Lamp socket and light appliance thereof
A lamp socket includes connection terminal bodies including connection terminals provided in sides of the lamp socket to contact with connection pins of the lamp, and connection terminal recesses into which the connection terminals are inserted, and connection caps to slide to press and fix the connection pins when the connection pins contact with the connection terminals.
1. A lamp socket provided in a housing of a light appliance to fix a lamp with connection pins, the lamp socket comprising:
connection terminals provided in one side of the socket to contact with the connection pins of the lamp;
a connection terminal body having connection terminal recesses into which the connection terminals are inserted;
connection caps for sliding to press and fix the connection pins so as to contact the connection pins with the connection terminals;
wherein the connection terminal body comprises guide recesses along which the connection caps slide, and the connection caps comprise guide protrusions inserted into the guide recesses; and
wherein the connection caps comprise connection protrusions protruded from inner sides of the connection caps such that the connection protrusions press the connection pins when the connection caps slide.
2. The lamp socket according to claim 1 , wherein an elastic member for increasing contacting force between the connection terminals and the connection pins is installed in the connection terminal recesses and the connection terminals are inserted into the upper sides of the elastic member.
3. The lamp socket according to claim 1 , further comprising supporting protrusions protruded from side of the connection terminal bodies to support the lamp when the connection pins contact with the connection terminals.
4. The lamp socket according to claim 1 , further comprising safety protrusions protruded from side of the connection caps to prevent an electric shock due to the connection pins when the connection pins of the lamp are coupled in the connection terminal recesses and safety engaging recesses formed in the central regions of the safety protrusions to allow the connection pins to penetrate therethrough.
5. The lamp socket according to claim 1 , wherein each of the connection terminal bodies further comprises:
an insertion unit to be inserted into the housing; and
a locking unit protruded over the insertion unit to be locked by the housing when the insertion unit is inserted into the housing;
wherein insides of the insertion unit and the locking unit are hollow such that electric wires for electrical connection of the connection terminals pass therethrough.
6. A light appliance to which a lamp is installed, comprising:
a housing as a case in which an electronic ballast and electronic components to drive the lamp are installed; and
the lamp socket according to claim 1 connected to the housing.
7. The light appliance according to claim 6 , wherein the pair of connection terminals of the lamp socket inwardly face each other or are outwardly spaced apart from each other corresponding to a direction where the lamp socket is coupled with the connection pins.
8. The light appliance according to claim 7 , wherein each of the connection terminal bodies further comprises:
an insertion unit to be inserted into the housing; and
a locking unit protruded over the insertion unit to be locked by the housing when the insertion unit is inserted into the housing;
wherein insides of the insertion unit and the locking unit are hollow such that electric wires for electrical connection of the connection terminals pass therethrough.
