Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-7, in an embodiment of the present invention, a multi-terminal connecting terminal strip includes an insulating row seat 1, the top side of the row seat 1 is a stepped arrangement that gradually descends backwards, and an internal wiring screw hole 2 is formed on the top side of each step. The front side shaping of row seat 1 has the outside screw 3 of working a telephone switchboard with inside wiring screw 2 one-to-one, and the front side of row seat 1 is worn and is had the first guide way 4 with outside wiring screw 3 one-to-one, and first guide way 4 is located the top of the outside screw 3 of working a telephone switchboard that corresponds on row seat 1. The row seat 1 is provided with terminal pieces 5 which are in one-to-one correspondence with the first guide grooves 4, and the rear ends of the terminal pieces 5 pass through the first guide grooves 4 from the front side of the row seat 1 to the rear side and are positioned above the corresponding internal wiring screw holes 2. The front end of the terminal piece 5 is bent downwards to form a fixing piece 6, a first fixing hole 7 penetrates through the fixing piece 6, and a second fixing hole 8 corresponding to the internal wiring screw hole 2 is formed in the rear end of the terminal piece 5 in a molding mode. The bottom side of the row seat 1 is penetrated with second guide grooves 11 which are in one-to-one correspondence with the internal wiring screw holes 2, and the second guide grooves 11 are positioned behind the corresponding internal wiring screw holes 2 on the row seat 1. The row seat 1 is further provided with connecting pins 12 corresponding to the second guide grooves 11 one by one, and the top ends of the connecting pins 12 penetrate through the second guide grooves 11 from the bottom side of the row seat 1 upwards and are connected with the rear ends of the terminal pieces 5. After the second fixing holes 8 are aligned with the corresponding inner wiring screw holes 2, the first fixing holes 7 are aligned with the corresponding outer wiring screw holes 3. An internal fixing screw 9 and an external fixing screw 10 are also arranged; the internal fixing screw 9 is screwed with the internal wiring screw hole 2 and is used for fixing the fixing piece 6 at the front side of the row seat 1, and the external fixing screw 10 is screwed with the external wiring screw hole 3 and is used for fixing the rear end of the terminal piece 5 at the top side of the row seat 1. Preferably, the washer 15 is disposed on both the inner fixing screw 9 and the outer fixing screw 10.
When 3 wires are connected to needs, the 3 wires are connected to the fixing plate 6, the rear end of the terminal plate 5 and the bottom end of the connecting pin 12 respectively, the three wires are connected together to be conductive, one part only needs to be connected with one wire, the connection is more stable, the different side faces are located on the row seat 1, the wires connected to the fixing plate 6, the rear end of the terminal plate 5 and the bottom end of the connecting pin 12 are effectively guaranteed to be not prone to contact with each other, and the risk of short circuit is effectively reduced.
