Abstract

The utility model relates to a terminal positioning plate with many radiation claws, which is an integral tabular body and has better tensile force and clamp force. The utility model is characterized in that an upright cylinder shaped buckle section is arranged; the buckle section is provided with taper grooves which form many radiation claws in the cylinder wall of the buckle section; the lower part near the claws is provided with outward expanding ridges that extend downward to the end; thus, the utility model is easily and stably to be combined together with a circuit board while keeping the well-clamped buckle positioning function.

Description

Terminal positioning plate with multi-radiation grab

The utility model relates to the structure of terminal position in circuit board, and this structure is the terminal position sheet with a plurality of radiation pawls.

Because computer, science and technology such as electronics and motor is maked rapid progress, the most of device (PC plate) on circuit board of electrical equipment or electronic product, exporting the function on the host circuit board or fast breath to another parts executes the task, export data to monitor or printer as computer motherboard, the machine main frame moves grinding or roll compacting etc. with data or instruction output execution ... all need to solve main frame and the machine of paying or function follower combining and the disengaging problem between the two, so terminal becomes important role.

Referring to Fig. 1: terminal 5 is designed or directly is positioned the edge of circuit board usually, and jack 32 energisings of inserting circuit end on the circuit board 3 with its pin 52, to simplify board circuit to the lead-in wire between terminal, but because of effects limit and assemblings such as circuit board materials, cost consideration such as decomposition, can't adopt welding or the solid method of spiral shell at circuit board corresponding terminal place, so generally adopt and be provided with reservation through hole 31 in the appropriate location of circuit board 3, make the positioning clamping pin 13 of the attached work in both sides on the terminal 5 can run through this preformed hole 31 and the clamping location, referring to Fig. 2,4, tradition terminal position sheet 1 is designed to central slot 12 to the lower end, and be divided into two card bases 13, be provided with sincere stops 14 in addition in card base 13 nearly lower ends, the plastic tension force of borrowing fluting 12 to give card base 13, make terminal position sheet 1 insert the preformed hole 31 of circuit board 3 after, can be buckled on the circuit board 3, and terminal 5 is positioned on the circuit board 3, and connects with the extended line terminal 4 of the actuator of other end and to realize output functions.

Though, traditional terminal position sheet 1 has solved terminal 5 Fast Installation, decompose and orientation problem, but the contact-making surface of clamping circuit board 3 is narrow and small, the position of P1 as shown in the figure, referring to Fig. 4,6 as can be known the card base 13 of spacer 1 to be clamped in the cross-sectional width W of hole 31 parts of circuit board 3 very little, two card bases 13 are in-line or on same plane, so behind its location, the fore-and-aft direction of spacer 1 has the situation of rocking to take place, and has influenced the superperformance that electrical equipment is in contact with one another.

The purpose of this utility model is to provide a kind of buckle contact point P2(of spacer to see Fig. 7), on the very average garden that is distributed in week, make its contact area wider, and cooperate the tension force of its enhancing and obtain the good positioner of a stablizing effect, provide a kind of one-body molded terminal position sheet, the terminal position sheet that non-other two-chip type combination person can compare with a plurality of radiation pawls.

The purpose of this utility model is to realize like this; A kind of terminal position sheet 2 that is positioned on the circuit board with a plurality of radiation pawls, one-body molded is the flat body, has a vertical surface 21, central authorities are provided with a through hole 22, after a bending, has a horizontal plane 23, and be than leptoprosopy 24 in front end, it is characterized in that: after bending, be a upright garden tubular clamping part 25 again, this clamping part 25 and above-mentioned than 24 formation of leptoprosopy, one gap 251, and suitably slot 252 on the garden tubular clamping part 25 apart from offering taper, make to form a plurality of radial pawls 253 on clamping part 25 barrels, the lower end of close pawl is provided with the protuberance 254 that expands outwardly, and extends convergent tail end 255 to the lower end.

Advantage of the present utility model is: garden tubular clamping part is provided with the taper fluting, make and form a plurality of radial pawls on the clamping part barrel, when clamping part and circuit board fasten, strong tension force and a plurality of radiation pawls that are uniformly distributed on the week of preformed hole garden on it, make stable the combining of terminal position sheet and circuit board, improved the superperformance that electrical equipment is in contact with one another.

Concrete structure of the present utility model further specifies by following examples and accompanying drawing thereof:

Fig. 2: be traditional terminal position sheet stereo appearance figure

Fig. 3: be the utility model terminal position sheet stereo appearance figure

Fig. 4: be the schematic diagram before traditional terminal position sheet location

Fig. 5: be the schematic diagram before the utility model terminal position sheet location

Fig. 6: the schematic diagram that is positioned circuit board for traditional terminal position sheet

Referring to Fig. 3: a kind of terminal position sheet 2 that is positioned on the circuit board with a plurality of radiation pawls, one-body molded is the flat body, has a vertical surface 21, central authorities are provided with a through hole 22, after a bending, have a horizontal plane 23 and be than leptoprosopy 24 in front end, it is characterized in that: after bending, be a upright garden tubular clamping part 25 again, this clamping part 25 and above-mentioned than 24 formation of leptoprosopy, one gap 251, and suitably slot 252 on the garden tubular clamping part 25 apart from offering taper, make and form a plurality of radial pawls 253 on clamping part 25 barrels, lower end near pawl is provided with the protuberance 254 that expands outwardly, and extends convergent tail end 255 to the lower end.

During use, vertical surface on the terminal position sheet 2 21 is placed the preformed groove 51 of terminal 5 left and right sides, and together it is pushed in the preformed groove 51 with a block 16 that is provided with screwed hole 161, (screwed hole 161 of this block 16 can allow solid bar 41 spiral shells of the spiral shell of extended line terminal 4 connect firmly this two-terminal 5 of knot, 4), and with in the through hole 53 on garden tubular clamping part 25 penetrating terminals 5, and clamping part 25 is pushed the preformed hole 31 phase buckles of circuit board 3, meanwhile, pin 52 on the terminal 5 also inserts energising in the circuit board 3 circuit end jacks 32 simultaneously, before reaching, after, a left side, the right good snaps into position function of clamping that all keeps improves the superperformance that electrical equipment is in contact with one another.
