Abstract
The utility model discloses a multipurpose testing clamp for a chip resistor, which belongs to technical equipment, and aims at providing the testing clamp with simple and convenient operation and capabilities of testing different electric performances including resistance, dielectric withstand voltage, temperature characteristic and power processing of different types of chip resistors. The testing clamp comprises a positioning component and a clamping device which are fixed on an insulated pedestal, wherein the positioning component includes two leaf springs (4) connected with a power supply; and the clamping device is composed of a support (2) fixed on the insulated pedestal (5), a metal pressing needle (1) arranged on the support, and a spring (3) placed between the pressing needle (1) and the support (2). The clamp for testing different electrical performances of the chip resistor has the advantages of simple structure, convenience in use, multiple purposes, high efficiency and the like.
Description
Technical field
The utility model relates to a kind of fixture of testing electronic element performance, relates in particular to a kind of for testing the fixture of the electrical quantitys such as chip resistor temperature characterisitic, dielectric withstanding voltage, Power Processing, positive negative temperature, TCR.
Background technology
For guaranteeing the q&r of resistance product, in chip resistor production run, need it to carry out the multinomial tests such as temperature characterisitic, dielectric withstanding voltage, Power Processing.At present, normally first Product jointing is carried out to every test to glass-fiber-plate again, this not only can destroy test product profile, it is scrapped, and efficiency is low, can not meet the needs of large-scale production.In addition, in the dielectric withstanding voltage test process of chip high-voltage resistor, need in resistor surface and two end electrodes, apply the alternating voltage of 900V, because chip resistor volume is little, there is no again desirable unit clamp in executing alive process, therefore have larger potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model aims to provide a kind of simple to operation, the chip resistor multi-usage test fixture that can detect multiple electrical properties such as the resistance of the chip resistor of Multiple Type, dielectric withstanding voltage, temperature characterisitic, Power Processing.
To achieve these goals, the utility model by the following technical solutions: its bag is fixed on setting element and the hold down gag on insulator foot; Described setting element is two spring leafs that are connected with power supply, described hold down gag by being fixed on support on insulator foot, be located at the metal pressing on this support, the spring between this pressing and support forms.
Spring leaf is inverted u-shaped structure.
Compared with the prior art, the utility model is owing to having adopted technique scheme, and two spring leafs that are inverted u-shaped structure of take are setting element, therefore can meet the positioning requirements of plurality of specifications chip resistor; And metal pressing both can be fixed measured resistance device by spring, thereby can realize, product is carried out to temperature characterisitic and Power Processing detection; When metal pressing is communicated with a utmost point of power supply, two spring leafs are when be communicated with another utmost point of power supply, can do product to carry out dielectric withstanding voltage test.The utlity model has that simple in structure, easy to operate, purposes is wide, efficiency advantages of higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view in Fig. 1.
In figure: metal pressing 1, support 2, spring 3, spring leaf 4, insulator foot 5.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
In Fig. 1～2, support 2 is fixed on insulator foot 5, and metal pressing 1 is located in the pilot hole of support 2, and spring 3 is fixed on metal pressing 1; Below this metal pressing, be two spring leafs 4 that are fixed on insulator foot 5 and are connected with power supply (not shown) respectively.In order to guarantee to compress reliably, spring leaf 4 adopts inverted u-shaped structures.
Claims (2)
1. a chip resistor multi-usage test fixture, wraps and is fixed on setting element and the hold down gag on insulator foot; It is characterized in that: described setting element is two spring leafs (4) that are connected with power supply, described hold down gag by being fixed on support (2) on insulator foot (5), be located at the metal pressing (1) on this support, the spring (3) being positioned between this pressing and support (2) forms.
2. chip resistor multi-usage test fixture according to claim 1, is characterized in that: spring leaf (4) is inverted u-shaped structure.
