The outsourcing joint is generally rectangular, with a large cross-sectional area and a heavy weight. The connection point between the main body and the cover plate is offset to one side, resulting in a poor fixing effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to solve the problem that the externally-enclosed joint in the prior art is generally rectangular, has a large cross-sectional area, is heavy in weight, and the connection point between the main body and the cover plate is offset to one side, resulting in a poor fixing effect, an externally-enclosed joint for a bus is provided.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: an external connector for a busbar, comprising two connector bodies arranged opposite to each other, each connector body comprising a plug-in portion and a connecting portion extending upward from the plug-in portion, the width of the connecting portion is smaller than the width of the plug-in portion, and the two connecting portions are fixed by bolts, so that quick disassembly can be achieved, the small-width connecting portion is used to fix the two connector bodies, and the large-width plug-in portion is used for plugging the busbar, thereby increasing the contact area between the two, thereby improving the connection strength between the two, and compared with the external connector with a rectangular structure in the prior art, the cross-sectional area is reduced, thereby reducing the overall weight;

[0006] A slot for inserting the side wing of the bus is provided on one side of each plug-in part close to each other, and the notches of the two slots are opposite to each other. The bus is located between the two plug-in parts, and a rounded corner is provided at the position of each notch used to abut against the inclined surface of the side wing. The rounded corner presses against the inclined surfaces on the two wings of the bus to fix the two sections of the bus so that they are installed on the same plane. The rounded corner can reduce stress concentration and improve the stability of the abutment between the two.

[0007] The upper wall of each slot is provided with an installation slot for installing a watch strap contact finger. The extremely small heat generation power, contact resistance and stable and uniform contact force of the watch strap contact finger can ensure excellent electrical connection performance, thereby enhancing conductivity.

[0008] The above technical solution utilizes a small-width connecting part to fix the two connector bodies by bolts, and a large-width plug-in part is plugged into the bus. On the one hand, it can realize the rapid disassembly of the outsourced connector, thereby disconnecting the connection of the rigid suspension bus. On the other hand, the overall weight of the outsourced connector is lighter than that of the conventional outsourced connector, which is beneficial to reducing the overall weight of the contact network and improving the overall stability of the rigid contact network. In addition, the fillet on the slot abuts against the inclined surface of the side wing, which reduces stress concentration and improves the stability of the connection between the bus and the connector body.

[0009] Furthermore, the plug-in part and the connecting part are integrally formed, and the inner side surface of the plug-in part is coplanar with the inner side surface of the connecting part, and the outer side surface of the plug-in part protrudes from the outer side surface of the connecting part. Therefore, the length of the bolt used on the connecting part can be shortened accordingly, thereby reducing the torsional deformation of the bolt and improving the overall connection strength.

[0010] Furthermore, the installation groove is a T-shaped structure to clamp the strap contact finger, thereby improving the stability of the strap contact finger installation.

[0011] Furthermore, a gap L1 is left between the two connecting parts. Compared with the prior art, the gap is smaller. By adjusting the gap through bolts, the distance between the two connector bodies can be adjusted, thereby adjusting the clamping force on the busbar.

[0012] Furthermore, a gap L2 is left between the side wing end surface of the busbar and the bottom of the slot.

[0013] Furthermore, a gap L3 is left between the outer side surface of the busbar and the plug-in portion.

[0014] The beneficial effects of the utility model are as follows: the utility model utilizes a small-width connecting portion to fix the two joint bodies by bolts, and a large-width plug-in portion is plugged into the bus. On the one hand, the outsourced joint can be quickly disassembled to disconnect the rigid suspension bus. On the other hand, the overall weight of the outsourced joint is lighter than that of a conventional outsourced joint, which is beneficial to reducing the overall weight of the contact network and improving the overall stability of the rigid contact network. In addition, the fillet on the slot abuts against the inclined surface of the side wing, thereby reducing stress concentration and improving the stability of the connection between the bus and the joint body.

[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 4 As shown, the utility model is an externally wrapped connector for a busbar, comprising two connector bodies 1 arranged opposite to each other, each connector body 1 comprising a plug-in portion 101 and a connecting portion 102 extending upward from the plug-in portion 101, and the plug-in portion 101 and the connecting portion 102 are integrally formed;

[0028] The width of the connecting portion 102 is smaller than that of the plug-in portion 101, and the two connecting portions 102 are fixed by bolts 2, so that quick disassembly can be achieved. The small-width connecting portion 102 is used to fix the two connector bodies 1, and the inner side surface of the plug-in portion 101 is coplanar with the inner side surface of the connecting portion 102, and the outer side surface of the plug-in portion 101 protrudes from the outer side surface of the connecting portion 102. Therefore, the length of the bolt 2 used on the connecting portion 102 can be shortened accordingly, thereby reducing the twisting deformation of the bolt 2 and improving the overall connection strength. A gap L1 is left between the two connecting portions 102, and the gap is smaller than that in the prior art. By adjusting the gap through the bolt 2, the distance between the two connector bodies 1 can be adjusted, thereby adjusting the clamping force on the bus 3.

[0029] The wide plug-in portion 101 is used for plugging in the bus 3, which increases the contact area between the two, thereby improving the connection strength between the two. Compared with the rectangular structure of the outsourcing joint in the prior art, the combined structure of the connecting portion and the plug-in portion in this solution reduces the cross-sectional area, thereby reducing the overall weight.

[0030] A slot 1011 for inserting the side wing 301 of the bus 3 is provided on one side of each plug-in part 101 that is close to each other. The notches of the two slots 1011 are opposite to each other. The bus 3 is located between the two plug-in parts 101. Each notch that is used to abut against the inclined surface 3011 of the side wing 301 is provided with a rounded corner 1012. The rounded corner 1012 supports the inclined surfaces 3011 on the two wings of the bus 3 to fix the two sections of the bus 3 so that they are installed on the same plane. The rounded corner 1012 can reduce stress concentration and improve the stability of the abutment between the two. A gap L2 is left between the end face of the side wing 301 of the bus 3 and the bottom of the slot 1011, and a gap L3 is left between the outer side surface of the bus 3 and the plug-in part 101.

[0031] The upper wall of each slot 1011 is provided with an installation slot 1013 for installing a watch strap contact. The extremely small heat generation power, contact resistance and stable and uniform contact force of the watch strap contact can ensure excellent electrical connection performance, thereby enhancing conductivity. The installation slot 1013 is a T-shaped structure for placing the watch strap contact.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
