To further clarify the technical solutions and effects adopted by the present application to achieve the intended purpose, the following detailed description is given with reference to the accompanying drawings and preferred embodiments according to the present application. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The utility model discloses an arc-proof power connector is an electrical switch that can reduce and produce electric arc phenomenon when switching on or breaking off with power supply, can extensively be used for the use occasion that needs frequent switch-on respectively, disconnection, for example be arranged in among the domestic appliance.

Referring to fig. 1 and 2, the arc-proof power connector (also referred to as "connector") 4 includes a lower cover 41, an upper cover 42, a sliding cover 43, a conductive elastic sheet 45 and a microswitch 46; the upper cover 42 is assembled on the lower cover 41, an electrical cavity is formed between the upper cover 42 and the lower cover 41, and a first plug hole 421 communicated with the electrical cavity is formed in the upper cover 42; the conductive elastic piece 45 comprises a connecting end 451 fixed on the lower side surface of the upper cover 42 and a conductive end 452 connected with the connecting end 451, and the conductive end 452 is positioned right below the first inserting hole 421; the sliding cover 43 is located between the upper cover 42 and the conductive elastic sheet 45, one end of the sliding cover 43 is arranged in the electric cavity through the first elastic piece 44 which can move horizontally, the sliding cover 43 is provided with a second inserting hole 431 corresponding to the first inserting hole 421, the hole wall of the second inserting hole 431 is provided with a guide part 432 which pushes the sliding cover 43 to enable the first elastic piece 44 to be compressed when a downward acting force is applied, and the guide part 432 is located right below the first inserting hole 421 when the first elastic piece 44 is not compressed; the micro switch 46 disposed in the electric cavity includes a switch body 461 and a spring plate 462 disposed on the top end surface of the switch body 461, and the spring plate 462 is located right below the conductive end 452 of the conductive spring 45.

When the arc-proof power connector 4 is in the non-conducting state or the non-using state, the first elastic element 44 is not compressed and is in the natural extension state, so that the sliding cover 43 is in the first position in the electrical cavity, at this time, the second insertion hole 431 and the first insertion hole 421 are arranged in a staggered manner, and the guide part 432 is located right below the first insertion hole 421, so that an external element cannot be inserted from the first insertion hole 421 and then acts on the conductive end 452 of the conductive elastic sheet 45, and therefore the reed 462 of the conductive end 452 of the conductive elastic sheet 45 facing the microswitch 46 cannot be pressed down, the microswitch 46 is in the off state, and the arc-proof power connector 4 is in the non-conducting state or the off state in electrical characteristics.

When an external component (e.g., a conductive pin) is inserted into the first insertion hole 421 from top to bottom, a downward force is applied to the guide portion 432, and the sliding cover 43 is pushed to move horizontally in a direction close to the first elastic member 44, so that the first elastic member 44 is compressed; when the sliding cover 43 horizontally slides in the electrical cavity to the second position when the second insertion hole 431 is aligned with the first insertion hole 421, the external component can smoothly further pass through the second insertion hole 431 and contact with the conductive end 452 of the conductive elastic piece 45, at this time, the reed 462 of the micro switch 46 is not pressed, and the micro switch 46 is still in the off state, so that the arc-proof power connector 4 still presents a non-conductive state or an off state in the electrical characteristic, and therefore the external component (such as the conductive pin) is not in electrical contact when contacting with the conductive end 452 of the conductive elastic piece 45, and an arc phenomenon cannot occur when the external component (such as the conductive pin) contacts with the conductive end 452 of the conductive elastic piece 45; as the external element (e.g., conductive pin) is further inserted, the conductive end 452 of the conductive elastic piece 45 is pushed to press toward the reed 462 of the micro switch 46, and the micro switch 46 is switched from the off state to the on state when the reed 462 of the micro switch 46 is pressed, so that the arc-proof power connector 4 is changed in electrical characteristic to the on state or the on state.

In one embodiment, the contact surfaces of conductive end 452 and spring 462 are provided with silver contacts, and the silver contacts of conductive end 452 are in contact with the silver contacts of spring 462, so that even when spring 462 is pressed by conductive end 452 against switch body 461 to switch micro-switch 46 from the off state to the on state, the arc generated by the silver contacts contacting the silver contacts is very small. The heating tube is limited by the existing process reason, the conductive needle of the heating tube can not be manufactured into a silver contact, usually a copper contact, and when a user takes out/puts in the heating plate or the saucepan after switching on the power supply, an electric arc phenomenon (striking fire) occurs between the conductive needle and the switch elastic sheet contact, so that the conductive needle can be burnt black. According to the scheme, the conductive elastic sheet 45 and the reed 462 with the silver contacts are skillfully arranged, the on-off of the circuit is controlled by the microswitch 46, and by utilizing the contact between the conductive needle and the conductive elastic sheet 45 and the time difference between the pressing of the reed 462 by the conductive elastic sheet 45, the microswitch 46 is in an off state when the conductive needle is in contact with the conductive elastic sheet 45, so that the conductive elastic sheet 45 is not electrified, and even if the conductive needle is provided with the copper contact, the conductive needle 23 is not in contact with the conductive elastic sheet 45 to generate an arc phenomenon. When the spring 462 is pressed down by the conductive spring 45 to close the circuit, the contact between the silver contacts will not generate the arc phenomenon.

In one embodiment, the conductive end 452 of the conductive elastic piece 45 is connected to the connection end 451 through an elastic section 453 bent upward from the connection end 451, so that the conductive end 452 has an upward elasticity relative to the connection end 451 through the elastic section 453, and the upward elasticity enables the conductive end 452 to be accurately separated from the spring 462 of the micro switch 46 when an external component (e.g., a conductive pin) is removed from the arc-proof power connector, thereby improving the operational reliability of the arc-proof power connector.

In one embodiment, in order to further improve the elastic capability of the conductive end 452 of the conductive elastic piece 45 relative to the connection end 451, a second elastic member 47 (for example, the second elastic member 47 is a spring or an elastic block) is disposed between the lower side surface of the conductive end 452 and the bottom of the electrical cavity, or/and between the spring 462 of the micro switch 46 and the bottom of the electrical cavity.

In one embodiment, an upper receiving chamber 423 is provided at a lower side of the upper cover 42, the sliding cover 43 is disposed in the upper receiving chamber 423, and the first elastic member 44 is disposed between the sliding cover 43 and an inner sidewall of the upper receiving chamber 423. For example, one end of the first elastic member 44 is fixedly connected to the sliding cover 43, and the other end of the first elastic member 44 abuts against the inner sidewall of the upper receiving chamber 423. This structure facilitates the assembly of the slide cover 43 and the first elastic member 44 through the upper receiving chamber 423, ensuring the reliability of the overall structure.

In one embodiment, a lower receiving chamber 413 is provided at an upper side of the lower cover 41, and the micro switch 46 is fixed in the lower receiving chamber 413; when the upper cover 42 is fitted on the lower cover 41, the upper accommodation chamber 423 is located above the lower accommodation chamber 413, and the upper accommodation chamber 423 and the lower accommodation chamber 413 together constitute an electrical chamber. This structure also allows for easy assembly and fixation of the slider 43 and the microswitch 46.

Wherein, a limit ring groove 425 is arranged on the lower side surface of the upper cover 42 around the upper accommodating cavity 423, and a surrounding baffle 413 is arranged on the upper side surface of the lower cover 41 around the lower accommodating cavity 413; when the upper cover 42 is assembled on the lower cover 41, the upper end of the enclosure 413 is inserted into the limiting ring groove 425, so that the assembling structure of the upper cover 42 and the lower cover 41 is more reliable, and the improvement of the reliability of the whole structure of the arc-proof power connector 4 is facilitated.

Even more, in order to facilitate the assembly between the upper cover 42 and the lower cover 41, the lower side surface of the upper cover 42 is provided with a positioning groove 424, and the upper side surface of the lower cover 41 is correspondingly provided with a positioning block 414; when the upper cover 42 is assembled to the lower cover 41, the positioning block 414 is located in the positioning groove 424.

In one embodiment, the periphery of the lower cover 41 is provided with a plurality of fixing holes 411, the lower side surface of the upper cover 42 is provided with a plurality of fixing posts 422 corresponding to the fixing holes 411, and the upper cover 42 is assembled on the lower cover 41 by screwing fixing members such as screws through the fixing holes 411 and the fixing posts 422 at corresponding positions.

Further referring to fig. 3-5, the specific structure and the operation principle of the arc-proof power connector 4 of the present invention will be further described by taking a split type electric baking pan as an example.

The split type electric baking pan (called 'electric baking pan' for short) comprises a power supply base 1 electrically connected with a power supply, an arc-proof power connector 4 arranged on the power supply base 1 and a pan component 2 which can be taken and placed on the power supply base 1; the pan assembly 2 comprises a pan body 21 and a heating tube 22 arranged at the bottom of the pan body 21, and two tail ends of the heating tube 22 are respectively provided with a conductive needle 23. When the pot component 2 is placed on the power base 1, the electric conduction needle 23 is inserted into the arc-proof power connector 4 from the first insertion hole 421, so that the power supply is connected with the heating tube 22 through the arc-proof power connector 4, and the heating tube 22 is powered on to heat food in the pot body 21.

Of course, the cover 3 may also be disposed on the power base 1, and the cover 3 may be rotatably mounted on the side of the power base 1, or may be removably disposed on the power base 1. Close on pot subassembly 2 through 3 lids of lid, be favorable to improving the culinary art efficiency when utilizing pot subassembly 2 culinary art food.

Wherein, be equipped with support column 24 respectively between conducting pin 23 and pot body 21 bottom, set up fore-set 25 between two conducting pins 23, the position that the fore-set 25 extends to the lower tip of fore-set 25 downwards from pot subassembly 2 bottom is less than conducting pin 23, and the fore-set 25 compares conducting pin 23 and down protrusion in conducting pin 23 setting promptly.

In a preferred embodiment, the first inserting hole 421 and the second inserting hole 431 are 3 holes arranged at intervals; the number of the conductive elastic pieces 45 is also 3, 3 conductive elastic pieces 45 are respectively located right below the 3 first inserting holes 421, the reed 462 of the micro switch 46 is located right below the conductive end 452 of one of the conductive elastic pieces 45, and the conductive ends 452 of the other two conductive elastic pieces 45 are respectively set as a ground end and a zero line end.

A first shielding wall is arranged between two adjacent first inserting holes 421, a second shielding wall is arranged between two adjacent second inserting holes 431, and the guide part 432 is arranged on the second shielding wall between the second inserting hole 431 at the middle position and the second inserting hole 431 close to the first elastic piece 44. When the sliding cover 43 is located at the first position in the electrical cavity, the second shielding wall on the sliding cover 43 is located in the first inserting hole 421 of the upper cover 42, and the conductive end 452 of the conductive elastic piece 45 is shielded by the second shielding wall, and the second inserting hole 431 on the sliding cover 43 is shielded by the first shielding wall of the upper cover 42, so that the conductive pin 23 cannot pass through the second inserting hole 431 of the sliding cover 43 to be connected with the conductive end 452 of the conductive elastic piece 45 in a contacting manner. When the sliding cover 43 is located at the second position in the electrical cavity, the second shielding wall on the sliding cover 43 overlaps with the first shielding wall on the upper cover 42, and each first inserting hole 421 on the upper cover 42 overlaps with a corresponding second inserting hole 431 on the sliding cover 43.

The conductive end 452 of the conductive elastic sheet 45 located at the middle position is a ground end, and is electrically connected to ground; the guide portion 432 is a slope extending from the second shielding wall between the second insertion hole 431 located at the intermediate position and the second insertion hole 431 adjacent to the first elastic member 44 toward the second insertion hole 431 located at the intermediate position.

When the pot assembly 2 is placed into the power base 1 from top to bottom, because the top post 25 is lower than the conductive pins 23, the top post 25 contacts the guide part 432 of the sliding cover 43, so that the sliding cover 43 moves in the direction of extruding the first elastic member 44 in the electrical cavity, that is, the sliding cover 43 moves from the first position to the second position in the electrical cavity, when the sliding cover 43 moves to the second position, each second insertion hole 431 of the sliding cover 43 respectively faces the first insertion hole 421 corresponding to the upper cover 42, so that the top post 25 and the two conductive pins 23 can be inserted into the first insertion hole 421 and pass through the second insertion hole 431.

Moreover, since the top pillar 25 is long, the top pillar is continuously inserted toward the lower cover 41, and the conductive terminal 452 of the conductive elastic piece 45 at the middle position is touched to be grounded. After the conductive end 452 of the conductive elastic sheet 45 at the middle position is grounded, the two conductive pins 23 will contact the conductive elastic sheet 45 at the corresponding position later, at this time, the reed 462 of the micro switch 46 is not pressed, and the micro switch 46 is in the off state, so that the conductive elastic sheet 45 is not electrified, and therefore, the conductive pins 23 are not in contact with the conductive elastic sheet 45 to generate an arc phenomenon. As the conductive pin 23 is further pressed after contacting the conductive elastic pieces 45, after the conductive end 452 of one of the conductive elastic pieces 45 presses the reed 462 of the micro switch 46 for a stroke, the micro switch 46 is activated to switch from the off state to the on state, so that the arc-proof power connector 4 is electrically switched from the off state to the on state, at this time, since the conductive end 452 of the conductive elastic piece 45 is preferably in contact with the reed 462 of the micro switch 46 by using a silver contact, an arc generated by the contact between the silver contact and the silver contact is very small, and therefore, when the micro switch 6 is turned on, the arc generated between the conductive elastic piece 45 and the reed 462 of the micro switch 46 is almost negligible.

As shown in fig. 6, R1 represents the heating tube 22, FU1 represents a fuse, T represents a thermostat, LED1 represents an indicator, S1 represents a power switch of the split cooking pot, and S2 represents the micro switch 46 of the arc-proof power connector 4. One end of the heating tube 22 is connected with the safe FU1, the temperature controller T, the power switch S1 and the microswitch 46 in series and then is connected with the live wire of the alternating current, and the other end of the heating tube 22 is connected with the zero wire of the alternating current. Therefore, when the power switch S1 is turned on, the heat generating tube 22 will be powered on to generate heat only when the micro switch 46 is in the on state.

The switch body of the microswitch 46 is connected to the live line ACL of the alternating current. When the pan assembly 2 is placed on the power base 1: the top pillar 25 grounds one conductive elastic sheet 45 (as a grounding end) at the middle position; two conductive pins 23 are inserted into the arc-proof power connector 4, one of the conductive pins 23 is in contact with one conductive elastic sheet 45 right below the conductive pin and then is in contact connection with the reed 462 of the micro switch 46, so that the micro switch 46 is switched from an off state to an on state, and the other conductive pin 23 is in contact with the other conductive elastic sheet 45 (as a zero line end) right below the conductive pin and then is connected with a zero line of alternating current, so that the heating tube 22 can be electrically operated.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
