[0009] 采用了本发明的一种四脚共面测试装置的技术方案,即在所述测试装置包括电源和并联电路,所述并联电路的一个并联节点设置进行四脚共面测试的四眼插座的技术方案,其技术效果是:可以提高电子元器件制造领域四脚共面测试的效率和准确率。 [0009] The technical solution of the coplanar legs of the test apparatus according to the present invention, i.e., the test device comprises a power source and a parallel circuit in parallel with a node of the parallel circuit is provided four coplanar legs test socket aspect, the technical effect: can improve the efficiency and accuracy of the electronic component manufacturing test coplanar legs.

附图说明 BRIEF DESCRIPTION

[0010] 图1为本发明的一种四脚共面测试装置的电路示意图。 [0010] FIG 1 a circuit schematic diagram of a test device of the coplanar legs of the present invention.

具体实施方式 Detailed ways

[0011] 请参阅图1和图2,为了能更好地对本发明的技术方案进行理解,下面通过具体地实施例,并结合附图进行详细地说明: [0011] Please refer to FIGS. 1 and 2, in order to better technical understanding of the invention, particularly by the following examples, in conjunction with the accompanying drawings and will be described in detail:

[0012] 本发明的一种四脚共面测试装置,包括电源I和并联电路2,所述并联电路2的一个并联节点设置进行四脚共面测试的四眼插座3。 [0012] A coplanar legs test apparatus according to the present invention, includes a power supply circuit and a parallel I 2, a parallel node of the parallel circuit 2 is provided for four coplanar legs 3 test socket.

[0013] 当电子元件的四个引脚四脚共面时,电子元件的四个引脚均匀插接在四眼插座的四个插孔上,所述并联电路导通,当电子元件的四个引脚不是四脚共面时,电子元件的四个引脚无法均匀插接在所述四眼插座的四个插孔上,所述并联电路无法导通。 [0013] When four pins coplanar legs electronic component, the electronic component is uniformly four pins on the plug socket four four jacks, the parallel circuit is turned on, when the four electronic components when the pins are not coplanar legs, four pins of an electronic component can not be uniformly inserted on four of the four socket receptacle, the parallel circuit can not be turned on.

[0014] 因此依据电路的通断,就可以判断电子元件的四个引脚是否是四脚共面的。 [0014] Thus according to the on-off circuit, four pins can be determined whether the electronic component is coplanar legs. 比起传统方法来说,四脚共面测试效率和准确率更高。 Compared to traditional methods, the coplanar legs higher test efficiency and accuracy.

[0015] 为了保护所测试的电子元件不会因为电路短路而被击穿,因此所述并联电路2的两个支路上分别设置第一电阻21和第二电阻22。 [0015] In order to protect the electronic components under test will not breakdown and short circuit, so the two parallel circuit branches 2 are arranged a first resistor 21 and second resistor 22. 当然第一电阻21和第二电阻22也可用灯泡替代,这样观察并联电路的导通和断路更为直观,效率也更高。 Of course, the first resistor 21 and second resistor 22 may also be a bulb replacement, and observe the parallel circuit of the conduction and disconnection is more intuitive and more efficient.
