Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for fixing and holding an antenna jack with respect to a case.

[0002]

[Prior art]

 Conventionally, when attaching a jack such as an IEC jack for an antenna to a case or the like, a mounting structure as shown in FIG. 3 has been adopted. That is, in FIG. 3, the mounting structure includes a case 1 and an antenna jack 2 to be mounted in the case.

The case 1 has a mounting hole 1 a provided on the upper surface thereof. On the other hand, the upper jack 2a of the antenna jack 2 is formed hollow so as to receive the antenna plug, and the lower tip 2b thereof is formed relatively thin. The portion 2b can be inserted into the mounting hole 1a of the case 1.

When the antenna jack 2 is attached to the attachment hole 1a of the case 1, as shown in FIG. 4, the ring solder 3 is first attached to the tip portion 2b of the antenna jack 2. After fitting, the tip portion 2b of the antenna jack 2 is then inserted into the mounting hole 1a of the case 1.

From this state, the entire case 1 is passed through the reflow furnace, whereby the above-mentioned ring solder 3 is melted, whereby the tip portion 2 b of the antenna jack 2 is attached to the mounting hole 1 a of the case 1. Therefore, the antenna jack 2 can be attached to the case 1.

According to the mounting structure thus configured, the antenna jack 2 is mounted to the case 1, and then a board or the like having a predetermined circuit is assembled in the case 1. After that, the whole case 1 is again passed through a reflow furnace, or a predetermined solder such as the above-mentioned board is soldered by dipping.

[0007]

[Problems to be solved by the device]

 However, in the mounting structure configured as above, the antenna jack 2 soldered to the case 1 by the ring solder 3 once melts at the solder joint portion in the reflow process or the dipping process again. I will end up.

By the way, since the antenna jack 2 is not temporarily fixed to the mounting hole 1a of the case 1, the antenna jack 2 may be displaced or tilted with respect to the case 1. However, it was necessary to solder the antenna jack 2 again, which made the assembly work complicated and troublesome.

In view of the above points, the present invention temporarily fixes the antenna jack to the case so that the antenna jack is soldered to the case at the time of reflow, dipping, or the like of the case. It is an object of the present invention to provide a mounting structure for an antenna jack, which prevents the antenna jack from being displaced or tilted even if the joint is melted.

[0010]

[Means for Solving the Problems]

 According to the present invention, the tip of the antenna jack is inserted into the mounting hole provided in the case from the outside, and the tip is ring soldered to the area of the mounting hole of the case. In the antenna jack mounting structure, in which the antenna jack is mounted to the case by soldering the antenna jack to the case, with the tip of the antenna jack fitted with the ring solder, After being inserted into the mounting hole of the case, the tip portion is temporarily fixed to the mounting hole of the case by crimping using a jig or the like, and then when reflow soldering to the case, The antenna jack is characterized in that when the ring solder is melted, the antenna jack is soldered and fixedly held in the mounting hole of the case. The mounting structure is achieved.

[0011]

[Action]

 According to the above structure, after the antenna jack is temporarily fixed to the mounting hole of the case by caulking, the ring solder fitted on the tip of the antenna jack is melted by reflowing or the like, Since the antenna jack can be attached to the case, the antenna jack can be used when soldering is performed by reflow, dipping, or the like on the board or the like incorporated in the case. Even if the solder joint in the case mounting hole is melted, the antenna jack is temporarily fixed to the case mounting hole by caulking, so it does not slip or tilt with respect to the mounting hole. There is no need to re-solder because it is surely held at the predetermined position with respect to the mounting hole. So that there is no, the assembly can be easily performed.

[0012]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of a structure for mounting an antenna jack according to the present invention.

The mounting structure 10 is composed of a case 11 and an antenna jack 12 to be mounted on the case 11.

The case 11 has a mounting hole 11a provided on the upper surface thereof, and the upper portion 12a of the antenna jack 12 is formed hollow so as to receive the antenna plug. At the same time, the lower end portion 12b is formed relatively thin, and the thin end portion 12b can be inserted into the mounting hole 11a of the case 11.

The above structure is similar to the conventional mounting structure shown in FIGS. 3 and 4, but in the mounting structure according to the present invention, the tip portion 12b of the antenna jack 2 is the case 11. After being inserted into the mounting hole 11a, the tip portion 12b is temporarily fixed to the mounting hole 11a of the case 11 by caulking by using a jig or the like.

The mounting structure 10 according to the present invention is configured as described above. When the antenna jack 12 is mounted in the mounting hole 11a of the case 11, the tip of the antenna jack 12 is first attached. The ring solder 13 is fitted on the portion 12b, and then the tip portion 12b of the antenna jack 12 is inserted into the mounting hole 11a of the case 11.

From this state, by using an appropriate jig or the like, the lower edge of the tip portion 12b of the antenna jack 12 is partially cut open as shown in FIG. Is bent outward and the tip 12c engages with the inner surface of the mounting hole 1a of the case 1, so that the antenna jack 12 is temporarily fixed to the case 11 by so-called caulking.

After that, the entire case 11 is melted by the reflow process or the dipping process to enter between the tip portion 12b of the antenna jack 12 and the mounting hole 11a of the case 11. The tip portion 12b of the antenna jack 12 is soldered to the mounting hole 11a of the case 11. Thus, the antenna jack 12 can be attached to the case 11.

Here, when the board or the like is built in the case 11 and the board is soldered in the reflow process or the dipping process, the mounting hole 11a of the case 11 of the antenna jack 12 is simultaneously formed. Although the solder joint to the case will also be melted, since the antenna jack 12 is temporarily fixed to the case 11 by caulking, it may be displaced or tilted with respect to the case 11. Instead, it can be held securely in place.

[0020]

[Effect of device]

 As described above, according to the present invention, by temporarily fixing the antenna jack to the case, the solder joint portion of the antenna jack to the case is reflowed or dipping. Even if the antenna jack is melted, it is possible to provide a mounting structure for the antenna jack that prevents the antenna jack from being displaced or tilted.
