Description
[technical field]
The utility model relates to a kind of electric connector terminal, particularly relates to a kind of electric connector terminal that is inserted in circuit board.
[background technology]
Along with the continuous progress of transfer of data in the electronic equipment and communication system, the density that is inserted in connector terminals is more and more higher, and also requires more and more higher to the accuracy of its butt joint.As a kind of electric connector terminal that No. 5312276 United States Patent (USP) disclosed, it is inserted in earlier in the circuit board plate hole, then docks with other electronic building brick again.Existing this electric connector terminal can see for details shown in Figure 1, and the afterbody 7 that it has the bigger holding parts of width 4 and links to each other with holding parts 4 is provided with a through hole 6 on holding parts 4.Because the holding parts 4 of this electric connector terminal offers a through hole 6, makes its elastic deformability preferable, makes holding parts 4 less thick simultaneously, strength reduction.Electric connector terminal is in the plate hole 8 that is pressed into circuit board 1 by external force the time, and its holding parts 4 is subjected to the extruding of circuit board 1 plate hole sidewall and easily bends, and makes its afterbody 7 produce crooked.Therefore, when this electric connector terminal docks with other electronic building brick again, the adverse consequences that can't correctly dock can take place then.
[utility model content]
Technical problem to be solved in the utility model is, overcomes above-mentioned the deficiencies in the prior art, provides a kind of and not only had certain elasticity, but also has sufficient intensity can not produce crooked electric connector terminal to guarantee electric connector terminal afterbody after inserting circuit board.
The technical scheme that its technical problem that solves the utility model adopts is: electric connector terminal, can electrically connect with other electronic building brick behind the break-through circuit board, it is by head, holding parts and afterbody are formed, the afterbody that stretches out circuit board can be electrically conducted with another electronic building brick, holding parts is pressed in the plate hole of circuit board, holding parts comprises two relative B sides that contact with the plate hole extruding of circuit board and two relative A sides that are adjacent, the direction of two relative upper edge, A side electric connector terminal insertion circuit boards is provided with a plurality of grooves, be formed with rib between two adjacent grooves, on two relative B sides, respectively be concaved with an elongate slot, be provided with flank in the elongate slot both sides.
In technique scheme, the A side is the plane; Each design has two grooves, two groove center symmetries on two relative A sides.
The width of holding parts is greater than the diameter of the plate hole on the circuit board.
Elongate slot is positioned at the middle position of B side.
The beneficial effects of the utility model are: adopt the electric connector terminal of said structure and shape, the elasticity the when elongate slot that designs on two relative B sides can strengthen holding parts and contacts with the circuit board plate hole; Rib on two relative A sides can strengthen the intensity of electric connector terminal, makes electric connector terminal unlikely generation after inserting circuit board crooked, is beneficial to the electric connector terminal afterbody and is inserted into smoothly in other electronic building brick.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is that the existing electric connector terminal relevant with the utility model is inserted into the schematic diagram in the circuit board;
Fig. 2 is a perspective view of the present utility model;
Fig. 3 is the cutaway view of Fig. 2 along the A-A direction;
Fig. 4 is the schematic diagram after the utility model inserts the plate hole of circuit board;
Fig. 5 is the cutaway view of Fig. 4 along the B-B direction.
[embodiment]
Referring to Fig. 2, Fig. 3 and Fig. 4, the described electric connector terminal 2 of present embodiment, can electrically connect with other electronic building brick behind the break-through circuit board 21, it is by head 23, holding parts 24 and afterbody 25 are formed, the afterbody 25 that stretches out circuit board 21 can be electrically conducted with another electronic building brick, holding parts 24 is pressed in the plate hole 22 of circuit board 21, holding parts 24 comprises two relative B sides 27 that contact with plate hole 22 extruding of circuit board 21 and two relative A sides 26 that are adjacent, the arcuation surface of B side 27 for having certain curvature, the curvature of this curvature and plate hole 22 is basic identical; A side 26 is the plane, on the direction of two relative A sides, 26 upper edge electric connector terminals, 2 insertion circuit boards 21, respectively be provided with two grooves 29, two groove 29 center symmetries, between two grooves 29, be formed with rib 30, on two relative B sides 27, respectively be concaved with an elongate slot 31, elongate slot 31 is positioned at the middle position of B side 27, forms flank 28 respectively in elongate slot 31 both sides, and this flank 28 can produce certain distortion when electric connector terminal 2 inserts the plate hole 22 of circuit board 21.
Schematic diagram when Fig. 4 is subjected to external pressure to be pressed into the plate hole 22 of circuit board 21 for electric connector terminal 2, the width of the holding parts 24 of electric connector terminal 2 is greater than the diameter of the plate hole on the circuit board 21 22, under external force, the holding parts 24 of electric connector terminal 2 is subjected to the extruding of plate hole 22 sidewalls of circuit board 21, after certain strain takes place, be immobilizated in the plate hole 22 of circuit board 21 thereby interfere, its afterbody 25 stretches out outside the plate hole 22, and can dock with other electronic building brick.
Fig. 5 is the cutaway view of Fig. 4 along the B-B direction, when being pressed in the plate hole 22 of circuit board 21, electric connector terminal 2 produces certain elastic deformation, elongate slot 31 on the B side 27 can strengthen the elastic deformability in when contact, thereby unlikely electric connector terminal 2 and plate hole 22 is caused damage.Groove 29 can increase the elastic deformability of holding parts 24, can prevent that also electric connector terminal 2 from damaging electric connector terminal 2 and plate hole 22 when inserting circuit board 21, rib 30 can increase the intensity of holding parts 24, with prevent by groove 29 bring because of undercapacity makes when being pressed into electric connector terminal 2 crooked because of pressurized causes afterbody 25 to produce, the afterbody 25 that helps electric connector terminal 2 accurately docks with other electronic building brick.
