When the temperature in the mounting hole 6 is greater than the preset temperature, the first thermal bimetal 7 undergoes a bending deformation in which the bending degree of the active layer is greater than the bending degree of the passive layer, so that the two first feelers 71 of the first thermal bimetal 7 move in the opposite direction of the first direction F1 in the width direction of the second insulating mounting seat 201, so as to overcome the elastic force of the spring 1 to push the first branch arm 108 to separate from the first conductive sheet 204 and / or push the second branch arm 109 to separate from the second conductive sheet 205.When the temperature in the mounting hole 6 is greater than the preset temperature (the temperature is too high), it indicates that there is a short circuit or some bad connection in the connection circuit of the harpoon plug-in shunt connector, and the first thermal bimetallic strip 7 moves in the opposite direction of the first direction F1 in the width direction of the second insulating mounting seat 201 to push the first branch arm 108 to separate from the first conductive sheet 204 and / or push the second branch arm 109 to separate from the second conductive sheet 205, which can disconnect the electrical connection between the harpoon-type connecting conductive sheet 103 and the first conductive sheet 204 and / or the second conductive sheet 205, thereby providing power-off protection for the harpoon-type plug-in shunt connector.

[0025] See also Figure 8 , Fig.10 and Fig.11 According to a preferred embodiment of the present application, two first limiting grooves 206 arranged at intervals are formed on the side surfaces of the first conductive sheet 204 and the second conductive sheet 205, and two second limiting grooves 112 arranged at intervals are formed on the side surfaces of the first branch arm 108 and the second branch arm 109.

[0026] See also Figure 1 , Figures 7 to 11According to a preferred embodiment of the present application, a first heat conducting channel 113 and a second heat conducting channel 114 are provided in the first insulating mounting seat 101. The first end of the first heat conducting channel 113 leads to the mounting cavity 104, and the second end of the first heat conducting channel 113 leads to the mounting hole 6 connected to the first channel 202; the first end of the second heat conducting channel 114 leads to the mounting cavity 104, and the second end of the second heat conducting channel 114 leads to the mounting hole 6 connected to the second channel 203. In this embodiment, if the temperature of the mounting hole 6 of the second insulating mounting seat 201 is not high, but the temperature of the mounting cavity 104 in the first insulating mounting seat 101 is too high, this also indicates that the connection circuit of the harpoon type plug-in shunt connector is There is a short circuit or some bad connection. At this time, through the guidance of the first heat conducting channel 113 and the second heat conducting channel 114, the heat in the mounting cavity 104 can be gradually conducted to the mounting hole 6 of the second insulating mounting seat 201, which may still trigger the first thermal bimetallic strip 7 to move in the opposite direction of the first direction F1 in the width direction of the second insulating mounting seat 201 to push the first branch arm 108 to separate from the first conductive sheet 204 and / or push the second branch arm 109 to separate from the second conductive sheet 205.

[0027] See also Figure 1 Furthermore, the first heat-conducting channel 113 gradually narrows from its first end toward its second end, and the second heat-conducting channel 114 gradually narrows from its first end toward its second end. The first heat-conducting channel 113 and the second heat-conducting channel 114 are each provided with a thermal insulation coating on their respective channel walls. The gradually narrowing design of the first heat-conducting channel 113 and the second heat-conducting channel 114 can produce a narrow tube effect, that is, the airflow will converge to the narrowing point, which can, to a certain extent, promote the heat in the mounting cavity 104 to quickly reach the mounting hole 6 along with the airflow through the first heat-conducting channel 113 and the second heat-conducting channel 114. The gradual narrowing of the first heat-conducting channel 113 and the second heat-conducting channel 114 gradually accelerates the hot air flow toward the mounting hole 6 to avoid heat loss. The thermal insulation coating can also avoid heat loss, so that when the temperature in the mounting cavity 104 is too high, the bending movement of the first thermal bimetallic strip 7 in the mounting hole 6 can be well triggered.

[0028] See also Figure 1 , Figure 2 , Figure 5 , Figures 7 to 11According to one embodiment of the present application, the harpoon-type plug-in shunt connector includes a second thermal bimetallic strip 9, which is limited between the limit block 8 and the second side hole wall 62 of the mounting hole 6, the expansion coefficient of the active layer of the second thermal bimetallic strip 9 is greater than the expansion coefficient of its passive layer, and the active layer and the passive layer of the second thermal bimetallic strip 9 are arranged in sequence along the first direction F1 in the width direction of the second insulating mounting seat 201, and the second thermal bimetallic strip 9 extends two second antennae 91 toward the outside of the second insulating mounting seat 201, and an alarm light 10 is connected to the first insulating mounting seat 101, and the alarm light 10 is exposed to the outside of the first insulating mounting seat 101, and the first insulating mounting seat 101 forms a conductive switching cavity at a position corresponding to the upper end of the second thermal bimetallic strip 9, and the conductive switching cavity has a first wire terminal 11 and a second wire terminal 12 electrically connected to the alarm light 10 respectively, and when the input module 100 and the output module 200 are plugged into place with each other, the mounting hole 6 corresponding to the first channel 202 The two second antennae 91 of the second thermal bimetal strip 9 are respectively separated from the first wire terminal 11 and the second wire terminal 12 in the corresponding conductive switching cavity. When the temperature in the mounting hole 6 is greater than the preset temperature, the second thermal bimetal strip 9 undergoes a bending deformation in which the bending degree of its active layer is greater than the bending degree of the passive layer, so that the two second antennae 91 of the second thermal bimetal strip 9 move toward the first direction F1 in the width direction of the second insulating mounting seat 201 to contact the first wire terminal 11 and the second wire terminal 12 respectively. The second thermal bimetal strip 9 forms a conductive loop with the first wire terminal 11 and the second wire terminal 12 (a micro battery can be connected to the loop), so that the alarm light 10 is energized and turned on. All first wire terminals 11 and second wire terminals 12 can correspond to one alarm light 10, or each group of first wire terminals 11 and second wire terminals 12 can be equipped with an independent alarm light 10, so as to facilitate the knowledge of which mounting hole 6 the second thermal bimetal strip 9 has undergone bending changes.

[0029] It should be explained that the first thermal bimetallic strip 7 and the second thermal bimetallic strip 9 are both bimetallic strips, which are a composite material composed of two or more metals or other materials with suitable properties. Bimetallic strips are also called thermal bimetallic strips. Since the thermal expansion coefficients of the component layers are different, when the temperature rises, the deformation of the active layer is greater than that of the passive layer, so that the entire bimetallic strip will bend toward the passive layer. Usually, when the bimetallic strip cools, it will automatically rebound to the initial position (unbent state).

[0030] See also Figure 12 to Figure 14Although it is mentioned above that the bimetallic strip will automatically rebound to its initial position after cooling, in order to avoid the phenomenon that the bimetallic strip may not automatically rebound to its initial position, ensure the normal operation of the harpoon-type plug-in shunt connector, and be applicable to situations where the bimetallic strip needs to be manually forced to be driven to its initial unbent state, the harpoon-type plug-in shunt connector also includes a return mechanism 300, which includes a knob 301 rotatably mounted on the first insulating mounting seat 101 and a knob shaft 302 coaxially connected to the knob 301, the knob shaft 302 is rotatably inserted into the knob shaft cavity 116 inside the first insulating mounting seat 101, and a The insulating traction wire 303 corresponds to the number of conductive switching cavities (also corresponds to the number of mounting holes 6), and a limiting groove 306 corresponding to the number and position of the insulating traction wire 303 can be formed on the circumferential surface of the knob shaft 302, so that the insulating traction wire 303 is limited in the limiting groove 306 without excessive movement along the axial direction of the knob shaft 302. The figure only shows the insulating traction wire 303 corresponding to the number of mounting holes 6 at the upper end of the second insulating mounting seat 201, and omits the insulating traction wire 303 corresponding to the number of mounting holes 6 at the lower end of the second insulating mounting seat 201. The interior of the first insulating mounting seat 101 forms a guide groove corresponding to the number of insulating traction wires 303 The lead wire channel 117, one end of each lead wire channel 117 is connected to the knob shaft cavity 116, and the other end of each lead wire channel 117 is connected to each conductive switching cavity one by one. Each insulating traction wire 303 forms a movable ring 304 extending into the corresponding conductive switching cavity. The end of the insulating traction wire 303 forms a through coil 305. The insulating traction wire 303 passes through the through coil 305, thereby forming a movable ring 304 that can be reduced or enlarged. The movable ring 304 surrounds the first thermal bimetallic strip 7 and the second thermal bimetallic strip 9. Specifically, in order to facilitate the position layout of the movable ring 304, the first thermal bimetallic strip 7 extends two second through coils toward the outside of the second insulating mounting seat 201. Three antennae 72, a movable ring 304 surrounds the two third antennae 72 of the first thermal bimetal 7 and the two second antennae 91 of the second thermal bimetal 9. When an external force twists the knob 301 to make the knob shaft 302 wind around the insulating traction wire 303, the diameter of the movable ring 304 is reduced, so that the movable ring 304 can hold the first thermal bimetal 7 and the second thermal bimetal 9 after bending and deformation to a non-bending deformation state. When the first thermal bimetal 7 and the second thermal bimetal 9 are bent and deformed, the diameter of the movable ring 304 can be expanded. Therefore, when the knob 301 is not subjected to any external force, the knob shaft 302 will not form any restraining force on the insulating traction wire 303.
