Abstract

The utility model discloses a plug-in type glue-free nail-free TD-SCDMA antenna housing which mainly comprises a housing body (1), connection section bars (2) and a rear panel (3), wherein two sides of the housing body (1) and the rear panel (3) are respectively inserted into the slots of two connection section bars (2) with same symmetrical structure; the antenna housing is characterized in that two splicing edges of the housing body (1) are symmetrical and same; each splicing edge of the housing body (1) is provided with a boss (4), an upper claw (5) and a lower claw (6) which are connected to form a chicken feet shape; the boss (4) faces outwards, the lower claw (6) faces downwards and the upper claw (5) faces inwards; the connection section bars (2) are provided with chutes (7) matched with the upper claw (5) and the lower claw (6) and a chute (8) matched with the splicing edge of the rear panel (3); the upper part of the outer side edge of the chute (7) is connected with a convex edge (10) pressing against the boss (4) outwards; and an upper wing plate composing the chute (8) is provided with a sharp tooth (9) playing the sealing function and contacting the rear panel (3). The antenna housing has the advantages of self sealing and convenient and fast connection.

Description

Plug-in type is exempted from glue and is exempted from nail type radome

Technical field

The utility model relates to a kind of radome, and especially a kind of TD-SCDMA radome, specifically a kind of plug-in type are exempted from glue and exempted from nail type TD-SCDMA radome.

Background technology

As everyone knows, at present, the TD communication technology reaches its maturity, and realizes commercialization fully.The used radome of the smart antenna of one of its nucleus equipment mainly contains the branch of half cover and two kinds of forms of full cover.Proposition along with ' green ' communication theory, the fusion of active equipment and passive antenna has become one of following inexorable trend, and some device fault rate of active equipment is higher relatively, and the demand of real-time servicing is arranged, and adopting half cover to carry out Antenna Design is implementation preferably.Half cover structure adopted half cover to carry out riveted and fixed with metalwork mostly in the past, and seal at the faying face gluing, the assembly process complexity, production efficiency is low, especially when the high-gain aerial demand, along with the increase of radiating element quantity, antenna length also can extend thereupon, at this moment, number of rivets and glue consumption sharply increase, and greatly reduce the reliability of antenna.Facts have proved that through outdoor application after a while, because the inefficacy regular meeting of fluid sealant causes that antenna leaks, this problem is extensively paid close attention to.

Summary of the invention

The purpose of this utility model is partly to cover radome and the metalwork that antenna exists and need carry out riveted and fixed at existing, and the problem that needs gluing to seal, and designs a kind of by the structure self sealss and assemble simple plug-in type and exempt from glue and exempt from nail type TD-SCDMA radome.

The technical solution of the utility model is:

A kind of plug-in type is exempted from glue and is exempted from nail type TD-SCDMA radome, it is mainly by cover body 1, connection profile 2 and backboard 3 are formed, in the slot of the both sides of cover body 1 and backboard 3 two connection profiles 2 that the insert structure symmetry is identical respectively, two plug sides that it is characterized in that described cover body 1 are also symmetrical identical, be equipped with boss 4 on each plug side of cover body 1, dewclaw 5 and lower claw 6, boss 4, dewclaw 5 and lower claw 6 are connected to shank shape structure, boss 4 is outside, lower claw 6 is downward, dewclaw 5 is inside, the chute 8 that connection profile 2 is provided with the chute 7 that matches with dewclaw 5 and lower claw 6 and matches with the insert edge of backboard 3, the top of the outer side edges of chute 7 is to being externally connected with the chimb 10 that offsets with boss 4, the upper flange of forming chute 8 be provided with seal with backboard 3 contacted pointed tooths 9.

Described connection profile 2 is an aluminium section bar pultrusion structural member.

The quantity of described pointed tooth 9 is no less than 2.

The beneficial effects of the utility model:

1. radome of the present utility model adopts mold design all, produces, the production efficiency height, and highly versatile is applicable to the antenna of multiple model, multiple series.

2. radome of the present utility model adopts the plug in construction design, need not riveted joint, and assembly technology is simple, and the production efficiency height is fit to produce in enormous quantities.

3. radome of the present utility model adopts structure self sealss design, need not the gluing sealing, good airproof performance, and the antenna integral surface is totally attractive in appearance.

Description of drawings

Fig. 1 is the structural representation of radome of the present utility model.

Fig. 2 is the structural representation of the plug side of cover body of the present utility model.

Fig. 3 is the section structure schematic diagram of connection profile of the present utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As Figure 1-3.

A kind of plug-in type is exempted from glue and is exempted from nail type TD-SCDMA radome, it mainly is made up of cover body 1, connection profile 2 and backboard 3, as shown in Figure 1, in the slot of the both sides of cover body 1 and backboard 3 two connection profiles 2 that the insert structure symmetry is identical respectively, cover body 1 adopts pultrusion, and its two plug side symmetries are identical, and its cross section is provided with boss 4, dewclaw 5 and lower claw 6, its shape exactly likes shank, as shown in Figure 2; The connection profile 2 that matches with cover body 1 (can adopt aluminium section bar) adopts hot extrusion molding, its Cross section Design has chute 7, chute 8 and pointed tooth 9, the top of the outer side edges of chute 7 is to being externally connected with the chimb 10 that offsets with boss 4, seal with backboard 3 contacted pointed tooths 9 be positioned at the upper flange of forming chute 8 in the face of on the side of chute 8.The last lower claw of cover body 1 is through in the chute 7 of aluminium section bar 2, and boss 4 is bearing on the chimb 10 of aluminium section bar 2, by the gap between suitable adjustment chute 7 and the last lower claw, can guarantee that cover body 1 is free to slide with convenient for assembly at length direction, again can positiver sealing.Backboard 3 is an aluminium section bar, adopt hot extrusion molding, thickness is 2mm, it is through in the chute 8 of aluminium section bar 2, pointed tooth 9 highly is 1mm, and quantity can guarantee that equally backboard 3 is free to slide and positiver sealing at length direction more than 2 or 2, the plug side of backboard 3 upwards has a warpage, so the upper flange of chute 8 correspondingly has a downward sedimentation (as the limit portion 11 of the upper flange among Fig. 3).

Radome of the present utility model can all adopt mold production, so can be according to different antenna requirements, produce the radome of the different length that matches with it fast and effectively, and all adopt the plug-in type assembling, need not the gluing sealing, not only assembly technology is simple, good airproof performance, and has increased the reliability of antenna greatly, has guaranteed that the antenna integral surface is totally attractive in appearance.

The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
