Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electrically conductive connection, especially to a metal bar connector. BACKGROUND

[0002] With the rapid development of new energy vehicles, various parts used in new energy vehicles are in large quantities. The metal bar connector is a connector used for connecting the power output end of the battery. The existing metal bar connector has a similar structure to the connector disclosed in the Chinese utility model patent with the authorization announcement number CN220628313U, which includes a connector shell. The connector shell includes a cylindrical body and a threading cylinder segment arranged on the side surface of the cylindrical body. A cover is detachably installed at the top opening of the cylindrical body. A cylindrical main insulator is installed in the cylindrical body through the bottom opening. An avoidance notch is arranged on the main insulator at a position corresponding to the threading cylinder segment. A sleeve insulator is installed in the threading cylinder segment. A conductive bar for connecting with the cable is installed in the sleeve insulator. The front end of the conductive bar extends into the inner cavity of the main insulator through the avoidance notch. A bolt hole is arranged on the conductive bar. A connecting bolt passing through the conductive bar from the bolt hole can be screwed onto the conductive connection bar of the socket connector and press the conductive bar onto the conductive connection bar, realizing the conduction of the circuit.

[0003] When the cable connected to the rear end of the conductive bar of the metal bar connector bears tension, the tension is transmitted to the connecting bolt, which may cause connection failure in severe cases.

A locking key extending upward and downward is installed in the cylindrical body. The locking key passes through the clamping hole. When the cable connected to the rear end of the conductive bar bears tension, this part of the tension can be transmitted to the locking key and then to the cylindrical body by the conductive bar, reducing the force borne by the connecting bolt and ensuring the reliability of the connection. However, this method requires opening the cover and removing the locking key when disassembling the conductive bar, which is inconvenient and time-consuming. SUMMARY

DETAILED DESCRIPTION

[0022] The features and performances of the utility model are described in further detail below in combination with embodiments.

[0023] The metal bar connector of the utility model is correspondingly provided with concave-convex matching structures on the conductive bar mounting cavity and the conductive bar, and the width of the conductive bar mounting cavity is greater than the width of the conductive bar, so that when the conductive bar is installed into the conductive bar mounting cavity, the conductive bar can be obliquely inserted into the conductive bar mounting cavity at a certain angle to one side in the width direction, and the concave-convex matching structures on the conductive bar and the conductive bar mounting cavity can be staggered in the width direction, so that the conductive bar is inserted into place; when the conductive bar returns to the parallel state with the conductive bar mounting cavity, the concave-convex matching structures can be engaged, thereby realizing the anti-disengagement stop of the conductive bar and the conductive bar mounting cavity; similarly, when the conductive bar needs to be disassembled, the conductive bar is inclined to one side in the width direction to make the concave-convex matching structures disengage, and then the conductive bar can be pulled out of the conductive bar mounting cavity. Overall, the metal bar connector of the utility model can ensure the tensile strength of the conductive bar while being convenient to disassemble and assemble.

[0024] Specifically, on the basis of the above concept, the following provides a plurality of different embodiments.

[0025] In a basic embodiment, as Figures 1-3As shown, similar to the existing metal strip connector, it mainly includes a connector housing and an insulating part installed in the connector housing, and a conductive strip 6 for connecting a cable is installed in the insulating part. The connector housing includes a cylindrical body 1 and a threading cylinder segment 10 arranged on the side of the cylindrical body 1, the inner cavity of the threading cylinder segment 10 is communicated with the inner cavity of the cylindrical body 1, a sleeve insulator 5 is installed in the threading cylinder segment 10, the sleeve insulator 5 is part of the insulating part, the sleeve insulator 5 has a conductive strip mounting cavity 53, and the conductive strip 6 is mounted in the conductive strip mounting cavity 53. The rear end of the conductive strip 6 is used to connect the cable, and the front end extends into the inner cavity of the cylindrical body 1.

[0026] The cylindrical body 1 is in the form of an open upper end and an open lower end, a top cover 2 is detachably installed at the open upper end, and the open lower end is used for the mating connector to extend into the inner cavity of the cylindrical body 1 to connect the conductive strip 6. The conductive strip 6 is provided with a bolt through hole 60 which is vertically through the conductive strip 6 at the position of the front end extending into the cylindrical body 1, and when the conductive strips 6 of the mating connector and the metal strip connector of the utility model are vertically corresponding, the conductive connection of the metal strip connector and the mating connector is realized by the connecting bolt assembly 3 vertically passing through the two conductive strips 6. A top sealing ring 12 is clamped between the top cover 2 and the cylindrical body 1 to ensure the top sealing.

[0027] As the focus of the present embodiment, unlike the prior art, a concave-convex matching structure is arranged on one side edge of the conductive strip 6 in the width direction and the inner wall of the conductive strip mounting cavity 53, the width of the conductive strip mounting cavity 53 is greater than the width of the conductive strip 6, and the range that the width of the conductive strip mounting cavity 53 is greater than the width of the conductive strip 6 meets a condition, that is, the conductive strip 6 can be obliquely inserted into the conductive strip mounting cavity 53 at a certain angle in the width direction, and when the conductive strip 6 is in a parallel state with the conductive strip mounting cavity 53, the concave-convex matching structure is engaged to realize the anti-disengagement stop of the conductive strip 6 and the conductive strip mounting cavity 53 in the insertion direction of the conductive strip 6. That is, the width of the conductive strip mounting cavity 53 is slightly greater than the width of the conductive strip 6, and when the conductive strip 6 is inserted into the conductive strip mounting cavity 53 at a certain angle in the width direction (the front end of the conductive strip 6 is inclined away from the side where the concave-convex matching structure is located), the concave-convex matching structure on the conductive strip 6 and the conductive strip mounting cavity 53 can be staggered in the width direction, so that the conductive strip 6 is inserted in place, and when the conductive strip 6 returns to the parallel state with the conductive strip mounting cavity 53, the concave-convex matching structure can be engaged.

[0028] In different embodiments, the concave-convex matching structure can be a notch provided on the cavity wall of the conductive strip mounting cavity 53 and a convex part provided on the edge of the conductive strip 6, or the concave-convex matching structure can be a convex part provided on the cavity wall of the conductive strip mounting cavity 53 and a notch provided on the edge of the conductive strip 6. The shape of the convex part can be square or triangular or trapezoidal or arc-shaped, and correspondingly, the shape of the notch is adapted to the shape of the convex part. As shown in the embodiment of Figure 3 , the shape of the convex part is arc-shaped, and the shape of the notch is also arc-shaped. Since the conductive strip 6 is inserted into the conductive strip mounting cavity 53 at an inclined angle and is deflected to a parallel state with the conductive strip mounting cavity 53 after being inserted into place, the convex part and the notch are provided in an arc shape to facilitate the engagement of the concave-convex matching structure. Moreover, as shown in the embodiment of Figure 3 , the arc-shaped convex part 52 is provided on the cavity wall of the conductive strip mounting cavity 53, and the arc-shaped notch 62 is provided on the edge in the width direction of the conductive strip 6. In this way, the edge of the conductive strip 6 can be avoided from having a local convex structure, and the insertion of the conductive strip 6 into the conductive strip mounting cavity 53 can be relatively smooth. In this case, the width of the conductive strip and the conductive strip mounting cavity specifically satisfies the following conditions, that is, when the conductive strip 6 is inserted into the conductive strip mounting cavity 53 at an inclined attitude in the width direction, the edge of the conductive strip 6 opposite to the edge where the arc-shaped notch 62 is located has a first contact point with the cavity wall of the conductive strip mounting cavity 53, the edge of the conductive strip 6 where the arc-shaped notch 62 is located has a second contact point with the cavity wall of the conductive strip mounting cavity 53, the first contact point is located in front of the second contact point, the distance between the front edge of the arc-shaped notch 62 and the farther side cavity wall of the conductive strip mounting cavity 53 is smaller than the distance between the arc-shaped convex part 52 and the other side cavity wall of the conductive strip mounting cavity 53, and the distance between the arc-shaped convex part 52 and the other side cavity wall of the conductive strip mounting cavity 53 is smaller than the distance between the front edge of the arc-shaped notch 62 and the other side edge of the conductive strip. Thus, it can be achieved that after the conductive strip is inserted into the conductive strip mounting cavity at an inclined angle and is restored to a parallel attitude with the conductive strip mounting cavity, the arc-shaped notch and the arc-shaped convex part can remain engaged and will not be directly pulled out when subjected to a rearward force.

[0029] In an embodiment, the conductive strip 6 is in a rectangular strip structure, that is, the front end and the two side edges are all perpendicular to each other. In this case, in order to adapt to the deflection of the conductive strip 6 in the conductive strip mounting cavity 53, the length of the conductive strip mounting cavity 53 is greater than the length of the conductive strip 6, or in other words, when the conductive strip 6 is installed to a predetermined position in the conductive strip mounting cavity 53, there is still a deflection space in front of the conductive strip 6 in the conductive strip mounting cavity 53. As shown in the embodiment of Figure 3 , the front end surface of the conductive strip 6 and the side surface of the conductive strip 6 where the concave-convex matching structure is provided are connected by a circular arc profile surface 61. In this way, when the conductive strip 6 is deflected relative to the conductive strip mounting cavity 53, the space occupied by the deflection can be reduced, which is conducive to the miniaturization of the sleeve insulator 5.

[0030] In one embodiment, the bolt hole 60 on the conductive busbar 6 is a circular hole, the diameter of which is adapted to the diameter of the connecting bolt assembly 3; or, the diameter of the circular hole is larger than the diameter of the connecting bolt in the connecting bolt assembly 3. In a more preferred embodiment, the bolt hole 60 on the conductive busbar 6 is a unicornuate hole, which extends along the length of the conductive busbar 6. This reduces the installation accuracy of the conductive busbar 6 in the conductive busbar mounting cavity 53, facilitating the connection between the metal busbar connector and the adapter connector. Furthermore, by rationally designing the size of the unicornuate hole and the position of the convex-concave mating structure, when the conductive busbar 6 is pulled by the cable connected to the rear end, the pulling force is only borne by the convex-concave mating structure, that is, the pulling force is transferred to the connector housing and not to the connecting bolt assembly 3, thus ensuring the reliability of the conductive connection.

[0031] In different embodiments, the location of the convex-concave mating structure can be different. For example, in one embodiment, two conductive bars 6 are arranged in parallel, and the convex-concave mating structure is located on the edge of the conductive bar 6 in the width direction opposite to that of the other conductive bar 6. Or in another embodiment, such as... Figure 3 As shown, the concave-convex mating structure is provided on the edge of the conductive bus 6 in the width direction that is close to another conductive bus 6.

[0032] Based on the above embodiments, in a more specific embodiment, such as Figures 1-4 As shown, the opening of the threading section 10 is equipped with a sealing structure, specifically including an elastic sealing body 7 and a sealing cap 8. The elastic sealing body 7 is made of a soft, elastic material such as rubber, and has two through holes for the conductive busbars 6 to pass through. When the conductive busbars 6 pass through the through holes, they are held tightly by the hole walls to achieve a seal. The sealing cap 8 is used to fasten onto the threading section 10 and seal the elastic sealing body 7 inside the threading section 10. The elastic sealing body 7 has a certain thickness, which allows the hole walls of the through holes to have a certain straightening effect on the conductive busbars 6. It is this straightening effect that ensures that the two conductive busbars 6 are in a parallel state, and that the conductive busbars 6 and the conductive busbar mounting cavity 53 are in a parallel state. In other words, during the process of inserting the conductive busbar 6 into the conductive busbar mounting cavity 53 at an angle, the rear end of the conductive busbar 6 exerts a certain force on the elastic sealing body 7, causing it to deform. After the conductive busbar 6 is inserted into the conductive busbar mounting cavity 53, the elastic sealing body 7 restores its deformation to straighten the conductive busbar 6 and restore it to a state parallel to the conductive busbar mounting cavity 53, that is, the state of interlocking of the concave and convex mating structure.

[0033] In order to ensure the installation reliability of the elastic sealing body 7 in the threading cylinder segment 10, in a more specific embodiment, the sleeve insulation body 5 is provided with a forward blocking outer step 51, the threading cylinder segment 10 is provided with a backward blocking inner step 15, and the sealing tail cover 8 is buckled to the outer surface of the threading cylinder segment 10 and presses the elastic sealing body 7 against the rear end surface of the sleeve insulation body 5, so as to realize the installation of the elastic sealing body 7 and the sleeve insulation body 5 in the threading cylinder segment 10. In other embodiments, the sleeve insulation body 5 can be fixedly installed in the threading cylinder segment 10 through a buckling structure or a forced installation structure, and the elastic sealing body 7 is clamped between the rear end of the sleeve insulation body 5 and the sealing tail cover 8.

[0034] On the basis of the above-mentioned embodiments, in the embodiment shown in Figures 2-3 , when the sleeve insulation body 5 is installed in the threading cylinder segment 10, the front end extends into the inner cavity of the cylindrical main body 1, and the front end of the sleeve insulation body 5 is provided with a bolt avoiding hole 50 corresponding to the bolt through hole 60 at the upper side of the conductive row 6, so as to allow the connecting bolt assembly 3 to pass from top to bottom. The lower side of the conductive row 6 is exposed from the lower side of the sleeve insulation body 5 as a whole, so as to be attached to the conductive row 6 of the adapter connector.

[0035] On the basis of the above-mentioned embodiments, in a more preferred embodiment shown in Figures 2-3 , the insulation component further comprises an inner insulation body 4 installed in the cylindrical main body 1, the inner insulation body 4 is in a tubular structure with a blocked upper end, the side surface of the inner insulation body 4 is provided with an avoiding gap for the front end of the sleeve insulation body 5 to extend into, and the blocked upper end of the inner insulation body 4 is provided with a connecting avoiding hole 40 at a position corresponding to the bolt avoiding hole 50 of the sleeve insulation body 5, so as to allow the connecting bolt assembly 3 to pass from top to bottom. A bottom sealing ring 14 is installed at the lower end of the cylindrical main body 1, so as to ensure the sealing of the connecting part after being connected to the adapter connector. The arrangement of the inner insulation body 4 improves the insulation reliability between the conductive row 6 and the cylindrical main body 1.

[0036] On the basis of the above-mentioned embodiments, in a more preferred embodiment, the bolt connecting assembly adopts a bolt connecting assembly with stronger anti-loosening effect, as shown in Figure 4 , the bolt connecting assembly comprises a hexagonal flange bolt and an elastic gasket 31, the size of the elastic gasket 31 is larger than the size of the flange, so as to provide a larger pressing area and ensure the reliability of the connection. Of course, in other embodiments, the connecting bolt assembly 3 can adopt the form of a common bolt plus a gasket or an elastic gasket.

[0037] The above-mentioned is only a preferred embodiment of the present application, and is not used to limit the present application, the patent protection scope of the present application is subject to the claims, and any equivalent structural changes made according to the content of the specification and the drawings of the present application should also be included in the protection scope of the present application.
