Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a high frequency device, such as a high frequency filter, in which a pin-shaped terminal protrudes from a case side wall, and a method for manufacturing the high frequency device.

<Conventional technology> In high-frequency equipment, pin-shaped terminals (input/output terminals,
In general, high-frequency equipment has a terminal (such as a ground terminal) that protrudes from the side wall of the case, and is connected directly to a circuit board by soldering. Need to adjust.

Therefore, in the above-mentioned type of high-frequency equipment, the high-frequency equipment and measuring equipment have traditionally been connected via a jig.
Its electrical properties and adjustments were made.

This jig has a plug-in connection part for the input/output terminal and the ground terminal of the high-frequency device, and the input/output terminal and the ground terminal of the measuring device are connected to these connection parts. When measuring and adjusting electrical characteristics, high-frequency equipment was crimped onto this jig, and its input/output terminals and ground terminals were connected to the plug-in connections of the jig.

<Problems to be Solved by the Invention> However, the above conventional example has the following problems.

The high-frequency equipment was crimped onto the jig by hand by workers. Therefore, the crimping condition is not constant, the connection condition between the terminal and the connection part changes each time, and the electrical characteristics (
For example, impedance or ground potential) may change slightly, making it impossible to measure or adjust with high reproducibility.

Furthermore, the adjustment work required the operator to press the high-frequency device against the jig with one hand while using the other hand, resulting in poor workability.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a high-frequency device that can measure electrical characteristics with good reproducibility and can perform measurement work with good workability, and a method for manufacturing the same. The purpose is

<Means for Solving the Problems> In order to achieve the above object, the present invention is a high-frequency device having a pin-shaped external terminal protruding from a case, and includes a measurement connector. The high-frequency device is interposed between a high-frequency device and a measuring device for measuring the electrical characteristics of the high-frequency device, and is connected to the external terminal and detachably fixed to the case to constitute the high-frequency device.

In addition, the manufacturing method for high-frequency equipment consists of an assembly process, a connector installation process, a measurement adjustment process, and a connector removal process, and these processes are performed in the stated order. The connector installation process is the process of connecting the measurement connector to the external terminal of the high-frequency device and fixing the measurement connector to the case after the parts have been assembled.The measurement adjustment process is the process of assembling the measurement connector into the case. This is a process of connecting a measurement device to the measurement connector to measure and adjust the electrical characteristics of the high-frequency device, and the connector removal process is a process of removing the measurement connector from the case after the measurement and adjustment of the electrical characteristics are completed. The method for manufacturing a high frequency device is composed of at least the above four steps.

According to the above configuration, during the process of measuring and adjusting electrical characteristics,
The measurement connector will be fixed to the case. Therefore, the connection state between the measurement connector and the high-frequency device is maintained constant, and the electrical characteristics do not change slightly.

Furthermore, since the measurement connector is fixed to the case, the operator can free both hands and perform adjustment work with both hands.

<Example> Hereinafter, the present invention will be described in detail based on an example shown in the drawings. FIG. 1 is a sectional view showing a state in which electrical characteristics are being measured in an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing a state in which a measurement connector is attached.

The high frequency device of this embodiment includes a high frequency device main body 10 and a measurement connector 1. The measurement connector 1 has an outer conductor 2 and an inner conductor 3, and a cylindrical insulator 4 is interposed between them.

The outer conductor 2 also serves as a case song, and has a male threaded portion 2a formed at its negative end. Further, a flange 2b is formed at the other end, and a through hole 5.5 is bored at the end of the flange 2b. Both ends of the internal conductor 3 form a socket-shaped connection part into which a pin-shaped terminal is inserted and connected. Note that reference numeral 6 is a resin that fixes the inner conductor 3 and the insulator 4 to the outer conductor 2.

On the other hand, the high frequency device main body IO has a case 11. This case 11 also serves as an earth terminal for high frequency equipment. In addition, the case 11 has input/output terminals (
External terminal) 12 is inserted and fixed, and its tip 12a
protrudes outward from the case 11. Input/output terminal 1
The fixation of the case 2 is performed, for example, by hermetically processing the terminal 12. Furthermore, a screw hole 13 is bored in the case II. The screw holes 13 are formed at both left and right ends of the protruding portion of the input/output terminal 12, and are formed at positions facing the through holes 5 when the measurement connector 1 is attached.

The measurement connector 1 is detachably attached to the high frequency device main body IO using screws 7. That is, the collar portion 2b
is brought into contact with the case 11. Then, insert the screw 7 into the through hole 5.
Connect the measurement connector 1 by screwing it through the screw hole I3.
is firmly attached to the case 11. At this time, the internal conductor 3 of the connector 1 is inserted and connected to the input/output terminal 12,
The outer conductor 2 of the connector 1 is connected to a case 11, which is a ground terminal of a high frequency device, by a screw 7.

Note that the measurement connector 1 is used only when measuring and adjusting the electrical characteristics of high-frequency equipment. That is, when measuring electrical characteristics, the connector 8 on the input/output terminal side of the measuring device is connected to the measuring connector 1 via the male screw portion 2a, and the measuring device measures and adjusts the electrical characteristics of the high frequency device. Therefore, once the measurement and adjustment are completed, the measurement connector 1 is removed from the case 11.

Next, a method of manufacturing the above-mentioned high frequency device will be explained.

First, components of high frequency equipment are assembled into the case 11.

(Installation process) After that, the measurement connector l is fixed to the case 11 with the screws 7. At this time, the input/output terminal 12 of the high frequency equipment
is inserted through and connected to the inner conductor 3 of the measurement connector l, and the case 11, which also serves as a ground terminal of the high frequency equipment, is connected to the outer conductor 2 of the measurement connector l with a screw 7. (
Connector Attachment Step) Next, the input/output terminal side connector 8 of the measuring device is connected to the measurement connector 1 attached to the case 11. This connection is made by connecting the outer conductor of the connector 8 on the measuring instrument side to the outer conductor 2 of the measuring connector l via the male threaded part 2a. At this time, the inner conductor of the connector 8 on the measuring instrument side Like the terminal 12, it is inserted and connected to the internal conductor 3 of the measurement connector I.

After the high frequency device and the measuring device are connected in this way, the electrical characteristics and adjustment of the high frequency device are performed using the measuring device. (Measurement and adjustment process) After the electrical characteristic measurement and adjustment work of the high-frequency device is completed, the measurement connector l is removed from the case 11. (Connector Removal Process) In the above embodiment, the measuring connector l is fixed and grounded using the screw 7. Therefore, when mounting high-frequency equipment (for example, when mounting on a board)
The screw hole 13 of the case 11 can be used to connect the high frequency device to the board by screws, thereby making it possible to securely mount the high frequency device. Furthermore, if a ground pattern is formed around the screw hole on the board side, it becomes possible to ground the high frequency equipment and the board. Since this grounding is done in the same way as the measurement connector, the grounding reproducibility of high frequency equipment is further improved.

In addition, in the above embodiment, since the connecting connector I has a coaxial connector structure having an inner conductor 3 and an outer conductor 2, impedance matching is good and it is possible to use a considerably high frequency (IOGI (Z or more)). .

Furthermore, in the above embodiment, the mounting structure of the measuring connector on the measuring device side is a screw connection structure using the male threaded portion 2a, but it is not limited to this, and it goes without saying that it may be a plug structure, for example. .

<Effects of the Invention> As described above, according to the present invention, the measurement connector is fixed to the case during the process of measuring and adjusting electrical characteristics. As a result, the connection state between the measurement connector and the high-frequency device is maintained constant, and electrical characteristics do not change slightly during measurement, making it possible to perform measurements and adjustments with high reproducibility.

Furthermore, since the measurement connector is fixed to the case, the operator can free both hands and perform adjustment work with both hands, improving the workability of measurement and adjustment work.

Furthermore, since the measurement connector is detachable, it can be used repeatedly. Therefore, the inconvenience of increasing the cost of the product due to the attachment of the measurement connector does not occur.
