Japanese Patent Laid-Open No. 10-3968 JP 2004-281179 A

However, in the coaxial connector with a switch shown in Patent Document 1, the fixed terminal and the movable terminal are formed of a metal plate. Further, in the coaxial connector with a switch shown in Patent Document 1, the above assembly process is required as shown in FIG. These require the pressing of a flat metal material using a press die, or the coaxial connector 1 with a switch by inserting a metal plate (movable terminal) 5 and a metal plate (fixed terminal) 4 in order. Therefore, the manufacturing cost is increased and the manufacturing process is complicated.

Further, in the above assembly process, the synthetic resin insulating case 2 may be scraped off when the metal plate 4 and the metal plate 5 are inserted, and the scraped resin adheres to the contact portion between the metal plate 4 and the metal plate 5. There was also. For this reason, the coaxial connector with a switch disclosed in Patent Document 1 sometimes causes a contact failure at the same contact portion.

Also, in the coaxial connector with a switch shown in Patent Document 2, a similar assembly process is required, and the same problem occurs because the fixed terminal and the movable terminal are formed of a metal plate.

An object of the present invention is to provide a coaxial connector with a switch having good contact reliability between a fixed terminal and a movable terminal, reducing the manufacturing cost and reducing the manufacturing process, a method for manufacturing the coaxial connector with the switch, and the coaxial with the switch An object of the present invention is to provide a communication device provided with a connector.

The coaxial connector with a switch according to the present invention has the following configuration in order to solve the above problems.
(1) an insulating case provided with an insertion port into which the center contact of the inspection probe is inserted;
An insulating substrate that forms an internal space communicating with the insertion port together with the insulating case;
An elastic body formed on the insulating substrate in the internal space such that the surface on the insertion port side contacts the inner surface of the insulating case when the center contact is not inserted;
An electrode film formed on at least the insertion port side surface of the elastic body;
A first electrode formed on the inner surface of the insulating case so as to contact the electrode film of the elastic body when the center contact is not inserted;
A second electrode formed on at least one of the elastic body, the insulating case and the insulating substrate so as to be connected to the electrode film of the elastic body and not to be connected to the first electrode;
An external terminal formed on at least a part of the outer wall of the insulating case.

In this configuration, the elastic body connects the electrode film and the first electrode by the elastic force (restoring force) when the center contact is not inserted. Thereby, the state which the 2nd electrode electrically connected with the 1st electrode via the electrode film is obtained. Here, the second electrode, the electrode film, and the first electrode are mainly formed of a metal film.
On the other hand, when the center contact is inserted, the elastic body is contracted and deformed by the pressing of the center contact to dissociate the electrode film and the first electrode. Thereby, the state which the 2nd electrode conducted with the center contact via the electrode film is obtained. As a result, the signal path from the second electrode to the first electrode is switched to the signal path from the second electrode to the center contact.

As described above, according to the coaxial connector with a switch in this configuration, since the contact is switched only by the elasticity of the elastic body without using the metal plate, the manufacturing cost of the press mold for forming the metal plate can be reduced.
In addition, the coaxial connector with a switch in this configuration can be manufactured simply by forming an elastic body or the like on the insulating substrate, so that the manufacturing process can be streamlined.
Therefore, according to this configuration, it is possible to manufacture a coaxial connector with a switch that can reduce the manufacturing cost and reduce the manufacturing process.

(2) The second electrode of (1) above is
A plate-like electrode formed on the surface on the insertion port side of the insulating substrate and a mounting surface facing the surface on the insertion port side;
An electrode formed in a via hole that conducts both plate-like electrodes formed on the surface on the insertion port side of the insulating substrate and the mounting surface;
A second electrode film that conducts between the electrode film formed on the elastic body and the flat electrode formed on the surface of the insulating substrate on the insertion opening side.

In this configuration, the specific first wiring pattern of the second electrode of (1) is clearly shown.

(3) The insulating substrate of (1) includes a through hole into which the insulating case is inserted,
The second electrode of (1) above is
A flat electrode formed on the surface of the insulating substrate on the insertion port side;

A third electrode,
A second electrode film that conducts the electrode film formed on the elastic body and the flat electrode.

In this configuration, the specific second wiring pattern of the second electrode of (1) above is clearly shown.

(4) The insulating substrate of (1) includes a through hole into which the insulating case is inserted,

In the configuration (4), when the position of the center contact is not decentered, it is not always possible to perform signal switching reliably. Accordingly, it is desirable that the center of the elastic body to be molded viewed from the insertion port side of the elastic body is shifted from the center of the insertion port to the second electrode side.
Thereby, even when the center contact is made to enter the center of the insertion opening when the probe is mounted, a state is obtained in which the electrode film is connected to the second electrode and dissociated from the first electrode. That is, signal switching can be reliably performed even if an inspection probe having a center contact is inserted into the insertion port as usual.

(6) It is desirable that a rigid layer be formed between the elastic body according to any one of (1) to (5) and the electrode film.

In this configuration, when the inspection probe is attached to the coaxial connector with a switch and the elastic body is pressed downward by the tip of the center contact, the entire elastic body is contracted and deformed. Therefore, when the inspection probe is mounted on the coaxial connector with a switch, the entire elastic body contracts and deforms even when the contact position of the tip of the center contact with the electrode film of the elastic body deviates from the center of the upper surface of the elastic body. The electrode film and the first electrode are surely dissociated.
Therefore, the insulation between the electrode film and the first electrode when the inspection probe is attached to the coaxial connector with a switch can be enhanced.

Also, the communication device of the present invention has the following configuration in order to solve the above problems.

(7) A coaxial connector with a switch according to any one of (1) to (6) above is provided.

<< First Embodiment >>
The configuration of the coaxial connector with a switch according to the first embodiment will be described with reference to FIGS.
FIG. 3 is a perspective view of the coaxial connector with a switch according to the first embodiment of the present invention. FIG. 4 is a cross-sectional view of the coaxial connector with a switch according to the first embodiment of the present invention, and FIG. 5 is a cross-sectional view when the probe of the coaxial connector with a switch according to the first embodiment of the present invention is mounted. is there.

A coaxial connector with a switch (hereinafter simply referred to as a connector) 101 includes an insulating case 102, an insulating substrate 108, an elastic body 106, a movable metal film 161, a movable metal film 141, a movable-side mounting electrode 104, and a fixed A side electrode 151, a fixed-side mounting electrode 105, and an external terminal (ground terminal) 110 that covers the main part of the insulating case 102 are provided. In this embodiment, the movable side mounting electrode 104, the movable metal film 161, and the movable metal film 141 constitute a movable terminal, and the fixed side mounting electrode 105 and the fixed side electrode 151 constitute a fixed terminal. The movable-side mounting electrode 104 and the movable metal film 141 are not directly connected to the fixed-side mounting electrode 105 and the fixed-side electrode 151 but are connected via the movable metal film 161.
Here, the fixed-side mounting electrode 105 and the fixed-side electrode 151 correspond to the “first electrode” of the present invention. The movable-side mounting electrode 104 and the movable metal film 141 correspond to the “second electrode” of the present invention. The movable metal film 161 corresponds to the “electrode film” of the present invention.

On the insulating substrate 108, a movable side mounting electrode 104 and a fixed side mounting electrode 105 are formed, for example, alumina or synthetic resin. The insulating case 102 is disposed or formed on the upper surface of the insulating substrate 108, and is formed of alumina, synthetic resin, or the like, for example.

The movable mounting electrode 104 includes a flat plate electrode formed on the surface on the insertion port 107 side of the insulating substrate 108 and a mounting surface facing the surface on the insertion port 107 side, and on the insertion port 107 side of the insulating substrate 108. And an electrode formed in a via hole for conducting both plate-like electrodes formed on the surface and the mounting surface.

The fixed-side electrode 151 extends from the contact portion in contact with the movable metal film 161 to the inner surface of the insulating case 102B facing the elastic body 106 from the upper surface of the insulating substrate 108 where the fixed-side mounting electrode 105 is formed. It is formed to stretch. That is, the end of the fixed side electrode 151 is connected to the fixed side mounting electrode 105.

The elastic body 106 has a trapezoidal cross section on the upper surface of the insulating substrate 108. As a material of the elastic body 106, JCR6126 manufactured by Toray Dow Corning was used. Of course, the present invention is not limited to this, and other epoxy resins and silicone resins may be used. In the elastic body 106, a movable metal film 161 is formed on the upper surface of the elastic body 106, and the movable metal film 161 formed on the upper surface of the elastic body 106 is connected to the movable-side mounting electrode 104 formed on the insulating substrate 108. A movable metal film 141 is formed on the movable slope of the elastic body 106. That is, the movable metal film 161 and the movable metal film 141 are formed so as to extend the surface of the elastic body 106 from a contact portion that contacts the fixed side electrode 151 to a point that contacts the movable side mounting electrode 104. That is, the end of the movable metal film 141 is connected to the movable side mounting electrode 104.

The movable metal film 161 is configured to come into contact with the lower surface of the fixed-side electrode 151 by the urging force (elastic force) of the elastic body 106 so that the movable metal film 161 and the fixed-side electrode 151 come into contact with each other. .

On the opposite side of the insulating case 102 from the insulating substrate 108, an insertion port 107 opened in a mortar shape is formed. In addition, the insulating case 102 is a standing columnar internal space and is formed with a recess 116 that communicates with the insertion port 107 together with the insulating substrate 108. For example, when a set manufacturer checks the electrical characteristics of a high-frequency circuit of a communication device such as a mobile phone, the center contact 21 of the inspection probe 20 enters the insulating substrate 108 side from the mortar-shaped insertion port 107. . When the tip of the center contact 21 abuts on the movable metal film 161 of the elastic body 106 and presses the elastic body 106 downward, the elastic body 106 contracts and deforms, and the movable metal film 161 and the fixed side electrode 151 are dissociated. (See FIG. 5). As a result, the signal path from the movable side mounting electrode 104 to the fixed side mounting electrode 105 is switched to the signal path from the movable side mounting electrode 104 to the center contact 21.

Next, a manufacturing method of the coaxial connector with a switch according to the first embodiment will be described with reference to FIGS. 6 to 8 in this order.

6 is a cross-sectional view of an insulating substrate on which a movable-side mounting electrode and a fixed-side mounting electrode are formed. FIG. 7 is a cross-sectional view of an insulating substrate on which an elastic body having a metal film is formed. FIG. 8 is a cross-sectional view of an insulating substrate on which an insulating case having a metal film is formed. The manufacturing method of the connector 101 includes a case forming step for forming the insulating case 102 and a first electrode forming step for forming the first electrodes (the fixed-side mounting electrode 105 and the fixed-side electrode 151 in this embodiment) on the insulating case 102. A substrate forming step for forming the flat insulating substrate 108, an elastic body forming step for forming the elastic body 106 on the insulating substrate 108, and a movable metal film 161 formed on the surface of the elastic body 106 that contacts the insulating case 102. An electrode film forming step, a second electrode forming step for forming a second electrode (movable side mounting electrode 104 and movable metal film 141 in this embodiment), an assembly step for assembling the insulating case 102 and the insulating substrate 108, And an external terminal forming step of forming the external terminal 110 on at least a part of the outer wall of the insulating case 102.

First, the insulating substrate 108 in which the through hole for the movable side mounting electrode 104 and the through hole for the fixed side mounting electrode 105 are formed is injection-molded using a mold. Then, a conductor is formed by screen printing, for example, Ag paste on both ends of the upper surface of the insulating substrate 108, both ends of the lower surface of the insulating substrate 108, and the insides of both through holes. Thus, the insulating substrate 108 on which the movable side mounting electrode 104 and the fixed side mounting electrode 105 made of, for example, an Ag film are formed is completed (see FIG. 6).
In order to prevent oxidation, the surface of the Ag film may be plated.

Further, the insulating substrate 108 may be formed by drilling a synthetic resin substrate with a laser, the electrode formed in the through hole portion may be Au, Ni, Cu, Ti, or the like, and the formation method may be plating.

Next, the elastic body 106 is formed by, for example, screen printing JCR6126 made by Toray Dow Corning on the upper surface of the insulating substrate 108 of FIG. Then, an Au / Ti film is formed on the surface of the elastic body 106, for example, a metal mask so as to extend from the contact portion in contact with the fixed-side electrode 151 to the portion on the upper surface of the insulating substrate 108 where the movable-side mounting electrode 104 is formed. It is formed by vapor deposition. As a result, the movable metal film 161 and the movable metal film 141 are integrally formed on the upper surface and the movable slope of the elastic body 106 (see FIG. 7). Of course, the elastic body 106 may use other epoxy-based or silicone-based products. At this time, it is desirable to form so that the Young's modulus is about 10 to 500 MPa.

Next, the insulating case 102 in which the mortar-shaped insertion port 107 and the recess 116 for accommodating the elastic body 106 are formed is injection-molded using a mold. The outer periphery of the recess 116 is formed to be larger than the outer periphery of the elastic body 106, and the depth of the recess 116 is formed smaller than or equal to the thickness of the elastic body 106. Thereby, the height of the elastic body 106 is higher than or equal to the height of the internal space formed by the recess 116 and the insulating substrate 108. Further, the insertion port 107 has a shape smaller than the outer periphery of the elastic body 106. Subsequently, the fixed-side electrode 151 is formed on the surface on the recess 116 side of 102 </ b> B, which is a partial region of the insulating case 102 facing the elastic body 106. The fixed-side electrode 151 includes an inner surface of the insulating case 102B facing the elastic body 106 from a contact portion that contacts the movable metal film 161 to a portion where the fixed-side mounting electrode 105 is formed on the upper surface of the insulating substrate 108. For example, Au / Ti is formed by vapor deposition of a metal mask so as to be stretched. Then, the insulating case 102 having the fixed-side electrode 151 is pressure-bonded to the upper surface of the insulating substrate 108 so that the outer periphery of the elastic body 106 is accommodated in the recess 116 (see FIG. 8). At this time, when the height of the elastic body 106 is higher than the height of the internal space formed by the concave portion 116 and the insulating substrate 108, the elastic resin 106 is accommodated in the concave portion 106 in a contracted state. As a result, the movable metal film 161 is brought into contact with the lower surface of the fixed electrode 151 by the urging force (elastic force) of the elastic body 106, so that the movable metal film 161 and the fixed electrode 151 are reliably in contact with each other.
As shown in FIG. 9, a fixed-side electrode 152 having a surface parallel to the surface of the insulating substrate 108 is formed only on the inner surface on the 102B side of the insulating case 102 facing the upper surface of the insulating substrate 108. The fixed side electrode 152 and the fixed side mounting electrode 105 may be connected by a conductor formed in the through hole. In this structure, after the insulating substrate 109 is formed or pressure-bonded on the upper surface of the insulating substrate 108 in FIG. Created with.

Finally, a thin metal plate is formed into a cylindrical shape by drawing or the like, and the external terminal 110 is attached to the outer surface side of the insulating case 102 so as to sandwich the insulating case 102. Thereby, the connector 101 is completed (see FIG. 4).

As described above, in the conventional connector, it is necessary to form the fixed terminal and the movable terminal with a metal plate. According to the connector 101 in this embodiment, the fixed terminal including the fixed side electrode 151 and the fixed side mounting electrode 105 The movable metal film 141, the movable metal film 161, and the movable terminal including the movable side mounting electrode 104 are formed of a metal film. Therefore, the manufacturing cost of the press mold can be reduced.
Further, in the conventional connector, an assembly process for assembling the connector by sequentially inserting the movable terminal and the fixed terminal is required. According to the connector 101 in this embodiment, the elastic body 106 and the like are provided on the insulating substrate 108. It only forms. Therefore, it is possible to reduce the manufacturing process.

Furthermore, in the connector proposed in Patent Document 1, in the assembly process described above, the synthetic resin insulating case may be scraped off when the movable terminal and the fixed terminal are inserted. Since no process is required, the synthetic resin insulating case is not scraped off when the movable terminal and the fixed terminal are inserted. Therefore, the resin does not adhere to the contact portion between the movable metal film 161 and the fixed side electrode 151. Therefore, in the connector 101 in this embodiment, contact failure does not occur at the same contact portion.

Therefore, according to this embodiment, it is possible to manufacture the connector 101 with good contact reliability between the fixed terminal and the movable terminal while reducing the manufacturing cost and slimming the manufacturing process.

As shown in FIG. 7, a rigid layer 162 may be formed between the movable metal film 161 and the elastic body 106. In this case, when the inspection probe 20 is attached to the connector 101 and the elastic body 106 is pressed downward by the tip of the center contact 21, the entire elastic body 106 is contracted and deformed. Therefore, when the inspection probe 20 is attached to the connector 101, even when the contact position of the tip of the center contact 21 with respect to the movable metal film 161 of the elastic body 106 is deviated from the center of the upper surface of the elastic body 106, the entire elastic body 106. Therefore, the movable metal film 161 and the fixed electrode 151 are surely dissociated. Therefore, the insulation between the movable metal film 161 and the fixed-side electrode 151 when the inspection probe 20 is attached to the connector 101 can be improved. The rigid layer 162 is preferably made of a material having a Young's modulus of 2 GPa or more.

Hereinafter, the manufacturing method of the connector 201 will be described separately for the case seen from the SS line in FIG. 10 and the case seen from the TT line in FIG. First, a process of manufacturing the connector 201 when viewed from the SS line in FIG. 10 will be described.

First, as shown in FIG. 11 (A), an insulating substrate 208 in which a through hole 211 for inserting the insulating case 202 shown in FIG. 11 (B) is formed is injection-molded with a mold. Then, the elastic body 106 is formed on the upper surface of the insulating substrate 208. As with the connector 101 according to the first embodiment, the movable metal film 161 and the movable metal film 141 are formed on the upper surface and the movable slope of the elastic body 106. Further, the movable side electrode 171 to be connected to the movable side mounting electrode 204 is formed on the upper surface of the insulating substrate 208 by vapor deposition of, for example, Au / Ti. Thereby, a movable side member is completed.
The material of the insulating substrate 208 is the same as that of the insulating substrate 108 of the connector 101 according to the first embodiment. Further, similarly to the connector 101 according to the first embodiment, a rigid layer 162 may be formed between the movable metal film 161 and the elastic body 106.

Next, as shown in FIG. 11B, an insulating case 202 injection-molded with a mold is provided with a movable-side mounting electrode 204 and a fixed-side mounting electrode 205 as a fixed-side member. The materials and production methods of the insulating case 202, the movable side mounting electrode 204, and the fixed side mounting electrode 205 are the same as those shown in the first embodiment. The external terminals 110 are formed on the outer periphery of the insulating case 202 by, for example, metal mask vapor deposition.

Finally, the insulating case 202 is fitted into the through hole 211 of the insulating substrate 208. Thereby, the movable-side mounting electrode 204 is connected to the movable-side electrode 171, and the movable metal film 161 comes into contact with the lower surface of the fixed-side mounting electrode 205 by the urging force (elastic force) of the elastic body 106. A state in which the film 161 and the fixed-side mounting electrode 205 are in reliable contact is obtained. That is, as shown in FIG. 12A, a large number of connectors 201 connected by the connecting portion 213 are completed.

Subsequently, a process of manufacturing the connector 201 when viewed from the TT line in FIG. 10 will be described.

First, as shown in FIG. 13A, an insulating substrate 208 in which a through hole 211 for inserting the insulating case 202 shown in FIG. 13B is formed is injection-molded with a mold. Then, the elastic body 106 is formed on the upper surface of the insulating substrate 208. Then, when the movable metal film 161 is formed on the elastic body 106, the movable member shown in FIG. 13A is completed.

Next, as shown in FIG. 13B, external terminals 210 are formed on the insulating case 202 injection-molded with a mold, for example, by metal mask vapor deposition.

Then, the insulating case 202 is fitted into the through hole 211 of the insulating substrate 208.

Therefore, mechanical strength increases compared with the first embodiment formed by pressure bonding. Further, since the number of parts when assembling is small, the manufacturing cost can be reduced.

<< Third Embodiment >>
A coaxial connector with a switch according to a third embodiment will be described with reference to FIGS. 15 and 16.

15 is a cross-sectional view of a coaxial connector with a switch according to a third embodiment of the present invention, and FIG. 16 is a cross-sectional view of the coaxial connector with a switch according to a third embodiment of the present invention when the probe is mounted. is there. The manufacturing method of the connector 301 according to the third embodiment includes a case forming step of forming the insulating case 202, a first electrode (fixed-side mounting electrode 205 in this embodiment) and a second electrode (this In the embodiment, an electrode forming step for forming the movable side mounting electrode 304), a substrate forming step for forming the flat insulating substrate 208, an elastic body forming step for forming the elastic body 106 on the insulating substrate 208, and an elasticity An electrode film forming step of forming a movable metal film 161 on a surface of the body 106 that contacts the insulating case 202, an external terminal forming step of forming the external terminal 110 on at least a part of the outer wall of the insulating case 202, and the insulating case 202. There are an assembling step for fitting the insulating substrate 208 and a dividing step for dividing the large number of connectors 301 into individual connectors 301. That is, the manufacturing method of the connector 301 according to the third embodiment is the same as the manufacturing method of the connector 201 according to the second embodiment. However, the structure of the connector 301 according to the third embodiment is different from the structure of the connector 101 according to the first embodiment and the connector 201 according to the second embodiment.
The fixed-side mounting electrode 205 corresponds to the “first electrode” of the present invention. The movable-side mounting electrode 304 corresponds to the “second electrode” of the present invention. Furthermore, the movable metal film 161 corresponds to the “electrode film” of the present invention.

In the connector 301 in this embodiment, the fixed-side mounting electrode 205 and the movable-side mounting electrode 304 are formed in the opposing

regions

202A and 202B of the insulating case 202, and the movable metal film 161 is formed only on the upper surface of the elastic body 106. Forming. That is, unlike the

connectors

101 and 201, no metal film is formed on the movable side slope of the elastic body 106.

Therefore, when the inspection probe 20 is attached to the connector 301, even if the elastic body 106 is contracted and deformed by pressing by the center contact 21, no stress is applied to the metal film on the side surface of the elastic body 106 and there is no possibility of disconnection. Therefore, since disconnection due to mounting of the inspection probe 20 can be prevented, the reliability of the apparatus main body can be improved.

Here, the method for forming the movable-side mounting electrode 304 is the same as that of the movable-side mounting electrode 204 shown in the second embodiment. Further, similarly to the connector 101 according to the first embodiment, a rigid layer 162 may be formed between the movable metal film 161 and the elastic body 106. Other configurations are also the same as those shown in the second embodiment.

In the configuration of FIG. 16, when the position of the center contact 21 is not decentered, it is not always possible to perform signal switching reliably. Therefore, as shown in FIG. 17, the elastic body 106 is preferably formed around the position displaced from the center line of the insertion port 107 toward the movable mounting electrode 304 ′. That is, the center Y of the elastic body 106 viewed from the insertion port 107 side is deviated from the center X of the insertion port 107. Thus, even when the center contact 21 is inserted into the center of the insertion port 107 when the probe is mounted, the movable metal film 161 is connected to the movable side mounting electrode 304 ′ and dissociated from the fixed side mounting electrode 205. Is obtained. That is, even if the probe 20 provided with the center contact 21 is inserted into the insertion port 107 as usual, the signal can be switched reliably.
