Description

TECHNICAL FIELD

[0001] The present application relates to the field of circuit switch, in particular to a switch swing piece structure and a switch thereof. BACKGROUND

[0002] The swing piece switch is a kind of mechanical switch widely used in various electrical equipment, due to its simple structure, reliable performance and low cost, it is widely used in household appliances, industrial control, automobile electronics and other fields. Its working principle is based on mechanical movement, through the external force acting on the operating part, the swing piece swings and flips, so as to touch the contact and realize the on-off of the circuit. The main components of the swing piece switch include switch shell, key, swing piece, spring and contact.

[0003] In the assembly process of the traditional swing piece switch, there are mainly two processing methods for the swing piece. One is to adopt full silver contact design, that is, to coat silver layer on both sides of the contact of the swing piece. The advantage of this design is that even if the swing piece is installed reversely during assembly, the contact conductivity will not be affected, because no matter which side contacts the contact, there will be a silver layer to provide good conductivity. However, the main disadvantage of full silver contact design is the high cost, because silver is a relatively expensive material, and its large-scale use will significantly increase the production cost. Another common processing method is to use single-sided silver layer contact, which only coats silver layer on one side of the contact of the swing piece. In this case, it is necessary to ensure correct identification and installation of the swing piece during assembly. If the swing piece is installed reversely, the contact position will not be covered with silver layer, which will cause the contact conductivity to decrease significantly, affecting the normal function of the switch. Although the single-sided silver layer contact design can reduce the material cost, it requires higher assembly precision and process.

[0004] In actual production and assembly process, even if strict operating procedures and inspection standards are formulated, the problem of swing piece installation reversal is still prone to occur. This is mainly due to the inevitable mistakes of manual operation, and the identification and assembly errors that may occur when the automatic equipment is running at high speed. Such assembly errors not only cause the switch performance to decrease, but also may cause the electrical equipment to malfunction, thereby affecting the overall quality of the product and the user experience. SUMMARY

[0005] The purpose of the present application is to provide a switch swing piece structure and a switch thereof which are low in cost and cannot be installed reversely.

[0026] In summary, the present application has the following advantages over the prior art: The anti-reverse installation structure formed by the cooperation of the limiting groove, limiting block, and limiting protrusion on the swing piece ensures that the swing piece can only be installed in the correct direction. This effectively reduces the problem of reduced contact conductivity or switch failure caused by reverse installation of the swing piece, greatly improving the assembly qualification rate and reliability of the product. Furthermore, the anti-reverse installation structure makes the installation of the swing piece more simple and intuitive, reducing the need for direction judgment by the operator during assembly, thereby simplifying the assembly process. This not only improves production efficiency but also reduces the technical level required for the operator.

[0027] In addition, one end of the first conductive contact extends to the bottom of the first swing piece and second swing piece and contacts them.

In the cavity 10 is provided with an incoming line terminal 2 and outgoing line terminals 3 respectively arranged on the left and right sides of the incoming line terminal 2, the incoming line terminal 2 is connected with a first conductive contact 21, one end of the first conductive contact 21 is bent and extends out along the bottom of the cavity 10, two outgoing line terminals 3 are respectively connected with a second conductive contact 31. On the bottom surface of the cavity 10 on one side of the incoming line terminal 2 and the outgoing line terminals 3 is fixed with a swing slot 4 composed of a first slot 43 and a second slot 44 side by side, the first slot 43 and the second slot 44 are adjacent to the corresponding second conductive contact 31; in the first slot 43 and the second slot 44 are respectively swingably inserted with a first swing blade 51 and a second swing blade 52, the first swing blade 51 and the second swing blade 52 form a swing blade assembly 5, the first swing blade 51 and the second swing blade 52 can swing in opposite directions in the respective swing slot 4 following the swing of the corresponding switch key 6, thereby making contact or breaking with the second conductive contact 31; one end of the first conductive contact 21 extends out along the bottom of the cavity 10 and finally bifurcates into a "Y" shape to extend to the bottom of the first swing blade 51 and the second swing blade 52 respectively, and make contact with the bottom of the first swing blade 51 and the second swing blade 52 for conductive connection. Anti-reverse installation structure 40 is respectively arranged on the left and right sides of the swing slot 4 to prevent the first swing blade 51 from being installed reversely when inserted into the swing slot 4.

[0043] Among them, as Figures 1 to 5As shown, in this embodiment, the incoming terminal 2 is arranged on the side opposite to the central position adjacent to the first slot 43 and the second slot 44, and the outgoing terminal 3 corresponds to the first slot 43 and the second slot 44, respectively. A notch is arranged at the bottom center of the first slot 43 and the second slot 44, respectively, to accommodate the extension of one end of the first conductive contact 21 along the bottom surface of the accommodation cavity 10. The corresponding notch separates the first slot 43 and the second slot 44 into two spaced slots. The first swing piece 51 is swingably inserted into the first slot 43, and the second swing piece 52 is swingably inserted into the second slot 44. The bottom end of the first swing piece 51 abuts the first conductive contact 21 at the bottom of the first slot 43, and the bottom end of the second swing piece 52 abuts the first conductive contact 21 at the bottom of the second slot 44. Among them, the anti-reverse installation structure 40 includes a limiting groove 41 and a limiting block 42. In this embodiment, the limiting groove 41 is arranged on the left side of the first slot 43, and the limiting block 42 is arranged on the right side of the second slot 44. As an example, a limiting protrusion 50 is arranged on the left edge of the first swing piece 51 and protrudes outward, which can cooperate with the limiting groove 41. It should be noted that the limiting groove 41 and the limiting block 42 can be exchanged, that is, the limiting block 42 does not have to be arranged on the right side of the second slot 44, but can be arranged on the left side of the first slot 43, and the limiting groove 41 can be arranged on the right side of the second slot 44. In this way, the limiting protrusion 50 is arranged on the right side of the second swing piece 52. The driving part 53 and the contact part 54 protruding upward on the top end of the first swing piece 51 and the second swing piece 52 are arranged for connecting with the corresponding switch key 6.

When the first swing piece 51 is mistakenly inserted into the second slot 44, it will be blocked by the protruding limiting block 42 due to the limiting protrusion 50, and cannot be inserted downward. However, when the first swing piece 51 is correctly inserted into the first slot 43, the limiting protrusion 50 can be accommodated in the limiting groove 41 due to the space of the limiting groove 41, and will not be blocked. It should be noted that the second swing piece 52 does not have a limiting protrusion 50, and can be freely inserted into the second slot 44. It should be further emphasized that the swing piece assembly 5 in this embodiment includes the first swing piece 51 and the second swing piece 52, and the outgoing terminal 3 also takes two as an example.

[0044] In order to make the first swing piece 51 and the second swing piece 52 swing more freely in the slot, the front and rear inner side walls of the first slot 43 and the second slot 44 are respectively inclined outwardly near the top end. In order to prevent the swing angle of the first swing piece 51 and the second swing piece 52 from being too large, a limiting column 11 is arranged at the rear side of the first slot 43 and the second slot 44 respectively.

[0045] In addition, as shown in Figures 6 to 10 The embodiment of the switch of the present application is shown in the figure.

A button base 7 is arranged on the switch base 1 to cover the top opening of the cavity 10. Symmetrical switch buttons 6 are hingedly connected to the button base 7. A driving piece 8 is arranged at the bottom of the switch button 6 to extend into the cavity 10 through the button base 7. The bottom end of the driving piece 8 is movably connected to the swing piece assembly 5. When the switch button 6 is pressed, the driving piece 8 connected to the bottom of the switch button 6 drives the swing piece assembly 5 to swing in the opposite direction in the swing slot 4, so that the swing piece assembly 5 is in contact with or separated from the second conductive contact piece 31 to realize the power-on or power-off of the circuit connected to one end of the outlet terminal 3.

[0046] Specifically: with double open switch as an example, terminal groove 12 capable of accommodating incoming terminal 2 and outgoing terminal 3 respectively is arranged in the cavity 10, and the terminal groove 12 is in the form of three parallel long strip-shaped grooves, the central one is the terminal groove 12 in which the incoming terminal 2 is embedded, and the left and right two are the terminal grooves 12 in which the outgoing terminals 3 are embedded. The outer wall of the switch base 1 is respectively penetrated by the wiring hole 13 capable of communicating with each terminal groove 12. The strip-shaped groove 71 is symmetrically arranged on the key base 7, the toggle member 8 is respectively hinged in the strip-shaped groove 71, the toggle groove 72 capable of communicating with the cavity 10 is penetrated at the bottom of the strip-shaped groove 71, the bottom of the toggle member 8 is provided with the toggle rod 81 capable of penetrating the toggle groove 72 and movably connected with the top of the corresponding first swing piece 51 and the second swing piece 52 at the bottom end, the bottom end of the toggle rod 81 is provided with the clamping groove 84 capable of being inserted into the first swing piece 51 and the second swing piece 52, and the top of the two toggle members 8 is connected with the bottom surface of the corresponding switch key 6. The spring groove 82 is respectively arranged in the toggle rod 81, the bottom end of the spring groove 82 penetrates the bottom end of the toggle rod 81, the spring 83 is respectively arranged in each spring groove 82, the bottom end of the spring 83 extends out of the opening at the bottom of the spring groove 82 and abuts against the driving part 53 of the corresponding first swing piece 51 and the second swing piece 52, and in the process of switch operation, the spring 83 applies appropriate pressure to make the second conductive contact point 55 on the first swing piece 51 and the second swing piece 52 maintain good contact with the corresponding first conductive contact point 32. Such pressure ensures stable conductivity of the circuit when the switch is closed, and avoids resistance increase or circuit disconnection caused by poor contact.
