Abstract
The utility model provides a metal stud bolt used for connecting PCBs, which comprises a columnar connecting base and an elastic end disposed at one end of the connecting base. The elastic end comprises an annular groove and an elastic annular supporting portion with a conical chamfer angle and a cross notch, and the elastic annular supporting portion is connected with the annular groove. As the elastic end of the stud bolt has certain elasticity, the elastic end of the stud bolt can be assuredly inserted in a PCB hole under smaller inserting force when the diameter of an opening hole on a PCB is slightly smaller than the outer diameter of the elastic end, and the elastic end tightly clings to the wall of the PCB hole assuredly. As the stud bolt has certain pre-tightening force after being inserted in the PCB hole, the stud bolt can be fast soldered in a wave soldering manner.
Description
Technical field
The utility model relates to a kind of metallic stud, relates in particular to be used for the double-screw bolt that the telecommunications product is used for fixing and is connected multilayer board (Printed Circuit Board, abbreviation pcb board).
Background technology
Connect the mode that supports at present between the plate of multi-layer PCB board commonly used and mainly contain following two kinds:
First kind is to adopt two ends to have the working of plastics jockey of elastic construction, and two-layer pcb board is fixed up and down.Two-layer pcb board johning knot composition as shown in Figure 1 comprises working of plastics jockey 1, and this working of plastics jockey comprises two elastic construction ends 11 (comprising elastic tip neck 111 and elastic tip shell fragment 112); Upper strata pcb board 2, lower floor's pcb board 3, PCB perforate 4.This connected mode because material is engineering plastics, and quality is softer, and need cause excesssive gap between elastic tip neck and PCB perforate with elastic tip shell fragment and elastic tip neck simultaneously by the pcb board perforate.Therefore bonding strength low, connect unreliable, can not satisfy grounding requirement, loosening or obscission appear at strenuous vibration or when falling, equipment is broken down.And the installing space that requires is bigger, and is limited a lot.
Second kind is that the tapped double-screw bolt in employing two ends adds screw or band externally threaded double-screw bolt in two ends adds nut, and perhaps adopting upper end as shown in Figure 2 is that the internal thread lower end is that externally threaded double-screw bolt connects two-layer pcb board.Comprise nut 1, double-screw bolt 2, screw 3, upper strata pcb board 4 among Fig. 2, lower floor's pcb board 5.The manner all will adopt the program that double-screw bolt need be fixed because any end is installed earlier, so install inconvenient, efficiency of assembling is extremely low, need special tooling to cooperate installs, fixing or when taking down the screw of the other end or nut, joint pin may spin together, causes can not getting any more.
Therefore, be necessary to invent a kind of jockey of pcb board, thereby solve the problems of existing two kinds of connected modes.
The utility model content
The utility model technical issues that need to address provide a kind of metallic stud of installing, locate, welding be convenient to, and solve the deficiency that jockey exists between above-mentioned two kinds of existing multi-layer PCB board plates.
For achieving the above object, the utility model provides a kind of metallic stud that is used for the connection PCB plate, comprise the elastic ends that a column connects base portion and is arranged at this connection base portion one end, it is characterized in that described elastic ends comprises circular trough and the elastic annular support portion that has taper chamfering and cross breach that is connected with this cannelure; Described cannelure has the cross breach identical with the elastic annular support portion.Described circular trough is connected base portion and links to each other with column; Described column connection base portion has internal thread away from the another one end of elastic ends.
The beneficial effects of the utility model are and since be connected between the PCB multi-layer sheet in the equipment application more and more widely, the utility model satisfies the various performance requirements of equipment comprehensively and produces the requirement of assembling fast; Can greatly improve equipment performance and efficiency of assembling, reduce product cost.

Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated.
The metallic stud generalized section of the utility model embodiment is referring to Fig. 3.The utility model is used for connection PCB sheetmetal double-screw bolt, comprise the elastic ends 2 that a column connects base portion 1 and is arranged at these connection base portion 1 one ends, described elastic ends 2 comprises circular trough 21 and the elastic annular support portion 22 that has taper chamfering 221 and cross breach 222 that is connected with this cannelure 21.Described circular trough 21 is connected base portion 1 and links to each other with column.It is 1: 2 that the taper chamfering 221 of described elastic annular support portion 22 is closed at radial and axial length ratio.Described column connection base portion 1 has internal thread away from the another one end 3 of elastic ends.
Because elastic ends 2 has cannelure 21, and the annular support part 22 of elastic ends 2 and cannelure 21 have cross breach 222, and elastic ends 2 is a hollow, therefore elastic ends 2 possesses certain elasticity, still under little insertion force, just the elastic ends 2 of double-screw bolt can be inserted in the pcb board perforates when perforate on the assurance pcb board is slightly less than elastic ends 2 external diameters, be guaranteed that elastic ends 2 and pcb board hole wall are close together.Because double-screw bolt has certain pretightning force after inserting, and has guaranteed that double-screw bolt can pass through the wave-soldering rapid welding.And because elastic ends 2 has circular trough 21, cross breach 222, make a large amount of scolding tin to go deep into PCB hole inwall by these ducts, make the contact area of scolding tin and pcb board increase greatly, and have only some scolding tin in surface, referring to Fig. 4 stud welding design sketch unlike common device welding.Increased the fastness of welding back double-screw bolt like this, guaranteed that double-screw bolt can not become flexible when the double-screw bolt cylindrical base is screwed into screw away from the other end of elastic ends to spin.When stud welding just can have been installed one deck pcb board after on the pcb board, assembling is just very simple like this, with the corresponding hole site alignment stud screw of upper strata pcb board, with manually or electric screwdriver install screw can be referring to the assembling design sketch of Fig. 5.So just do not worry that double-screw bolt and then spins when assembling or dismounting upper strata pcb board.
The double-screw bolt stereogram of the utility model one embodiment is seen Fig. 6, and it is cylindrical that its column connects base portion, and it is cylindrical that column connects base portion; And its column connection base portion is threaded circle in the band away from an other end of elastic ends.
The double-screw bolt stereogram of another embodiment of the utility model is seen Fig. 7, and its column connects base portion and is prismatic; And its column connection base portion is the polygon that has internal thread away from an other end of elastic ends.
Double-screw bolt of the present utility model can adopt metal material processing such as copper material, steel, aluminium to form.Because being applied in the present equipment of connecting between plate used more and more widely, the utility model combines the advantage of at present popular various settling modes, can satisfy various performance requirements of equipment and quick requirement of producing assembling comprehensively.Can greatly improve equipment performance and efficiency of assembling, reduce product cost, improve the quality of products.
