Fig. 1 is a schematic view of a transfer tool for a track circuit receiver test according to an embodiment of the present invention.

Labeled as:

1. switching the printed board; 11 and 12, an escape window; a and B, a terminal test area; a1 and B1, patch sockets; a2 and B2, patch plug.

Detailed Description

For the sake of understanding, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, the embodiment of the utility model provides a switching frock is used in track circuit receiver test includes switching printing board 1, has seted up two on the switching printing board 1 and has dodged the window, is dodging window 11 and dodges window 12 respectively, and wherein, the size of dodging window 11 suits with the region of installing components and parts on the SZ board, dodges the region of installing components and parts on window 12's size and the CPU board and suits. Adapter sockets A1 and B1 corresponding to the plugs on the SZ board are arranged beside the avoidance window 11, and the adapter sockets A1 and B1 are 96-core sockets; adapter plugs A2 and B2 corresponding to the sockets on the CPU board are arranged beside the bypass window 12, and the adapter plugs A2 and B2 are all 96-core plugs.

The transfer printed board 1 is further provided with two terminal test areas, namely a terminal test area A and a terminal test area B, test holes for plugging multimeter pens are formed in the terminal test areas A and B, 96 test holes are formed in the terminal test areas A and B respectively, a terminal of the transfer socket A1 and a terminal of the transfer plug A2 are electrically connected with the test holes of the terminal test area A on the transfer printed board 1 in a one-to-one correspondence mode, and a terminal of the transfer socket B1 and a terminal of the transfer plug B2 are electrically connected with the test holes of the terminal test area B on the transfer printed board 1 in a one-to-one correspondence mode.

For example, test hole number 1 in terminal test area a is electrically connected to both terminal number 1 of patch socket a1 and terminal number 1 of patch plug a 2; test hole number 1 in terminal test zone B is electrically connected to both terminal number 1 of patch socket B1 and terminal number 1 of patch plug B2.

When the switching printed board 1 is connected with the SZ board through the switching sockets a1 and B1, the solder points and the test points on the SZ board are exposed from the avoiding window 11, which is convenient for measuring the parameters of the components and the voltages of the test points on the SZ board during the debugging of the whole device.
