Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and more particularly to a circuit board with long and short gold fingers. Background Art

[0002] A circuit board is an important electronic component, a support for electronic components, and a carrier for the electrical connection of electronic components. Therefore, it is relatively important. For example, on a computer memory module and a graphics card, we can see a row of golden conductive contacts, which are called "gold fingers".

[0003] A gold finger board is a circuit board formed by welding gold fingers on a substrate. However, once the length of the existing gold finger board is fixed, it cannot be adjusted, resulting in poor practicability. Therefore, it needs to be improved. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a circuit board with long and short gold fingers, which solves the problem that the length of the gold finger board on the market at present cannot be adjusted according to needs, resulting in poor practical effects.

[0005] To solve the above technical problems, the technical solution of the utility model is: a circuit board with long and short gold fingers, including a circuit board, on which a gold finger connecting wire is welded. One end of the gold finger connecting wire is connected to the circuit on the circuit board. It is characterized in that it further includes more than one group of gold finger components. Each group of gold finger components includes more than one gold finger with different lengths. The other end of the gold finger connecting wire is provided with a mounting hole, which is arranged on the circuit board. And a connecting component is detachably connected to the mounting hole. The connecting component includes an insulating head and an insulating base connected by threads. Below the insulating head, there is an insulating rod inserted into the mounting hole. A conductive sleeve is sleeved outside the insulating rod. A through hole is arranged on each gold finger. The conductive sleeve is inserted into the through hole. The lower part of the insulating rod is threadedly connected to the insulating base.

[0006] Preferably, in order to improve the insulation of the insulating head, an insulating silica gel sleeve is further sleeved outside the insulating rod. The insulating silica gel sleeve presses the gold finger towards the gold finger connecting wire.

[0007] Preferably, to further ensure the electrical connection between the gold finger and the gold finger connecting wire, welding pads are arranged around the upper part of the mounting hole and are welded to the gold finger connecting wire.

[0008] Preferably, the welding pad is of an annular structure.

[0009] Preferably, the gold finger component includes more than three gold fingers with different lengths.

[0010] Preferably, an insulating lining is provided on the inner side of the conductive sleeve.

[0011] Preferably, one or more silicone strips are provided at intervals within the insulating lining.

[0012] Preferably, an extension ring that mates with the bottom of the circuit board is provided at the bottom of the conductive sleeve.

[0013] Preferably, one or more insulating stop strips are provided at intervals on the circuit board.

[0014] Preferably, in order to always ensure the electrical connection between the gold fingers and the gold finger connecting wires, a spring is sleeved outside the insulating rod, with one end abutting against the lower end face of the insulating head and the other end abutting against the upper end face of the gold finger.

[0015] Compared with the prior art, the beneficial technical effect of the present utility model is that this structure realizes detachable connection between the gold fingers and the gold finger connecting wires, enabling selection of gold fingers of appropriate lengths according to requirements. During installation, select gold fingers of appropriate sizes according to the length requirements, then separate the insulating head from the insulating base. First, insert the insulating rod into the through holes of the gold fingers and also into the installation holes, and then threadedly connect the lower part of the insulating rod to the insulating base to achieve fixation. Therefore, this structure enables adjustment of the gold finger length as needed to adapt to different installation requirements. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the gold finger connection wire 2 is connected to the circuit on the circuit board 1. It is characterized in that it further includes more than one group of gold finger components 4. Each group of gold finger components 4 includes more than one gold finger 4-1 with different lengths. The other end of the gold finger connection wire 2 is provided with a mounting hole 5, which is arranged on the circuit board 1, and a connection component 6 is detachably connected to the mounting hole 5. The connection component 6 includes an insulating head 6-1 and an insulating base 6-2 connected by threads.

A through hole 7 is arranged on each gold finger 4-1, and the electrically conductive sleeve 6-4 is inserted into the through hole 7. The lower part of the insulating rod 6-3 is threadedly connected to the insulating base 6-2. Preferably, the gold finger component 4 includes more than three gold fingers 4-1 with different lengths.

[0033] This structure realizes the detachable connection between the gold finger 4-1 and the gold finger connection wire 2, enabling the selection of a gold finger 4-1 with a suitable length according to requirements. During installation, select a gold finger 4-1 with a suitable size according to the length requirement, then separate the insulating head 6-1 from the insulating base 6-2. First, insert the insulating rod 6-3 into the through hole 7 of the gold finger 4-1 and insert the insulating rod 6-3 into the mounting hole 5, and then threadedly connect the lower part of the insulating rod 6-3 to the insulating base 6-2 to achieve fixation.

The insulating silica gel sleeve 8 presses the gold finger 4-1 towards the gold finger connecting wire 2. By sleeving an insulating silica gel sleeve 8 outside the insulating rod 6-3, it is always ensured that the gold finger 4-1 is pressed towards the gold finger connecting wire 2, further improving the connectivity between the gold finger 4-1 and the gold finger connecting wire 2. Through the above structural settings, the insulation property is improved, and only the connectivity between the gold finger connecting wire 2 and the gold finger 4-1 is ensured.

[0036] Embodiment 3:

[0037] As Figure 6 shown in the figure, the general structure of a long and short gold finger circuit board disclosed in this embodiment is the same as that of Embodiment 1. The difference is that, preferably, to further ensure the electrical connection between the gold finger 4-1 and the gold finger connecting wire 2, solder pads 9 for welding with the gold finger connecting wire 2 are provided around the upper part of the mounting hole 5.

[0041] Preferably, one or more silica gel strips 11 are arranged at intervals inside the insulating inner lining 10.

[0042] Preferably, an extension ring 12 for cooperating with the bottom of the circuit board 1 is provided at the bottom of the conductive sleeve 6-4. Through the above structure, the insulation property is improved by providing the insulating inner lining 10 inside the conductive sleeve 6-4, and at the same time, the friction force is increased by providing the silica gel strips 11 inside the insulating inner lining 10.

The difference is that, preferably, one or more insulating blocking strips 13 are arranged at intervals on the circuit board 1. Through the above structural settings, the pattern effect between two adjacent gold fingers 4-1 is further improved by increasing the blocking strips 13.

[0045] Embodiment 6:

[0046] AsFigure 10 As shown, the general structure of a long and short gold finger circuit board disclosed in this embodiment is the same as that of Embodiment 1. The difference is that, preferably, in order to always ensure the electrical connection between the gold finger 4-1 and the gold finger connection line 2, a spring 3 is sleeved outside the insulating rod 6-3, with one end abutting against the lower end surface of the insulating head 6-1 and the other end abutting against the upper end surface of the gold finger 4-1.
