Definitions
- the present invention relates to an elastic connection terminal for an interruption device or electrical junction, the terminal comprising a conductive part provided with a end of a bearing surface for an elastic loop intended to tighten at least one cable.
- an elastic loop having a supporting branch, a clamping branch and a curved part connecting the branches support and clamping.
- the support branch is applied to the front of the support area to make contact with the conductive part, while the clamping branch is provided with a window arranged to allow the jamming of a cable introduced by an opening of a housing or cover of the device. More precisely, the cable is trapped between a movable edge of the window and a connection region located on the back of the support surface. ; the cable is loosened by pressure exerted on the curved part of the loop by means of an interconnection tool or pin.
- Such a terminal described in document EP 1 052 729, comprises an auxiliary part which serves to limit the bending of the loop and which is capable of forming a stop for the cable.
- the introduction cable in this terminal is carried out with a guide which can be improved. Else apart, the forces of the cable on insertion result in a floating of the auxiliary part, or even the risk of it breaking.
- the object of the invention is to improve in a terminal of the type described the guidance, the maintenance and cable insulation, while ensuring satisfactory resistance of the elastic loop and good cohesion of the assembly of its component parts.
- the auxiliary part is attached to the back of the support surface and present at the less a hooking element engaged with the support surface, for example in its region of connection.
- the auxiliary part preferably offers cheeks for guiding and isolating the cable, these cheeks extending to the vicinity of the connection region of the conductive part and having a guide slope adapted to the curved shape of the clamping branch of the loop.
- the hooking elements may be studs provided at the ends of the guide cheeks which are located towards the tightening branch of the elastic loop.
- the conductive part with a slot and the foot of the auxiliary part a tongue, the tongue crossing the slot to project from the side of the front of the support range.
- the tongue thus determines a range of guard or stop which limits the sliding of the loop.
- the tongue can also be provided with a snap-in element or analog which contributes to maintain the auxiliary part assembled to the conductive part.
- a protective part independent of the auxiliary part can advantageously be accommodated in the loop, being arranged in a manner known per se to limit the bending of the loop.
- Figure 1 shows schematically in side view a terminal according to the invention.
- Figure 2 is a similar view showing the elastic loop in the released position.
- Figure 3 shows in perspective before a terminal according to the invention.
- Figure 4 is a partial view of a double terminal, similar to that of Figure 3, in perspective back.
- FIG. 5 shows in perspective the auxiliary part of the terminal of FIG. 4.
- the elastic connection terminal 10 illustrated in the figures is associated or integrated with a interruption device or electrical junction device 11 such as a contactor, circuit breaker, terminal block, terminal block, or other similar electrical device involving connection fast.
- Terminal 10 is placed in a suitable housing 12 in the body or case 13 of the device.
- the terminal comprises an elastic loop 20 of known type mounted on a conductive part 14 specific to the device 11, the conductive part being for example fitted or fixed in the housing 13 of the device.
- the part 14 is fixed at a range of connection 15 by a screw 15a (illustrated by its axis in figure 1), the part 14 and / or the track 15 being secured to the housing by any means.
- Housing 12 communicates with the outside of the housing 13 by an opening 16 in the form of a funnel for the introduction of a cable conductor stripped at the end, and by an opening 17 for introducing a loosening tool or a connecting lead.
- the loop 20 offers a support branch 21 and a clamping branch 22 connected to each other by a curved portion 23.
- the loop 20 is disposed on a fixed bearing surface 18 of the conductive part 14 which offers a front 18a and a back 18b.
- the support branch 21 is applied to the front 18a
- the clamping branch 22 is provided with a window 24 defined laterally by two segments 25 and, towards the free end of the branch 22, by an end tab 26 in order to present opposite edge 18b an edge 27 tightening (see figure 3).
- auxiliary part 30 suitable for guiding, abutment and cable isolation functions, is applied against the back 18b of the support surface 18.
- the auxiliary part 30 has cable guide cheeks 31, a stop bottom 32 for the cable and a rear wall 33. It also has upward, projecting forward, studs 34 or the like hooking which engage on the conductive part 14, as well as at least down a tongue 35 penetrating into a slot 19 of the part 18. The tenons and the tongue position and hold the auxiliary part 30 on the part 14.
- the tongue 35 serves as a stop low for the elastic loop, and is provided with a latching (or interlocking) element 36 which keeps the part 30 assembled to the support surface 18.
- stops 38 in the form of ribs or fingers, cooperating with a face 12b of the housing 12. It will be observed that the cheeks 31 spare with the bottom 32 and the rear wall 33 an individualized housing 37 for the stripped end of the cable, ensuring especially the interphase guidance and isolation functions when several wires are connected in neighboring terminals corresponding to different phases (see par example Figures 4 and 5). This space also protects the electrical terminal against effects annoying due to the introduction of pollutants.
- the cheeks 31 of the auxiliary part 30 are applied by rectilinear faces to the face corresponding plane of the back 18b of the part 14 to the vicinity of the clamping branch 22 of the loop. They include just below this branch 22 ( Figures 1-4) hooking or snap-fastening elements. In this case, these are latching studs 34 engaged in 18d notches located at the top of room 14, near from the end of the support surface 18 in its connection region 18c. Cooperating elements differently shaped, but having the same hooking or snap-fastening function, can of course be substituted for studs 34 and notches 18d.
- the cheeks 31 have a shape, for example with a falling slope, adapted the sloping or curved shape of the branch 22 and its pivoting movement, to facilitate guidance.
- the tongue 35 extends orthogonally to the direction of introduction of the cable and crosses the slot 19 provided in the region 18e of the range 18 which is opposite to its region of connection 18c (see figure 4).
- the housing 37 determined by the bottom 32, the cheeks 31 and the wall 33 serves to guide the end of the cable as soon as it comes out of the funnel and house the end of the cable.
- the interlocking element or snap-fastening 36 ensures with the studs 34 a rigid and resistant assembly of the auxiliary part 30 with the conductive part 14. It will be noted that a protective part 40, independent of the auxiliary part 30, is arranged inside the loop to limit overwriting it.
- the terminal described is used as follows.
- An operating tool or spindle is engaged in the opening 17 to press the upper surface of the curved part 23 and thus put the elastic loop in the released position (in solid lines in Figure 2).
- the edges of the tongue 26 and the lateral segments 25 of the clamping branch 22 slide on the slopes of the guide cheeks 31.
- a cable for example multi-strand is then presented in front the opening 16 and engaged therein, the slope of the funnel bringing the stripped end of the cable against the back 18b of the support pad 18, in its connection region 18c.
- the end of the cable is guided on the one hand by the back 18b of the track 18, on the other hand laterally by the cheeks 31, until being stopped by the bottom 32.
- the cable inserted into its housing 37 remains isolated from a cable inserted in an adjacent housing 37 by an intermediate cheek 31 forming a partition.
- the thrust forces undergone by the auxiliary part 30 at the introduction of the cable are taken up in high by the upper part (in the figures) of the part 14 by means of the pins 34 engaged in the notches 18d and at the bottom by the tongue 35 cooperating with the slot 19.
- the tangential thrust forces undergone by the part 14, when the tool introduced into the opening 17 press the part 23 of the loop 20, are taken up by the housing 13, on the one hand by means a slot 12a which houses the end tab 14a of the part 14, on the other hand by means of the face 12b of the housing 12 against which the stops 38 of the part 30 apply.
