An insertion hole 221 communicating with the first housing cavity 23 is concavely provided in the top surface 220 of the cylindrical portion 22, and the elastic terminal 3 includes a substantially rectangular substrate portion 31 mounted in the first housing cavity 23, an elastic contact arm 32 formed by extending forward and upward from the front end of the substrate portion 31 in an inclined manner and exposed to the insertion hole 221, a pair of protruding pieces 33 formed by extending forward from the front end of the substrate portion 31, and a soldering portion 34 extending from the rear end of the substrate portion 31 to the main body portion 21. The pair of protruding pieces 33 are located on both lateral sides of the elastic contact arm 32 in a lateral direction perpendicular to the front-rear direction and are spaced apart from the elastic contact portion 32.
Specifically, the first receiving cavity 23 includes a first receiving groove 231 and a pair of second receiving grooves 232 located at both lateral sides of the first receiving groove 231 and communicating with the first receiving groove 231, the second receiving grooves 232 are disposed below the first receiving groove 231, and the second receiving grooves 232 are close to the bottom of the main body 21 in the vertical direction. The elastic contact arm 32 is accommodated in the first accommodation groove 231, and the pair of protruding pieces 33 are accommodated in the pair of second accommodation grooves 232, respectively. In the present invention, the pair of protruding pieces 33 are relatively narrow, in order to prevent the narrow protruding pieces 33 from piercing the bottom of the main body 21 during the process of loading the elastic terminal 3 into the first receiving cavity 23 and causing damage to the internal insulating member 2, the pair of protruding pieces 33 extend laterally inward in the lateral direction to form widened pieces 35 received in the second receiving grooves 232, and the widened pieces 35 expand the lateral dimension of the protruding pieces 33 so as to prevent the protruding pieces 33 from piercing the bottom of the main body 21 downward.
In the present invention, the elastic contact arm 32 has a starting end 30 connected to the base plate portion 31, and the transverse width of the elastic contact arm 32 is gradually reduced from the starting end 30 to the front, so that the elastic contact arm 32 has reliable connection strength.

The first section 321 is in a substantially trapezoidal structure, the second section 322 is in a substantially rectangular structure, the transverse width of the second section 322 is not greater than that of the first section 321, and the side edges of the first section 321 and the second section 322 are in smooth transition. A through groove 3212 is formed in the middle of the first segment 321, and the elastic contact arm 32 has better elastic performance by forming the through groove 3212 at a position close to the starting end 30 of the elastic contact arm 32.
A pair of lateral side portions 311 of the substrate portion 31 are respectively received in the pair of second receiving grooves 232, a convex portion 312 protruding upward from an upper surface of the side portion 311 is punched on a lower surface of the side portion 311, the convex portion 312 is substantially elongated in a front-rear direction, a front end of the convex portion 312 forms a guiding protrusion 3121, when the elastic terminal 3 is assembled, the guiding protrusion 3121 is used for guiding into the second receiving groove 232, and the convex portion 312 is finally locked in the second receiving groove 232 in an up-down direction.

Specifically, the second receiving cavity 24 includes a third receiving groove 241 and a pair of fourth receiving grooves 242 located at both lateral sides of the third receiving groove 241 and communicating with the third receiving groove 241, and the pair of fourth receiving grooves 242 is located above the third receiving groove 241. The plate-shaped base 41 is inserted into and fixed in the fourth receiving slot 242, a protruding point 411 is punched on a lower surface of an upper surface of a free end of the plate-shaped base 41, and the contact portion 3211 of the elastic contact arm 32 is in contact with the protruding point 411 in a normal state. A pair of arc-shaped protrusions 412 is punched on the upper surfaces of the lower surfaces of the two lateral sides of the plate-shaped substrate 41, the pair of protrusions 412 are located on the two sides of the protruding point portion 411 in the lateral direction, the protrusions 412 are staggered with the protruding point portion 411 in the front-rear direction, and the pair of protrusions 412 are respectively clamped in the pair of fourth receiving grooves 242 in the up-down direction.

The soldering portion 34 of the elastic terminal 3 is a plate-shaped body formed by folding back downward from the base plate portion 31, a first vertical portion 36 is connected between the soldering portion 34 and the base plate portion 31, the leg portion 42 of the fixed terminal 4 is a plate-shaped body formed by folding back downward from the plate-shaped base 41, a second vertical portion 43 is connected between the leg portion 42 and the plate-shaped base 41, and the soldering portion 34 and the leg portion 42 extend in opposite directions. After the elastic terminal 3 is inserted into the first receiving cavity 23, the first vertical portion 36 is limited on the first end surface 211 and the welding portion 34 is located at the bottom of the main body 21. After the fixed terminal 4 is inserted into the second receiving cavity 24, the second vertical portion 43 is limited on the second end surface 212 and the solder leg portion 42 is located at the bottom of the main body 21.
The outer case 1 includes a cylindrical body 11 annularly disposed outside the cylindrical portion 22, a base plate 12 connected to the cylindrical body 11 and located on the top surface 210 of the main body 21, a pair of side plates 13 extending downward from the base plate 12 and corresponding to the third end surface 213 and the fourth end surface 214, respectively, and a weld plate portion 14 bent inward from the pair of side plates 13 and located on the bottom of the main body 21, wherein the weld plate portion 14 is adjacent to the protruding piece 33 in the vertical direction. Because the expanded piece 35 is formed by extending the expanded piece 33 inwards and laterally, the expanded piece 33 can not penetrate the body part 21 downwards, and short circuit fire between the expanded piece 33 and the welding plate part 14 can be avoided.
The above description is only for the purpose of describing several embodiments of the present invention, and not for the purpose of describing all embodiments, and any equivalent variations of the technical solutions of the present invention which are obvious to those skilled in the art after reading the present specification are intended to be covered by the claims of the present invention.
