[0003]

After filing the above-mentioned unknown invention, the present applicant promoted the mass production plan, and the present inventor subsequently conducted a practical application test.

As a result, it was confirmed that the invention of the prior application has a desired effect in practical use as well, but it became clear that improvement is still desired in the adjustment and inspection of products in the mass production process. In FIGS. 4 and 5 showing one embodiment of the invention of the prior application, the feeding end 22 of the λ / 4 exciter 22 is shown.
b is connected to the output end 30 of the radio-frequency unit of the radio main body so that they are always in conduction. Although the above condition is acceptable for the product of the mobile communication device, the following work is required near the final stage in the production factory.

B. The output terminal 30 of the high-frequency unit must be separated from the antenna circuit, connected to a tester (not shown), inspected, and adjusted as necessary.

B. After the above inspection and adjustment, the original condition (Fig. 4,
5).

It is widely practiced in wireless technology to disconnect a part of an electric circuit to insert and connect a tester, and to remove the tester to restore the electric circuit. However, in the mobile phone using the GHz class frequency band, there is a difficult problem that cannot be covered by the conventional technique, and particularly, there is a peculiar problem in connection between the antenna and the high frequency unit. further,
It is required to be small, lightweight and inexpensive. FIG. 6 is an explanatory diagram showing an example in which the high-frequency unit of the antenna device according to an unknown prior application is connected to a tester or an antenna circuit by applying the conventional technique.
At the output end 30 of the radio frequency unit, the measuring connector 3
2 and connect the end 33 of the connecting wire to the feeding end 22b of the exciter.
Are separated from each other. After inserting a plug (not shown) into the measuring connector 32 and connecting the plug to a tester (not shown) and performing necessary inspections and adjustments, the plug (not shown) is removed to remove the above-mentioned connecting wire. Soldering 34 is applied to a portion where the end portion 33 and the exciter feeding end 22b face each other. In the above tentative plan (FIG. 6), after soldering, there is a serious problem that even if one wants to readjust, it cannot be easily performed. That is, when the mobile phone in use becomes sick for some reason and the high frequency unit is disconnected from the antenna circuit to connect to the tester, the soldering portion 34 is heated to melt and become liquid. In addition, since it is necessary to suck and remove the solder, a great deal of trouble is required, and there is a risk that the high-frequency unit of high integration will be affected by the heat of the solder melting operation. Further, if the end portion 33 of the connecting wire is made to project from the measuring connector 32, the measurement by the tester is affected and a measurement error increases, which is a serious problem. Also, after the inspection and adjustment by the tester is finished at the production factory, the soldering 3
There is also a technical difficulty in the operation of applying No. 3, and it requires a high degree of skill to solder in a narrow space without affecting the electronic components in the vicinity, and it requires manual work. This hinders the automation of the manufacturing process and causes an increase in manufacturing cost. FIG. 7 is an explanatory view schematically showing a different tentative plan from the above for connecting a high frequency unit of an antenna device according to an unknown prior application. Feeder end 22b of the exciter
Is connected to one end of the coaxial cable 36, and an antenna connection plug 35 is connected to the other end of the coaxial cable 36. After a plug (not shown) connected to a tester (not shown) is inserted into the measurement connector 32 for inspection and adjustment, the plug is removed and the antenna connection plug 35 is attached to the measurement connector 32. Then, the measuring connector 32 functions as an antenna connecting connector as it is. According to this tentative plan (Fig. 7),
The coaxial cable 36 and the antenna connection plug 35 are required, the number of constituent parts is large, and the manufacturing cost is increased. In addition, the operation of inserting and removing the plug into and from the connector provided in the narrow space inside the portable telephone requires a high degree of skill, which hinders automation, resulting in an increase in manufacturing cost.

The present invention has been made in view of the above-mentioned circumstances, and it can be constructed in a small size, a light weight, and a low cost, has a small number of constituent parts, and further, inspects and adjusts the high frequency unit of the radio main body. It is an object of the present invention to provide a technique for easily and quickly connecting the high frequency unit to the antenna circuit after the inspection and adjustment are completed. The connection between the antenna and the high frequency unit, to which the present invention is applied, needs to be particularly considered so as not to cause excessive quality. That is, a large number of mobile telephones are produced and inspected and adjusted once per macro device (re-inspection and re-adjustment are also possible,
Since it is a close process, it can be regarded as one process from a macro perspective.) After shipping and use,
The proportion of items brought to the service factory and readjusted is not so large. Therefore, from the perspective of one machine, it is expected that the number of times of switching and connection to the tester is about several times between the time of production and the time of disposal. Considering these usage conditions, it is not required to endure tens of thousands of uses like general household electric appliances, but instead, it is required to be small, lightweight and inexpensive. Therefore, the present invention has been made in pursuit of an extremely simple configuration, on the condition that it is sufficient to withstand several temporary uses. The simple structure facilitates miniaturization.
In the embodiment of the present invention, the outer dimensions of the connector socket are set to 4 × 4 × 2.5 (unit: mm) in the embodiment described later, and reliable operation is confirmed.

[0009]

As described above, the present invention is an improvement of the invention according to the previously unknown prior application, and its inspection,
The adjustment is made easy. Therefore, the structure that is an essential requirement of the present invention is closely related to the previously unknown invention of the prior art, and has a technical significance on the basis of this relationship.

According to the method of the present invention, the antenna circuit for a mobile communication device and the output terminal of the high frequency unit of the mobile communication device main body are connected via a connector socket having a switch function, and the tester of the high frequency unit is connected. By inserting the connected connector plug into the connector socket, the conduction between the high frequency unit and the antenna circuit is cut off, and the high frequency unit is conducted to the tester.
By removing the connector plug from the connector socket, the high-frequency unit and the tester are disconnected from each other, and the high-frequency unit is connected to the antenna circuit. The antenna circuit in the method of the invention is opposed to an antenna element whose both ends are open and resonates at approximately λ / 2 in a non-conducting state with respect to the antenna element through a coupling capacitance, and has approximately λ / It is recommended that the connector socket having the switching function is interposed between the power supply end of the exciter and the output end of the high frequency unit. Together with the above method, the ground plane of the antenna circuit and the ground plane of the high-frequency unit output circuit are shared so as to maintain a continuous conductive state with each other, and the transmission line on the antenna circuit side is connected to the switch built in the connector socket. While connecting to the fixed contact, the transmission line on the high frequency unit output circuit side is connected to the movable contact piece of the switch, and the earth side terminal of the connector plug connected to the tester circuit is brought into contact with and electrically connected to the main plate. The movable contact piece of the switch is pushed by the transmission line side terminal of the connector plug to switch the conduction of the movable contact piece from the fixed contact to the connector plug transmission line terminal, and the measurement and adjustment of the high frequency unit by the tester circuit is performed. After that, the connector plug is detached from the connector socket, and the elastic contact force of the movable contact piece causes the movable contact piece to move. Contacting the fixed contacts, allowed to conduct, the effect of the present invention method is more sufficiently exhibited.

The device of the present invention comprises a jack-type connector socket having a switch function, and (a) a sleeve made of an electrically insulating material having a central hole having a rectangular cross section; (C) a fixed contact arranged in the immediate vicinity of the wall corresponding to the short side of the rectangle, and (c) a movable contact arranged so as to face the fixed contact and contact and conduct with the fixed contact without receiving an operating force. And a piece. In the present invention, the jack is a device for making an electrical connection by inserting a plug, and is used by fixing one base and one or more contact spring pieces insulated with an insulating piece and fixing them to a device. It refers to the connector.

[0012]

According to the above means, since the antenna and the high-frequency unit output end are connected through the normally closed switch built in the connector socket having an extremely simple structure, a different operation force is applied. Not yet
A high frequency circuit of a mobile wireless device such as a mobile phone is constantly conducted to a power supply end of an antenna circuit. Since it is a normally-closed type switch, OF
F will be done. When the switch is turned off, the antenna circuit is electrically disconnected from the high frequency unit circuit. Since the member for applying the above operating force is the connector plug and is connected to the tester, the high frequency unit circuit is switched to the tester at the same time as the above OFF operation.
In this state, since it is not necessary to project the end of the connecting wire for soldering, the end of the connecting wire does not affect the measurement by the tester, and accurate adjustment is possible. Further, when the connector plug is removed from the connector socket, the normally closed switch mechanism is automatically turned on by the elastic restoring force of the leaf spring, the high frequency unit circuit is connected to the antenna circuit, and this connection state is constantly maintained. It In addition, since the movable contact piece forming the normally closed switch is U-shaped or V-shaped and is installed in the central hole having a rectangular cross section, the size required in a relatively small central hole is required. The movable contact piece can be housed, and the device can be downsized while being compatible with the operation reliability.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to FIGS.
An example of the present invention will be described. FIG. 1 shows an embodiment of a connection device between a high frequency unit and an antenna according to the present invention,
(A) is an external plan view, (B) is a sectional side view showing a B-B section, and (C) is a sectional front view also showing a C-C section. 1 is a connector with a switch function, and FIG. 2 is a partial cross-sectional view schematically illustrating a mobile communication device including the connector with a switch function of the embodiment shown in FIG. The above-mentioned FIG. 2 is based on the above-mentioned tentative plan.
FIG. 9 is a diagram corresponding to the above, and is an example improved by applying the present invention to the connection device according to the tentative plan. In FIG. 2, the same reference numerals as those in FIGS. 6 and 7 described above denote the same or similar components as those in the above-mentioned trial. This example (Fig. 2)
In FIG. 1, the power feeding end 22b of the λ / 4 exciter 22 is connected to the output end 30 of the radio frequency unit 31 by the switch function connector socket (abbreviation: switch function connector) 1. The microstrip line 24 shown in FIG. 2 is the constituent part described above with reference to FIG. 4 (the invention of the prior application), and the microstrip line 24 is formed on one surface of the substrate 27 on the surface opposite to the ground plane 23. It is a conduction pattern of the formed transmission line, and has a simple structure and functions similar to a coaxial cable. Details of the configuration of the connector 1 with a switch function will be described below with reference to FIG. On the substrate 27, a short tubular insulator sleeve 1a made of an electrically insulating material is installed. In the section of (B),
A cross section of the base plate 23 laminated on one surface of the substrate 27 is shown. Further, FIGS. 2A and 2C show the exciter feed end 22b and the microstrip line 24 described above (FIG. 2). A metal earth cylinder 1b is externally fitted and fixed to the insulator sleeve 1a. A cylinder earth terminal 1c is formed on the earth cylinder 1b and is soldered to the base plate 23 as shown in FIG. This soldering serves two functions of ensuring continuity and fixing the connector with a switch function. The central hole of the insulator sleeve 1a is a square hole 1d. In this example, the central hole (square hole 1d) is a bottomless hole, but it can be a bottomed hole. As shown in (A), the square hole 1d of this example has a rectangular cross-sectional shape in which the left and right sides of the figure are short sides and the upper and lower sides are long sides, and corresponds to the short sides. The fixed contact 1f is arranged in contact with the wall surface, and the exciter feeding end 22
Soldered to b. The movable contact piece 1g is composed of a U-shaped or V-shaped leaf spring, and is in close contact with and electrically connected to the fixed contact 1f when no external force is applied as shown in FIG. It forms a normally closed switch. In this way, if the width direction of the leaf spring-shaped movable contact piece 1g is aligned with the short side direction of the rectangular rectangular hole 1d and the movable contact piece 1g is arranged so that it can be contacted and disconnected in the rectangular hole 1d, the size of the rectangular hole is increased. The movable contact piece and the fixed contact, which are larger than the above, can be accommodated in the square hole. As a result, the shape and size of the connector socket can be made small, and reliable contact conduction can be obtained. FIG. 3 is a cross-sectional view showing a state in which a connector plug for connecting a tester is inserted in the connector with a switch function shown in FIG. 1 and cut in the same plane as in FIG. 1C and viewed in the same direction. is there. The tester connecting connector plug of this example has a rectangular square hole 1d which is the central hole of the insulator sleeve 1a shown in FIG.
A center contact pin 2a having a diameter that fits the short side of the connector, a connector sleeve 2b that closely fits the earth cylinder 1b, and an insulating sleeve 2c that holds both members substantially concentrically. ing. When the connector sleeve 2b is externally fitted to the earth cylinder 1b, they are brought into contact with each other and together with the center contact pin 2a.
Is inserted into the rectangular hole 1d, the center contact pin 2a contacts the movable contact piece 1g to conduct electricity, and separates the movable contact piece 1g from the fixed contact 1f. By the above-mentioned action, the microstrip line 24 which is conducted to the output end of the high frequency unit is cut off from the exciter feeding end 22b and is connected to the tester connecting connector plug 2 (not shown). ) Is switched on. Figure 3
When the tester connecting connector plug 2 is pulled out from the state shown in Fig. 2, the conduction between the high frequency unit and the tester is cut off, and the movable contact piece 1g comes into contact with the fixed contact by the elastic restoring force and conducts (Fig. 1 (see (C)).
In this state, the high frequency unit 31 (see FIG. 2) of the mobile phone is electrically connected to the power supply end 22b of the exciter 22 via the microstrip line 24 and the connector socket 1 with a switch function. Since the exciter 22 is electromagnetically coupled to the λ / 2 antenna element 21 via the coupling capacitance, the antenna element 21 performs a radio wave transmission / reception function in a non-contact state.

As shown in FIG. 2, the portable telephone to which the present invention is applied has a connector socket 1 with a switch function.
Is used in a state of being stored in the housing 26 of the mobile phone. Therefore, when a failure occurs in the mobile phone in use and it is necessary to measure the electrical performance of the high frequency unit 31 of the radio main body, the lid (not shown) of the housing 26 is opened and the tester is opened. The connection connector plug 2 (FIG. 3) can be inserted into the connector socket 1 with a switch function to perform measurement and required adjustment. When the measurement / adjustment is completed and the tester connection connector plug 2 is pulled out, the high frequency unit is Restores the state of being connected to the antenna circuit.

It is desired that the connector installed in the portable telephone for connecting the tester be small and lightweight. The maximum allowable size varies depending on the usage conditions, etc., so it cannot be said unequivocally, but since the density and integration of electronic components are increasing in recent years, the connector socket height is 2.5 Limited to millimeters. Since the connector socket with a switch function of the present embodiment has the simple structure as described above, it can be easily constructed in a small size.
Although the actual size of this embodiment is set to 2.5 mm in height and 4 mm × 4 mm in installation area, there is no particular difficulty in parts production and assembly work, and the required mechanical performance and electrical performance can be satisfied. It was As described above, sufficient performance can be obtained even if the structure is made small, but it is an overall result of the constitutional requirements of the present invention.
It is considered that the rectangular hole 1d serving as the central hole of a contributes greatly. The reason is as follows.
The center hole of the conventional socket-type connector has a circular cross section. When trying to store a rectangular leaf spring (movable contact piece) in this circle, the maximum rectangle that can be stored is the inscribed rectangle of the circle, and the area of the inscribed rectangle with respect to the cross-sectional area of the circular hole is 2 /Π=0.637 cannot be exceeded. Moreover, the inner wall surface of the circular hole does not perform the positioning or guiding function of the fixed contact or the movable contact piece. On the other hand, in this embodiment (see FIGS. 1A and 1C), the fixed contact 1f is positioned and supported by the wall surface corresponding to the short side of the rectangular hole 1d having a rectangular sectional shape. The movable contact piece 1g is positioned and guided by the wall surface corresponding to the long side of the square hole 1d. Moreover, FIG. 1 is a plan view.
As shown in (C), the fixed contact 1f and the movable contact piece 1g occupy a projected area of approximately 100% of the sectional area of the square hole 1d. Such high-density arrangement and support / guide effects were obtained because (a) the central hole of the insulator sleeve 1a was a rectangular square hole 1d, and (b) the fixed contact 1f and the movable contact piece. This is because the width dimension of 1 g is configured to fit with the two-side width dimension corresponding to the short side of the square hole 1d.

[0016]

When the present invention is applied, since the antenna and the high-frequency unit output end are connected through the normally closed switch built in the connector socket having an extremely simple structure, a different operating force is required. The high frequency circuit of a mobile radio such as a mobile phone is
The power supply end of the antenna circuit is constantly conducted. Since it is a normally closed switch, it is turned off by applying an operating force. When the switch is turned off, the antenna circuit is electrically disconnected from the high frequency unit circuit. Since the member for applying the above operation force is the connector plug and is connected to the tester, the above OFF
Simultaneously with the operation, the high frequency unit circuit is switched to the tester and is conducted. In this state, it is not necessary to project the connection wire end for soldering, so that the connection wire end does not affect the measurement by the tester, and accurate adjustment is possible. Further, when the connector plug is removed from the connector socket, the normally closed switch mechanism is automatically turned on by the elastic restoring force of the leaf spring, the high frequency unit circuit is connected to the antenna circuit, and this connection state is constantly maintained. It In addition, since the movable contact piece forming the normally closed switch is U-shaped or V-shaped and is installed in the central hole having a rectangular cross section, the size required in a relatively small central hole is required. The movable contact piece can be housed, and it has an excellent practical effect that the apparatus can be downsized while being compatible with the operation reliability.
