Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit device suitable for use in, for example, a high frequency circuit of a satellite broadcast receiving tuner device.

[0002]

2. Description of the Related Art For example, in a high-frequency circuit of a satellite broadcast receiving tuner device, a shield case for covering a circuit board is provided for the purpose of preventing leakage of a high-frequency signal. The entire circuit device covered by such a shield case is mounted on, for example, a parent board and operated. Therefore, in a conventional circuit device, for example, a configuration as shown in the three views of FIG. 2 has been used.

That is, in FIG. 2, an L-shaped connector 22 is mounted on a circuit board 21. The L-shaped connector 22 has a structure in which, for example, a metal lead terminal 23 is bent, and both ends of the connector 22 project from two surfaces of a resin mold 24, for example. And this lead terminal 23
Is inserted into the through-hole 25 of the circuit board 21, and these are fixed by, for example, solder 26 for mounting.

Further, the other end of the lead terminal 23 is disposed so as to protrude from the edge of the circuit board 21. The surface of the resin mold 24 on the side opposite to the circuit board 21 is in contact with one end of the shield case 27, and the surface of the circuit board 21 on the side opposite to the resin mold 24 is the other end of the shield case 27. Abuts the part. Thus, the circuit board 21 and the connector 22 are positioned with respect to the shield case 27.

In this device, one or the other end of the lead terminal 23 is connected to a parent board (not shown).
And the connection is made. That is, when connected using one of the lead terminals 23, the circuit device is mounted with the circuit board 21 parallel to the parent board, and when connected using the other of the lead terminals 23, the circuit is mounted. The circuit device is mounted with the substrate 21 perpendicular to the parent substrate.

[0006]

However, in the above-described device, the L-shaped connector 22 is formed by bending a metal lead terminal 23, for example, so that the positions of both ends of the lead terminal 23 can be stabilized. Can not get to. For this reason, there is a possibility that the work of assembling the circuit device in which one end of the lead terminal 23 is inserted into the through hole 25 of the circuit board 21 or the work of mounting this circuit device on the parent board may not be easily performed.

That is, when assembling the above-described apparatus, one end of the lead terminal 23 is inserted into the through hole 25 of the circuit board 21 as shown in FIG. 3, for example. , A large number of metal rods are arranged in, for example, two rows. Therefore, if the positions of the end portions of the lead terminals 23 fluctuate, it becomes difficult to align these many metal rods with the respective through holes 25.

Similarly, when this circuit device is mounted on a parent board, if the positions of the ends of the lead terminals 23 fluctuate, these many metal rods are aligned with the through holes of the parent board. Becomes difficult. If such an operation is not easy, the manufacturing cost and the assembly cost of the circuit device will increase, and the price of the entire device may increase.

On the other hand, for example, in the above-mentioned satellite broadcast receiving tuner device, the thickness of the device has recently been required to be reduced. For this reason, for example, it is difficult to reduce the thickness of the device by mounting a circuit device in which the circuit board 21 is perpendicular to the parent board using the other of the above-described lead terminals 23. It is becoming mainstream to mount circuit devices with the circuit board 21 parallel to the parent board.

The present invention has been made in view of such a point, and the problem to be solved is that the position of the end of the lead terminal in the conventional device fluctuates. The work or the like when mounting the device on the parent board cannot be performed easily, which leads to an increase in manufacturing cost and an increase in assembly cost, resulting in an increase in the price of the entire device.

[0011]

According to the present invention, a shield case for covering a circuit board is positioned by using a combination of a connector and a fixing socket provided with a straight lead terminal penetrating therethrough. According to this, the variation in the position of the end of the lead terminal is reduced, and the work of assembling the device and mounting the device on the parent board can be easily performed.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, in the present invention, a connector provided with a linear lead terminal penetrating therethrough is mounted on a circuit board, and a fixing socket is disposed on the connector, so that the connector and the socket are connected to each other. The combination is used to position a shield case that covers the circuit board.

In FIG. 1, the front view of A and the top view of B only show the combination of the connector and the socket, respectively, and the side view of C also shows a circuit board and a shield case described later.

In FIG. 1, for example, a linear connector 3 is used in which a linear lead terminal 2 is provided to penetrate a separable resin member 1. That is, in the linear connector 3, one end of the linear lead terminal 2 penetrates through a circuit board 4 to be described later to reach a parent board (not shown), and the lead terminal 2 on the opposite side. Is formed so as to protrude at the other end. Then, the lead terminals 2 of the linear connector 3 are inserted into the through holes 5 of the circuit board 4, and these are fixed by, for example, solder 6 for mounting.

A fixing socket 7 is arranged for the linear connector 3. That is, in this socket 7,
For example, holes 8 respectively corresponding to the other ends of the lead terminals 2 protruding on the opposite side of the above-described linear connector 3 are provided,
The other end of the lead terminal 2 is inserted into these holes 8 so as to be arranged on the linear connector 3. When the socket 7 is formed of, for example, resin, the other end of the lead terminal 2 inserted into the hole 8 is pressed and held. In the illustrated example, each of the sockets 7 is provided with four holes 8 at the other end of the four rows of lead terminals 2.

That is, in this device, one end of the shield case 9 is inserted into the groove 11 of the portion 10 of the socket 7 so that the shield case 9 and the connector 3 are connected.
And the horizontal positioning of the circuit board 4 is performed. The lower surface of the portion 10 of the socket 7 and the bottom surface of the resin member 1 of the connector 3 are flattened by the step portion 12. Then, the other end of the shield case 9 is brought into contact with the flat surface via the circuit board 4, thereby positioning the shield case 9, the connector 3 and the circuit board 4 in the vertical direction.

In this case, by making the lead terminal 2 of the connector 3 straight, the lead terminal 2 can be formed as a relatively rigid body, and the machining accuracy between the resin member 1 and the lead terminal 2 can be improved. Can be higher.

Therefore, in this device, the position of the shield case covering the circuit board is determined by using a combination of the connector and the fixing socket, which are provided with the linear lead terminals penetrating therethrough. , The operation of assembling the device and mounting the device on the motherboard can be easily performed.

As a result, in the conventional device, the position of the end of the lead terminal fluctuates, which makes it difficult to assemble the device or to mount the device on the mother board, thereby reducing the manufacturing cost. According to the present invention, it is possible to easily solve those problems that have caused problems such as an increase in the price of the entire apparatus due to an increase in the cost and assembly cost.

In the above-described device, the linear connector 3, the circuit board 4, and the fixing socket 7 are combined and sandwiched by the shield case 9, so that the connector 3 floats when mounted on the circuit board 4. Can be prevented.

Further, in the above-described device, since the fixing socket 7 is a separate component, an inexpensive general-purpose board connector can be used as the connector 3.
