Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to fixing means for a right angle printed board connector to a printed board and fixing means for a jack side or plug side connector to be inserted. This relates to improvement of the fixing structure.

(b) Technical background To connect the circuit pattern on the printed board to an external circuit,
There is a method in which terminals of a right-angle connector are connected to through-holes formed in a circuit pattern at the edge of a printed board, and a plug-side or jack-side connector connected to an external circuit is inserted into the right-angle connector.

In this case, in order to prevent the terminals of the right-angle connector from being damaged by external force, it is necessary to fix the right-angle connector to the printed board.

On the other hand, in order to prevent the plug-side or jack-side connector from being pulled out, it is necessary to removably fix the plug-side or jack-side connector to the right-angle printed board connector with a screw.

(C) Prior art and problems Figure 1 shows a conventional fixing structure, A is a perspective view, the mouth is a detailed view showing the dotted frame M part in A separated, and Figure 2 shows another conventional fixing structure. FIG. 2 is a partially sectional perspective view showing key points.

In FIG. 1, reference numeral 2 denotes a right-angle connector (on the plaque side) that is attached to the edge of the printed board 1.

At both ends of the rectangular insulator 6 of the connector 2, substantially cubic convex portions 7 whose bottom surfaces are in close contact with the top surface of the printed board 1 are formed.

An insertion hole 8 is bored in the convex portion 7 directly to a hole (not shown) in the printed board.

A screw hole 11 corresponding to the insertion hole 8 is provided in the front plate part of the upper plate part of the fixing fitting 6 made of a metal material in a side view shape in which the upper surface of the convex part 7 is in close contact with the front surface, and the inner corner surfaces thereof are in close contact with each other. is screw hole 1
0 is stamped on each.

After fitting the right-angle terminals 2' of the connector 2 into the through holes of the printed board 1, place the fixing metal fittings 9 on the convex portions 7, and insert the machine screws 5 into the insertion holes 8 from the back of the printed board 1. and screw it into the screw hole 11.

In this way, the connector 2 is fixed to the printed board 1.

To fix the jack side connector 3 to the connector 2, after inserting the jack side connector 3 into the connector 2,
The fixing screws 4 are screwed into the screw holes 10 of the corresponding fixing fittings 9, respectively.

In FIG. 2, bushes 14 and 13 each having a screw hole formed in the central shaft portion are press-fitted at both ends of the insulator 12 at positions corresponding to the screw holes 11 and 1G of the fixing fitting 9 in FIG. .

A machine screw 15 is screwed into the screw hole of the bushing 14 from below the printed board 1 to fix the insulator 12 to the printed board 1.

The screw hole of the bushing 13 is a screw hole into which the fixing screw 4 shown in FIG. 1 is screwed.

However, the screw hole of the fixing fitting 9 shown in FIG. 1 requires a required number of threads, and therefore requires a desired thickness.

Therefore, it is formed into an L-shape by cutting from a square block material, which may increase the material and processing costs.

Furthermore, the one shown in FIG. 2 is complicated in that two bushings 13 and 14 (-) must be press-fitted into the insulator.

Furthermore, in both cases, the insulator must be provided with a hole 8 orthogonal to the direction in which the jack side connector is inserted, or a hole into which the bushing 14 is inserted.

This poses a problem in that the mold used for molding the insulator becomes extremely complex, resulting in increased costs for the mold and the insulator.

(d) Purpose of the invention In view of the above-mentioned conventional problems, the purpose of the present invention is to provide a low-cost fixing structure for a printed board connector by improving the shape of the fixing fitting.

(e) Structure of the invention In order to achieve this objective distantly, the present invention has a rectangular slit which is opened in the front where the jack side or plug side connector is inserted, and which is fixed to the printed board and runs parallel to the printed board. However, the printed board connector main body provided at both ends of the insulator and the claws protruding from both side edges fitted into the slit bite into both sides of the slit, and the insertion plate part fitted into the connector main body. U-shaped or L-shaped made of formed metal plate
The front plate of the fixing fitting has a screw hole into which a fixing screw attached to the jack side or plug side connector inserted into the printed board connector is screwed, and The insertion plate part is provided with a terminal that fits into the hole of the printed board, or a screw hole into which a fixing screw passing through the hole is screwed.The fixing metal fittings are formed by plastic processing a thin plate, and each The screw hole is formed by threading the inner circumferential surface of the hole of the protrusion that is made to protrude by burring.

(f) Embodiments of the invention The invention will be described in detail below with reference to illustrated embodiments.

Note that the same reference numerals indicate the same target parts throughout the figures.

Fig. 3 shows one embodiment of the present invention, A is a perspective view, the opening is a detailed view of the part N in the dotted line frame A, and Fig. 4 is another embodiment of the present invention, A is a perspective view of the fixing fitting, and the opening is the attached part. FIG. 5 is a perspective view of the fixing metal fitting of still another embodiment, and the opening is a sectional view of the attached part.

In Figure 3, 16 is a right angle printed board connector (plug side) main body, which is fitted into a through hole in the printed board (not shown) and soldered to the rear side of the rectangular insulator. A large number of right angle terminals 18 protrude in parallel.

Reference numeral 22 denotes a fixing metal fitting made of a thin metal plate plastic-processed into a substantially U-shape. A protrusion 28 that is barred backward is formed at approximately the center of the front plate portion 23, and a jack (not shown) is formed on the inner peripheral surface of the protrusion 28. Fixing screws (first
A screw hole 27 is threaded into which the fixing screw 4) shown in the figure is screwed.

The upper part of the front plate part 23 is bent and has a substantially rectangular shape in plan view.
Claws 26 are formed at symmetrical positions protruding from the direction (viewed from the direction).

Also formed at the lower part of the front plate part 23 is a lower fitting plate part 25 parallel to the fitting plate part 24 having claws 26 .

At approximately the center of the tip edge of the insertion plate portion 25, a thin strip is bent downward and inserted into a hole in a printed board (not shown).
Terminals 29 to be soldered are formed.

At both ends of the front side of the insulator 17, a rectangular recess 19 is formed in front view into which the front plate part 23 is fitted, and the recess 19
A recess 20, which is a recess for the protrusion 28, is formed in the center of the recess 20.

At the upper and lower portions of the recess 19 are fitted plates whose left and right widths are approximately equal to the width of the front plate portion 23 and whose thickness is approximately equal to that of the fitted portions 24.25 and whose depth is longer than the length of the fitted portions 24.25. slits 18 into which portions 24 and 25 fit respectively;
are formed perpendicularly to the front side surface of the insulator 17.

Therefore, when the fixing metal fittings 22 are press-fitted into the insulator 17, the claws 26 bite into the left and right side surfaces of each slit 18 and are fitted, so that the fixing metal fittings 22 do not fall off from the printed board connector main body 16.

A slit 21 is formed below the center of the slit 18 under the insulator 17 so as not to become an obstacle to inserting the terminal 29 from the front side.

The printed board connector main body 16 is fixed to the printed board by fitting the terminals 29 into the holes of the printed board and soldering them.

As described above, since the recess 19, the recess 20, the slit 18, and the slit 21 are all open to the front side, the mold for molding the insulator 17 has a simple structure.

Furthermore, the fixing fittings 22 can be manufactured by plastic processing a thin metal plate, resulting in low cost.

In FIG. 4, the fixing fitting 30 is the fixing fitting 2 of FIG.
2 with the upper insertion plate part 24 removed.

Therefore, the insulator 17 is provided with a slit into which the lower insertion plate portion 25 is fitted, and the upper slit is not required.

All other structures such as the terminal 29 fitting into the hole 31 of the printed board 1 and being soldered are the same as in FIG. 3.

The structure shown in FIG. 4 has a lower cost than that shown in FIG.

In FIG.
6. It is the same as the one shown in FIG. 4, except that a screw hole 37 is formed, there is no upper fitting plate part, and a lower fitting plate part 34 and pawls 35 are provided.

However, there is no terminal 29, and the approximately central part of the insertion plate part 34 is burred downward to form a protrusion 38, and a fixing screw 40 that penetrates the hole 39 of the printed board 1 from below is screwed into the inner peripheral surface of the protrusion 38. A screw hole 41 is threaded therein.

The fixing screw 40 fixes the printed board connector body to the printed board 1.

(g) Effects of the invention As explained above, the present invention integrates the fixing fitting made of a thin metal plate into the slit of the insulator of the printed board connector main body by fitting it into the slit of the insulator of the printed board connector body, and attaching the fixing fitting to the printed board connector body.
