The specific embodiment

Fig. 5-23 has shown releasable in-line cable tie 30,130.Especially, Fig. 5-13 and Figure 20-23 relates to cable strapping 30, and Figure 14-19 relates to cable strapping 130.Cable strapping 30,130 is used for fixing cable harness 32,132 by suitable Unitarily molded the forming of heat of polymerization plastic material such as 6.6 nylon.Can expect that equally cable strapping 30,130 can be molded by the nylon or the non-nylon material of other grades.

As shown in Figure 5, cable strapping 30 comprises that a head 34 and is with 36.Make the necessary any length of wishing of diameter of surrounding object to be tightened with 36.Preferably as shown in figure 10, strapping 36 comprises a plurality of tooth portion 38, and described tooth portion vertically separates along strapping 36 inside faces.

Preferably as shown in Figure 6, head 34 is formed with first and

second sidewalls

40,42, end wall 44 and roof 46, and between them, define a band positioning groove 48 (see figure 7)s.Locking limit 50 is connected on the end wall 44 by pivot hinge 52, and described limit 50 has a plurality of tooth portion 54.As shown in figure 10, in the time of in being with 36 insertion grooves 48, tooth portion 54 engages with tooth portion 38 with 36.

Shown in Figure 20-23, cable strapping 30 can utilize the cable strapping tension adjustment of standard and the instrument that strapping cuts off, and for example handheld tool 56 applies.Temporarily tying up when can be used for lead or cable harness and make with 36 cuts off making assembling clean and tidy then in the end, do not have afterbody 34 outstanding from the head, preferably as shown in figure 23.

As shown in Figure 7, roof 46 or bridge cut-off parts 46 (partial bridge) 34 the first side wall 40 from the head stretch out, and have roughly covered half of groove 48.Thus, be with 36 not only to support, also partly support by bridge parts 46 by first and second sidewalls 40,42.This design allows to lift strapping 36 by hand or handheld tool 56, and releases cable strapping 30 automatically not.Shown in Figure 12 and 13, cable strapping 30 can be only by realizing unclamping along specific direction distortion strapping 36.

In the operating process, strapping 36 utilizes hand or handheld tool 56 to be fixed in the head 34, as shown in figure 20.The unnecessary strapping 36 of handheld tool 56 finishings forms cable strapping as shown in figure 23 then.Because strapping 36 is supported by first and

second sidewalls

40,42 and bridge parts 46, strapping 36 can lift with hand or hand power tool 56, and releases cable strapping 30 not.Preferably as shown in figure 12, cable strapping 30 only is with 36 just can unclamp by twisting in the counterclockwise direction.As shown in figure 13, second sidewall 42 is outwards crooked, therefore allows to be with 36 to withdraw from groove 48.Can expect that equally bridge parts 46 can extend out from second sidewall 42.In such configuration, cable strapping 30 can be with 36 to realize unclamping by the clockwise direction distortion.On either direction, cable strapping 30 can utilize handheld tool 56 to apply and can not unclamp automatically.

Figure 14-19 has shown cable strapping 130.Cable strapping 30 shown in cable strapping 130 and Fig. 5-13 and Figure 20-13 is similar, and just cable strapping 130 does not have roof or bridge cut-off parts.Therefore, cable strapping 130 has the open type top, preferably as shown in figure 16.Be with 136 can upwards lift with hand or handheld tool and 134 unclamp from the head, preferably as shown in figure 19.Upward force (along the direction of arrow) produces cross component on first and second sidewalls 140,142, cause sidewall 140,142 outwards crooked, therefore allows to be with 136 to withdraw from strapping positioning groove 148.Except can unclamp with repeated usage, cable strapping 130 also can be used as tension limiter, prevents that handheld tool from tying up the object tension.This to the matching used cable strapping of communication cable be important characteristic because tie up the reduction that tension can cause transmission performance.

Can unclamp in-line cable tie can utilize handheld tool to apply and can not unclamp automatically.Interchangeable, can unclamp in-line cable tie and can be used as tension limiter.Should be noted in the discussion above that above-mentioned graphic embodiments of the invention and preferred embodiment are not exhaustive according to the attainable form of unclamping in-line cable tie of the present invention; On the contrary, can be regarded as the present invention and understand representational, exemplary embodiment on the basis.
