Description

Lamp module
Technical Field
The invention relates to the field of electrical connection, and belongs to a lamp module.
Background
The switch wiring device is a power switch assembly with a connecting circuit or a line, is arranged on an operation panel or a distribution box of electronic and motor equipment and is used for connecting a wiring circuit. It is known that a switch wiring device uses a conductive element, a wiring circuit or a lead wire of an electronic or motor device, which is covered in an insulating housing (usually made of plastic material), and a screw lock to control the conduction or disconnection of the conductive element and the wiring circuit or the lead wire in cooperation with the operation of a switch button, so as to establish the power supply function of an on/off circuit; for example, patent application No. 201310294137.8 entitled switch improvement structure provides an exemplary embodiment.
One problem with such switch wiring devices in terms of operational use and structural design is that the insulating housing is provided with a wire insertion hole and a locking hole for the operating screw which are in communication with each other, and personnel operating tools are provided to control the screw to lock the wire entering from the wire insertion hole. In practice, the screw must be in a release state so as to insert the wire into the wire insertion hole; when the screw is in the released state, the screw may be deflected, which often makes the operation of the screw to align the locking wire and the electrical contact (or electrical contact) troublesome and difficult.
In order to improve the above problems, the prior art also discloses a structure in which a guiding slot, a guiding bar and a spring are arranged on the insulating housing and the contact. But the structure is not only more complex, increasing the manufacturing cost; also, the housing volume must generally be increased to avoid interference between the guide structure and the conductive element. Furthermore, increasing the volume of the housing is not conducive to the evolution and design trend of miniaturization of the switch terminal block device.
In some use environments (for example, the operation of machine equipment can generate vibration), the screw is easy to loosen in the process of long-term use, so that the wire is easy to loosen. Particularly, the screw mechanism and the wire or wire rod can be locked and loosened only by using tools during the pivoting operation, which is relatively troublesome; which is not desirable.
The prior art also discloses a structure that uses a metal spring sheet with an alpha-shaped profile to press a wire or a wire in cooperation with the internal structure design of the housing, instead of locking the wire by a screw mechanism. However, as known to those skilled in the art, in addition to the bending of the α -type metal leaf into a special shape, the metal leaf must be provided with a mouth, and the other end of the metal leaf is passed through the mouth, so that a swinging structure is formed on the mouth to press the wires. Therefore, the structure of the alpha-type metal elastic sheet is relatively troublesome and complicated to manufacture; which is not desirable.
Representatively, these reference data show the skill in the art in relation to the switch wiring device and the associated combination design; if the structural combination of the insulating shell and the conductive element, the electric connector and the switch is redesigned and considered, the structure is different from that of a conventional user, the use form of the insulating shell can be changed, and the insulating shell is different from that of the conventional method; substantially, it will also increase its application range. For example, under the condition of not increasing the volume of the switch wiring device, the structures of the switch wiring device are easy to manufacture and operate, the operation trouble and difficulty of aligning and locking a conducting wire and a power connection head by commonly known operation screws are improved, and the situations of complex structures such as an insulating shell combination guide groove, a conducting bar, a spring, application of an alpha-shaped metal elastic sheet and the like are improved.
In the prior art, lamp modules with different specifications need to be selected according to different voltages, and a plurality of different circuit modules need to be arranged.
In the prior art, due to the limitation of the product structure and the use environment, if the use requirement of the product is met, the quick connection and disconnection of the connection line can be realized without increasing the product volume, which is an urgent problem to be solved.
