- the second conductive state provides a detecting signal with respect to the cable connector 1 in which the cable 90 is inserted.
- the electrical connection state between the switch terminal 70 and the detective terminal 60 is detected as an electrical disconnection state such as the first conductive state, it is concluded that there is no electrical connection between the cable and the cable connector 1 . If the electrical connection state between the switch terminal 70 and the detective terminal 60 is detected as an electrical connection state such as the second conductive state, it is concluded that there is an electrical connection between the cable and the cable connector 1 .
- FIG. 12 which shows a cable connector in accordance with another preferred embodiment
- the difference between the previous embodiment and the embodiment is that a switch terminal 170 of the cable connector of the embodiment is fixed on a first slot 112 , and a detective terminal 160 is fixed on a second slot 113 .
- An elastic piece 140 is initially in a deformation state, and an elastic cantilever 147 is connected with a groove 125 , which maintains a pressing body 120 abutted at a first position.
- a flange 123 of the pressing body 120 is abutted against an abutting surface 175 of the switch terminal 170 to push a contact part 177 of the switch terminal 170 toward a contact end 165 of a detective terminal 160 , making the contact part 177 of the switch terminal 170 abutted against the contact end 165 of the detective terminal 160 to produce an electrical connection state.
- the electrical connection state provides a detecting signal with respect to the cable connector with no cable connected.
- a hand lever 121 of the pressing body 120 rotates along a direction 183 to overcome a force that the elastic piece 140 acts on the pressing body 120 .
- the pressing body 120 drives a deformation of the elastic piece 140 to enlarge a receiving gap 185 between the elastic piece 140 and a conductive element 150 , allowing the cable to be inserted therein.
- the elastic piece 140 rebounds and the pressing body 120 is held at a second position.
- the flange 123 of the pressing body 120 is disengaged from the abutting surface 175 of the switch terminal 170 to release a pressure that the pressing body 120 acts on the abutting surface 175 of the switch terminal 170 , allowing the elastic arm 173 to rebound along a direction 187 .
- the contact part 177 is thus separate from the contact end 165 and an electrical connection therebetween is cut off.
- the electrical connection between the switch terminal 170 and the detective terminal 160 is detectable by means of terminal detection and is appeared in the form of a detecting signal related to the cable connector in which the cable is inserted.
- the electrical connection state between the switch terminal 170 and the detective terminal 160 is detected as “electrically connected”, i.e. the first conductive state, it is concluded that there is no cable connected with the cable connector. If the electrical connection state between the switch terminal 170 and the detective terminal 160 is detected as “electrically disconnected”, i.e. the second conductive state, it is concluded that there is a cable connected with the cable connector.
- the electrical connection state between the cable connector and the cable can be determined through the detection of the electrical connection state between the switch terminal and the detective terminal.

Thehousing 10 has afirst slot 12 adjacent to aforepart 102, adetective terminal 60 fixed on thefirst slot 12, asecond slot 13 adjacent to theforepart 102, aswitch terminal 70 fixed on thesecond slot 13. Thehousing 10 further has a side opening 11 and acover plate 30 covering the side opening 11. Arear end 104 of thehousing 10 has arear opening 17, used for receiving a cable. - With reference to
FIGS. 5 to 8 , the side opening 11 of thehousing 10 is provided as an assembled opening. A middle of thehousing 10 has a raisedcolumn 14. Theconductive element 50 is arranged on the raisedcolumn 14 and fixed on thehousing 10. A rear position of thehousing 10 has apivot 15. Thepressing body 20 is arranged on thepivot 15 and rotatably connected with thehousing 10. An inner edge of theside opening 11 is arranged withbumps holes cover plate 30, so as to ensure that thecover plate 30 is fixed on thehousing 10 and theside opening 11 is entirely closed. - The
pressing body 20 includes afront part 202, arear part 204, and abody portion 29 between thefront part 202 and therear part 204. Thefront part 202 is formed with ahand lever 21. Thebody portion 29 is formed with aflange 23 which is extended laterally and abutted against theswitch terminal 70. Thebody portion 29 is further formed with agroove 25, and therear part 204 is formed with apivoting hole 27. Thepivoting hole 27 is connected with thepivot 15 of thehousing 10. Thepressing body 20 rotates between a first position and a second position relative to thehousing 10, with thepivot 15 as a center. - The
conductive element 50 includes atop 51, apositioning hole 55 formed in periphery of theconductive element 50, and anend 59 formed at abottom 57 of theconductive element 50 and extended downwardly. Thepositioning hole 55 of theconductive element 50 is sheathed on the raisedcolumn 14 of thehousing 10 so that theconductive element 50 is fixed on thehousing 10. Thetop 51 of theconductive element 50 is located inside thehousing 10. Thebottom 57 of theconductive element 50 is extended out of thehousing 10 to be connected with an external circuit board. Theconductive element 50 further includes acantilever 53, disposed at an inner side of thetop 51 of theconductive element 50. Thecantilever 53 is tilted downwardly to coordinate with theelastic piece 40 to form a receiving gap for receiving the cable. - The
elastic piece 40 includes abody part 43, abottom part 41 at bottom of thebody part 43, acutting edge 45 at top of thebody part 43. Thebottom part 41 of theelastic piece 40 is flat. Thebody part 43 is elastically deformable and is formed with thebottom part 41. Thecutting edge 45 has a thickness slightly smaller than that of thebody part 43, and coordinates with thecantilever 53 of theconductive element 50 to form the receiving gap for receiving the cable. Thecutting edge 45 is formed with anelastic cantilever 47 which is extended laterally and inserted in thegroove 25 of thepressing body 20 so that theelastic piece 40 is abutted against thepressing body 20 to be held at the first position. - The
detective terminal 60 includes atail end 61 formed at a bottom of thedetective terminal 60, amain body 63 formed in thefirst slot 12 of thehousing 10, acontact end 65 formed at a top of thedetective terminal 60, and amouth 67 formed between thecontact end 65 and themain body 63. Theswitch terminal 70 includes adistal end 71 at a bottom of theswitch terminal 70, anelastic arm 73 formed at thedistal end 71, acontact part 77 at a top of theelastic arm 73, and a abuttingsurface 75 formed between theelastic arm 73 and thecontact part 77. The abuttingsurface 75 is located at themouth 67 of thedetective terminal 60 and is abutted against theflange 23 of thepressing body 20. - An example of the
pressing body 20 of thecable connector 1 located at the first position is shown inFIG. 9 . At the first position, theelastic piece 40 contacts with theconductive element 50, and the receiving gap therebetween is entirely closed or becomes smaller than a sectional dimension of the cable, to prevent an end of the cable from entering the receiving gap. Thepressing body 20 is held at the first position by theelastic piece 40, by means of theelastic cantilever 47 of theelastic piece 40 abutting thegroove 25 of thepressing body 20. Meanwhile, theflange 23 of thepressing body 20 is abutted against the abuttingsurface 75 of theswitch terminal 70 to cause an elastic deformation of theelastic arm 73 of theswitch terminal 70, which allows theelastic arm 73 of theswitch terminal 70 to move away from thedetective terminal 60 to disconnect thecontact part 77 of theswitch terminal 70 and thecontact end 65 of thedetective terminal 60, so as to provide a disconnection between theswitch terminal 70 and thedetective terminal 60. When thepressing body 20 is at the first position, the disconnection between theswitch terminal 70 and thedetective terminal 60 is defined as a first conductive state, which is detectable by means of terminal detection, representing that thecable connector 1 is not electrically connected with the cable. - With reference to
FIGS. 10 and 11 , when thecable connector 1 is connected with the cable, thepressing body 20 rotates along arotational direction 83 to overcome a force that theelastic piece 40 acts on thepressing body 20. Theelastic piece 40 rotates along with thepressing body 20 and produces a considerable elastic deformation to open the receivinggap 85 between the cuttingedge 45 of theelastic piece 40 and the top 51 of theconductive element 50, wherein the receivinggap 85 is larger than the sectional dimension of the cable, allowing the end of thecable 90 to be inserted in the receivinggap 85. Meanwhile, thepressing body 20 is disengaged with theswitch terminal 70 by rotating along therotational direction 83 to release a pressure that thepressing body 20 acts on the abuttingsurface 75 of theswitch terminal 70, allowing theelastic arm 73 of theswitch terminal 70 to recover the elastic deformation, that is, theelastic arm 73 of theswitch terminal 70 rebounds along with adirection 87 toward thedetective terminal 60, so that thecontact part 77 of theswitch terminal 70 is abutted against thecontact end 65 of thedetective terminal 60. An electrical connection therebetween is provided. An end of thecable 90 is inserted in the receivinggap 85 of thecable connector 1 from therear opening 17 of therear end 104 of thehousing 10. Theelastic piece 40 then clamps an end of thecable 90 at between the cuttingedge 45 and thecantilever 53 by a rebounding force, whereby thecable 90 is connected with thecable connector 1. After thecable 90 is clamped in the receivinggap 85, theelastic piece 40 rebounds and thepressing body 20 is held at the second position. Thus, theflange 23 of thepressing body 20 is disengaged from the abuttingsurface 75 of theswitch terminal 70, while thecontact part 77 is abutted against thecontact end 65, representing an electrical connection. The electrical connection between theswitch terminal 70 and thedetective terminal 60 is defined as a second conductive state which is detectable by means of terminal detection. The second conductive state provides a detecting signal with respect to thecable connector 1 in which thecable 90 is inserted. - In accordance with the embodiment of the present invention, if the electrical connection state between the
switch terminal 70 and thedetective terminal 60 is detected as an electrical disconnection state such as the first conductive state, it is concluded that there is no electrical connection between the cable and thecable connector 1. If the electrical connection state between theswitch terminal 70 and thedetective terminal 60 is detected as an electrical connection state such as the second conductive state, it is concluded that there is an electrical connection between the cable and thecable connector 1. - With reference to
FIG. 12 , which shows a cable connector in accordance with another preferred embodiment, the difference between the previous embodiment and the embodiment is that aswitch terminal 170 of the cable connector of the embodiment is fixed on afirst slot 112, and adetective terminal 160 is fixed on asecond slot 113. Anelastic piece 140 is initially in a deformation state, and anelastic cantilever 147 is connected with a groove 125, which maintains apressing body 120 abutted at a first position. Aflange 123 of thepressing body 120 is abutted against an abuttingsurface 175 of theswitch terminal 170 to push acontact part 177 of theswitch terminal 170 toward acontact end 165 of adetective terminal 160, making thecontact part 177 of theswitch terminal 170 abutted against thecontact end 165 of thedetective terminal 160 to produce an electrical connection state. The electrical connection state provides a detecting signal with respect to the cable connector with no cable connected. When the cable connector is connected with a cable, ahand lever 121 of thepressing body 120 rotates along adirection 183 to overcome a force that theelastic piece 140 acts on thepressing body 120. Thepressing body 120 drives a deformation of theelastic piece 140 to enlarge a receiving gap 185 between theelastic piece 140 and aconductive element 150, allowing the cable to be inserted therein. After the cable is inserted in the receiving gap 185, theelastic piece 140 rebounds and thepressing body 120 is held at a second position. At the second position, theflange 123 of thepressing body 120 is disengaged from the abuttingsurface 175 of theswitch terminal 170 to release a pressure that thepressing body 120 acts on theabutting surface 175 of theswitch terminal 170, allowing theelastic arm 173 to rebound along adirection 187. Thecontact part 177 is thus separate from thecontact end 165 and an electrical connection therebetween is cut off. The electrical connection between theswitch terminal 170 and thedetective terminal 160 is detectable by means of terminal detection and is appeared in the form of a detecting signal related to the cable connector in which the cable is inserted. - According to the embodiment, if the electrical connection state between the
switch terminal 170 and thedetective terminal 160 is detected as “electrically connected”, i.e. the first conductive state, it is concluded that there is no cable connected with the cable connector. If the electrical connection state between theswitch terminal 170 and thedetective terminal 160 is detected as “electrically disconnected”, i.e. the second conductive state, it is concluded that there is a cable connected with the cable connector. - According to the above description with respect to the preferred embodiments of the present invention, the electrical connection state between the cable connector and the cable can be determined through the detection of the electrical connection state between the switch terminal and the detective terminal.
- It is understood that the invention may be embodied in other forms within the scope of the claims. Thus the present examples and embodiments are to be considered in all respects as illustrative, and not restrictive, of the invention defined by the claims.
