Referring to fig. 1 and 2, in some embodiments, the two elastic clamping plates 14 are flush with the first side wall 13, so that the size of the leakage module can be reduced, the requirement for installation space can be reduced, and the assembly of the leakage module with other electrical components can be facilitated.

In some embodiments, the first side wall 13 and the two elastic clamping plates 14 are integrally formed, so that the processing process of the leakage module in the embodiment of the present application can be simpler, the cost can be saved, and the leakage module in the embodiment of the present application can also be more beautiful.

Referring to fig. 1, 3 and 4, in order to facilitate the insertion of the busbar, the elastic ends of the two elastic clamping plates 14 are provided with guide inclined planes 17, and the guide inclined planes 17 are located at the outer sides of the elastic ends, so that when the busbar is inserted, the busbar pins 31 can gradually enter the insertion ports 15 along the guide inclined planes 17, and the insertion is smoother.

With continued reference to fig. 4 and 5, in order to increase the elastic force of the elastic clamping plates 14, in some embodiments, the fixing ends of the two elastic clamping plates 14 are respectively provided with a groove 16 parallel to the insertion port 15, and the grooves 16 penetrate through two sides of the fixing end of the elastic clamping plate 14 in a direction parallel to the insertion port 15, so that the fixing end of the elastic clamping plate 14 is thinner and more elastic, the bus bar pins 31 are more conveniently inserted, and the elastic clamping plates 14 are not easily damaged, thereby prolonging the service life of the leakage module 1.

When the embodiment is adopted in which the fixed ends of the two elastic clamping plates 14 are both provided with the grooves 16 parallel to the insertion ports 15, in some embodiments, the cross section of the wall surfaces of the grooves 16 is circular arc-shaped, so that stress concentration is not generated, and thus the performance of the elastic clamping plates 14 can be improved.

In other embodiments, the groove 16 includes a bottom wall surface and two side wall surfaces disposed perpendicular to the bottom wall surface, whereby the area where the root of the elastic clamping plate 14 is thinnest is larger and more elastic.

With continued reference to fig. 4 and 5, since there are other terminals in the casing 10 of the module 1, in order to prevent the bus bar pin 31 in the module 1 from contacting with other terminals, in some embodiments, a bus bar pin isolation cavity 18 opposite to the socket 15 is further provided in the casing 10 of the module, so that the bus bar pin 31 can be isolated from other terminals, thereby preventing the module from short circuit.

The busbar pin isolation cavity 18 has various structures, referring to fig. 4, in some embodiments, a plurality of ribs 19 are arranged in the housing 10, the plurality of ribs 19 and the two elastic clamping plates 14 enclose the busbar pin isolation cavity 18, and the housing 10, the two elastic clamping plates 14 and the plurality of ribs 19 are integrally formed, so that the space of the busbar pin isolation cavity 18 is larger, and the processing technology is simpler.

In other embodiments, the housing 10 is provided with circular arc-shaped ribs, and the housing 10, the circular arc-shaped ribs and the two elastic clamping plates 14 define the busbar pin isolation cavity 18, so that the circular arc-shaped ribs require a smaller installation space, and the structure of the leakage module can be more compact.

Since the housing 10 is generally an injection molded part, referring to fig. 2, for the convenience of processing, in some embodiments, the housing 10 is a separate part and includes a first housing 11 and a second housing 12 that are fastened to each other along the length direction of the socket 15, it should be noted that the length direction of the socket 15 is the horizontal direction in the drawing, and the width direction is the vertical direction, a part of the elastic clamping plate 14 is located on the first housing 11, and another part of the elastic clamping plate 14 is located on the second housing 12.

Referring to fig. 4, it should be noted that, when the housing 10 is a split piece, the plurality of ribs 19 in the housing 10 are also divided into two parts, one of which is located on the first housing 11, and the other of which is located on the second housing 12, in order to facilitate alignment, a protrusion may be disposed on a part of the ribs 19 facing the socket 15 and located on the second housing 12, and a groove adapted to the protrusion may be disposed on the other part of the ribs 19 facing the socket 15, so that when the first housing 11 and the second housing 12 are assembled, the protrusion and the groove may be inserted in a matching manner, so as to facilitate alignment of the first housing 11 and the second housing 12.

In other embodiments, the housing 10 may be a single piece, i.e. integrally injection molded, so that the leakage module 1 is more attractive.

Referring to fig. 5, the position of the elastic clamping plate 14 is shown in dotted lines before the bus bar pin 31 is inserted into the bus bar pin isolating chamber 18, the position of the elastic clamping plate is shown in solid lines after the bus bar pin 31 is inserted into the bus bar pin isolating chamber 18, the position relationship between the elastic clamping plate 14 and the bus bar pin 31 requires that an inserting force is applied to the direction of the bus bar pin isolating cavity 18 when the bus bar pin 31 is inserted, when the insertion force pushes the elastic clamping plate 14 to a predetermined position, the bus bar pins 31 are completely inserted, therefore, when the width of the socket 15 is too wide, the bus bar pins 31 may not be tightly inserted, and when the width of the socket 15 is too narrow, the bus bar pins 31 may be inserted with a large insertion force, and therefore, in some embodiments, the width of the socket 15 is 0.6 to 0.7 times the thickness of the bus bar pin 31, this size range can ensure that the insertion force is not too large, and the bus bar pin 31 can be tightly inserted.

Referring to fig. 1, this application embodiment discloses an electric leakage circuit breaker simultaneously, and this electric leakage circuit breaker includes electric leakage module 1 in at least one above-mentioned embodiment and rather than a plurality of circuit breakers 2 of complex, and a plurality of circuit breakers 2 are located electric leakage module 1's both sides respectively, and wherein, circuit breaker 2 includes inlet 21, and the first lateral wall 13 of electric leakage module 1 and the lateral wall at inlet 21 place of circuit breaker 2 are located the coplanar.
