Embodiment

Below in conjunction with embodiment, the utility model is further described, but protection range of the present utility model is not only confined to embodiment.

As depicted in figs. 1 and 2, a kind of radio frequency (RF) coaxial connector latching structure, comprises the male 102 and female 101 that are connected together, and the outside of male 102 is arranged with push-and-pull cover 4, and described push-and-pull cover 4 can carry out the movement of axial direction relative to male 102.Male 102 is made up of parts such as male shell 9, water proof rubber circle 6, lining 7, steel ball 5, spring 8, steel wire ring 3, push-and-pull covers 4.Female 101 is made up of the part such as elastic contact head 1, shell 2.The elastic contact head 1 of female 101 uses phosphor bronze or the processing of beryllium-bronze elastomeric material, and is processed with six or eight grooves vertically for increasing elasticity.Shell 2 inside is provided with multiple stepped hole, and elastic contact head 1 is press-fitted in shell 2 second step hole.Shell 1 lateral surface is processed with a joint screw thread and a joint trapezoidal groove 21.

Male 102 has Baltimore groove 103, when male 102 and female 101 clamping, the shell 2 of female 101 is inserted in described Baltimore groove 103.Baltimore groove 103 is formed by the male shell 9 of inner side and the lining 7 in outside, and a part for male shell 9 and lining 7 links together, and a part does not connect, and the part do not connected defines described Baltimore groove 103.Male shell 9 is provided with screw thread, is also provided with screw thread in lining 7 inner chamber, by screw thread, two parts is connected and fixed.Certainly also by being press-fitted connection or two parts are processed into an entirety, and be threaded and can realize not destruction and change and cost-saving.What was certain was that, Baltimore groove 103 than coupling part closer to female 101.

Lining 7 radial direction is processed with multiple bellmouth, can processes the hole of more than 3, this example is 6, is placed with steel ball 5 in every hole, and the diameter of the less one end of bellmouth diameter is less than the diameter of steel ball 5, avoids steel ball 5 to drop.When male 102 is with female 101 clamping, shell 2 can keep being plugged in Baltimore groove 103 by steel ball 5.Therefore, along the radial direction of male 102, bellmouth, i.e. steel ball 5 are positioned at the side closer to periphery of Baltimore groove 103, and rubber ring 6 is positioned at the side closer to axial line of described Baltimore groove 103, particularly, rubber ring 6 is arranged on the lateral surface of male shell 9, and is the side communicated with Baltimore groove 103.

The diameter of the less one end of bellmouth diameter is less than the diameter of steel ball.The external diameter of lining 7 is processed with a groove, for placing steel wire ring 3, described steel wire ring 3 protrudes from the surface of lining 7.

Shown in composition graphs 4, the inner chamber of push-and-pull cover has interior stepped hole 41, intermediate step hole 42 and outer step hole 43 totally 3 joint stepped holes, the internal diameter in intermediate step hole 42 is minimum, has space between the outer wall of inner side step hole 43 and lining 7, and spring 8 is arranged in described space.Intermediate step hole 42 is between steel wire ring 3 and spring 8, and steel wire ring 3 can prop up the end in intermediate step hole 42.In normal condition and male and female head connection procedure, intermediate step hole 42 is for withstanding steel ball 5 along products radial, makes steel ball 5 adduction.Push-and-pull cover 4 is undertaken spacing by the steel wire ring 3 on lining 7, and under ensureing normal condition, push-and-pull cover 4 does not come off from male 102.

When male 102 is with female 101 clamping, a part for steel ball 5 can be stuck in described trapezoidal groove 21, makes male 102 and female 101 clamping firm.

When male and female head connects, first male push-and-pull is overlapped 4 toward post-tensioning, the right direction namely in Fig. 3, the lower end of steel ball 5 from original abut with intermediate step hole 42 to become abut with interior stepped hole 41, because interior stepped hole 41 diameter is larger, make steel ball 5 in active state, i.e. slide downward in the process.Then by male 102 with female 101 to being inserted into position, the shell of female 101 is inserted in Baltimore groove 103, and shell 2 can be inserted smoothly in moving down of steel ball 5; Again by push-and-pull cover 4 (i.e. the left direction of Fig. 3) promotion forward, the intermediate step hole 42 making internal diameter less continues to prop up steel ball 5, makes steel ball 5 to the direction of axis line adduction of male, is stuck in the trapezoidal groove 21 of female shell 2, thus realize finished product and reliably connect, see Fig. 1.During separation, by push-and-pull cover 4 toward post-tensioning, make steel ball 5 not overlap the compressing in 4 intermediate step holes 42 by push-and-pull, then pull out male 102.This operating process is simple and convenient, time saving and energy saving; After connection, tensile strength is large, does not come off.

Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
