[ detailed description ] embodiments

An embodiment of the rf connector 100 of the present invention is described in detail below with reference to fig. 1 to 6. For convenience of description, all the following descriptions related to the directions of the upper, lower, left and right are referred to fig. 1.

Referring to fig. 1 to 6, the rf connector 100 of the present invention is used to match with a test probe, and includes an insulator, a moving terminal 4 integrally formed on the insulator, a static terminal 3 normally kept in contact with the moving terminal 4, and a metal shell 5 covering the insulator.

The insulator comprises a flat insulating base body 1 and an insulating cover body 2 positioned on the insulating base body 1. In this embodiment, the insulating cover 2 is clamped to the insulating base 1.

Referring to fig. 3 to 6, the insulating base 1 is made of a plastic material, and the insulating base 1 includes a first terminal groove 11 for accommodating the fixed terminal 3, a second terminal groove 12 for accommodating the movable terminal 4, a holding groove 13 extending along a transverse direction between the first terminal groove 11 and the second terminal groove 12, a supporting groove 14 extending along a longitudinal direction and orthogonally disposed with the holding groove 13, through holes 15 penetrating through the upper and lower surfaces of the insulating base 1 and located around the holding groove 13 and the supporting groove 14, and reversed latching grooves 16 located at two sides of the longitudinal direction of the holding groove 13 and located at the bottom surface of the insulating base 1. The first terminal groove 11 and the second terminal groove 12 penetrate through the upper surface and the lower surface of the insulation seat body 1 from top to bottom. The holding groove 131 is inclined from top to bottom from the second terminal groove 12 to the first terminal groove 11. The holding groove 131 is located at the center of the insulation housing 1. The retaining grooves 14 are inclined from top to bottom from the longitudinal two sides of the insulating base body 1 to the center. The through hole 15 is located in a step portion formed by the downward depression of the upper surface of the insulation base body 1.

Referring to fig. 3 to 6, the insulating cover 2 is disposed on the insulating base 1 and includes a base 21, a cylindrical abutting portion 22 formed by protruding upward from the middle of the base 21, a bottom plate 23 fixed at the bottom of the base 21, a locking block 24 protruding upward and outward from a side of the bottom plate 23 corresponding to the stationary terminal 3, and four locking posts 25 protruding downward from the bottom plate 23. The butt joint hole 221 is formed through the middle of the butt joint part 22. The docking hole 221 is for insertion of a test probe. The bottom plate 23 is provided with a through hole 231 penetrating the abutting hole 221. A contact piece 241 for contacting the stationary terminal 3 is formed to protrude downward from the lower surface of the engaging piece 24. The upper surface of the engaging piece 24 protrudes upward from the upper surface of the base 21. The clamping column 25 is sleeved into the through hole 15 of the insulating base body 1.

The static terminal 3 is formed by punching a metal sheet. The fixed terminal 3 is in a step shape, and includes a first fixing portion 32 integrally formed on the insulating base 1, a first welding portion 33 extending outward from a lower end of the first fixing portion 32, and a first contact portion 31 extending inward from an upper end of the first fixing portion 32. The first fixing portion 32 is formed by bending the lower end of the first contact portion 31 downward and embedded in the first terminal groove 13 of the insulating base 1. The first contact portion 31 is formed by bending the fixed terminal 3 after it is formed on the insulating housing 1, so that the first contact portion 31 is precisely contacted with the movable terminal 4. The first fixing portion 32 is provided with a first holding arm 321 integrally formed between the insulating base 1 and the first fixing portion 32. The first holding arm 321 is wing-shaped. In the present embodiment, the first holding arm 321 extends obliquely toward the movable terminal 4. The first holding arm 321 is vertically disposed. The first soldering portion 33 extends out of the insulating housing 1 for soldering and fixing with a docking circuit board (not shown). The non-horizontal arrangement means that the first holding arm 321 and the first fixing portion 32 are not on the same horizontal plane. The non-perpendicular arrangement means that the included angle between the surface of the first fixing portion 32 and the surface of the first holding arm 321 is not 90 degrees. In this embodiment, an included angle between the plane 321 where the first holding arm is located and the plane where the first fixing portion 32 is located is 45 degrees. The width of the free end of the first holding arm 321 in the vertical direction is greater than the width of the root of the first holding arm 321. The distance between the roots of the pair of first holding arms 321 is smaller than the distance between the free ends of the pair of first holding arms 321. When the movable terminal 4 receives an external force from top to bottom, the fixed terminal 3 also receives a force in the vertical direction from top to bottom, and the first holding arm 321 is arranged obliquely at the moment, so that the force in the vertical direction can be dispersed into the insulating base 1, and the risk that the first holding arm 321 is broken due to excessive force is reduced.

The movable terminal 4 includes a second contact portion 41 abutting against the first contact portion 31, a second fixing portion 42 connected to the second contact portion 41 and accommodated in the second terminal groove 12 of the insulating base 1 after being mounted, a pair of second fixing arms 421 fixed to the insulating base 1 and formed by extending the second fixing portion 42 from the longitudinal two sides obliquely from outside to inside, a second welding portion 43 bent downward from the other end of the second fixing portion 42 and then bent horizontally, an extension arm 44 formed by folding and extending from the two sides along the direction perpendicular to the extension direction of the second fixing portion 42 and located in the abutting groove 14, and an abutting portion 45 located at the junction of the extension arm 44 and the second fixing portion 42 and used for contacting with the test probe. The second fixing portion 42 of the movable terminal 4 is integrally formed on the insulating housing 1. The second welding portion 43 is formed to extend outward from the lower end of the second fixing portion 42. The second contact portion 41 is formed to extend inward from the upper end of the second fixing portion 42 and is normally held in contact with the first contact portion 31. The second contact portion 41 is exposed in the mating hole 221 of the insulator. The movable terminal 4 is a cantilever beam structure as a whole, the extending arms 44 extending from both sides are simply supported beam structures, and the free ends of the pair of extending arms 44 are abutted against the insulating base 1. The free end of the extension arm 44 is inclined upwards to abut on the insulation base 1 to provide a positive force. The movable terminal 4 is formed by bending and pressing an elastic nickel-copper alloy plate into a predetermined shape. The second soldering portion 43 extends out of the insulating housing 1 for soldering and fixing with a docking circuit board (not shown). The second holding arm 421 is integrally formed in the insulator and is disposed non-horizontally and non-vertically with the second fixing portion. The non-horizontal arrangement means that the second holding arm 421 and the second fixing portion 43 are not on the same horizontal plane. The above non-perpendicular arrangement means that the included angle between the surface of the second fixing portion 42 and the surface of the second holding arm 421 is not 90 degrees. In this embodiment, an included angle between a plane where the second holding arm 421 is located and a plane where the second fixing portion 42 is located is 45 degrees. The second holding arm 421 is vertically disposed. The width of the free end of the second holding arm 421 in the vertical direction is greater than the width of the root of the second holding arm 421. The distance between the roots of a pair of said second retaining arms 421 is smaller than the distance between the free ends of a pair of said second retaining arms 421.

The static terminal 3 and the movable terminal 4 are integrally formed on the insulation base 1.

The metal shell 5 is made of a metal material, and includes a substrate 51, a socket portion 50 formed by extending the middle of the substrate 51 upward, and locking portions 52 located at two longitudinal sides of the metal shell 5 and formed by bending downward and extending inward from the substrate 51. The metal housing 5 is provided with a holding notch 511 which is engaged with the engaging block 24. The surface of the substrate 51 and the surface of the engagement block 24 are located on the same plane. The vertical direction of the locking part 52 is provided with a through hole part 512 penetrating through the front and rear surfaces of the locking part 52 and connecting feet 53 positioned at both sides of the through hole part 512 and connecting the base plate 51 and the lower end of the locking part 52. The bottom surface of the locking portion 52 is locked to the locking guide groove 16.

The movable terminal 4 of the rf connector 100 of the present invention is provided with a wing-shaped extension arm 44, which provides a reliable positive force to make the pressing portion 45 obtain a strong elastic force. The first fixing portion 32 and the second fixing portion 42 of the movable terminal 4 and the stationary terminal 3 of the rf connector 100 of the present invention are provided with the first holding arm 321 and the second holding arm 421, which are wing-shaped and are disposed in an inclined manner, so as to increase the adhesive-grasping force between the first holding arm 321 and the second holding arm 421 and the insulating base 1, and increase the holding force between the stationary terminal 3 and the movable terminal 4 and the insulating base. When the test probe is inserted into the mating hole 221 from top to bottom, the test probe abuts against the second contact portion 41, and at this time, the second contact portion 41 is pressed downward to be away from the first contact portion 31, that is, the second contact portion 41 and the first contact portion 31 are separated from each other, and the movable terminal 4 bears a vertical force, and since the second holding arm 421 is obliquely arranged from the second holding portion 42 to the stationary terminal 3, the force borne by the second holding arm 421 is dispersed on the insulating base 1, so that the risk of breaking the second holding arm 421 due to an excessive force is reduced, and meanwhile, due to the arrangement of the second holding arm 421, the movable terminal and the insulating base 1 can be better combined. The first holding arm 321 is arranged similarly. In the present embodiment, since the test probe directly applies a force to the movable terminal 4 and the second contact portion 41 of the movable terminal 4 is located under the first contact portion 31 of the fixed terminal 3, only the second holding arm 421 on the movable terminal 4 may be disposed instead of the first holding arm 321, or both may be disposed.

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.
