Function and Effect of the Invention

<Invention of Claim 1> In the valve socket according to the invention of Claim 1, since the outer shell is formed by molding separately from the tubular portion, it is not necessary to cover the terminal fitting in order to mold the outer shell. Therefore, molding can be performed by a mold having a simple structure. Also, if there is a design change in the terminal fittings,
No modification of the mold is required, or it is kept only slightly. Therefore, the valve socket can be manufactured at low cost.

<Invention of Claim 2> First, a tubular body is attached to one end side of the terminal fitting, and a core body with a terminal fitting is formed in which a valve insertion port is formed which is shielded from the surroundings by the tubular body. After that, if this core body is insert-molded with the core material, a valve socket having a predetermined shape can be obtained. It is possible to obtain a highly accurate valve socket without excessive infiltration of resin without providing a portion for covering the terminal fitting in the mold.

<Invention of Claim 3> An L-shaped valve socket is manufactured by the following procedure. Initially, the terminal metal fitting is formed by straightening the connector terminal, and the connector terminal is inserted into the cylinder from the opening side, and the electrode terminal is housed in the cylinder and the connector terminal is projected to the outside through the terminal insertion hole. . Then, by bending the protruding portion of the connector terminal into an L-shape, a core body with an L-shaped terminal fitting is obtained. After that, insert molding is performed using the core body as a core material to obtain an L-shaped valve socket. L
The mold type valve socket can be manufactured with high precision and at low cost. <Invention of Claim 4> Since the bent portion of the connector terminal in the terminal fitting is formed by a single plate, the bending work can be easily performed.

<Invention of Claim 5> An L-shaped valve socket is manufactured by another procedure as follows. The terminal fitting is formed in advance with the connector terminal bent in an L shape. The terminal fitting is housed in the cylindrical body from the electrode terminal side through the terminal insertion hole, and the shielding plate shields the terminal insertion hole to obtain the core body. After that, insert molding is performed using the core body as a core material to obtain an L-shaped valve socket. Since the work of bending the terminal fitting is unnecessary, the process is simpler and the manufacturing cost is lower.

<Invention of Claim 6> Since the lightening groove is formed around the opening edge of the cylindrical body, the resin is more reliably prevented from entering the valve insertion port during insert molding, and further, the resin is further prevented. The movement of the core body due to the pressure is prevented, that is, the positional accuracy of the core body is improved, and more accurate manufacturing can be achieved.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. <First Embodiment> First, a first embodiment of the present invention will be described with reference to FIGS. In this embodiment, a valve socket 1 applied to a wedge base valve will be described. The valve socket 1 is composed of a core body 2 with a terminal fitting as a primary molded product and an outer shell body 3 as a secondary molded product with the core body 2 as an insert.

First, the core body 2 will be described (see FIGS. 2 and 3). The core body 2 is composed of a synthetic resin (for example, nylon resin) cylindrical body 4 and a terminal fitting 6 press-fitted therein. To be done. The tubular body 4 is formed into a straight rectangular tube shape that opens to one side (left side in FIG. 2), and this opening serves as a valve insertion port 5. Then, the pair of terminal fittings 6 can be housed in the tubular body 4. Further, a protrusion 7 is formed on the outer surface of the bottom of the tubular body 4, and a pair of terminal insertion holes 8 are formed on the bottom surface of the tubular body 4 so as to penetrate the protrusion 7, and the terminal fitting 6 The connector terminal 6E can be inserted without a gap. Further, an overhanging edge 9 is formed along the entire circumference on the outer peripheral edge of the bottom portion of the cylindrical body 4 to prevent mechanical disengagement with the outer shell body 3.

Next, the terminal fittings 6 housed in the tubular body 4 will be described (see FIGS. 4 and 5). Both terminal fittings 6 are formed by bending a conductive metal plate. , A wall plate portion 6A extending along the inner wall surface of the tubular body 4, and the wall plate portion 6A is formed with pressing pieces 6B cut inward and bent so that the wall plate portion 6A can be flexibly deformed. By making contact with the side surface of the base valve, rattling in the left-right direction of the valve shown in FIG. 6 can be restricted.
Further, a pair of long and short elastic pieces 6C and 6D are formed side by side by bending at a right angle from one side edge of the wall plate portion 6A.
The elastic piece on the longer side in the figure is the elastic locking piece 6C, which is locked to a wedge base valve (not shown) and serves to prevent the whole from coming off. Further, the elastic piece on the short side becomes a terminal piece 6D which can elastically contact both electrodes of the wedge base valve (not shown). These correspond to the electrode terminals of the present invention.

Further, after being bent inward at a right angle from the edge of the portion where the elastic locking piece 6C and the terminal piece 6D are formed, the connector terminal 6E is bent at a right angle outward. Has become. Initially, the connector terminal 6E is formed so as to extend straight and can be inserted into the terminal insertion hole 8 of the tubular body 4, but after being attached to the tubular body 4, it is bent at a right angle as shown by an imaginary line in FIG. . Further, the connector terminal 6E is inserted and embedded in the valve socket 1 and a portion related to connection with a power supply connector (not shown) are both closely bent from both sides to form a two-ply state. The bending target portion 6F located between them is left as a single plate, which facilitates bending work.

Next, the outer shell 3 will be described. The outer shell 3 is made of the same resin as that of the tubular body 4, and
The outer cylinder 10 has a rectangular tube-shaped outer cylinder 10 that covers the outer side surface and the bottom surface, and the valve body 11 and the outer cylinder 10 constitute a valve insertion portion 11. A lightening groove 12 is formed along the entire circumference between the opening edge of the outer cylinder 10 and the opening edge of the cylindrical body 4.
This prevents the molten resin from flowing into the cylindrical body 4 when the outer shell body 3 is molded, and receives the resin pressure so that the core body 2
Is to prevent the core body 2 from moving, that is, to improve the positional accuracy of the core body 2. A cylindrical portion 13 is arranged around the outer cylinder 10 so as to surround the outer cylinder 10, and the cylindrical portion 13 is continuous with the end of the outer cylinder 10 on the short piece side and lower than the outer cylinder 10. It is formed with a height. In addition, the core body 2 is the outer peripheral surface of the cylindrical portion 13.
4 retaining projections 1 at equal angular intervals near the opening of
4 is formed, and a flange edge 15 is formed so as to extend along the entire circumference near the bottom surface.

On the other hand, a connector insertion portion 16 is arranged on the bottom surface of the outer cylinder 10 so as to be continuous therewith. Connector insertion part 1
6 is arranged so that the mutual axis lines thereof are substantially orthogonal to the valve insertion portion 11 described above. This connector insertion part 1
6 is formed in a cylindrical shape, a connector insertion port 17 into which a power supply connector (not shown) can be fitted is opened at the tip, and the tip side of the connector terminal 6E of the terminal fitting 6 projects inside.

Next, the procedure for molding the valve socket 1 will be described. First, the cylindrical body 4 is formed by a molding die (not shown) (primary molding). With respect to the cylindrical body 4 thus obtained, the connector terminals 6E of the two terminal fittings 6
The sides are inserted into the terminal insertion holes 8 and exposed to the outside. The terminal insertion hole 8 has a hole diameter such that the connector terminal 6E can be inserted without a gap, and therefore the insertion portion is sealed to such an extent that molten resin does not flow in. After this, the tip side is bent at a right angle from the middle position of the connector terminal 6E.
In this case, the bent portion 6F of the connector terminal 6E
Is a portion that is not closely bent, so bending work can be easily performed. Thus, the core body 2 with the terminal fitting 6 is obtained.

Next, the core body 2 is mounted on the insert molding dies K1 to K3 to inject the molten resin (secondary molding). As a result, when the mold is opened after curing, the outer cylinder 10 and the cylindrical portion 13 surround the cylindrical body 4 with the core body 2 as the core material to form the valve insertion portion 11, and
A connector insertion portion 16 is formed so as to surround the connector terminal 6E of the terminal fitting 6 that is continuous with the valve insertion portion 11 and protrudes from the tubular body 4. Thus, the L-shaped valve socket 1 having a predetermined shape is obtained.

By the way, at the time of the secondary molding, the opening edge of the valve insertion port 5 is the molding surface 18 of the molding dies K1 to K3.
It is closed by this, and this covers the electrode terminal side of the terminal fitting 6 and prevents the molten resin from entering the cylindrical body 4. That is, since it suffices to close the opening of the tubular body 4, it is possible to prevent the molten resin from entering regardless of the shape of the terminal fitting 6. Therefore, it is not necessary to form a complicated cover part for covering the terminal fitting 6 in the mold, and simplification of the mold structure can be expected. This does not limit the shape of the terminal fitting 6 itself due to the relationship with the cover portion, so that the degree of freedom in design can be increased. Further, in particular, in this embodiment, the molding surface of the mold is formed with the projecting edge 19 for forming the lightening groove 12, and this is closely fitted to the outer peripheral surface of the tubular body 4, so that the molten resin is prevented from wrapping around. Thus, the infiltration of the resin into the cylindrical body 4 can be regulated more reliably. Further, movement of the core body 2 due to the resin pressure is prevented, that is, the positional accuracy of the core body 2 is improved, and thus more accurate manufacturing can be achieved. Since the terminal fitting 6 is inserted into the terminal insertion hole 8 of the tubular body 4 with almost no gap, the molten resin does not enter from here. Further, in this embodiment, since the protruding edge 9 is formed on the cylindrical body 4 to prevent the outer shell body 3 from mechanically coming off,
The joint strength between the cylindrical body 4 and the outer shell body 3 is enhanced, and the integral relationship between the both is reliably maintained.

As described above, according to the manufacturing method of this embodiment, since the core body 2 for accommodating the terminal fitting 6 is formed and then molded as an insert, the valve insertion port 5 It is possible to reliably prevent the molten resin from entering the inside of the cylindrical body 4 with a simple mold structure only by closing the. Also,
Since the terminal fitting 6 is bent at a right angle after being inserted into the tubular body 4, unlike the conventional case, the terminal fitting 6 does not become a two-member member, and therefore a configuration for connecting these is not necessary. Therefore, the structure of the terminal fitting 6 itself is not complicated. In addition, since the terminal fitting 6 can be used as it is, the strength of the terminal fitting can be maintained.

<Second Embodiment> FIGS. 8 to 14 show a second embodiment of the present invention.

On the lower surface side of the shielding plate 33,
Wall plate portions 34 are formed along the inner surfaces of the left and right side walls of the tubular body 24 so as to be bent from the outer edges and project downward. Inside the wall plate portions 34, a pair of electrode terminals 35 that are in contact with each other while elastically sandwiching the electrode portion of the wedge base valve are formed to face each other in the front-rear direction. The pair of electrode terminals 35 can be inserted along the front and rear inner side surfaces of the tubular body 24. On the other hand, on the upper surface side of the shield plate 33, a connector terminal 36 is formed which rises from the inner edge of the shield plate 33 and is then bent at a right angle to project in a tab shape.

That is, each of the terminal fittings 32 is formed in a substantially L-shape as a whole, and as shown by the arrow in FIG.
Is inserted from above into the terminal insertion hole 28 from above, and the wall plate portion 34 and both electrode terminals 35 are pushed in while making elastic contact with the inner side surface of the cylindrical body 24, so that the shielding plate 33 is When it comes into contact with the upper surface of the tubular body 24, it is attached to the tubular body 24 in a state where it cannot be easily removed. Along with this, each shielding plate 33 shields the upper surface of the terminal insertion hole 28, and the tips of the electrode terminals 35 slightly project from the lower edges of the front and rear side surfaces of the cylindrical body 24 so that they can be flexibly deformed outward. Has become.

Next, the outer shell 23 will be described. The outer shell 23 is made of the same resin as that of the tubular body 24.
The outer cylinder 37 has a rectangular outer cylinder 37 that covers a part of the upper surface of FIG. 8 from the outer surface of the cylindrical body 24. The cylindrical body 24 and the outer cylinder 37 form a valve insertion portion 38.
