[0021] To illustrate the ideas and objectives of this application, the following description will be provided in conjunction with the accompanying drawings and specific embodiments.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," "left," "right," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] like Figures 1 to 6 As shown, a connector terminal for preventing hot-plugging includes a positive terminal 10, a signal terminal 20, a negative terminal 30, and a connecting piece 40; one end of the positive terminal 10, the signal terminal 20, and the negative terminal 30 are respectively connected to one side edge of the connecting piece 40, and the lengths of the positive terminal 10 and the negative terminal 30 are equal and respectively greater than the length of the signal terminal 20.
[0025] like Figures 1 to 6As shown, the positive terminal 10 is connected with the positive pole 11 of the power line, the negative terminal 30 is connected with the negative pole 31 of the power line, and the signal terminal 20 is connected with the signal line 21 at one end close to the connecting piece 40. Then the connecting piece 40 is removed and put into a mold for injection molding to form the terminal 60. At this time, the length of the signal terminal 20 is shorter than that of the positive terminal 10 or the negative terminal 30. When the external device is plugged into the terminal 60, such as a lighting fixture, the external device first contacts the positive terminal 10 and the negative terminal 30 in the terminal 60. After the external device stably contacts the positive terminal 10 and the negative terminal 30 in the terminal 60, the external device contacts the signal terminal 20. This prevents the signal terminal 20, the positive terminal 10 and the negative terminal 30 from being simultaneously contacted by the external device, prevents the hot plug when the external device is plugged into the terminal 60, and prevents the generation of sparks, short circuit and fire phenomenon, and prevents the flash abnormality.

This can realize automatic pressing without manual operation, improve work efficiency and product quality.
[0030] Two pairs of pressing pieces 51 are arranged on both sides of each pressing groove 50. The positive pole 11 of the power line, the signal line 21 and the negative pole 31 of the power line are arranged in the corresponding pressing groove 50 in sequence, and the two pairs of pressing pieces 51 press the positive pole 11 of the power line, the signal line 21 and the negative pole 31 of the power line tightly, so that the positive pole 11 of the power line, the signal line 21 and the negative pole 31 of the power line are pressed more firmly in the pressing groove 50.
[0031] In some embodiments, as shown in Figures 1 to 6 The connecting piece 40 is provided with a plurality of positioning holes 41, and the positive pole connecting terminal 10, the signal connecting terminal 20 and the negative pole connecting terminal 30 are located on the same straight line with the corresponding positioning holes 41. The positioning holes 41 are arranged to facilitate the automatic equipment to find that the positive pole 11 of the power line corresponds to the positive pole connecting terminal 10, the signal line 21 corresponds to the signal connecting terminal 20, and the negative pole 31 of the power line corresponds to the negative pole connecting terminal 30, thereby improving the efficiency.
[0032] As shown in Figures 1 to 6 The positive pole connecting terminal 10, the signal connecting terminal 20 and the negative pole connecting terminal 30 are in the needle tube structure, which facilitates the injection molding of the positive pole 11 of the power line, the signal line 21 and the negative pole 31 of the power line and the corresponding positive pole connecting terminal 10, signal connecting terminal 20 and negative pole connecting terminal 30.
