Description

Technical Field

[0001] The present invention relates to a card holder and an electronic card connector, and particularly to a card holder and an electronic card connector with an automatic card ejection function. Background Art

[0002] Smartphones have become one of the essential electronic devices in people's lives. Usually, smartphones use a card holder to carry an electronic card and insert it into the smartphone to achieve communication functions. For example, a SIM card, also known as a Nano SIM card. To facilitate card replacement, the card holder usually has a card ejection mechanism. The card ejection mechanism includes a push rod and a crank. The push rod and the crank are linked and cooperate. When ejecting the card, first, manually or use a thimble to press the push rod to move backward. Then, the push rod drives the crank to rotate. Then, the crank presses against the card holder and gradually withdraws from the card seat, thereby achieving the card ejection function. Since the cooperation of the card holder, the push rod, and the crank is required, there are many parts and the assembly is complex. Moreover, the card seat needs to accommodate parts such as the push rod and the crank, making the size of the card seat larger.

[0003] Therefore, it is necessary to design a new card holder to solve the above technical problems. Summary of the Invention

[0005] To achieve the foregoing objectives, the present invention adopts the following technical solutions: A cato, which includes a body component, a door panel component, and an automatic telescopic locking mechanism. The body component is provided with a placement groove. The door panel component is movably installed at the front end of the body component in the front and rear directions. The automatic telescopic locking mechanism includes a pressure rod, a locking member, a guide rail member, and a spring. The front end of the pressure rod abuts against the door panel component, and the rear end abuts against the locking member. The guide rail member is fixed to the body component and sleeved outside the pressure rod. The spring abuts between the locking member and the body component. A plurality of triangular grooves are arranged on the rear end face of the pressure rod along the circumferential direction of the pressure rod. A plurality of locking ridges are arranged on the outer side surface of the locking member at intervals along the circumferential direction of the locking member. The guide rail member includes an annular wall. The annular wall is provided with a plurality of first locking grooves and a plurality of second locking grooves arranged along the circumferential direction of the guide rail member. The first locking grooves are triangular. The annular wall is further provided with a plurality of second locking grooves arranged at intervals along the circumferential direction of the guide rail member. Each of the second locking grooves penetrates through the annular wall and is located between two adjacent first locking grooves one by one. The second locking groove extends forward beyond the first locking groove. When the automatic telescopic locking mechanism is in a contracted state, the locking ridges abut forward against the triangular grooves and the first locking grooves, and the length by which the pressure rod protrudes forward from the guide rail member is a first length. When the automatic telescopic locking mechanism is in an extended state, the locking ridges disengage from the first locking grooves and enter the second locking grooves forward, and the length by which the pressure rod protrudes forward from the guide rail member is a second length, and the first length is less than the second length.

[0006] Further improvement: A circular hole penetrating through the front and rear is provided inside the pressure rod, and a convex column positioned in the circular hole is provided at the front end of the locking member.

[0007] Further improvement: Guide blocks are arranged on the outer side surface of the pressure rod at intervals along the circumferential direction of the pressure rod. The guide rail member is provided with a through hole penetrating through the front and rear and an annular wall surrounding the through hole. The pressure rod passes through the through hole. A plurality of guide grooves are provided on the inner wall of the through hole. The guide blocks are in one-to-one cooperation with the guide grooves for guiding the forward and backward movement of the pressure rod.

[0008] Further improvement: The number of the automatic telescopic locking mechanisms is a pair, spaced apart left and right.

[0009] Further improvement: The door panel component includes a movable plate extending backward into the body component. The movable plate is provided with a guide hole extending in the front and rear directions. The body component is provided with a rotating shaft passing through the guide hole for restricting the displacement of the door panel component in the front and rear directions.

[0010] Further improvement: The body component is provided with a locking elastic sheet, and the movable plate is provided with locking convex points for engaging with the locking elastic sheet.

[0011] For further improvement, the door panel assembly is provided with a hook spring piece for hooking on the notch of the housing.

[0012] For further improvement, the body assembly includes an insulator and a metal housing. The insulator is injection molded on the metal housing. The metal housing is provided with an activity space and a receiving space. The activity space and the receiving space are separated left and right. The movable plate extends into the activity space. The automatic telescopic locking mechanism is received in the receiving space. The rotating shaft is fixed to the metal housing.

[0013] For further improvement, the metal housing includes a first housing and a second housing fixed together up and down. The first housing includes an upper wall and first side walls bent downward from both left and right ends of the upper wall. The second housing includes a lower wall opposite to the upper wall up and down and second side walls bent upward from both left and right ends of the lower wall. The activity space is between the upper wall, the lower wall and the two second side walls. The receiving space is between the upper wall, the first side wall and the second side wall. The rotating shaft is fixed to the upper wall and the lower wall.

[0014] The present invention also adopts the following technical solution: an electronic card connector, which includes a card seat and the above-mentioned card holder. The card holder is inserted into the card seat.

[0015] After the door panel assembly of the card holder of the present invention is pressed, the door panel assembly presses against the automatic telescopic locking mechanism to switch between the retracted state and the extended state. When the automatic telescopic locking mechanism is in the retracted state, the door panel assembly of the card holder is received in the housing. When the automatic telescopic locking mechanism is in the extended state, the door panel assembly exposes the housing. Pulling the door panel by hand can easily pull out the card holder from the card seat, which is more convenient to use. The components of the card seat (push rod, crank) are simplified, making the assembly of the card seat simple. At the same time, when the user ejects the card, he can directly operate manually without an external auxiliary tool (ejector pin), which greatly facilitates the use of the customer. The card holder is arranged in this way, correspondingly simplifying the components of the electronic card connector, with a simple assembly and convenient card ejection operation.
