Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Refer to Fig. 1 to Fig. 4, the stamped terminals 100 of low insertion force disclosed in the utility model comprises pressing structure 10 and is connected with pressing structure 10 and supplies inserted sheet 200 to plug the connected structure 20 connected, be preferably, pressing structure 10 comprises the fin 11 and fin 12 that bend to center, be provided with the neck of interior contraction between fin 12 and connected structure 20, this neck extends contraction also by the direction of the left and right sides airfoil 12 of connected structure 20 and is formed.Connected structure 20 comprises base plate 21, left plate 22, right plate 23 and top board 24.Top board 24 and base plate 21 are spaced from each other and are arranged side by side.Particularly, in top board 24 and base plate 21, the left side of one and right side all extend one for the moving block 241 rotated along the left and right directions of connected structure 20.And one is fixedly connected with right plate 23 or left plate 22 in moving block 241, in moving block 241 another one along the left and right directions plug-in card of connected structure 20 in left plate 22 or right plate 23.Two moving blocks 241 are arranged in rows along the left and right directions of connected structure 20 and are positioned at the middle part place of top board 24 or base plate 21.Left plate 22 and right plate 23 are fixed on the another one in base plate 21 and top board 24.And base plate 21, left plate 22, right plate 23 and top board 24 4 surround a grafting chamber 25 can inserted for inserted sheet 200.When inserted sheet 200 inserts grafting chamber 25, the extruding that top board 24 or base plate 21 are subject to inserted sheet 200 is that rotating shaft is put at the direction of insertion pivot perpendicular to inserted sheet 200 with the accent increasing grafting chamber 25 with two moving blocks 241.More specifically:
Left plate 22 is provided with a boss 221, and this boss 221 is provided with a draw-in groove 222, and in moving block 241, one is specially a projection, this projection by top board 24 Left-side center extend to form and plug-in card in draw-in groove 222.In moving block 241, another one is specially a bending pin, and the height of this bending pin is corresponding with the height in grafting chamber 25.Bending pin mainly plays support and connection function.Therefore the projection of plug-in card in right plate 23 can be also set to.Two same moving blocks 241 also can be set to two symmetrical bending pin, and certain moving block 241 can also be set to the structure that other plays support and connection function.
Further, top board 24 is set to lattice structure, and this lattice structure is formed for contact-making surface 242 on of grafting chamber 25.The lattice structure of the corresponding top board 24 of base plate 21 is provided with the grid projection 26 stretched in grafting chamber 25, and the lower contact-making surface 211 that corresponding formation one confession is conflicted with inserted sheet 200.Make to realize face with the contact of inserted sheet 200 to contact, effectively increase contact point, increase ampacity further.And lattice structure effectively can improve elasticity.More preferably, lower contact-making surface 211 is the low and middle high arc contact surfaces in both sides, and corresponding upper contact-making surface 242 corresponds to the high and middle low arc contact surface in both sides.
When inserted sheet 200 inserts grafting chamber 25, in order to better correct and guide the direction of insertion of inserted sheet 200, effectively prevent contact-making surface to be out of shape, be provided with overstress sheet 27 in grafting chamber 25 anterior end and rear end.Particularly, the rear and front end place of left plate 22 and the rear and front end place of right plate 23 are provided with the overstress sheet 27 stretched in grafting chamber 25.More preferably, the overstress sheet 27 on left plate 22 is arranged in rows with the left and right directions of the overstress sheet 27 on right plate 23 along connected structure 20.
In order to prevent the excessive grafting of inserted sheet 200, connected structure 20 also comprises the retainer 28 that the direction of inserting grafting chamber 25 along inserted sheet 200 is positioned at front, grafting chamber 25, and retainer 28 is located on base plate 21.
Further, pressing structure 10 and connected structure 20 one-body molded formed by the bending of strip plate stamping.Easy to process like this, production efficiency is higher.Particularly, the side upwards bending formation left plate 22 of base plate 21, the center of left plate 22 forms a boss 221, this boss 221 has a draw-in groove 222.The opposite side upwards bending formation right plate 23 of base plate 21.Two moving blocks are specially curved pin 241 and a projection 241.Extend upward bending pin 241 also returning formation and base plate 21 are spaced from each other and the top board 24 be arranged side by side in the center of right plate 23.Projection 241 is extended in the middle part of the free end of top board 24.By in the draw-in groove 222 of this projection 241 plug-in card on boss 221, base plate 21, left plate 22, right plate 23 and top board 24 is made to be connected to surround a grafting chamber 25 can inserted for inserted sheet 200 with this.Wherein, 4 overstress sheets 27 are formed by button in the end of left plate 22 and right plate 23.Retainer 28 is for being bent into the catch of bar shaped.
By reference to the accompanying drawings, the operation principle of the stamped terminals 100 of low insertion force of the present utility model is described: when inserted sheet 200 be inserted to contact with the upper contact-making surface 242 of top board 24 time, top board 24 with two moving blocks 241 for rotating shaft, under the extruding of inserted sheet 200 and the acting in conjunction of rotating shaft, the first half of upper contact-making surface 242 is because of elastic deformation upwards pivot pendulum, the latter half of upper contact-making surface 242 is because of the downward pivot pendulum of elastic deformation, and concrete pivot pendulum direction as shown by the arrows in Figure 3.
After the insertion depth of inserted sheet 200 exceedes moving block 241, the first half of upper contact-making surface 242 is because of the downward pivot pendulum of elastic deformation, and the latter half of upper contact-making surface 242 is because of elastic deformation upwards pivot pendulum.Concrete pivot pendulum direction as shown by the arrows in Figure 4.
Compared with prior art, the utility model forms a grafting chamber 25 can inserted for inserted sheet 200 by interconnective top board 24, base plate 21, left plate 22 and right plate 23.The left side of top board 24 or base plate 21 formation two corresponding to right side moving block 241.When inserted sheet 200 inserts grafting chamber 25, there is the top board 24 of two moving blocks 241 or base plate 21 and be subject to inserted sheet 200 and extrude, then with two moving blocks 241 for rotating shaft pivot pendulum.Can constantly adjust the size of insertion force along with the insertion of described inserted sheet, effectively reduce insertion force.And add the accent in grafting chamber 25 because pivot pendulum, ensure that the real-time reliable of top board 24 and base plate 21 and inserted sheet 200 contacts, effectively increase the contact point of top board 24 and base plate 21 and inserted sheet 200, and then increase ampacity.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
