The purpose of the utility model can be realized through the following technical scheme:

the utility model discloses an inner module structure of a complex terminal, which comprises a metal piece and an inner shell coated outside the metal piece;

the metal piece is of a strip-shaped structure with a plurality of bent positions and uneven width;

the two ends and/or the middle part of the metal piece are/is provided with connecting ends exposed outside the inner shell;

a plurality of raised supporting points are arranged on the inner shell;

and a waterproof ferrule is sleeved outside the supporting point.

Further, the waterproof ferrule is an elastic structure ferrule which can be compressed in both the axial direction and the radial direction.

Further, the waterproof ferrule is provided with a plurality of layers in the radial direction. The multilayer structure has enough thickness in the radial direction, so that the waterproof ferrule forms a soft sealing surface with enough area when contacting with the outer shell.

Furthermore, the supporting point is of a cylindrical, circular or frustum structure.

Furthermore, the supporting points are integrally formed on the inner shell or adhered to the inner shell.

Further, the metalwork include a plurality of plane bending segments and a plurality of vertical bending segments, promptly the utility model provides a metalwork is for having plane bending structure and the complicated type metalwork of three-dimensional bending structure. The structure of the inner shell is matched with that of the metal piece.

Based on module structure in foretell complicated terminal, the utility model discloses still protect a waterproof terminal structure of complicated type that has module structure in the above-mentioned complicated terminal, it has outer casing through the secondary cladding of moulding plastics in complicated terminal module structure is outside.

Furthermore, the inner wall of the outer shell is pressed against the supporting point.

Furthermore, the inner wall of the outer shell is pressed against the waterproof ferrule, so that the inner wall of the waterproof ferrule, the inner wall of the outer shell and the outer surface of the supporting point form a sealed cavity together. Therefore, water cannot permeate into the inner part of the sealed cavity from a gap between the supporting point and the outer shell, but at most permeates into the sealed cavity, but the upper end and the lower end of the waterproof ferrule are both tightly sealed and pressed, so that a complete waterproof function is formed, the precision and the conductivity of a final product are ensured, and the waterproof ferrule is suitable for various use environments.

Compared with the prior art, the utility model has the advantages of it is following:

1) the utility model provides a brand-new twice injection structure, through once moulding plastics before the outside rubber coating of metalwork to set up the strong point that is used for the rubber coating of second step, do abundant location to the metalwork, realized the accurate location when the secondary is moulded plastics.

2) The utility model provides a module structure has set up the support point position that has sealed protect function in complicated terminal on the inlayer casing, when satisfying accurate definite, has played the sealed and isolation protective effect that is showing, has complete waterproof function, guarantees the precision and the electric conductive property of final product, adaptable various service environment.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Examples

The utility model provides a module structure in complicated terminal, including metalwork 1 and cladding at the outside inlayer casing 2 of metalwork 1, see figure 1.

The metal member 1 is a strip-shaped structure having a plurality of bent portions and having a non-uniform width. The metal member 1 is provided with connecting ends 11 exposed to the outside of the inner shell 2 at both ends and/or at the middle portion. Metalwork 1 includes a plurality of plane bending sections 13 and a plurality of vertical bending sections 12, promptly the utility model provides a metalwork 1 is for having plane bending structure and the complicated type metalwork of three-dimensional bending structure. The structure of the inner shell 2 is matched with that of the metal piece 1.

A plurality of convex supporting points 4 are arranged on the inner shell 2; the support points 4 are externally provided with a waterproof ferrule 3, see fig. 2. The waterproof ferrule 3 is an elastic structure ferrule, which is compressible in both axial and radial directions. The waterproof ferrule 3 is provided with a plurality of layers in the radial direction. The multilayer structure provides sufficient thickness in the radial direction, so that a soft sealing surface of sufficient area is formed when the waterproof collar 3 is in contact with the outer shell 5.
