Specifically, when the core part 110' and the shield part 130' are compressed by applying pressure in the longitudinal direction while contacting the conductor, the conductive particles contained in the longitudinal direction contact each other and impart electrical conductivity in the longitudinal direction. can do. In the contactor 100' according to the present invention, electrical conductivity can be further increased by protruding the core part 110' and the shield part 130' in an axial direction relative to the insulating part 120'.

For example, in the contactor 100" according to the present invention shown in FIG. 4, the core portion 110" protrudes more than other components, that is, the cross-sectional shape of the contactor 100" directly contacting the conductor. can be formed small to correspond to fine pitch pads or terminals, and when assembling with counterparts, the contact area can be widened and the shape can be varied. The contactor 100 "shown in FIG. By designing the diameter of both ends to be small, interference with neighboring components can be avoided and leakage current between adjacent pins can be minimized. Therefore, the contactor 100" according to the present invention enables close coupling between conductors and allows each contactor 100" to operate individually and accurately, thereby improving the precision between conductors.

The core part 110, the insulation part 120, and the shield part 130 according to an embodiment of the present invention have at least one of physical properties including hardness, Young's modulus, and resistivity. They can be designed differently.

For example, the core part 110 or the shield part 130 in direct contact with the terminal is designed to have higher hardness and elastic modulus than other configurations, so as to improve precision during connection, as well as to prevent deformation or deformation due to repeated use. damage can be prevented.

In addition, the core part 110 and the shield part 130 according to an embodiment of the present invention may be designed to have different properties (eg, material, size, density, etc.) of the conductive particles contained therein.

For example, in relation to the material of the conductive particles described above, the core part 110 or the shield part 130 may apply nickel particles for effective alignment of the conductive particles, and when there is a need to improve electrical conductivity. Copper particles can be applied. When silica plating particles are applied, there is an advantageous effect on weight reduction.

For another example, regarding the size of the conductive particles, large-sized conductive particles are easy to process and process and have excellent electrical conductivity, and small-sized conductive particles are relatively uniform even inside a member with a fine diameter. It can be evenly distributed to increase the hardness or modulus of elasticity of the member. Considering these characteristics, the contactor 100 according to the present invention is designed with different materials, sizes, and densities of the conductive particles included in the core part 110 and the shield part 130, respectively, so that each hardness or modulus of elasticity is can be designed differently.

As described above, the contactor 100 according to the present invention can satisfy various design requirements of the probe pin by designing the physical properties of the core part 110 and the shield part 130 differently from each other. That is, the core part 110 and the shield part 130 having different physical properties may be formed corresponding to a section requiring excellent hardness and a section allowing elastic deformation.

In addition, effective interconnection can be achieved even if there is a difference in tolerance or shape of the contact surfaces.

5 is a view showing a method of manufacturing a contactor according to the present invention described above. The method of manufacturing a contactor (S100) is to form a shield part by using a contactor mold in which a contactor cavity is formed as shown. Step S110, forming an insulating part (S120), and forming a core part (S130) may be included. Here, the contactor mold may be made of non-magnetic metal or resin. For example, it may include aluminum (Al) and torlon. According to the present invention, since the contactor can be manufactured using a single mold without using molds for each of the shield part, the insulation part, and the core part, the cost, time, and effort required to manufacture the contactor are reduced. can save

For example, in the step of forming the shield unit (S110), the shield unit that contains conductive particles and is elastically deformable may be formed on the inner circumferential surface of the contactor cavity. In the step of forming the insulating part (S120), an elastically deformable insulating part may be formed on the inner circumferential surface of the shield part. In addition, in the step of forming the core part (S130), the inner circumferential surface of the insulating part may contain conductive particles and form an elastically deformable core part. Accordingly, a contactor formed of a shield portion, an insulation portion, and a core portion sharing a central axis can be manufactured using a single contactor mold.

Finally, a step of separating the contactor manufactured from the contactor mold (S140) may be further included.

6 to 14 are views showing each step of a method of manufacturing a contactor.

First, with reference to FIGS. 6 to 8 , a step of forming the shield unit will be reviewed.

Forming the shield part may include coupling the contactor mold 210 and the concentric pin 311 of the shield part ( S111 ). The contactor mold 210 and the shield portion concentric pin 311 may be coupled by inserting the shield portion concentric pin 311 into the contactor cavity 211 , for example. Specifically, as shown in FIG. 6, when the contactor mold 210 is stacked at an appropriate position on the shield pin jig 310 on which the shield concentric pin 311 is formed, the shield concentric pin 311 forms the contactor cavity. (211) can be inserted inside. In this case, since the diameter of the concentric pin 311 of the shield part is smaller than that of the cavity 211 of the contactor, a predetermined space may be formed between the cavity 211 of the contactor and the concentric pin 311 of the shield part.

The shield part containing the conductive particles 111 in the space formed between the contactor cavity 211 and the shield part concentric pin 311 in a state in which the contactor mold 210 and the shield part concentric pin 311 are coupled. Filling the liquid phase 130a (S112) may be performed.

When the liquid phase 130a of the shield part is filled in the space formed between the contactor cavity 211 and the concentric pin 311 of the shield part, a hardening step ( S113 ) may be performed as shown in FIG. 7 .

For the curing step, a mold mold 220 having a plurality of magnetic pads 221 disposed at regular intervals may be used. The magnetic pad 221 is made of, for example, a magnetic metal such as nickel (Ni), a nickel-cobalt alloy (NiCo), and iron (Fe), and the mold mold 220 is formed of a weak magnetic material, so that the magnetic pad ( 221) can be induced to concentrate the magnetic force.

In the curing of the liquid phase of the shield unit ( S113 ), the mold frame 220 on which the magnetic pad 221 is formed may be aligned so that the magnetic pad 221 can correspond to the position of the contactor cavity. For example, as shown in FIG. 7 , the mold mold 220 may be brought into close contact with the contactor mold 210 so that the contactor cavity is sealed by the magnetic pad 221 . At this time, the mold frame 220 may be provided on one side of the contactor mold 210 and the other side opposite to the contactor mold 210, and on the other side, the magnetic pad 221 forms a contactor cavity with the shield pin jig 310 interposed therebetween. It can be arranged in a position corresponding to. In addition, at least one of predetermined heat, pressure, and magnetic force may be applied to the liquid phase of the shield unit through the mold frame 220 .

When any one of predetermined heat, pressure, and magnetic force is applied to the liquid phase of the shield part, the liquid phase of the insulating part may be hardened through a phase change.

When the liquid phase of the shield part is completely cured, as shown in FIG. 8 , a step of separating the concentric pins of the shield part from the contactor mold 210 may be performed. In this case, the concentric pins of the shield unit may be removed while the shield unit 130 is formed on the inner circumferential surface of the contactor cavity. The shield unit 130 from which the shield unit concentric pin is removed may pass through the shield unit in the axial direction and have an inner space having a shape corresponding to the shield unit concentric pin.

Meanwhile, the contactor mold 210 may be provided as a first mold 210a and a second mold 210b configured to be coupled/separated. Further, the contactor cavity 211 may be provided as a first cavity 211a formed in the first mold 210a and a second cavity 211b formed in the second mold 210b.

At this time, the forming of the shield part is a step of inserting a part of the shield part concentric pin 311 into the first cavity 211a, a space formed between the first cavity 211a and the shield part concentric pin 311. Filling the shield part liquid phase 130a containing the conductive particles 111 in the second mold phase 210a by inserting the remaining part of the shield part concentric pin 311 into the second cavity 211b. stacking (210b), filling the space formed between the second cavity (211b) and the concentric shield pin (311) with the shield liquid phase (130a), and curing the shield liquid phase (130a). can do.

In this way, if the contactor mold 210 can be separated into the first mold 210a and the second mold 210b, the contactor manufactured from the contactor mold can be easily separated, and the contactor is damaged at this time. can make it not happen. In addition, as examples of the first mold 210a and the second mold 210b, the contactor mold 210 may include three or more molds.

9 to 11 are diagrams illustrating steps of forming an insulator.

Forming the insulator may include coupling the contactor mold and the concentric pin of the insulator (S121). The contactor mold 210 and the concentric pin 321 may be coupled to each other by inserting the concentric pin 321 into the inner surface of the shield formed in the contactor cavity, that is, the inner circumferential surface of the shield. there is.

Specifically, as shown in FIG. 9, a shield in which an insulator concentric pin 321 is formed in a contactor cavity while an insulator pin jig 320 having an insulator concentric pin 321 and a contactor mold 210 are laminated. It can be inserted into the interior of the part. At this time, the diameter of the concentric pin 3221 of the insulator is smaller than the diameter of the concentric pin of the shield part, so that a predetermined space may be formed between the inner circumferential surface of the shield part and the concentric pin 321 of the insulator.

In a state in which the contactor mold and the concentric pin of the insulator are coupled, the step of filling the liquid phase of the insulator in a space formed between the inner circumferential surface of the shield and the concentric pin of the insulator (S122) may be performed.

When the liquid phase 120a of the insulating part is filled in the space formed between the inner circumferential surface of the shield part and the concentric pin 321 of the insulating part, a step of curing it may be performed as shown in FIG. 10 .

In the step of curing the liquid phase of the insulating part ( S123 ), the mold frame 220 on which the magnetic pad 221 is formed may be aligned so that the magnetic pad 221 can correspond to the position of the contactor cavity. For example, as shown in FIG. 10 , the mold mold 220 may be brought into close contact with the cavity mold 210 so that the contactor cavity is sealed by the magnetic pad 221 . At this time, the mold frame 220 may be provided on one side and the other side of the contactor mold 210, respectively, and the magnetic pad 221 on the other side corresponds to the contactor cavity with the insulator pin jig 320 interposed therebetween. position can be arranged. In addition, at least one of predetermined heat and pressure may be applied to the liquid phase of the insulation through the mold mold 220 . At this time, the magnetic pad 221 may only seal the contactor cavity and may not apply magnetism to the liquid phase of the insulating part through the mold.

When at least one of predetermined heat and pressure is applied to the liquid phase of the insulating part, the liquid phase of the insulating part may be formed integrally with the shield part while being cured through a phase change.

When the liquid phase of the insulating part is completely cured, as shown in FIG. 11 , a step of separating the concentric pin of the insulating part from the contactor mold (S124) may be performed. In this case, the concentric pins of the insulating part may be removed while the insulating part 120 is integrally formed on the inner circumferential surface of the shield part 130 . The insulation unit 120 from which the insulation concentric pin is removed may penetrate the insulation unit 120 in the axial direction and have an inner space having a shape corresponding to that of the insulation unit concentric pin.

12 to 14 are diagrams illustrating steps of forming a core part.

As shown in FIG. 12 , the forming of the core part may include filling the insulating part with a liquid core part containing conductive particles ( S132 ).

When the core part liquid phase 110a is filled in the insulation part 120, a step of hardening it may be performed as shown in FIG. 13 .

In the step of curing the liquid phase of the core part ( S133 ), the mold frame 220 on which the magnetic pad 221 is formed may be aligned so that the magnetic pad 221 can correspond to the position of the contactor cavity. For example, as shown in FIG. 13 , the mold mold 220 may be brought into close contact with the cavity mold 210 so that the contactor cavity is sealed by the magnetic pad 221 . In this case, the mold frame 220 may be provided on one side and the other side of the contactor mold 210, respectively. In addition, at least one of predetermined heat, pressure, and magnetic force may be applied to the liquid phase of the core part through the mold mold 220 .

When at least one of predetermined heat and pressure is applied to the liquid phase of the core part, the liquid phase of the core part may be formed integrally with the insulating part while hardening through a phase change.

The conductive particles may be axially aligned by a magnetic force applied through a mold frame, preferably a magnetic pad. The conductive particles may contact each other to impart conductivity in the axial direction to the core portion. When pressure is applied to the core part in the axial direction to inspect the test object, which is an electrical element, the core part is compressed and the conductive particles come closer to each other, so that the axial electrical conductivity of the core part can be further increased.

When the liquid phase of the insulation is completely cured, as shown in FIG. 14 , a step of separating the contactor 100 from the contactor mold 210 ( S140 ) may be performed. Separation of the contactor may be performed by separating the shield part from the inner circumferential surface of the contactor cavity.

In the above description, steps S110 to S140 may be further divided into additional steps or combined into fewer steps, depending on an implementation example of the present invention. Also, some steps may be omitted as needed, and the order of steps may be switched.
