DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a direct plug-in terminal, including a housing 1, a positioning block 5 integrally formed with the housing 1, a spring piece 2 disposed outside the positioning block 5, and a conductive piece 3 disposed inside the housing 1. The housing 1 is integrally formed with a first positioning strip 6 and a second positioning strip 7. A retaining piece 4 for shielding the spring piece 2 is installed between the first positioning strip 6 and the second positioning strip 7. The retaining piece 4 is used to shield the spring piece 2 to prevent the spring piece 2 from warping, ensuring that the spring piece 2 can play a good fixing role on the wire, making the wire firmly fixed. The two sides of the retaining piece 4 are respectively provided with a first pin 11 and a second pin 15. The inner side wall of the second pin 15 is provided with an inclined block 16. The inclined block 16 cooperates with the second groove 20 to connect and fix the second pin 15 with the conductive piece 3. The card slot 12 cooperates with the card block 9 to connect and fix the first pin 11 with the first positioning strip 6, thereby fixing the retaining piece 4 to prevent the retaining piece 4 from warping under the action of the spring piece 2. The conductive piece 3 is provided with a second groove 20 that cooperates with the inclined block 16. The side of the second positioning strip 7 close to the positioning block 5 is provided with a card block 9. The first pin 11 is provided with a card slot 12 that cooperates with the card block 9. The bottom of the first pin 11 is provided with an opening 13, and the opening 13 communicates with the card slot 12. The opening 13 facilitates the card block 9 to be inserted into the card slot 12.

[0021] Wherein, a slot 8 is provided on one side of the second positioning strip 7. The slot 8 is used to cooperate with the second pin 15 to limit the retaining piece 4 and prevent it from moving.

[0022] Wherein, fixing blocks 17 are provided on both sides of the second pin 15. The fixing blocks 17 abut against the inner wall of the slot 8. The fixing blocks 17 play a limiting role on the second pin 15, making the installation of the retaining piece 4 more stable.

[0023] Wherein, a convex block 14 is provided on the side of the first pin 11 close to the conductive piece 3. A first groove 10 that cooperates with the convex block 14 is provided inside the conductive piece 3. The cooperation between the first groove 10 and the convex block 14 can also play a fixing role on the retaining piece 4, making the installation of the retaining piece 4 more firm.

[0024] Wherein, a retaining block 19 is provided on the top of the conductive piece 3. The retaining block 19 is used to limit one side of the retaining piece 4 to ensure that the retaining piece 4 is firmly installed and does not shake.

[0025] Wherein, a convex edge 18 is provided on one side of the conductive piece 3. The convex edge 18 is used to limit one end of the spring piece 2 to make its installation stable.

[0026] Wherein, the cross-section of the opening 13 is trapezoidal. The trapezoid can more easily guide the card block 9 into the card slot 12, and it is not easy for the card block 9 to separate from the card slot 12 after being inserted.

[0027] Specifically, when installing the retaining piece 4, only need to align the second pin 15 with the slot 8, align the first pin 11 between the first positioning strip 6 and the positioning block 5, insert the retaining piece 4, press the retaining piece 4, the clamping block 9 is guided by the opening 13 and snapped into the card slot 12, the inclined block 16 is snapped into the second groove 20, the convex block 14 is snapped into the first groove 10, and the fixing block 17 abuts against the inner wall of the slot 8, so as to realize the installation and fixation of the retaining piece 4. After the retaining piece 4 is installed, it will block the spring piece 2 from tilting, thus ensuring that the wire is firmly fixed.
