Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coaxial connector 6 mounted directly on a printed board.

FIGS. 1 and 2 and 5 show how to mount a conventional printed board mounting connector on a printed board 1.

In the case of Figure 1, the coaxial connector 1 has a metal fitting 2 for installation; &2 with screw sC = printed board 4 (:I).

The inner conductor 5 and the outer conductor 6 are connected to the pattern ζ of the printed board 4 via the strap wirings 7 and 8, respectively, and the printed board 4ζ:* is mounted.

In addition, in the case of FIG. 2, the coaxial connector 9 includes the inner wall 1: the outer periphery of the outer conductor integral 11 holding the outer conductor spring 10 (:
Fig. 3 6 = Details - As shown (: When the U-shaped strip-shaped external conductor terminal 12 is fitted and connected by soldering etc. ζ:
, the center C of the main body 11 of the external conductor: the internal conductor 14 is held through the insulating member 15, and the outside thereof is molded 15,
16. External conductor terminal 12.
The ends of the inner body 14 (: formed connections 17.18 protrude from the shield 15.16. This coaxial connector 9 connects each connection 17.18 to a through hole ζ of the printed board 19: Insert seven leads 15 and 14 onto printed board 1.
The mold 15 is fixed to the printed board 19 using screws 20 (=), and the connecting portions 17 and 18 are soldered to the through holes and mounted on the printed board 19.

These conventional coaxial connectors C: had various drawbacks as follows.

In other words, in the case of the coaxial connector 1 shown in Fig. 1, it is attached to the printed board C via the metal fitting 2, making it difficult to downsize, and furthermore, the connection to the printed board is made via strap wiring, which increases the cost. .

In addition, in the case of the coaxial connector 9 shown in FIG. 2, the structure is complicated (
: and since the external conductor terminal 12 has flexibility,
The connector requires a mounting structure to the board (a bolt 15 is required for fixing with two screws).

The present invention is intended to solve the above-mentioned various drawbacks, and an object of the present invention is to provide a printed board straight-cut coaxial connector that is small in size, simple in structure, and low in cost.

Hereinafter, the present invention will be described in detail with reference to FIGS. 4 to 7.

Fig. 4 is a front sectional view showing a state in which a printed board direct-mounted coaxial connector according to the present invention-2 is mounted on a printed board, and Fig. 5 is a side view of the same, in which numeral 21 is a coaxial connector and 22 is a printed board. It is.

The coaxial connector 21 includes a mold 24 that holds a center part 1 inner conductor 23, and an outer periphery of an outer conductor spring (outer conductor) 25 (Nispot welding, etc. 1: more electrical).

Mechanically connects the two connected cylinders 101 to the inner can and molds 246 through the base of the outer conductor spring 25 and the spool 101.
It consists of two fitting molds 26 and a shield holding metal 27 which also serves as an external conductor metal fitting.

The mold 26 has a circular mold holding tool 27 for inserting the plug-side connector, and the upper plate 294 has two plates as shown in FIG. The upper plate 29ε is provided with a hole 31 and a bent fork-like engagement 1152 on the lower side, and each side plate 30
S= is provided with a hole 33 and a connecting portion 54 extending downward. - This mold holding fitting 27 is fitted from above the mold 24.24, and protrusions 35I protrude from both sides of the mold 24 as shown in detail in FIG. i5 is fitted, and the protrusion 36C protruding from the upper surface of the mold 26: the hole 51 of the upper plate 29 is fitted and integrated with both molds 24 and 26. At this time, the groove of the retaining part 32! i2m is 1o14: a protrusion provided to protrude from the base of the outer conductor spring 250, 57 (
': This fitting part is soldered. Therefore, the external conductor spring 25 and the mold holding fitting 27 are electrically connected to each other. In addition, in this state, the mold holding metal fittings 2
The connecting portion 34 of No. 7 protrudes below the mold 26, and the connecting portion 58 formed at one end C of the internal conductor 26 protrudes below the mold 24.

The coaxial connector 21 according to the present invention is configured as described above, and the mold 24 that holds the inner conductor 23 and the mold f26 that holds the outer conductor spring 25 are connected to the mold holding tool 27 that is connected to the outer conductor spring 25. The structure is simpler and the cost can be reduced compared to the conventional case of the second @. Furthermore, since there are no metal fittings in the conventional mounting as shown in FIG. 11, the size can be reduced.

Printed board 221 of coaxial connector 21 having such a configuration
Loading on : is done by the following procedure (:).

That is, each connection part 54, 58 is inserted into the printed circuit board 22, each mold 24, 26 is placed on the printed board 22, and the connection part 34 is inserted into the printed board 22 as shown in FIG. The coaxial connector 21 is mounted by bending and soldering the back surface of the plate 22 and by soldering the connecting portion 58 through the hole.

In this way, the coaxial connector 21 is mounted on the printed circuit board 22 using each connection part, and strap wiring and mounting screws are not required, so the mounting is easy and costs can be reduced.

As described above, according to the present invention (=), it is possible to achieve the following various excellent effects.

(1) Miniaturization can be achieved.

(2) The structure can be simplified.

(3) It is possible to reduce costs.
