Background
In the conventional method, when connecting the wires, the insulating tape is used to wind the conductive core of the two wires exposed outside the insulating sheath, so as to connect the two wires, thereby achieving the electrical conduction effect. However, the use of tape is prone to lead environmental influences, resulting in electrical leakage or moisture failures, and thus, a lead connecting device 1 is proposed in the prior art, as shown in fig. 1A, of U.S. patent No. 4883925. The method comprises the steps of utilizing an insulating tube 11 with an inner layer coated with an adhesive material 111, placing a welding sleeve 112 with smooth inner and outer surfaces into the insulating tube, mutually adhering and fixing the outer surface of the welding sleeve 112 and the inner surface of the insulating tube 11 through the adhesive material 111, utilizing an external heat source to firstly melt the welding sleeve 112 to pass through so as to connect conductive cores of two leads, and then heating and shrinking the insulating tube 11 to fix the leads so as to achieve the effects of connecting the leads and conducting the leads electrically. However, the cost of applying the adhesive material 111 to the inner layer of the insulating tube 11 of the connecting device 1 is high, and the manufacturing process of applying the adhesive material 111 and then placing the welding sleeve 112 is not easy.
Referring to fig. 1B, prior art U.S. patent No. 5137478 proposes an easy-insertion terminal connector having a fusion-splicing material. The conductive terminal has a semicircular tail portion 12, and a welding material 121 is coated in the semicircular tail portion 12 to be connected with the conductive core.
