Description

The present invention relates to a connector, and more particularly to a connector suitable for adjusting and measuring a circuit.

(B) Problems to be Solved by the Prior Art / Invention The prior art will be described with reference to FIG. 2. Terminals 3a and 3 provided between circuit 1 and load 2
b, a connector for short-circuiting the terminals 3a, 3b of the connector 3, M a measuring instrument having a load equivalent to the load 2, 5 a terminal 5b, 5bc, and a terminal 5b Circuit 1
In addition, a terminal 5c is a connector connected to the ground G, and 6 is a connector with a cable 6a for connecting the measuring instrument M to the connector 5.

In the wireless communication device described above, when measuring the power of the load 2, the connector 4 that simply shorts the connectors 3 a and 3 b is removed from the connector 3. The measuring device M is connected via the measuring device M, and the power of the load 2 is measured by the measuring device M.

When the measurement is completed, the connector 4
Terminals 3a and 3b are short-circuited.

However, the above-mentioned conventional one has a configuration using four connectors and four pins, so that the cost is high, and
Since the power can be measured while the connector 4 is connected to the connector 3, there is a problem that a measurement error occurs.

This invention has been made in view of the above points,
An object of the present invention is to provide a connector which is inexpensive and prevents measurement errors.

(C) Means for Solving the Problem The connector of the present invention is provided between the terminal circuit of the radio and the load, and is provided with a single first connection terminal connected to the terminal circuit; A first connector having a second connection terminal connected to the load and a third connection terminal connected to a ground circuit; and a plurality of connection terminals among the connection terminals of the first connector. A second connector connectable to the first connector, and a signal of the first connection terminal is supplied to the second connector via the second connector in accordance with a connection state between the first connector and the second connector. Between the first connection terminal and the third connection terminal, the first connection state being output to the second connection terminal and prohibiting the connection between the first connection terminal and the third connection terminal. And an output signal of the final stage circuit is output, and the first connection terminal is connected to the second connection terminal. The connection terminals are arranged so that a second connection state in which connection with the connection terminals is prohibited can be selected.

(D) Embodiment An embodiment of the connector according to the present invention will be described with reference to FIG.

The same parts as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

In the figure, reference numeral 7 denotes a connector including three pins 7a, 7b, 7c and a support 7d for supporting the pins.

When measuring the output power of the final-stage circuit 1 in the connector configured as described above, the connector 4 shorting the terminals 7a and 7b of the connector 7 is removed from the connector 7, and then the terminals 7b and 7c Is connected to a measuring instrument M via a connector 6, and the output power of the final-stage circuit 1 is measured by the measuring instrument M.

When the measurement is completed, the connector 6 is detached, and the terminals 7a and 7b of the connector 7 are short-circuited again by the connector 4.

(E) Effect of the invention Since the connector according to the invention is configured as described above, the two connectors are not connected at the same time, and the measurement error is eliminated.

In addition, it has excellent features such as simple structure and easy implementation since it can be configured at low cost.
