Detailed Description
The technical scheme of the invention will be described below with reference to the accompanying drawings.
The combined temperature fuse of the first embodiment includes a housing 1, a wiring board 2, a conductive elastic sheet 3, a primary fuse element 4 and a resettable element 5, wherein the conductive elastic sheet 3 is made of an elastic material, such as copper.
The tab 2 includes a first tab 21, a second tab 22, and a center conductive tab 24; the first lug 21, the second lug 22 and the central conductive piece 24 are respectively fixedly connected with the shell 1. Typically, the housing 1 is provided with a first wiring port 11 and a second wiring port 12; the first and second connection tabs 21 and 22 are exposed from the first and second connection openings 11 and 12, respectively.
The primary fuse 4 includes a housing 41, temperature sensing particles 42, and a primary holding column 43; the temperature sensing particles 42 and the primary supporting columns 43 are sequentially connected and arranged in the shell 41, the primary supporting columns 43 extend out of the shell 41, and the cross-sectional area of the primary supporting columns 43 is smaller than that of the inner cavity of the shell 41. In general, the temperature sensitive particles 42 may be epoxy glass powder, or may be an object such as solidified quartz sand which changes its shape according to temperature, for example, changing from an integral state to a granular state or from a solid state to a liquid state.
In general, the primary holding post 43 may be attached to the temperature sensing particle 42, or may be connected to the temperature sensing particle 42 through a holding spring 44, for example, the temperature sensing particle 42 holds the top end of the housing 41, and both ends of the holding spring 44 hold the temperature sensing particle 42 and the holding spring 43, respectively. Typically, the bottom end of the supporting section 431 extends outwards to form a stop collar 433; both ends of the holding spring 44 hold the temperature sensing particles 42, 42 respectively.
The portion of the primary supporting column 43 located in the housing 41 is a supporting section 431; the portion of the primary abutment post 43 that protrudes from the primary abutment post 43 is an exposed section 432.
The resettable member 5 includes a bimetal 51 and a secondary abutment post 52, the bimetal 51 being in contact with the secondary abutment post 52. Generally, the bimetal 51 comprises a central disc 511 and an inclined edge disc 512, i.e. an angle is provided between the edge disc 512 and the central disc 511. The central plate 511 and the edge plates 512 are made of materials having different thermal expansion coefficients, and typically, the central plate 511 is made of a material having a larger thermal expansion coefficient, such as aluminum, and the edge plates 512 are made of a material having a smaller thermal expansion coefficient, such as beryllium copper, so that the central plate 511 is depressed downward when the temperature of the resettable member 5 increases, and the shape of the central plate 511 is restored when the temperature is restored.
The primary fuse 4 and the resettable member 5 are exposed from the top end of the housing 1. For example, the housing 1 includes a bottom case 14 and a middle case 15; the middle case 15 is provided with a primary mounting groove 151 and a holding post groove 152, the primary fuse 4 is inserted into the primary mounting groove 151, the bimetal 51 is positioned on the top end surface of the middle case 15, and the secondary holding post 52 is inserted into the holding post groove 152.
Further, the first wiring port 11 and the second wiring port 12 are both opened on the bottom shell 14 and exposed from the top end of the bottom shell 14, the middle shell 15 is provided with a first supporting leg 153 and a second supporting leg 154 extending downward, the first supporting leg 153 and the second supporting leg 154 are respectively embedded into the first wiring port 11 and the second wiring port 12, and screws respectively penetrate through the bottom shell 14 and are in threaded connection with the first supporting leg 153 and the second supporting leg 154. When the combined type temperature fuse is assembled, the first wiring lug 21 and the second wiring lug 22 can respectively move downwards from the top end opening of the bottom shell 14 and cannot be blocked by the middle shell 15, and meanwhile, the first wiring lug 21 and the second wiring lug 22 can incline when being assembled, so that the conductive elastic sheet 3 can be conveniently inserted below the central conductive sheet 24; the assembly of the combined type temperature fuse is convenient.
Further, the combined type thermal fuse of the first embodiment further includes an upper cover 16 made of a heat conductive material [ usually aluminum ], and the upper cover 16 is provided with an exposed opening 161 and a temperature sensing coil 162; the upper cover 16 is fixedly connected with the middle case 15 [ normally, the edge of the middle case 15 is provided with a flange 159, the edge of the upper cover 16 is provided with a flange clamping groove 163, and the flange 159 is clamped into the flange clamping groove 163, so that the upper cover 16 is fixedly connected with the middle case 15 ], the primary fuse 4 is exposed from the exposed opening 161, and the bimetal 51 is positioned between the temperature sensing coil 162 and the middle case 15. Typically, the top end of the middle housing 15 is provided with a counterbore (not shown in the figures) for receiving the bimetal 51. The combined temperature fuse can be integrated, the bimetallic strip 51 can not fall off, and the transportation and the storage of the combined temperature fuse are convenient.
The first lug 21 and the second lug 22 are respectively connected with the central conductive sheet 24 through the conductive elastic sheet 3. For example, the conductive spring plate 3 is fixedly connected with the first lug 21 and the second lug 22 respectively. When the combined type temperature fuse is assembled, the central conductive sheet 24 is fixed in the shell 1, after the elasticity of the conductive elastic sheet 3 is regulated by the curved conductive elastic sheet 3, the first wiring sheet 21 and the second wiring sheet 22 are fixed on the shell 1, and the conductive elastic sheet 3 is not deformed to separate from the central conductive sheet 24 and the combined type temperature fuse is invalid due to deformation of the conductive elastic sheet 3 (caused by extrusion of transportation, and the like), or the elasticity of the conductive elastic sheet 3 is too small, and the primary supporting column 43 and/or the secondary supporting column 52 cannot be moved upwards due to the elasticity provided by the conductive elastic sheet 3, so that the combined type temperature fuse is invalid; the elasticity of the conductive spring plate 3 can be adjusted in advance, so that the combined type temperature fuse can be ensured not to lose effect.
Of course, as another embodiment [ example two ], the conductive spring pieces 3 may be fixedly connected to both ends of the central conductive piece 24, respectively.
The primary holding column 43 and the secondary holding column 52 are respectively contacted with the conductive spring plate 3.
The working principle of the combined temperature fuse of the first embodiment is as follows: before use, the combined type temperature fuse is fixed below an object to be measured (usually a heating plate of an electric kettle), the object to be measured is attached to the primary fuse 4 and the resettable member 5, and the first wiring piece 21 and the second wiring piece 22 are connected with a wire for passing current (usually a power wire of the electric kettle).
When the temperature of the measured object is higher than the temperature threshold of the resettable member 5 (usually 100 degrees celsius, usually because water is boiled), the central disk 511 is depressed downwards to prop against the secondary prop 52, and the secondary prop 52 props against the conductive spring sheet 3 to disconnect the second lug 22 from the central conductive sheet 24, so as to realize power failure; when the temperature of the measured object is recovered and is lower than the temperature threshold value of the resettable member 5 (typically 100 ℃), the desired shape of the central disc 511 is recovered, and the conductive spring sheet 3 resets to enable the second connection piece 22 to be communicated with the central conductive piece 24, so that power supply recovery is realized.
When the temperature of the measured object is higher than the temperature threshold value (usually 125 ℃) of the primary fuse 4, usually caused by short circuit, the temperature sensing particles 42 are converted from solid state to non-solid state (such as fluid or powder), and the primary supporting column 43 moves upwards to disconnect the conductive spring sheet 3 from the central conductive sheet 24, so as to realize power failure; when the temperature of the measured object is recovered and is lower than the temperature threshold value of the primary fuse 4 (usually 100 ℃), the temperature sensing particles 42 cannot be recovered to be solid, and the conductive spring plate 3 cannot be reset, so that power failure can be ensured, and the electricity utilization safety when the measured object is overhauled is ensured.
From the above, it can be seen that the combined thermal fuse of the first embodiment can realize both recoverable power failure and one-time power failure.
In general, the tab 2 further includes a third tab 23, and the third tab 23 is fixedly connected to the central conductive tab 24 through the housing 1. The application range of the combined type temperature fuse can be enlarged, namely, the combined type temperature fuse is suitable for the situation of independent recoverable power failure or disposable power failure.
Typically, the top end of the housing 41 is a temperature sensing cap 411, and the temperature sensing cap 411 is screwed with the housing 41. The temperature sensing particles 42 are conveniently replaced as required.
It is to be understood that the terms "center," "longitudinal," "transverse," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the invention and simplify the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be configured and operated in a particular orientation, and thus should not be construed as limiting the scope of the invention.
