Lamp mounting mechanism

Abstract

Abstract PURPOSE:To remove contact failure and miniaturize it reducing the cost by equipping a socket with a guide part which guides the lead wire of a lamp so that it may be connected to a printed wiring and equipping a hole in a board with a hooking means. CONSTITUTION:A lamp 1 is set in a socket 3 and two recesses 6 of the lamp 1 are held by the holding part 8 of the socket 3. Then the lead wire 5 of the lamp 1 is passed through a groove 9a formed in the guide part 9 of the socket 3 and hooked on the notch 7b of a base part 7. The socket which holds the lamp 1 is inserted in the mounting hole 11 provided in a case 2. The projections 10a of claws 10 are hooked on two erected parts 12 which are not attached with printed wiring 4 among four erected parts 12 provided at the inside periphery of the mounting hole 11, and the socket 3 is fixed to the case 2. On the other hand, when the socket is fixed to the case, the lead wire 5 contacts with the erected parts which are attached with the printed wiring 4, and electrical connection is performed between the lead wire and the wiring 4. In this way, the contact piece terminal of the socket is made needless.
