Description
Technical Field

As shown in fig. 1 to 3. The conventional soft waveguide assembly includes: flange 1, rubber sleeve 2 and pipe embryo 3. In order to increase the strength of the rubber at the interface with the flange, it is common practice to increase the wall thickness of the rubber sleeve 2.
However, the increase in thickness of the rubber sleeve tends to reduce the curvature of the waveguide, increase in rubber material, and increase in cost. In addition, the thicker the rubber sleeve is, the larger the stress is in bending, the strength of the joint is improved, but the breaking force is correspondingly increased, and the damage of the joint is not completely eliminated.

Detailed Description
The invention is further described below with reference to the drawings and specific embodiments.
As shown in fig. 4 to 7, the soft waveguide assembly includes: flange 10, jacket 20 and waveguide blank 30.
The flange 10 is rectangular and has a central stepped hole 11, a fixing groove 12, a connection boss 13 and screw holes 14. One end of the waveguide tube blank 30, which is also rectangular, is disposed in the central stepped bore 11 of the flange 10.
In this embodiment, the material of the sheath 20 is rubber. The four sides of the sheath 20, which are located against the flange, each have a reinforcement. Of course, if the curvature is not great, the stiffening elements may be provided in only two, symmetrically on opposite sides.
The reinforcement includes: a straight section 21, an inclined section 22 and a transition section 23.
The straight section 21 is semicircular in cross section. The semicircle is tangential to the largest outer circle of the fastener 14-1 with which the screw hole 14 is provided. The largest fastener 14-1 may be a nut or a washer; mainly to leave the place where the fastener is installed. As shown in fig. 7, the inclined section 22 forms an angle α with the straight section 21, and the inclined section forms an angle α with the insulating elastic tube in a range of 5 degrees to 15 degrees, preferably 8 degrees, 10 degrees, 12 degrees or 13 degrees. The length B of the inclined section is 2 to 5 times, preferably 3 to 4 times, the length a of the straight section. The straight section 21 and the inclined section 22 form a fin-shaped reinforcement.
The transition section 23 is a quarter circular arc with the same diameter size as the outer circle of the screw washer 14-1. The transition section 23 can also be understood as a rounded corner of the edge of the straight section 21 and the sheath 20, and has the function of smooth transition, so as to eliminate the connection stress. The coupling boss 13 of the flange 10 conforms to the outer shape of one end of the sheath 20.
Of course, if the entire end face of the flange 10 is relatively large, the straight section 21 of the stiffener may not be tangential to the largest outer circumference of the fastener 14-1, with some clearance therebetween.
The sheath 20 is sleeved outside the waveguide tube blank 30; and is fixed in the fixing groove 12 of the flange 10. One end of the sheath 20 is abutted against the connection boss 13 of the flange 10.
Performance of the soft waveguide assembly:
under the condition that the original assembly environment is not affected, the strength of the joint between the sheath and the flange is increased and the service life of the joint is prolonged by adding the reinforcing part to the sheath. The structure of the stiffener maximizes the utilization of the flange mounting face.
The strength of the interface between the sheath and the flange is enhanced only at the joint, and the integral wall thickness increase of the sheath is not required. Therefore, the wall thickness C of the whole sheath is effectively reduced, the bending degree is increased, the stress is reduced during bending, and the rubber material is also reduced.
