Abstract
The utility model discloses a kind of card contacts, comprises connection substrate, and the side of connection substrate is provided with the contact arm of a bending forming V-shape, forms a through hole between contact arm and described connection substrate.Contact of the present utility model is formed by the stamping-out of one piece of metal plate and bending machining, and by being formed with the contact receiving the receiving space housings support inserting card along direction of insertion, the contact arm stamping-out forming V-shape of this contact chip, the card inserted is by the contact arm being pressed in forming V-shape, make the contact arm strain of V-arrangement, and to card fixation, stable connection, retaining element is few, and cost of manufacture is low.The most important thing is, this card connector contact has anti-snagging dog, and anti-sticking is suspended to the end of contact and the advantage damaged.
Description
Technical field
The utility model relates to the connectors such as storage card, particularly a kind of card contacts.
Background technology
Rectangular electric connector of the prior art is various in style, respectively there is its feature, some electric connectors are in order to fixed contact therefor, a structural member can be assembled in the insulator, although such product structure achieves the function of fixed contact therefor, but add a part, add cost of parts and extend installation time simultaneously, too increase cost from standpoint of efficiency analysis.Some card connector contacts without anti-snagging dog function, when card insert or when extracting, card may mount the end of contact element and damage connector.
Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, provides that a kind of structure is simple, cost of manufacture is low, the card contacts of stable connection.
For solving the above-mentioned defect of prior art, the technical scheme that the utility model provides is: a kind of card contacts, comprise connection substrate, the side of described connection substrate is provided with the contact arm of a bending forming V-shape, forms a through hole between described contact arm and described connection substrate.
One as the utility model card contacts is improved, stiff end before described contact arm front end extends one, described front stiff end is connected on described connection substrate, and stiff end after described contact arm rear end extends, described rear stiff end is connected on described connection substrate.
One as the utility model card contacts is improved, and the position that described connection substrate is connected with described front stiff end and rear stiff end is equipped with a connecting groove.
One as the utility model card contacts is improved, and described connection substrate is provided with installation portion.
One as the utility model card contacts is improved, and described connection substrate is sheet metal component.
One as the utility model card contacts is improved, and described contact arm is shaping by stamping-out.
One as the utility model card contacts is improved, and the middle part width of described contact arm is greater than the width at contact arm two ends.
Compared with prior art, the utility model has the advantages that: contact of the present utility model is formed by the stamping-out of one piece of metal plate and bending machining, the contact arm stamping-out forming V-shape of this contact chip, the card inserted is by the contact arm being pressed in forming V-shape, make the contact arm strain of V-arrangement, and to card fixation, stable connection, retaining element is few, and cost of manufacture is low.The most important thing is, this card connector contact has anti-snagging dog, and anti-sticking is suspended to the end of contact and the advantage damaged.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model end view.
Reference numeral title: 1, connection substrate 2, contact arm 3, through hole 4, front stiff end 5, rear stiff end 6, connecting groove 7, installation portion.
Embodiment
Just with reference to the accompanying drawings the utility model is further described below.
As depicted in figs. 1 and 2, a kind of card contacts, comprises connection substrate 1, and the side of connection substrate 1 is provided with the contact arm 2 of a bending forming V-shape, forms a through hole 3 between contact arm 2 and connection substrate 1.When the card inserted is by the contact arm 2 being pressed in forming V-shape, make contact arm 2 strain of V-arrangement, card is subject to the elastic force effect of contact arm 2, to card fixation, and stable connection.
Preferably, stiff end 4 before contact arm 2 front end extend horizontally away, front stiff end 4 is connected on connection substrate 1, and stiff end 5 after contact arm 2 rear end extend horizontally away, rear stiff end 5 is connected on connection substrate 1.
Preferably, the position that connection substrate 1 is connected with front stiff end 4 and rear stiff end 5 is equipped with a connecting groove 6.
Preferably, connection substrate 1 is provided with installation portion 7.
Preferably, connection substrate 1 is sheet metal component.
Preferably, contact arm 2 is shaping by stamping-out.The accessory that this product uses is few, and cost of manufacture is low, easy to use.
Preferably, the middle part width of contact arm 2 is greater than the width at contact arm two ends.
Contact of the present utility model is formed by the stamping-out of one piece of metal plate and bending machining, and by being formed with the contact receiving the receiving space housings support inserting card along direction of insertion, the contact arm 2 stamping-out forming V-shape of this contact chip, the contact arm 2 of the card pressing forming V-shape inserted, make contact arm 2 strain of V-arrangement, and to card fixation, stable connection, retaining element is few, and cost of manufacture is low.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
