Abstract

The utility model relates to a ring-shaped fastening piece which is used for fastening and connecting cables (wires, nets, pipes) and a collector. The shape of a fastening ring is a circular shape, a rectangle, a hexagon, or a polygonal shape, and the cross section shape of the ring is a circular shape, a rectangle, a triangular, a parallelogram, or a polygonal shape. Fastening shrinkage can be realized by instantaneously heating by utilizing shape memory alloy materials which have reminiscence recovery property, and uniform fastening force can be generated within the range of 360 DEG. The fastening ring has the characteristics of simple and fast operation, uniform stress and good fastening performance. The utility model is particularly suitable for the connection of a shielded cable and an electric connector, and the connection part has better mechanical property and electronic performance with high frequency.

Description

The marmem retaining ring
The utility model relates to a kind of marmem retaining ring that ring part is fastenedly connected usefulness that is mainly used in, and belongs to a kind of connecting element.
Up to the present, the connection that is used for cable, line, net, pipe mainly is that manual type mechanical connects, General fasteners is fastening or plastic deformation is fastenedly connected, and their common shortcomings are: 1. inconvenient operation, when particularly little space intensity is fastenedly connected; 2. fastened place discontinuity causes the conformity of the surface of contact contact pressure that must closely contact poor; 3. endurance is relatively poor relatively, and it is easily loosening to do the time spent in extraneous factors such as tension force, impact or vibration are arranged.
The purpose of this utility model is a kind of marmem retaining ring of design, utilizes the reminiscence characteristic of marmem, realizes being fastenedly connected, and is easy and simple to handle, quick, and fastening effective.
The marmem retaining ring that the utility model is designed be shaped as circle, rectangle, Hexagon or polygonal.
The sectional shape of the marmem retaining ring that the utility model is designed be circular, class is oval or oval, rectangle or square, triangle, quadrilateral or polygonal.
The section area of the marmem retaining ring that the utility model is designed is 1mm 2~1256mm 2In the scope.
The girth of the marmem retaining ring that the utility model is designed is in 5~1000mm scope.
The designed marmem retaining ring of the utility model adopts TiNiNb, TiNi, TiNiFe, CuZnAl, marmems such as CuAlNi, FeMnSi to make.
When using the designed marmem retaining ring of the utility model, retaining ring is enclosed within is connected the place and retaining ring heated, retaining ring shrinks because of reminiscence, simultaneously can be around produce certain positive pressure on the Normal direction in 360 ° of scopes, thereby realize being fastenedly connected of connected piece.
This retaining ring also can be used for being fastenedly connected of non-slick and sly annular surface except that the connection that is used for cable, line, net, pipe.Especially for being connected of shielded cable and electric coupler or connector assembly, can make the joint have extraordinary mechanical property and desirable high-frequency electronic performance.
The advantage of the marmem retaining ring that the utility model is designed is: simple and efficient to handle, stressed evenly tightness is good, connects reliably, still can be lastingly fastening loosening when extraneous tension force, impact, oscillating action are arranged.
Fig. 1 is the outline drawing of the designed round-shaped memory alloy retaining ring of the utility model.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the working state figure of the designed marmem retaining ring of Fig. 1
Fig. 4 is the schematic representation of non-circular shape memory alloy retaining ring.
Fig. 5 is the noncircular cross section schematic representation of marmem retaining ring.
In conjunction with specific embodiments the shape and the application characteristic of the designed marmem retaining ring of the utility model is described further with reference to the accompanying drawings below.
Embodiment 1
The marmem retaining ring designed as Fig. 1 can be made by the TiNiNb memory alloy material, and it is shaped as circle, and girth is 145mm, and its cross section is circular, and as shown in Figure 2, section area is 28mm 2This ring user mode as shown in Figure 3, be fastenedly connected electric coupler (connector assembly) 2 and mask net 3 with marmem retaining ring 1, the link position that during use retaining ring is enclosed among Fig. 3 heats it, retaining ring 1 recovers to shrink because of shape-memory, on mask net 3 and electric coupler 2 contacted annular surfaces, produce positive pressure (fastening force), realize being fastenedly connected of connected piece.This Placement can make fastening force evenly distribute in 360 ° of annular surface scopes, make the place of being connected have extraordinary mechanical property: the fastening strength of 1 pair of mask net 3 of retaining ring is greater than self intensity of mask net 3, do the time spent at extraneous tension force, retaining ring 1 can not pulled yet when mask net 3 was broken, more can be not loose because of temperature variation (60 ℃~200 ℃).In addition, the D.C. resistance of connected system is less than 1m Ω when connecting owing to retaining ring 1, and native system has desirable high-frequency electronic performance again.
Embodiment 2
The profile of marmem retaining ring can also be designed to the rectangle of a figure as shown in Figure 4, the Hexagon of b figure, the girth of marmem retaining ring is difference 1000mm, 600mm, make by the TiNi memory alloy material, the usage mode of the marmem retaining ring that its usage mode and embodiment 1 are designed is identical, have simple and efficient to handle equally, stressed evenly, advantage such as tightness is good.Its difference is that the polygonal retaining ring can have stronger specific aim at the requirement design of non-circular curved surface.
Embodiment 3
The cross section of designed marmem retaining ring can also be the sectional shape designed as Fig. 5 among the embodiment 1,2, scheme wherein that a class is oval or oval, figure b is that rectangle, figure c are that triangle, figure d are parallelogram, the area in its cross section is respectively 1200mm 2, 50mm 2, 8.6mm 2, 30mm 2Can select the marmem retaining ring of different cross section according to the concrete needs that are connected element.The noncircular cross section retaining ring is that than the difference of circular cross-section retaining ring the area of contact at fastening place is big, more helps fastening or sealing.
The marmem retaining ring can store transportation under-196 ℃~+ 60 ℃ ambient temperatures, realize can keeping permanent fastening not loose behind the terminal operation in-60 ℃~+ 200 ℃ scopes.This shows that the memory alloy retaining ring is a kind of connecting element of new type ideal.

Claims (4)

1. marmem retaining ring is characterized in that: ring be shaped as circle, rectangle, Hexagon or polygonal.
2. marmem retaining ring according to claim 1, its feature also is: the sectional shape of ring for circular, class is oval or oval, rectangle or square, triangle, quadrilateral or polygonal.
3. marmem retaining ring according to claim 1, its feature also is: the section area of ring is 1mm 2~1256mm 2In the scope.
