[0002] The spring terminal is an electronic and electrical connector that is easy to industrialize and has reliable electrical contact performance. It is mainly composed of a male plug and a spring seat and is widely used in lighting appliances, household appliances, electronic instruments and other products. At present, the back structure of the spring terminal on the market is generally set as two windows, and the locking convex point is set on the middle horizontal bar of the two windows, which does not have elastic fit. When the male plug and the spring terminal are plugged together for assembly, the insertion resistance is large, which affects the assembly efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a spring terminal which is simple in structure, convenient and quick to assemble, can effectively improve the assembly efficiency, has high connection reliability and is easy to insert.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] As a further improvement of the above technical solution:

[0007] A boss portion is formed in the middle of the plug-in bottom wall, and the latch tongue is arranged on the boss portion.

[0008] The clamping tongue is an isosceles trapezoidal structure, and the width of the clamping tongue gradually decreases from an end close to the inserting portion to an end close to the riveting portion.

[0009] The riveted portion comprises a rivet wire core foot and a rivet wire leather foot. The rivet wire core foot is provided with a rivet wire anti-slip line, and the extension direction of the rivet wire anti-slip line is perpendicular to the axial direction of the rivet wire core foot.

[0010] The main body of the spring seat is a straight spring terminal, the rivet wire core pin and the rivet wire leather pin are both U-shaped structures, and the axial direction of the rivet wire core pin and the rivet wire leather pin is parallel to the plug-in movement direction of the plug-in part.

[0011] The main body of the spring seat is a flag-shaped spring terminal, the rivet wire core pin and the rivet wire leather pin are both L-shaped structures, and the axial direction of the rivet wire core pin and the rivet wire leather pin is perpendicular to the plug-in movement direction of the plug-in part.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The plug-in spring terminal of the utility model is easy to insert and is formed with an N-shaped clamping tongue on the plug-in bottom wall by punching. When the plug-in part and the male plug-in piece are inserted, the three sides cut and separated on the clamping tongue will be squeezed by the male plug-in piece and elastically deformed, thereby achieving the effect of easy insertion and installation. The utility model has a simple structure and is convenient and quick to assemble, and can effectively improve the efficiency of assembly operation. When the tension hole on the plug-in piece is aligned with the locking buckle convex point on the clamping tongue, the clamping tongue will automatically rebound under the action of the elastic restoring force, so that the tension hole and the locking buckle convex point are buckled, thereby meeting the pull-out force requirement between the male plug-in piece and the plug-in spring terminal, and the connection reliability is high.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6As shown, the plug-in spring terminal of this embodiment, which is easy to plug in, includes a plug-in spring seat body 1, one end of the plug-in spring seat body 1 is provided with a rivet portion 2, the other end of the plug-in spring seat body 1 is provided with a plug-in portion 3, the plug-in portion 3 includes a plug-in bottom wall 301, both sides of the plug-in bottom wall 301 are bent to form plug-in tubes 302, the plug-in bottom wall 301 is punched with an N-shaped tongue 304, the end of the tongue 304 close to the plug-in portion 3 is connected to the plug-in bottom wall 301, and the end of the tongue 304 close to the rivet portion 2 is provided with a locking protrusion 305. The spring terminal which is easy to plug in is formed with an N-shaped tongue 304 by punching out on the plug-in bottom wall 301. When the plug-in part 3 is plugged in with the male plug-in piece, the three cut sides of the tongue 304 will be squeezed by the male plug-in piece and elastically deformed, thereby achieving the effect of easy plug-in. The structure is simple, and the assembly is convenient and quick, which can effectively improve the assembly efficiency. When the tension hole on the male plug-in piece is aligned with the locking protrusion 305 on the tongue 304, the tongue 304 will automatically rebound under the action of the elastic restoring force, so that the tension hole and the locking protrusion 305 are buckled, thereby meeting the pull-out force requirement between the male plug-in piece and the spring terminal, and the connection reliability is high.

[0024] Preferably, a boss portion 303 is formed in the middle of the plug bottom wall 301, and a latch tongue 304 is disposed on the boss portion 303. In this embodiment, when the plug part 3 is plugged into the male plug piece, the boss portion 303 will abut against the bottom surface of the male plug piece, thereby pressing the top surface of the male plug piece against the plug tube 302, preventing the male plug piece from swinging up and down, effectively improving the connection stability between the male plug piece and the plug part 3, and improving the conductivity between the male plug piece and the plug spring terminal.

[0025] Preferably, the tongue 304 is an isosceles trapezoidal structure, and the width of the tongue 304 gradually decreases from the end close to the plug-in portion 3 to the end close to the riveted portion 2. In this embodiment, the tongue 304 is set to an isosceles trapezoidal structure, and the width of the tongue 304 near the plug-in portion 3 is larger, which can effectively enhance the structural strength of the root of the tongue 304 and prevent fracture failure. The width of the tongue 304 near the riveted portion 2 is smaller, so the stress required for the elastic deformation of the end of the tongue 304 is smaller, the elastic limit is larger, and it is easier to insert.

[0026] Preferably, the riveting part 2 includes a rivet wire core pin 201 and a rivet wire leather pin 202, and a rivet wire anti-slip wire 203 is provided on the rivet wire core pin 201, and the extension direction of the rivet wire anti-slip wire 203 is perpendicular to the axial direction of the rivet wire core pin 201. In this embodiment, when connecting the wire, the wire passes through the rivet wire leather pin 202 and the rivet wire core pin 201 in sequence, and then the rivet wire leather pin 202 and the rivet wire core pin 201 are riveted and pressed, so that the rivet wire leather pin 202 presses the insulating skin layer of the wire, and the rivet wire core pin 201 presses the wire core, thereby improving the connection stability between the spring seat body 1 and the wire, which is conducive to extending the service life.

[0028] like Figures 1 to 3 As shown, in this embodiment, the spring seat body 1 is a straight spring terminal, the rivet wire core pin 201 and the rivet wire leather pin 202 are both U-shaped structures, and the axial direction of the rivet wire core pin 201 and the rivet wire leather pin 202 is parallel to the plug-in movement direction of the plug-in part 3.

[0029] Embodiment 2

[0030] Figures 4 to 6 As shown, in this embodiment, the spring seat body 1 is a flag-shaped spring terminal, the rivet wire core pin 201 and the rivet wire leather pin 202 are both L-shaped structures, and the axial direction of the rivet wire core pin 201 and the rivet wire leather pin 202 is perpendicular to the plug-in movement direction of the plug-in part 3.
