Embodiment Construction

[0018] The lamp of the preferred embodiment of the present invention comprises a housing 1 forming a main body and a circuit board 3, a battery 2, a connecting circuit and a light bulb installed in the housing 1, the connecting circuit electrically connects the circuit board 3 and the light bulb, and the battery 2 and the circuit board The contact electrode 4 on the 3 contacts and energizes, and provides power for the bulb through the connection circuit.

[0019] Wherein, the casing 1 is provided with a cavity for accommodating the battery 2 . The direction of the line connecting the centers of the positive and negative electrodes of the installed battery 2 is the axial direction of the cavity. At both ends of the cavity along the axial direction, one end is equipped with an elastic contact terminal, which is in contact with the negative terminal surface of the battery 2 for electricity, and the other end is equipped with a circuit board 3. In body 1. The circuit board 3 is ...

Abstract

The invention relates to a lamp. The lamp comprises a shell, a battery and a circuit board, wherein the shell is provided with a cavity for accommodating the battery; the circuit board is positioned on one side in the cavity close to a positive cap of the battery and provided with a salient contact electrode; the contact electrode is correspondingly and electrically connected with the positive cap; and a buffer element which allows axial displacement of the contact electrode along the battery is arranged between the contact electrode and the circuit board. By using the lamp, buffer is provided for the impacted contact electrode by increasing the buffer element between the contact electrode and the circuit board, so direct related collision of the circuit board can be prevented so as not to loosen or even drop electronic elements on the circuit board, and the impact resistance of the entire lamp is enhanced.

Description

technical field [0001] The present invention relates to a lamp, and more particularly relates to a lamp using a battery as a power source. Background technique [0002] Dry battery is a common battery, its positive and negative poles are respectively located on the two end faces of its cylindrical body, and the positive end face is equipped with a raised positive cap with a certain height. Dry batteries are often used to provide power for many daily small appliances, such as remote controls, flashlights and other portable lamps, electric toys, etc. Such as figure 1 As shown, in a lamp, the conventional structure for installing a dry battery is: a cavity for accommodating the battery 20 is provided in the lamp housing 10, and an elastic contact terminal such as a spring or shrapnel is installed at one end of the cavity for connecting to the negative pole of the battery 20. The other end of the chamber is equipped with a circuit board 30 , on which a protruding contact elect...
