Description
Technical field
The utility model relates to a kind of electronic device, specifically is meant a kind of dual instrument transformer.
Background technology
Dual instrument transformer is used for input and the power supply component of intelligent plastic housing circuit breaker as intelligent controller, comprises instrument transformer lid, fast saturated instrument transformer, hollow mutual inductor, dividing plate, shield blade and instrument transformer pedestal.Because the structural limitations of breaker of plastic casing causes the fixing relatively difficulty of instrument transformer, need fixture of design to be fixed, or the window upper and lower, left and right face that directly passes instrument transformer by connecting plate is close to cooperate and fixes, the easy like this problem that causes the difficulty that closely cooperates of connecting plate and instrument transformer window size, be not that connecting plate wears be not exactly that to fit inside post gap bigger in the past, can not be solid fixing and influence the performance and the quality of circuit breaker.Need in addition to resist external electromagnetic interference, and the lead-in wire of traditional instrument transformer is pulled easily and is come off in assembling process by increasing shield blade.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and provides a kind of reasonable in design, the dual conveniently and solidly instrument transformer of mount.
For achieving the above object, the technical solution of the utility model is, include instrument transformer loam cake, fast saturated instrument transformer, dividing plate, hollow mutual inductor, instrument transformer pedestal, described instrument transformer pedestal is provided with the connection window, be set with longitudinally fixedly muscle on the madial wall of described connection window, this fixedly the cross-sectional width of muscle be provided with to connecting inner linear increase of window from the insertion end that connects window.By this setting, when connecting plate is inserted in the connection window of instrument transformer pedestal, connecting plate and fixedly between the muscle, along with the insertion of connecting plate is fastening gradually, therefore, even the size of connecting plate occurs under the situation of trickle change because of the influence of mismachining tolerance or other extraneous factors, connecting plate still can very conveniently firmly be fixed on and connect in the window, in addition, this setting, connect between window and the connecting plate with respect to fixing all sides of muscle and the space of dispelling the heat occurred, increased the heat dispersion of product, help improving useful life of the present utility model.
Further being provided with is that the longitudinal section of described fixedly muscle is a wedge shape, and this is provided with can also be that the longitudinal section of described fixedly muscle is the oblique angle triangle, and this is provided with can also be that the longitudinal section of described fixedly muscle is that oblique angle is trapezoidal.The utility model preferably adopts oblique angle trapezoidal, and prefastened effect is better.
Further be provided be described connection window be provided with fixedly muscle on four madial walls up and down.This is provided with the stability that has improved the fastening assembling of connecting plate.
Further being provided with is that the madial wall of described connection window is oblique setting, and its oblique direction is consistent with the incline direction of fixing muscle.So, the insertion end that connects window is bigger than the inner chi footpath that connects window, even the connecting plate change in size occurs, also can easily connecting plate be inserted in the connection window.
The inner chamber that further setting is described instrument transformer loam cake and instrument transformer pedestal is coated with the electromagnetic shielding enamelled coating.By this setting, having solved traditional instrument transformer need set up shield blade and prevent external electromagnetic interference, cause mechanism that complexity is set, problem such as take up room, this is provided with and adopts the electromagnetic shielding enamelled coating not only to be provided with conveniently, and mechanism is provided with simply, cost is low, and take the intracavity space of instrument transformer loam cake and instrument transformer pedestal hardly, for the design of instrument transformer internal structure provides the space, help improving characteristic of the present utility model.
The inner chamber that further setting is described instrument transformer pedestal is provided with the lead-in wire groove that extends to instrument transformer base side wall opening.By this setting, during assembling, the lead-in wire of saturated instrument transformer of speed and hollow mutual inductor just can be by this groove cabling that goes between, by the frictional force between lead-in wire groove and the instrument transformer lead-in wire, can avoid effectively causing coming off of instrument transformer lead-in wire owing to pulling to draw, the probability that minimizing equipment breaks down has improved product quality.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.

Embodiment
Embodiment of the present utility model shown in Fig. 1-5, include instrument transformer loam cake 1, the saturated instrument transformer 2 of speed, dividing plate 3, hollow mutual inductor 4, instrument transformer pedestal 5, described instrument transformer pedestal 5 is provided with and connects window 51, be set with longitudinally fixedly muscle 52 on the madial wall of described connection window 51, fixedly the cross-sectional width of muscle 52 is provided with to connecting inner linear increase of window from the insertion end that connects window, the utility model, the longitudinal section of described fixedly muscle is that wedge shape or oblique angle triangle or oblique angle are trapezoidal, present embodiment preferably adopts oblique angle trapezoidal, its prefastened effect is better, in addition, present embodiment has been in order to have improved the stability of connecting plate 6 fastening assemblings, described connection window 51 be provided with fixedly muscle 52 on four madial walls up and down.When the utility model is inserted in the connection window 51 of instrument transformer pedestal 5 at connecting plate 6, connecting plate 6 and fixedly between the muscle 52, fastening along with the insertion gradually of connecting plate 6, therefore, even the size of connecting plate 6 occurs under the situation of trickle change because of the influence of mismachining tolerance or other extraneous factors, connecting plate 6 still can very conveniently firmly be fixed on and connect in the window 51, in addition, the utility model connects between window 51 and the connecting plate 6 with respect to fixing all sides of muscle 52 and the space of dispelling the heat occurred, increase the heat dispersion of product, helped improving useful life of the present utility model.
In addition, the inner chamber of described instrument transformer loam cake 1 of present embodiment and instrument transformer pedestal 5 is coated with electromagnetic shielding enamelled coating 7.So having solved traditional instrument transformer need set up shield blade and prevent external electromagnetic interference, cause mechanism that complexity is set, problem such as take up room, present embodiment adopts electromagnetic shielding enamelled coating 7 not only to be provided with conveniently, mechanism is provided with simply, and cost is low, and takies the intracavity space of instrument transformer loam cake and instrument transformer pedestal hardly, for the design of instrument transformer internal structure provides the space, help improving characteristic of the present utility model.
