In an embodiment of the present invention, the connecting terminal 2 can be assembled into an insulating base 3, the insulating base 3 is provided with at least two insertion holes 31, each connecting terminal 2 can be inserted into the insulating base 3 by matching with the insertion holes 31 to form a connector 1, wherein the connecting terminal 2 includes a butt-joint portion 21, a connecting portion 22 and a welding portion 23, the butt-joint portion 21 is located at one end (front end) of the connecting terminal 2, the welding portion 23 is located at the other end (rear end) of the connecting terminal 2, the butt-joint portion 21 and the welding portion 23 are respectively connected to two ends of the connecting portion 22, and the connecting portion 21 is located between the butt-joint portion 21 and the welding portion 23.

Referring to fig. 4 and 5 again, in the embodiment, the docking portion 21 can be electrically connected to an external terminal (not shown), the front side of the docking portion 21 can be provided with a socket 211, the connecting portion 22 is provided with an accommodating space 221 therein, and the accommodating space 221 and the socket 211 are communicated with each other, so that the external terminal can extend into the accommodating space 221 from the socket 211, the present invention is not limited to the state drawn in the drawings, and the skilled person can adjust the type of the docking portion 21 according to the product requirement, so as long as the docking portion 21 can be electrically connected to the external terminal, that is, the docking portion 21 of the present invention.

Referring to fig. 4 and 6, in the embodiment, the welding portion 23 is provided with a welding space 230, the welding space 230 is communicated with the accommodating space 221, an electronic wire 4 can extend from the welding portion 23 to be fixed on the connection terminal 2, wherein the electronic wire 4 is composed of an insulating layer 42 covering an electronic core wire 41, the welding portion 23 can be bent in a U shape, the insulating layer 42 can be stripped off to expose the electronic core wire 41 in a state that the electronic wire 4 is placed in the welding space 230, and molten tin is welded between the welding portion 23 and the electronic core wire 41, after the molten tin is cooled and solidified, the electronic core wire 41 and the welding portion 23 can be welded and fixed into a whole to form an electrical connection state, that is, the welding portion 23 fixes the electronic core wire 41 in a welding manner, and the U-bent shape of the welding portion 23 can increase the cohesion of the solder, thus, the connection strength between the soldering portion 23 and the electronic wire 4 can be greatly improved by soldering, and the problems of falling off, poor contact, poor conductivity and the like due to external force are not easy to occur, so that the length of the soldering portion 23 can be shortened, the connecting terminal 2 can reduce the overlapping part of the connecting terminal in the prior art, the overall length of the connecting terminal 2 can be greatly shortened, and meanwhile, the electronic wire 4 can also be firmly and electrically connected with the connecting terminal 2.

Referring to fig. 7, in order to prevent molten tin from flowing forward to the connecting portion 22 and even to the socket 211 in the state of welding molten tin between the welding portion 23 and the electronic core 41, the molten tin is cooled and solidified and remained in the connecting portion 22 and/or the butt-joint portion 21, which causes the space of the accommodating space 221 and/or the socket 211 to be reduced, so that the external terminal cannot be assembled with the connection terminal 2 smoothly, or, when the external terminal is assembled with the connection terminal 2, the insertion yield of the external terminal and the connection terminal 2 is affected, which causes problems such as poor signal contact or unstable power supply, and so on, an anti-solder-climbing structure can be provided in the connecting portion 22, for example, in this embodiment, the anti-solder-climbing structure can be a recess 222 located behind the connecting portion 22 (i.e., at the position where the connecting portion 22 is connected with the welding portion 23), in addition, the front side surface of the concave portion 222 can form a stopper portion 223, and the extending direction of the stopper portion 223 is toward the axis L of the connection terminal 2, so that the molten tin can be accumulated and condensed in the concave portion 222, and the molten tin cannot flow forward through the stopper portion 223 (i.e., toward the direction of the mating portion 21), but not limited thereto, in other embodiments, the concave portion 222 can be concave toward the bottom side of the connection terminal 2 without forming the stopper portion 223, or the tin climbing prevention structure can be provided with only the stopper portion 223, and the extending direction thereof is toward the axis L of the connection terminal 2, the extending direction of the axis L is the same as the inserting direction of the connection terminal 2 and the external terminal (i.e., the inserting direction of the connector 1 and another connector), therefore, taking fig. 7 as an example, the stopper portion 223 extends from the bottom side of the connection terminal 2 toward the top side, the tin solution can not flow forward (i.e. toward the direction of the butting portion 21), or the tin-climbing prevention structure can be a plating layer 224 (as shown by dotted lines in fig. 7) disposed on the inner surface of the connecting portion 22, and the material of the plating layer 224 can be nickel, so that the tin solution can not stay in the connecting portion 22.

Referring to fig. 2, 3 and 6 again, in this embodiment, each of the terminals 2 can be electrically connected to an external terminal in a state where the connector 1 is connected to another connector; when the connection state of the terminal 2 and the external terminal is to be released, the electronic wire 4 may be pulled by a force, in the case of frequent plugging and unplugging of the wiring, since the electronic wire 4 is welded integrally with the welding part 23 in a welding manner, therefore, the connection strength between the soldering portion 23 and the electronic wire 4 can be greatly enhanced, the connection terminal 2 and the electronic wire 4 can be prevented from being loosened due to being pulled by force, the service life of the connector 1 can be prolonged, and furthermore, since the welding portion 23 is welded integrally with the electron wire 4, not only can the terminal 2 omit the overlapping portion of the terminal provided in the prior art, meanwhile, the length of the welding part 23 can be shortened by the strong connecting ability of the welding, further, the overall length of the terminal 2 can be greatly reduced, and the length and volume of the connector 1 can be greatly reduced.

The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereto, and all the equivalent replacements that can be easily conceived by the technical personnel familiar with the present invention according to the technical content disclosed by the present invention should belong to the protection scope of the present invention.
