A connection terminal for electrically connecting at least two conducting wires, the connection terminal comprising a housing provided with a mounting cavity, a contact assembly arranged in the mounting cavity, and a support member detachably arranged in the mounting cavity and provided with insertion holes;
- the contact assembly comprises a conductive clip and a bus bar, the conductive clip is provided with at least two wire passages and elastic tongues corresponding to the at least two wire passages, and the bus bar is inserted into the at least two wire passages and supported in the housing;
- the conductive clip is arranged in the mounting cavity with an opening facing the support member and is assembled to the mounting cavity via the support member;
- the conducting wires with insulation sheath peeled off can pass through the insertion holes in such a way that the conducting wires are located between the conductive clips and the bus bar and be inserted into the at least two wire passages, so that the elastic tongues are pressed upon the conducting wire;
- wherein the conductive clips are integrally formed, and each has a supporting section, a tongue forming section, an approximately C-shaped cavity section and an extension section that are connected in sequence;
- wherein the supporting section abuts against the support member, and the supporting section and the tongue forming section are connected by a pre-deformed first elastic arch;
- the elastic tongues spaced apart each is formed by punching of the tongue forming section, the tongue forming section is connected to one end of the approximately C-shaped cavity section through a pre-deformed second elastic arch, the other end of the approximately C-shaped cavity section extends horizontally with an extension section, and the at least two wire passages communicate with an interior of the approximately C-shaped cavity section;
- wherein two ends of the tongue-forming section are respectively connected to the supporting section and the approximately C-shaped cavity section through the pre-deformed first elastic arch and the pre-deformed second elastic arch respectively, so that a clamping space can be formed between the conductive clip and the bus bar, and the conducting wires with insulating sheath peeled off can be elastically pressed in the clamping space;
- wherein the bus bar is formed by bending through a conductive sheet structure, the bus bar has a plurality of heads that cooperates with the at least two wire passages and extends outside the passage and a plurality of bent portions disposed on a side away from the plurality of heads;
- the bent portion is supported and disposed in the housing, and is assembled into the mounting cavity via the support member to abut and drive the bent portion to fix the bus bar horizontally in the conductive clip in a direction in which the conducting wire is inserted, so that the conductive clip and the bus bar form a clamping space for elastically crimping the conducting wire;
- the bent portion is bent vertically relative to the bus bar, so that the cross section of the bus bar where the bent portion is located has an L shape;
- the head and the bent portion are at both ends of the L shape;
- the bus bar is horizontally laid in the conductive clip so that the bent portion is supported vertically in the housing and is sandwiched between the support member and the conductive clip;
- the support member has a mating surface which is in contact with the bent portion;
- by the support member fitting into the mounting cavity, one side surface of the bent portion supported in the housing abuts against the mating surface with each other by surface contact, and the other side surface of the bent portion abuts against the lower end of the conductive clip.
