Detailed ways

Below in conjunction with the accompanying drawings, first the embodiment of the first electrode clip of the present invention is described in further detail:

As shown in Figures 1-4, the electrode clip includes a connecting piece 1, a pair of main clips 2 are arranged on the two sides corresponding to the connecting piece 1, and a pair of auxiliary clips are arranged on the other two sides of the connecting piece 1 Pieces 3, a pair of main clips 2 and a pair of auxiliary clips 3 are located on the same side of the board surface of the connecting piece 1, and form an integral structure.

As shown in FIG. 9 , the two-pin plug 22 includes two electrical pins 23 . The electrical pins 23 are made of copper plate and have a rectangular cross-section, a width of about 6 mm, and a thickness of about 1 mm. Each electrical pin 23 has two inner and outer contact surfaces 24, and two sides 25 of the two contact surfaces 24 are provided on both sides. A pair of main clips 2 can be used to clamp on the inner and outer contact surfaces 24 of the electrical pins 23 to realize electrical connection. Since the surface areas of the inner and outer contact surfaces 24 are larger than the surface areas of the two side surfaces 25, the current passing through the contact surfaces is relatively larger, therefore, the main clip 2 becomes the main electrical contact. A pair of auxiliary clips 3 are used to clamp the two side surfaces 25 of the electrical pins 23 of the plug 22. Since the surface areas of the two side surfaces 25 of the electrical pins 23 are small, the current passing through the contact surfaces is relatively small. Therefore, the auxiliary clips Sheet 3 becomes an auxiliary electrical contact sheet. When used in a socket, the auxiliary clip 3 can be used as a moving contact piece of a switch in addition to being used for electrical connection. Compared with the prior art, the connecting piece 1 , the main clip 2 and the auxiliary clip 3 of the electrode clip are stamped and formed from a piece of copper, and there is no contact resistance between the three, so it is not suitable for burning.

The connecting piece 1 is provided with a through hole 4 for the electric pin 23 of the plug 22 to enter.

When the through hole 4 is disposed on the inner side of the corresponding jack 9, the electrical pins 23 of the plug 22 first enter the through hole 4 through the jack 9 during the insertion process, and then are inserted into the main clip 2 and the auxiliary clip 3 in the open mouth to form an electrical connection. Only when the electrical pins 23 are in contact with the main clip 2 or the auxiliary clip 3, can power on If the length is short, the chances of fingers touching the electrical pins 23 are smaller, and the risk of electric shock is smaller. In this way, the safety of the plug 22 during plugging and unplugging can be greatly improved.

The side of the connecting piece 1 is provided with a fixing piece 5 . Two fixing pieces 5 are respectively provided on both sides of each main clip 2 .

On the one hand, the fixing piece 5 can firmly fix the electrode clip on the shell of the socket. Its function is to fix the connecting piece 1 on the housing of the socket, and at the same time allow the main clip 2 and the auxiliary clip 3 to elastically deform on the connecting piece 1 to form a clamping force. Although the embodiment is designed for the electrical pin 23 of the plug to be a flat structure, the same applies to the electrical pin 23 having a cylindrical structure. . The opening angle of the main clip 2 is slightly larger than that of the electric pin 23 having a flat structure. The opening angle of the auxiliary clip 3 is smaller than that of the electric pin 23 having a flat structure.

Based on a general inventive concept, the second embodiment of the electrode clip of the present invention is further described in detail:

As shown in Figures 5-8, the electrode clip includes a connecting piece 1, a pair of main clips 2 are arranged on two sides corresponding to the connecting piece 1, and a pair of auxiliary clips are arranged on the other two sides of the connecting piece 1 Piece 3, a pair of main clips 2 and a pair of auxiliary clips 3 are respectively located on the front and back sides of the board surface of the connecting piece 1, and are in an integrated structure, and the connecting piece 1 is provided with a through hole for the plug 22 and the electrical pin 23 to enter. 4.

The main clip 2 and the auxiliary clip 3 can respectively clamp the electrical pins 23 of the plug 22 on both sides of the connecting piece 1 to achieve first and last contact. When used in a socket, the auxiliary clip 3 can be used as a moving contact piece of a switch in addition to being used for electrical connection. Usually, the main clip 2 is arranged near the jack 9 on the socket, and the auxiliary clip 3 is arranged near the bottom of the socket. The main clip 2 and the auxiliary clip 3 of the electrode clip are not electrified themselves, and only the auxiliary clip 3 is electrified after acting as the moving contact piece of the switch. The auxiliary clip 3 is located at a position close to the bottom of the socket, so that the electrical pins 23 of the plug 22 can be touched only when they enter a deeper position. Therefore, the parts where the electrical pins 23 of the plug 22 are exposed outside the socket can be greatly reduced. Minimize the risk of electric shock from fingers touching the pins.

Similarly, the side of the connecting piece 1 is provided with a fixing piece 5 . The main clip 2 is provided with a notch 6 near the root, and the fixing piece 5 is arranged on the outer side corresponding to the notch 6 . The notch 6 is set at the root of the main clip 2, that is, sacrificing some width space of the main clip 2, so that the root of the main clip 2 can be appropriately narrowed, so as to generate better elasticity without affecting its overcurrent. During manufacture, it can be formed by stamping at one time, that is, the fixing piece 5 can be formed by using the copper sheet at the notch 6, which is convenient for manufacture.

Based on a general inventive concept, the embodiment of the socket using the above-mentioned first electrode clip in the present invention will be described in further detail below:

As shown in FIG. 9 , the plug 22 is provided with a pair of electrical pins 23, which can be used together with the socket. The specific structure of the socket is shown in Figures 10-11, which includes a casing 8, a pair of sockets 9 are arranged on the casing 8, and a pair of electrode clips 10 as described above are arranged in the casing 8. As shown in FIG. 10 , the two electrode clips 10 are rotated 180 degrees in the direction indicated by the arrow. At this time, the openings of the pair of auxiliary clips 3 are facing upward and outward, and they are respectively provided in the pair of sockets 9 . The inner position of the connecting piece 1 is set close to the bottom position in the casing 8 .

The housing 8 is injection-molded from plastic. The housing 8 is provided with a pair of sockets 9 into which the electrical pins 23 of the plug 22 enter. When the electrical pins 23 of the plug 22 are inserted into the jacks 9 , the openings of the pair of main clips 2 and the pair of auxiliary clips 3 will be opened respectively, so that the pair of main clips 2 will be clamped inside and outside of one electrical pin 23 . On the two contact surfaces 24 , a pair of auxiliary clips 3 are clipped on the two side surfaces 25 of the electrical pin 23 to form an electrical connection. Since the pair of main clips 2 , the pair of auxiliary clips 3 and the connecting piece 1 are integral structures, not only there is no contact resistance inside, but the roots of the pair of main clips 2 and the pair of auxiliary clips 3 are longer than the connecting piece 1 It also has good elasticity and has up to four contact points with the electrical pins 23 of the plug 22. Compared with the prior art, the electrode clip 10 and the electrical pins 23 have larger contact points. The contact area not only has good electrical contact, but also has a small total contact resistance. When energized, the contact part is not easy to heat up. When plugging and unplugging, the formed electric spark will be dispersed, which can effectively avoid the burning of the contact part. The main clip 2 and the auxiliary clip 3 are clamped on the electrical pins 23 of the plug 22 from four sides to form four contact points, which can generate a large clamping force on the plug 22, so as to achieve the clamping force of the socket to the plug 22. lifting weight requirements.

If the conductive sheet 19 and the insulating sheet or insulating layer 20 in Figures 10 and 11 are removed, the internal structure of the electrode clip 10, the live wire conductive sheet 16 and the neutral wire conductive sheet 17 inside the casing 8 is as shown in Figure 12. . It can be seen from FIG. 12 that a live wire conductive sheet 16 and a neutral wire conductive sheet 17 are respectively provided on the outer side of one auxiliary clip 3 of each electrode clip 10, and an auxiliary clip 3 of the electrode clip 10 and the live wire conductive sheet are respectively provided. A disconnection interval 18 is respectively provided between 16 and the neutral conductor sheet 17 to form a normally open switch. When the electrical pins 23 of the plug 22 are inserted in the direction of arrow F, the electrical pins 23 can drive the auxiliary clips 3 to move in the direction of arrow M, and the disconnection interval 18 is gradually reduced until the auxiliary clips on the pair of electrode clips 10 are The sheet 3 is in contact with the live wire conductive sheet 16 and the neutral wire conductive sheet 17 respectively to form the switch closed state.

Due to the existence of the disconnection interval 18 , before the plug 22 is inserted into the socket, the pair of electrode clips 10 and the live conductor sheet 16 and the neutral conductor sheet 17 are in a disconnected state. Any one of the electrode clips 10 in the pair of electrode clips 10 is not electrified, therefore, the user's finger will not get an electric shock when touching any one of the electrode clips 10 . When the plug 22 is inserted into the socket, the electrical pins 23 drive the auxiliary clips 3 to move toward the disconnection interval 18 . The two electrode clips 10 are respectively contacted with the live wire 16 and the neutral wire 17. At this time, a pair of electrode clips 10 are respectively connected to the live wire and the neutral wire through the live wire 16 and the neutral wire 17. The dimensions of the two electrode clips 10 are the same, and the dimensions of the live wire conductive sheet 16 and the neutral wire conductive sheet 17 are also the same. The live wire conductive sheet 16 and the neutral wire conductive sheet 17 in FIG. Less, easy to install, the cost can be greatly reduced.

On the basis of the socket with the above structure, there are still two sockets with different functional structures. The specific examples are as follows:

The first sockets with different functions are:

The housing 8 is provided with two conductive sheets 19, each conductive sheet 19 is provided with two electrical contact portions 21, an electrical contact portion 21 of each conductive sheet 19 and an auxiliary clip 3 of each electrode clip 10 Opposite to each other with a disconnection space 18 therebetween, another electrical contact portion 21 of each conductive sheet 19 and another auxiliary clip 3 of each electrode clip 10 are arranged opposite to each other, with an insulating sheet or The insulating layer 20, the back of the other electrical contact portion 21 of each conductive sheet 19 is respectively provided with the live wire conductive sheet 16 and the neutral wire conductive sheet 17, and the other electrical contact portion 21 of each conductive sheet 19 is connected with the live wire conductive sheet 16 and the neutral wire conductive sheet 17 respectively. A disconnection interval 18 is provided between the neutral conductor sheets 17 .

When an electrical pin 23 of the plug 22, or a metal piece, or a screwdriver bit is inserted into the socket 9, the two auxiliary clips 3 on the corresponding electrode clips 10 are opened to both sides in the socket 9. , or one of the auxiliary clips 3 is opened to one side, at this time, the two auxiliary clips 3 on the electrode clip 10 have the following two states: 1. One of the auxiliary clips 3 on one side and the conductive strip 19 An electrical contact portion 21 contacts, enabling a switch K1-1 on the first path to be turned on. 2. The auxiliary clip 3 on the other side drives the insulating sheet or the insulating layer 20 to make the electrical contact portion 21 of the other conductive sheet 19 contact the live wire conductive sheet 16 or the neutral wire conductive sheet 17 to realize a switch on the second circuit K1-2 is turned on, that is, two auxiliary clips 3 on one electrode clip 10 can simultaneously control the on-off of two switches K1-1 and switch K1-2. Similarly, the two auxiliary clips 3 on the other electrode clip 10 can also control the on-off of the two switches K2-1 and K2-2 at the same time. The circuit composed of two electrode clips 10 and four switches K1-1, switch K1-2, switch K2-1 and switch K2-2 is shown in FIG. 13 .

It can be seen that this structure forms a safety protection circuit, that is, two switches connected in series are formed between each electrode clip 10 to the live wire conductive sheet 16 or the neutral wire conductive sheet 17, a total of two switches and four switches. The on-off of the two series switches on each circuit is controlled by the actions of the auxiliary clips 3 on the two electrode clips 10 respectively.

Before the plug 22 is inserted into the socket, the two electrode clips 10 are in a disconnected state with the live wire conductive sheet 16 and the neutral wire conductive sheet 17 . Therefore, none of the electrode clips 10 is electrified, and any electrode clips 10 will not be electrocuted when the user's finger touches any of the electrode clips 10 . When a metal piece is inserted into one of the sockets 9 in the socket, the corresponding electrode clip 10 in the socket 9 is pulled by the metal piece, causing the auxiliary clip 3 on the electrode clip 10 to act, and the two In the road, only one switch can be turned on on one of the routes. Therefore, the electrode clip 10 will not be electrified no matter how it is flipped, so as to avoid the danger of electric shock caused by children poking into the socket with metal parts. When the plug 22 is inserted into the socket, the electrical pin 23 of the plug 22 has two metal pieces, which is equivalent to inserting two metal pieces into the socket, and the metal piece on each electrical pin 23 can simultaneously drive the two auxiliary clips 3 to act. , to realize the simultaneous opening of the two-way four switches, the voltage on the live wire conductive sheet 16 or the neutral wire conductive sheet 17 is respectively applied to the two electrode clips 10 through the four auxiliary clips 3, and through the two main clips 2, Conducted to the electrical pins 23 of the plug 22 to achieve electrical connection.

The second type of socket with different functions is:

The housing 8 is provided with two conductive sheets 19, each conductive sheet 19 is provided with two electrical contact portions 21, an electrical contact portion 21 of each conductive sheet 19 and an auxiliary clip 3 of each electrode clip 10 Opposite and connected together. The connection together can be that the conductive sheet 19 is long on the electrode clip 10, so that the two become an integral structure. Alternatively, as shown in FIG. 14 , the two are approached along the dotted line, and are fixedly joined together by welding, riveting, etc., to realize an electrical connection structure. The other electrical contact portion 21 of each conductive sheet 19 is disposed opposite to the other auxiliary clip 3 of each electrode clip 10, and an insulating sheet or insulating layer 20 is provided therebetween, and the other electrical contact portion of each conductive sheet 19 The back of the contact portion 21 is respectively provided with a live wire conductive sheet 16 and a neutral wire conductive sheet 17, and another electrical contact portion 21 of each conductive sheet 19 is provided with a disconnection interval 18 between the live wire conductive sheet 16 and the neutral wire conductive sheet 17. .

The obvious difference from the technical effect of the first socket with different functions is:

When an electrical pin 23 of the plug 22 is inserted into a jack 9, in the jack 9, although the two auxiliary clips 3 on the corresponding electrode clips 10 are opened to both sides, they will not contact the live wire to conduct electricity. The electrode clip 10 in the other jack 9 will contact the neutral wire 17 or the live wire 16, so it is also effective to prevent the user from accidentally using the conductor When inserted into the jack 9, the electrode clip 10 is accidentally touched and an electric shock is generated, which greatly improves the safety of the electrical appliance.

As shown in Figures 5, 6, 7, 8, 10, 11, 15, and 16, the socket includes a housing 8, the housing 8 is provided with a socket 9, and the housing 8 is provided with the electrode clips 10 as described above. The electrode clip 10 shown in FIG. 10 can be replaced by a second type of electrode clip. The connecting piece 1 is set close to the inner side of the socket 9 , the openings of the pair of main clips 2 are set towards the bottom of the casing 8 , and the through hole 4 is set close to the inner side of the socket 9 .

The position of the through hole 4 close to the inner side of the insertion hole 9 is relative to the opening of the main clip 2, which is completely different from the installation structure of the electrode clip 10 in the prior art. With this structure, as shown in FIG. 10 , when the electrical pins 23 of the plug 22 are inserted into the socket, they first enter the through holes 4 through the jacks 9 , and then squeeze into the openings of the main clip 2 and the auxiliary clip 3 . Or as shown in Figures 5, 6, 7, and 8, first the jack 9 is squeezed into the opening of the main clip 2, then through the through hole 4, and finally squeezed into the opening of the auxiliary clip 3 to achieve electrical connection. . Since the main clip 2 and the auxiliary clip 3 are far from the jack 9 relative to the through hole 4, the electrical connection can only be achieved when most of the electrical pins 23 enter the jack 9, resulting in the socket 22 being connected to the socket 9. The distance between the upper surfaces of the socket shell 8 is very small to enable electricity, so that the fingers can be effectively prevented from being caught between the plug 22 seat and the socket shell 8 and touching the electrical pins 23 and getting an electric shock, so that the electrical appliance is plugged and used. Safer and more reliable.

Based on a general inventive concept, the second type of socket shown in Figures 15 and 16, which is a socket with a ground wire, includes a shell 8, the shell 8 is provided with a socket 9, and the shell 8 is provided with the above-mentioned The second type of electrode clip 10, the casing 8 is provided with a longitudinal wall 13, and the fixing piece 5 is fixed on the longitudinal wall 13. In use, a corresponding three-pin plug (not shown in the figure) needs to be matched, and the three-pin plug also includes a pair of electrical pins 23 and a ground pin 26 .

The fixing piece 5 is fixed on the longitudinal wall surface 13, which can prevent the electrode clip 10 from moving in the housing 8, avoid the relative change of the position between the electrode clip 10 and the jack 9 due to the contact of the electrical pins 23 of the plug 22, and is convenient for the plug 22 electrical pins 23 for insertion.

The housing 8 is provided with a front cover 11 and a rear seat 12, the insertion hole 9 is arranged on the front cover 11, the longitudinal wall 13 is arranged on the front cover 11 or the rear seat 12, and the fixing piece 5 is arranged on the top surface of the longitudinal wall 13 and the rear seat 12. Or the inner surfaces of the front cover 11 are clamped and fixed.

During assembly, as long as the front cover 11 and the rear seat 12 of the housing 8 are fastened together, the top surface of the longitudinal wall surface 13 will be close to the rear seat 12 or the inner surface of the front cover 11, so that the fixing piece 5 is supported on the longitudinal wall surface. 13 The top surface is fixed, so that the electrode clip 10 cannot move back and forth in the casing 8, and the assembly is convenient and fast.

An electrode slot 15 is provided at a position opposite to the insertion hole 9 beside the longitudinal wall 13 , and the electrode clip 10 is arranged in the electrode slot 15 .

The longitudinal wall surface 13 is provided with a slot 14 , and the fixing piece 5 is arranged in the slot 14 . The setting of the card slot 14 can not only accurately locate the electrode clip 10 in the housing 8, but also avoid using fasteners such as screws to fix the electrode clip 10, so that the assembly is simple and fast. After the front cover 11 and the rear seat 12 are combined together, the slot 14 forms a fixing hole in the casing 8 , and the fixing sheet 5 can be firmly fixed therein, so that the electrode clip 10 can obtain a good fixing effect in the casing 8 . Due to the different positions of the fixing pieces 5 in the first and second electrode clips, the depths of the slots 14 on the longitudinal wall 13 are correspondingly different, as shown by the solid and dotted lines of the slots 14 in FIG. 10 . When installing the second type of electrode clip, the card slot 14 is deeper than the first type, and a card plate (not shown in the figure) is arranged on the inner side of the front cover 11 at a corresponding position, so that the card plate is inserted into the card slot 14 , the fixing sheet 5 can also be fixed in the slot 14 .

As shown in FIGS. 10 and 11 , two electrode grooves 15 are provided on the rear seat 12 , and the two sides of the two longitudinal walls 13 are surrounded to form the electrode grooves 15 . As shown in FIG. 11, two electrode clips 10 are placed therein, respectively. The electrode slot 15 can limit the movable range of the electrode clip 10, so that it is relatively fixed in the housing 8, and at the same time, it also isolates electricity to a certain extent, which greatly improves the creepage distance between the internal conductors. In addition, even if a small piece of metal falls into the socket 9, it is eventually confined in the electrode groove 15, and it will not cause an internal short circuit to cause fire and burn, which also improves the safety of the electrical appliance. During installation, the electrode clip 10 can be placed in the electrode groove 15 to pre-determine the position in the housing 8, and then the front cover 11 and the rear seat 12 are snapped together, which is also convenient and quick to assemble.
