Description
- The present invention relates to connecting devices and more particularly to such a device for reliably connecting a pair of cables.
- A conventional cable connecting device is shown in
FIGS. 10, 11 and12 . It comprises amale coupling 1, afemale coupling 2, amale fastening element 3, afemale fastening element 4, a plastic shield offirst cable 5, a plastic shield ofsecond cable 6, afirst coupling 7, asecond coupling 8, and aunion 9, wherein a securing force of the innerperipheral ridges 1 b exerted on the plastic shield offirst cable 5 is vertical and not sufficient, hence, such securing is not reliable. Further, a tensile strength of the cables is not sufficient in a practical use. Likewise, a securing force between thefemale coupling 2 and the plastic shield ofsecond cable 6 is not reliable. Furthermore, the well-known cable connecting device consists of many loose parts (e.g., themale coupling 1, thefemale coupling 2, themale fastening element 3, thefemale fastening element 4, the plastic shield offirst cable 5, the plastic shield ofsecond cable 6, thefirst coupling 7, thesecond coupling 8, and the union 9) that have to be assembled by the user. Hence, it is expensive to produce and time consuming to assemble. Moreover, the prior art is not waterproof. In detail, water can penetrate through gaps between the innerperipheral ridges 1b of themale coupling 1 and the plastic shield offirst cable 5. Also, moisture generated by the penetrated water will cause short circuit or rust in themale fastening element 3. This also occurs between thefemale coupling 2 and the plastic shield ofsecond cable 6. In addition, thefirst coupling 7, thesecond coupling 8, and theunion 9 are threaded parts. Hence, they are susceptible to being disengaged from themale coupling 1 and thefemale coupling 2. That is, the securing between themale coupling 1 and thefemale coupling 2 is not reliable. This in turn deteriorates the water penetration problem as well as significantly decreases the tensile strength of the cables. Thus improvement exists. -

FIGS. 10, 11 , and12 are cross-sectional views of a conventional device for connecting cables before assembled, after assembled, and secured respectively. - Referring to
FIGS. 1 to 4 , there is shown a first preferred embodiment of a device for connecting cables constructed in accordance with the invention. The device comprises afirst cable 10, amale coupling 20, amale terminal assembly 30, asecond cable 40, afemale coupling 50, and afemale terminal assembly 60. Each of above components will now be described in detail below. - The
first cable 10 is formed by extruding process and comprises a pair ofparallel conductors shield 13 enclosed theconductors male coupling 20 comprises afirst shell 21, afirst sealing ring 22, aflange 24 in the rear end of thefirst shell 21, aspace 26 within thefirst shell 21 for passing thefirst cable 10, aprojection 23 in the forward end of thefirst shell 21, aperipheral groove 25 around theprojection 23 with thefirst sealing ring 22 fastened around, two parallel channels 27 (seeFIGS. 3 and4 ) within theprojection 23, twolengthwise apertures 270 extended from thechannels 27 into the space 26 (seeFIGS. 2A and3 ), arib 28 between thechannels 27, and a hole 280 (seeFIG. 4 ) through thefirst shell 21. - As shown in
FIG. 2A , themale terminal assembly 30 comprises two pairs ofmale terminals 31 andfirst bolts 32 both placed in thechannels 27 of thefirst shell 21. Themale terminal 31 is formed of metal and is substantially shaped as a cup. Themale terminal 31 comprises ahole 33 provided in the bottom for permitting thefirst bolt 32 to pass through, two opposite firstelastic wings 35, and two opposite secondelastic wings 37 between the firstelastic wings 35 as shown inFIG. 3 , thefirst bolts 32 are inserted through theapertures 270 to contact theconductors threads 34 secured to theshield 13 of thefirst cable 10. Thefirst cable 10 is in turn secured in thespace 26 of thefirst shell 21. Thus, an external force may be applied in the same direction as that of a tensility of the device. Also, themale terminals 31 are secured in thechannels 27. - Likewise, the
second cable 40 is formed by extruding process and comprises a pair ofparallel conductors shield 43 enclosed theconductors female coupling 50 comprises asecond shell 51, asecond sealing ring 52, aflange 54 in the rear end of thesecond shell 51, a space 56 (seeFIG. 3 ) within thesecond shell 51 for passing thesecond cable 40, arecess 53 in the forward end of thesecond shell 51, twoparallel apertures 570 extended from aninner wall 57 of therecess 53 into thespace 56, a peripheral groove 55 (seeFIG. 3 ) at a junction of therecess 53 and thewall 57 with thesecond sealing ring 52 fastened around, twoholes 510 on a top and a bottom of thesecond shell 511 respectively, aclip 58 extended from thesecond shell 51, and astud 580 near the open end of theclip 58 inserted into theholes 510 for fastening. - As seen in
FIGS. 2B and3 , thefemale terminal assembly 60 comprises a pair ofsecond bolts 61. Anelongate head 62 of thebolt 61 is formed as a contact. Thesecond bolts 61 are inserted through theapertures 570 to contact theconductors threads 64 secured to theshield 43 of thesecond cable 40. Thesecond cable 40 is in turn secured in thespace 56 of thesecond shell 51. Thus, an external force may be applied in the same direction as that of a tensility of the device. - As best seen from
FIGS. 3 and4 , in an assembly of themale coupling 20 and thefemale coupling 50, theprojection 23 of thefirst shell 21 is inserted into therecess 53 of thesecond shell 51.Heads 62 of thesecond bolts 61 are inserted through thechannels 27 of thefirst shell 21 to be fastened by theelastic wings projection 23 of thefirst shell 21 is pressed around thesecond sealing ring 52. Further, a second sealing structure is formed as inner surface of therecess 53 of thesecond shell 51 is pressed against thefirst sealing ring 22. This configuration can increase quality and prolong a useful life of the device. - Referring to
FIG. 3 specifically, it is seen that a force of theprojection 23 of thefirst shell 21 exerted on thesecond sealing ring 52 is axially. Hence, the first sealing structure is reliable. Further,first bolts 32 are driven to secure to theshield 13 of thefirst cable 10. A diameter of thethread 34 is larger than that of eitherconductor thread 34 can secure to theshield 13 so that an external force may be applied in the same direction as that of a tensility of the device. Also, theshield 13 is slightly enlarged as the insertion of thethread 34. This in turn to cause theshield 13 to tightly engage with an inner surface of thespace 26 of thefirst shell 21. Likewise, a tight engagement between thesecond bolt 61 and thespace 56 of thesecond shell 51 is effected. - Referring to
FIG. 4 specifically, thestud 580 of thefemale coupling 50 is inserted into theholes 510 of thesecond shell 51 and thehole 280 of thefirst shell 21 for securing themale coupling 20 and thefemale coupling 50 together. This in turn enhances two sealing structures. - As shown in
FIG. 3 , it is noted that theelastic wings head 62 of thesecond bolt 61 in order to secure to themale terminal 31. Further, aforward extension 36 may be formed in thethread 34 for facilitating an insertion of thefirst bolt 32 into theshield 13 of thefirst cable 10 for securing. Theextension 36 can press against theconductors forward extension 66 having the same characteristics may be formed in thethread 64. Furthermore, a sharp point may be formed in the open end of theextension 36 of thefirst bolt 32 for facilitating an insertion of thefirst bolt 32 into theshield 13 of thefirst cable 10 for securing. Such sharp point effects a more precise insertion of thefirst bolt 32 into theshield 13. Likewise, a sharp point may be formed in theextension 66 of thesecond bolt 61. Moreover, therecess 53 of thesecond shell 51 has a flat or tapered inner surface. In a case that it is a flat inner surface a firsttapered surface 531 and a continuous second tapered surface are formed within therecess 53. In brief, the second sealing structure of the invention aims at pressing the recess of thesecond shell 51 against thefirst sealing ring 22. In addition, awaterproof member 15 formed of a kind of elastic or rubber material, such as EVA foam or silicone rubber can be provided inside thespace 26. Thefirst cable 10 is urged against thewaterproof member 15 as thefirst bolt 32 is secured to theshield 13 of thefirst cable 10. Also, thewaterproof member 15 is urged against a bottom of thespace 26. This can effect a waterproofing between themale coupling 20 and thefirst cable 10.
