This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No. 201220080560.9 filed in P. R. China on Mar. 6, 2012, the entire contents of which are hereby incorporated by reference.
Some references, if any, which may include patents, patent applications and various publications, may be cited and discussed in the description of this invention. The citation and/or discussion of such references, if any, is provided merely to clarify the description of the present invention and is not an admission that any such reference is “prior art” to the invention described herein. All references listed, cited and/or discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference.
The present invention relates to an electrical connector, and more particularly to an electronic card connector having a cover capable of popping up automatically.
Currently in the industry, a common electronic card connector is soldered on a circuit board, and includes an insulating body, a plurality of terminals disposed within the insulating body, and a cover horizontally covering on the insulating body. Two sides of the insulating body are disposed with two fastening portions and a pivoting portion respectively. The cover is capable of being opened or closed relative to the insulating body about the pivoting portion. Two sides of the cover are correspondingly disposed with two locking portions locking the fastening portions and a sliding slot sliding along the pivoting portion respectively. Before the electronic card is inserted into the insulating body, the operator needs to open the cover with hands, place the electronic card, and then push the cover backward, so that the locking portion locks the fastening portion. When the electronic card needs to be taken out, the cover is pushed forward, so that the locking portion unlocks the fastening portion, and at this time, the operator also needs to open the cover, and then take out the electronic card.
As electronic products develop towards light weight, small and thin structures, the electronic card connector has a small structure, a small distance exists between the cover and the circuit board, so that the operator when intending to open the cover has to put fingers between the cover and the circuit board and apply a force to open the cover, which is inconvenient and easily causes injuries of the fingers during operation.
Therefore, a heretofore unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.
In one aspect, the present invention is directed to an electrical connector, which is easy to operate and safe in operation.
In one embodiment, an electrical connector includes: a base, disposed with at least one fastening portion and at least one pivoting portion, a cover, covering on the base, disposed with at least one locking portion correspondingly locking the fastening portion, and capable of being opened or closed relative to the base about the pivoting portion, and at least one elastic member, pressing against the base, in which when the locking portion unlocks the fastening portion, the elastic member pops up automatically due to elasticity, so that an operating space is formed below the cover to allow an operator to open the cover.
As compared with the related art, the present invention, among other things, has the following beneficial effects.
The elastic member presses against the base, and when the locking portion unlocks the fastening portion, the elastic member pops up automatically due to elasticity, so that an operating space is formed below the cover to allow an operator to open the cover with hands, which facilitates operation and does not cause injuries of the fingers, thereby ensuring safe use.
These and other aspects of the present invention will become apparent from the following description of the preferred embodiment taken in conjunction with the following drawings, although variations and modifications therein may be effected without departing from the spirit and scope of the novel concepts of the disclosure.

Referring to
The base 1 includes an insulating body 10 and a plurality of terminals 11 disposed within the insulating body 10. The insulating body 10 has a middle part 12 and two side arms 13 located at two sides of the middle part 12. The middle part 12 is disposed with a plurality of receiving slots 121. Each of the side arms 13 is disposed with two fastening portions 131. The fastening portion 131 is a step-like projecting portion. In other embodiments, each of the side arms 13 may be disposed with a fastening portion 131 located at the front end of the side arm 13, and the fastening portion 131 may be configured in other shapes. Each of the side arms 13 is disposed with a reserved slot 132 adjacent to the fastening portion 131, and a pivoting portion 133 disposed at a rear end of the side arm 13. The pivoting portion 133 is a pivot shaft protruding from the side arm 13. A protruding block 134 is disposed below the pivoting portion 133, and the protruding block 134 is strip-shaped. The terminals 11 are disposed in two rows, and are correspondingly received in the receiving slots 121.
The cover 2 is pivotally disposed on the insulating body 10, and includes a body portion 21, two side portions 22 located at two sides of the body portion 21, and a recess 23 located between the side portion 22 and the body portion 21. The recess 23 is disposed at a rear end of the side portion 22. Each of the side portions 22 is disposed with two locking portions 221 corresponding to the fastening portions 131, and a sliding slot 222 corresponding to the pivoting portion 133. The locking portion 221 includes a notch 2210 formed from the cover 2 and a flat portion 2211 located within the notch 2210. During locking, the fastening portion 131 enters the notch 2210 and is fastened by the flat portion 2211 so as to lock the cover 2 to the base 1. The pivoting portion 133 is engaged with the sliding slot 222, and the sliding slot 222 is capable of displacing relative to the pivoting portion 133 in a front-to-rear direction, so as to drive the cover 2 to slide relative to the base 1 in the front-to-rear direction, thereby achieving locking and opening of the cover 2 to and from the base 1. The sliding slot 222 is an elongated slot, and has a front end 2221 and a rear end 2222. When the cover 2 slides backward so that the pivoting portion 133 is located at the front end 2221, the locking portion 221 locks the fastening portion 131, and the cover 2 is locked. When the cover 2 slides forward so that the pivoting portion 133 is located at the rear end 2222, the locking portion 221 unlocks the fastening portion 131, that is, the locking portion 221 is located within the reserved slot 132. At this time, an edge of the cover 2 presses against the protruding block 134, to prevent the sliding slot 222 from sliding relative to the pivoting portion 133, so that the cover 2 can be rotated stably about the pivoting portion 133 to be opened. As such, locking and opening of the cover 2 can be achieved.
Two elastic members 24 are disposed on the cover 2, and press against the insulating body 10. The elastic members 24 are disposed symmetrically about a longitudinal central line of the cover 2, and are adjacent to the pivoting portions 133 respectively, so that the elastic members 24 applies an even pressing force on the insulating body 10. In this embodiment, the elastic member 24 is an elastic piece integrally formed from the cover 2. In another embodiment, the elastic member 24 is formed by slitting the cover 2. In other embodiments, the elastic member 24 may be assembled to the cover 2, or may be configured in other shapes, in which the shapes that can be easily manufactured are preferred. The elastic member 24 is disposed within the recess 23, and extends backward from an edge of the recess 23. When the operator opens the cover 2, a certain distance is maintained between the elastic member 24 and a surface of the insulating body 10, so that the cover 2 can be easily opened by the operator without being pressed by the elastic member 24. The elastic member 24 includes a connecting portion 241 connected to the cover 2 and a bent portion 242 bent and extending from the connecting portion 241 toward the insulating body 10, and the bent portion 242 is capable of pressing against the surface of the insulating body 10, so as to provide good elasticity.
