Description

Technical Field

[0002] A charger is a device that connects an appliance to a power source. Chargers vary in appearance, grade, size, and type depending on the country or region. Each country has its own government-set standards.

[0003] In order to facilitate carrying and storage, existing chargers are often designed to be foldable. Foldable chargers achieve conduction between power pins and circuit boards through electrical connectors. As the power pins are unfolded, the electrical connectors are electrically connected to each other. Further, in order to ensure good conduction between the electrical connector and the power pins, a protrusion is provided at the end of the power pin. As the power pins are unfolded, the protrusion is pressed against the electrical connector. However, the elastic portion of the electrical connector in the existing foldable charger is easily deformed during the folding process of the power pins. Moreover, once the existing electrical connectors are used for a long time, the electrical connector and the power pins are prone to poor contact. Utility Model Content

[0005] Specifically, on the one hand, an embodiment of the utility model provides an electrical connector, comprising: a supporting portion having a front area and a connecting area connected sequentially in a first direction; a contact portion connected to the connecting area; and a fixing portion connected to a side of the supporting portion away from the front area.

[0006] In an embodiment of the present invention, the supporting portion has a first side in a first direction, and the contact portion is connected to the first side.

[0007] In an embodiment of the present invention, the contact portion includes a bending surface and a contact surface, one end of the bending surface is connected to the contact surface, and the other end of the bending surface is connected to the first side.

[0008] In an embodiment of the present invention, the connection area is provided with a groove on the first side, the contact portion is provided in the groove, and forms a gap with a side wall of the groove.

[0009] In an embodiment of the present invention, the fixing portion includes a clamping portion and a connecting portion, and the connecting portion is respectively connected to the clamping portion and the supporting portion.

[0010] On the other hand, a charger provided by an embodiment of the utility model includes: a cover body; a rotating member movably connected to the cover body, the rotating member being provided with a contact terminal; an electrical connection pin connected to the rotating member and electrically connected to the contact terminal, the electrical connection pin being rotatable relative to the cover body; and, as the aforementioned electrical connection member, the electrical connection member is connected to the cover body, and the contact portion is elastically connected to the contact terminal.

[0011] In an embodiment of the present invention, the contact portion includes a contact surface, and the contact surface is elastically connected to the contact terminal.

[0012] In an embodiment of the present invention, the fixing portion is connected to the rear region, a first limiting portion is provided on the cover body corresponding to the front region, and the front region is cooperatively connected with the first limiting portion.

[0015] It can be seen from the above that the above technical features of the utility model can have one or more of the following beneficial effects:

[0016] Since the electrical connector is elastically connected to the electrical connection of the electronic device during use, long-term elastic connection will cause the electrical connection to deform, resulting in poor contact of the electronic device. For example, if the contact portion is arranged in the front area of ​​the support portion, the front area will deform in the direction of the elastic force under the elastic force, and the support portion will deform relative to the fixed portion, resulting in poor contact between the contact portion and the electrical connection of the electronic device. By arranging the contact portion in the connection area of ​​the electrical connector, when the support portion is subjected to the elastic force, the deformation of the connection area in the direction of the elastic force will be smaller than that of the front area, and the front area interferes with other components in the electronic device, further hindering the deformation of the support portion, so that the electrical connector has better pressure resistance and durability, can withstand greater pressure, is not easily deformed or damaged, can greatly reduce the occurrence of poor contact problems, and improve the life of electronic components.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 and Figure 2 The embodiment of the utility model provides an electrical connector 1. The electrical connector 1 includes, for example, a support portion 412, a contact portion 411, and a fixing portion 420. The electrical connector 1 is made of, for example, a conductive material such as metal and is used for conducting electricity. As one of the necessary electronic components of electrical equipment, the electrical connector 1 is often used in chargers.

[0031] Specifically, the support portion 412 has a front region 4124 and a connection region 4121 connected in sequence in the first direction. The contact portion 411 is connected to the connection region 4121. The fixing portion 420 is connected to a side of the contact portion 411 away from the front region 4124, such as a side of the connection region 4121 away from the front region 4124. The first direction is, for example, Figure 1 The length direction of the support portion 412 is shown. The contact portion 411 is arranged in the connection area 4121 of the electrical connector 1, and is not limited to the edge of the connection area 4121. When the support portion 412 is subjected to the elastic force, the connection area 4121 deforms less than the front area 4124 along the elastic force direction, and the closer the contact portion 411 is arranged to the fixing portion 420, the smaller the deformation under the elastic force; the front area 4124 forming the free end interferes with other components in the electronic device, further hindering the deformation of the support portion 412, so that the electrical connector 1 has better pressure resistance and durability, can withstand greater pressure, is not easy to deform or damage, can greatly reduce the occurrence of poor contact problems, and improve the life of electronic components.

[0032] Further, see Figures 1 to 6, the support portion 412 has a front area 4124, a connection area 4121 and a rear area 4125 connected in sequence in the first direction. The support portion 412 has two ends in its length direction, the front area 4124 and the rear area 4125 are respectively arranged near the two ends of the support portion 412, and the connection area 4121 is the middle area. The rear area 4125 is arranged on the contact portion 411 so that the electrical connector 1 is more adapted to the layout of other structures in the electronic device, and it can also interfere with other components in the electronic device, further hindering the deformation of the support portion 412. The fixing portion 420 is connected to the rear area 4125 so that the front area 4124 forms a free end, and the fixing portion 420 is used to connect with an external device (such as a shell or cover of a charger, etc.) to ensure the stability of the electrical connector 1 in the working process. Specifically, the fixing portion 420 can be connected to each side of the rear area 4125, and the specific position of the fixing portion 420 can be adjusted according to user needs and the charger structure, which is not limited here. Specifically, the support portion 412 has a first side 4123 in the first direction, and the contact portion 411 is connected to the first side 4123. The contact portion 411 is, for example, Figure 1 As shown, it is in the shape of a "hook" and has elasticity, and the back side of the support portion 412 away from the contact portion 411 is in contact with an external device (such as a cover or shell of a charger, etc.). The contact portion 411 includes, for example, a bending surface 4112 and a contact surface 4111. One end of the bending surface 4112 is connected to the contact surface 4111, and the other end of the bending surface 4112 is connected to the first side 4123. The bending surface 4112 is elastic, and the bending surface 4112 is, for example, integrally formed with the contact surface 4111. The contact surface 4111 is used to contact an external electronic component to achieve electrical conduction. With the support portion 412 as Figure 1 Taking the rectangular block shown as an example, the first side 4123 is, for example, the side surface of the rectangular block, and the contact portion 411 is arranged on the first side 4123, which is conducive to the elastic deformation of the bending surface 4112 of the contact portion 411 during the rotation of the electrical connector 1 relative to an external device (such as a cover body, etc.), and will deform under the action of force. Since the contact surface 4111 connected to the bending surface 4112 is arranged in the connection area 4121 of the support portion 412 and is connected to the first side 4123, the contact surface 4111 of the contact portion 411 can better withstand external pressure and torque. When the electrical connector 1 rotates relative to the external device, the contact portion 411 will be oppressed by external pressure, and due to the support of the support portion 412, the contact portion 411 will make corresponding elastic deformation without breaking or breaking.

[0033] Further, refer to Figure 1 and Figure 2, the connection area 4121 is provided with a groove 4122 on the first side 4123, and the contact part 411 is arranged in the groove 4122, and a gap is formed with the side wall of the groove 4122. The groove 4122 is used to make the contact part 411 more easily deformed. During operation, taking the electrical connector 1 arranged in the charger as an example, when the charger is plugged into the power socket, the charger contacts the electrode of the socket. Due to the presence of the groove 4122, the contact part 411 is more likely to deform under the action of force, and a gap is formed between the contact part 411 and the side wall of the groove 4122. The presence of the gap allows a certain amount of slack space on both sides of the contact part 411, making the contact part 411 more likely to deform, and the support part 412 is not easy to break. By providing the groove 4122, the contact part 411 can be more flexibly deformed when subjected to force, so as to improve the elastic performance of the contact part 411 and ensure good electrical connection.

[0034] Reference Figure 1 and Figure 2 , the fixing portion 420 includes, for example, a clamping portion 421 and a connecting portion 422, and the connecting portion 422 is respectively connected to the clamping portion 421 and the supporting portion 412. The clamping portion 421 is used to clamp external electrical components, and introduce the AC power transmitted by the power pin 300 into the electrical components through the electrical connector 1 to provide power for the electrical components. When the electrical connector 1 needs to be connected to the circuit board, a corresponding plug-in position can be set on the circuit board, and then the clip-shaped clamping portion 421 can be plugged into the plug-in position to form an electrical connection to quickly assemble the charger. At the same time, since the clip-shaped clamping portion 421 has an outward-warping structure, plugging is easier, and no welding tools are required, which reduces the difficulty of operation and the error rate. Specifically, when assembling the charger, a corresponding plug-in position is set on the circuit board, and an electrical connection is formed by plugging the plug-in position with the clamping portion 421. Compared with the traditional method of soldering the connecting wire, it is convenient for the rapid assembly of the charger. The connecting portion 422 is, for example, Figure 1 The through hole shown cooperates with the positioning column provided on the external device (such as the cover body) for the corresponding through hole to fix the electrical connector 1 on the external device. In other embodiments, the connecting portion 422 may also be, for example, a positioning column, which cooperates with the positioning hole provided on the external device (such as the cover body) for the corresponding positioning column to fix the electrical connector 1 on the external device. This is not limited here.

[0035] Reference Figure 3 and Figure 4 This embodiment also provides a charger 10, which includes a cover 600, a rotating member 200, a power connection pin 300 and the aforementioned electrical connector 1. Figure 7 , Figure 8 and Fig. 9The charger 10 also includes, for example, a housing 500, a circuit board 700, and a transformer 800. The charger 10 also includes, for example, an interface, etc. The interface is provided on the housing 500, and the interface is used to connect the charger to an external device. In order to facilitate the carrying and storage of the charger, the charger 10 is, for example, configured as a foldable plug. The charger 10 provided in this embodiment can be connected to an electronic device via a data cable, and the electronic device is, for example, a mobile phone, a tablet computer, a power bank, etc., and these electronic products are usually connected to the charger 10 to input a stable voltage and current when charging.

[0036] Specifically, the rotating member 200 is movably connected to the cover body 600, and the rotating member 200 is provided with a contact terminal 210. The power pin 300 is connected to the rotating member 200 and electrically connected to the contact terminal 210, and the power pin 300 can rotate relative to the cover body 600. The electrical connector 1 is provided on the cover body 600, and the contact portion 411 is elastically connected to the contact terminal 210. The power pin 300 is, for example, sleeved on both ends of the rotating member 200 and electrically connected to the electrical connector 1, and the power pin 300 can rotate relative to the cover body 600. The rotating member 200 is, for example, a rotating shaft made of insulating material, which is used to be rotatably connected to the cover body 600. The rotating member 200 is movably connected to the cover body 600, and the folding and unfolding functions of the charger 10 can be realized. The power pin 300 is, for example, fixedly connected to the rotating member 200, and the power pin 300 is used to be electrically connected to the power socket. The electrical connector 1 is disposed on the cover 600, and the electrical connection pins 300 can rotate relative to the cover 600 to adapt to different socket layouts. The electrical connection pins 300 are made of metal materials such as copper alloy. The electrical connector 1 is made of conductive materials such as metal for conducting electricity.

[0037] In this embodiment, one end of the contact portion 411 abuts against the power pin 300 to achieve electrical connection. In this embodiment, by providing the contact portion 411 in the connection area 4121 of the support portion 412, a better support effect can be achieved and the problem of poor contact can be reduced. During the abutment between the contact portion 411 and the contact terminal 210, the contact portion 411 undergoes elastic deformation. Since the contact portion 411 is provided in the connection area 4121 of the support portion 412, the contact portion 411 is not easily broken. The contact portion 411 is provided in the connection area 4121 or the rear area 4125 of the support portion 412, so that the elasticity of the contact portion 411 is well maintained. The side of the support portion 412 away from the contact portion 411 is fixed to the cover body 600, for example, so that the contact portion 411 is difficult to deviate. If the contact portion 411 is only provided in the front section of the support portion 412, the contact portion 411 will be more easily deformed and more difficult to recover due to uneven force. For example, the contact surface 4111 of the electrical connector 1 will abut against the contact terminal 210 to achieve electrical connection. In the process of contact between the contact terminal 210 and the electrical connector 1, the bending surface 4112 of the contact portion 411 will undergo elastic deformation, that is, the contact portion 411 will deform under the action of force. Since the contact portion 411 is arranged in the connection area 4121 of the support portion 412, the contact portion 411 can better withstand external pressure and torque. The contact portion 411 will be oppressed by external pressure, and due to the support of the support portion 412, the contact portion 411 will make corresponding elastic deformation without breaking or breaking. In this way, the contact portion 411 has better pressure resistance and durability during use, can withstand greater pressure, is not easy to deform or damage, can greatly reduce the occurrence of poor contact problems, and ensure the reliability and stability of the charger 10.

[0038] When it is necessary to connect an external electrical component such as a circuit board 700 to the electrical connector 1, the clamping portion 421 of the electrical connector 1 can clamp the circuit board 700. Compared with the traditional welding method, this technical means does not require welding operations, saving assembly time and costs, while also reducing problems such as poor contact caused by welding, ensuring the stability of the connection, and improving the reliability and quality of the product. For example, assuming that a product needs to be powered by a charger 10, the traditional connection method requires soldering the connecting wire to the circuit board, which requires professional technicians and tools to operate, and is prone to welding problems. According to the setting method of this embodiment, it is only necessary to set the corresponding plug-in position on the circuit board 700, and then plug the clamp-shaped clamping portion 421 to complete the electrical connection without welding. In this way, not only assembly time and cost are saved, but also the difficulty of operation and error rate are reduced, and production efficiency and quality are improved.

[0039] Reference Figure 5 and Figure 6The fixing portion 420 is, for example, connected to the rear region 4125, and a first limiting portion 610 is provided on the cover body 600 corresponding to the front region 4124, and the front region 4124 is connected with the first limiting portion 610 in cooperation. The front region 4124 is connected with the first limiting portion 610 to prevent the front region 4124 from deforming under the elastic force, so that the contact portion 411 and the contact terminal 210 are in poor contact. Furthermore, a second limiting portion 620 is provided on the cover body 600 corresponding to the rear region 4125, and the rear region 4125 is connected with the second limiting portion 620 in cooperation. The rear region 4125 and the second limiting portion 620 further limit the support portion 412. The first limiting portion 610 and the second limiting portion 620 need to be located on the same straight line so that the electrical connector 1 will not deform. Since the first limiting portion 610 and the second limiting portion 620 limit the front region 4124 and the rear region 4125 of the support portion 412, the support portion 412 will not deform relative to the fixing portion 420. The first limiting portion 610 and the second limiting portion 620 can be Figure 4 The illustrated positioning column designed according to the shape of the electrical connector 1, the front area 4124 is connected with the first limiting portion 610, and the rear area 4125 is connected with the second limiting portion 620, so as to firmly fix the electrical connector 1 on the cover 600, and ensure that the electrical connector 1 will not shake or separate from the cover 600 during the folding and unfolding of the charger 10, so as to avoid poor contact and further improve the stability and reliability of the charger 10. In other embodiments, the first limiting portion 610 and the second limiting portion 620 can also be limiting rings or limiting grooves, etc., and their specific shapes and structures can be designed according to the needs of users and the actual structure of the product, and will not be described in detail here.

[0040] Reference Figure 5 and Figure 6 , the contact surface 4111 is, for example, elastically connected to the contact terminal 210. The contact terminal 210 is, for example, integrally formed with the power pin 300, and the contact terminal 210 abuts against the contact surface 4111 to electrically connect the power pin 300 to the electrical connector 1, and the contact surface 4111 is disposed between the contact terminal 210 and the support portion 412. The contact terminal 210 is, for example, made of a conductive material, and is used to electrically connect the power pin 300 to the electrical connector 1. In this embodiment, the contact terminal 210 is, for example, disposed on the axis of the rotating member 200, and the contact terminal 210 is synchronously driven to rotate relative to the first end 410 as the power pin 300 is unfolded or folded, and since the contact terminal 210 is located on the axis of the rotating member 200, the movement friction of the contact terminal 210 relative to the first end 410 is rotational friction, and further, the rotational friction causes less wear on the first end 410 and the contact terminal 210 than sliding friction, thereby ensuring the stability and reliability of the foldable charger.

[0041] Specifically, the contact surface 4111 is, for example, disposed between the contact terminal 210 and the bent surface 4112, which can provide a better elastic effect and make the contact terminal 210 and the contact surface 4111 contact more closely. During operation, when the charger 10 is plugged into a power socket, the rotating member 200 rotates so that the contact surface 4111 abuts against the contact terminal 210. Since the contact portion 411 is elastic, it can generate appropriate pressure on the contact terminal 210, thereby ensuring a good electrical connection. The electrical connector 1 establishes an electrical connection with the power pin 300 through the contact terminal 210 and the contact surface 4111. For example, when the electrical connector 1 is inserted into a power socket, the rotating member 200 is unfolded, the contact surface 4111 and the contact terminal 210 are in contact, and an electrical connection is established. Since the side of the support portion 412 away from the contact portion 411 is fixed to the external cover 600 or the shell, for example, when the rotating member 200 rotates, the contact surface 4111 is squeezed by external pressure to squeeze the contact terminal 210, so that the contact surface 4111 and the contact terminal 210 are in close contact. In this way, the looseness of the contact terminal 210 can be reduced, ensuring the stability of the electrical connection and good conductivity, thereby ensuring the normal operation of the equipment.

[0042] Specifically, the contact terminal 210 is a rectangular structure. The contact terminal 210 is, for example, set to a rectangular parallelepiped or a cube shape, that is, the surface of the contact terminal 210 in contact with the electrical connector 1 is set to a rectangle or a square. Compared with the prior art, the contact point on the electrical pin is set to a cylindrical shape, and the surface of the contact point on the electrical pin in contact with the conductive sheet is set to a circle. In this embodiment, the surface of the contact terminal 210 in contact with the electrical connector 1 is set to a rectangle or a square. Compared with the prior art, the contact area between the contact terminal 210 and the contact surface 4111 of the present embodiment is larger, which can increase the contact area between the contact portion 411 and the contact terminal 210, and improve the conductivity performance. In addition, the structure of the contact terminal 210 with a rectangular structure can also more effectively utilize space. Compared with a circular structure with the same diameter, the contact terminal 210 with a rectangular structure has a larger area. Therefore, the use of a rectangular contact terminal 210 can provide a larger contact area in a limited space, further improving the reliability of the electrical connection.

[0043] Reference Figure 8 The charger 10 further includes a support member 100, for example, which is disposed on a side of the rotating member 200 away from the cover 600, and is used to fix and support other components. The support member 100 is connected to the cover 600, and a receiving space is formed between the support member 100 and the cover 600. The rotating member 200 is disposed in the receiving space, and the electrical connector 1 is connected to the cover 600 or the support member 100. The support member 100 cooperates with the cover 600 to form a receiving space, so that the rotating member 200 can be fixed, thereby improving the reliability of the charger 10.

[0044] In a preferred embodiment, reference Figure 5 The rotating member 200 is provided with a damping portion 220, for example, Fig. 9 , for example, an elastic part 110 is provided on the support member 100, and one end of the elastic part 110 away from the support member 100 contacts the damping part 220. One end of the elastic part 110 is integrally formed with the support member 100, and the other end is in contact with the damping part 220. The damping part 220 is, for example, a protrusion or a depression, and the elastic part 110 is, for example, provided on the motion track of the rotating member 200 on the support member 100, and is used to cooperate with the damping part 220 to form a damping for the rotation of the rotating member 200. That is, it is prevented that the power pin 300 will rotate freely relative to the support member 100 after being unfolded relative to the support member 100, thereby making it inconvenient for the charger 10 to be inserted into the socket. Specifically, when the power pin 300 is driven to unfold relative to the support member 100, the rotating member 200 is driven to rotate, and when the rotating member 200 rotates, the damping part 220 is driven to rotate. When the power pin 300 is unfolded, the damping part 220 overcomes the resistance of the elastic part 110 and moves from one side of the elastic part 110 to the other side, thereby forming the positioning of the power pin 300 after unfolding.

[0045] Specifically, the housing 500 is made of plastic, for example, to protect the internal electronic components and provide mechanical support. The circuit board 700 is, for example, disposed in the housing 500. The electrical connector 1 is, for example, disposed in the housing 500, and the electrical connector 1 is electrically connected to the circuit board 700.

[0046] Specifically, the housing 500 is provided with an electric control component, which may include components such as a circuit board 700 and a transformer 800, wherein the control chip on the circuit board 700 generates heat when working, and the control chip is a heat generating chip. The transformer 800 is electrically connected to the control circuit board 700 to realize voltage conversion, wherein the transformer and the control chip generate a large amount of heat when working, and are the main heating areas. The electric control component is used to realize the charging function of the charger, and the electric control component generates heat when working. The cover 600 is made of an insulating material with good thermal conductivity, and the thermal conductive structure is made of materials such as polycarbonate resin, graphite, phosphorus-containing flame retardant, etc., which has the functions of fast thermal conductivity and insulation, and can avoid internal leakage problems, thereby improving the heat dissipation effect while ensuring safety. The electric control component is, for example, arranged in the housing 500, and the cover 600 is connected to the housing 500. When the electric control component is working, the heat generated by the electric control component is dissipated through the housing 500 and the cover 600, and the heat dissipation effect is good. In this embodiment, a cover body 600 is provided on the shell 500 of the charger 10. The electronic control components provided in the shell 500 will generate heat when working. A heat dissipation material component is provided on the cover body 600 connected to the electronic control components to help dissipate heat, thereby solving the problem of uneven heat conduction and poor heat dissipation effect of the charger 10.

[0047] As can be seen from the above, the above technical features of the utility model can have one or more of the following beneficial effects: by setting the contact portion 411 on the connection area 4121 of the support portion 412 of the electrical connector 1, the contact portion 411 undergoes elastic deformation during the rotation of the electrical connector 1 relative to an external device (such as a cover body, etc.), and the contact portion 411 undergoes elastic deformation, that is, the contact portion 411 will deform under the action of force. Since the contact portion 411 is set in the connection area 4121 of the support portion 412, the contact portion 411 can better withstand external pressure and torque. When the electrical connector 1 rotates relative to the external device, the contact portion 411 will be oppressed by external pressure, and due to the support of the support portion 412, the contact portion 411 will make corresponding elastic deformation without breaking or breaking. In addition, in this embodiment, by setting the fixing portion 420 on the front area 4124 or the rear area 4125 of the support portion 412, the fixing portion 420 fixes the electrical connector 1 to the external device (such as a cover body, etc.), making it more stable during use. In this way, the contact portion 411 has better pressure resistance and durability during use, can withstand greater pressure, is not easily deformed or damaged, can greatly reduce the occurrence of poor contact problems, and ensure the reliability and stability of the electrical connector 1.
