The connector assembly can also include the shielding element 7 for providing electromagnetic shielding, as depicted in figs. 1 and 2, shielding member Part 7 includes the side shield part 77 for being arranged at the both sides of pin sidepiece part 1 and connector sidepiece part 4, the side shield part 77 Such as extend along X-direction.As shown in Fig. 2 shielding element 7 can further include the multiple pin sides for being covered in and being arranged side by side The face shield member 76 of the one or both sides of part and the combination of connector sidepiece part, is thus surrounded according to the utility model embodiment Connector assembly；Face shield member 76 can be attached or secured on side shield part 77 by modes such as screw, buckles.

Referring to Fig. 1, Fig. 2 and Fig. 4, the connector assembly also includes being arranged on the first rear portion 21 and the second rear portion 51 at least One or both of end clamping element 200.Clamping element 200 each includes at least one opening 203, and opening 203 is used to pass through One cable 215 with the corresponding rear portion 51 of first rear portion 21 or second to connect.Clamping element 200 also includes corresponding to each opening Grip flange for clamping the cable 215 that passes through from opening 203.

In the connector assembly, for example, corresponding to each connection pole, set on the first rear portion 21 and/or the second rear portion 51 Connector 27 and/or connector 57 are equipped with, then correspondingly clamping element 200 is arranged on connector 27 or 57, such as is arranged on simultaneously Arrange on the multiple connectors 27 or 57 set.For example, the quantity of the opening of clamping element 200 and the quantity phase of connector 27 or 57 Deng cable 215 is connected by the opening 203 of clamping element 200 with connector 27.

As shown in figure 4, clamping element 200 includes the body 250 extended laterally, body 250 has alar part respectively in its both sides 251, on the whole can be u-shaped.Body 250 is, for example, plate-like piece, and multiple for example circular openings 203 are formed in plate face.Each Alar part 251 has erecting bed 252 for installation, fixed clamping piece 200.Clamping element 200 corresponds to each opening 203 and is provided with Grip flange, the grip flange such as be connected through a screw thread, mode clamping is installed, is fixed on body 250.

For example, in clamping element, include upper flange positioned opposite to each other corresponding to the grip flange of each opening 203 204 and lower flange 205.The upper flange 204 and lower flange 205 are relative to each other in the vertical, and are arranged in pairs, such as the upper flange 204 and lower flange 205 all include the recessed portion of approximate half-circular (i.e. first quarter moon shape).Described below by taking upper flange 204 as an example, Lower flange 205 can have identical structure.

As shown in figure 4, upper flange 204 is in arch bridge shape on the whole, its recessed portion corresponds to opening 203.For upper flange 204, there is installation portion at both ends, the through hole extended longitudinally or screw 2111 are formed in the installation portion；Have at middle part convex Platform 2102, formed with the through hole 2101 axially extended in the boss 2102, the through hole 2101 is in the horizontal stroke perpendicular to X-direction Section is, for example, sports filed track shape, i.e., among be square and both sides are semicircle, be inserted into so as to work as bolt or latch After in the through hole 2101, can still there is certain activity surplus in the vertical；Opening 214 is formed respectively in boss both sides；In Portion rearward position is formed with opening 2071.

By forming the through hole extended longitudinally or screw 2111 in installation portion, two two longitudinal register pins can be used Upper flange 204 and lower flange 205 positioned opposite to each other are fixed (for example, bolt) 211, that is, two longitudinal directions are determined Position pin is being upward through upper flange 204 and lower flange 205 perpendicular to the side in the first posterior axis M2 directions or the second posterior axis M4, will The two is fixed to one another.The combination of the recessed portion of upper flange 204 and lower flange 205 forms the opening 203 corresponded on body 250 Passage, with by and step up cable 215.

For example, clamping element 200 can also include being used to grip flange guide it to the outside of grip flange Guide rail.In example as shown in Figure 4, correspond to upper flange 204 in the main body 250 of clamping element 200 and lower flange 205 is provided with edge The guide rail 207 of Longitudinal extending；After upper flange 204 is installed in main body 250, the guide rail 207 can opening from upper flange 204 Pass through and can expose in mouth 2071, it is possible thereby to guide the motion of upper flange 204 and lower flange 205 in the vertical respectively.

For example, clamping element 200 can also include corresponding to the bolt that grip flange is set, with the first posterior axis M2 or the Grip flange is positioned on two posterior axis M4.As shown in figure 4, the second bolt 210 is set corresponding to upper flange 204, it is placed through The through hole 2101 formed on the middle part boss of flange 204, so as to which upper flange 204 to be fixed on to the body 250 of clamping element 200 On.Lower flange 205 can be fixed on the body 250 of clamping element 200 in the same way.

For example, clamping element 200 corresponds to the complementation that each flange can also include being longitudinally arranged at grip flange both sides Guide rail.As shown in figure 4, one is respectively arranged with left and right sides of it corresponding to upper flange 204 on the body 250 of clamping element 200 Guide rail, i.e. left rail 208 and right rail 209, left rail 208 and right rail 209 extend in the vertical, upper flange 204 could be formed with two groove (not shown)s at its back to accommodate above-mentioned left rail 208 and right rail 209.

For example, clamping element 200 can also be included in the recessed portion for the approximate half-circular for being arranged on grip flange 204,205 Stress release tube core 212.Each stress release tube core 212 also can be correspondingly semilune shape, so as to convex corresponding to clamping Edge 204,205 can be surrounded from the cable 215 passed through between grip flange 204,205.

As shown in figure 4, stress release tube core 212 can include correspond to corresponding grip flange (upper flange 204 or under it is convex Edge 205) two ears 213 protruded in the vertical；Referring to Fig. 1 or Fig. 2, the two ears 213 can be from correspondingly from upper The opening 214 of the middle part boss both sides of flange 204 is exposed.

For fixed clamping piece 200 on connector assembly, clamping element 200 may be mounted on shielding element 7, for example, In the erecting bed of two alar parts 251 of clamping element 200, it is arranged on by the first bolt 201 and nut 202 on shielding element 7, tool For body, such as on side shield part 77.

Another embodiment of the present utility model is related to a kind of transmission line, and the transmission line is, for example, cable and/or liquid Pressure pipeline and/or Pneumatic pipe, including at least one as above any described connector assembly and have connector assembly company At least two cables connect.

In the transmission line, at least cable is connected to each other by connector assembly, and every cable passes through clamping element The pin sidepiece part or connector sidepiece part for being connected to connector assembly are clamped, when cable is torn, clamping element passes through axial side To guide rail 207 and perpendicular to axial direction guide rail 208,209 provide buffering, be applied to cable with being connected so as to weaken The stress of junction between the pin sidepiece part or connector sidepiece part of device assembly, extend the use of connector assembly and transmission line Life-span.
