Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Embodiment 1, refer to fig. 1-3, a general test fixture includes a substrate 1 and a bottom plate 5 that are arranged in parallel and are fixedly connected, a connection conduction band 3 is etched on the upper surface of the substrate 1, a pin pad is etched on the lower surface of the substrate 1, the connection conduction band 3 is connected with the pin pad through a via hole, a DIP locking seat 2 is installed on the substrate 1, a pin of the DIP locking seat 2 penetrates through the via hole and is welded and fixed with the pin pad, N test interfaces 4 are arranged and welded on the connection conduction band 3 in parallel, N is greater than or equal to 1, a measurement connector is convenient to connect according to a product pin definition, and only the measurement connector needs to be replaced with the test interface 4 corresponding to the pin of the test product after the test product is replaced.

In this embodiment, the test interface 4 is soldered in the area of the connection conduction band 3 of the substrate 1 by soldering, and the test interface 4 is a standard interface for connecting various instruments and meters. When this embodiment was implemented, during electronic components pin inserted DIP locking seat 2, because DIP locking seat 2 pins and pin pad welded fastening, the welding pad passes through via hole connection with being connected conduction band 3, consequently DIP locking seat 2 pins are connected with being connected conduction band 3 in essence, and the conduction band figure of being connected conduction band 3 can carry out design and processing according to the actual production condition. Because the test interface 4 is welded and fixed on the connecting conduction band 3, the DIP locking seat 2 is connected with the test interface 4. That is, the test interface 4 can be directly connected to the test equipment to detect the electronic component.

The clamps of this embodiment are used in pairs, can install on equipment, also can directly place on the desktop. Because electronic components are mainly dual in-line type, two rows of pins of the electronic components can be respectively inserted into the DIP locking seats 2 in the two groups of clamps, and the distance between the two clamps is controlled to place devices with different pin intervals. After the pins are connected, the test can be performed through the test interface 4.

Further, base plate 1 is two-sided copper-clad insulation board, for the conventional material among the prior art, low cost, and base plate 1 links firmly through epoxy glue bonding with bottom plate 5, makes the pin pad on the base plate 1 unsettled, guarantees to be insulating with equipment and test desktop, is convenient for fix.

Embodiment 3, because DIP locking seat 2 passes the pin pad welding of via hole and 1 bottom of base plate, for the welding of convenience, bottom plate 5 corresponds DIP locking seat 2's surface fretwork, then the pin after DIP locking seat 2 welding can be in the hole of 5 fretworks of bottom plate for 5 bottom surfaces of bottom plate are a plane, are convenient for fix on equipment or test desktop.

In embodiment 4, the substrate 1 and the bottom plate 5 are provided with waist-shaped notches 6 on two sides of the surface. Waist shape notch 6's effect lies in that the edge between them corresponds neatly about being convenient for when base plate 1 and bottom plate 5 bond, also is convenient for adopt fasteners such as screw to fix it on the equipment mesa, perhaps, directly fixes bottom plate 5 and equipment mesa through sticky mode, and the mode is nimble various.

The utility model discloses convenient operation is nimble, and reliable operation has improved product quality and production efficiency.
