Description

Screw and interface card

The invention relates to a screw and an interface card, in particular to a screw and an interface card attached to a hand-turned lock.

The structure of a general screw is roughly divided into a rod and a head, and the periphery of the rod is threaded to increase the fastness of the combination with the object when it is locked. The head has a larger cross-section, which is intended for tool insertion and force application. The head is provided with slots for inserting tools. For example, in addition to the conventionally known one-shaped or cross-shaped, there are also hexagonal, quincunx and so on. When it is locked, a screwdriver or wrench with a corresponding cross-sectional shape and size is inserted into the slot or socket part to facilitate rotation and force.

However, the above-mentioned traditional screw lock cooperation industry needs to be carried out with tools. If there is no corresponding tool, the combination of objects cannot be carried out, which is extremely inconvenient. In view of this, the related industry has proposed a hand-turned screw that allows the user to directly lock the screw with both hands.

In order to allow the user to turn the screw with both hands, a circle of electronic component keepout area (keepout area) needs to be designed around the screw hole of the corresponding hand screw on the circuit board to free up the operating area for the finger to hold the screw head, and then Make it easier for users to apply force. However, with the design trend of light, thin, short and small electronic products, the space on the circuit board is becoming more and more urgent, and the forbidden area required by the conventional hand-turned screw reduces the space for placing electronic parts on the circuit board.

The present invention is to provide a screw and an interface card, so as to balance the convenience of turning the screw with the effective utilization of the layout space of the circuit board.

The screw disclosed in an embodiment of the present invention includes a screw member and an operating member. The screw member includes a head and a body. The body is connected to the head, and the diameter of the body is smaller than the diameter of the head. The side of the head away from the body includes an operating groove. The operating member is pivoted on the head to rotate between an operating position and a storage position. Wherein, when the operating element is located in the operating position, a part of the operating element is located on the side of the head away from the body, and when the operating element is located in the storage position, the operating element is separated from the head and away from the body One side.

The interface card disclosed in another embodiment of the present invention is suitable for being installed on a motherboard. The interface card includes a circuit board and a screw. The screw includes an assembly part, a screw part and an operating part. The assembly is installed on the circuit board. The screw member includes a head and a body. The body is connected to the head. The side of the head away from the body includes an operating groove. The screw fitting penetrates through the assembly, and at least part of the body is surrounded by the assembly. The operating member is pivoted on the head to rotate between an operating position and a storage position. Wherein, when the operating element is located in the operating position, a part of the operating element is located on the side of the head away from the body, and when the operating element is located in the storage position, the operating element is separated from the head and away from the body One side.

According to the screw and the interface card of the above-mentioned embodiment, since the screw has an operating member and the head of the screw member is provided with an operating groove, the screw can be used in both tool-free and tool-free operation modes.

Furthermore, because the operating member is pivoted on the screw member, when the assembler wants to turn the screw member directly with his fingers without tools, he can pull the operating member until the head of the screw member is far away from the body. One side. In this way, the fingers of the assembler will not be interfered by the electronic parts around the screw. That is to say, when designing the layout of the electronic parts of the interface card, it is not necessary to reserve the space required by the assembler to turn the screws, and a circle of electronic parts forbidden area (keepout area) is deliberately designed around the screws. In this way, the layout space of the electronic components of the interface card can be effectively increased, so that the interface card can be equipped with more electronic components to improve the performance of the interface card, or the size of the interface card can be reduced to meet the light, thin and short design of electronic products. trend.

The screw 10 includes an assembly part 100, a screw part 200, an operating part 300, a pivot 400 and an elastic part 500.

The assembly 100 includes a cylindrical portion 110 and an abutting convex portion 120. The barrel 110 is assembled to the circuit board 20 by welding, for example. The abutting convex portion 120 protrudes from the outer annular surface 111 of the cylindrical portion 110.

The screw member 200 includes a head 210 and a body 220. The body 220 is connected to the head 210, and the diameter of the body 220 is smaller than the diameter of the head 210. A side of the head 210 away from the body 220 includes an operating slot 211. The outer shape of the operation slot 211 is, for example, a cross shape, a straight shape, a hexagonal shape, or a quincunx shape.

The body 220 of the screw member 200 passes through the assembly 100, and at least part of the body 220 is surrounded by the assembly 100. In detail, the body 220 of the screw 200 includes a connecting section 221, a stopping section 222 and a threaded section 223 connected to each other. The connecting section 221 is connected to a side of the head 210 away from the operating slot 211. The diameters of the connecting section 221 and the threaded section 223 are the same as D3, and the diameter D3 of the connecting section 221 is matched with the diameter of the barrel 110 for the connecting section 221 to pass through. The diameter D2 of the stop section 222 is greater than the diameter D3 of the connecting section 221. The diameter of the body 220 is represented by the maximum diameter of the body 220, that is, the diameter of the body 220 is the diameter D2 of the stop section 222, and the diameter D2 of the stop section 222 of the body 220 is smaller than the diameter D2 of the stop section 222. The diameter of the head 210 is D1. The connecting section 221 penetrates the barrel 110, and the stop section 222 and the threaded section 223 are surrounded by the barrel 110. Because the stop 222 The diameter D2 of the head 210 and the diameter D1 of the head 210 are both larger than the diameter D3 of the connecting section 221, so the stop section 222 and the head 210 interfere with the barrel 110 to prevent the screw 200 from being separated from the assembly 100.

In this embodiment, the connecting section 221 and the threaded section 223 have the same diameter, but it is not limited thereto. In other embodiments, the diameter of the connecting section and the threaded section may also be different.

The operating member 300 includes a hand-held portion 310 and two pivotal portions 320. The two pivoting parts 320 protrude from one side of the holding part 310, and the holding part 310 and the two pivoting parts 320 jointly surround a relief space S. The two pivotal parts 320 are pivotally connected to the head 210 of the screw member 200 through the pivot 400, and the head 210 of the screw member 200 is located between the two pivotal parts 320. Make way for space S. The operating member 300 can pivot between an operating position (as shown in FIG. 4) and a storage position (as shown in FIG. 5) through the pivot 400 relative to the screw member 200. When the operating element 300 is located at the operating position, a part of the operating element 300 is located on the side of the head 210 away from the body 220. When the operating element 300 is located at the storage position, the operating element 300 is separated from the head 210 is away from one side of the body 220.

The elastic member 500 is, for example, a compression spring, and is sandwiched between the abutting protrusion 120 of the assembly 100 and the head 210 of the screw member 200 so that the head 210 of the screw member 200 faces The direction relatively away from the barrel 110 is offset.

In this embodiment, the elastic member 500 is a compression spring as an example, but it is not limited to this. In other embodiments, the elastic member may also be a tension spring.

There are two ways to use the screw 10, please refer to Figure 4 to Figure 5. 4 and 5 are schematic diagrams of assembling the interface card of FIG. 1.

As shown in Figure 4, when the assembler does not have a screwdriver or other hand tools at hand, the group The installer can pull up the operating member 300 of the screw 10 to the operating position along the direction a. In this way, the user can directly use the finger to turn the operating member 300, and drive the threaded section 223 of the screw member 200 to lock to the motherboard 2 through the operating member 300, or drive the threaded section of the screw member 200 through the operating member 300 223 is separated from the motherboard 2.

When the operating member 300 is pulled up to the operating position, the assembler's fingers are located at a position where the head 210 of the screw member 200 is away from the body 220, so the assembler's fingers will not be interfered by the electronic components around the screw 10. That is to say, when designing the layout of the electronic parts of the interface card, it is not necessary to reserve the space required by the assembler to turn the screws, and a circle of electronic parts forbidden area (keepout area) is deliberately designed around the screws. In this way, the layout space of the electronic components of the interface card can be effectively increased, so that the interface card can be equipped with more electronic components to improve the performance of the interface card, or the size of the interface card can be reduced to meet the light, thin and short design of electronic products. trend.

As shown in Figure 5, when the assembler feels that it is necessary for the screw 10 to have a greater locking force, that is to say, to allow the screw 10 to be more securely attached to the motherboard 2, the assembler can also follow the direction b Pull down the operating member 300 of the screw 10 to the storage position. In this way, the operating slot 211 of the head 210 is no longer blocked by the operating member 300, so that the assembler can use a hand tool 3 such as a screwdriver to tighten or loosen the screw member 200.

According to the screw and the interface card of the above-mentioned embodiment, since the screw has an operating member and the head of the screw member is provided with an operating groove, the screw can be used in both tool-free and tool-free operation modes.

Furthermore, because the operating member is pivoted on the screw member, when the assembler wants to turn the screw member directly with his fingers without tools, he can pull the operating member until the head of the screw member is far away from the body. One side. In this way, the fingers of the assembler will not be interfered by the electronic parts around the screw. That is to say, when designing the layout of the electronic parts of the interface card, it is not necessary to reserve the space required by the assembler to turn the screws, and a circle of electronic parts forbidden area (keepout area) is deliberately designed around the screws. In this way, the layout space of the electronic components of the interface card can be effectively increased, so that the interface card can be equipped with more electronic components to improve the performance of the interface card, or the size of the interface card can be reduced to meet the light, thin and short design of electronic products. trend.
