JP2007018755A - Spacer inserted between base plate and connector mounted on base plate, base plate on which connector is mounted, and connector mounted on base plate - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To make a wire harness easy to insert into and pull out from a connector mounted on a base plate. <P>SOLUTION: When a right angle connector 13 is mounted on the base plate 11 by itself (namely, without using a spacer 12 explained below), insertion direction of the wire harness 15 becomes parallel with a mounting face 11a of the base plate 11. Notwithstanding the above, by inserting the spacer 12 having a prescribed shape between the base plate 11 and the right angle connector 13, the insertion direction of the wire harness 15 against the right angle connector 13 can be changed to a direction (shown by an arrow mark AR11) different from that parallel with or perpendicular to the mounting face 11a. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a technique for facilitating insertion / extraction of a wire harness with respect to a connector mounted on a substrate.

  Conventionally, electronic devices represented by MFP (Multi Function Peripherals) realize a predetermined function by combining a plurality of substrates on which various electronic components are mounted. For example, in an MFP, a main board that performs overall control of the entire apparatus, a scanner board that forms a reading unit that reads a document image and generates image data, and a recording unit that records an image based on the image data on a recording medium are configured. The function of the MFP as a whole is realized by combining a printer board for communication and a communication control board for controlling connection with a communication line such as a general public telephone line network.

  Such a combination of a plurality of substrates is realized by mounting a connector through which a wire harness can be inserted / removed on a substrate and electrically connecting the substrates using the wire harness inserted into the connector. In this case, the connector mounting position is often the end of the board in order to facilitate the handling of the wire harness.

  In addition, board-to-board connectors that connect directly between boards without using a wire harness may be used to combine multiple boards, but right-angle type board-to-board connectors must be mounted at the edge of the board. There is.

  Due to these circumstances, a large number of connectors are often concentrated on the end portion of the substrate. For this reason, in electronic devices with a large number of connectors such as MFPs, it may not be possible to mount all the necessary connectors on the edge of the board, so the connector is mounted near the center away from the edge of the board. There are also cases where you are forced to do so.

  On the other hand, as a connector that can insert and remove the wire harness, a straight connector that can insert and remove the wire harness in a direction perpendicular to the connector mounting surface on the board, and a right angle that can insert and remove the wire harness parallel to the connector mounting surface on the board A connector is used.

  Here, since the right angle connector is designed on the assumption that it is mounted on the end portion of the board, when a connector capable of inserting and removing the wire harness is arranged near the center away from the end portion of the board, it is inevitably necessary. A straight connector must be used.

  Patent Document 1 discloses a technique related to a spacer used together with a connector.

Japanese Utility Model Publication No. 5-55942

  However, when a straight connector is used, physical interference or electromagnetic interference may occur due to the proximity of another wiring board or the like above the mounting surface of the straight connector to the wire harness.

  On the other hand, when a right angle connector is used in order to avoid this problem, other components on the mounting surface of the right angle connector may come close to the wire harness, making it difficult to insert or remove the wire harness.

  The present invention has been made to solve these problems, and it is an object of the present invention to facilitate the insertion and removal of a wire harness with respect to a connector mounted on a board.

  In order to solve the above-mentioned problem, the invention of claim 1 is a spacer that is inserted between a substrate and a connector that is mounted on the substrate and into which a wire harness can be inserted and removed. When inserted in between, the insertion / extraction direction of the wire harness with respect to the connector is changed in an oblique direction different from a direction parallel to and perpendicular to a mounting surface of the connector on the substrate.

  When the spacer according to claim 1 is inserted between the substrate and the connector, the insertion direction of the wire harness with respect to the connector is changed from a direction parallel to the mounting surface. Change in the diagonal direction.

  Invention of Claim 3 is the board | substrate which mounted the connector which can insert / remove a wire harness, Comprising: The insertion / extraction direction of the said wire harness with respect to the said connector is inserted by inserting a spacer between the said board | substrate and the said connector, The board is changed in an oblique direction different from a direction parallel to and perpendicular to the mounting surface of the connector.

  The invention according to claim 4 is a connector mounted on a substrate and capable of inserting and removing a wire harness, and the insertion and removal direction of the wire harness with respect to the connector is parallel to and perpendicular to the mounting surface of the connector on the substrate. It is an oblique direction different from the direction.

  According to the first to fourth aspects of the present invention, since the wire harness can be inserted / removed in an oblique direction with respect to the connector mounted on the substrate, the wire harness can be inserted / removed even when the connector is mounted on a portion other than the end of the substrate. It becomes easy to avoid interference between the wire harness and other members.

<First Embodiment>
FIG. 1 is a side view showing a state in which a right angle connector 13 is mounted on a substrate (electronic circuit printed circuit board) 11 in the first embodiment of the present invention.

  As shown in FIG. 1, various electronic components including the right angle connector 13 are mounted on the mounting surfaces 11 a and 11 b of the substrate 11 by soldering. More specifically, on the substrate 11, the surface mounting type electronic component 14 is placed on the lands formed on the mounting surfaces 11 a and 11 b and soldered, and the lead type right angle connector 13 is mounted. A lead 13L is inserted and soldered into a through hole formed so as to penetrate the mounting surfaces 11a and 11b. Various electronic components mounted on the substrate 11 are electrically connected by wiring patterns formed on the outer layer (mounting surfaces 11a and 11b) and the inner layer of the substrate 11, and constitute an electronic circuit having a predetermined function. ing.

  Such a substrate 11 is a main substrate that performs overall control of the entire MFP (Multi Function Peripherals), for example, a scanner substrate that constitutes a reading unit that reads a document image and generates image data, and an image based on the image data. Electrically by a printer board constituting a recording unit for recording on a recording medium, a communication control board for controlling connection with a communication line such as a general public telephone line network, and a wire harness 15 that can be inserted into and removed from the right angle connector 13 It is connected. FIG. 1 shows an example in which a connector 16 that can be fitted to the right angle connector 13 is attached to the tip of the wire harness 15, but the wire harness 25 that is plated on the tip is directly attached. The adoption of the mode of inserting into the right angle connector 13 is not hindered.

  When the right angle connector 13 is mounted on the substrate 11 alone (that is, without using a spacer 12 described later), as shown in FIG. 3, the insertion / extraction direction of the wire harness 15 is such that the mounting surface 11a of the substrate 11 is mounted. In the first embodiment, a spacer 12 having a predetermined shape is inserted between the substrate 11 and the right angle connector 13 as shown in FIG. The insertion / extraction direction of the wire harness 15 with respect to the right angle connector 13 is changed to an oblique direction (direction indicated by an arrow AR11) different from a direction parallel to the mounting surface 11a and a direction perpendicular to the mounting surface 11a.

  By adopting such mounting, in the board 11, even when the right angle connector 13 is disposed at a position other than the end of the board 11, the wire harness 15 can be easily inserted into and removed from the right angle connector 13 and the wire harness 15. It is also easy to avoid physical interference and electrical interference with the electronic components on the board 11 and the like.

  The shape of the spacer 12 is not particularly limited, but in FIG. 1, the side surface 12b is in contact with the mounting surface 11a, and the side surface 12a is the lower surface 13a of the right angle connector 13 (the mounting surface 11a without the spacer 12). A triangular prism-shaped member that is in contact with a surface that is in contact with the surface is illustrated. When such a triangular prism-shaped spacer 12 is employed, the angle formed by the side surfaces 12a and 12b defines the insertion / extraction direction of the wire harness 15 with respect to the right angle connector 13, and this angle is, for example, 10 ° to 70 °. Is desirable.

  As shown in FIG. 2, various electronic components including the connector 23 are mounted on the mounting surfaces 21 a and 21 b of the substrate 21 by soldering. More specifically, on the substrate 21, the surface mounting type electronic component 24 is placed on the lands formed on the mounting surfaces 21 a and 21 b and soldered, and the lead 23 </ b> L of the lead type connector 23. Are inserted and soldered into through holes formed so as to penetrate the mounting surfaces 21a and 21b. The various electronic components mounted on the substrate 21 are electrically connected by the wiring patterns formed on the outer layer (mounting surfaces 21a and 21b) and the inner layer of the substrate 21, and constitute an electronic circuit having a predetermined function. ing.

  Such a substrate 21 is, for example, a main substrate that performs overall control of the entire MFP, a scanner substrate that constitutes a reading unit that reads a document image and generates image data, and records an image based on the image data on a recording medium. And a communication control board for controlling connection with a communication line such as a general public telephone network and the like, and a wire harness 25 inserted into the connector 23. 2 shows an example in which a connector 26 that can be fitted to the connector 23 is attached to the tip of the wire harness 25. However, the wire harness 25 that is plated on the tip is directly connected to the connector 23. The adoption of the mode of inserting into the door is not hindered.

  The connector 23 is formed in a shape such that the insertion / extraction direction of the wire harness 25 with respect to the connector 23 is an oblique direction (a direction indicated by an arrow AR21) that is different from a direction parallel to and perpendicular to the mounting surfaces 21a and 21b. .

  By adopting such a connector 23, in the board 21, even when the connector 23 is arranged at a position other than the end of the board 21, the wire harness 25 can be easily inserted into and removed from the connector 23, and the wire harness 25 and the board 21 are also inserted. It is easy to avoid physical and electrical interference with electronic components on the top.
