Referring to fig. 10 and 11, specifically, the first card holder 120 includes a sinking platform 121 and a clamping leg 122, the sinking platform 121 is suitable for sleeving one end of the external terminal 200, and is provided with a second outlet bayonet suitable for a power cable to pass through, the clamping leg 122 is suitable for hooking the other end of the external terminal 200, a tip portion of the clamping leg 122 is provided with a guiding inclined surface 122a facing the external terminal 200, and the guiding inclined surface 122a is suitable for stripping the clamping leg 122 from the external terminal 200. In the utility model, when the outer terminal 200 is detached from the first clamping seat 120, the stripping of the clamping foot 122 is convenient, the power cable is clamped and seated on the second outlet bayonet, and the power cable is not easy to damage the detachment of the outer terminal 200.

Referring to fig. 10 and 11, specifically, the first card holder 120 includes a sinking platform 121 and a clamping leg 122, the sinking platform 121 is suitable for sleeving one end of the outer terminal 200, the clamping leg 122 is suitable for hooking the other end of the outer terminal 200, two sleeves 213 are convexly arranged at the other end of the outer terminal 200, the outer terminal 200 is arranged as a female end, the sleeves 213 are suitable for inserting the metal pins 420 of the inner terminal 400, and the clamping leg 122 is suitable for being arranged between the two sleeves 213, so that the buckle connection structure between the mounting seat 100 and the outer terminal 200 is in a foolproof structure. It will be appreciated that when the external terminal 200 is installed in the reverse direction (i.e., the two bushings 213 of the external terminal 200 are sunk into the sink 121), the external terminal 200 is too long to be outwardly deflected from the clamping legs 122, so that the external terminal 200 cannot be installed into the first clamping seat 120, i.e., the fool-proof structure.

Referring to fig. 11 to 13, the external terminal 200 includes a first insulation case 210 and an electrical connector, and the first insulation case 210 is integrally formed with a bushing 213.

Referring to fig. 9, specifically, the inner terminal 400 has a multi-stage stepped configuration, the lamp housing 310 is provided with a second socket adapted to be snap-connected to the inner terminal 400, and the second socket has a multi-stage stepped configuration, so that the snap-connection structure between the lamp housing 310 and the inner terminal 400 is a foolproof structure.
