Description

  The present invention relates to a rocking structure of a power connection terminal, and in particular, a rocking structure in which the direction of the plug blade can be changed up and down to conveniently adjust the arrangement direction of the accompanying cord. By forming a multi-sided contact connection with multiple layers of two ears in position, electricity can flow through a wide path, avoiding temperature rises and swinging smoothly, making the power connection terminal swing. It relates to a moving structure.

  In some cases, the power is drawn from the wall outlet of the building or the outlet of the extension cord, but this method inserts the plug blade installed in the power plug into the outlet of the above outlet and contacts the electrode. Letting out electrical energy.

  Among them, the wall outlet of the building is installed in a certain direction, and the outlet of the extension cord is a free body, but since it is shared with multiple plugs, it is not easy to change considering the angle, and other common It is necessary not to affect the plug connection direction. Depending on the arrangement direction of the cord, the connection part of the power cord and the plug is often restricted in the direction of the outlet, causing twisting, and this twisting causes thermal decomposition of the metal structure of the inner conductor, and the effect of temperature rise due to Joule heat Is generated.

  In view of the limitations of the above conditions, there is an F-shaped design in which the plug blade of the power plug and the cord body are perpendicular to make the arrangement angle between the power plug and the power cord adaptively changeable. Since the cord body hangs vertically due to the action of gravity after insertion, it prevents the cord from bending and splitting into the metal structure of the cord, keeps the current flowing smoothly, and the cord protrudes from the wall after insertion It is possible to prevent damage due to external force by reducing the height to be attached and allowing the accompanying cord to stick to the wall surface.

  The above-mentioned F-shaped design solves the problem of protruding from the wall surface, but the insertion direction is fixed in one direction, and when it is plugged into an outlet on a horizontal plane, the arrangement of cords in one direction is restricted In the case where the polarity directions of the live wire and the ground wire are limited, it is difficult to apply the multi-directional arrangement, and therefore there is a design that can swing the plug blade, for example, Taiwan Patent Publication No. 568433, There are prior designs such as No. M245653 and No. M250417, but there is provided a plug blade capable of effectively swinging the vertical angle within the range of angles included in the two quadrants.

  Similar products sold in the market with the above-mentioned pre-designs are relatively weak in their pivoting and conduction mechanism, so the current is subjected to resistance, resulting in Joule heat, and the temperature of the plug rises, generally The temperature rise reaches 26 to 32 ° C., and the environmental temperature is added to this.

  The various designs described above only pivot on one side of the two flat plates between the blade and the connection terminal, i.e., the power connection relationship between the blade and the connection terminal is a single surface contact, In addition, sufficient contact is finally obtained by pressing the rivet, and when the contact surface being pressed rotates several times around the rivet as the axis, surface friction is generated and the thickness is worn. Since the contact force between the plug blade and the connection terminal is lost when the pressure contact surfaces of the opposing terminal surfaces are worn, a plug with the function of swinging the plug blade often has an immediate effect of increasing the temperature. Since it is formed by resistance, it is a great harm to power transmission.

  The detailed structure and operation of the present invention will be described below with reference to the drawings. First, as shown in FIGS. 1 and 2, the power plug 1 of the present invention has a power feeding member 10 connected to the rear end, and the power feeding member 10 is supported and connected by an insulating seat body 5. The plug blade 2 is pivotally attached to the connection terminal 3, and the two plug blades 2 are installed in parallel, and can swing up and down within the range of possible rotation angle Y. The two plug blades 2 are connected via an insulating rotating body 4, and the insulating rotating body 4 swings in synchronization with the plug blade 2 and achieves power insulation protection and positioning support functions. The moving body 4 moves relative to the insulating seat body 5, and the insulating seat body 5 is subjected to an operation of grasping with a hand when the plug is inserted or removed, and the one end of the connection terminal 3 and the power supply member 10 (electric cord) are electrically connected. To achieve.

  Among them, the axial connection between the connection terminal 3 and the plug blade 2 and the structural relationship of the power supply member 10 connected to the rear end of the connection terminal 3 are as shown in FIGS. 3 and 4 at the rear end of the connection terminal 3. A pressure contact end 32 is formed, a cord tip of a conductive end of the power supply member 10 is coupled to the pressure contact end 32, and a hinge seat portion 31 is provided at the other end of the connection terminal 3, and the hinge seat portion 31 is a first hinge portion 311. And the second hinge portion 312 are provided in parallel with each other to constitute two ear portions, and a shaft hole 310 is formed in a penetrating manner at the center of the surface. The stopper blade 2 is provided with a shaft attachment portion 21 at one end opposite to the hinge seat portion 31, and a shaft hole 210 is opened at the center of the surface. After the shaft hole 310 and the shaft hole 210 are overlapped, the rotation shaft 6 is moved. The shaft attaching portion 21 of the plug blade 2 is attached to the hinge seat portion 31, that is, held while the two surfaces of the shaft attaching portion 21 face the second hinge portion 312 and the first hinge portion 311. The four-layer surface contact is formed, and the current of the power source is transmitted from the second hinge portion 312 or (and) the first hinge portion 311 to the press contact end 32 by the contact of the multiple layer surfaces, The effect of the gap resistance is greatly reduced, and the mechanical frictional resistance is dispersed or the resistance stress is absorbed at the time of swinging of the blade 2 due to the multilayered relationship. The power becomes smoother.

  In addition, the relative positional relationship between the second hinge portion 312 and the first hinge portion 311 of the hinge seat portion 31 is set to a relative position quasi-coordinate, and the face distance of the original is smaller than the thickness value of the shaft attachment portion 21. In addition, since an elastic stress exists between the second hinge portion 312 and the first hinge portion 311, an elastic force that is sandwiched and pressed after the shaft attachment portion 21 is installed is generated, and the second hinge portion 312 and the first hinge portion are generated. A clear stress is obtained in which 311 is opposed to both side surfaces of the shaft attachment portion 21 and is in close contact with each other, and the contact force required on both sides of the second hinge portion 312, the first hinge portion 311 and the shaft attachment portion 21 is obtained by this stress. And the current can be ensured to flow smoothly between them. The above-described elastic stress is obtained from selection of a material at the time of manufacturing the connection terminal 3.

  Among them, the second hinge part 312 is continuously connected as a single unit with the first hinge part 311, that is, the second hinge part 312 is continuously bent as a single unit from the connection terminal 3, and the first hinge part 311 is formed. And the second hinge part 312 are connected as a single unit, and further provided with a pressure contact 30, and the plate-like part extending from the second hinge part 312 and the plate-like part of the connection terminal 3 main body are coupled by mechanical pressure.

Since the hinge seat portion 31 formed by 311 has an elastic force, after the stopper blade 2 is axially attached, pressure contact is formed elastically on the left and right surfaces of the axial attachment portion 21, thereby connecting terminals. 3 can be effectively transmitted to the blade 2. Further, by inserting the rotating shaft 6, the plug blade 2 can be completely attached to the hinge seat 31.

Similarly, it is possible to achieve the axial attachment by acting on the shaft hole 210, and the use of the rotating shaft 6 may be substituted at this convex point. The connection between the pressure contact end 32 and the power supply member 10 is mainly performed by wrapping the cord tip 100 provided on the power supply member 10 using an arc portion of the pressure contact end 32, or by a welding method or an arbitrary screwing method.

The second hinge part 312 may be pressure-bonded by using it, and an auxiliary elastic pressure-bonding may be obtained between the second hinge part 312 and the first hinge part 311. After the rotation shaft 6 is penetrated through the hinge seat portion 31, the end thereof can be processed and locked to the opposite side surface of the first hinge portion 311 so that the elastic acting force of the elastic packing 7 is applied to the second hinge. It can be ensured that it acts between the part 312 and the first hinge part 311.

  As for the support method in which the plug blade 2 and the connection terminal 3 are mechanically positioned, as shown in FIG. 5, the plug blade 2 is pivotally attached to the connection terminal 3, and the connection terminal 3 depends on the internal structure of the insulating seat body 5. Since the power supply member 10 is connected to the rear end and the insulating seat body 5 is an insulator, it can be insulated from the connection terminal 3 and can be gripped by a hand during the insertion / removal operation.
