On the outer surface of the lamp holder housing 51 is formed a stepped surface 59 which is relatively more protruded. The step surface 59 is provided with a seal stopper 61 protruding perpendicularly. Two seal stoppers 61 are formed, one on each of the top and bottom surfaces of the stepped portion 59 with reference to FIG. 2. However, the present invention is not limited thereto and may be formed in various numbers and positions. The seal stopper 61 is for preventing the seal member 67 from being coupled to the lamp holder housing 51.

A ramp stopper 63 is formed on the stepped surface 59. The lamp stopper 63 is formed to protrude perpendicularly from the step surface 59. When the lamp stopper 63 is mounted to the lamp holder 50, the lamp stopper 63 serves to limit the movement of the lamp so that the lamp is not excessively inserted. At this time, the lamp stopper 63 is formed to a height that protrudes more than the height of the sealing member 67, even if the sealing member 67 to be described later is provided between the lamp holder housing 51 and the lamp body.

A plurality of locking projections 65 are formed around the stepped surface 59 of the lamp holder housing 51. The locking protrusion 65 is formed to protrude from the step surface 59. A plurality of the locking projections 65 are formed at symmetrical positions of the stepped surface 59. The position where the locking projections 65 are formed is formed on the left side, that is, biased toward the wire guide 71 to be described later than the seal stopper 61. The locking protrusion 65 is a portion to which the hook hook 83 of the rear holder 80 to be described later serves to couple the lamp holder 50 and the rear holder 80.

At this time, the locking projection 65 is formed with a guide slope 66 to be inclined downward toward the rear end of the lamp holder housing 51. This is for the hook hook 83 of the rear holder 80 to be easily coupled to the locking projection (65).

The lamp holder housing 51 is equipped with a sealing member 67. The seal member 67 has a waterproof function between the lamp holder housing 51 and a lamp mounted thereto, and corresponds to an outer surface of the lamp holder housing 51 adjacent to the seal stopper 61. Is formed. The seal member 67 is preferably formed of an elastic material such as rubber.

Meanwhile, a wire guide 71 is formed in the lamp holder housing 51 to extend from one end thereof. The wire guide 71 is formed integrally with the lamp holder housing 51, and is formed in a cylindrical shape extending in a longitudinal direction from one side of the lamp holder housing 51.

Insertion hole 72 is formed in the wire guide 71 so that one side thereof is opened in the longitudinal direction of the lamp holder housing 51. A coupling boss 91 to be described later is inserted through the insertion hole 72. The wire connected to the terminal extends to the outside of the rear holder 80 through the coupling boss 91 inserted into the insertion hole 72. To this end, the insertion hole 72 is formed in a size and shape corresponding to the outer circumferential surface of the coupling boss 91.

Coupling slits 73 are formed on the outer circumferential surface of the wire guide 71. The coupling slit 73 is formed such that a portion of the outer circumferential surface of the wire guide 71 is recessed, and the coupling protrusion 93 to be described later is coupled thereto. To this end, the position and the number of the coupling slit 73 are determined according to the position and the number of the corresponding coupling protrusion 93. In the present embodiment, the coupling slits 73 are formed in pairs at positions symmetrical to each other on the outer circumferential surface of the wire guide 71. In this case, the width m of the coupling slit 73 is formed to correspond to the width n of the coupling protrusion 93. This is to allow the coupling protrusion 93 and the coupling slit 73 to be firmly fixed to each other without being spaced apart from each other.

Next, the configuration of the rear holder 80 mounted on the lamp holder housing 51 will be described. The rear holder body 81 forms a skeleton of the rear holder 80. The rear holder body 81 is formed of an insulating material, and is made of an insulating material such as the lamp holder housing 51 of the lamp holder 50. The rear holder 80 is mounted on the rear end of the lamp holder 50 to prevent the wire connected to the terminal of the lamp holder 50 from being separated by an external force applied from the outside.

A hook hook 83 is provided to surround the leading edge of the rear holder body 81 forming a skeleton of the rear holder 80. The hook hook 83 is symmetrically disposed at the center of the rear holder 80. The hook hook 83 is provided with a hook slot 84 on which the locking projection 65 is seated. The hook hook 83 is hooked to the locking protrusion 65 when the lamp holder 50 and the rear holder 80 are coupled to each other.

Meanwhile, when the lamp holder 50 and the rear holder 80 are coupled to each other, the front end of the hook hook 83 extends to a position corresponding to the seal stopper 61. This is to allow the tip of the hook hook 83 to serve to prevent the seal member 67 from being pushed. That is, the hook hook 83 serves to support the seal member 67 together with the seal stopper 61 at both side portions of the lamp holder housing 51.

A handle 85 is formed at the rear end of the rear holder body 81. The handle portion 85 is formed integrally with the rear holder body 81, and has a size enough to be gripped by an operator and has a substantially flat hexahedral shape.

Wire channels 87 are formed long at both sides of the handle 85. The wire channel 87 is opened to both sides of the handle portion 85. The wire channel 87 is connected to the terminal and serves to guide the wire extending to the rear of the lamp holder 50. To this end, the direction in which the wire channel 87 is opened is in both directions of the rear holder 80.

A coupling boss 91 is formed at the front end of the rear holder body 81 to extend to be connected to the wire channel 87. The coupling boss 91 is formed in a substantially hollow cylindrical shape. The coupling boss 91 is inserted into the lamp holder housing 51 through the insertion hole 72 so that the front end of the coupling boss 91 supports one side of the terminal so that the terminal supports the lamp holder. It serves to be more firmly fixed to the interior of the housing (51). In addition, the coupling boss 91 serves to prevent the wire seal provided in the wire connected to the terminal from being pushed to the rear of the lamp holder housing 51 in the waterproof lamp holder 50.

One side of the coupling boss 91 is opened to form an evacuation slit 92. In this embodiment, the avoidance slit 92 is formed to open in the longitudinal direction of the coupling boss 91 is cylindrical. The avoidance slit 92 is a portion for allowing the wire extending to the rear of the lamp holder housing 51 to pass therethrough. That is, even when the rear holder 80 is coupled to the lamp holder housing 51 while the wire is connected, the wire is not hindered by the rear holder 80 and the rear holder through the avoidance slit 92. It may extend rearward of 80. In addition, the avoidance slit 92 also serves to allow the coupling boss 91 is elastically deformed and easily coupled to the wire guide 71.

Coupling protrusions 93 are formed on the outer circumferential surface of the coupling boss 91. The coupling protrusion 93 is formed to protrude from the outer circumferential surface of the coupling boss 91. In the present embodiment, the coupling protrusions 93 are formed at positions symmetrical with respect to the outer circumferential surface of the coupling boss 91 except for the opened one side, and three coupling protrusions 93 are formed on the outer circumferential surface of the coupling boss 91. The coupling protrusion 93 is coupled to the coupling slit 73 of the wire guide 71 to prevent the left and right or up and down flow of the rear holder 80 mounted on the lamp holder 50. In this case, the width m of the coupling slit 73 is formed to correspond to the width n of the coupling protrusion 93. Therefore, the coupling protrusion 93 is tightly coupled so as not to generate a gap in the coupling slit 73.

On the other hand, the lamp (not shown) generates power by receiving power, and the front end of the lamp holder 50 is inserted into the lamp body portion at the rear end. The lamp body (not shown) is provided with a hanger jaw (not shown) to which the coupling lever 55 is coupled.

Next, the operation of the preferred embodiment of the lamp holder assembly according to the present invention will be described in detail.

The rear holder 80 is pushed toward the rear end of the lamp holder housing 51.

As a result, the coupling boss 91 is inserted into the wire guide 71 through the insertion hole 72. At this time, the coupling boss 91 is elastically deformable by the opened one side. Therefore, the coupling boss 91 may be easily inserted into the wire guide 71 in a state in which a wire connected to the terminal extends to the outside.

When the coupling boss 91 is inserted into the wire guide 71, the coupling protrusion 93 is coupled to the coupling slit 73. At this time, since the width (m) of the coupling slit 73 corresponds to the width (n) of the coupling protrusion 93, the coupling protrusion 93 is in close contact with each other in the state coupled to the coupling slit (73).

Meanwhile, in this process, the hook hook 83 guided through the inclined surface of the locking protrusion 65 is elastically deformed, and is hooked on the locking protrusion 65 so that the rear holder 80 is mounted to the lamp holder 50. . Accordingly, the rear holder 80 is fixed to the lamp holder 50 by the hook hook 83 is hooked to the locking projection 65, the coupling projection coupled to the coupling slit (73). By 93, the rear holder 80 is more firmly fixed to the lamp holder 50.
