Description

Technical Field

[0001] The utility model belongs to the field of auxiliary tools for flexible circuit board line detection and relates to a micro probe seat. Background Art

[0002] Flexible Printed Circuit (FPC), also known as soft circuit board or flexible circuit board, is popular for its excellent properties such as light weight, thin thickness, and free bending and folding.

[0003] The width of the metal contacts at both ends of the flexible circuit board is about 1mm, and the spacing is about 1mm. When measuring its performance, two sets of probes (two probes in each set) are required to touch the metal contacts at both ends respectively and stay for 1 to 2 seconds, waiting for the oscilloscope to analyze whether the electrical signal is qualified.

[0004] Depending on the measurement requirements, sometimes the probes need to be inserted into two adjacent contacts (as shown in Figure 1 (a)), and sometimes they need to be inserted into the contacts that are one position apart (as shown in Figure 1 (b)). In the past, this process required at least two workers to operate simultaneously (two people each holding a set of probes to insert into the contacts at both ends of the circuit board), which was costly.

It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other. Example

[0027] See also Figure 2-Figure 4 As shown, a micro probe seat includes a base 1, a first support 3 for placing a first probe 2 and a second support 5 for placing a second probe 4 are arranged on the outer side of the base 1, and an adjustment component is arranged on the base 1, the above-mentioned adjustment component is connected to the first support 3 through a first transmission shaft 6, and the above-mentioned adjustment component is connected to the second support 5 through a second transmission shaft 7, so that the above-mentioned first support 3 and the second support 5 rotate synchronously in opposite directions under the drive of the adjustment component.

[0028] Specifically, a gear cavity 101 is provided in the base 1, and the above-mentioned adjustment component includes an adjusting rod 8, one end of the adjusting rod 8 is exposed outside the base 1, and the other end extends into the gear cavity 101 and is fixedly connected with the bevel gear 9, and a first gear 10 and a second gear 11 are provided in the gear cavity 101, which are meshed and transmitted with the bevel gear 9 on the adjusting rod 8. The bevel gear 9 on the adjusting rod and the first gear 10 are transmitted in a forward direction, and the bevel gear 9 on the adjusting rod and the second gear 11 are transmitted in an inverted manner, so that the first gear 10 and the second gear 11 rotate in the opposite direction driven by the adjusting rod.

[0029] The base 1 has a transmission channel for the first transmission shaft 6 to pass through, a transverse channel is provided in the first transmission shaft 6, a second transmission shaft 7 is provided in the transverse channel, one end of the second transmission shaft 7 passes through the first support 3 and is connected to the second support 5, and the other end of the second transmission shaft 7 passes through the first gear 10 and is connected to the second gear 11. In order to prevent the first transmission shaft 6 and the second transmission shaft 7 from interfering with each other, a bearing is provided between the second transmission shaft 7 and the first gear 10 and the first support 3.

[0030] Since the first transmission shaft 6 will also rotate relative to the base 1 during use, in order to reduce the friction loss of the first transmission shaft 6 during rotation, the inner surface of the transmission channel can be made into a smooth curved surface, or a group of bearings can be arranged between the transmission channel and the first transmission shaft 6, and the above group of bearings are distributed at both ends of the transmission channel.

[0031] Through the above structural design, the operator can rotate the adjustment rod 8 to synchronously drive the first support 3 and the second support 5 to rotate in opposite directions, wherein the axis center lines of the first transmission shaft 6 and the second transmission shaft 7 coincide with each other, so that the first support 3 and the second support 5 are distributed in a "V" shape.

[0032] A vertical through hole is provided on the base 2, and an adjusting rod 8 is vertically provided in the vertical through hole. The upper end of the adjusting rod 8 is a knob, and the outline of the knob is larger than the diameter of the vertical through hole, so that the knob will not sink into the vertical through hole. A bevel gear 9 is provided at the lower end of the adjusting rod 8, and the bevel gear 9 is completely exposed in the gear cavity 101, and will not contact the vertical through hole during use.

[0033] Preferably, a protective cover 12 is provided on the periphery of the gear cavity 101 , and the protective cover 12 is detachably provided on the base 1 to shield the gear transmission structure and enhance the overall appearance.

[0034] In this embodiment, the first support 3 has a first carrier protruding outward, and the first carrier is provided with a first slot for placing the first probe 2. The first probe 2 is placed in the first slot and clamped, so that the first probe 2 is fixed on the first support 3. Similarly, the second support 5 has a second carrier protruding outward, and the second carrier is provided with a second slot for placing the second probe 4. The second probe 4 is placed in the second slot and clamped, so that the second probe 4 is fixed on the second support 5. When the first probe 2 and the second probe 4 are installed in place, the probe of the first probe and the probe of the second probe are distributed at the same height, and can then contact the metal contact on the flexible circuit board S synchronously.

[0035] The utility model uses a gear-driven adjustment component to make the first support and the second support rotate synchronously in opposite directions under the drive of the adjustment component. On-site personnel only need to rotate the adjustment rod to adjust the distance between the probe of the first probe and the probe of the second probe. Since the first probe and the second probe rotate synchronously, the probe height of the first probe and the probe height of the second probe are always consistent, so that the miniature probe seat can be applied to different types of measurement requirements, and a single person can complete tests of different specifications, saving labor costs.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
