Technical Field

[0001] The present application relates to the technical field of connector electrical connection, and more specifically, to a plate-type connector, a distribution box provided with the connector, and a vehicle. Background Art

[0002] At present, there are various ways to connect connectors. In the prior art, electrical connection is mainly achieved by setting male and female terminals that cooperate with each other in the connector. The male and female terminals are mainly in the form of socket terminals, screw terminals, plug terminals, spring terminals, etc. New energy vehicles have a large load demand during operation. It is easy for the contact parts and mating parts in high-voltage connectors to have poor contact. In mild cases, it affects the reliability of contact and causes instant power failure. In severe cases, it will seriously affect driving safety. At the same time, because the connector is often set inside the distribution box, when the distribution box is repaired, the box body needs to be opened to disconnect the connector, which causes obstacles to power connection and power disconnection.

[0040] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is obvious to those skilled in the art that the present application embodiments can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application embodiments, some technical features well known in the art are not described.

[0041] Herein, ordinal numbers such as “first” and “second” cited in the present application are merely identifications and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term “first component” itself does not imply the existence of the “second component”, and the term “second component” itself does not imply the existence of the “first component”.

[0042] In this document, “upper”, “lower”, “front”, “back”, “left”, “right”, etc. are only used to indicate the relative position relationship between related parts, rather than to limit the absolute positions of these related parts.

[0043] In this document, “equal”, “same”, etc. are not strictly limited in a mathematical and / or geometric sense, but also include errors that can be understood by those skilled in the art and are allowed in manufacturing or use.

[0044] Unless otherwise stated, the numerical ranges herein include not only the entire range within its two endpoints but also include several sub-ranges contained therein.

[0045] like Figure 1 As shown, according to an embodiment of the present utility model, the connector assembly of the embodiment shown includes a conductive copper bar 1, an elastic copper bar 2, an insulating housing 3, a rivet 4, a first conductive copper bar 5 and a second conductive copper bar 6.

[0046] Specifically, the shape of the insulating shell 3 can be a cylinder or a prism. In this embodiment, the shape of the insulating shell 3 is preferably a quadrangular prism. An insertion hole 31 for the elastic copper busbar 2 is opened on the top of the insulating shell. The size of the insertion hole is suitable for the transition fit of the main body of the elastic copper busbar. When the elastic copper busbar 2 is inserted into the insulating shell 3, the insertion hole 31 can squeeze the abutment portion 22 of the elastic copper busbar 2, and the abutment portion can retract into the through hole formed on the main body 21 due to processing, so as to ensure that the elastic copper busbar 2 can be smoothly inserted into the insulating shell.

[0047] In some structures of related technologies, the conduction is mainly controlled by relays, which may fail. At the same time, there are many terminal connection solder joints in the connector. High voltage or looseness during use will cause unreliable electrical connection in the connector. Figure 1As shown, the difference between the present application and the prior art is that the conductive circuit can be switched on and off at the connector assembly by inserting and removing the elastic copper busbar, which is easy to operate; at the same time, the large electrical contact area between the elastic copper busbar and the conductive copper busbar ensures the stability of the internal electrical connection of the connector, thereby reducing the phenomenon of unstable internal electrical connection of the connector.

[0048] Furthermore, if Figure 1 As shown, the conductive copper bar 1 is in the shape of a plate, and the conductive copper bar 1 can fit tightly with the inner wall of the insulating housing 3. At the same time, the two conductive copper bars 1 are arranged at intervals inside the insulating housing 3, and the opposite directions of the two conductive copper bars 1 are both planes, which are set as electrical connection surfaces. Due to the limitation of the insulating housing, when the elastic copper bar 2 is inserted, the conductive copper bar 1 will apply a clamping force to the elastic copper bar 2, so that the elastic copper bar 2 is kept between the conductive copper bars 1. Thereby, when the elastic copper bar 2 is inserted, the two conductive copper bars 1 can be connected; when the elastic copper bar 2 is pulled out, since the two conductive copper bars 1 are arranged at intervals, the electrical connection between the conductive copper bars 1 can be disconnected.

[0049] Specifically, the distance between the two conductive copper bars is 3.6mm, and the interference on one side is 0.2mm, which can ensure compression deformation without causing plastic deformation, and keep it within the elastic deformation range, and can be used repeatedly.

[0050] like Figure 2 As shown, according to an elastic copper busbar of this embodiment, the elastic copper busbar 2 includes a main body 21 and an abutment portion 22 , the main body 21 is a plate-shaped portion of the elastic copper busbar 2 , and the abutment portion 22 is formed by stamping and bending the elastic copper busbar 2 .

[0051] Furthermore, the abutting portion 22 includes a connecting portion and a contact portion after stamping. Due to the stamping effect, the connecting portion bends toward the extending direction of the abutting portion, and the contact portion is parallel to the electrical connection surface of the conductive copper busbar, ensuring reliable contact between the contact portion and the electrical connection surface. At the same time, due to the bending of the connecting portion, a certain degree of elasticity can be guaranteed for the abutting portion 22. When the abutting portion 22 is inserted and squeezed, it can avoid the insertion hole 31, and at the same time, it can automatically expand after insertion and make electrical contact with the electrical connection surface.

[0052] Furthermore, in order to ensure that the elastic copper bar 2 does not deviate after being inserted into the connector, the number of abutment portions on both sides of the elastic copper bar is the same. Preferably, as Figure 2 As shown, nine abutment portions are respectively provided on both sides of the elastic copper busbar 2 to ensure that the abutment forces applied on both sides are balanced.

[0053] Furthermore, to facilitate assembly, the thickness of the main body 21 is 3 mm, and the height of the abutting portion 22 is 0.5 mm.

[0054] Furthermore, if Figure 2As shown, the elastic copper busbar 2 is provided with a chamfer at one end inserted into the connector to form an insertion portion 23. When the insertion portion passes through the insertion hole 31, due to the small contact area of ​​the tip of the insertion portion 23, it can provide effective guidance during insertion, thereby preventing the elastic copper busbar 2 from getting stuck when inserted into the insulating housing 3.

[0055] Furthermore, the outer surface of the main body 21 of the elastic copper bus 2 is covered with an insulating layer, and the material of the insulating layer can be plastic, rubber or other insulating materials with certain elasticity and plasticity. The setting of the insulating layer can ensure that the elastic copper bus 2 is insulated when plugging and unplugging, and electric shock will not occur.

[0056] Furthermore, the material of the elastic copper busbar 2 can be beryllium copper. The material of the elastic copper busbar 2 needs to have certain elasticity and excellent electrical conductivity. The elastic function needs to be reliable and can remain unchanged for a long time. Beryllium copper is a high-grade elastic material with the best performance among copper alloys. It has a series of excellent physical, chemical and mechanical properties such as high strength, elasticity, hardness, fatigue strength, small elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, and no sparks when impacted, which can fully meet the material requirements of this patent.

[0057] Furthermore, the inserting part 23 is subjected to local surface treatment, and a silver-nickel alloy is electroplated on the surface. The silver-nickel alloy is an alloy material with excellent corrosion resistance, high strength and high temperature stability. It is composed of two metal elements, silver and nickel, and is usually prepared in a weight ratio of 75% silver and 25% nickel. Due to the good strength and corrosion resistance of the silver-nickel alloy, the outer surface of the inserting part can be fully protected.

[0058] like Figure 3 As shown, according to an embodiment of the utility model, a groove 327 is preferably provided at the insertion hole 31, and the projection of the groove 32 along the axial direction of the insulating housing 3 can include the projection of the abutment portion 22 along the axial direction of the insulating housing 3. The groove can leave a certain escape space, and since the abutment portion of the elastic copper busbar 2 will be opened after entering the insulating housing 3, the escape space can ensure that the elastic copper busbar 2 will not be stuck in the insertion hole 31 when being pulled out, and at the same time, the distance from the bottom edge of the groove 32 to the center line of the insulating housing is greater than the distance from the electrical connection surface to the center line of the insulating housing.

[0059] According to the utility model, another embodiment is provided, which is not shown in the drawings in the specification. According to this embodiment, the elastic copper bar is a U-shaped copper bar, and the abutting portion of the elastic copper bar includes an elastic bending section and two straight sections, the two ends of the elastic bending section are respectively connected to the straight sections, and the straight sections abut against the electrical connection surface.

[0060] Specifically, the curved section includes n curved conductive metal sheets stacked and arranged in the thickness direction, and the straight section is formed by fastening and bonding multiple conductive metal sheets or coated with a solid conductive layer on the outer surface to ensure a certain rigidity and strength. Since the curved section has a certain elasticity, it can push the straight section to abut against the electrical connection surface, so that the U-shaped copper busbar can be clamped between the two conductive copper buses 1.

[0061] Furthermore, the two straight sections are provided with a lifting portion at one end away from the bent conductive metal sheet, and the two lifting portions are bent toward the conductive copper busbar, respectively, and the lifting portions extend to the outside of the insulating housing 3 through the insertion hole 31. The lifting portion is coated with an insulating layer, and the material of the insulating layer can be plastic, rubber or other insulating materials with certain elasticity and plasticity. According to this embodiment, the safe and convenient extraction of the U-shaped copper busbar can be ensured.

[0062] Furthermore, the insulating housing 3 is formed with a mounting seat 33 in a direction away from the insertion hole 31 . The mounting seat 33 is formed by extending in a direction perpendicular to the axis of the insulating housing 3 . The mounting seat 33 is formed integrally with the insulating housing 3 .

[0063] Furthermore, one end of the conductive copper busbar 1 close to the mounting seat 33 is bent and fits with the mounting seat 33 . The mounting seat 33 is provided with a through hole, and the conductive copper busbar 1 is riveted and fixed to the mounting seat 33 at the through hole.

[0064] Specifically, the rivet 4 is inserted into the through hole, and the conductive copper bus 1 and the mounting seat 33 are riveted together by deformation and extrusion.

[0065] For example, in order to ensure the sealing of the entire connector, the embodiments of the present application provide a corresponding sealing structure.

[0066] Specifically, according to an embodiment not shown in the drawings of the specification, a sealing ring is provided along the opening of the insertion hole 31 of the insulating shell 3, and an annular groove is provided on the outer wall of the sealing ring, and the insertion hole cooperates with the annular groove; the inner wall of the sealing ring is interference fit with the elastic copper busbar to ensure the sealing of the connector assembly.

[0067] Furthermore, the sealing ring is provided with a chamfer in a direction toward the inside of the insulating housing, which is used for guiding the elastic copper busbar when it is pulled out.

[0068] Likewise, according to the embodiment of the present invention, the mounting seat 33 of the connector assembly is formed with an annular boss along the edge, and the annular boss is interference-fitted with the outer wall of the box body to achieve sealing of the connector assembly.

[0069] The utility model also provides a distribution box, comprising:

[0070] Box;

[0071] Relay;

[0072] The first conductive copper bar 5 and the second conductive copper bar 6 are arranged in the box.

[0073] The connector assembly has a mounting hole formed on the box body, and the connector assembly is mounted on the outer wall of the box body through the mounting hole. The two conductive copper bars of the connector assembly pass through the mounting hole and are electrically connected to the first conductive copper bar 5 and the second conductive copper bar 6 respectively. The first conductive copper bar 5 and the second conductive copper bar 6 are electrically connected to the relay to form a conductive circuit. The conductive circuit inside the distribution box is electrically connected to the outside world, and the on and off of the conductive circuit can be controlled outside the distribution box by plugging and unplugging the elastic plug bar.

[0074] The utility model further provides a vehicle, comprising:

[0075] Power battery;

[0076] Rigid conductors; and

[0077] The aforementioned distribution box has multiple rigid conductor points connected to the power battery, which supplies power to the distribution box.
