Description

The cab over type coaxial cable connector

The utility model relates to a kind of coaxial cable connector, particularly relates to the cab over type coaxial cable connector that a kind of body terminal forms planar portions.

The inventor had once proposed the patent application of F type cab over type coaxial cable connector on December 4th, 1998 to the U.S., was checked and approved patent at present.The body of original coaxial cable connector is with the fixing plastic terminal of riveted mode, or behind plastic terminal a sheathed gasket ring and give riveted.For overcoming the many disadvantages that above structure causes, above-mentioned patent application case forms a planar portions with body two lateral terminals, can keep the smooth of adjacent surface when making it to combine with terminal F male joint, leaks to prevent electric wave.

Only when further manufacturing experimently, the inventor finds that the means for mounting coupling parts before changing between case body accommodation hole and the terminal second insulation external member can significantly reduce cost and improves process velocity, and can make body two lateral terminals formation planar portions equally.

The purpose of this utility model promptly is to provide a kind of simple in structure, easy cab over type coaxial cable connector of assembling, so that the second insulation external member of terminal structure firmly build-in in the accommodation hole of body, simultaneously significantly reduce its manufacturing cost and improve its process velocity.

To achieve these goals, the utility model forms in the accommodation hole of body and can make the terminal structure second insulation external member embed fixing annular clip teat; Perhaps dispose an annulus at the body openings place and make the terminal of body form planar portions, define a through hole in the ring sleeve, formation can make the terminal structure second insulation external member embed fixing annular clip teat in the through hole.

In the utility model, no matter be annular clip teat to be set or in the body accommodation hole at body openings place configuration annulus, all can make the terminal structure second insulation external member firmly build-in in the body accommodation hole, and simple in structure, easily assembled.

Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model cab over type coaxial cable connector.

With reference to illustrated in figures 1 and 2, the utility model cab over type coaxial cable connector mainly comprises body 10 and terminal structure 20.

As shown in Figure 3, body 10 comprises threaded portion 11, hexagonal body 12, first planar portions 13 and second planar portions 14.Body 10 defines an accommodation hole 15, and its diameter dimension can hold terminal structure 20.The inside of accommodation hole 15 ends at the bottom of the annular flat 16, form an annular clip teat 17 in the accommodation hole 15 of contiguous second planar portions 14 to embed fixing terminal structure 20, the outside of clip teat 17 has taper portion 18, so that terminal structure 20 is easy to insert accommodation hole 15.

As shown in Figure 4, terminal structure 20 comprises the first insulation external member 21 and the second insulation external member 22, the first insulation external member 21 and the second insulation external member 22 have annular

outer diameter part

23,24 and elastic

ring clamping part

25,26 respectively, be arranged with tubulose contact element 27 between the

clamping part

25,26, formation one insertion mouth inserts to form for terminal F male joint conductor and is electrically connected near the terminal of contact element 27.The first insulation external member 21 and the second insulation external member 22 can be made by plasticity plastic cement (as PE, PP, PC etc.) or rubber.

During the assembling of cab over type coaxial cable connector, at first terminal structure 20 is inserted in the accommodation hole 15 of body 10, up at the bottom of the first insulation terminal of external member 21 and the annular flat 16 flush till, because the relative dimensions that the accommodation hole 15 and the second insulation external member are 22, annular clip teat 17 and second insulate and combines because of compression stress forms embedding between external member 22 appearances, as shown in Figure 1, so terminal structure 20 firmly can be fixed in the body 10, and make coaxial cable connector can keep the smooth of adjacent surface when combining with terminal F male joint, leak to prevent electric wave.

With reference to shown in Figure 5, the utility model cab over type coaxial cable connector mainly comprises body 30, terminal structure 20 and annulus 40.

As shown in Figure 6, body 30 comprises threaded portion 31, hexagonal body 32, first planar portions 33 and opening part 34.Body 30 defines an accommodation hole 35, and its diameter dimension can hold terminal structure 20, and accommodation hole 35 inside end at the bottom of the annular flat 36, are formed with a cannelure 37 in the accommodation hole 35 of opening part 34 terminals, and cannelure 37 inside end at the bottom of the annular flat 38.

As shown in Figure 4, terminal structure 20 comprises the first insulation external member, 21, the second insulation external member 22 and tubulose contact elements 27.

As Fig. 4 and shown in Figure 7, annulus 40 defines a through hole 41, the terminal of this through hole 41 has an annular clip teat 42, fix the second insulation external member 22 with embedding, clip teat 42 forms taper portion 43 with the joint face of through hole 41, so that the first insulation external member 21 and the second insulation external member 22 are easy to insert through hole 41.

During assembling, at first annulus 40 is pressed in the cannelure 37 of body 30, up at the bottom of the terminal of annulus 40 and the annular flat 38 flush till, thereby annulus 40 is combined with cannelure 37, so can make the opening part 34 of body 30 form a planar portions 39, as shown in the figure.At last, terminal structure 20 is inserted in the accommodation hole 35 of body 30, up at the bottom of the first insulation terminal of external member 21 and the annular flat 36 flush till, because the relative dimensions of the accommodation hole 35 and the second insulation external member 22, annular clip teat 42 combines because of compression stress forms embedding with the appearance of the second insulation external member 22, as shown in Figure 5, so terminal structure 20 firmly can be fixed on body 30 inside.

With reference to shown in Figure 9, the utility model cab over type coaxial cable connector mainly comprises body 30, terminal structure 50 and annulus 60.

As shown in figure 10, terminal structure 50 comprises the first insulation external member 51, second insulation external member 52 and the tubulose contact element 53.The first insulation external member 51 and the second insulation external member 52 can be made by plastic cement material, and annular outer diameter part 54 outer surfaces of the second insulation external member 52 are formed with an annular groove 55.

As shown in figure 11, through hole 61 made and defined by annulus 60 by metal material, has an annular clip teat 62 in this through hole 61, make it and to be fixed with the annular groove 55 of the second insulation external member 52, clip teat 62 forms a taper portion 63 with the joint face of through hole 61, so that the first insulation external member 51 and the second insulation external member 52 are easy to insert through hole 61.

As Fig. 6 and shown in Figure 11, during assembling, at first annulus 60 is pressed in the cannelure 37 of body 30, up at the bottom of the terminal of sleeve 60 and the annular flat 38 flush till, thereby sleeve 60 is combined with cannelure 37, so can make the opening part 34 of body 30 form a planar portions 39.At last, terminal structure 50 is inserted in the through hole 61 of sleeve 60, up at the bottom of terminal and the annular flat of the first insulation external member 51 36 flush till, can make so that annular groove 55 and clip teat 62 are mutual to engage and form the location, thereby terminal structure 50 firmly is fixed on body 30 inside.

In sum as can be known, the utility model is established annular clip teat or at body openings place configuration annulus in the body accommodation hole, all can make terminal structure firmly build-in in body and make the terminal of body form the plane, thereby can keep when body is combined with terminal F male joint adjacent surface smooth, prevent that electric wave from leaking.And the utility model is simple in structure, assembling is simple and easy, can significantly reduce cost and improve process velocity.
