Connector and electric equipment

Technical Field

The present application relates to an electrical connection structure, and more particularly, to a connector and an electric device.

Background

Connectors, particularly quick-change plug connectors, are widely used in electrical connection structures for various electrical components because of their ease and rapidity of operation. For example, in a vehicle or the like, a battery and an electric component, the electric component and each other are generally electrically connected by a connector. The improvement of the convenience, reliability and durability of the connector has been the subject of research in the industry.

SUMMERY OF THE UTILITY MODEL

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a connector which can avoid abrasion of the connector due to repeated insertion and extraction operations and can improve convenience of use, reliability, and durability, and an electric device using the connector.

To achieve the above object, a first aspect of the present application provides a connector including connection terminals, a connector interface wall formed around the connection terminals, and at least one jacket, each jacket being mounted to the connector interface wall in a manner of sandwiching the connector interface wall, and extending from one side of the connector interface wall to the other side across an interface wall edge of the connector interface wall.

Therefore, the sheath is arranged on the connector interface wall which is most easily worn, so that the wear of the connector caused by repeated inserting and pulling actions can be prevented or reduced, the conditions of poor connection, damage and the like of the connector due to wear are avoided, and the use reliability and the use durability are improved.

In addition, since the boot is attached to the connector interface wall so as to sandwich the connector interface wall, no extra operation is required during the insertion and extraction operation, thereby ensuring the convenience of use of the connector.

Furthermore, since the boot extends from one side of the connector interface wall to the other across the interface wall edge of the connector interface wall, protection can be provided to the connector interface wall from the edge to the wall surface, and wear of the connector interface wall is reliably avoided.

In some embodiments, the at least one boot is mounted at a different location on the connector interface wall.

This protects the entire connector interface wall, and reliably prevents the connector, particularly the connector interface wall, from being worn.

In some embodiments, the sheath has a first sheet, a second sheet, a joint connecting the first sheet and the second sheet, the sheath configured to have a U-shaped cross-section.

Therefore, the sheath is simple in structure and easy to process. When the sheath is installed on the connector interface wall, the sheath is inserted into the connector interface wall to realize installation, and the installation is convenient.

In some embodiments, the sheath further has a force application portion located on a side of the sheath contacting the connector interface wall in the mounted state and integrally provided to the first and second piece portions.

Because the force application part is arranged and is positioned at the contact side of the sheath and the connector interface wall in the installation state, the sheath can be firmly clamped on the connector interface wall, so that the sheath cannot fall off from the connector interface wall due to the plugging action; moreover, the plugging and unplugging action of the opponent piece relative to the connector cannot be hindered, and the opponent piece in plugging and unplugging cannot be damaged. In addition, the force applying parts are arranged on the first sheet part and the second sheet part, so that the clamping force can be enhanced, and the position of the sheath can be kept stable.

In some embodiments, the force applying portion is constituted by a hook, and the hook provided to the first sheet portion is constituted by bending an end of the first sheet portion; the hook provided to the second piece is formed by bending a distal end of the second piece.

Therefore, the sheath is ensured to be an integral structure, the structure of the sheath is simplified, and the structure of the connector is further simplified. And the manufacturing process of the sheath is simple.

In some embodiments, the at least one sheath includes two first sheaths respectively mounted on the connector interface wall at positions opposing each other across the connection terminal.

Therefore, the sheath is arranged on the position opposite to the connector interface wall through the connecting terminal, so that the connector and the opponent piece connected with the connector are stressed evenly, and the situations of poor installation, poor electric connection and even damage caused by uneven stress are reduced.

In some embodiments, the at least one sheath further includes two second sheaths respectively mounted on the connector interface wall at positions opposite across the connection terminals, and the second sheaths and the first sheaths are mounted on the connector interface wall at positions different from each other.

Thus, the connector interface wall can be provided with full circumferential protection against wear by four sheaths opposite each other; and the connector and the opponent part connected with the connector can be uniformly stressed, and poor installation, poor electric connection and even damage and the like caused by uneven stress can be avoided.

In some embodiments, the connector interface wall is formed to be oblong in plan view; the first sheath is formed into a linear shape on the whole in the length direction; the second sheath is formed into an arc shape on the whole in the length direction.

Thus, the first boot can be attached to the straight wall portion of the oblong connector interface wall and the second boot can be attached to the arcuate wall portion of the oblong connector interface wall, thereby providing protection against wear over the entire circumference of the connector interface wall.

In some embodiments, the connecting portion has a rounded arc shape.

Thus, when the opponent connector is inserted into the connector, the opponent connector can be smoothly guided into the space surrounded by the connector interface wall, and damage to the opponent connector due to collision or the like at the time of insertion can be avoided.

In some embodiments, a recess is provided in the connector interface wall that engages with the boot in the installed state.

Thus, by providing the recessed portion into which the sheath is fitted on the connector interface wall, it is possible to effectively avoid a problem such as the sheath sliding along the connector interface wall. Moreover, the surface of the sheath in the mounting state and the wall surface of the surrounding connector interface wall can be positioned on the same plane by arranging the concave part, so that the influence of the sheath on the size of the connector interface can be avoided.

In some embodiments, at least one reinforcing rib is provided on the outside of the connector interface wall.

Therefore, the strength of the connector interface wall can be improved by arranging the reinforcing rib plate, and the stability of the connector interface wall during the plugging and unplugging action is further improved, so that the situation that the connector interface wall is easily deformed and damaged or abraded during the plugging and unplugging action can be further avoided.

A second aspect of the present application provides a powered device comprising a battery electrically connected with an electrical component through a connector provided by the first aspect of the present application, the connector being mounted to either one of the battery and the electrical component.

Therefore, the connector provided by the first aspect of the present application can be applied to an electrical connection scenario between an electrical component and a battery, and is helpful for realizing quick installation, quick replacement, and the like of the battery. Moreover, the battery has the advantages of repeated plugging and unplugging and durability due to abrasion resistance, and is particularly suitable for the situation of repeated battery replacement. Of course, the connector provided in the first aspect of the present application is also applicable to other scenarios where electrical components are connected.

In a vehicle or the like, a battery and an electric component, the electric component and each other are generally electrically connected by a connector. With the development of new energy vehicles, there is an urgent need to be able to quickly install or replace batteries on the vehicles. This also places a demand on the connector that achieves electrical connection of the battery to the electrical components (including the electrical connection lines) on the vehicle side to resist repeated insertion and removal.

After research, the inventor of the present application finds that one of the factors affecting the repeated insertion and extraction resistance of the connector is rapid wear of the interface wall of the connector due to repeated insertion and extraction, which causes the connection of the connector to be loosened, poor electrical connection, damage of the connector, and other adverse conditions, and also has potential safety hazards.

In view of the above problems, the inventors of the present application have found that, if an anti-abrasion measure can be accurately applied to the interface wall of the connector, the connector can be effectively prevented from being abraded, repeated insertion and extraction resistance of the connector can be improved, and durability of the connector in use can be greatly improved.

Accordingly, in order to solve the above-described problems, the present application provides a connector and an electric device using the connector in connection of a battery and an electrical component.

Fig. 1 is a schematic structural diagram of a vehicle 1000 according to an embodiment of the present application. As shown in fig. 1, the vehicle 1000 may be a fuel-oil vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid electric vehicle, or a range-extended vehicle. Vehicle 1000 carries battery 100, and battery 100 may be provided at the bottom, head, or tail of vehicle 1000. The battery 100 may be used for power supply of the vehicle 1000, for example, the battery 100 may serve as an operation power source of the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300, wherein the controller 200 is configured to control the battery 100 to supply power to the motor 300, for example, the power may be used for starting, navigating, and operating power demand during driving of the vehicle 1000.

In some embodiments of the present application, the battery 100 may be used not only as an operating power source of the vehicle 1000, but also as a driving power source of the vehicle 1000, instead of or in part of fuel or natural gas, to provide driving power for the vehicle 1000.

Fig. 2 is a schematic structural view schematically showing a battery box according to an embodiment of the present application. The battery 100 includes a case 201 and a battery cell 202, and the battery cell 202 is accommodated in the case 201. The case 201 is used to provide a receiving space for the battery cells 202, and the case 201 may have various structures. In some embodiments, the case 201 may include a first portion 201a and a second portion 201b, the first portion 201a and the second portion 201b cover each other, and the first portion 201a and the second portion 201b together define a receiving space for receiving the battery cell 202. The second part 201b may be a hollow structure with one open end, the first part 201a may be a plate-shaped structure, and the first part 201a covers the open side of the second part 201b, so that the first part 201a and the second part 201b jointly define a receiving space; the first portion 201a and the second portion 201b may be both hollow structures with one side open, and the open side of the first portion 201a is covered on the open side of the second portion 201 b. Of course, the first portion 201a and the second portion 201b may form the case 201 in various shapes, such as a cylinder, a rectangular parallelepiped, and the like.

In order to meet different power requirements, the battery 100 may include a plurality of battery cells 202, and the battery cells 202 refer to the smallest unit constituting a battery module or a battery pack. A plurality of battery cells 202 may be connected in series and/or in parallel via electrode terminals to be applied to various applications. The battery referred to in the present application may include a battery module or a battery pack. The plurality of battery cells 202 may be connected in series, in parallel, or in series-parallel, where series-parallel refers to a mixture of series connection and parallel connection. The battery in the embodiment of the application can be directly composed of a plurality of battery monomers 202, or a battery module can be firstly composed, and then the battery module is composed of the battery.

In some embodiments, the battery cells 202 may be a lithium ion battery, a sodium ion battery, a magnesium ion battery, or the like, which is not limited in this application. The battery cells 202 may be in the shape of a cylinder, a flat body, a rectangular parallelepiped, or other shapes, which is not limited in the embodiments of the present application. The battery cells 202 are generally divided into three types in an encapsulated manner: the cylindrical battery monomer, the square battery monomer and the soft package battery monomer are not limited in the embodiment of the application. The cylindrical battery cells may be further classified into cylindrical battery cells, polygonal prismatic battery cells, and the like according to the sectional shapes of the cylindrical surfaces.

Additionally, the battery cells 202 generally include end caps, a housing, and an electrical core assembly. The end cap refers to a member that covers an opening of the case to insulate the internal environment of the battery cell 202 from the external environment. Without limitation, the shape of the end cap may be adapted to the shape of the housing to fit the housing. Alternatively, the end cap may be made of a material (e.g., an aluminum alloy) having a certain hardness and strength, so that the end cap is not easily deformed when being extruded and collided, and thus the single battery 202 may have a higher structural strength and the safety performance may be improved. The end cap may be provided with functional components such as electrode terminals. The electrode terminals may be used to electrically connect with the electric core assembly for outputting or inputting electric power of the battery cells 202. The end cap may be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., which is not limited in this embodiment. In some embodiments, insulation may also be provided on the inside of the end cap, which may be used to isolate the electrical connections within the housing from the end cap to reduce the risk of shorting. Illustratively, the insulator may be plastic, rubber, or the like.

The housing is an assembly for mating with the end caps to form an internal environment for the cell 202, wherein the formed internal environment may be used to house the cell assembly, electrolyte (not shown in the figures), and other components. The housing and the end cap may be separate components, and an opening may be formed in the housing, and the opening may be covered by the end cap to form an internal environment of the battery cell. The end cap and the housing may be integrated, and specifically, the end cap and the housing may form a common connecting surface before other components are inserted into the housing, and when the interior of the housing needs to be sealed, the end cap covers the housing. The housing may be of various shapes and sizes, such as rectangular parallelepiped, cylindrical, hexagonal prism, etc. Specifically, the shape of the housing may be determined according to the specific shape and size of the electric core assembly. The material of the housing may be various, for example, copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., which is not limited in this application.

The cell assembly is the component of the cell 202 where the electrochemical reaction takes place. One or more electrical core assemblies may be contained within the housing. The cell assembly is mainly formed by winding or stacking a positive electrode sheet and a negative electrode sheet, and a separator is generally provided between the positive electrode sheet and the negative electrode sheet. The portions of the positive and negative electrode tabs having the active material constitute the main body of the cell assembly, and the portions of the positive and negative electrode tabs having no active material each constitute a tab (not shown in the drawings). The positive electrode tab and the negative electrode tab may be located at one end of the main body portion together or at both ends of the main body portion, respectively. In the charging and discharging process of the battery, the anode active material and the cathode active material react with the electrolyte, and the tabs are connected with the electrode terminals to form a current loop.

The electric power is drawn from the battery as described above and output to an electric component (including an electric connection line) may be connected by a connector. Of course, the connector is also suitable for other usage scenarios, such as connection between any two electrical components (where an electrical component includes an electrical connection wire or a wire harness). Connections between non-electrical components, connections between electrical components and non-electrical components, and the like. In addition, although the present application describes a vehicle as an example of a device using a connector, it is obvious that the present application does not limit the device using a connector.

Fig. 3 schematically illustrates a schematic diagram of a connector 203 according to an embodiment of the present application. The connector 203 includes connection terminals 231, a connector interface wall 232 formed around the connection terminals 232, and at least one boot 250, each boot 250 being mounted to the connector interface wall 232 in a manner to sandwich the connector interface wall and extending from one side of the connector interface wall 232 to the other across the interface wall edge 233 of the connector interface wall 232.

As shown in fig. 3, the connector interface wall 232 surrounds the connection terminals 231. The connection terminal 231 is used to achieve electrical connection, and includes, for example, a metal terminal or a contact. For example, the connection terminal 231 may transmit electric power of the battery to the outside of the case 201, and may be partially (for example, a connector base portion 239 below the frame 235 in the figure) located inside the case 201 and partially (for example, at least a portion above the frame 235 in the figure) exposed to the outside of the case 201.

When the connector 203 is attached to a target position, the first flange 234 shown in fig. 3 may be attached to the target position by, for example, screwing. The second flange 236 can also be brought into contact with the periphery of the mounting target position, and support of the connector 203 is achieved.

In the example shown in fig. 3, the connector interface wall 232 forms a closed shape around the connection terminal 231, and is disposed upright with respect to the frame body 235. Here, the present embodiment is equally applicable even if the connector interface wall 232 does not form a completely closed loop.

The connector interface wall 232 according to the embodiment of the present invention may be made of, for example, resin. As a specific example, the connector 203 is mainly formed by a resin molded body.

The number of the sheaths in the embodiment of the present application may be one or more; the structure may be an integral structure or a plurality of the structures may be separately provided. In fig. 3, 4 sheaths 250 are shown as an example, which are arranged separately from one another. However, an annular sheath may be provided around the entire circumference of the connector interface wall 232.

The material of the sheath is not particularly limited as long as the technical object of the present application can be achieved, and for example, a metal or a resin having good wear resistance can be selected, and examples of the metal include stainless steel, an alloy, and the like.

Therefore, the sheath 250 is provided on the connector interface wall 232 which is most likely to be worn, so that the wear of the connector 203 due to repeated insertion and extraction operations can be prevented or reduced, and the occurrence of poor connection, damage and the like of the connector 203 due to wear can be avoided, thereby improving the use reliability and the use durability.

In addition, since the boot 250 is attached to the connector interface wall 232 so as to sandwich the connector interface wall 232, no extra operation is required during the insertion and removal operation, thereby ensuring the convenience of use of the connector 203.

Furthermore, because the boot 250 extends from one side of the connector interface wall 232 to the other across the interface wall edge 233 of the connector interface wall 232, protection is provided from the edge of the connector interface wall 232 to the wall, and wear of the connector interface wall 232 is reliably avoided.

In some embodiments, as shown in fig. 3, at least one boot 250 is mounted at a different location on the connector interface wall 232. Specifically, the boot 250 may be distributively mounted on the connector interface wall 232.

This can protect the entire connector interface wall 232, and can reliably prevent the connector 203, particularly the connector interface wall 232, from being worn.

In some embodiments, as shown in fig. 3, the sheath 250 has a first tab 253, a second tab 254, and a connection 255 connecting the first tab 253 and the second tab 254, the sheath 250 configured to have a U-shaped cross-section.

Specifically, for example, the sheath 250 may be formed by bending a sheet-like member, the first sheet 253 and the second sheet 254 may be connected by a connecting portion 255 serving as a bent portion, and a substantially U-shaped cross section may be formed with the connecting portion 255 as a bottom and the first sheet 253 and the second sheet 254 as both vertical sides, and may have an opening 257. When the boot 250 is attached to the connector interface wall 232, the opening 257 is inserted into the connector interface wall 232 in alignment with the connector interface wall 232 until the connecting portion 255 abuts against the interface wall edge 233 of the connector interface wall 232.

Therefore, the sheath is simple in structure and easy to process. When the sheath is installed on the connector interface wall, the sheath is inserted into the connector interface wall to realize installation, and the installation is convenient.

In some embodiments, as shown in fig. 3 to 5, the sheath 250 further has a force application portion 256, the force application portion 256 being located on a side of the sheath 250 contacting the connector interface wall 232 in the mounted state and integrally provided to the first and second tab portions 253 and 254.

Specifically, in order to make it difficult for the sheath 250 attached to the connector interface wall 232 to come off or shift, a clamping portion (i.e., a biasing portion) for the connector interface wall 232 is provided on the clamping surface side of the sheath 250, that is, on the side of the surface in contact with the connector interface wall 232. The specific form of the clamping portion is not limited as long as it can apply a clamping force to the connector interface wall 232.

Since the urging portion 256 is provided and the urging portion 256 is located on the side of the sheath 250 that contacts the connector interface wall in the attached state, the sheath 250 can be firmly held by the connector interface wall 232 so that the sheath 250 does not fall off the connector interface wall 232 due to the insertion and removal operation; moreover, the insertion and removal operation of the counterpart (not shown) with respect to the connector 203 is not hindered, and the counterpart during insertion and removal is not damaged. In addition, providing the biasing portion 256 in both the first piece 253 and the second piece 254 can enhance the clamping force and contribute to holding the sheath 250 in a stable position.

In some embodiments, as shown in fig. 3 to 5, the force application portion 256 is formed of a hook-shaped member, and the hook-shaped member (i.e., the force application portion 256) provided to the first sheet portion 253 is formed by bending an end of the first sheet portion 253; the hook provided to the second piece 254 is formed by bending the end of the second piece 254.

As shown in fig. 3, 4, and 5, the biasing portion 256 is formed by folding back the ends of the first and second piece portions 253 and 254. When the folded-back piece portions are pressed against the first and second piece portions 253, 254 integral therewith, a restoring force is generated to separate the folded-back piece portions from the first and second piece portions 253, 254 integral therewith, thereby forming a clamping action against the connector interface wall 232. The folded back tab portion may be referred to as a first clip, a first clip 256a being shown in fig. 5. In order to further increase the clamping force, a part of the first clip 256a may be slightly bent in a direction away from the first and second piece portions 253 and 254 which are integrated therewith to form the second clip 256b, whereby the clamping force can be further increased.

This ensures that the sheath 250 has an integral structure, and simplifies the structure of the sheath 250 and thus the structure of the connector. Also, the manufacturing process of the sheath 250 is simple and has a sufficient clamping force.

In some embodiments, as shown in fig. 3, the at least one sheath 250 includes two first sheaths 251, and the two first sheaths 251 are respectively mounted on the connector interface wall at positions opposite to each other across the connection terminals 231.

Thus, by attaching the sheath to the connector interface wall 232 at a position facing the connector interface wall 231 across the connection terminal 231, the connector 203 and the counterpart connected thereto are uniformly subjected to a force, and the occurrence of poor attachment, poor electrical connection, and damage due to uneven application of a force can be reduced.

In some embodiments, as shown in fig. 3, the at least one sheath 250 further includes two second sheaths 252, two second sheaths 251 are respectively mounted on the connector interface wall 232 at positions opposite across the connection terminals 203, and the second sheaths 252 and the first sheaths 251 are mounted on the connector interface wall at positions different from each other.

Thus, the connector interface wall 232 can be provided with full circumferential wear protection by four sheaths opposing each other; and the connector and the opponent part connected with the connector can be ensured to be stressed evenly, and poor installation, poor electric connection and even damage and the like caused by uneven stress can be avoided.

In some embodiments, as shown in fig. 3-5, the connector interface wall 232 is formed to be oblong in plan view; the first jacket 251 is formed in a linear shape as a whole in the longitudinal direction; the second sheath 252 is formed in an arc shape as a whole in the longitudinal direction.

Thus, the first boot 251 can be attached to the straight wall portion of the oblong connector interface wall 232, and the second boot 252 can be attached to the arcuate wall portion of the oblong connector interface wall 232, thereby providing protection against wear over the entire circumference of the connector interface wall 232.

In some embodiments, as shown in fig. 3-5, the connecting portion 255 has a rounded arcuate shape.

Thus, when the opponent connector is inserted into the connector 203, the opponent connector can be smoothly guided into the space surrounded by the connector interface wall 232, and damage to the opponent connector due to collision or the like at the time of insertion can be avoided.

In some embodiments, as shown in fig. 3, the connector interface wall 232 is provided with a recess that engages the boot 250 in the installed state. When the sheath 250 includes the first sheath 251 and the second sheath 252, the recess has a first recess 240 fitted with the first sheath 251 and a second recess 241 fitted with the second sheath 252. In addition, as a preferred embodiment, the surfaces (the surfaces on the connection terminal side) of the first and second sheaths 251 and 252 after mounting and the surface (the surface on the connection terminal side) of the connector interface wall may be positioned in the same plane, and no step portion may be provided.

Thus, by providing the recessed portions 240 and 241 into which the sheath is fitted on the connector interface wall 232, it is possible to effectively avoid troubles such as the sheath sliding along the connector interface wall. Moreover, the surface of the sheath in the mounting state and the wall surface of the surrounding connector interface wall can be positioned on the same plane by arranging the concave part, so that the influence of the sheath on the size of the connector interface can be avoided.

In some embodiments, as shown in fig. 3, at least one reinforcing rib is provided on the outside of the connector interface wall 232.

Specifically, in fig. 3, 4 reinforcing ribs 237 (only 2 shown) are shown disposed around the connector interface wall 232. These reinforcing ribs 237 are fixed to and integrated with the connector interface wall 232 from the outer peripheral side of the connector interface wall 232.

Of course, as for the connector base portion 239, the second reinforcing rib 238 is also provided.

Therefore, the strength of the connector interface wall 232 can be improved by providing the reinforcing rib plate, and the stability of the connector interface wall during the insertion and extraction actions can be further improved, so that the situation that the connector interface wall is easily deformed and damaged or abraded during the insertion and extraction actions can be further avoided.

A second aspect of the present application provides a powered device comprising a battery electrically connected to an electrical component through a connector 203 provided in the first aspect of the present application, the connector being mounted to either the battery or the electrical component.

Therefore, the connector provided by the first aspect of the present application can be applied to an electrical connection scenario between an electrical component and a battery, and is helpful for realizing quick installation, quick replacement, and the like of the battery. Moreover, the wear-resistant battery has the advantages of repeated plugging and unplugging and durability, and is particularly suitable for the situation of repeated battery replacement. Of course, the connector provided in the first aspect of the present application is also applicable to other scenarios of electrical component connection.

Specific embodiments of the present application will be described below as examples.

As shown in fig. 3 to 5, a metal sheath, comprising 2 first sheaths 251 and 2 second sheaths 252, is mounted on the connector interface wall 232 (also referred to as "bezel") of the quick-change connector. The first sheaths 251 are disposed opposite one another on the straight wall portions of the connector interface wall 232 and the second sheaths 252 are disposed opposite one another on the curved wall portions of the connector interface wall 232.

In addition, on the connector interface wall 232 made of resin, a certain thickness of space (i.e., forming a recess) is reserved at the installation position of the first sheath 251 and the second sheath 252 respectively, so as to ensure that the installed first sheath 251 and second sheath 252 do not affect the frame opening size of the original connector. Therefore, the strength of the connector interface wall is ensured by the metal sheath when the male and female connectors are mutually matched, and the connector can be prevented from being abraded.

In addition, each metal sheath opening is provided with two hook-shaped pieces so as to ensure that the metal sheath is not easy to fall off when being plugged and pulled out, and ensure the stability of the sheath structure. The hooks are arranged on two sides of the metal sheath, so that the retention force of the metal sheath nested with the connector can be improved.
