Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for attaching a connector to a case of an electronic device such as a car phone.

[0002]

[Prior art]

 A conventional example of a mounting structure for this type of connector is shown in FIG. 4 and briefly described below. In FIG. 4, a socket-type (female-type) connector 3 having an insertion opening (not shown) on the front side is exposed to the outside in an opening 2a formed in a side surface of a case 2 of electronic equipment. It is located in.

First, the connector 3 is fixed by screws 6 to a pair of left and right boss portions 2b that are provided to project inside the case 2. A printed wiring board 5 is arranged above the rear part of the connector 3 in parallel with the connector 3, and the printed wiring board 5 is in a state in which a plurality of terminals 3a provided on the connector 3 are inserted from the lower side of the printed wiring board 5. The screws are fixed to a pair of left and right boss portions 2c protruding from the case 2 which are relatively tall. The terminals 3a of the connector 3 are soldered 5a to the board 5.

[0004]

[Problems to be solved by the device]

 In the conventional connector mounting structure as described above, the connector 3 and the substrate 5 are separately mounted in the case 2 and then soldered. (1) Assembling work is troublesome Takes time. Also, care must be taken not to damage the case during the soldering work, which is also troublesome. (2) Since the boss portion 2c for fixing the boss portion 2c is required directly below the substrate 5, there are problems that the layout of the component is apt to be restricted and the material cost for the boss portion 2c is increased.

In view of the above points, the present invention makes it easy to assemble the components and perform the assembling work, and makes it possible to effectively use the assembling space of the board, which can further reduce the cost. The purpose of the present invention is to provide a connector mounting structure that can achieve various effects such as.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a connector mounting structure according to the present invention is a mounting structure for mounting a connector to a case of electronic equipment, wherein the connector is fixed to a bracket and a wiring board is mounted on the bracket. Is fixed to form a unit, and the unit is fixed to the case.

[0007]

[Action]

 In the connector mounting structure of the present invention configured as described above, the connector and the wiring board are fixed to the bracket, these three members are assembled into one unit, and the case in the state of the unit is assembled. Since it is fixed to, the handling of the components becomes easy and the assembly work becomes easy.

[0008] Furthermore, since the three members are assembled into one unit and fixed to the case as described above, there is no need for a boss portion to fix the unit directly below the board, and the free space on the component layout is eliminated. As a result, the board mounting space can be effectively used.

[0009]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a connector mounting structure according to the present invention. In the figure, portions corresponding to the respective portions of the conventional example shown in FIG. 4 described above are denoted by the same reference numerals, and duplicate description thereof will be omitted.

As can be seen by referring to the exploded perspective view of FIG. 3 in addition to FIG. 1 and FIG. 2, the connector mounting structure of the present embodiment has a case 2 for electronic devices, a connector 3, a printed wiring board, and the like. The unit 10 including the bracket 5 and the bracket 12 is attached.

That is, the connector 3 is provided with an insertion port 3c on the front surface thereof, into which a connector (plug) to be connected is attached, and screw insertion holes 3b, 3b are formed on both sides, and the board 5 is also provided. Also, screw insertion holes 5b, 5b for mounting and fixing are formed. The bracket 12 is formed by bending a metal plate, and has a crank shape in side view (FIGS. 1 and 2) and a generally U-shape in plan view (FIG. 3), and both side portions thereof. A pair of screw insertion holes 12a, 12b, 12c are formed in each.

When the connector 3, the board 5, and the bracket 12 are assembled into the unit 10, first, as shown in FIG. 3, the tip of the board 5 is inserted into the bracket 12, and the pair of screw insertion holes described above are inserted. As shown in FIG. 2, the bracket 12 and the board 5 are fixed through the screws 12c, 5b, 12c and 5b, and then the terminal 3a of the connector 3 is inserted into the through hole of the corresponding printed wiring of the board 5. , The connector 3 is fixed to the bracket 12 with the screw 13 through each pair of screw insertion holes 3b, 12a, 3b, 12a, and then soldered 5a to the back surface of the board 5 or surface mounted on the board 5. In this case, one unit 10 is constructed by soldering the terminals 3a of the connector 3 to the corresponding wiring patterns on the surface of the substrate 5 (not shown). As shown in FIG. 3, this single unit 10 is fixed to the boss portion 16 projecting on the case 2 through the screw insertion holes 12b and 12b of each pair of the bracket 12 with the screws 14. In this case, the board 5 may be above or below the connector 3, but it is arranged below in the figure.

In the connector mounting structure of this embodiment having such a configuration, the connector 3 and the wiring board 5 are fixed to the bracket 12, and these three members are assembled into one unit 10. Since the unit 10 is fixed to the case 2 in the state, the components can be easily handled, the assembling work can be simplified, and the cost can be reduced due to the simplification.

Further, since the board 5 is fixed to the case 2 via the bracket 12, there is no need for a boss portion for fixing the board 5 directly under the board 5, so that the degree of freedom in component layout is increased, and the board layout is improved. Since the assembling space can be effectively used, there is no need for a boss portion for fixing the space directly below the substrate as in the conventional case, and the effect that unnecessary bosses can save the member cost can be obtained.

Furthermore, since the bracket 12 is interposed between the connector 3 and the board 5, and is fixed to the case 2 via the bracket 12, almost no load is applied to the connector or the board 5. Therefore, it is possible to prevent peeling of the printed wiring at the soldering 5a portion.

If the end edge of the bracket 12 is bent, the rigidity of the bracket 12 itself, especially the bending strength in the thickness direction is improved, and the unit 10 becomes extremely sturdy.

Furthermore, in the above description, the case of electronic devices such as a car telephone is described, but if it relates to the structure for attaching the connector in the case where the connector is arranged so as to face the outside, It goes without saying that the present invention is applied.

[0018]

[Effect of device]

 As is clear from the above description, according to the connector mounting structure of the present invention, the components can be handled easily and the assembling work can be performed easily, and the degree of freedom in the layout of the components in the case can be increased. It is also possible to obtain various effects such as an improved use of the board, a space for assembling the board effectively, and a cost reduction.
