Description

Technical Field

[0001] This utility model relates to the field of card connectors, and in particular to a CF card female connector. Background Technology

[0002] CF cards were originally designed as data storage devices for portable electronic devices. Revolutionizing storage with the use of flash memory, they were first manufactured and standardized by SanDisk in 1994, and their physical format is now used in a wide variety of devices. Because the NOR flash memory they used had a lower storage density than the newer NAND flash memory, CF cards were the largest of the three types of memory cards that appeared in the early 1990s, the other two being Miniature Cards—MiniCard and SmartMedia cards. CF was one of the first flash memory standards to compete with the earlier and larger PCMCIA Type I memory cards. Initially built on Intel's NOR flash memory, it was later switched to NAND flash memory, making CF one of the oldest and most successful standards, particularly suitable for the professional camera market. It offers a longer lifespan and lower cost per unit capacity compared to other storage methods, while also providing a large capacity in a smaller size.

[0003] Currently, almost all point-and-shoot cameras, mirrorless cameras, and professional SLR digital cameras use CF cards as their storage medium. Therefore, digital cameras generally have CF card slots for inserting and connecting CF cards. Currently, there is a type of CF card female connector on the market with flared terminal openings. When the male connector is inserted into this female connector, the male's pins make contact with the female's terminals. If the female connector's terminal opening is too large, the male's pins may not make good contact. To ensure reliable contact and conduction between the male and female terminals, the female connector's terminal opening is usually slightly smaller. After insertion, the male's pins open the female connector's terminal opening, thus ensuring reliable contact and conduction. However, this method easily damages the female connector's terminals, shortening its lifespan. Therefore, it is necessary to improve the existing CF card female connector. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a CF card female connector that can effectively solve the problem that the terminals of the female connector are easily damaged and the service life of the CF card female connector is shortened after the male connector is plugged in.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A CF card socket includes an insulating body and multiple terminals. The insulating body has multiple terminal slots, each with a guide protrusion at its front end. The inner distance between the guide protrusions decreases sequentially from front to back. Each terminal is placed into its corresponding terminal slot. Each terminal includes an integrally formed upper contact portion, lower contact portion, main body portion, and solder portion. The upper and lower contact portions extend forward from the front end of the main body portion and together form a contact cavity. The opening of the contact cavity is funnel-shaped. The inner surfaces of the upper and lower contact portions respectively contact the sides of the guide protrusions. The main body portion is located within the terminal slots, and the solder portion extends rearward from the rear end of the main body portion and protrudes outward from the terminal slots.

[0007] As a preferred embodiment, the cross-sections of both the upper and lower contact portions are crescent-shaped.

[0008] As a preferred embodiment, a boss is provided on one side of the rear end of the plurality of terminal slots. The boss, together with the top and bottom surfaces of the terminal slots, forms a limiting groove. The main body includes a first main section, a second main section, and a third main section. The first and second main sections extend integrally to the left or right from the upper and lower sides of the third main section, respectively, so that the cross-section of the main body is U-shaped. The first and second main sections are respectively located in the corresponding limiting grooves for limiting. This design can prevent the terminals from being installed backwards, and the limiting grooves can limit and protect the main body, preventing deformation caused by external forces during assembly.

[0009] As a preferred embodiment, locking points are provided on one side of the first main body segment and one side of the second main body segment. The locking points of the first main body segment and the second main body segment are directly opposite each other. This design can prevent the welding part of the terminal from being misaligned due to the different positions of the locking points when the terminal is inserted.

[0010] As a preferred embodiment, locking points are provided on one side of the rear end of the first main body segment and one side of the rear end of the second main body segment. The locking points of the first main body segment and the second main body segment are directly opposite each other. The locking points are located on the rear side of the main body, so that a buffer surface is formed in front of the locking points, which effectively extends the buffer distance and can prevent problems such as insufficient coplanarity and poor linearity of the welding part of the terminal when the terminal is pressed into the insulating body due to insufficient buffer distance.

[0011] As a preferred embodiment, both the rear ends of the upper contact portion and the lower contact portion extend rearward with extension portions. The rear ends of these extension portions are integrally formed and connected to the main body. This design can extend the length of the contact cavity, making card insertion smoother and requiring less force. It also reduces the wear and tear on the female connector during card insertion, thus extending its service life.

[0012] As a preferred embodiment, a baffle is provided at the rear end of the insulating body.

[0013] As a preferred embodiment, the rear end of the main body is connected to a material strip with a clearance groove. This design prevents interference between the terminal and the baffle of the insulating body when the terminal is inserted. Previously, the terminal needed to be pressed in twice to be pressed into place, but with this design, it only needs to be pressed in once, reducing the terminal assembly process and improving production efficiency.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] By providing a guide protrusion at the front end of the terminal slot, the inner distance of the guide protrusion decreases from front to back. During the assembly process, the terminal is inserted from the rear end of the terminal slot. When the upper and lower contact parts contact the guide protrusion and are inserted forward, the guide protrusion gradually opens the upper and lower contact parts. This ensures that the opening of the contact cavity is just right after the terminal is assembled. During the insertion of the male PIN into the contact cavity, the terminal will not be subjected to impact force and is not easily damaged, effectively extending the service life of the CF card socket.

[0036] Please refer to Figures 1 to 8 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10 and a plurality of terminals 20.

[0037] The insulating body 10 has multiple terminal slots 11, and the front end of the multiple terminal slots 11 is provided with a guide protrusion 12. The inner distance of the guide protrusion 12 decreases from front to back. In this embodiment, a boss 13 is provided on one side of the rear end of the multiple terminal slots 11. The boss 13, the top surface and the bottom surface of the terminal slots 11 together form a limiting groove 14. A baffle 15 is provided at the rear end of the insulating body 10.

[0038] The plurality of terminals 20 are respectively placed into corresponding terminal slots 11. Each of the plurality of terminals 20 includes an integrally formed upper contact portion 21, a lower contact portion 22, a main body portion 23, and a welding portion 24. The upper contact portion 21 and the lower contact portion 22 both extend forward from the front end of the main body portion 23, and the upper contact portion 21 and the lower contact portion 22 together form a contact cavity 201. The opening of the contact cavity 201 is funnel-shaped. The inner side surface of the upper contact portion 21 and the inner side surface of the lower contact portion 22 respectively contact the two sides of the guide protrusion 12. The main body portion 23 is located in the terminal slot 11, and the welding portion 24 extends rearward from the rear end of the main body portion 23 and extends outward from the terminal slot 11. In this embodiment, the cross-section of the upper contact portion 21 and the lower contact portion 22 are... The cross-section of part 22 is crescent-shaped. The main body part 23 includes a first main body segment 231, a second main body segment 232, and a third main body segment 233. The first main body segment 231 and the second main body segment 232 extend integrally to the left or right from the upper and lower sides of the third main body segment 233, respectively, making the cross-section of the main body part 23 U-shaped. The first main body segment 231 and the second main body segment 232 are respectively located in corresponding limiting grooves 14 for limiting. This design can prevent the terminal 20 from being installed backwards, and the limiting grooves 14 can limit and protect the main body part 23, preventing deformation caused by external forces during assembly. A locking point 202 is provided on one side of the first main body segment 231 and one side of the second main body segment 232. The locking point of the first main body segment 231 is... The locking points 202 of the first main body segment 231 and the second main body segment 232 are vertically aligned. This design prevents the welding part 24 of the terminal 20 from being misaligned due to the different positions of the locking points 202 when the terminal 20 is inserted. Specifically, locking points 202 are provided on one side of the rear end of the first main body segment 231 and the rear end of the second main body segment 232. The locking points 202 of the first main body segment 231 and the second main body segment 232 are vertically aligned. The locking points 202 are located on the rear side of the main body segment 23, so that a buffer surface 203 is formed in front of the locking points 202, which effectively extends the buffer distance and prevents problems such as insufficient coplanarity and poor linearity of the welding part 24 of the terminal 20 when the terminal 20 is pressed into the insulating body 10 due to insufficient buffer distance. Furthermore, both the rear ends of the upper contact portion 21 and the lower contact portion 22 extend rearward to form extension portions 25. The rear ends of the extension portions 25 are integrally formed and connected to the main body portion 23. This design can extend the length of the contact cavity 201, making card insertion smoother and requiring less force. It also reduces the wear on the female connector during card insertion, thus extending its service life. Additionally, the rear end of the main body portion 23 is connected to a material strip 30, which has a clearance groove 31. This design can prevent the terminal 20 from interfering with the baffle 15 of the insulating body 10 when it is inserted. Previously, the terminal 20 required two pressings to be pressed into place, but with this design, it only needs to be pressed into place once, reducing the assembly process of the terminal 20 and improving production efficiency.

[0039] The key design feature of this invention is that a guide protrusion is provided at the front end of the terminal slot, with the inner distance of the guide protrusion decreasing sequentially from front to back. During the assembly process, the terminal is inserted from the rear end of the terminal slot. When the upper and lower contact parts contact the guide protrusion and are inserted forward, the guide protrusion gradually opens the upper and lower contact parts, ensuring that the opening of the contact cavity is just right after the terminal is assembled. During the insertion of the male pin into the contact cavity, the terminal will not be subjected to impact force and is not easily damaged, effectively extending the service life of the CF card socket.

[0040] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
