Description
TECHNICAL FIELD

The present disclosure relates to a cable connecting assembly for a machine, a contact terminal of the cable connecting assembly, and a connecting device of the cable connecting assembly.


BACKGROUND

Machines, such as off-highway trucks, wheel dozers, etc. include electric power systems or hybrid (for e.g., diesel-electric) power systems that are used to provide power for propulsion, implement movement, and other operations. Generally, such power systems include high-voltage cables for electrically connecting an electric motor (or a generator) with an inverter of the machine. A busbar is fixedly connected to a housing of the inverter. The high-voltage cables may be connected to the busbar to establish an electric connection via the high-voltage cables. Further, in order to connect the high-voltage cable with the busbar, a lug connector is crimped to the high-voltage cable. Moreover, an electrically conductive receptacle is connected between a corresponding high-voltage cable and the lug connector


In order to connect the lug connector with the busbar, openings in the lug connector and openings in the busbar align with each other for receiving one or more fastener that removably couple the lug connector with the busbar. During an assembly of the high-voltage cable, the openings in the lug connector need to be in alignment with the openings in the busbar. However, the orientation of the lug connector may be cumbersome to control, and the lug connector may have a different orientation relative to the busbar. In order to ensure accurate orientation of the lug connector, the lug connector and/or the high-voltage cable may require twisting. Typically, the high-voltage cables are stiff and large in diameter, which may make the high-voltage cables difficult to twist. Moreover, specialized tooling and/or set-ups may be required to twist the high-voltage cables in order to align the lug connector with the busbar. In some cases, attempts to twist the lug connector may damage the lug connector or the high-voltage cable, which may not be desirable.


Further, the current process of the assembly the high-voltage cables may be time consuming and may warrant considerable human effort. Moreover, assembly time may be dependent on the expertise of an assembly personnel, and novice assembly personnel may require more time to assemble as compared to experienced assembly personnel. Overall, the current design of the lug connector and the busbar as well as the process of assembling the lug connector and the busbar may be time consuming, may increase required human effort, and may be costly.


U.S. Pat. No. 8,602,829 describes a lug having an integrated shoe for fastening the lug to a conductor and a terminal of a circuit breaker. The lug includes a housing and a cavity in the housing configured to receive the electrical conductor. The shoe has a hinge connecting the shoe to an inner wall of the housing. A slot is located adjacent to the shoe such that the shoe is positioned between the cavity and the slot, which receives the terminal. A hole in the housing receives a fastener that extends into the cavity. A force applied to the fastener urges the conductor to clamp against the shoe to cause it to deflect about the hinge and to press against the terminal to hold the lug in a secure relationship relative to the terminal and to hold the conductor in a secure relationship relative to the lug.

The connecting plate 138 also defines one or more first openings 160 disposed on the second portion 142 along the longitudinal axis A1. Particularly, the first openings 160 are disposed on either side of the first curved section 148 of the connecting plate 138. In other words, the first openings 160 are disposed on the first planar surface 168 and the second planar surface 170 of the second portion 142. In the illustrated embodiment of FIG. 5, the second portion 142 defines two first openings 160. More particularly, one of the first openings 160 extends from the first planar surface 168 of the second portion 142, and the other first opening 160 extends from the second planar surface 170 of the second portion 142. In some other embodiments, the second portion 142 may define a single first opening, four first openings (two on either side of the first curved section 148), and the like.

Further, the bracket 156 defines a third planar surface 172 and a fourth planar surface 174, such that the second curved section 158 is disposed between the third planar surface 172 and the fourth planar surface 174. The bracket 156 defines a uniform thickness T2. In some examples, the thickness T2 of the bracket 156 may be similar to the thickness T1 (see FIG. 5) of the connecting device 136 (see FIG. 5). In other examples, the thickness T2 of the bracket 156 may be different from the thickness T1 of the connecting device 136.


The bracket 156 defines one or more second openings 162. Particularly, the second openings 162 are disposed on either side of the second curved section 158 of the connecting plate 138. In the illustrated embodiment of FIG. 6, the bracket 156 defines two second openings 162. More particularly, one second openings 162 extends from the third planar surface 172 of the bracket 156, and the other second opening 162 extends from the fourth planar surface 174 of the bracket 156. In some other embodiments, the bracket 156 may define a single second opening, four second openings (two on either side of the second curved section 158), and the like.


Referring now to FIG. 3, the cable connecting assembly 120 includes one or more coupling devices 164. The coupling device 164 removably connects the bracket 156 with the second portion 142 of the connecting plate 138. In some embodiments, the coupling device 164 includes a mechanical fastener. In some examples, the coupling device 164 may include a screw, a bolt, a rivet, and the like for coupling the bracket 156 to the connecting plate 138. In the illustrated example of FIG. 3, the cable connecting assembly 120 includes two coupling devices 164 herein. Alternatively, the cable connecting assembly 120 may include four coupling devices 164. Each of the first openings 160 (see FIG. 5) in the second portion 142 align with a corresponding second opening 162 (see FIG. 5) in the bracket 156 in order to receive a corresponding coupling device 164 to removably connect the bracket 156 with the connecting plate 138. The coupling devices 164 can then be tightened, drawing the bracket 156 and the second portion 142 together, securing the first body portion 126 of the cable 122 therebetween, and enabling electrical conduction.


With reference to FIGS. 3 to 6, when the bracket 156 is connected to the connecting plate 138, the first curved section 148 of the second portion 142 and the second curved section 158 of the bracket 156 together define a passage 166, such that the passage 166 at least partially receives the contact terminal 124 therein.

More particularly, the connecting device 136 of the cable connecting assembly 220 omits the intermediate portion 152 shown in FIG. 5. In this example, the first portion 140 and the second portion 142 can be integral parts of a single component.


Further, the connecting plate 138 of the cable connecting assembly 220 includes one or more first projections 268 extending along the vertical axis V1. Particularly, the second portion 142 of the connecting plate 138 includes the first projections 268.

In other embodiments, the second portion 142 may include any number of second projections 270 based on application attributes. Each second projection 270 defines a corresponding second opening 162 for receiving the corresponding coupling device 164 therein. Thus, the bracket 156 includes four second openings 16w herein, each of which will receive the corresponding coupling device 164. For removably coupling the bracket 156 with the second portion 142 of the connecting plate 138, each of the first projections 268 aligns with a corresponding second projection 270 on the second portion 142 in order to receive the coupling device 164 therein. The coupling devices 164 can then be tightened, drawing the bracket 156 and the second portion 142 together, securing the first body portion 126 of the cable 122 therebetween and enabling electrical conduction.

The third body portion 927 is axially spaced apart from the second body portion 132 by the first distance S1. The third body portion 927 defines a hollow space (not shown). The hollow space of the third body portion 927 may receive the conductive core 127 (see FIG. 9B) of the cable 122 (see FIG. 9B) therein. Further, the third body portion 927 may be crimped to secure the conductive core 127 thereto.


Referring now to FIGS. 9A and 9B, when the contact terminal 924 is connected to the connecting device 136, the first body portion 126 at least partially contacts each of the second portion 142 of the connecting plate 138 and the bracket 156 along the first distance S1. Furthermore, when the contact terminal 924 is connected to the connecting device 136, at least a portion of the second body portion 132 is received within the first slot 150 (see FIG. 5) of the second portion 142. Moreover, when the contact terminal 924 is connected to the connecting device 136, the third body portion 927 at least partially abuts the second side 146 of the second portion 142.

The second body portion 1032 is spaced apart from the first end 128 by the first distance S1. The second body portion 1032 defines a hollow space (not shown). The hollow space of the second body portion 1032 may receive the conductive core 127 (see FIG. 3) of the cable 122 (see FIG. 3) therein. Further, the second body portion 1032 may be crimped to secure the conductive core 127 thereto.


Referring now to FIG. 10B, before assembling the contact terminal 1024 with the connecting device 136 (see FIG. 10B), a section 1074 of the first body portion 126 between cut-outs 1076, 1078 may be compressed, such that the section 1074 defines a channel 1080.


Referring now to FIGS. 10A, 10B, and 10C, when the contact terminal 1024 is connected to the connecting device 136, the section 1074 of the first body portion 126 that is compressed at least partially contacts the bracket 156 along a second distance S2. Furthermore, when the contact terminal 1024 is connected to the connecting device 136, the second body portion 1032 is spaced apart from the second side 146 of the second portion 142. Moreover, as the section 1074 is compressed, the bracket 156 of the connecting device 136 is disposed and connected to the second portion 142 such that the third and fourth planar surfaces 172, 174 face the first and second planar surfaces 168, 170 of the second portion 142, and a channel 176 defined by the second curved section 158 is disposed opposite (or faces away) to the second portion 142. Further, the channel 1080 of the section 1074 receives the second curved section 158 of the bracket 156.


As can be seen from a comparison of FIG. 9B and FIG. 10C, in the former, the bracket 156 is oriented so that the second curved section 158 projects away from the second portion 142, whereas in the latter, the bracket 156 is oriented so that the channel 176 projects toward the second portion 142. In other words, the bracket 156 is flipped upside-down.

INDUSTRIAL APPLICABILITY

The present disclosure relates to the cable connecting assembly 120, 220 including the contact terminal 124, 924, 1024 and the connecting device 136. The surfaces of the contact terminal 124, 924, 1024 and the cable 122 of the cable connecting assembly 120, 220 that touch one another are generally circular, and so the cable 122 may be easily rotated relative to the connecting device 136 in order to dispose the cable 122 at a desired orientation without requiring specialized tools and set-ups. The contact terminal 124, 924, 1024 connects with the cable 122 (for example a high-voltage conductor cable) and may act as an orientation-free interface. The contact terminal 124, 924, 1024 may enable an operator to adjust the cable 122 in real-time. In examples wherein the bracket 856 includes the second slot 857, the second body portion 132 of the contact terminal 124, 924 can be received within each of the first slot 150 and the second slot 857 to ensure that the contact terminal 124, 924 is retained in position by the connecting device 136, and may prevent unintentional movement of the contact terminal 124, 924.


Further, the bracket 156, 856 may be disposed in different orientations. For example, the bracket 156, 856 may be disposed in a first orientation for connection of the contact terminal 124, 924. Moreover, the bracket 156, 856 may be disposed in a second orientation for connection of the contact terminal 1024.


Optionally, for the contact terminal 124, 924 the second body portion 132 can be received within the first slot 150 of the connecting device 136 to ensure that the contact terminal 124 is retained in position by the connecting device 136, and may prevent unintentional lengthwise (or axial) movement of the contact terminal 124, 924.


Moreover, in examples wherein the cable connecting assembly 200 includes the contact terminal 1024, the bracket 156 of the connecting device 136 may abut with the contact terminal 1024 at the cut-outs 1076, 1078 to prevent any unintentional lengthwise (or axial) movement of the contact terminal 1024.


Further, the cable connecting assembly 120, 220 may eliminate a requirement of specialized and heavy tools/set-ups for connecting the cable 122 with the inverter 121 that may otherwise damage the cable 122, the contact terminal 124, 924, 1024 or the connecting device 136 of the cable connecting assembly 120, 220. The cable connecting assembly 120, 220 may also simplify an assembly process of connecting the cable 122 with the inverter 121 while reducing assembly time and overall costs associated with the cable connecting assembly 120, 220. Further, the cable connecting assembly 120, 220 may be used across various machines. Moreover, the cable connecting assembly 120, 220 described herein may reduce human effort as the cable 122 of the cable connecting assembly 120, 220 may not have to be twisted and therefore, may reduce operator fatigue.


Overall, the cable connecting assembly 120, 220, when compared to conventional cable connecting assemblies, may be cost-effective, may eliminate the requirement of alignment between two or more components of the cable connecting assembly 120, 220, and may be retrofitted on existing machines.
