Abstract
The invention provides a cable-pressing terminal and belongs to the field of electrical connecting parts. The problem that an existing cable-pressing terminal is prone to damaging a circuit board is solved. The cable-pressing terminal comprises an insulating base and metallic reeds. Multiple insertion grooves are formed in the insulating base, and a through hole is formed in the bottom of each insertion groove and penetrates through the insulating base. Each metallic reed comprises a cable clamping part, a weld part and a middle part, wherein the cable clamping part is used for clamping a cable, the weld part is connected with the circuit board, and the middle part is used for connecting the cable clamping part and the weld part. The width of the weld parts is smaller than that of the middle parts to form stepped faces, each metallic reed is inserted into one insertion groove, the weld parts penetrate through the through holes to be exposed out of the insulating base, and the stepped faces abut against the bottom surfaces of the insertion grooves. When the metallic reeds are subjected to insertion force or pulling force, the insulating base can perform buffering on the metallic reeds, so that the circuit board is protected. The insulating base isolates the metallic reeds from the circuit board, so that interference, on the circuit board, of the metallic reeds is reduced, and transmission performance of a signal is improved.

Embodiment
Be below specific embodiments of the invention by reference to the accompanying drawings, technical scheme of the present invention is further described, but the present invention be not limited to these embodiment.
The present invention protects a kind of pressure line terminal, and concrete structure as shown in Figure 1, Figure 2, Figure 3 shows.It at least comprises insulating base 1 and metal spring leaf 2, by the structure of metal spring leaf 2 is optimized to design, can effectively improve the life-span of the wiring board that pressure line terminal connects, and also can improve signal transmission performance simultaneously.
Particularly, insulating base 1 for insulating material make for holding the base of metal spring leaf 2, this insulating material can be plastics, rubber etc.Insulating base 1 is provided with a plurality of slots 10, each slot 10 metal spring leaf 2 of can pegging graft.
Wherein, slot 10 comprises the end face of opening, four sidewalls that extend to the degree of depth, and bottom surface.On bottom surface, offer the through hole that extends through insulating base 1 outer surface, metal spring leaf 2 inserts in slot 10, and stretches into through hole and be exposed to the wiring board welding in insulating base 1 external ear and network wiring frame.
The structure of metal spring leaf 2 as shown in Figure 4, comprises thread jamming part 21, middle part 22 and weld part 23.
Wherein, thread jamming part 21 is used for the line to be accessed with outside and is connected, and comprises two identical and symmetrical card line plates in one plane side by side.The end of two card line plates links into an integrated entity by middle part 22, between two card line plates, has certain interval, thereby it is tight by wire clamp elastic deformation to occur.
In order to increase elastically-deformable restoring force, each card line plate near being especially arranged with recess 210 in the part of the close card line plate end of inner side edge on the inner side edge of another card line plate, the recess 210 of two card line plates arranges in opposite directions, form a cable clamping interface, can be convenient to line and stop in this cable clamping interface.
Meanwhile, for the ease of line, slide into cable clamping interface, at the above-mentioned inner side edge front end of each thread jamming part, be provided with corner cut 211, this corner cut 211 expands outwardly the gap between two card line plates, makes line more easily find gap and enters in gap clamped.
The middle part 22 of metal spring leaf 2 is connected between thread jamming part 21 and weld part 23,22 both sides, middle part are provided with projection with respect to card line plate lateral surface, in the middle part of this projection makes, two sides of 22 become certain camber angle to outer process with respect to the outer side edges of card line plate, this camber angle make middle part two sidewalls of 22 can with the madial wall interference fit of slot 10, thereby be closely connected with slot 10.
In weld part 23 and 22 junction, middle part, because the width of weld part 23 is less than the width of 22 joints, middle part, so Gai joint forms cascaded surface 220.When shelves weld part 23 arrives certain depth through through hole, this cascaded surface 220 can be against on slot 10 bottom surface, and it is mobile to stop weld part 23 to continue.And the side wall surface interference fit of middle part 22 dual-sides and slot 10 can stop again weld part 23 and metal spring leaf 2 along oppositely mobile.
Therefore; adopt metal spring leaf 2 of the present invention; metal spring leaf 2 is being received when inserting or pulling out active force; capital is subject to the buffering of insulating base 1 to it; make active force can not act directly on fully weld part 23 with on the wiring board that needs to be connected; thereby can protection circuit plate, improve the life-span of wiring board.
Further, as shown in Figure 2, insulating base 1 is provided with a plurality of identical slots 10, and these slots 10 equidistantly arrange successively along straight line direction, and the length direction of each slot 10 is also that the Width of metal spring leaf 2 becomes an acute angle with above-mentioned straight line.The benefit of arranging so is sideling, can reduce the width of insulating base 1, reduces volume.In addition, metal material can have certain interference effect to data-signal transmission, and insulating base 1 is by metal spring leaf 2 and wiring board isolation, can well solve interference problem, improves signal transmission performance.
Meanwhile, as seen from Figure 1, Figure 2, on insulating base 1, on the position of the middle part correspondence of each slot 10, along the direction of arranging perpendicular to above-mentioned straight line, offer square groove 13, so each square groove 13 is angled with corresponding slot 10.And take corresponding slot 10 middle parts is boundary, two madial walls of square groove 13 are divided into front and rear, and wherein, two madial wall front portions are respectively provided with a protruding block 11，Er rear portion and are provided with baffle plate 12, and this baffle plate 12 top is upward provided with opening.
Adopt square groove 13 and the slot 10 of this structure, make the insulating base 1 can compatible KRONE type wiring tool and two types of 110 type wiring tools, thereby improved the applicability of structure.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various modifications or supplement or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although more used the terms such as reed, pressure line terminal, weld part, thread jamming part herein, do not got rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present invention; They are construed to any additional restriction is all contrary with spirit of the present invention.
