Abstract
A connection terminal comprises: a first arm and a second arm which are integrally formed, wherein the first arm and the second arm are configured to be formed into a substantially U shaped or V shaped structure; and a connecting portion extending from one side of the second arm towards the first arm, wherein a distal end of the connecting portion substantially perpendicularly bends and attaches to the outer side of the first arm to form a pressure cover plate, at least one separator is arranged between the pressure cover plate and the outer side of the first arm, and a preset distance (D) is preset between the pressure cover plate and the outer side of the first arm. The separator is arranged between the pressure cover plate or one force arm of a connection terminal, thus a certain gap is present between the pressure cover plate and one force arm of the connection terminal, and an electroplating liquid is ensured to enter into the inner surfaces between the pressure cover plate and one force arm of the connection terminal.
Description
Technical field
The utility model relates to a kind of electric connector, particularly, relates to a kind of two splicing ears between the electronic device that are connected.
Background technology
In electronic equipments such as the for example mobile phone with printed circuit board (PCB) (PCB), various portable player, digital camera and video camera, GPS device, PC, need printed circuit board (PCB) be electrically connected with the for example electronic device of another printed circuit board (PCB), motor, antenna, microphone or loud speaker and so on through splicing ear usually.
Fig. 1 utilizes splicing ear 200 to be electrically connected the schematic perspective view of the application example of two printed circuit board (PCB)s 300 in the prior art.Fig. 2 is the schematic perspective view of this splicing ear 200 of the prior art.Fig. 3 is the schematic perspective view that is used to form the preformed metallic plate of splicing ear 200.Splicing ear 200 comprises: the first arm 201 and second arm 202 and the connecting portion 203 that are used for being electrically connected to respectively the electric contact of two printed circuit board (PCB)s 300.Wherein, the first arm 201 and second arm 202 are roughly U-shaped or V-arrangement, and connecting portion 203 extends to the first arm 201 from second arm 202, and the far-end of connecting portion 203 is generally perpendicularly crooked and abut in the outside of the first arm 201, to form pressure cover plate 205.In addition, splicing ear 200 also comprises the support portion 204 that extends to the first arm 201 inboards from second arm 202.
In splicing ear 200, pressure cover plate 205 applies precompression to the first arm 201, and to limit the distance between the first arm 201 and second arm 202, because the existence of precompression, pressure cover plate 205 closely abuts in the outside of the first arm 201.Usually, need be in the outside nickel plating of splicing ear 200, to satisfy the requirement of environmental testing.But because pressure cover plate 205 closely abuts in the outside of the first arm 201, nickel plating solution is difficult to get into both inner surfaces, and some environmental testings of the feasible splicing ear product of processing can't pass through.
In order to guarantee that inner surface can be plated to nickel; A solution is; Blanking (blanking) operation of making splicing ear and bending operation are separately carried out; Both subpunch was depressed material and was formed metallic plate roughly as shown in Figure 3, afterwards this metallic plate was electroplated, and was bent into splicing ear as shown in Figure 2 200 at last again.But, adopt this scheme not only need carry out two cover diels of blanking and bending operation, and before the per pass operation, need the adjustment operating equipment, increased man-hour and manufacturing cost.Another kind of solution is, at first the bulk metal plate of making splicing ear electroplated in advance, and the splicing ear product is processed in bar stock cutting by punching, bending then.Though this scheme can be practiced thrift a cover diel, electroplate the process of whole metallic plate in advance and relatively waste gold and nickel, increased electroplating cost.
