The socket assembly A of the present invention comprises a bulb socket 310 to which a bulb 100 is connected and an assembly structure of a bulb socket housing 300 to which the bulb socket 310 is mounted.

The bulb socket housing 300 is integrally formed with a support portion 318 corresponding to the neck 170 of the bulb 100 around the opening portion into which the bulb is inserted.

In addition, the bulb socket 310 includes a grip piece 311 positioned in the bulb socket housing, a fixed body plate 313 in which the bulb is closely contacted, and a fixing piece 330 supporting the cable 200 integrally Respectively.

The grip pieces 311 formed on the bulb socket 310 are formed as a pair so as to be in point contact on both sides of the fixing groove 120 of the bulb 100.

The bulb 100 has a base 110 extending downward and a neck 170 formed at the bulb and base connection portion. A lead wire 190 and a grip piece 311 Are formed integrally with each other.

The first grip portion 311 is formed in a row and is provided so as to be in point contact with the fixing groove of the bulb. The grip portion of the first grip portion 311 has a first contact portion 311a, The second contact portions 311b are formed so as to face each other.

The body plate 313 is elastically provided with horizontal contact pieces 320 protruding from both side edges thereof and having a surface.

The body plate 313 is further provided with a support plate 345 having a surface on one side of the vertical contact piece, and the vertical contact piece 340 is elastically provided so as to be inclined downward.

Subsequently, the support portion 318 of the bulb socket housing 310 has a support hole formed to be supported by the neck of the bulb, or a structure of at least three protrusions spaced apart from each other so as to be in contact with the same circumference as the support hole Is selected and used.

Further, the grip piece 311 is configured so that the embossment 311a is integrally projected.

The operation of the present invention constructed as described above will be described.

2 to 8, when the base 110 formed on the lower side of the bulb 100 is inserted into the bulb socket housing 300, the bulb socket 300 The bulb and the bulb socket housing are coupled to each other by being press-fitted into the base portion 110 between the gripping pieces 311 of the pair of bolts.

At this time, the first and second contact portions 311a and 311b formed on a pair of grip pieces 311 are pressed against the fixing groove 120 of the base 110 to prevent the bulb from moving, The power source 311 is brought into contact with the lead wire 190 and energized.

On both sides of the fixing groove 120 of the base 110, the first contact portion 311a, which is in contact with the same inclination while making the point contact, and the second contact portion 311b, which contacts the different inclination, So that a firm adherence is maintained in the fixing groove.

At this time, if the bending angle of the first contact portion 311a protrudes inward to almost zero, the bulb 100 can be more firmly fixed.

The body plate 313 formed at one side of the grip piece 311 is formed in a terminal accommodating portion (not shown) formed in the bulb socket housing 300 when the bulb socket 310 is assembled to the bulb socket housing 300 So that the bulb socket is prevented from flowing.

The body plate 313 is further provided with a horizontal contact piece 320 or a vertical contact piece 340 so as to correspond to a width or a thickness corresponding to a side surface of the terminal accommodating portion, The bulb socket housing 300 prevents the bulb socket 300 from flowing to prevent bulb wobble or tilt, thereby preventing vibrations or bulb shorts caused thereby.

In addition, the lead wire and the bulb socket are connected to each other to prevent buring or arcing caused by incomplete connection of the connection portion.

That is, the body plate 313 of the present invention is closely attached in a state in which the horizontal contact pieces 320 protruding from both side ends of the body plate 313 are protruded under surface contact, .

The body plate 313 is further connected to a supporting plate 345 having a surface contact surface on one side of the vertical contact piece when the vertical contact piece 340 is elastically installed so as to protrude downward, It is brought into close contact with the surface to prevent the flow.

When the vertical contact piece and the horizontal contact piece are simultaneously installed, the body contact part 313 may be provided with a vertical contact piece and a horizontal contact piece. When the vertical contact piece and the horizontal contact piece are simultaneously installed, Thereby preventing the flow of the socket 310

An embossment 311a formed in the longitudinal direction of the grip piece 311 and protruding inward is formed to increase the elastic force of the grip piece 311 and to increase the elastic force of the grip piece 311 from the bulb 100 It can dissipate the conduction heat more effectively, thereby minimizing thermal deformation.

Subsequently, the bulb socket housing 310 is integrally formed with the support portion 318 so that the bulb is brought into close contact with the neck 318 of the bulb when connected to the bulb socket of the bulb socket housing, thereby preventing the bulb socket from flowing.

At this time, when the support portion 318 is selected from among the configurations of the support hole formed to be supported on the neck of the bulb or the configuration of at least three or more protruding jaws spaced so as to be in contact with the same circumference as the support hole, Or it is supported by a couple to prevent the flow.
