[ detailed description ] of the invention
Hereinafter, an embodiment of the electrical connector 100 according to the present invention will be described with reference to fig. 1 to 10.
Referring to fig. 1 to 10, the present invention provides an electrical connector 100, which includes an insulation body 11, a stationary terminal 2 and a movable terminal 3 fixed in the insulation body 1, and a metal housing 4 fixed outside the insulation body 1.
Referring to fig. 1 to 10, the insulating body 1 includes a base 11 and a cylindrical portion 16 extending upward from an upper surface of the base 11. Referring to fig. 9, a receiving space 12 penetrating the base 11 is transversely provided in the base 11, and two openings 14 are respectively formed in the left and right side walls of the base 11. Each opening 14 is formed with two notches 15 at lower ends of both sides of the base 11. The cylindrical portion 16 is provided with a through hole 17 penetrating the cylindrical portion 16 vertically. The through hole 17 communicates with the accommodating space 12. The connection between the through hole 17 and the receiving space 12 is defined as a docking space 18. The accommodating space 12 forms a groove 13 at the bottom end in the base 11.
Referring to fig. 7 and 8, the stationary terminal 2 includes a first body 21 having an H shape, a held portion 26 connected to the first body 21, and a first stopper 25. The first body 21 includes a first longitudinal beam 22 extending in the front-rear direction and two first cross beams 23 extending laterally at the front-rear ends of the first longitudinal beam 22, respectively. The outer edges of the two first cross beams 23 are provided with first clamping hooks 24. The first limiting portion 25 extends in the front-rear direction. The front and rear ends of the first limiting portion 25 are respectively connected between the two first cross beams 23. The first limiting portion 25 is recessed downward with respect to the first body portion 21. The abutted portion 26 is formed to extend from the inner edge of the first side member 22. The held portion 26 includes two first segments 27 extending obliquely upward from the first side member 22, and a second segment 28 connecting free ends 37 of the two first segments 27 and disposed horizontally. A hollowed-out portion 29 is formed between the two first section portions 27 and the second section portion 28.
Referring to fig. 7 and 8, the movable terminal 3 includes a second body 31 having an "H" shape, an elastic supporting portion 32 connected to the second body 31, and a second limiting portion 314. The second body 31 includes a second longitudinal beam 311 extending in the front-rear direction and two second cross beams 312 extending laterally at the front-rear ends of the second longitudinal beam 311, respectively. The outer edges of the two second beams 312 are provided with second hooks 313. The second limiting portion 314 extends in the front-rear direction. The front and rear ends of the second limiting portion 314 are respectively connected between the two second cross beams 312. The second limiting portion 314 is recessed downward with respect to the second body portion 31. The elastic supporting portion 32 includes a first elastic arm 33 extending obliquely upward from an inner edge of the second longitudinal beam 311, a second elastic arm 35 extending obliquely downward from an end of the elastic portion, a contact point 34 formed at a top end of a connection portion of the first elastic arm 33 and the second elastic arm 35, and a free end 37 extending obliquely upward from an end of the second elastic arm 35. The bottom end of the junction of the free end 37 and the second elastic arm 35 forms a sliding portion 36.
Referring to fig. 1 to 6, 9 and 10, the metal case 4 includes a main plate 41, a sleeve portion 42 extending upward from an upper surface of the main plate 41, and a clamping portion 44 extending from a side edge of the main plate 41. The sleeve portion 42 has a mounting hole 43 penetrating the sleeve portion 42 and the main plate portion 41 vertically.
In the embodiment of the electrical connector 100 of the present invention, the stationary terminal 2 and the movable terminal 3 are respectively inserted and fixed into the receiving space 12 through the openings 14 at both sides of the base 11. In order to clearly express the positional relationship between the stationary terminal 2 and the movable terminal 3, the stationary terminal 2 is inserted from the right opening 14 of the base 11, and the movable terminal 3 is inserted from the left opening 14 of the base 11, and in other embodiments, the positional relationship between the stationary terminal 2 and the movable terminal 3 may be interchanged, which is not limited herein. The first and second limiting portions 25 and 314 of the stationary and movable terminals 2 and 3 are used for soldering to a mating circuit board. The first clamping hook 24 and the second clamping hook 313 clamp the base 11 in the accommodating space 12 to fix the static terminal 2 and the movable terminal 3.
The held portion 26 of the stationary terminal 2 and the elastic holding portion 32 of the movable terminal 3 are suspended in the abutting space 18. The elastic abutting portion 32 is located below the abutted portion 26. The stationary terminal 2 remains stationary, both in the initial rest state and when the movable terminal 3 is pressed down. In the initial rest state, the elastic abutment portion 32 elastically upwardly abuts the contact point 34 against the lower surface of the second section 28 of the abutted portion 26. The second elastic arm 35 and the free end 37 of the movable terminal 3 are disposed corresponding to the hollowed-out portion 29 of the held portion 26 and transversely penetrate through the hollowed-out portion 29. The elastic abutment 32 is located directly below the perforation 17. The metal shell 4 is sleeved on the upper surface of the insulating body 1 from top to bottom. The cylindrical portion 16 is positioned in the mounting hole 43. The clamping portion 44 clamps the lower end of the base 11 to be integrally fixed.
During use, the detection probe is inserted downward from the through hole 17, and when the elastic supporting portion 32 is pressed downward by the detection probe, the elastic supporting portion 32 is elastically deformed downward as a whole to separate the contact point 34 downward from the supported portion 26, so as to promote the detection probe to be conducted with the movable terminal 3. When the elastic supporting portion 32 is elastically deformed downward, the sliding portion 36 is pressed downward against the concave recess 13 in the accommodating space 12 to form a stepped recess. As the degree of downward elastic deformation of the elastic supporting portion 32 increases gradually, the sliding portion 36 slides laterally on the groove 13, and at this time, the free end 37 and the second elastic arm 35 transversely pass through the hollowed portion 29 and do not contact with the hollowed portion 29. During use of the electrical connector 100, no portion of the movable terminal 3 other than the contact point 34 is connected to any portion of the stationary terminal 2. When the detection probe is removed, the elastic abutment 32 springs back upward to return to the original state.
Compared with the prior art, the invention has the following beneficial effects: since the sliding portion 36 is pressed against the groove 13 when the elastic pressing portion 32 is pressed down, the elastic pressing portion 32 can be supported upwards, and the elastic pressing portion 32 is prevented from being damaged due to excessive elastic deformation; further, the sliding portion 36 may slide in the groove 13, so that the elastic supporting portion 32 may be uniformly deformed downward, and damage caused by too fast elastic deformation of the elastic supporting portion 32 is avoided; furthermore, the supported portion 26 has the hollowed portion 29, so that a portion of the elastic supporting portion 32 can pass through the hollowed portion, so that the sliding portion 36 can slide conveniently, and the electric connector 100 has better structural stability as a whole, and the contact stability of the static terminal 2 and the movable terminal 3 is ensured. Because the relative position of the groove 13 is lower, the degree of the whole up-down elastic deformation of the movable terminal 3 can be reduced, and the movable terminal 3 is effectively prevented from being damaged due to excessive deformation.
The foregoing is only some, but not all, embodiments of the present invention, and any equivalent modifications of the technical solution of the present invention will be covered by the claims of the present invention by a person of ordinary skill in the art from reading the present specification.
