Abstract
The utility model relates to the technical field of electronic elements, in particular to a current transformer. The current transformer comprises a framework; a retaining sheet is arranged at the framework; an L-shaped pin is exposed at the bottom end of the retaining sheet; the corner of the pin is covered in the retaining sheet; and one end of the pin positioned outside the retaining sheet forms a connection terminal. The pin is L-shaped and one end of the pin positioned outside the retaining sheet forms the connection terminal, so that after a coil is welded with the connection terminal, the welding of the coil is not influenced by the welding of the pin self, thereby guaranteeing the product quality.
Description
Technical field
The utility model relates to technical field of electronic components, refers in particular to a kind of current transformer.
Background technology
Current transformer has catch on its skeleton, and the bottom of catch has pin, wherein, existing current transformer, behind coiling on the skeleton, directly the end with coil is welded on the pin.The current transformer of aforementioned structure, when assembling with circuit board, owing to the pin of current transformer need be welded on the circuit board, so, no matter be manual welding or machinery welding, all might influence very much the welding ends of coil and pin, make between coil and the pin no longer to be connected, thereby the quality problems of causing, and then influence production efficiency.
Therefore, based on the defective of above-mentioned existing current transformer, need improve existing current transformer.
The utility model content
The purpose of this utility model is to provide a kind of current transformer at the deficiencies in the prior art, this current transformer can Fast Installation on circuit board, simultaneously, when welding, can not influence being connected between coil and the pin, guarantee product quality.
For achieving the above object, the utility model is achieved through the following technical solutions: it comprises skeleton; Has catch on the skeleton; The catch bottom appears pin; Pin is " L type ", and the turning of this pin is coated in the catch; Pin is positioned at the outer wherein end of catch and constitutes terminals.
Offer groove on the described catch.
The side that described catch is positioned at pin has the indent platform.
Offer groove on the described indent platform.
Described catch has two, is symmetricly set on the skeleton.
The beneficial effects of the utility model are: because pin is " L type ", pin is positioned at the outer wherein end of catch and constitutes terminals, so, after coil and the terminals welding, the welding of pin itself can not impact the welding of coil, thereby guarantees product quality.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is another angle structural representation of the present utility model.
Reference numeral: 10---skeleton; 20---catch; 21---pin; 22---the indent platform; 23---groove; 24---terminals.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1,2, the utility model current transformer comprises: skeleton 10; Has catch 20 on the skeleton 10; Catch 20 bottoms appear pin 21; Pin 21 of the present utility model is " L type ", and the turning of this pin 21 is coated in the catch 20, the two ends of pin 21 are revealed in outside the catch 20, as shown in FIG., the pin 21 of catch 20 upper parts promptly is to be used for current transformer is welded in circuit board, the end that pin 21 is positioned at catch 20 sides constitutes terminals 24, is used for the copper cash welding with coil; When being welded in the utility model current transformer on the circuit board, the pin 21 of catch 20 upper parts can be directly fixed on the circuit board and weld, because terminals 24 welding that coil is and is positioned at catch 20 sides, thus the welding of coil can not be affected, thereby guarantee product quality.
Offer groove 23 on the described catch 20, the effect of groove 23 mainly is ccontaining copper cash, reduces exposing of copper cash as far as possible, also can protect simultaneously the copper cash can be not injured when the turning and the situation of broken string occurs; Wherein, this groove 23 can be offered (not shown) around the side of catch 20.
As shown in FIG., the side that described catch 20 is positioned at pin 21 has indent platform 22, the copper cash that coil is connected with terminals 24 is walked around this indent platform 22 and is connected with terminals 24, at this moment, because indent platform 22 is lower than the upper end of catch 20, so copper cash can not be affected, current transformer can steadily be fixed on the circuit board.
As shown in FIG., offer groove 23 on the described indent platform 22, be used for ccontaining copper cash, reduce exposing of copper cash as far as possible.
Described catch 20 has two, is symmetricly set on the skeleton 10, and the structure of each catch is identical, and certainly, the quantity of this catch 20 is not limit.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
