Description

A measuring socket with sheet type contact pin}

The present invention relates to a socket for measuring electronic components used to produce electronic components such as oscillators and to measure their characteristics. More specifically, the lead of the electronic components can be easily inserted by a wide pinhole, The present invention relates to a socket for measuring an electronic component having a plate-shaped contact pin having a long contact force and elastic force with a lead by a plate-shaped contact pin.

In a test for analyzing various characteristics of an electronic component such as a crystal oscillator, an IC socket, which is an intermediate medium for electrically connecting a substrate and an electronic component to be tested to the substrate, is required. The protruding end of the contact pin of the IC socket is fixed to the board by soldering the IC socket. The IC socket is installed, and the electronic socket is mounted on the IC socket, subjected to a predetermined test, and then taken out. Then, a new electronic component is mounted and tested. .

In such an IC socket, a plurality of pin holders having contact pins in contact with the leads of an electronic component are inserted at both edges of the rectangular main body such that the protruding ends thereof protrude downward from the main body. In the pin hold, the insertion hole into which the lead is inserted is formed to be shallower than the length of the lead.

Therefore, when the projecting end of the pin hold is soldered to the substrate, and the electronic component is inserted into the IC socket, it can be operated in the same manner as that mounted on the substrate.

That is, the electronic component is periodically inserted into or extracted from the IC socket. When inserted, the lead of the electronic component comes into contact with a contact pin provided in the pin hold of the IC socket. Insertion and extraction of the first few times of the electronic component is not good, but as the insertion and extraction is repeated, the contact pin of the IC socket increases the number of mechanical contact with the lead of the electronic component, there is a problem that the contact pin wears Due to the wear, the IC socket is loosened, resulting in poor contact, thereby making it difficult to accurately measure the characteristics and causing waste of resources by replacing the IC socket.

In addition, the conventional pin-hold structure has a problem in that the upper inlet portion is narrow, so that if the lead of the electronic component is bent at least, it can not be easily inserted, and the lead is severely bent. In addition, there is a problem in that the lead is bent because the depth of the insertion hole into which the pin holder lead is inserted is shallower than the length of the lead.

The object of the present invention is to solve the conventional problems as described above and to make a structure capable of automation by a robot, the main body is in contact with the bottom surface of electronic components such as oscillator, the arm of the robot is inserted into the upper surface of the main body To form mounting grooves for mounting electronic components, widen and deepen the depth and depth of the main body pin hole into which contact pins are inserted, so that the lead of the electronic parts can be easily inserted. The present invention provides a socket for measuring an electronic component having a plate-shaped contact pin, which improves work efficiency and extends life by reducing wear of contact pins and loss of elastic force.

A contact pin 6 bent at an obtuse angle into which the lead 4 of the electronic component 3 is inserted into and contacted with the pin 4, and a plurality of pin holders 2 are installed to penetrate through both edges of the rectangular body 7. In the electronic component measuring socket 100, a rectangular main body 7 is provided with a plurality of pinholes 8 deeper than the length of the lead 4 of the electronic component 3 at regular intervals, and the pinholes 8 are formed. A mounting groove 9 into which an arm of an automated robot is inserted is formed between the upper and lower ends of the long rectangular plate body gold-plated with phosphor bronze in the pinhole 8 to be bent at an acute angle to form an elastic part 10. A pair of contact pins 6 in which the auxiliary elastic pieces 11 protrude from the inside of the elastic part 10 may be installed with the elastic part 10 facing each other. It shall be.

In the drawing, reference numeral 12 is a substrate on which the socket 100 is installed.

According to the present invention, the depth of the insertion hole 5 is deeper than the length of the lead 4 so that the bottom surface of the electronic component 3 is in stable contact with the top surface of the socket 100, and the contact pin 6 is shaped. And the material is characterized by long lasting while having a sufficient elastic force.

First, the contact pin (6) used in the socket 100 of the present invention is used for the spring and is a flat plate of phosphor bronze, which is an alloy with phosphorus added to bronze, using electronic materials ( Repetitive contact with the lead 4 of 3) maintains elastic force for a long time and minimizes contact resistance.

In addition to the material, the contact pin 6 of the present invention has a shape of a leaf spring by bending the upper end of the phosphor bronze plate to form an elastic portion 10 to form an acute angle with another portion, as shown in FIG. As shown in FIG. 6, the conventional contact pin 6 has a high elastic force as compared with the curved bent angle.

In addition, an auxiliary elastic piece 11 protrudes inside the elastic part 10 of the contact pin 6 of the present invention. The auxiliary elastic piece 11 serves to assist the spring action of the elastic portion 10, when the elastic portion 10 is pressed by the lead 4, the elastic portion 10 is attached to the auxiliary elastic piece 11 In this case, the auxiliary elastic piece 11 also serves as a spring.

After the pair of contact pins 6 having the above-described materials and structural features are inserted and installed in the pinhole 8 formed in the main body 7 of the socket 100, the lower end of the contact pins 6 is attached to the substrate 12. It is fixedly installed by soldering.
