And each leg 14 is inserted into the base B, bent, and pressed to be attached to the base B.

挿通し、ポンチP’によってその脚4を外側に折曲し、
ベースBに圧接して行っている。In the conventional mounting of the connector C, as shown in FIG. 10b, the leg 4 is inserted into the base B, and the leg 4 is bent outward by the punch P '.
It is pressed against the base B.
【0006】この圧接時、ポンチP’が脚4を介在して

ととなる。この一側での抵抗は十分でない場合が多い。Further, as shown in FIG. 9b, when the leg 4 has a mounting structure in which the leg 4 is bent outward, for example, when an external force acts as indicated by an arrow, the leg 4 (point a portion) on the front side is chained. Thus, the leg 4 on the opposite side (point b portion) resists the external force as it goes away from the base B as it is. The resistance on this one side is often not sufficient.

求項1)。In order to solve the above-mentioned problems, according to the present invention, a connector in which a cylindrical external terminal is filled with resin and an internal terminal is provided on the central axis of the resin, In the above-mentioned structure attached to a plate-shaped base of an electric device, a plurality of legs are provided at the mounting end of the external terminal to the base at required intervals around the base, and holes are respectively inserted into the base. Is formed, each leg of the external terminal is inserted into each of the holes, the mounting end is in contact with the base, and each leg is bent toward the internal terminal side and pressed against the base, The connector is fixed to the base by pressure contact of the legs (Claim 1).
【0011】この構成において、上記ベースの各孔に囲

The legs firmly hold the base, and when an external force acts on the connector,
Many legs effectively resist preventing the connector from disengaging from the base (see description of Figure 9a below).

(後述の図10aの説明参照)。If the inside of the base surrounded by the leg insertion holes is bulged, when the punch is bent, the leg is bent by pressure contact with the bulging portion until the punch abuts the base. Therefore, sufficient leg bending (caulking) is performed (see the description of FIG. 10a described later).

As shown in FIGS. 1 to 4, the connector C has a cylindrical external terminal 11 filled with resin (insulator) 12, The internal terminal 13 is provided on the cylinder center (on the central axis) of the insulator 12. At the mounting end 11a of the external terminal 11 to the base B, legs 14 are provided so as to protrude at four equal intervals around it. The number of legs 14 and the distance between them can be arbitrarily set in consideration of the mounting strength.

膨出させる必要はない。A hole 15 through which the leg 14 of the external terminal 11 is inserted is formed in the mounting frame (base) B on the television receiver side, and the inside of the hole 15 is bulged, and the bulged portion 16 is formed. A through hole 17 for the internal terminal 13 is formed in the center of the. The degree of bulging may be appropriately selected in consideration of the degree of crimping (pressure contact) of the legs 14 described later, but it is not always necessary to bulge.

になされる高さを確保するように設定する。This connector C has legs 14 of its external terminals.
Through the hole 15 of the frame B so that the mounting end 11a is brought into contact with the frame B, and as shown in FIG. 10a, the leg 14 is bent inward by the punch P and pressure-contacted with the bulging portion 16 (caulking).
By doing so, the mounting end 11a of the external terminal 11 and the leg 1
The bulging portion 16 is clamped at 4 and attached to the frame B. At this time, as shown in the figure, the punch P bends and presses the leg 14 between the punch P and the bulging portion 16 with which the mounting end 11a abuts, so that the crimping (pressing) is reliably performed. That is,
Since the crimping action is completed before the punch P touches the frame B, the pinch P ′ does not come into contact with the frame B and the crimping action is not insufficient as in the conventional case shown in FIG. For this reason, the degree of bulging of the bulging portion 16 is set so as to ensure a height at which the crimping action is surely performed.

い。Further, as shown in FIG. 9a, when the leg 14 is bent inward in this way, when an external force is applied as indicated by an arrow, the leg 14 is disengaged from the point a as a fulcrum. The leg 14 resists the external force and b on the opposite side
The leg 14 of the point also bends like a chain line in order to come off the hole 15, and therefore resists the external force. That is, as in the conventional case shown in FIG.
Since the leg 14 at the points a and b resists the external force by itself instead of resisting the external force by itself, the connector C is not easily separated from the frame B.

The holding of the base B by means of FIG.
Of the mounting end 11a to the connecting portion 16a of the
6 is performed by press-fitting the leg 14 to the corresponding portion 16b of the hole 15 and pressing the bulging portion 16 alternately from one surface over the entire circumference, so that the bulging portion 16 is bent in a full-frequency manner. It will be in the state where it was set. Therefore, due to the bending, the mounting end 11
The pressure contact force between a and the bulging portion 16 of the leg 14 is promoted, and the connector C is firmly attached to the base B.

As shown in FIG. 5, the plate terminal 11 ′ having the planar shape of the external terminal 11 is punched from one band-shaped plate by press working in a state of being connected to the band-shaped carrier 22 and the ridge 18 is extruded. . As shown in FIG. 6a, the extrusion molding is performed by forming a ridge 30a or a ridge 31 having a sectional shape of the ridge 18.
a punch 31 having a and a die 31. As shown in the drawing, the plate 11 'is placed on the die 31 and the punch 3
By pressing 0, the plate-like body 11 'is plastically deformed like a chain line to obtain the protrusion 18 shown in FIG.
The ridges 18 have substantially the same thickness and are sufficiently strong. Further, as can be seen from the figure, the ridge 18 has a triangular cross-section and resembles a screw thread. The number of external terminals 11 punched at one time is arbitrary. In addition,
At the time of punching, the legs 14, the locking holes 20, and the positioning holes 19 corresponding to the external terminals 11 of each external terminal 11 are simultaneously formed.

Then, as shown in FIG. 8, the external terminal 11 is put into the molding die w, and the resin a is injected from the one locking hole 20 to insert-mold the insulator 12 and the protrusion 12b. At this time, the pin 21 is inserted into the hole 19 for positioning. The number of external terminals 11 to be insert-molded is arbitrary.
