Description

Conserve space type round electric connector

Technical field

Utility model belongs to technical field of electric connectors, especially belongs to conserve space type round electric connector.

Background technology

The product that flies for going up to the air comprises for the parts, in order to reach and to realize the product excellent performance, during design always by every possible means pass through the overall dimension that various means reduce product, cut down the consumption of energy to alleviate product weight, this connector is just in order to realize installing in the radial direction designing in the cylinder of certain flight.

Summary of the invention

The purpose of this utility model, mainly be on direction, to install, reduce flight resistance, the little conserve space of overall dimension, lead for the barrel bore that can be implemented in flight to draw and to change direction, sealing, easy to assembly, problem such as electric performance stablity is reliable as required, a kind of concision and compact be provided, assemble conserve space type cylindrical connector easily.

This connector mainly is made up of parts such as shell, insulator component (being commonly called as the pedestal component), sealing gasket, hood component, attachment screws, and the connector construction main feature is the profile characteristics with anti-rotation structure and arc-shaped curved surface of being connected that connect hood, hood component and the shell of lobe formula.Connector is installed in the cylinder by two sunk screws, has realized the sealing of connector and cylinder by the sealing gasket between shell and the cylinder inner wall, and the generation of large drag forces when the tangent arc-shaped curved surface of outer cylinder has been avoided flight in connector shell and the cylinder; Bindiny mechanism by similar collar formula is set on shell and hood component and anti-rotation structure have been realized being connected of shell and hood component; and the structural design of symmetrical expression; when changing the direction of hood component, then realize the commutation of cable; and draw aspect the protection at lead; then avoid traditional independent lines clamping structure; by hood inside is hollowed out; reserve an aperture at the hood afterbody; after the connector assembling; poured into fluid sealant in the hood in the past; so that better protection is drawn lead, increase the reliability of connector.

Adopt the beneficial effect of the technical program in a word: realize the installation of cylinder radial direction, conserve space, lead is drawn and can be commutated, and easy to assembly, electric property is reliable and stable.

Embodiment

Now in conjunction with the accompanying drawings the embodiment of conserve space type round electric connector described in the utility model is further described:

The barrel bore that can be implemented in product for connector is to installation, and it mainly comprises installs tube 1, connector 2, installing hole more than 3 parts.Shown in Fig. 1 a, Fig. 1 b, connector 2 is made up of contact 21, pedestal 22, sealing gasket 23, shell 24, interfacial seal pad 25, lock-screw 26, hood a27, hood b28, as Fig. 2 a, Fig. 2 b.

Shell mechanism such as Fig. 3 a, shown in Figure 4, mainly by link slot 31a, the shell anti-rotation is cut connection and the rotation-preventing mechanism that flat 32a forms shell, the upper end of shell is provided with the sealing that arc passes through curved surface 33 mutually and realizes and install tube 1 with half formula seal groove and rubber ring, hood a27 and hood b28 are made up of the component cooperation of two halves formula symmetry, which is provided with hood annular convex rib 31b and cut being connected of flat 32b composition hood with the hood anti-rotation, the anti-link slot 31a that passes mechanism shell cooperates formation bindiny mechanism with the hood annular convex rib 31b of hood, the shell anti-rotation cuts flat 32a and the hood anti-rotation is cut flat 32b composition rotation-preventing mechanism.Side on the hood also is provided with wire hole 34, and the bottom is provided with embedding hole 35.

This structure way of realization can have numerous variations according to different occasions with overall dimension, but does not all influence the essence of this connector construction.

As Fig. 2 a, shown in Fig. 2 b, according to the relative dimensions that tube is installed the installation curved surface of product is adjusted, for the syndeton that reduces product size spatial enclosure and hood is avoided common flange connection, but by the shell tail end shell link slot 31a is set and the shell anti-rotation is cut flat 32b (see figure 4), the hood dimidiation (is seen Fig. 5 a, Fig. 5 b), and hood annular convex rib 31b and hood anti-rotation that similar Spring Clip is set on hood are cut flat 32b, but different with Spring Clip is, this structure had both realized axial connection, realized anti-rotation again, also abandoned the shortcoming of Spring Clip simultaneously at circumferencial direction size big and non-dismountable (or dismounting is inconvenient), it is comparatively convenient to assemble, when the two halves hood unites two into one (as Fig. 3 a, Fig. 3 b) just realized being connected and anti-rotation of hood and shell, and commutation (180 ° of the commutation angles) problem that the symmetric design of anti-rotation and syndeton is drawn the connector lead is readily solved, the usage space that this structural design is all saved connector on circumferencial direction and the axis direction greatly, in addition, again by hood being designed to the thin-wall part of hollow out, created advantage for alleviating product weight, in addition, two halves formula structure also has assembly and disassembly advantage easily, the main inherent characteristics of Here it is this connector.The arc that passes through mutually with cylinder is installed by curved surface and seal groove then is this connector construction external feature, also by the arc that passes through mutually curved surface, seal groove and rubber ring is installed just and has been realized product and the sealing that tube is installed.
