Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a valve socket,
And a terminal for a valve socket.

[0002]

2. Description of the Related Art Some valve sockets are generally L-shaped and have a connector housing portion for housing a power supply side connector and a valve housing portion for housing a valve opened in a direction substantially perpendicular to each other. In the case of such an L-shaped valve socket, the valve terminal connected to the valve and the connector terminal connected to the power supply side connector are assembled into the socket body as separate parts, and the ends of both terminals are connected to each other. Are connected to form an overall L-shape.

An example of such an L-shaped valve socket is disclosed in Japanese Patent No. 3178185. In this valve socket 100, the connector terminal 101 is formed into a substantially L shape by bending one end of a conductive metal plate material upward at a right angle, and this bent portion serves as a connection tab 102. On the other hand, the valve terminal 111 includes a square tube portion 112 that receives the connection tab 102 of the connector terminal, and an elastic pressing piece 113 that is provided inside the square tube portion 112 and elastically contacts the connection tab 102. (Fig. 20).

The connector terminal 101 has a connector accommodating portion 1
When the valve terminals 111 are accommodated in the valve accommodating portion 122, the square tube portion 11 of the valve terminal 111 is accommodated.
The connection tab 102 of the connector terminal 101 is inserted into the connector 2. Then, the connection tab 102 is pressed between the elastic pressing piece 113 and the inner wall surface of the rectangular tube portion 112 by the elastic force of the elastic pressing piece 113. As a result, the connector terminal 101 and the valve terminal 111 are joined so as to be electrically conductive with a predetermined contact pressure.

[0005]

However, when the connection tab 102 is formed by bending a metal plate material as described above, it is known that a slight return occurs after the bending process (spring back). Therefore, in bending, the return angle due to the springback is taken into consideration in advance and bending is performed by adding that amount. However, since the return angle varies from terminal to terminal 101, the bending angle L may be incorrect. When this deviation is large, there is a problem that the tip of the connection tab 102 is caught by the elastic pressing piece 113 of the valve terminal 111, and the connection tab 102 cannot be inserted into the square tube portion 112.

Here, a terminal insertion port 123 provided in the connector accommodating portion 121 for receiving the connector terminal 101.
Are formed to have substantially the same size as the plate surface of the connection tab 102, and the connector terminal 101 is
The second side is set to the back side and inserted into the connector accommodating portion 121 from the terminal insertion port 123 (FIG. 21). Therefore,
Regardless of the bending angle L, the connector terminal 101 passes through the terminal insertion port 123 and the connector accommodating portion 121.
It will be inserted inside. Therefore, the valve socket 10
At the stage of attaching the connector terminal 101 to 0, it is not possible to recognize whether the bending angle L of the connector terminal 101 is good or bad, and it may be defective only when the connector terminal 101 and the valve terminal 111 are connected. It was known.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to detect a defective terminal in advance and prevent a defective connection with a mating terminal, and a valve socket. It is to provide terminals.

[0008]

In order to solve the above-mentioned problems, a valve socket according to the invention of claim 1 comprises a valve accommodating portion for mounting a valve and a connector accommodating portion for fitting a power supply side connector. Socket bodies that are provided at substantially right angles to each other, a valve terminal that is inserted into the socket body from the valve housing portion side, and a connector terminal that is inserted into the socket body from the connector housing portion side. In the socket body, any one of the terminals is put into a corresponding accommodating portion in a standby state, and the other terminal is inserted into the corresponding accommodating portion, and the insertion operation is performed. A valve socket to which both terminals are connected, wherein the one terminal is provided with a flat plate-shaped main body, and a side plate provided on the main body is bent. The plate surface of the main body portion so as to intersect with the plate surface of the main body portion, and the joint portion that can be connected to the other terminal and the joint portion that is extended to the side of the joint portion. And a connection portion that connects the main body portion to each other, and a connection portion that connects the main portion to the main body portion is provided. In the storage portion on a side corresponding to the one terminal of the both storage portions, the one terminal is a bent edge of the connection portion. Is inserted with the direction along the
And, when the angle between the plate surface of the main body portion and the plate surface of the connecting portion in the one terminal is a regular angle, the connecting portion and the main body portion are formed with an opening width that can be inserted. When the angles of the both plate surfaces are deviated from the regular angle, an opening is provided that interferes with the surrounding wall portion to restrict passage of the one terminal, and the other terminal has the above-mentioned A tubular coupling portion capable of receiving the joint portion of one of the terminals is provided, and an end portion of the joint portion on the side where the joint portion is inserted has a surface side intersecting with a plate surface of the joint portion. It is characterized in that a cutout portion is provided so that the connection portion can be received when the both terminals are connected by cutting out along the insertion direction of the joint portion.

According to a second aspect of the present invention, there is provided a valve socket provided with a socket main body in which a valve accommodating portion for mounting a valve and a connector accommodating portion for fitting a power supply side connector are provided at substantially right angles to each other. A valve including a valve terminal inserted into the socket main body from the valve housing portion side, and a connector terminal inserted into the socket main body from the connector housing portion side and connected to the valve terminal. A terminal for a socket, wherein one terminal of the two terminals is provided with a flat plate-shaped main body part, and a side plate provided on the main body part is bent so that the plate surface is a plate surface of the main body part. And a main body that is connected to the other terminal and is extended to the side of the joint so that the joint and the main body are connected to each other. And a connecting part having a connecting part for connecting the connecting part and a connecting part having a tubular shape capable of receiving the joint part of the one terminal, and the joint part of the joint part. At the end portion on the side where is inserted, a notch is formed along the insertion direction of the joint portion on the surface side that intersects the plate surface of the connection portion, so that the connection portion can be received when the terminals are connected. It is characterized in that a cutout portion is provided.

[0010]

According to the invention of claim 1, when one of the two terminals has a regular angle between the plate surface of the main body and the plate surface of the connecting portion. Only the opening can be inserted. Therefore, when the bending angle of the terminal is incorrect, the passage of the terminal is restricted by the opening, and the terminal cannot be inserted into the regular position in the housing portion. With this, it is possible to detect a defective bending angle when the terminal is attached. By the way, in view of the demand for miniaturization of the valve socket, the height of the insertion port of the terminal in the accommodating portion cannot be made higher than a certain level. Therefore, it is necessary to design the terminal according to the height of this insertion port, and the length of the joint portion of the terminal cannot be set to a certain length or longer. Therefore, the contact margin between the joint portion and the joint portion of the other terminal is reduced, which may make it difficult to secure the electrical connection between both terminals. In order to solve this problem, the joint portion may be deeply inserted into the joint portion of the other terminal, but the connecting portion connecting the joint portion and the main body portion is extended to the side of the joint portion. Then, the connecting portion is stuck at the insertion opening edge of the coupling portion, and the joint portion cannot be inserted further into the back. For this reason, a cutout portion is provided in the coupling portion of the other terminal,
At the time of connecting both terminals, the cutout portion can receive the connection portion of one terminal. With such a configuration, the joint can be inserted to the depth of the joint by the depth of the notch, and the contact area between the joint and the joint can be secured. As a result, the electrical connection between both terminals can be ensured.

According to the second aspect of the present invention, the connecting portion is formed on one of the terminals by bending the side plate provided on the main body portion in a direction intersecting the insertion direction of the terminal. By thus setting the bending angle so as to intersect with the insertion direction of the terminal, when the terminal is inserted into the accommodating portion of the valve socket, it is restricted by the angle between the plate surface of the main body and the plate surface of the connecting portion. It becomes possible. This makes it possible to detect a defective bending angle when the terminal is attached. Further, a cutout portion is provided in the coupling portion of the other terminal, and the connection portion can be received in this cutout portion when both terminals are connected. Therefore, the joint portion can be inserted to the depth of the connection portion by the depth of the notch portion, and the contact area between the joint portion and the connection portion can be secured.

Next, the connector terminal 3 will be described with reference to FIGS. The connector terminal 3 is provided with two connecting pieces 31 and 32 at both ends of a main body portion 35 formed of a conductive metal in a long plate shape (FIG. 6). One of the connecting pieces 31, 32 is formed by forming one end of the main body portion 35 into a tab shape, and is a connector connecting piece 31 that can be connected to the power supply side connector.

On the other hand, a terminal connecting piece 32 (corresponding to the connecting portion of the present invention) is formed on the other end side of the connector terminal 3. This terminal connecting piece is formed by bending a U-shaped side plate 36 (see FIG. 5) provided on the other end side of the connector terminal 3. The side plate 36 has a shape in which one end of the side plate 36 is connected to the end of the connector terminal 3 with the U-shaped opening side facing the width direction of the connector terminal 3. Then, at the base portion of the side plate 36, the width direction of the connector terminal 3 (the arrow direction in FIG. 5), that is, the direction intersecting the insertion direction D2 of the connector terminal 3 into the second terminal accommodating portion 25 (hereinafter , Bending direction D
(Referred to as “1”), the terminal connecting piece 32 connectable to the valve terminal 4 is formed.

In the connector terminal 3 thus formed, the U-shaped opening side is the upper side, the plate surface 32A of the terminal connecting piece 32 is in the vertical direction, and the plate surface 35A of the main body portion 35 is in the horizontal direction. In this state, it is attached to the second terminal accommodating portion 25 (FIGS. 6 to 8). One side of the terminal connecting piece 32 that is not connected to the main body portion 35 is a tab portion 32C (corresponding to the joint portion of the present invention), and the valve terminal 4 can be connected thereto. There is. Further, the remaining L-shaped portion is a connecting portion 32B that connects the tab portion 32C and the main body portion 35.

A front stop 33, which is slightly wider than the connector connecting piece 31, is formed at a position slightly closer to the terminal connecting piece 32 in the center of the main body 35. A pair of abutting protrusions 34 protruding laterally are provided at positions slightly closer to the terminal connecting pieces 32 than that. The contact protrusions 34 are slightly press-fitted into the left and right wall surfaces of the lateral hole portion 26B in the second terminal accommodating portion 25, so that the connector terminal 3 is retained and retained.

Next, the structure of the valve terminal 4 will be described with reference to FIGS. Valve terminal 4
Is formed by bending a conductive metal plate material, and is elastically contactable with each of the connector terminal 3 and the valve. The valve terminal 4 includes a substantially rectangular substrate portion 41 that is long in the up-down direction, a pair of upright portions 44 that are folded up from the left and right edges of the lower portion of the substrate portion 41 in a substantially perpendicular direction, and a lower portion of the substrate portion 41. And a coupling portion 46 formed on the side (FIG. 10).

From the vicinity of the upper edge of the base plate portion 41, a pair of left and right spreading pieces 42 are provided so as to project. Both of the expanding pieces 42 are obliquely bent in the direction in which the standing portion 44 is folded. Due to the bending, the expansion piece 4 is expanded from the substrate portion 41.
The thickness up to the tip position of 2 is slightly larger than the width of the groove portion 22A in the first terminal accommodating portion 22. Therefore, when the valve terminal 4 is accommodated in the first terminal accommodating portion 22 of the socket body 2, the tip end of the expanding piece 42 abuts on the inner surface side of the groove portion 22A, so that the valve terminal 4 in the thickness direction. Rattling is restricted. Further, in the base plate portion 41, below the both spreading pieces 42, the biting pieces 4 are formed.
3 is projected. Both biting pieces 43 bite slightly into the retaining wall surface 23 when the valve terminal 4 is pushed to a predetermined position with respect to the first terminal accommodating portion 22,
Prevent the valve terminal 4 from coming off.

Only the lower end side of the compatible mounting portion 44 is connected to the base plate portion 41 (see FIG. 11), and the upper side is formed as a free end, and a pair of valve contact pieces 45 for contacting the valve are provided. Has been done. The valve contact pieces 45 are smoothly bent in a direction closer to each other above the connecting portion, and the mountain-shaped contact portions 45A are provided at the closest portions, and then smoothly folded back in a direction away from each other. The ends are free ends facing in opposite directions (left and right in FIG. 10). Both valve contact piece 45
Can be flexibly deformed in a direction in which they approach or separate from each other, and can elastically contact the valve.

The connecting portion 46 is composed of an elastic contact piece 48 and a rectangular tube portion 47 that covers the elastic contact piece 48. In the rectangular tube portion 47, side wall portions 47B extend in the direction in which the standing portions 44 are folded up from the left and right sides of the rear wall portion 47A extending downward from the lower end edge of the base plate portion 41, and the side wall portion 47B. The ends of the front wall 47 are bent inward at right angles.

Further, the elastic contact piece 48 is formed by the lower end edge of the rear wall portion 47A protruding downward and then folded back inwardly in a mountain shape (FIG. 12). The tops of the peaks of the elastic contact pieces 48 are close to and face the front wall portion 47C to a distance smaller than the plate thickness of the connector terminal 3, and the elastic contact pieces 48 and the front wall portion 47C are opposed to each other. The tab portion 32C of the connector terminal 3 can be inserted into the gap.

Further, a cutout portion 49 is formed in the side wall portion 47B which is a surface which intersects the terminal connecting piece 32 when the connecting portion 46 is connected to the connector terminal 3. The cutout portion 49 is formed by cutting off a predetermined portion from the lower end portions of the both side wall portions 47B to slightly above the entire width (see FIG. 11), and the folded portion of the elastic contact piece 48 is slightly exposed. It is supposed to be done.

Next, the operation and effect of this embodiment configured as described above will be described with reference to FIGS.

First, the connector accommodating portion 2 of the socket body 2
Insert the pair of connector terminals 3 from the 4 side (FIG. 13,
(Fig. 14). Each connector terminal 3 is supported with the U-shaped opening of the terminal connecting piece 32 on the upper side, the plate surface 32A in the vertical direction, and the plate surface 35A of the main body 35 in the horizontal direction. Then, the terminal connecting piece 32 side is directed toward the valve accommodating portion 21, and the terminal connecting piece 32 is pushed into the second terminal accommodating portion 25 with the direction along the bent edge 32D as the insertion direction D2. At this time, in the connector terminal 3, if the plate surfaces 32A and 35A of the terminal connecting piece 32 have an angle R of substantially right angles, the terminal connecting piece 32 can pass through the vertical hole portion 26A and enter the inside. I will do it.

When the terminal connecting piece 32 is inserted all the way, the body portion 35 of the connector terminal 3 reaches the opening 26 of the second terminal accommodating portion 25. At this time, in the connector terminal 3, if the bending angle R of the terminal connecting piece 32 is substantially a right angle, the body portion 35 can enter the inside of the lateral hole portion 26B. The contact projections 34 contact both side wall surfaces to prevent the connector terminals 3 from coming off and to position them. Thus, in the socket body 2, the connector terminal 3 is set in a standby state inside the connector accommodating portion 24 with the tab portion 32C of the terminal connecting piece 32 standing upright (see FIG. 14). .

Next, the pair of valve terminals 4 is inserted from the valve accommodating portion 21 side. The terminals 4 for both valves are the substrate portion 4
1 in a parallel state, and are pushed in from the joint portion 46 side in a posture in which the standing portions 44 face each other (FIG. 15,
(Fig. 16).

With the insertion operation of the valve terminal 4,
The connection operation of both terminals 3 and 4 is performed. That is, the valve terminal 4 is provided on one side wall portion 47B of the rectangular tube portion 47.
While being inserted into the U-shaped opening of the terminal connecting piece 32 of the connector terminal 3, the terminal is pushed inward. Along with this, the tab portion 32C of the connector terminal 3 in the standby state comes into the gap between the elastic contact piece 48 and the front wall portion 47C.

When the valve terminal 4 is pushed to a predetermined position, the bottom portion of the connecting portion 32B of the terminal connecting piece 32 enters the cutout portion 49 of the rectangular tube portion 47, and the upper end of the cutout portion 49 is connected. It is brought into a state of hitting the portion 32B (FIG. 17). In this state, the tab portion 32 of the terminal connecting piece 32
C is accommodated in the gap between the elastic contact piece 48 and the front wall portion 47C, and the elastic restoring force of the elastic contact piece 48 causes the front wall portion 47C
Elastically adheres to. As a result, both terminals 3 and 4 are electrically connected. At this time, the tab portion 32C can be inserted into the rectangular tubular portion 47 by the depth of the notch portion 49, so that the contact area between the tab portion 32C and the elastic contact piece 48 is secured, and both terminals 3, The electrical connection of 4 can be ensured.

After the assembly of the valve socket 1 is completed in this way, the valve is fitted in the valve housing 21 and the power supply side connector is fitted in the connector housing 24.

Now, in the connector terminal 3, the bending angle of the terminal connecting piece 32 may be incorrect. Here, the terminal connecting piece 32 is formed by bending the side plate 36 in a direction (bending direction D1) that intersects the insertion direction D2 of the connector terminal 3 into the second terminal accommodating portion 25, and Plate surface 32A and body 3
The plate surface 35A of No. 5 intersects with the plate surface 35A. Therefore, if the connector connecting piece 31 is aligned with the lateral hole portion 26B, that is, the connector terminal 3 is held and inserted into the opening 26 so that the connector connecting piece 31 is substantially horizontal, the terminal connecting piece 31 is connected. Piece 32 is vertical hole 2
6A will be inclined (see FIG. 19). The vertical hole portion 26A is formed with an opening width that allows the connector terminal 3 to be tightly inserted. For this reason,
The terminal connecting piece 32 in an oblique posture is caught by the wall portion 26C around the vertical hole portion 26A and cannot pass through the inside thereof. On the other hand, if the terminal connecting piece 32 is aligned with the vertical hole portion 26A, that is, the terminal connecting piece 32 is to be inserted into the opening portion 26 so as to be substantially vertical, the connector connecting piece 31 will have the horizontal hole portion 26B. You will incline at an angle. The lateral hole portion 26B is formed with an opening width that allows the connector connecting piece 31 of the connector terminal 3 to be tightly inserted. Therefore, the connector connecting piece 31 that is inclined is caught by the wall portion 26C around the lateral hole portion 26B and cannot enter the inside thereof. This makes it possible to detect a defect in the bending angle of the connector terminal 3.

The technical scope of the present invention is not limited to the above-described embodiment, and the following technical scope is also included in the technical scope of the present invention. In addition, the technical scope of the present invention extends to an equivalent range.

(1) In the above embodiment, the connector terminal 3
The valve terminal 4 is inserted later after being put in the standby state. However, according to the present invention, even if the valve terminal is put in the standby state and the connector terminal is inserted later. Good.

(2) In the above embodiment, the connector terminal 3
Although the terminal connecting piece 32 that is a connecting portion is provided on the side and the square tube portion 47 that is a connecting portion is provided on the valve terminal 4 side, according to the present invention, the connecting portion is provided on the valve terminal side. A coupling portion may be provided on the connector terminal side.
