Description

Terminal for realizing electric connection and lamp Technical Field The utility model relates to the technical field of electronic connectors, in particular to a terminal for realizing electric connection and a lamp. Background In the prior art, one implementation manner of a terminal applied to a miniaturized lamp (such as a ceiling lamp) for realizing electrical connection is shown in fig. 1, and the electrical connection is realized by means of plug-in matching between a male end provided with a pin and at least one female end provided with a jack, specifically, a metal structure which is abutted with the pin along the width direction and has a width larger than that of the pin needs to be designed in the jack on the female end as shown in fig. 2. When the lamp is configured with various functions, such as dimming and toning functions, more electronic circuits need to be configured to realize illumination control, and a plurality of pins, such as four pins, may need to be configured. Since the conventional pins are provided in a discrete manner, possible implementation manners thereof are as shown in fig. 3 or fig. 4, and are implemented by using one terminal having four pins or two terminals having two pins. The above terminals have some technical problems: because the end part of the male end is smaller, the male end is not easy to grasp or clamp; because the contact pin is made of metal materials and is longer and thinner, the rigidity and the strength of the contact pin are difficult to ensure, and the problems of deformation, damage, poor electrical connection contact and the like are easy to occur in the plugging process; The design that contact pin set up separately, when needs a plurality of contact pins, the female end of terminal will occupy the great area of lamp plate, has not only influenced the space of arranging of devices such as lamp pearl and probably lead to the illuminating effect not good, has increased the design degree of difficulty moreover. Disclosure of utility model The utility model provides a terminal for realizing electric connection, which comprises a male end and at least one female end, wherein the male end comprises a columnar contact pin, at least two first electric connection parts which are insulated from each other are formed on the contact pin along the circumferential direction, an insertion hole for inserting the contact pin is formed in the female end, at least two second electric connection parts which are insulated from each other are formed on the inner wall of the insertion hole corresponding to the at least two first electric connection parts which are insulated from each other, and when the contact pin is inserted into the insertion hole, the first electric connection parts are electrically connected with the corresponding second electric connection parts. The male end of the terminal provided by the utility model is designed to be columnar, so that the problem of unstable electrical connection caused by easy deformation of the traditional contact pin during insertion due to insufficient strength and rigidity is avoided; in addition, when the terminal is applied to a small lamp, particularly a small lamp (such as a ceiling lamp) with color temperature switching and/or dimming functions, and is used for realizing electric connection, the larger the number of electric connection lines required by the same terminal (for example, the terminals of a standard functional ceiling lamp need to be electrically connected in two ways, and the ceiling lamp with color temperature switching and/or dimming functions needs to be electrically connected in three ways or four ways), the more obvious the limitation of the prior terminal including the background technology is, accordingly, the advantages of the terminal provided by the embodiment in terms of strength, rigidity and space saving are more obvious, and in some application scenes, the male end needs to be matched with a plurality of female ends to realize electric connection simultaneously, in this case, the poor contact between the terminal and the female end cannot be realized due to the fact that the strength and rigidity of the traditional pin are insufficient, and the poor contact between the female end and the terminal cannot be effectively realized. Optionally, the pin includes a columnar body made of an insulating material, and the at least two first electrical connection portions insulated from each other extend along an axial direction of the columnar body and are disposed at intervals. Optionally, the columnar main body is provided with at least two grooves arranged at intervals along the axial direction, and the at least two first electric connection parts insulated from each other are arranged in the corresponding grooves. The connection mode of the first electric connection part and the columnar main body can be pasting or electroplating, and considering the stability of the connection relation, as the
