Description

Terminal material belt

[technical field]

The utility model relates to a kind of terminal material belt, and especially a kind of to protect terminal disc to furl when material terminal indeformable and save the terminal material belt of material.

[technical background]

Usually install a plurality of conducting terminals in the electric connector, each conducting terminal not only shape is same or similar mostly, and it normally is the systematicness arrangement in electric connector.For the production that makes conducting terminal, follow-up plating and assembly work can realize high efficiency automation, in the production of electric connector, adopt the strip of metal sheet usually, stamp out the intermediate products that conducting terminal reaches the strip combining form that is connected with conducting terminal in the progressive press tool mode, use the carrying conveying of strip and plating and the assembly work that positioning action is carried out automation then.

No. 362635 patent of the novel patent of TaiWan, China disclosed a kind of packaging structure of existing terminal material belt; it includes a coiled terminal material belt and just is coated on strip; the insulating material on back of the body two sides; on strip except that including some arranged terminals; be extended with strip one time at the strip opposite side; on inferior strip corresponding to terminal before; protrusion position, back is all protruded with a protection support arm and is conflicted on insulating material; the length of this protection support arm is approximately than before the terminal; back protuberance height is long; the end of each root protection support arm slightly is bent into a blocking surface; like this; the protection support arm can bear external force in advance, and the protrusion position that makes terminal is in packing; carrying or be difficult for causing the external force extruding when depositing and be out of shape.

Yet the existence of inferior material-strap structure has increased the width of material, and the material that need buy enough width when therefore purchasing could satisfy the setting of this structure, and strip just becomes waste product after fractureing, waste material so not only, but also increased production cost.

China's utility model patent 201122788Y patent has disclosed a kind of terminal material belt combination to above-mentioned technological improvement, the strip that this terminal material belt combination comprises plurality of conductive terminals and connects conducting terminal.This terminal is provided with a protuberance at least.This strip extends with the convergence part of splicing ear and from the extension of base portion opposite side by base portion, from base portion one side to be formed with the protection arm of protection terminal protuberance.

Though the combination of above-mentioned terminal material belt is not provided with time strip, but still is provided with the protection arm in base portion one side, thus need only to have reduced the width of buying material to a certain extent, and also strip fractures and just becomes waste material afterwards, is unfavorable for reducing production costs.

Be necessary to provide a kind of improved terminal material belt in fact, to overcome the defective of above-mentioned terminal material belt.

[utility model content]

The technical problem that the utility model solved provides a kind of terminal material belt that can protect terminal, and this terminal material belt can reduce the terminal production cost.

In order to solve aforementioned technical problem, the utility model provides a kind of terminal material belt, it comprises pilot tape and is connected in plurality of terminals on the pilot tape, pilot tape comprises flat matrix, matrix is provided with the location hole of arranging along the pilot tape bearing of trend, and terminal protrudes from the plane at matrix place, wherein, described matrix is provided with support arm in the location hole edge side to protruding out, the distance that the distance that this support arm extends laterally from matrix protrudes out from the matrix side direction greater than terminal.

Compare with correlation technique, position of positioning hole on support arm of the present utility model and the matrix is corresponding, support arm is that the location hole edge from matrix extends, can utilize the blanking of moulding location hole to come the moulding support arm, therefore not only the width that the waste material that produces is used but also can reduces terminal material belt can be produced, thereby the cost of terminal material belt can be reduced.

[embodiment]

Consult Fig. 1 to shown in Figure 2, the utility model is a kind of terminal material belt, this terminal material belt comprises plurality of terminals 12 and connects the pilot tape 11 of this terminal 12 that terminal 12 is contained in and is used to electrically connect chip module (not shown) and printed circuit board (PCB) (not shown) in the electric connector.

Pilot tape 11 comprises flat matrix 110, and matrix 110 is elongated, is extended with connecting portion 111 in matrix 110 1 sides, and connecting portion 111 is positioned at same plane with matrix 110.Matrix 110 is provided with location hole 112, and this location hole 112 is arranged in a row along matrix 110 bearing of trends, in order to locate and to draw terminal material belt during fabrication.Location hole 112 comprises circular hole 1121 that plays the role of positioning and the resettlement section 1120 that is communicated with circular hole 1121.Matrix 110 is provided with support arm 113, this support arm 113 is 90 degree angles from location hole 112 edge sides to protruding out with matrix 110, and support arm 113 comprises from matrix 110 and extends into the kink 1130 of resettlement section 1120 and the support portion 1131 that is connected with kink 1130.

Terminal 12 comprises main part 120, from the weld part 123 of main part 120 lower ends bendings and the elastic arm 124 that extends from main part 120.Main part 120 comprises first main part 121 that is connected with connecting portion 111 and second main part 122 that is bent to form from first main part, 121 sides, and described elastic arm 124 extends upward from second main part 122.First main part 121 is positioned at same plane with matrix 110, and and the connecting portion 111 of matrix 110 between have top broken string 13.Vertical bending forms described weld part 123 from first main part, 121 lower ends.Described weld part 123, second main part 122 and elastic arm 124 protrude from the plane at matrix 110 places.

In the utility model; the distance that support arm 113 extends laterally from matrix 110 protrudes out the distance of matrix 110 greater than terminal 12 side direction; represent distance between support arm 113 and the matrix 110 as L line among Fig. 3; promptly along on the direction perpendicular to matrix 110; this distance protrudes out the height of matrix 110 greater than the elastic arm 124 of terminal 12; when coiling rewinding, support arm 113 can bear external force in advance like this, and the projection of protecting terminal 12 to protrude from matrix 110 is not subjected to the crimp of external force.

Figure 4 shows that support arm 113 bending antepositions are in the terminal material belt view on plane, matrix 110 place or a view in the terminal material belt forming process.Terminal material belt of the present utility model is moulding by the following method: earlier terminal material belt is carried out punching press, punching press forms terminal 12, location hole 112 and is contained in the lamellar body as support arm 113 in the location hole 112, and is promptly shown in Figure 4; Secondly these lamellar body bending 90 degree are formed the support arm 113 of protection terminal 12.

Support arm 113 of the present utility model is roughly corresponding with the shape of location hole 112, this support arm 113 is that the blanking bending that utilizes punching press to form location hole 112 forms, not only the width that the waste material that produces is used but also can reduces terminal material belt can be produced, thereby the cost of terminal material belt can be reduced.

Below only be preferred embodiment of the present utility model, other any improvement conversion of being done on the present embodiment basis also should not break away from the technical solution of the utility model.
