However, the contact area between the spring sheets and the wires is small, resulting in a limited fixing effect. When pulled, the wires are easily separated. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 6 The utility model provides a technical solution: a PTV side-insertion spring terminal with firm wiring, comprising a shell 1, a conductive sheet 2 installed inside the shell 1, and two spring sheets 3 symmetrically arranged inside the shell 1, two inclined blocks 11 are arranged on the top of the two spring sheets 3, and the two inclined blocks 11 can play a dual fixing role, so that the wire is fixed more firmly, and after the wire is inserted, the inclined block 11 will press the wire against the inner wall of the fixing groove 13, which will make the wire bend and make it more difficult to pull out the wire. A fixing groove 13 matching with the inclined block 11 is arranged at the bottom of the conductive sheet 2, and one end of the inclined block 11 extends to the inside of the fixing groove 13. An unlocking block 9 is slidably installed inside the shell 1. Pressing the unlocking block 9 downward can make the spring sheet 3 bend, so that the inclined block 11 is away from the fixing groove 13, thereby releasing the fixation of the wire, and baffles 8 are arranged on both sides of the unlocking block 9. The baffle 8 is used to block the spring sheet 3 to prevent one end of the spring sheet 3 from deviating.

[0020] The spring sheet 3 is provided with a bending portion 10, and the baffle 8 is provided with convex edges 5 on both sides thereof to match the bending portion 10. The convex edges 5 are used to push the bending portion 10 to bend the spring sheet 3, thereby moving the inclined block 11 downward to release the fixation of the wire.

[0021] Among them, wiring holes 7 are opened on both sides of the shell 1, and a guide hole 6 is provided inside the shell 1. The guide hole 6 is used to guide the wire between the inclined block 11 and the conductive sheet 2 to facilitate fixing the wire. The guide hole 6 is connected to the wiring hole 7.

[0022] The spring sheet 3 is provided with a slot 12 , and the outer side of the conductive sheet 2 is provided with a block 14 matched with the slot 12 . The slot 12 and the block 14 cooperate to fix the relative position between the spring sheet 3 and the conductive sheet 2 .

[0023] A limiting column 4 is integrally formed inside the housing 1 , and the limiting column 4 is used to limit the spring sheet 3 to prevent the spring sheet 3 from deflecting.

[0024] When the lead is pulled out, the lead will drive the inclined block 11 to deform in the direction away from the spring sheet 3, thereby making the inclined block 11 more tightly against the lead, making it impossible for the lead to be pulled out. When the lead needs to be removed, the unlocking block 9 is pushed downward, and the unlocking block 9 drives the baffle 8 to move downward, and the baffle 8 drives the convex edge 5 to move downward, and the convex edge 5 bends the spring sheet 3 through the bending portion 10, and the spring sheet 3 drives the inclined block 11 to move, and the inclined block 11 no longer presses against the lead, and then the lead can be removed.
