BACKGROUND OF THE INVENTION

scope of the invention

The present invention relates to a clamping unit, in particular to a clamping unit that can be opened by turning and a connection device with the same. Such clamping units are known to those skilled in the art, for example from DE 10 2008 060 282 A1 , the DE 10 2008 060 283 B4 , the DE 20 2018 102 026 U1 and the DE 10 2012 110 759 B4 known.

Description of the Related Art

A conventional clamping unit is mainly used to enable a conductive element inserted by a user to be clamped to an existing conductive clip in order to be electrically conductive.

The conventional clamping unit includes a clamping spring and an opening button. The conductive clip is in contact with the clip spring. The clamping spring has a tongue piece. The opening button is arranged in the longitudinal direction on the clamping spring. When inserting the conductive element, the clamping unit serves to clamp the conductive element and the conductive clip so that they are electrically conductive.

However, the clamp spring and the open button of the conventional clamp unit are arranged individually, and a movement displacement path of the tongue piece, which is pushed by the open button to open, is a linear path different from a passive displacement path of the tongue piece itself, so that the stability of the open button , which is shifted with respect to the clamping spring, is bad.

In addition, the opening button is used to drive the tongue piece to slide between two brackets, so the two brackets can be close to each other without limitation and an operation of inserting or removing the conductive member would be disturbed, causing a problem that the conductive element is difficult or impossible to insert or remove.

DETAILED DESCRIPTION OF THE INVENTION

A preferred embodiment of the present invention will be described with reference to the drawings.

Referring to 1 a twist-open clamp unit and a connector device including the same are disclosed in the present invention. The connecting device includes a housing 800 and at least one clamping unit 100 arranged in the housing 800. According to this embodiment, there are one or more of the clamping units 100 adopted in the present invention. The clamping unit 100 is for clamping a conductive element C (as in 7 shown) which is electrically connected to a conductive clamp T. The clamping unit 100 contains an elastic element 1 and an element 2 that can be opened by turning.

Referring to 1 until 6 For example, the elastic member 1 basically comprises a movable elastic arm 13, an inclined link arm 12, and a pivot link space 15 formed by a bending process. Preferably, the elastic member 1 further includes a main body 11 and a bending portion 14 .

The main body 11 can be formed into an L-shaped member as shown in the figures. The inclined connecting arm 12 is connected to one end of the main body 11; the bending part 14 is connected between another end of the main body 11 and the movable elastic arm 13, and the pivot connection space 15 is defined as a space formed by the bending part 14 subjected to the bending process so that the movable elastic arm 13 opposes the main body 11 is elastically displaceable, with the bending part 14 serving as an axis. As in 4 shown, the conductive clip T is leaning against the inclined link arm 12; and essentially, the conductive terminal T is elastically clamped between the movable elastic arm 13 and the inclined connecting arm 12 via an elastic force provided by the movable elastic arm 13 .

How out 1 until 6 As can be seen, the turn-openable element 2 comprises an opening main body 21 and at least one arm 22 protruding from the opening main body 21 . According to this embodiment, there are one or more of the arms 22 contemplated by the present invention, and it is worth noting that the scope of the present invention is not limited by the height of the arms 22. In this embodiment there are two arms 22 which are oppositely arranged at an interval which has been adopted in the present invention for the sake of clear disclosure.

A passive opening part 211 is formed at an upper end of the opening main body 21 . The structure of the passive opening part 211 is not specified according to the present invention; In this embodiment, a screwdriver groove as shown in the figures is used for clear disclosure, so that a user with a hand tool such as a screwdriver can be inserted into the passive opening part 211 to operate the twist-open element 2 make possible.

One end of the arm 22 is connected to a side defined at a lower portion of the opening main body 21, another end thereof is extended in a direction away from the opening main body 21 and is formed with a distal end 221, and the distal end 221 of the arm 22 can protrude into the pivot connection space 15 so that the distal end 221 is pivotable with the pivot connection space 15 .

How out 6 until 8th As can be seen, when the passive opening part 211 of the twist-open element 2 is pushed and rotated by the user, the twist-open element 2 can be rotated relative to the elastic element 1 with the distal end 221 serving as an axis, so that the rotary-open element 2 in a rotating state can drive the movable elastic arm 13 to slide relative to the inclined connecting arm 12 to complete an opening operation, and the conductive element C can be elastically connected between the movable elastic arm 13 and the conductive terminal T (as in 7 shown), or the conductive element C can be separated from the mobile elastic arm 13 and the conductive terminal T (as in Fig 8th shown) to be solved. Of course, when inserting the conductive member C, the loading operation can be performed without pushing the rotary openable member 2 since the conductive member C itself is capable of displacing the movable elastic arm 13 during the loading operation.

How out 2 until 4 As can be seen, the arm 22 basically comprises a first segment 22a and a second segment 22b formed in a state of the upper end of the first segment 22a being connected to the rear end of the second segment 22b or vice versa. The opening main body 21 and the second segment 22b are connected upright to two ends of the first segment 22a (including vertically connected or cross-connected at various angles), and the opening main body 21 and the second segment 22b are on the same side of the first segment 22a arranged so that the turn-openable element 2 when viewed from a side angle (as in 4 shown) is formed in a U-shape. As in 4 As shown, the first segment 22a is extended transversely from one side of the longitudinally arranged opening main body 21, and the second segment 22b is inclinedly connected to the first segment 22a.

Preferably, the movable elastic arm 13 further has a driven part 131, according to this embodiment, there are another plurality of the driven parts 131 adopted in the present invention; in this embodiment there are two driven parts 131, used for clarity of disclosure. The driven parts 131 can be formed as a tab and led out from two opposite sides of the movable elastic arm 13 . The driven part 131 is pushed and connected to the rotary opener 2, whereby the rotary opener 2 can be supported by the driven part 131, and the driven part 131 can be driven while the rotary opener 2 is rotated to allow the movable elastic arm 13 to be displaced relative to the elastic member 1.

In addition, the arm 22 further has a driving part 223, the driving part 223 is located between the passive opening part 211 and the extensible distal end 221, so that the twist-opening element 2 is supported by the driven part 131 of the movable elastic arm 13 which is pressed and connected to the driving part 223 .

The arms 22 are arranged so that they both cross the movable elastic arm 13 (as in Fig 4 shown), and the extensible arms 22 are respectively used for clamping two opposite sides of the movable elastic arm 13, i.e. the width of the movable elastic arm 13 is limited between the extensible arms 22, thereby preventing the extensible arms 22 from being close to each other lay.

As in 2 1, a convex shaft 222 penetrating into the pivot connection space 15 protrudes from the distal end 211, so that the convex shaft 222 can be pivoted coaxially with the pivot connection space 15 formed via the bending part 14. Moreover, opposite inner surfaces of the convex shafts 222 are formed with a trimmed lead angle 2221 so that the convex shaft 222 can be guided and supported to protrude into the pivot connection space 15 via the trimmed lead angle 2221 .

As in 1 , 4 , 5 and 6 As shown, the connection device according to this embodiment includes the housing 800 and the plurality of clamping units 100 arranged in the housing 800.

The case 800 includes a base 9 and a cover member 8 covering the base 9 . The cover member 8 is formed with a plurality of insertion holes 81 and a plurality of openings 82 .

The elastic member 1 of the clamp unit 100 is fixed to the base 9, the main body 11 of the elastic member 1 is preferably provided with an insertion arm 16 so that the elastic member 1 can be fixed in the case 800 by the insertion arm 16 inserted in the base 9 . The conductive clip T is also inserted into the base 9.

The distal end 221 of the turn-opening member 2 protrudes into the pivot connection space 15 of the elastic member 1 to be pivotable with the pivot connection space 15; the turn-openable element 2 is supported by the driven part 131 of the movable elastic arm 13, which is pressed and connected to the driving part 223; and the expanding arms of the twist-opening member 2 are prevented from being close to each other due to the width limitation of the movable elastic arm 13 of the elastic member 1.

In use, the conductive element C is inserted or removed between the arms of the rotary opening element 2 via the insertion opening 81 . When the movable elastic arm 13 of the elastic element 1 is to be opened, a hand tool such as a screwdriver is used to insert it into the passive opening part 211 via the opening 82 in order to rotate the to allow element 2 to be opened by turning.

Referring to 9 another type of twist-opening element 2 is disclosed, the configuration of the other type of twist-opening element 2 is basically the same as the above-mentioned twist-opening element 2, and the difference between the two is the amount of passive Opening part 211 and the structure of the convex shaft 222. The details are shown as follows. As in 9 As shown, an upper end of the opening main body 21 of the other type of the twist-open element 2 is formed with two or more of the passive opening parts 211 to be used in the various cases 800 with different model numbers (or manufactured by different companies). , in other words, the passive opening part 211 can be exposed in the opening 82 of the case 800 formed in another state; moreover, there is a convex shaft 222 pivotable in the pivot connection space 15 divided by the extended distal ends 221 so that the convex shaft 222 is pivotable coaxially with the pivot connection space 15 formed via the bending part 14 .

Based on what has been disclosed above, the advantages achieved by the present invention are as follows: The distal end 221 of the arm 22 of the rotary openable member 2 is coaxially pivotable in the pivot connection space 15 of the elastic member 1 so that the movable elastic Arm 13 can be driven to open with respect to inclined link arm 12 while rotating openable member 2 with a means for opening via rotations, and elastic member 1 and rotary openable member 2 are pivoted together instead to be arranged singly (a rotational driving path of the rotary openable member 2 may be the same as a passive displacement path of the movable elastic arm 13), so that the rotary openable member 2 is provided with better stability while rotating relative to the elastic member 1 is rotated. In addition, the twist-open panel 2 can be supported by pressing the driven part 131 of the movable elastic arm 13 and connected to the driving part 223, thereby achieving better stability.

In addition, there are other advantages of the present invention: The arms 22 of the twist-open element 2 are arranged crosswise with the movable elastic arm 13, so that the arms 22 are not close to each other due to the width limitation of the movable elastic arm 13 and a space formed between the arms for inserting or removing the conductive member C is prevented from being reduced, so that the operation of inserting or removing the conductive member C is not impaired. In addition, a lower edge of the arm 22 can be arranged to be adjacent to a thick side (not shown in the figures) of the driven part 13, thereby further enhancing the stability effect.
