[0028] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and cannot be used to limit the protection scope of the present invention.

[0029] Embodiment 1:

[0030] As Figures 1 to 10 shown, a connector with an open circuit mechanism includes: a housing 10; a first conductor assembly 20, including a first base 21, a wire pressing frame 22 installed in the first base 21, and a first conductor 23 installed in the wire pressing frame 22, the first base 21 being fixedly connected to the housing 10; a second conductor assembly 30, including a second base 31 and a second conductor 32 installed on the second base 31, the second base 31 being slidably connected to the housing 10; an open circuit mechanism 40, installed in the first conductor assembly 20, for making the first conductor and the second conductor in a connected state or a disconnected state. By the change of the temperature inside the connector in the connected state, the state of the temperature-sensitive element changes, so that the internal circuit of the connector changes from the connected state to the disconnected state. And in the disconnected state, the circuit is re-connected by pushing the sliding mechanism.

[0031] The first conductor assembly and the second conductor assembly are used to connect the entire circuit. When the circuit temperature is higher than the set value, the first conductor assembly and the second conductor assembly are separated through the action of the open circuit mechanism, so that the circuit changes from the on state to the off state. And when the temperature is higher than the set value, due to the setting of the open circuit mechanism, the circuit cannot return to the on state; when the circuit is in the off state and the temperature is lower than the set value, then push the second conductor assembly to move towards the first conductor assembly, so that the second conductor reconnects with the first conductor again, and at the same time the open circuit mechanism resets and the circuit conducts again.

[0032] In this embodiment, the disconnection method and reset method of the open circuit mechanism are constituted by elastic or inelastic parts; the open circuit mechanism has the characteristic of resetting the circuit to be connected; the open circuit mechanism is one or multiple paths, and the circuit is separated through temperature; a temperature threshold of the protection circuit is set, and the circuit cannot be connected when the temperature is higher than the set value.

[0033] As Figure 2 , Figure 5 , Figures 8 to 10 As shown, the first conductor assembly includes two first bases 21. The two first bases 21 are positioned and installed through positioning pins 211. A wire pressing frame 22 is installed in each first base 21. A first conductor 23 is installed in each wire pressing frame 22. A wire pressing gasket 24 is installed on a wire pressing screw 25. The wire pressing screw 25 is threadedly connected to the wire pressing frame 22. The wire pressing gasket 24 and the first conductor 23 cooperate to form a clamping mechanism for clamping the wire; on one side of the first conductor 23 facing the wire pressing gasket 24, there are a plurality of grooves or protrusions to play an anti-slip role and ensure that the wire is clamped between the wire pressing gasket 24 and the first conductor 23; during use, turn the wire pressing screw 25, and the wire pressing gasket 24 moves towards the first conductor 23 to clamp the wire. Reverse turn the wire pressing screw 25, and the wire pressing gasket 24 moves in the opposite direction of the first conductor 23 to loosen the wire. A transparent cover plate 26 is installed on one side of the wire pressing frame 22 to facilitate observing the internal wiring situation and understanding the operation of the circuit. In this embodiment, the first base 21 is a plastic base, which is composed of an inlet hole, a frame body feature for cooperating with the wire pressing frame 22, and a cavity feature for cooperating with the open circuit mechanism. The first conductor 23 has an insertion piece structure for inserting into the second conductor assembly. The wire pressing gasket 24 has a round hole chamfer structure. The wire pressing screw 25 is composed of a nut, a thread, a smooth rod and a riveting round hole. The wire pressing frame 22 is composed of a thread, inlet holes around, and a square frame for cooperating with the transparent cover plate 26 on the side.

[0034] As Figures 2 to 4 , Figure 7As shown, the second conductor assembly 30 includes a second base 31, a second conductor 32 and a second spring 33 mounted on the second base 31. One end of the second spring 33 is connected to the second base 31, and the other end of the second spring 33 abuts against the first base 21. The second conductor assembly 30 further includes a first push rod 34, one end of the first push rod 34 being connected to the second base 31. The second base 31 is provided with a first card slot 35.

[0035] As Figures 2 to 6 As shown, the open circuit mechanism 40 includes a thermosensitive metal sheet 41, a hanging shaft 42, a first spring 43, a hook 44, a torsion spring 45 and a pin shaft 46. There are two first bases 21. The hook 44 is mounted on one of the first bases 21 through the torsion spring 45 and the pin shaft 46. One end of the hook 44 is lapped on the hanging shaft 42, and the other end of the hook 44 is clamped with the first card slot 35. There are two right-angle hooks on the torsion spring 45 for hooking on the hook 44 and the first base 21 to facilitate the reset of the hook 44. There is an installation hole for the pin shaft 46 on the hook 44, and the head has a hook feature and is mutually hooked (clamped) with the second conductor assembly 30. One end of the hanging shaft 42 abuts against one side of the thermosensitive metal sheet 41 through the second push rod 421. The diameter of the second push rod 421 is smaller than that of the hanging shaft 42. The other side of the thermosensitive metal sheet 41 abuts against the wire pressing frame 22 in one of the first bases 21. The other end of the hanging shaft 42 abuts against the other first base 21 through the first spring 43. The thermosensitive metal sheet 41 is conical. The second push rod 421 abuts against the concave surface of the conical thermosensitive metal sheet 41, and the convex surface of the conical thermosensitive metal sheet 41 abuts against the surface of the wire pressing frame 22. The hook 44 has an oval head 441 at the end clamped with the first card slot 35. When the hook 44 is disconnected from the first card slot 35, the oval head of the hook 44 is still located in the first card slot 35. The long oval structure protruding from the head of the hook 44 can make the oval head always remain in the first card slot 35 provided on the second base 31 after the hook 44 is disengaged. The tail of the hook 44 has a double-layer bend for easy lapping on the hanging shaft 42. The hanging shaft 42 is cooperated with the hook 44 through the small round shaft feature (i.e., the second push rod 421, and the second push rod 421 is coaxially connected with the hanging shaft 42), and the large round shaft feature (i.e., the hanging shaft 42) is cooperated with the first base 21 and the first spring 43.

[0036] The second spring 33 is a conventional standard spring with one end connected to the second base 31 and the other end abutting against the first base 21. Its normal state is a compressed state. When the circuit temperature rises to the set temperature, the conical thermal-sensitive metal sheet 41 expands due to the heat, pushing the second push rod 421 and the hanging shaft 42, and compressing the first spring 43. The end of the hook 44 that is overlapped on the hanging shaft 42 slides off the hanging shaft 42 and overlaps the second push rod 421. At the same time, the other end of the hook 44 tilts up, causing the hook 44 and the second base 31 to be disconnected from the clamping state. When the hook 44 is disconnected, the second spring 33 pushes the second conductor assembly 30 away from the first conductor assembly 20 as a whole, separating the first conductor 23 and the second conductor 32, and realizing the circuit breaking action (at this time, the long oval head of the hook 44 is still deep in the first clamping groove 35 of the second base 31). After the temperature is lowered to the set temperature, the thermosensitive metal sheet 41 is reset. At this time, since the diameter of the hanging shaft 42 is larger than the diameter of the second push rod 421, under the action of the torsion spring 45 and the first spring 43, the hook 44 is in contact with the side of the hanging shaft 42 and will not return to the initial state; when it is necessary to restore to the initial normal state and reconnect the circuit, the first push rod 34 pushes the second base 31 toward the first conductor assembly 20, and the second conductor assembly 30 is pushed toward the first conductor assembly 20 as a whole. The hook 44 is inserted into the first card slot 35 and re-engaged with the second base 31. The other end of the hook 44 is re-connected to the hanging shaft 42, and the circuit breaker mechanism 40 is reset, so that the first conductor 23 and the second conductor 32 are reconnected, and the circuit is reconnected.

[0037] The second conductor 32 has sliding clips at both ends, allowing it to slide consistently on the conductor, reducing insertion resistance and maintaining a constant connection with the second base 31. The second base 31 is an insulating base. The second conductor 32 is placed on the insulating base, ensuring it remains aligned with the insulating base. The second base 31 has a feature that interconnects with the second spring 33, ensuring one end of the second spring 33 remains connected to the second base 31. The second base 31 has a long post feature (i.e., a first push rod 34). After the circuit is disconnected, the long post feature can be pressed manually or with a tool to reset the second conductor assembly 30, allowing the feature on the second base 31 in the second conductor assembly 30 to remain hooked to the hook 44, thereby restoring the circuit connection and ensuring a smooth circuit connection.

[0038] like Figure 5 、 Figure 6As shown in the figure, in this embodiment, the installation of the open circuit mechanism 40 is facilitated by two adjacent first bases 21. A first guide groove 27 for providing a guiding function is provided on one of the first bases 21, and the hanging shaft 42 is slidably connected to the first guide groove 27. A second guide groove 422 for accommodating the first spring 43 and guiding the first spring 43 is provided on the hanging shaft 42. On the other first base, there is an installation plate 28 for pressing the edge of the thermosensitive metal sheet 41 against the surface of the wire pressing frame 22. A groove matching the convex surface of the thermosensitive metal sheet 41 is provided on the surface of the wire pressing frame 22. A third guide groove for the second push rod 421 to pass through and slide freely is provided on the installation plate 28.

[0039] In this embodiment, the thermosensitive metal sheet 41 is made of BH-3 material. Such thermosensitive metal sheets are widely used in temperature control switch protector products, and their action temperature can be specifically customized according to the usage scenario.

[0040] In this embodiment, by providing an open circuit mechanism inside the connector, the circuit connection can be automatically disconnected after the temperature inside the connector rises to the set temperature, avoiding damage to the connector due to temperature increase and protecting the circuit safety. After the open circuit mechanism is disconnected, it will not automatically reset and must be manually reset after troubleshooting, improving the safety of the connector and avoiding the problem of the open circuit mechanism failure caused by misoperation.

[0041] Embodiment Two:

[0042] Based on the connector with an open circuit mechanism described in Embodiment One, this embodiment provides a usage method for the connector with an open circuit mechanism, including:

[0043] In the normal use state, the open circuit mechanism is in the closed state, the first conductor and the second conductor are in the connected state, and the circuit is conducting.

[0044] When the internal temperature of the connector rises abnormally and reaches the action temperature of the open circuit mechanism, the open circuit mechanism acts to disconnect the second conductor and the first conductor, and keeps the first conductor and the second conductor in the disconnected state.

[0045] When the internal temperature of the connector drops to the set temperature, then push the second conductor assembly in the direction of the first conductor assembly to make the second conductor reconnect with the first conductor, and at the same time the open circuit mechanism resets and the circuit conducts again.

[0046] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
