A plurality of lamps are installed in the backlight, and in order to control the plurality of lamps, a terminal of the backlight lamp and the like must be electrically connected to a printed circuit board provided with a control circuit.

The backlight lamp fixing socket is used to perform the above function. In the conventional backlight lamp fixing socket, a terminal of the backlight lamp is pushed into a fixed contact terminal of the socket contacting the terminal of the backlight lamp to connect the terminal to the terminal, and the lamp The terminal of was fixed.

This fixing socket is fixed to the chassis of the LCD. That is, they are put together in a chassis and fixed to the chassis by bolting or the like.

When the backlight lamp fixing socket is fixed to the chassis of the flat panel display device, when the bolt is coupled to each other, small tasks for fastening the bolts increase, resulting in a problem of inefficient work.

Accordingly, an object of the present invention is to provide a simple backlight lamp fixing socket to improve the convenience of assembly to improve the work efficiency.

The present invention has the following configuration in order to achieve the above technical problem.

The present invention relates to a socket for connecting a backlight lamp terminal to a circuit board and fixing the terminal of the backlight lamp used in a flat panel display device,

A housing 10 having an accommodation space 13 for accommodating a backlight lamp terminal therein;

And a contact terminal portion 20 for maintaining contact with the backlight lamp terminal in the accommodation space 13,

The housing has a rectangular cylindrical body portion 11, a locking plate 12 protruding to the side along the periphery of the body portion, and a locking plate extending upward from the lower portion of the body portion and protruding to the side from the body portion. It comprises a pair of engaging arms (15a, 15b) having elasticity extending up to and engaging projections (16a, 16b) protruding laterally from each of the engaging arms having an inclination toward the bottom.

In addition, in the present invention, the housing 10 passes through the through hole 31 formed in the chassis 30 provided in the flat panel display device, and the pair of coupling arms 15a and 15b elastically deform and the locking protrusions Passing through the through hole, the periphery of the through hole 31a of the chassis is positioned between the engaging protrusions and the engaging plate 12, the coupling between the chassis and the housing is configured to be maintained.

In addition, the chassis further comprises a coupling groove 32 on one side of the through hole,

The housing further includes an induction part 17 protruding on one side of the body part to form a rail.

The induction part 17 is guided to the coupling groove 32 so that the housing can be coupled to the chassis.

The present invention has the following effects by the above configuration.

In the present invention, the coupling arm formed in the housing passes through the chassis and is elastically coupled to the chassis. As a result, the backlight lamp fixing socket and the chassis can be coupled without a separate bolt coupling. Therefore, the work is simplified, the work efficiency is improved and the convenience of assembly is improved.

With reference to the drawings to be described in more detail through an embodiment of the present invention.

1 is an exploded perspective view of the present invention, Figure 2 is a front view of the present invention, Figure 3 is a front view of the present invention combined with the chassis.

As shown in FIG. 1, the present invention relates to a socket for fixing a terminal of a backlight lamp, and is largely composed of a housing 10 and a contact terminal portion 20.

The housing 10 is configured to be a body of the backlight lamp fixing socket, and has an accommodation space 13 formed therein to accommodate the terminal and the contact terminal portion 20 of the backlight lamp. It is a general shape and has a box shape with an empty inside.

The housing has a rectangular cylinder-shaped body portion 11, a locking plate 12 protruding laterally along the circumference of the body portion, and a locking plate extending upwardly from the lower portion of the body portion and protruding laterally from the body portion. It comprises a pair of engaging arms (15a, 15b) having elasticity extending up to and engaging projections (16a, 16b) protruding laterally from each of the engaging arms having an inclination toward the bottom.

The body portion 11 has a receiving space 13 is empty inside, it is formed in a rectangular cylinder shape. The body portion in the housing is a basic configuration forming a skeleton. All components of the housing extend from the body portion.

The housing has an opening 14 formed at the bottom thereof, and the opening is connected to the accommodation space 13. Therefore, when the contact terminal portion is accommodated in the accommodation space 13, the circuit board may be in contact with the contact terminal portion through the opening 14.

The locking plate 12 is formed and protrudes along the circumference of the body as shown in FIG.

The coupling arms 15a and 15b are a pair of components having elasticity extending from the lower portion of the body portion to the upper portion and extending from the body portion to the locking plate protruding to the side as shown in FIG. 2. This acts like a leaf spring in the housing and generates elasticity when engaging the chassis, which will be described later, so that the coupling with the chassis is maintained.

The locking protrusions 16a and 16b protrude to the side from each of the engaging arms and are formed to have an inclination toward the lower side. This allows the coupling arm to enter naturally without breaking when entering the chassis, and is configured to maintain the coupling after the coupling.

The contact terminal 20 is configured to maintain contact with the backlight lamp terminal in the accommodation space 13. As shown in FIG. 1, a terminal contact portion 21 having a shape such as a leaf spring is formed on the top to maintain contact with the backlight lamp terminal, and a circuit board can be held on the bottom to maintain contact with the circuit board. And a substrate contact portion 22 having a 'U' shape.

According to the present invention, the housing 10 passes through the through hole 31 formed in the chassis 30 of the flat panel display device, and the pair of coupling arms 15a and 15b elastically deform and the locking protrusions penetrate through the housing 10. Passing through the ball, the periphery of the through hole 31a of the chassis is positioned between the locking protrusions and the locking plate 12, so that the coupling between the chassis and the housing is maintained.

The backlight lamp fixing socket is coupled to the chassis 30 provided in the flat panel display device. The chassis 30 forms a skeleton in a display device. As shown in FIG. 1, the chassis is formed in a plate shape, and a through hole 31 in which the housing 10 is accommodated is formed. In addition, the coupling groove 32 to be described later is formed at one side of the through hole.

Meanwhile, the housing further includes an induction part 17 protruding from one side of the body part to form a rail as shown in FIG. 1. Accordingly, the induction part 17 is guided to the coupling groove 32 so that the housing can be coupled to the chassis.

As such, when the housing is coupled to the chassis, the through hole circumference 31a of the chassis is positioned between the engaging protrusions and the engaging plate 12 as shown in FIG. 3 to maintain the coupling between the chassis and the housing.

While the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the scope of the present invention is not to be construed as limited to such embodiments and / or drawings, but is determined by the matters set forth in the claims below. . In addition, it should be clearly understood that improvements, changes, modifications, and the like apparent to those skilled in the art described in the claims are included in the scope of the present invention.
