Description
Technical field
The utility model is related to field of electrical components, relates particularly to a kind of plug-in element suitable for Reflow Soldering.
Background technology
It is general to be welded component on circuit boards using wave-soldering or reflow soldering process in electronic product production.Mesh
Preceding wave-soldering is mainly welding plug-in element, and the welding sequence of plug-in element is：First in back of circuit board dispensing, paster, baking
It is dry, then manually insert plug-in element in circuit board front, cross wave-soldering, artificial repair welding, manual testing；Reflow Soldering is welding patch
Piece element, the welding sequence of surface mount elements is：Brush tin cream, patch surface mount elements, paster, Reflow Soldering, board excessively are tested automatically.Thus
It can be seen that, the complex procedures of solder wave process, recruitment cost are high, efficiency is low, board input resource is more, are unfavorable for realizing whole-process automatic
Change；And reflow soldering process precision height, efficiency high, full-automation.But, surface mount elements are expensive, improve cost.
Utility model content
In view of this, in view of the shortcomings of the prior art, the utility model is intended to provide a kind of simple in construction, cost low
Suitable for the plug-in element of Reflow Soldering.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of plug-in element suitable for Reflow Soldering, including component body and two pins, the pin are fixed on the member
The lower end of part body, the pin is one horizontal part of bending formation, the water at 2mm-10mm in the height of distancing element body
The pin in flat portion is that bending is formed down a vertical portion at 1mm-5mm in horizontal length.The program passes through drawing plug-in element
Pin for 2mm-10mm place's bendings forms horizontal part in the height of distancing element body, and the pin of horizontal part is 1mm- in horizontal length
Bending is formed down vertical portion at 5mm, so that on circuit boards after brush tin cream, the vertical portion of the plug-in element can pass through machine
Platform is automatically inserted into the jack of circuit board, and the horizontal part lower surface of pin is then in close contact with the pad on circuit board, is together led to
Cross Reflow Soldering board so that plug-in element pin is closely coupled with pad, reach the effect as surface mount elements.Pin away from
Height from component body is bending at 2mm-10mm, can be avoided when height is less than 2mm, pin, can be right in reforming process
Component body causes mechanical damage；When height is more than 10mm, in process of production, crank is easily welded element
Bad situation.The pin of horizontal part is that 1mm-5mm goes out bending in horizontal length, can be avoided when horizontal length is less than 1mm, tin
The contact area of cream and pin is too small, and not prison welding is solid；When horizontal length is more than 5mm, element in process of production, can also go out
The phenomenon of existing crank.
Preferably, the two pins are towards the opposite inside bending in direction, and the pin after pin bending is smaller than pin
Conventional pin spacing.
Preferably, the two pins outside bending in the opposite direction, the pin spacing after pin bending is more than pin
Conventional pin spacing.
As shown from the above technical solution, the beneficial effects of the utility model are：
A kind of plug-in element suitable for Reflow Soldering of the present utility model, pin level is formed by carrying out bending to pin
Portion and pin vertical portion so that the plug-in element can realize the reflow soldering process that is applicable to as surface mount elements, structure
Simply, board automated production is realized on the premise of cost is not increased.
