The lantern plug 1000 includes a fixing member 1100, a deformation body 1200, a connection body 1300 and a wire, wherein a through hole 1300 is arranged in the connection body 1300 to accommodate the wire and the fixing member 1100. One end of the fixing member 1100 is fixed in the through hole 1300 and connected to the wire in a connection manner of adjustable insertion depth including a snap connection, a pin connection, a screw connection, etc. The other end of the fixture 1100 is connected to the deformation body 1200 to form an energizing line of the deformation body 1200-the fixture 1100-the wire. The deformation body 1200 is disposed between the other end of the fixing member 1100 and the connection body 1300, and is disposed around the fixing member 1100, i.e., one end of the fixing member 1100 is inserted into the through hole 1300 of the connection body 1300 through the deformation body 1200, and the other end of the fixing member 1100 and the connection body 1300 are pressed against the deformation body 1200. Since the fixing member 1100 is fixed in the through hole 1300 in a connection manner with adjustable insertion depth, when the fixing member 1100 is inserted deeper, the compression of the fixing member 1100 and the wiring body 1300 to the deformation body 1200 is more obvious, the elastic force generated by the compression of the deformation body 1200 is greater, that is, the outward expansion force of the lantern plug 1000 is greater, and the connection with the female head is more tight. Further, the function of generating elasticity through the deformation of the deformation body 1200 assisted by the fixing piece 1100 is realized, the dependence on the elasticity of the deformation body 1200 is reduced, and after the elasticity of the deformation body 1200 is reduced due to long-term use, part of the elasticity of the deformation body 1200 can still be restored through the extrusion of the fixing piece 1100 and the wiring body 1300, so that the service life of the lantern plug 1000 is prolonged.

In this embodiment, an external thread is disposed at one end of the fixing element 1100, an internal thread is correspondingly disposed in the through hole 1300, and the connection mode with adjustable insertion depth is threaded connection, so that the fixing element 1100 is convenient to be inserted and removed, the insertion depth is adjusted steplessly, and the deformation body 1200 is better assisted to generate elastic force. In some embodiments, the fixing member 1100 has a tooth at one end, and the through hole 1300 has a stepped slot with a spline connection. In other embodiments, one end of the fixing member 1100 is provided with a plurality of bolt holes, the inner wall of the through hole 1300 is provided with a coupling hole to the outside, and the bolts sequentially pass through the coupling hole of the through hole 1300 and any bolt hole of the fixing member 1100 to fix the fixing member 1100 to the wiring body 1300.

The insertion end 1120 is provided with connection features such as protrusions, through holes 1300, threads, etc., and the through holes 1300 are correspondingly provided with connection features such as tooth grooves, through holes 1300, threads, etc., and the insertion end 1120 penetrates through the deformation body 1200 to be fixed in the through holes 1300, so that the fixing piece 1100 is fixed on the wiring body 1300 in a connection mode with adjustable insertion depth. The fixing end 1110 is provided with a protrusion, a groove, a buckle and other blocking features to limit the deformation body 1200 to be arranged between the fixing end 1110 and the wiring body 1300, so that the fixing end 1110 and the wiring body 1300 together generate a relative extrusion effect on the deformation body 1200.

In this embodiment, the cross-sectional area of the fixed end 1110 is larger than the cross-sectional area of the insertion end 1120, i.e., the fixed end 1110 itself has a blocking effect with respect to the insertion end 1120. When the insertion end 1120 is fixed to the through-hole 1300 through the variation body 1200, the fixed end 1110 itself abuts against the variation body 1200, thereby pressing the variation body 1200 between the fixed end 1110 and the wiring body 1300.

The end face of the fixed end 1110 far from the insertion end 1120 is provided with a cross or a straight groove, which is convenient for inserting a cross or a straight tool piece for fixing operation.

The first clamping ring 1210 is sleeved on the insertion end 1120, and can slide freely between the fixed end 1110 and the connector 1300, and the elastic strip 1220 stretches or bends along with the sliding of the first clamping ring 1210, so as to generate elastic forces with different magnitudes. When the depth of the fixing piece 1100 inserted into the wiring body 1300 is deeper, the distance between the fixing end 1110 and the wiring body 1300 is shorter, the first clamping ring 1210 is closer to the fixing end 1110, the elastic strip 1220 is extruded by the fixing end 1110 and the first clamping ring 1210 to expand outwards, and the elastic force generated by the deformation body 1200 is larger, so that the function of assisting the deformation body 1200 in deformation of the fixing piece 1100 to generate elastic force is realized, the dependence on the elasticity of the elastic strip 1220 is reduced, and the service life of the lantern plug 1000 is prolonged. In some embodiments, both ends of each spring strip 1220 are fixed to the fixed end 1110 and the first clamping ring 1210 by welding, or bonding, or the like. In other embodiments, the spring 1220 and the fixed end 1110, or the spring 1220 and the first clamping ring 1210, or the spring 1220 and the fixed end 1110 and the first clamping ring 1210 are integrally formed.

The first clamping ring 1210 and the second clamping ring 1230 are both sleeved on the insertion end 1120 and freely slide between the fixed end 1110 and the wiring body 1300, so that the deformation body 1200 is arranged between the fixed end 1110 and the wiring body 1300, when the depth of the fixing piece 1100 inserted into the wiring body 1300 is deeper, the distance between the fixed end 1110 and the wiring body 1300 is shorter, the distance between the first clamping ring 1210 and the second clamping ring 1230 is shortened, the elastic strip 1220 is extruded by the first clamping ring 1210 and the second clamping ring 1230 to expand outwards, and larger elasticity is generated, the function of assisting the deformation of the deformation body 1200 by the fixing piece 1100 to generate elasticity is realized, the dependence on the elasticity of the elastic strip 1220 is reduced, and the service life of the lantern plug 1000 is prolonged. Since the deformation body 1200 is sleeved on the fixing piece 1100 through the clamping ring, when the deformation body 1200 fails completely, the lantern plug 1000 can be maintained by independently replacing the deformation body 1200, and the maintenance cost is greatly reduced.

Because the fixing end 1110 needs to contact with the female head (during fixing), the fixing end 1110 in this embodiment is hemispherical in shape, so as to avoid damage to the female head due to the edges and corners. The insert end 1120 and the limit end 1130 are shaped as cylinders to enable sliding to be smoother during the fixing operation, and the insert hole 1311 and the limit hole 1312 are shaped as circular holes.
