Description
Technical field:
The present invention relates to the adapter technique field, particularly a kind of linear power adapter.
Background technology:
The civil power importation of conventional linear power supply is the input of drawing Transformer Winding on the traditional transformer skeleton with soft electric leads, is welded on the input plug of outer casing of power supply again, and need overlaps the isolating shrinkable casing protection in the welding position.Its specific practice: after the traditional transformer skeleton winds the line bag, earlier with behind the insulating tape bag layer 2-3, temperature protective device and soft electric leads are placed on line respectively wrap with insulating tape and fast crust paper and fix, behind the end of a thread kinking scolding tin, with insulating tape and fast crust paper the end of a thread insulation is fixed again; During the assembling of linear power supply product; on input lead, respectively be inserted in one section isolating shrinkable sleeve pipe; after the soft electric leads exposed junction of transformer the end of a thread pierced into welding hole and firm welding on the outer casing of power supply input plug respectively, the isolating shrinkable sleeve pipe is moved to the welding position shrink and pack tightly with the protection plumb joint.Problem and shortcoming that the traditional transformer skeleton exists: 1. raw material of using: soft electric leads, insulating tape and fast crust paper etc. more; 2. complex process, need are with artificial many; 3. product can't ensure product quality because of its complex process in process of production.Material cost and cost of labor that above 1-2 item directly influences product all can't reduce, and can't enhance productivity and ensure product quality because of its complex process.
The temperature protective device of transformer is an important component part in the transformer device.It must stretch into the coil inside depths, could sense the variation of winding temperature exactly, so that transmit induced signal and realize temperature controlling.Temperature protective device on traditional transformer framework is to place in the production process after coiling; it is that temperature protective device is placed in the transformer framework primary coil groove; on temperature protective device, coat insulating tape again, so that charged on the temperature protective device goes out stitch and winding is isolated with certain thickness and length.Yet; this structure can cause temperature protective device to be difficult to sense accurately, reliably the temperature of Transformer Winding because of the heat-blocking action of insulating tape; so be easy to occur the too high phenomenon of winding temperature; and; temperature protective device can not sensed variation of temperature in time because of the existence of insulating tape yet, may produce the Electrical Safety problem thus.Simultaneously, the winding of insulating tape must rely on one special operation and realize, the corresponding processing cost that improved, and coating has certain randomness.
In addition, traditional transformer framework generally is to place the insulation gummed paper to separate lead-in wire and winding layers in the transformer framework end in winding structure, to prevent causing the coil interlayer short circuit because of the insulating barrier of lead-in wire being destroyed in the coiling process; And the end of the primary coil of this transformer framework and secondary coil has all added wire casing, though also make coiling and outlet all guarantee the safe distance of insulation, but its coiling is irregular, even in improved structure afterwards, on transformer framework, opened a groove than broad, but also, lay out the coil that comes and also be difficult for smooth because this local no plastic cement blocks the coil winding displacement; Also have because it need paste insulation gummed paper etc., increased additional process in process of production, also be unfavorable for processing
Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, the spy provides a kind of linear power adapter, mainly the technical problem of Xie Jueing be that the complex process, production efficiency of traditional transformer skeleton is low, product quality can't ensure, how with raw material and processing cost height.At the above-mentioned defective of prior art, the present invention designs a kind ofly can simplify production technology, enhance productivity, again can be less with raw material and cut down finished cost, ensure the transformer framework of product quality.
For achieving the above object; the present invention adopts following technical scheme: a kind of linear power adapter; it comprises upper shell; lower house; connect plug; support body; iron plate; the support body protective sleeve; the protection buckle closure; coiling link post; outlet terminal; support body is provided with the iron core hole; the primary coil groove; the secondary wire ring recess; support body is provided with the power connecting column slot near the lower surface of primary coil groove; be provided with power connecting sheet in the power connecting column slot; be provided with a coiling link post in the front side of primary coil groove; side at the primary coil groove is provided with a monolateral domatic platform; the platform inwall offers a slot of laying temperature protective device; between individual power connecting column slot, offer a slot inlet that is used to put into this temperature protective device on the support body; one end of primary coil groove offers oblique trunking; the slot porch offers wire casing; the support body protective sleeve is socketed on the support body; protection buckle closure and support body protective sleeve snapping connect plug and are connected with lower house, connect plug and insert in the power connecting column slot by contact pin.
Described coiling link post is located at the tail end of oblique trunking;
Offer an above outlet terminal on the sidewall of described secondary wire ring recess;
Described power connecting column slot offers trough;
Described support body protective sleeve is provided with buckle, and the protection buckle closure is provided with hole clipping, boss;
Described power connecting column slot is a circular socket holes, and corresponding contact pin is cylindrical.
