FIG. 1 is a perspective view showing an electrical contact terminal applied to FIG. 1, and FIG. 2 (b) is a sectional view taken along line bb of FIG. And Fig. 3 shows that the electrical contact terminal is applied to the metal case.

The electrical contact terminal 100 is flatly formed and packed in a reel carrier, supplied and vacuum-picked up from the surface of the electrical contact terminal 100. The electrical contact terminal 100 is forcibly inserted into a receiving groove formed on the surface of the electrically conductive object, And are further combined and mounted.

In this embodiment, the electrically conductive object is a metal case 10 of a mobile phone 1 made of a lightweight nonferrous metal such as aluminum, aluminum alloy, magnesium or magnesium alloy. As shown in Fig. 1, ) Further comprises a circuit board (20) and a cover (30).

In this embodiment, the inner surface of the case 10 is formed with an insulating coating layer for preventing corrosion and improving strength, but the insulating coating layer may not be formed.

In this example, an electrical contact terminal 100 is provided on the inner surface of the case 10, and an elastic clip 50 mounted on a conductive pattern of the circuit board 30, which is mounted on the circuit board 30, 100 are mechanically brought into contact with each other to electrically connect the circuit board 30 and the metal case 10.

A housing groove 12 is formed in the predetermined electrical contact portion of the case 10 and the electric contact terminal 100 is forcibly inserted into the housing groove 12 to be mounted. And is fixed to the case 10 by a bolt.

The receiving groove 12 is formed integrally with the case 10 by cutting the corresponding portion of the case 10 by CNC milling.

An elastic clip 50 is mounted on the circuit board 30 at a portion opposed to the electrical contact terminal 100 such as by soldering and mechanically brought into electrical contact with the electrical contact terminal 100 mounted on the case 10. [

2, the electrical contact terminal 100 includes a body 110 made of aluminum, an aluminum alloy, a magnesium or a magnesium alloy like the case 10, an intermediate layer 120 formed on the body 110, And a contact layer 130 formed on the contact layer 120.

The body 110 of the contact terminal 100 is made of the same or similar material as that of the case 10, so that electrical and chemical changes at the contact portion are small.

In this embodiment, the electrical contact terminal 100 is formed in a rectangular cross-sectional shape with a thickness of about 0.2 mm to 0.5 mm, and the length and width of the electrical contact terminal 100 are each about 1 mm to 4 mm, Do not.

The electrical contact terminal 100 may be circular in shape to facilitate machining and welding, and to provide various handling and applications. In this case, the electrical contact terminal 100 is easy to reel taping and easy to apply to various fields with one dimension.

The intermediate layer 120 may be formed of a nickel alloy plating layer such as a nickel plating layer or a nickel-palladium alloy, and the contact layer 130 may be formed of a gold alloy plating layer or a gold alloy plating layer such as a gold-cobalt alloy.

In particular, the contact layer 130 is a portion in electrical and mechanical contact with the resilient clip 50, and the hardness Vikers are greater than the hardness of the case 10, so that the contact terminal 100 is in mechanical contact with the resilient clip 50 Not only protects the case 10, but also serves to prevent corrosion caused by the environment.

The electrical contact terminal 100 may be formed by sequentially forming an intermediate layer 120 and a contact layer 130 on a wide plate-shaped raw material by plating, and then by pressing. Alternatively, the portion of the body 110 that is exposed by punching may be coated with a corrosion inhibitor that prevents corrosion due to the environment and can burn out at high temperatures during the welding operation and evaporate. Such anticorrosion agents may consist of a polymer coating that burns out at the welding temperature and leaves no residue after welding.

Alternatively, the intermediate layer 120 and the contact layer 130 may be formed by first forming the body 110 by first pressing the fabric, and then sequentially plating the entire surface.

As described above, the case 10 has a receiving groove 12 of a size corresponding to the electrical contact terminal 100, which may be approximately the same or slightly smaller than the dimensions of the electrical contact terminal 100. [

Therefore, the electrical contact terminal 100 can be fitted into the receiving groove 12 by a forced press-fitting method and physically engaged, so that the electrical contact terminal 100 can be prevented from being detached while the case 10 is moving.

The contact terminal 100 and the case 10 are made of a similar material in the process of forcibly fitting the contact terminal 100 into the case 10. However, the receiving groove 12 is a part of the case 10, The body 110 of the contact terminal 100 can be deformed. As the body 110 is deformed as described above, the side surface of the body 110 comes into close contact with the inner side wall of the receiving groove 12 to be physically coupled, and at the same time, electrically coupled.

Here, the electrical contact terminal 100 is forcibly fitted to the receiving groove 12 by physical force by a jig provided in the surface mounting apparatus or separately provided.

A C-cut can be applied to the lower edge of the body 110. The surface of the electrical contact terminal 100 is surface-mounted by a surface mounting apparatus, It can be easily inserted into the receiving groove 12 with a small force when the receiving groove 12 is inserted. In addition, a taper can be formed at the entrance edge of the receiving groove 12.

The thickness of the electrical contact terminal 100 is equal to or similar to the depth of the receiving groove 12 and is not easily separated by an external force after being received in the receiving groove 12. For example, the electrical contact terminal 100 may be inserted into the receiving groove 12 and may be maintained at the same horizontal level or slightly protruded from the receiving groove 12, so as to maintain the horizontal level so that the body 110 is not exposed. It is good to do.

Since the welding operation is performed in a state where the electrical contact terminal 100 is forcibly inserted into the receiving groove 12 and physically engaged with the receiving groove 12, it can be mounted at the correct position of the case 10.

The electrical contact terminals 100 are welded along the boundary between them in a state of being inserted into the receiving groove 12, and they are fused together with the case 10 integrally by, for example, laser welding or ultrasonic welding.

The welding may be continuous or discontinuous (point welding) at the gap portion of the body 110 and the case 10, and welding is performed at a small number of points when the adhesive is further applied, .

As described above, there is little impurities such as bubbles by welding along the boundary, and welding is performed reliably, thereby improving mechanical, chemical and electrical characteristics.

3, since the body 110 is formed of the same material or similar material as the case 10, the body 110 is melted by welding to form a single material weld 14, The electrical contact and the chemical reaction between the electrical contact terminal 100 and the case 10 do not occur, so that attenuation or distortion of the electrical signal is reduced and the occurrence of corrosion is small, The reliability of electrical and electrical coupling is improved.

Here, the similar material refers to a material having mechanical, chemical and electrical similar characteristics to the body 110 and the case 10 when the body 110 and the case 10 are melted and welded together.

In addition, since both the body 110 and the case 10 are made of a material having a low melting point, electric energy can be reduced during welding.

Fig. 3 shows that the electrical contact terminal is applied to the metal case.

The adhesive agent 13 is interposed between the lower surface of the body 110 of the electrical contact terminal 100 and the bottom of the receiving groove 12 so that the electrical contact terminal 100 can be securely fixed to the receiving groove 12.

A predetermined amount of adhesive 13 is discharged onto the bottom of the receiving groove 12 by dispensing or printing and then the body 110 is forcedly inserted into the receiving groove 12 so that the body 110 is bonded to the adhesive 13, To be bonded to the bottom of the receiving groove 12 by means of an adhesive. Alternatively, the lower surface of the body 110 may be immersed in a liquid adhesive so that the adhesive is adhered, and then press-fitted into the receiving groove 212.

The adhesive 13 may be electrically conductive and may be formed by mixing an electrically conductive powder such as copper, aluminum, silver, gold, or conductive carbon with an acrylic resin, an epoxy resin, a silicone rubber or the like having adhesive strength, The contact terminal 100 is bonded to the receiving groove 12.

Since the welding is performed while the electrical contact terminal 100 is forcibly inserted and physically engaged without applying or applying the adhesive agent 13 to the receiving groove 12, 100 may be mounted.

The elastic clip 50 mounted on the circuit board 30 by the solder 52 is in electrical contact with the contact layer 130 of the electrical contact terminal 100 in mechanical contact.

This embodiment can be modified in various ways. For example, the contact terminal 100 may be forcedly inserted into the receiving groove 12 to be physically coupled and welded by welding, or the contact terminal 100 may be forced into the receiving groove 12 A method of inserting and fixing the contact terminal 100 and a bottom surface of the receiving groove 12 with an adhesive 13 interposed therebetween and a method of using them in combination can be selectively applied.

4 (a) and 4 (b) show a mounting structure of an electrical contact terminal according to another embodiment of the present invention, respectively.

This embodiment applies the physical contact between the electrical contact terminal and the receiving groove and the adhesive bonding by the adhesive without welding due to the structural characteristics of the electrical contact terminal.

The electrical contact terminal 150 can be provided with a composite structure to serve also as a metal clip 50 mounted on the circuit board 30 so that a separate metal clip is mounted on the circuit board There is no need to do so.

It is possible to prevent the metal surface of the case 10 from being exposed to the outside by forming an insulating coating layer on the entire surface after the housing groove 12 is formed in the case 10 due to the structural characteristics of the electrical contact terminal.

The electrical contact terminal 150 is formed of a single body of metal formed by pressing and has a flat fixed portion 151 and a pair of protrusions 151 which are bent upward at both ends of the fixed portion 151, Elastically deforming portions 152 and 154 which are brought into close contact with each other and a contact portion 153 which extends from the deforming portion 152 and which is brought into contact with the conductive pattern of the circuit board 30 and elastically rotatable.

The fixing portion 151 of the electrical contact terminal 150 is substantially rectangular in plan view like the receiving groove 12 and the deformed portions 152 and 154 are integrally formed at both ends in the longitudinal direction, The fixing portion 151 has a planar shape that is slightly smaller than the bottom of the receiving groove 12.

The contact portion 153 is formed so as to be smaller than the width of the receiving groove 12 so as not to contact the inner wall of the receiving groove 12 in order to rotate elastically irrespective of the receiving groove 12, The inner wall of the receiving groove 12 is not disturbed.

When the electrical contact terminal 150 is forcibly inserted into the receiving groove 12, the deformed portions 152 and 154 are elastically deformed, that is, pressed inward in the longitudinal direction, And is physically and electrically coupled to the inner wall.

The lower surface of the fixing portion 151 of the electrical contact terminal 150 is held by the electrically conductive adhesive agent 13 in the state where the deformed portions 152 and 154 are in close contact with the left and right inner side walls of the receiving groove 12, Glued to the bottom of the groove 12 and mechanically and electrically coupled.

Although the deforming portions 152 and 154 are formed at both ends in the longitudinal direction in this embodiment, it is of course possible to form them at both ends in the width direction without manufacturing problems.

The fixing portion 151 of the electrical contact terminal 150 is made of a metal having a high elasticity and has a chamfered portion C The case 10 may be a file so that -Cut is formed, but the present invention is not limited thereto.

The contact terminal 150 is forcibly inserted into the accommodating groove 12 so that the resiliently deformed portions 152 and 154 of the contact terminal 150 are deformed and come into close contact with the inner wall of the accommodating groove 12, And because of the nature of the structure, welding is not easy. Therefore, the electrical bonding adhesive 13 is applied to reinforce physical bonding by forced insertion.
