Description

  The present invention relates to an electronic device.

Conventionally, various connectors are known as components for connecting between substrates or between electronic devices. Different connectors are used depending on the purpose of use. For example, serial cables for connecting peripheral devices such as modems and printers to personal computers, optical fibers for connecting computers, and boards between electronic devices. FPC (Flexible Printed) used
Various connectors such as connectors for Circuit) are widely used.

  There are various shapes of connectors. For example, an FPC connector inserts an end portion of an FPC extending from one board into a connector constituted by a housing, a contact, and the like, and fixes this to the other board. An example of connecting the two substrates by this is known. In order to increase the holding power of the FPC connector and prevent the housing and contacts from being deformed when the FPC is inserted into the connector, a connector in which the contact is fixed to the housing by a press-fit portion formed in the contact and a locking portion. Is known (for example, see Patent Document 1).

  Deformation and breakage of the housing and contacts reduce the function of the connector, so it should be handled carefully. However, prevention of breakage of not only the connector but also components is recognized as an important issue. Action is taken.

  For example, in a capacitive moisture sensor, which is a sensor capable of detecting the moisture content of a detection object by measuring a capacitance value, in order to prevent cracking of insulating materials and peeling of electrodes constituting the sensor In addition, a sensor having a structure in which at least one of the electrodes of the sensor does not directly touch the detection target is known (for example, see Patent Document 2).

  By the way, televisions using LCD (Liquid Crystal Display) (hereinafter referred to as “liquid crystal televisions”) are widely used. For example, as shown in FIG. 5, the liquid crystal television 100 includes a liquid crystal display 101, a backlight unit 102 provided behind the liquid crystal display 101, and an inner housing 103 that holds these inside, and further includes an inner housing. A main board 104 screwed to 103, a switch board 105 provided below the inner casing 103, an inter-board cable 106 connecting the main board 104 and the switch board 105, and the like are provided inside the decorative casing 107. It is arranged and configured.

  Due to restrictions on the front design of the liquid crystal television 100, the switch substrate 105 is often provided near the center of the front surface of the liquid crystal television 100 in the width direction, and the main substrate 104 and the switch substrate are limited in a limited space inside the decorative housing 107. 105, the female connector 104a provided on the main board 104 is close to the switch board 105 on the main board 104, that is, at the bottom side of the plane of the main board 104, and substantially at the center in the width direction. Provided in the section.

  On the other hand, in order to attach the main board 104 to the inner housing 103 with few screws from the viewpoint of cost and labor, the main board 104 is attached to the inner housing 103 at the minimum attachment points including the four corners of the main board 104. It was Accordingly, the screw is not arranged in the vicinity of the female connector 104a.

In order to easily insert a male connector (not shown) into the female connector 104a in the manufacturing process of the liquid crystal television 100, the female connector 104a is parallel to the plane of the main board 104, which is a so-called top-type connector structure. This connector has a simple insertion surface and is configured such that a load is applied to the main board 104 perpendicularly when a male connector (not shown) is inserted.

  However, in the case of the liquid crystal television 100, when a male connector (not shown) is inserted into the female connector 104a, a screw is not disposed in the vicinity due to a load applied in a direction perpendicular to the plane of the main board 104 at that time. There is a problem that the main board 104 bends around the female connector 104a and may be damaged in some cases.

  This problem cannot be solved by the inventions described in Patent Documents 1 and 2, and an insulating member for preventing bending is provided at a position corresponding to the female connector 104a of the inner housing 103. Although this can be alleviated by placing a finger behind 104a and inserting it, there is a problem that costs and labor are required.

  Accordingly, an object of the present invention is to provide an electronic device in which a connector can be efficiently inserted while effectively preventing damage to the substrate at low cost regardless of the arrangement of the mounting member for attaching the substrate to the holding member. That is.

  In order to solve the above-mentioned problems, the invention according to claim 1 is directed to a board provided with a connector, a holding member for holding the board, and the board for attaching the board to the holding member at a predetermined interval. In the electronic device comprising the mounting member, the insertion surface of the insertion port of the connector is provided substantially orthogonal to the plane of the substrate, the mounting member is provided at a corner of the substrate, An insertion port of the connector is an edge of the board and is provided in the vicinity of a substantially central part of one side of the board, the mounting member is constituted by a screw, and the mounting member and the holding member are It is formed of a metal material, and the substrate is a single-sided substrate.

Therefore, it is possible to insert the connector efficiently while effectively preventing the substrate from being bent or damaged regardless of the arrangement of the mounting member provided on the substrate. it can.

  Further, since the substrate is attached to the holding member at a point with a screw, the substrate is likely to be bent by a load from a direction perpendicular to the plane of the substrate on which the attachment member is not disposed.

Furthermore, in order to suppress an increase in the labor of the mounting work accompanying the grounding process that occurs when the mounting member made of a metal material is attached to the holding member made of a metal material, the number of mounting members is reduced to a minimum. It becomes the structure which is further easy to bend to the load of the perpendicular | vertical direction with respect to this plane.

  In addition, since the substrate is a single-sided substrate in which conductor wiring is provided only on one side, the substrate itself is configured to be thin, and particularly, it is easily bent due to a load in a direction perpendicular to the plane of the substrate.

  The mounting member is provided at the corner of the board, and the connector insertion port is the edge of the plane of the board, and is provided in the vicinity of the substantially central part of one side of the board. Since the mounting member is not disposed around the entrance, the configuration is very easy to bend due to a load in a direction perpendicular to the plane of the substrate.

  Further, since the substrate and the holding member are provided at a predetermined interval, a load in a direction perpendicular to the plane of the substrate is applied only to the substrate, and the structure is further easily bent.

It is possible to insert the connector efficiently while effectively preventing breakage at low cost.

  According to the third aspect of the present invention, since the substrate is attached to the holding member at a point with a screw, the substrate is likely to be bent by a load from a direction perpendicular to the plane of the substrate on which the screw is not disposed.

  Even in such a structure, the insertion surface of the connector insertion port is perpendicular to the plane of the board, so that a cable or a connector can be inserted into the connector without applying a load in a direction perpendicular to the plane of the board. Therefore, the effect of preventing the substrate from being bent or damaged can be particularly preferably exhibited.

  According to the invention described in claim 4, the number of mounting members is necessary to suppress an increase in the labor of mounting work due to the grounding process that occurs when mounting the mounting member made of a metal material to the holding member made of a metal material. It will be limited to the minimum. As a result, the load in the direction perpendicular to the plane of the board is more easily bent. However, since the insertion surface of the connector insertion port is perpendicular to the plane of the board, the load in the direction perpendicular to the plane of the board is obtained. Since a cable, a connector, or the like can be inserted into the connector without imparting any resistance, the effect of preventing the substrate from being bent or damaged can be more suitably exhibited.

  According to the fifth aspect of the present invention, since the substrate is a single-sided substrate in which conductor wiring is provided only on one side, the substrate itself is configured to be thin, particularly for a load in a direction perpendicular to the plane of the substrate. It becomes the structure which is easy to bend. In addition, the mounting member is provided at the corner of the board, and the connector insertion port is provided at the edge of the plane of the board and in the vicinity of the center of one side of the board. Since the mounting member is not disposed around the entrance, the configuration is very easy to bend due to a load in a direction perpendicular to the plane of the substrate.

  In such a structure, since the insertion surface of the connector insertion port is perpendicular to the plane of the board, a cable or the like can be inserted into the connector without applying a load in a direction perpendicular to the plane of the board. The effect of preventing the substrate from being bent or damaged can be exhibited very suitably.
