SUMMERY OF THE UTILITY MODEL

The embodiment of the utility model provides a technical problem that will solve provides a mould frame convenient to PCB board impedance test, aims at solving among the prior art and places the PCB board and place unstable, the low and poor problem of test stability of placing that the impedance test exists on the test table.

The embodiment of the utility model provides a realize like this, provide a mould frame convenient to PCB board hinders anti test, this mould frame includes the base and is used for supporting the support of PCB board, the spliced eye that a plurality of mutual intervals set up is seted up to the upper end of base, the axis perpendicular to of spliced eye the upper surface of base, the support includes inserted bar and bracing piece, the lower extreme detachably of inserted bar inserts and arranges in the spliced eye, the upper end of inserted bar with the lower extreme of bracing piece is connected, and the upper end of inserted bar with form a step that is used for supporting the PCB board between the lower extreme of bracing piece.

Furthermore, the plug hole is a blind hole.

Furthermore, the cross sections of the insertion rod and the support rod are cylindrical, and the cross section area of the insertion rod is larger than that of the support rod.

Further, the axis of the insertion rod coincides with the axis of the support rod.

Further, the base is cuboid.

Furthermore, the plurality of inserting holes are uniformly distributed on the upper surface of the base.

Compared with the prior art, the embodiment of the utility model, beneficial effect lies in: the utility model discloses according to PCB board design size and the locating hole position on it, peg graft in the corresponding jack at the base with peg graft pole detachably on the support, peg graft in the locating hole on the PCB board through the bracing piece on the support, the PCB board is supported with the step that the bracing piece lower extreme formed to the utilization peg graft pole upper end, thereby can be fixed with the PCB board is unsettled steadily, and then can hinder when testing at the PCB board, two test points of impedance instrument probe can be atress completely on the point position on the PCB board, need not to debug many times, once only can obtain the test result, it has the advantage that efficiency of software testing is high and test stability is good.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to fig. 3, the present invention provides a mold rack for testing the impedance of a PCB. This mould frame includes base 1 and the support 2 that is used for supporting PCB board 100, and wherein, a plurality of spliced eye 10 that set up at intervals each other are seted up to base 1's upper end, and specifically, base 1 is the cuboid, and a plurality of spliced eye 10 evenly distributes in base 1's upper surface, and this spliced eye 10 is the blind hole to its cross section is circular.

The support 2 comprises an inserting rod 21 and a supporting rod 22 which are connected into a whole, and the cross sections of the inserting rod 21 and the supporting rod 22 are cylindrical. The lower end of the insertion rod 21 is detachably inserted into the insertion hole 10 of the base 1, and the axis of the insertion hole 10 is perpendicular to the upper surface of the base 1, so that the insertion rod 21 can be vertically inserted into the upper end of the base 1. The upper end of the inserting rod 21 is connected with the lower end of the supporting rod 22, and a step 20 for supporting the PCB 100 is formed between the upper end of the inserting rod 21 and the lower end of the supporting rod 22.

In the above embodiment, the cross-sectional area of the inserting rod 21 is larger than that of the supporting rod 22, and the axes of the inserting rod 21 and the supporting rod 22 are overlapped with each other, so that the supporting rod 22 is located at the middle position of the upper end of the inserting rod 21, and the step 20 formed between the upper end of the inserting rod 21 and the lower end of the supporting rod 22 can stably support the PCB 100.

To sum up, the utility model discloses a mould frame convenient to 100 impedance test of PCB board is according to the PCB board 100 design size and the locating hole position on it, peg graft peg 21 detachably on the support 2 in corresponding spliced eye 10 at base 1, make can correspond to insert in the locating hole on PCB board 100 through bracing piece 22 on the support 2, and utilize the step 20 that peg 21 upper end and bracing piece 22 lower extreme formed to support PCB board 100, thereby can be stably with PCB board 100 unsettled fixed, and then when carrying out impedance test to PCB board 100, two test points of impedance instrument probe can be atred completely on the position on PCB board 100, need not to debug many times, once only can obtain the test result, it has the advantage that efficiency of software testing is high and test stability is good.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
