Description

Contactor to prevent electric shock

The present invention relates to an electric shock-proof contactor, and more particularly, to an electric shock-proof contactor capable of preventing a user from electric shock due to a leakage current caused by electric power introduced from the outside.

Various components are integrated into a multifunctional electronic device such as a smart phone according to its function. In addition, the electronic device is provided with an antenna capable of receiving various frequency bands such as a wireless LAN, Bluetooth, and a Global Positioning System (GPS). A part of the antenna may be installed as a built-in antenna in a case constituting each of the electronic devices. Therefore, a contactor is provided for electrically connecting the antenna installed in the housing to the built-in circuit board of the electronic device.

In recent years, with increasing attention to the delicate appearance and durability of electronic devices, the supply of terminals including a case made of a metal material is increasing. That is, the supply of smart phones in which the bezel is made of metal or the rest of the case except the front image display part is made of metal is increasing.

However, when the case is made of a metal material, static electricity with a high voltage may be momentarily introduced through the external metal case, and then, static electricity may be introduced into the internal circuit via the contactor to damage the circuit.

In addition, when a charger in which an overcurrent protection circuit is not installed is used in an electronic device including a metal case, an electric shock may occur when the smart phone is used during charging. That is, when a non-genuine charger or an unqualified charger is used to charge a smart phone, the current may move along the ground of the internal circuit and be transmitted to a case in contact with the user. Therefore, when a user comes into contact with the housing during charging of the electronic device, the user may have an electric shock accident.

Therefore, when it is intended to provide a contactor for electrically connecting a housing to an internal circuit, it is necessary to provide a contactor capable of preventing the internal circuit from being damaged and preventing electric shock from a user.

In the electrostatic discharge protection layer 430, a through hole may be defined in a region of the insulating sheet in which the first internal electrode 423 and the second internal electrode 424 overlap each other at respective formation positions, and then a thick A thick film printing process fills the through hole with an electrostatic discharge protection material to form an electrostatic discharge protection layer 430.

Thereafter, the first internal electrode 423 and the second internal electrode 424 are respectively disposed on one side surface and the other side surface of the insulating sheet to form an electrostatic discharge protection layer 430.

As shown in FIGS. 1 and 4A, the electrostatic discharge protection layer 430 may be provided as one layer including a material containing an electrostatic discharge protection material. For example, the ESD protection material may include a conductive ceramic and an insulating ceramic, and the ESD protection layer 430 may be formed using a mixture in which the conductive ceramic and the insulating ceramic are mixed with each other. In this case, the electrostatic discharge protection layer 430 may be formed by mixing a conductive ceramic and an insulating ceramic at a mixing ratio of, for example, 10:90 to 90:10. As the mixing ratio of the insulating ceramics increases, the discharge initiation voltage increases. In addition, as the mixing ratio of the conductive ceramics increases, the discharge start voltage decreases. Therefore, the mixing ratio of the conductive ceramic and the insulating ceramic is adjusted to obtain a predetermined discharge starting voltage.

In addition, the electrostatic discharge protection layer 430 may have a predetermined laminated structure in which a conductive layer and an insulating layer are laminated. That is, the conductive layer and the insulating layer may be laminated at least once to be separated from each other, thereby forming the electrostatic discharge protection layer 430. For example, the ESD protection layer 430 may have a two-layered structure using conductive layers 431a and 431b and an insulating layer 432. Alternatively, the conductive layers 431, the insulating layers 432, and the conductive layers 431 may be alternately disposed to form a three-layered structure. In addition, the conductive layers 431a and 431b and the insulating layer 432 may be laminated several times to form at least a three-layer structure. For example, as shown in (b) of FIG. 4, three layers having a first conductive layer 431a, an insulating layer 432, and a second conductive layer 321b laminated therein may be formed as described in the first modified example. Structure of the electrostatic discharge protection layer 430.

As another example, the ESD protection layer 430 may further include an air gap in a predetermined region of the ESD protection layer 430. For example, an air gap may be defined between layers in which a conductive material and an insulating material are mixed with each other or between a conductive layer and an insulating layer. That is, the first mixed layer, the air gap, and the second mixed layer in which the conductive layer and the insulating material are mixed with each other may be laminated, or the conductive layer, the air gap, and the insulating layer may be laminated. For example, in the latter case, as shown in FIG. 4 (c), the first conductive layer 431a, the first insulating layer 432a, the air gap 433, the second insulating layer 432b, and the second conductive layer 431b is laminated to form an ESD protection layer 430. That is, the insulating layers 432a and 432b may be disposed between the conductive layers 431a and 431b, and the air gap 433 may be defined between the insulating layers 432a and 432b.

In the electrostatic discharge protection layer 430 according to the first to third exemplary embodiments, an electrostatic discharge protection material may be separately filled into the through holes to form the electrostatic discharge protection layer 430. However, like the third modified example shown in (d) of FIG. 4, only the air gap may be provided without including a conductive material and an insulating material.

A firing process may be performed after the polymer material is filled, and then the polymer material may be removed to form an air gap 433.

When an overvoltage is introduced, the conductive layers 431a and 431b of the ESD protection layer 430 can reduce the energy level to prevent structural breakdown of the electric shock protection device due to the overvoltage. The conductive material forming the conductive layers 431a and 431b may be a conductive ceramic. The conductive ceramic may be a mixture including at least one of La, Ni, Co, Cu, Zn, Ru, Ag, Pd, Pt, W, Fe, and Bi.

An insulating material mixed with a conductive material can be used as a discharge inducing material and as an electrical barrier with a porous structure. The insulating material may be an insulating ceramic. The insulating ceramic may include a ferroelectric material having a dielectric constant of approximately 50 to approximately 50,000. For example, the insulating ceramic may be a dielectric material powder such as a multilayer ceramic chip capacitor (MLCC), BaTiO ₃ , BaCO ₃ , TiO ₂ , Nd, Bi, Zn, and Al ₂ O ₃ . A mixture of at least one. The insulating layer 432 may have a porous structure in which a plurality of pores each having a size of approximately 1 nanometer (nm) to approximately 5 micrometers ( μm ) are formed to have a size of 30% to 80 Porosity in%. That is, although the insulating layer 432 is made of an electrically insulating material from which current cannot flow, the current can flow through the pores because the pores are formed. Here, when the size of the pores is increased or the porosity is increased, the discharge start voltage may be decreased. On the other hand, when the size of the pores is reduced or the porosity is decreased, the discharge starting voltage may be increased. However, if the size of the pores exceeds 5 micrometers or the porosity exceeds 80%, it may be difficult to maintain the structure of the electrostatic discharge protection layer 430. Therefore, in order to maintain the structure of the electrostatic discharge protection layer 430, the discharge start voltage can be adjusted to adjust the size and porosity of the pores of the insulating layer 432.

In addition, the resistance of the insulating layer 432 may be smaller than that of the insulating sheet due to the presence of the fine pores, and a partial discharge may be performed by the fine pores. That is, fine pores are formed in the insulating layer 432, and thus partial discharge is performed by the fine pores.
