[077] The electrical terminal block 10 comprises an electrical interconnection device 85 disposed at least partially in the first inner housing 27 of the enclosure 20 and interconnecting the plurality of electrical connection terminals at a same electric potential.

[078] In other words, the electrical interconnection device 85 interconnects at a same electric potential the first electrical connection terminals 80 and the second electrical connection terminal 81.

[079] This electrical interconnection device 85 is partially visible in Figure 8, and in isolation in Figures 9 to 11.

[094] The spring leaves 100 each extend between a first fixed end 101 and a second free end 102 opposite to the first fixed end 101.

[095] The spring leaves 100 are mechanically connected and electrically interconnected each to the first portion 92 of the cage 90 of the first module 86 by the first fixed end 101.

[096] The spring leaves 100 are each provided with an actuation portion 103 and an electrical contact portion 104 at their second free end 102.

[097] The actuation portion 103 is accessible both from one of the second through holes 96 of the first module 86 and from one of the through wells 32 of the enclosure 20.

[098] The electrical contact portion 104 is configured to come against the third portion 94 of the cage 90 of the first module 86.

[099] Thus, the spring leaves 100 of the electrical interconnection device 85 and the cage 90 of the first module 86 of the electrical interconnection device 85 together form the first electrical connection terminals 80 of the electrical terminal block 10.

[100] The second module 87 of the electrical interconnection device 85 here comprises a staple 110 having an overall U-shaped cross-section. 2026202131   19 Mar 2026

[102] In the example illustrated, the electrical interconnection device 85 comprises a screw cage 115 engaged with the staple 110 of the second module 87.

[103] In particular, a portion of the screw cage 115 is clamped between the fourth portion 111 and the fifth portion 112 of the staple 110.

[104] The screw cage 115 of the second module 87 has a third inner housing 116 opening facing the second introduction opening 31 of the enclosure 20, with the third inner housing 116 which is configured to receive the second electrical cable.

[105] The screw cage 115 of the second module 87 is provided with a third through hole 117 having a first thread and which opens into the third inner housing 116 and facing the through passage 33 of the enclosure 20.

[106] Thus, the screw cage 115 of the electrical interconnection device 85 here forms the second electrical connection terminal 81 of the electrical terminal block 10.

[107] The electrical terminal block 10 comprises a plurality of first actuation members 120 movably mounted at least partially in the first inner housing 27 of the enclosure 20.

[108] The first actuation members 120 are each accessible from the fifth front face 25 of the enclosure 20, and are each configured to assume a first stable position of locking one of the first electrical cables with one of the first electrical connection terminals 80, wherein the respective first electrical cable is biased against the electrical interconnection device 85, and a first position of unlocking one of the first electrical cables with one of the first electrical connection terminals 80, wherein the associated first actuation member 120 biases the electrical interconnection device 85 to release the respective first electrical cable.

[109] In the example illustrated, the first actuation members 120 are formed by pins 121 which are each provided with a first gripping head 122 and a first rod 123 extending as a protrusion from the first gripping head 122.

[110] The first gripping head 122 of each pin 121 comprises snap lugs 124 configured to hold the first actuation member 120 in the first inner housing 27 of the enclosure 20.

[111] The first rod 123 of each pin 121 ends with a tip 125 configured to bias the actuation portion 103 of one of the spring leaves 100 of the electrical interconnection device 85.

[112] The pins 121 are each movably mounted at least partially in the first inner housing 27 of the enclosure 20, with the first gripping head 122 which is accessible from one of the 2026202131   19 Mar 2026 through wells 32 of the enclosure 20, and with the first rod 123 which is introduced at least partially into one of the second through holes 96 of the second module 87 of the electrical interconnection device 85 and which comes into contact with the actuation portion 103 of one of the spring leaves 100 of the electrical interconnection device 85.

[114] Furthermore, in the first unlocking position, the tip 125 of the first rod 123 of each pin 121 biases the actuation portion 103 of the spring leaf 100 associated with one respective of the first electrical connection terminals 80, to move the electrical contact portion 104 of the spring leaf 100 apart from the third portion 94 of the cage 90 of the second module 87, thereby releasing the respective first electrical cable.

[117] The attachment screw 131 is movably mounted in the third inner housing 116 of the screw cage 115 of the electrical interconnection device 85 by screwing the second rod 133 into the third through hole 117 of the screw cage 115, with the second gripping head 132 of the attachment screw 131 which is accessible via the through passage 33 of the enclosure 20.

[118] Thus, in the second locking position, the attachment screw 131 is further screwed into the third through hole 117 of the screw cage 115 of the electrical interconnection device 85 to bias the second electrical cable against the staple 110 of the second module 87 of the electrical interconnection device 85. 2026202131   19 Mar 2026

[119] Furthermore, in the second unlocking position, the attachment screw 131 is unscrewed in the third through hole 117 of the screw cage 115 to release the second electrical cable from the screw cage 115 of the electrical interconnection device 85.

[127] The first rigid leaf 144 is here formed as one piece with the first module 86 of the electrical interconnection device 85 and extends as a protrusion laterally from the first portion 92 of the cage 90 of the second module 87, while the second elastic leaf 145 is separate and is mechanically connected and electrically interconnected with the first portion 92 of the cage 90 of the second module 87 of the electrical interconnection device 85.

[128] The second interconnection portion 143 of the second female electrical interconnection member 141 is configured so that the second elastic leaf 145 can be moved apart and / or closer to the first rigid leaf 144 by inserting the first interconnection portion 141 of the first male electrical interconnection member 140 of another electrical terminal block of the same type. 2026202131   19 Mar 2026

[152] One of the insulating flanges 150 of the electrical terminal block 10 will be described in more detail with reference to Figures 14 and 15.

[153] The insulating flange 150 has a first side wall 151 and a second side wall 152 opposite to the first side wall 151.

[154] The insulating flange 150 has a third front wall 153 and a fourth rear wall 154 opposite to the third front wall 153, with the third front wall 153 which is configured to receive the first locking member 60 of the electrical terminal block 10, and with the fourth rear wall 154 which is configured to receive the second locking member 70 of the electrical terminal block 10.

[156] In the example illustrated, the third male mechanical fastening member 155 and the fourth female mechanical fastening member 156 each comprise third sliders 157 and fourth sliders 158, respectively, with the third sliders 157 and the fourth sliders 158 having shapes complementary respectively to the second sliders 43 of the second female mechanical fastening member 41 and to the first sliders 42 of the first male mechanical fastening member 40. 2026202131   19 Mar 2026

[157] In other words, the third sliders 157 of the third male mechanical fastening member 155 and the fourth sliders 158 of the fourth female mechanical fastening member 156 also have complementary shapes, especially herein dovetail shapes.

[158] In particular, the third sliders 157 of the third male mechanical fastening member 155 extend as a protrusion from the first side wall 151 of the insulating flange 150, while the fourth sliders 158 of the fourth female mechanical fastening member 156 extend as a protrusion from the second side wall 152 of the insulating flange 150.

[165] It will be noted that the second locking member 70 of the electrical terminal block 10 is configured to cooperate by snapping with the fourth rear wall 154 of one of the insulating flanges 150, so as to enable positional locking of the respective insulating flange 150 on the first side face 21 of the enclosure 20.

[166] It will also be noted that the first locking member 60 of the electrical terminal block 10 is further configured to cooperate by snapping with the third front wall 153 of one of the insulating flanges 150, so as to enable positional locking of the respective insulating flange on the second side face 22 of the enclosure 20.

[167] Mechanical fastening and positional locking of the insulating flanges 150 which are removably mounted to the first side face 21 and to the second side face 22 of the enclosure 20 of the electrical terminal block 10 respectively will now be described. 2026202131   19 Mar 2026

[168] In the example illustrated, that of the insulating flanges 150 which is removably mounted to the first side face 21 of the enclosure 20 is received on the enclosure 20 by sliding the third sliders 157 of the third male mechanical fastening member 155 into the second sliders 43 of the second female mechanical fastening member 41, with the third sliders 157 and the second sliders 43 cooperating by shape complementarity, so as to allow mechanical fastening of the respective insulating flange 150 to the first side face 21 of the enclosure 20.

[169] In particular, the third sliders 157 of the third male mechanical fastening member 155 and the second sliders 43 of the second female mechanical fastening member 41 slide relative to each other, until the third sliders 157 come into contact with the second sliding stop 54 and the second sliders 43 come into contact with the third sliding stop 164.

[170] Furthermore, positional locking of the insulating flange 150 which is removably mounted to the first side face 21 of the enclosure 20 is carried out by the cooperation by snapping the second locking member 70 onto the fourth rear wall 154 of the respective insulating flange 150.

[171] Thus, the insulating flange 150 which is removably mounted to the first side face 21 of the enclosure 20 covers the second female electrical interconnection member 141.

[172] In the example illustrated, the other of the insulating flanges 150 which is removably mounted to the second side face 22 of the enclosure 20 is received on the enclosure 20 by sliding the fourth sliders 158 of the fourth female mechanical fastening member 156 into the first sliders 42 of the first male mechanical fastening member 40, with the fourth sliders 158 and the first sliders 42 cooperating together by shape complementarity, so as to allow mechanical fastening of the respective insulating flange 150 to the second side face 22 of the enclosure 20.

[173] In particular, the fourth sliders 158 of the fourth female mechanical fastening member 156 and the first sliders 42 of the first male mechanical fastening member 40 slide relative to each other, until the fourth sliders 158 come into contact with the first sliding stop 48 and the first sliders 42 come into contact with the fourth sliding stop 169.

[174] Furthermore, positional locking of the insulating flange 150 which is removably mounted to the second side face 22 of the enclosure 20 is carried out by the cooperation by snapping the first locking member 60 onto the third front wall 153 of the respective insulating flange 150.

[175] Thus, the insulating flange 150 which is removably mounted to the second side face 22 of the enclosure 20 covers the first male electrical interconnection member 140.

[176] Figures 16 to 19 show in a cross-section view a series connection of several electrical terminal blocks 10 of the electrical system 1. 2026202131   19 Mar 2026

[177] As visible in Figure 16, the second electrical terminal block 12 is mechanically connected and electrically interconnected to both the first electrical terminal block 11 and the third electrical terminal block 13.

[178] The insulating flanges 150 of the second electrical terminal block 12 have been removed, while one of the insulating flanges 150 of each of the first electrical terminal block 11 and the third electrical terminal block 13 have also been removed.

[179] As visible in Figure 17, the second electrical terminal block 12 is adjoined to the first electrical terminal block 11 and is slid relative to the first electrical terminal block 11, with the first male electrical interconnection member 140 and the second female mechanical fastening member 41 of the second electrical terminal block 12 cooperating respectively with the second female electrical interconnection member 141 and the first male mechanical fastening member 40 of the first electrical terminal block 11, such that the first electrical terminal block 11 and the second electrical terminal block 12 are mechanically connected and electrically interconnected together.

[180] It will be noted that, in a similar manner, the third electrical terminal block 13 is adjoined to the second electrical terminal block 12 and is slid relative to the second electrical terminal block 12, with the first male electrical interconnection member 140 and the second female mechanical fastening member 41 of the third electrical terminal block 13 cooperating respectively with the second female electrical interconnection member 141 and the first male mechanical fastening member 40 of the second electrical terminal block 12, such that the second electrical terminal block 12 and the third electrical terminal block 13 are mechanically connected and electrically interconnected together.

[181] As is also visible in Figure 17, the second electrical terminal block 12 is positionally locked to the first electrical terminal block 11 by snapping the first locking member 60 of the first electrical terminal block 11 on the fifth front face 25 of the second electrical terminal block 12.

[182] It will be noted that, in a similar manner, the third electrical terminal block 13 is positionally locked to the second electrical terminal block 12 by snapping the first locking member 60 of the second electrical terminal block 12 on the fifth front face 25 of the third electrical terminal block 13.

[183] As visible in Figure 18, the insulating flange 150 of the first electrical terminal block 11 is removably mounted to the first side face 21 of the enclosure 20 of the first electrical terminal block 11, so as to cover the first male electrical interconnection member 140 of the first electrical terminal block 11. 2026202131   19 Mar 2026

[184] In other words, the first male electrical interconnection member 140 of the first electrical terminal block 11 is electrically insulated and protected from the external environment.

[185] In particular, the insulating flange 150 of the first electrical terminal block 11 is positionally locked by the second locking member 70 of the first electrical terminal block 11 which cooperates by snapping with the fourth rear wall 154 of the respective insulating flange 150.

[186] As visible in Figure 19, the insulating flange 150 of the third electrical terminal block 13 is removably mounted to the second side face 22 of the enclosure 20 of the third electrical terminal block 13, so as to cover the second female electrical interconnection member 141 of the third electrical terminal block 13.

[187] In other words, the second female electrical interconnection member 141 of the third electrical terminal block 13 is electrically insulated and protected from the external environment.

[188] In particular, the insulating flange 150 of the third electrical terminal block 13 is positionally locked by the first locking member 60 of the third electrical terminal block 13 which cooperates by snapping with the third front wall 153 of the respective insulating flange 150.

[189] Thus, the electrical terminal block 10 can be mechanically connected and electrically interconnected with one or more other electrical terminal blocks of the same type, in a simple and quick manner.

[190] It is sufficient to mechanically fasten, for example, the second female mechanical fastening member 41 of a first terminal block with the first male mechanical fastening member 40 of a second terminal block, to directly interconnect the first male electrical interconnection member 140 of the first terminal block with the second female electrical interconnection member 141 of the second terminal block, which first and second terminal blocks are thereby adjoined and electrically interconnected.

[191] Furthermore, in the electrical terminal block 10, the first introduction openings 30 are overall juxtaposed along the first zone 28, while the second introduction opening 31 is superimposed on the first introduction openings 30, so that the first electrical connection terminals 80 receive first electrical cables in a first mounting sense, whereas the second introduction opening 31 receives a second electrical cable in a second mounting sense opposite to the first mounting sense but which is overall in a same mounting direction.

[192] In other words, the second introduction opening 31 is not juxtaposed with the first introduction openings 30, and the first electrical cables and the second electrical cable are not electrically connected to the electrical terminal block 10 in the same mounting sense. 2026202131   19 Mar 2026

[193] Figures 20 to 23 illustrate an alternative embodiment of the electrical system 180, comprising a first plurality of distribution and / or patch electrical terminals 10 that are associated in series, and a second plurality of distribution and / or patch electrical terminals 10 that are associated in series.

[194] In the example illustrated, the electrical system 180 comprises a first electrical terminal block 181 and a second electrical terminal block 182 adjoined to the first electrical terminal block 181, with the first electrical terminal block 181 and the second electrical terminal block 182 being mechanically connected and electrically interconnected together.

[196] In particular, the second electrical terminal block 182 and the third electrical terminal block 183 are mechanically connected together via one of the insulating flanges 150 of the second electrical terminal block 182 or one of the insulating flanges 150 of the third electrical terminal block 183.

[197] It will be noted that the other insulating flanges 150 of the first electrical terminal block 181, of the second electrical terminal block 182, of the third electrical terminal block 183 and of the fourth electrical terminal block 184 have been removed.

[198] It will also be noted that the electrical system 180 comprises two mounting insulating flanges 185 each mechanically connected to one of the first electrical terminal block 181 and the fourth electrical terminal block 184.

[199] As visible in Figure 21, the insulating flange 150 is positionally locked to the second side face 22 of the enclosure 20 of the second electrical terminal block 182 by snapping the first locking member 60 of the second electrical terminal block 182 onto the third front wall 153 of the insulating flange 150.

[200] As visible in Figure 22, the insulating flange 150 is positionally locked to the first side face 21 of the enclosure 20 of the third electrical terminal block 183 by snapping the second locking member 70 of the third electrical terminal block 183 onto the fourth rear wall 154 of the insulating flange 150.

[201] Thus, the first electrical terminal block 181 and the second electrical terminal block 182 are electrically insulated from the third electrical terminal block 183 and the fourth electrical terminal block 184, while being mechanically connected together by means of the insulating flange 150. 2026202131   19 Mar 2026

[203] In other words, the fifth male mechanical fastening member 186 and the sixth female mechanical fastening member 187 of the mounting insulating flanges 185 are also complementary respectively to the fourth mechanical fastening female member 156 and the third mechanical fastening male member 155 of the insulating flanges 150.

[204] Furthermore, the mounting insulating flanges 185 each comprise herein a mounting member 188 configured to allow mechanical fastening of the electrical system 180 on a determined support.

[205] In the example illustrated, the mounting member 185 is formed by a groove 189 configured to allow mechanical fastening of the electrical system 180 on mounting rails of a chute.
