The first bus bar 20 includes a first body portion 2001 provided with a plurality of connection terminals 2003, and a connection portion 2002 extending from the first body portion 2001, wherein the connection portion 2002 is adapted to be electrically connected with the conductive pin 400.
As shown in fig. 1, the first main body portion 2001 of the first bus bar has a shape extending mainly in the second direction Y. The first main body portion of one first bus bar 20a for connection to a positive pole of a power source and the first main body portion of the other first bus bar 20b for connection to a negative pole of the power source may be stacked together. Preferably, the first main body portions of the two first bus bars 20a, 20b are separated by an insulator.

The first bus bar further includes a connection portion 2002 extending from the first main body portion 2001. In the illustrated embodiment, the connection portion 2002 extends in a first direction X and a third direction Z. In the conventional art, the connection portion of the first bus bar is electrically connected to the second bus bar extending in the first direction X and the third direction Z in a fixed manner by a screw, and therefore, there are cases in which misalignment, inclination, and the like easily occur, and the screw may be broken or the like in the case of a long-term torsional stress, mechanical shock, and the like.
In an embodiment of the present application, the connection portion 2002 of the first bus bar is adapted to be electrically connected with the conductive pin 400 of the connector 10. The conductive pin 400 is adapted to be inserted into the first hole 102 of the insulative housing to be electrically connected with the conductive terminal 200, and is slidable in the first hole 102 along the second direction Y with respect to the conductive terminal 200. In the illustrated preferred embodiment, the conductive pin 400 is in sliding electrical contact with the elastic terminal 300 of the connector 10 in the second direction Y, and the elastic terminal 300 applies a clamping force to the conductive pin 400, thereby establishing a stable electrical connection between the elastic terminal 300 and the conductive pin 400.
As shown in fig. 3, the connection portion 2002 of the first bus bar is detachably fixed to the first head of the conductive pin 400 by the first fastener 500. The first fastener 500 is a threaded fastener, preferably a screw. In this case, the first head 401 of the conductive pin 400 (shown in fig. 6) has a first threaded hole having a female thread adapted to mate with the male thread of the first threaded fastener 500. The conductive pin 400 is detachably fixed to the connection portion 2002 by screwing a first threaded fastener 500 into the connection portion 2002 and the first threaded hole, so that the conductive pin 400 is mechanically and electrically connected to the connection portion 2002.

The connector assembly further comprises two second busbars 30 which are electrically connected with the two first busbars 20 via the two connectors 10, respectively. The connecting portion 2002 of one of the first bus bars 20a and the connecting portion of the other first bus bar 20b sandwich the two connectors 10a, 10b so that the conductive pin 400 of the connector does not disengage from the connectors even though the conductive pin 400 is movably inserted therein.
In another not-shown embodiment, the first bus bar 20a and the other first bus bar 20b are separately provided, and the two connectors are also separately provided. In this case, a second threaded hole is provided at the other end of the conductive pin 400 opposite to the first head 401 to allow a second threaded fastener to be screwed therein, the second head of the second threaded fastener having a diameter larger than that of the first hole 102 passing through the insulating housing, so that the insulating housing can slide in the second direction Y along the shaft 402 between the second head of the second threaded fastener and the first head 401 of the conductive pin 400, and the conductive pin 400 does not disengage from the connector 10.
As best shown in fig. 1 to 3, the connector 10 is electrically connected to the second bus bars 30a, 30b in a movable manner in the first direction X and the third direction Z through the slot 101 at one end. The second bus bar has a contact portion 3001 adapted to be electrically connected with the conductive terminal 200 of the connector 10, the length of the contact portion 3001 in the third direction Z being greater than the length of the connector 10 in the third direction.
In one embodiment, the width W1 of the contact portion 3001 in the first direction X (as shown in fig. 1) is greater than the depth D1 of the slot 101 of the connector 10 in the first direction X (as shown in fig. 4). So that the connector 10 can move in the first direction X and/or the third direction Z with respect to the second bus bar 30 in a state where the connector 10 is electrically connected to the second bus bar 30.
In the illustrated embodiment, the second bus bar further has a second body part 3002, and the thickness of the second body part 3002 is greater than that of the contact part 3001, so that the second bus bar has sufficient rigidity not to be easily bent.
In other embodiments, the width W1 of the contact portion 3001 in the first direction X is less than or equal to the depth D1 of the slot 101 in the first direction X, or the second bus bar does not have the contact portion 3001. In this case, a concave portion 3003 communicating with the contact portion 3001 is provided in the second body portion 3002, a thickness of the concave portion 3003 in the second direction Y is equal to a thickness of the contact portion 3001, and a length in the third direction Z is larger than a length of the connector 10 in the third direction Z.

The structure of the connector 10 according to the present application is specifically described below with reference to fig. 4 to 11. FIG. 4 shows a perspective view of a connector according to the present application; FIG. 5 shows a perspective view from the rear of a connector according to the present application; FIG. 6 illustrates a cross-sectional perspective view taken along line B-B of FIG. 5 of a connector according to the present application; FIG. 7 shows a cross-sectional perspective view of the connector of FIG. 6 with the conductive pin removed;
FIG. 8 shows a perspective view of a connector according to the present application with the insulative housing removed; FIG. 9 shows a perspective view of a connector according to another embodiment of the present application with the insulative housing removed; FIG. 10 shows another perspective view of a connector according to another embodiment of the present application with the insulative housing removed; and figure 11 shows a perspective view of an insulating housing of a connector according to the present application.
As shown in fig. 1 to 11, a connector according to the present application may include an insulative housing 100, a conductive terminal 200, a conductive pin 400, and an optional elastic terminal 300 and an optional conductive block 600.
The insulating housing 100 is made of an insulating material such as plastic. As shown in fig. 11, the insulating housing includes a first hole 102 and a slot 101 at one end of the insulating housing.
The slot 101 extends in the insulating housing in the first direction X and the third direction Z and is configured to receive the second bus bar 30 inserted therein. In the illustrated embodiment, the slot 101 penetrates the insulating housing 100 in the third direction Z, so that a second bus bar 30, which is longer than the connector, can be inserted into the connector. In another embodiment, the slot 101 does not penetrate the insulating housing 100 in the third direction Z, in which case a second bus bar 30 shorter than the connector may be inserted into the connector, i.e. the length of the second bus bar 30 in the third direction Z is smaller than the length of the slot 101 of the connector in the third direction Z. In these cases, the second bus bar 30 inserted into the slot is movable in the slot 101 in the first direction X and the third direction Z.
The first aperture 102 of the insulating housing extends at least partially through the insulating housing 100 in the second direction Y. The shaft portion 402 of the conductive pin 400 of the connector (shown in fig. 6) can be inserted into the first hole 102. In the illustrated embodiment, the number of the first holes is four, but the number of the first holes may be one, two, or more, which is not limited in the present application.
In the embodiment shown, the first hole 102 of the insulating housing extends through the insulating housing so that the conductive pin 400 can be inserted from either side. In a state where the connector is assembled with the second bus bar as shown in fig. 1, two adjacent side walls of the insulating housings of two adjacent connectors are isolated by an insulator to prevent electrical contact between two opposite conductive pins 400.
Alternatively, the first hole 102 of the insulating housing penetrates one of the two sidewalls of the insulating housing without penetrating the other sidewall to prevent electrical contact between the opposite conductive pins 400.
The connector comprises a conductive terminal 200, which is arranged within the insulating housing 100 and is adapted to be movably electrically connected with the second bus bar 30, i.e. to electrically contact the second bus bar 30 inserted in the slot 101 in a manner allowing the second bus bar to be slidably inserted in the first direction X and the third direction Z relative to the conductive terminal 200.
The conductive terminal 200 is provided with a third hole 202 which is aligned with the first hole 102 of the insulative housing and the second hole 601 of the conductive block in the second direction Y, such that the conductive pin 400 is adapted to be slidably inserted into the first hole 102, the second hole 601 and the third hole 202. The number, size and position of the third holes 202 correspond to the first holes 102 of the insulation case 100.
The conductive terminal 200 further comprises a plurality of resilient arms 201, the plurality of resilient arms 201 being adapted to be slidably pressed against the second bus bar 30 inserted into the slot.
In the illustrated embodiment, the connector includes a pair of conductive terminals 200 arranged to grip opposite sides of a second bus bar inserted into the slot 101; or, opposite conductive terminals 200 are respectively disposed on inner sides of both side walls of the slot 101 of the insulative housing 100 of the connector, the opposite conductive terminals 200 slidably holding the second bus bar 30 and being electrically connectable with the second bus bar 30.
As best shown in fig. 8-10, the plurality of resilient arms of one of the pair of conductive terminals 200 are staggered with respect to the plurality of resilient arms of the other conductive terminal in the third direction Z. Further, as shown, two conductive terminals are disposed in a stacked manner along the second direction Y on each side of the conductive block 600, and the plurality of elastic arms of one of the two conductive terminals on either side of the conductive block are also staggered with respect to the plurality of elastic arms of the other conductive terminal in the third direction Z.
In another embodiment, not shown, the conductive terminal 200 is disposed on one of the two sidewalls of the slot 101 of the insulative housing 100, and the conductive terminal is not disposed on the other sidewall. In this case, the elastic arm 201 of the conductive terminal 200 slidingly clamps the second bus bar 30 together with the sidewall such that the elastic arm 201 of the conductive terminal 200 establishes electrical connection with the clamped second bus bar 30.
In a preferred embodiment, the resilient arm 201 of the conductive terminal 200 is covered with a reinforcing plate 203, so that the clamping force of the resilient arm 201 of the conductive terminal with the opposite other resilient arm or side wall to clamp the second bus bar 30 can be further reinforced.
As best shown in fig. 7 and 9, the connector further includes a resilient terminal 300 capable of conducting electricity, the resilient terminal 300 being electrically connected to the conductive terminal 200. In the illustrated embodiment, the elastic terminal 300 is disposed on a hole wall of the second hole 601 of the conductive block 600, and thus is electrically connected to the conductive block 600 and the conductive terminal 200. The conductive terminal 200 is adapted to be in sliding electrical contact with the conductive pin 400 along the second direction Y. The elastic terminal 300 has elasticity, thereby applying a clamping force to the conductive pin 400 so that the elastic terminal 300 can be brought into close contact with the rod portion 402 of the conductive pin 400 in the circumferential direction, thereby establishing a stable electrical connection.
In the illustrated preferred embodiment, the connector includes a conductive block 600, the conductive block 600 being capable of supporting the conductive terminal 200 and the resilient terminal 300. The conductive block 600 is held between the conductive terminals 200 disposed opposite to each other, and establishes a stable electrical connection with the conductive terminals 200.
The conductive block 600 may be made of a single metal plate or alloy plate, or may be made of a plurality of metal sheets laminated together. The plurality of metal sheets may be made of the same metal, for example, copper. In another embodiment, the plurality of metal sheets may be formed of different metal sheets, for example, copper sheets and aluminum sheets, which are alternately arranged, thereby reducing costs.
The length of the conductive block 600 in the third direction Z is greater than the lengths of the insulative housing 100 and the conductive terminals 200 in the third direction Z, such that at least two conductive terminals 200 are arranged on the surface of the conductive block 600 in the third direction Z.
As best shown in fig. 6, the conductive pin 400 of the connector has a first head portion 401 and a shaft portion 402. The conductive pin 400 is adapted to be connected to the connection portion 2002 of the first bus bar 20 at the first head portion 401, the first head portion 401 having a diameter larger than that of the first hole 101 of the insulating housing 100. The stem 402 is adapted to be slidably inserted into the first bore 102. The shaft portion 402 has a smooth surface so as to be able to slidingly contact with the elastic terminal 300 and establish stable electrical connection.
In the illustrated embodiment, the first head 401 of the conductive pin 400 has a threaded bore having a female thread adapted to mate with the male thread of the first threaded fastener 500. Thereby, the connection portion 2002 of the first bus bar is fixed to the first head portion 401 of the conductive pin 400 by the first threaded fastener 500, thereby establishing a stable electrical connection between the first bus bar 20 and the conductive pin 400 and between the conductive terminal 200 of the connector. In another embodiment, not shown, the connection portion 2002 of the first bus bar is fixed to the first head portion 401 of the conductive pin 400 by welding.
The length L1 of the shaft portion 402 of the conductive pin 400 in the second direction Y is greater than or equal to the thickness L2 of the connector 10 in the second direction Y. When the conductive pin 400 is inserted into the body of the connector, the shaft portion 402 of the conductive pin 400 can be brought into sufficient contact with the elastic terminal 300 to establish stable electrical connection.
In another embodiment, not shown, a second threaded hole is provided at the other end of the conductive pin 400 opposite to the first head 401 to allow a second threaded fastener to be screwed therein, the second head of the second threaded fastener having a diameter greater than the diameter of the first hole 102 through the insulating housing, so that the insulating housing can slide along the shank 402 in the second direction Y between the second head of the second threaded fastener and the first head 401 of the conductive pin 400, thereby preventing the conductive pin 400 from disengaging from the connector 10.
Connectors provided according to various embodiments of the present application are adapted to electrically connect a first bus bar 20 and a second bus bar 30. The connector comprises an insulating housing 100, the insulating housing 100 comprising a slot 101 at one end of the insulating housing and a first hole 102, the slot 101 extending in the insulating housing in a first direction X and a third direction Z and being configured to receive a second busbar 30 inserted in the slot, the first hole 102 extending at least partially through the insulating housing 100 in a second direction Y, wherein the second direction Y is perpendicular to the first direction X and the third direction Z is perpendicular to the first direction X and the second direction Y. The connector includes a conductive terminal 200, the conductive terminal 200 being disposed within the insulative housing 100 and adapted to make electrical contact with the second bus bar 30 inserted into the slot 101. The connector further includes a conductive pin 400 adapted to be inserted into the first hole 102 to be electrically connected with the conductive terminal 200, and adapted to be electrically connected with the first bus bar 20. The conductive pin 400 is slidable in the first hole 102 in the second direction Y with respect to the conductive terminal 200; and/or the conductive terminal 200 is adapted to electrically contact the second bus bar 30 inserted in the slot 101 in a manner allowing the second bus bar 30 inserted in the slot 101 to be slidable in the first direction X and the third direction Z with respect to the conductive terminal 200.
Thus, the connector 10 according to the present application is not only capable of establishing a stable electrical connection with the first bus bar 20 and the second bus bar 30, but also the connector 10 is capable of sliding relative to the first bus bar 20 in the second direction Y, so that the connector establishes a through-type floating electrical contact with the first bus bar; and the connector 10 is slidable in the first direction X and the third direction Z relative to the second busbar 30 so that the connector establishes separable, pluggable, floating electrical contact with the second busbar. Thereby eliminating the torsional stress caused by the offset mating and the oblique mating, and the problem of disconnection caused by the breakage of the screw caused by the stress.
Although a number of embodiments of the present application have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the application, the scope of which is defined in the claims and their equivalents.
