Multi-functional flashing light capable of improving stability

Abstract

The invention relates to a multi-functional flashing light capable of improving stability. An under-current relay is provided with a normally open contact, one end of the normally open contact is connected with the anode wire of a signal light arranged on the outer wall of a cylinder bar, the other end of the normally open contact is connected with the anode of a battery of the signal light arranged on the outer wall of the cylinder bar, the cathode of the battery of the signal light is connected with the cathode wire of the signal light, the bottom of the middle portion bar body is connected with the rear end of the lower portion bar body extending from back to front, in addition, the upper portion bar body is located in a female contact, the outer surface of the middle portion bar body makes contact with the inner surface of a second hole used for pouring an adhesion agent, and the lower portion bar body is in interference fit with a first hole used for stabilizing a male contact. The structure avoids the defects that a combination contact in the prior art has an unstable sheet-shaped protrusion of the male contact, and the current of an illuminating light can not be judged whether the work is normal or not from the appearance.

Description

technical field [0001] The invention belongs to the technical field of strobe lamps, and in particular relates to a multifunctional strobe lamp with improved stability. Background technique [0002] Strobe lights use electronic means to make the light source flicker slowly or quickly, which plays a warning role. The light source of the strobe light is LED light-emitting diode: the salient feature of this light source is high efficiency, power saving, and excellent brightness can be obtained with a well-designed lens, which has become a new trend in the field of strobe lights; but the strobe lights LED light-emitting diodes only act as flickering according to the frequency, and cannot achieve continuous lighting. However, the current lighting LED light-emitting diodes are combined with their LED light-emitting diode batteries through a joint head. The joint head includes a male head and a female head, and The bonding head is welded on the circuit board, that is, the sheet-sh...

The light source of the strobe light is LED light-emitting diode: the salient feature of this light source is high efficiency, power saving, and excellent brightness can be obtained with a well-designed lens, which has become a new trend in the field of strobe lights; but the strobe lights LED light-emitting diodes only act as flickering according to the frequency, and cannot achieve continuous lighting. However, the current lighting LED light-emitting diodes are combined with their LED light-emitting diode batteries through a joint head. The joint head includes a male head and a female head, and The bonding head is welded on the circuit board, that is, the tab-shaped protrusion of the male head of the bonding head is extended into the circuit board, and then the welding is performed with a welding material

[0003] The currently used combination head including male head and female head usually connects the male head to the lower end of the female head. The male head has a sheet-shaped protrusion. At the same time, the flaky protrusions of the male head are combined with the holes of the female head, and when the flaky protrusions of the male head are not accurately connected with the holes of the female head, the flaky protrusions that hit the male head often occur. Raised surface, in addition, the flaky protrusions of the male head are generally columnar structures, which only rely on welding materials to connect with the circuit board. If the impact force of the flaky protrusions of the male head is too large, it is easy to make the flaky protrusions of the male head If the circuit board is separated, it will also pass through the lower end of the female head, which will damage the joint head, and if the flaky protrusions of the male head are combined with the holes of the female head many times, this will often make the female head Shaking occurs, because there is no deflection correction for the flaky protrusions of the male head, the impact on the flaky protrusions of the male head is often not small, and the flaky protrusions of the male head will be separated from the circuit board. As mentioned above, the existing bonding head has the defect that the sheet-shaped protrusion of the male head is unstable; in addition, the introduction of the bonding head leads to the complexity of the lighting circuit, and makes it impossible to judge whether the current of the lighting lamp is working normally from the appearance
