Abstract
The invention belongs to radome design field, and in particular to connection structure and connection method of a kind of antenna house with built-in metal ring, ensure root sealer and the connection of antenna house.The present invention provides connection structure and connection method of a kind of antenna house in root and built-in metal ring, solves under harsh use environment, the connection and sealing problem of antenna house root.In antenna house process, built-in metal ring is set in composite antenna housing root, by the bonding force of composite material itself and the shaping environment of high temperature and pressure, completes the fixation to two-part structure.In order to increase two-part bonding force, it is necessary to increase two parts contact area, groove and protrusion are designed between metal connection ring and composite antenna housing cover body contact surface.Composite material cover body and metallic rings contact face coating adhesive are thermally matched under high-temperature molding environment to solve the problems, such as.Favorable sealing property.Can directly design and production.
Description
Technical field
The invention belongs to radome design field, and in particular to connection structure and company of a kind of antenna house with built-in metal ring
Method is connect, ensures root sealer and the connection of antenna house.
Background technology
In the structured design process of composite antenna housing, in order to meet interface requirements, root would generally design metal
Connection ring.Metal connection ring and the connection mode of composite antenna housing generally have two kinds：It is bonded and is spirally connected.
It is stringent to sealing performance requirement under marine environment, simultaneously as the corrosivity of marine environment is, it is necessary to bonding agent
Good with the standard component corrosion resistance that is spirally connected, this just proposes material harsh requirement.It is this in order to solve the problems, such as, just
Need to design a kind of new connection mode, that is, meet connection request, and meet sealing and corrosion resistance demand.
The content of the invention
The present invention provides connection structure and connection method of a kind of antenna house in root and built-in metal ring, solves harsh make
With under environment, the connection and sealing problem of antenna house root.
To meet rigidity and connection request, the antenna house of composite material can use metal connecting piece in its root.The present invention
Built-in metal ring is employed in antenna house process, realizes two-part connection.Can be by advance in composite material antenna
Cover root and metal connection ring is set, by the bonding force of composite material itself and the shaping environment of high temperature and pressure, complete to two
The fixation of part-structure.In order to increase two-part bonding force, it is necessary to increase two parts contact area, therefore, metal connection ring
Groove is designed between composite antenna housing cover body contact surface.Composite material cover body and metallic rings contact face coating adhesive are to solve
The certainly thermally matched problem under high-temperature molding environment.
The antenna house of the present invention uses composite material, and the antenna house root after shaping had both met built-in metal ring and antenna house
Connection, and meet that antenna house is overall and the connection of machine frame, integrally formed becket and antenna house cover body favorable sealing property.
Can directly design and production.
Brief description of the drawings
Fig. 1 is the schematic diagram of connection structure of the present invention.
Embodiment
The connection structure of antenna house and built-in metal ring, which uses composite material, in the root of antenna house 1
Surface has protrusion, have in the outer surface of built-in metal ring 4 with raised matched groove 2, there is glue on both joint faces
Stick 3, and interfix in the forming process of antenna house 1.Also there is threaded hole 5 in the outer end face of the built-in metal ring 4.
Connection mode of the antenna house of built-in metal ring and composite material in its root be：When antenna house 1 is molded, pre-buried gold
Belong to a part of the ring 4 as mould, during the demoulding, built-in metal ring 4 and antenna house 1 demould at the same time.It is hot in forming process to avoid
Mismatched caused by the coefficient of expansion is inconsistent, the coating adhesive 3 between antenna house 1 and built-in metal ring 4；To increase bonding force,
There is groove 2 in 4 contact surface of built-in metal ring, there is protrusion, groove 2 and protrusion in the contact surface corresponding with groove of antenna house 1
With reference to；To meet machine frame connection request, there is threaded hole 5 in the end of built-in metal ring 4.
Claims (4)
