 is by through hole 8 relative being installed on the location-plate 2 on register pin 6 and the location-plate 2, test module 5 is provided with a plurality of testing needles 4, can pass the instrument connection 9 that is arranged on the location-plate 2, electrical testing is carried out in relevant position on the printed circuit board (PCB).After the test of this batch wiring board finishes, then can pull down test module 5, be used for other combined type test punch blocks.
Owing on the test module 5 two register pins 6 are installed, when installing, can be positioned at exactly on the location-plate 2 by them, guarantee the precision of testing.All the full-size than testing needle 4 is big for boring 9 sizes of corresponding testing needle position on the location-plate 2, and the test that makes thin-walled can not have contacting of machinery with location-plate 2 when module is loaded and unloaded, avoided testing needle impaired, has guaranteed the serviceable life of test module.Each test module 5 of combined type test punch block of the present utility model all is equipped with one or several module pillars 7, and during test, the stressed test module 5 that passes through of testing needle 4 passes on the base plate 1 by pillar 5 again.
Except the expense of testing needle can be gone to share by a lot of testing jigs, thereby reduce greatly outside the testing jig cost, time and manpower that the installation of combined type test punch block consumes also significantly are lower than traditional special test punch block.
