DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an outlet with a multi-socket switch which does not require soldering.

[0002]

2. Description of the Related Art An outlet structure with a multi-socket switch is currently applied to electrical products such as an extension cord outlet and a multi-conversion outlet. It is mainly
As shown in FIG. 9, a plurality of sets of socket cases A1 are installed on the outlet A, and a set of push-type switch cases A2 is installed on one side of each socket case A1. There are various types of push-type switch cases A2, such as a type equipped with a pilot lamp inside the switch, or a type in which the switch itself also has a load protection function and automatically cuts off electricity when overloaded. Control the conductivity of the socket case.

As shown in FIG. 10, the first energizing line contacts A21 of the respective switch cases A2 are mutually pierced by a copper wire A6 and jointly connected to a terminal A31 of a load protector A3. This is because each set of switch cases A2 has no load protection function. The other terminal A32 of the load protector A3 is connected to an energizing line of an external power supply. The energizing wire contacts A22 of the switch case A2 are connected to independent copper wires A5, respectively.
As a result, it is connected to the conductive contact A11 of the socket case A1.

[0004] Each of the switch cases A2 in the second and subsequent rows is used.
Are connected to the conductive contacts A12 of the socket case A1 by independent copper wires A41. Also, the ground contact A23 of the switch case A2 in the first row
Is connected to the conductive contact A12 of each socket case A1 by a copper wire A4, and the copper wire A4 is connected to the ground of the external power supply.

In the structure of the outlet A, whether or not each socket case A1 on the outlet A is conductive is controlled by switching the corresponding switch case A2. Therefore, the conductive contacts A11 and A12 in each socket case A1 are used to securely connect each contact.
And the first and second conducting wire contacts A21 of the switch case A2,
Soldering is required for all A22 and ground contact A23.

[0006]

However, since the soldering is a manual operation, the quality of the soldering is greatly influenced by the skill of the workers, and there is a possibility that the solder material may be excessive or insufficient. This is a serious problem that affects quality. Furthermore, if the amount of the solder material is excessive, a leakage phenomenon of the solder material occurs, which causes malfunctions of peripheral electronic components, thereby greatly increasing the defective product rate. On the other hand, if the solder material is not sufficient, the contact is likely to cause poor contact.

[0007] In addition, when the main power supply of the outlet is turned off, it is necessary to press a switch of the outlet one by one. Thus, all sockets can be turned off for the first time. However, this is very cumbersome to use and a waste of time.

Accordingly, an object of the present invention is to provide a structure of an outlet with a multi-socket switch which does not require soldering in order to solve the above-mentioned drawbacks. Another object of the present invention is to provide a structure of an outlet with a multi-socket switch that can easily shut off power.

[0009]

In order to solve the above-mentioned problems, the present invention provides a multi-socket switch by installing each switch unit in a switch case, and at least two or more sets of installation tanks on the switch case. And a switch unit and at least two conductive pieces are respectively installed in the installation tank. The switch unit in the installation tank controls conduction and cutoff between the conductive pieces in the tank, and a switch in the installation tank. The conductive pieces extend the holding pieces corresponding to the respective sockets, and the holding pieces have a structure of an outlet with a multi-socket switch serving as a current-carrying contact of a plug insertion portion.

Another invention is a multi-socket switch in which a grounding conductive piece in an installation tank corresponds to each socket and extends another holding piece, and each holding piece serves as a ground contact of a plug insertion portion. The outlet has a structure.

In another aspect of the present invention, an outlet with a multi-socket switch is formed by molding a holding piece into a contact piece.

Another aspect of the present invention relates to a socket with a multi-socket switch, in which each of the sockets corresponding to the switch unit has a ground contact at the plug insertion portion formed separately from the socket outside the switch case. I am trying to do it.

According to another aspect of the present invention, a transition plate is installed in a switch case, the transition plate is positioned horizontally between a plurality of switch components, and a pushing block is installed at an interval between the transition plates. Is an open space, a specific switch component of a plurality of switch components is installed in the switch case, and the transition plate is linked, and when any switch component other than the specific switch is energized, the arbitrary switch component operates. Then, the corresponding push block is pushed, and the transition plate is turned on in conjunction with the specific switch component.On the other hand, when the specific switch component is turned off, the push block of the transition plate is already turned on at the same time. The socket has a structure with a multi-socket switch that is turned off by pressing any switch component.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the first embodiment of the structure of the outlet with the multi-socket switch mainly comprises:
Switch case 1, switch unit 2, conductive piece 3,
4 and 5. Switch case 1 is base tank 1
1 and the bottom cover 12 or are formed by directly molding a base having an open shape on one side. Base tank 11
The inside is partitioned and has at least one or more set tanks 111. The installation tank 111 is used for installing the switch unit 2.

The switch unit 2 has a switch-type or push-type switch component 21 installed therein.
Here, a push-type switch structure will be described as an example. The switch component 21 has a pilot lamp installed therein, and a resilient and conductive center pillar 211 installed at the bottom. The opposite end of the center column 211 is connected to a pilot lamp inside the switch component 21. The center column 211 is used for switching a bullet 212 in the switch case 1 described later.

In the switch case 1, a first conductive piece 3,
The second conductive piece 4 and the third conductive piece 5 are provided. The third conductive piece 5 belongs to the ground conductive piece, is an integral piece, and is also a ground circuit of a pilot lamp installed in the switch component 21. When the pilot lamp is not installed in the switch component 21, the third conductive piece 5 becomes unnecessary. Inside the third conductive piece 5, the third contact piece 51 extends inward and is used for fitting the spring 23 of the switch unit 2. The other end of the spring 23 is connected to a pilot lamp installed in the switch component 21 to form a circuit.

The first conductive piece 3 belongs to a conductive wire conductive piece, is an integral piece, and is connected to a conductive line of an external power supply to form a conductive line input route. The first conductive piece 3 has a first contact piece 31 corresponding to the number of the switch components 21 and extending horizontally and having contacts. Each first contact piece 31 is attached to each installation tank 11.
Stretch into 1. The second conductive piece 4 belongs to another conductive piece and serves as an energization line output route. The second conductive piece 4 is an independent type piece, and each piece is stretched corresponding to each installation tank 111,
The second contact piece 41 is formed in each installation tank 111.
A cutout 411 is provided at the end of the second conductive piece 4, and is used for fitting the elastic piece 212 of the switch component 21. The bullet 212 can switch between contact and detachment at the first contact piece 31.

Thus, the first conductive piece 3 and the second conductive piece 4
(I.e., control of conduction or disconnection between the conduction line routes). In addition, the second conductive piece 4 and the third conductive piece 5 each include a second holding piece 42 and a third holding piece 52 that extend outward and come into contact with the insertion portion of the plug. Second holding piece 42
Is a conductive piece in the outlet, and the third holding piece 52 is a ground conductive piece in the outlet. The second sandwiching piece 42 and the third sandwiching piece 52 correspond to the thickness of the plug insertion portion, are formed into a U-shaped cross-section by bending, and are suitable for holding the plug insertion portion.
The second holding piece 42 and the third holding piece 52 may be formed into a single-piece contact piece shape or another shape as long as they can be stably contacted with the plug insertion portion in addition to the U-shaped cross-sectional shape. Can also.

After the combination of the above structures, as shown in FIG. 2, a multi-socket switch structure having a large number of switch units 2 and requiring no soldering is formed. The conducting wire conductive piece and the ground conductive piece (the second conductive piece 4 and the third conductive piece 5 in the above example) in each of the switch units 2.
Directly extend a pair of conductive holding pieces (in the above example, the second holding piece 42 and the third holding piece 52). Each set of conductive clamps can form a conductive line contact point and a ground contact point in a set of outlets. This allows
No soldering is required between each set of switch units 2 and each set of outlets. The multi-socket switch structure also includes a one-to-one multi-socket outlet structure.

Next, as shown in FIG. 3, the first, second, and third conductive pieces 3, 4, and 5 are connected to the switch case 1 by first, second, and third contact pieces 31, 41, and 51, respectively. Are extended and installed in each of the installation tanks 111 to form three contacts of the switch unit 2. The switch component 21 has a central pillar 21 at the bottom.
The switch 1 switches the bullet 212 to control the contact or detachment between the bullet 212 and the first contact piece 31, and further controls the conduction or disconnection of the power supply line in each switch unit 2.

As shown in FIG. 4, the second holding piece 42 and the third holding piece 52 are installed in parallel on the outer base surface of the switch case 1, and each set of the second holding piece 42 and the third holding piece 5
2 are located below the socket of each outlet 6 respectively. Thus, when the plug insertion portion is inserted into the socket, the second holding piece 42 and the third holding piece 52 come into direct contact.
Further, the switching of each switch component 21 can control the energization and cutoff of each outlet 6.

The first conductive piece 3 and the third conductive piece 5 of the "integrated switch structure" assembled by the above-described method are both continuous pieces. For this reason, in one assembly work,
The assembly of the first contact piece 31 and the third contact piece 51 in each installation tank 111 is completed at the same time, and the conductive contacts in the switch unit 2 are formed in each installation tank 111.

In addition, because of the continuous one piece structure, the soldering work of the first contact piece 31 and the third contact piece 51, which is conventionally required, can be omitted completely. In particular, the second holding piece 42 and the third holding piece 52 from which the second conductive piece 4 and the third conductive piece 5 extend are installed directly on the socket bottom of the outlet 6 and form contact with the outlet 6.

With such an integrated structure design, all the switch units 2 do not need to be soldered separately from the circumscribing outlet, and the soldering of the contacts becomes completely unnecessary. In this way, the assembly process of the outlet with the multi-socket switch can be made precise,
It is possible to eradicate the bad effect of the soldering contact failure.

Next, as shown in FIG. 5, in the case where the pilot lamp is not installed in the switch unit 2, each installation tank 111 of the switch case 1 has only two contacts. One of them is constituted by the first contact piece 31 of the first conductive piece 3 (that is, the conducting wire output end), and the other is constituted by the second contact piece 41 of the second conductive piece 4 ( That is, the conducting wire input end). The connection between the two contact points is switched by a bullet 212. The third conductive piece 5 in the above example is not installed.

In the second embodiment, all of the second conductive pieces 4 of the switch case 1 directly extend the second holding piece 42 uniformly, and form a current line contact point of the outlet 6. All the ground contact points of the outlet 6 are in the form of a single piece, and serve as the ground conductive pieces 9 of the outlet 6.
The grounding conductive pieces 9 extend from the holding pieces 91 so as to correspond to the respective outlets 6. The respective holding pieces 91 and the second holding pieces 42 from which the second conductive pieces 4 extend form jointly the contact points of the sockets of the respective outlets 6. Thus, the same effect as in the above structure is provided.

Also, as shown in FIG. 6, the present invention can be implemented in other forms utilizing similar structures. The third embodiment uses a specific switch component 21 'and has a function of a main power supply for the entire switch. In this structure, the transition plate 7 is mainly installed horizontally in the switch case 1 and extends between the switch parts 21. The transition plates 7 are spaced apart and some pushing blocks 72 are installed. One side of each pushing block 72 is an open space 71 and a perforation 73 is formed at the end of the transition plate 7. At the end of the switch case 1, a support base 8 corresponding to the perforation 73 and having a cutout 81 at the apex is installed.

At the time of assembly, the specific switch component 2
The column part 22 ′ extending to the bottom of 1 ′ extends into the perforation 73 of the transition plate 7, and its advance / retreat is controlled by interlocking with the transition plate 7. FIG. 7 shows a state after the assembly of the third embodiment. In FIG. 7, the switch components 21 are all in the closed state.

Next, as shown in FIG. 8, when an arbitrary set of switch parts 21 is pressed and energized, the column parts 22 of the switch parts 21 push the pushing blocks 72 of the transition plate 7. As a result, the perforation 73 at the end of the transition plate 7 pushes the specific switch component 21 'to turn it on. At this time, the pilot lamp in the specific switch component 21 'is turned on. At this stage, the pillar component 2 of any switch component 21
2 is free to be active in the open space 71 of the transition plate 7. Therefore, the pressed arbitrary switch component 21 is
It does not affect the ON state of the specific switch component 21 '. However, when the specific switch component 21 'is pressed to turn off the power, the column component 22 pushes the transition plate 7 and moves it in the lateral direction. Then, each pushing block 72 of the transition plate 7 pushes the column component 22 of each switch component 21 that has already been turned on. As a result, each switch component 21 already turned on
Are all turned off at the same time.

Further, the specific switch component 21 'is directly molded at the end of the transition plate 7 so that the movement of the transition plate 7 can be directly controlled. Alternatively, using a switch component having another different configuration, the transition plate 7 is urged to move in the lateral direction, and the pushing block 72 of the transition plate 7 directly pushes the column component 22 of each switch component 21. Thus, it is also possible to turn off all the switch components 21 at the same time.

In addition, each switch unit 2 on the switch case 1 has another function, and a fourth (or more) conductive piece can be provided as necessary. In this case, the function of the fourth (or even more) conductive piece can be “integrated piece” or “independent piece” depending on the individual situation.

[0033]

According to the structure of the outlet with the multi-socket switch according to the present invention, the work of soldering between the switch of the outlet with the multi-socket switch and the outlet can be completely eliminated, and the construction period and process can be reduced. Can be shortened. As a result, it is possible to improve the assembling speed, eradicate the state of poor contact caused by the manual soldering operation, and reduce the defective product rate. In addition, since the power supply can be easily shut off, the usability is excellent.
