Abstract
The invention discloses a detachable clamping type limiting device for welding of electronic direct inserts. The detachable clamping type limiting device for welding of electronic direct inserts is characterized by comprising two clamping pieces, wherein the two clamping pieces are propped against each other oppositely; longitudinal grooves for accommodating pins are formed in a surface, which is opposite to the other clamping piece, of at least one clamping piece; at least one pair of buckles is arranged on two surfaces, which are propped against each other oppositely, of the two clamping pieces; and lower edges of the surfaces, which are propped against each other oppositely, of the two clamping pieces are chamfered. When the detachable clamping type limiting device is used, the two clamping pieces are combined in a sucking manner, so that the pins are positioned in the longitudinal groove, then the direct inserts are inserted on a PCB, are placed stably and are not liable to deflect, after welding of the direct inserts is finished, the clamping pieces are separated from each other and taken down, connection of cooling fins is not affected, height consistency is good, coplanarity of surfaces, which are in connection and contact with the cooling fins, of the pins is good, after being connected, the pins are small in stress, heat conduction efficiency is high, negative effects on performance of products are small, and later-period assembling precision is high. The detachable clamping type limiting device is simple in structure and suitable for being popularized.
Description
Technical field
The present invention relates to a kind of electronic product soldering appliance, particularly relate to the box-like stopping means of a kind of electronics direct plugging member welding detachable card.
Background technology
Along with the progress of science and technology, electronic product is day by day universal, in electronic product assembling process, the operation that is absolutely necessary is welded in solder, hyundai electronics welding is more and more higher to technological requirement, particularly early stage, welding precision was very large on later stage assembling impact, generally flange-cooled multiple power component group than what be easier to go wrong, as being connected with fin after multiple FET welding, just require higher to the regularity of FET when such early stage welds, could be located by connecting preferably, stressed just balanced, the method of current employing has two kinds, one is first bend to FET pin to form limiting section in slotting weldering, this method is stressed easy damage FET encapsulation when pin first bends, the serious inner core that also can damage affects properties of product, in addition because FET inserts the higher easy inclination of tailheaviness, postwelding righting easily damages encapsulation and pad produce difference in height, two is overlap limit casing on pin, this method limit casing cannot be dismantled, the connection of fin will be hindered when tube wall is thicker, this still awaits technological innovation and solves.
Summary of the invention
In order to the present invention that solves the problem newly provides the box-like stopping means of a kind of electronics direct plugging member welding detachable card.
The technical solution used in the present invention is: the box-like stopping means of a kind of electronics direct plugging member welding detachable card, it is characterized in that comprising the intermediate plate that two panels is close together relatively, the face that one of them sheet intermediate plate is relative with another sheet is provided with the longitudinal fluting holding pin, two faces that what two intermediate plates were relative be close together at least are provided with a pair buckle, lower edge, the face chamfering that what two intermediate plates were relative be close together.
Further, convex tendon is provided with above described two intermediate plates.
Further, described two intermediate plates are provided with the gap running through intermediate plate in longitudinal fluting lower end.
Further, be close together two faces that described two intermediate plates are relative are at least provided with a through hole.
Further, the side chamfered edges in be close together two faces that described two intermediate plates are relative.
When the present invention uses, two panels intermediate plate is engaged, make pin be in longitudinal fluting, then direct plugging member is inserted on pcb board, place stable not easily crooked, separately taken off by intermediate plate after welding, do not hinder the connection of fin, high consistency is good, contact surface coplanarity is connected good with fin, after connecting, pin stress is little, and heat conduction efficiency is high, little to properties of product negative effect, later stage assembly precision is high, and structure is simply suitable for promoting.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention decomposition view.
Fig. 2 is embodiment of the present invention overview.
Number in the figure title: 1,2 intermediate plates; 3,4 longitudinal flutings; 5,6 buckles; 7 chamferings; 8 gap.
Detailed description of the invention
The embodiment of the present invention one as shown in Figure 1, 2, the box-like stopping means of this electronics direct plugging member welding detachable card is provided with the intermediate plate 1,2 that two panels is close together relatively, the face that one of them sheet intermediate plate is relative with another sheet is provided with the longitudinal fluting holding pin, the present embodiment two intermediate plate opposite face is equipped with relative longitudinal fluting 3,4, longitudinal fluting is two right, can also arrange by one side during enforcement, longitudinal fluting quantity can be arranged according to number of pin; Two faces that what two intermediate plates were relative be close together at least are provided with a pair buckle 5,6, can be one or more pairs of during enforcement, adhesive firmness is as required selected, lower edge, the face chamfering 7 that what two intermediate plates were relative be close together, two intermediate plates are provided with the gap 8 running through intermediate plate in longitudinal fluting lower end, prevent from pushing down the formation that pad affects solder joint meniscus; First appropriate length is cut into before the present invention uses, during use, two panels intermediate plate is engaged, pin is made to be in longitudinal fluting, then direct plugging member is inserted on pcb board, place stable not easily crooked, after welding, intermediate plate is separately taken off and can be recycled, do not hinder the connection of fin, high consistency is good, is connected contact surface coplanarity good with fin, after connecting, pin stress is little, heat conduction efficiency is high, little to properties of product negative effect, and later stage assembly precision is high, the simple cost of structure is low easy to implement, is suitable for applying.
Convex tendon can being set on two intermediate plates during the invention process, for supporting encapsulation, being convenient to take off; Can being at least provided with a through hole on be close together two faces that two intermediate plates are relative, during for dismantling, ejecting opposite side with thimble; Also at the side chamfered edges in relative be close together two faces of two intermediate plates, dismounting can be separated for prying open.
Be only present pre-ferred embodiments in sum, all equivalence modifications of doing according to the application and prior art are added and are all considered as the technology of the present invention category.
