[0002] TECHNICAL FIELD This application relates to the field of connectors, and more particularly to electrical connectors. [Background technology]

[0003] An electronic connector, commonly referred to as an electrical connector, is a conductive device that connects two conductors in a circuit and allows an electrical current or signal to pass from one conductor to the other.

[0004] In the prior art, the conductive unit of the electrical connector often adopts the following two types. One type is a through-hole type conductive unit of a cylindrical electrical connecting device, which adopts a machining method, and the production process is complicated, the cost is high, the current carrying capacity is limited, and the external dimensions of the conductive unit restrict the connector dimensions, which are larger than the connector of a chip type conductive unit of the same standard, and cannot meet the market demands such as high performance, low cost and light weight of the parts. The other type is a chip type conductive unit, which always adopts a mode in which the circlip wraps the lead, and after the circlip and the lead are fixed, the conductive unit can only be fitted to the electrical connecting device from a single angle, which reduces the utilization rate of the conductive unit and is disadvantageous for mass production of the conductive unit.

As a result, in the electrical connector according to the present application, the above setting allows the first electrical connection device and / or the second electrical connection device to be fitted to the electrical connector at at least two angles (e.g., 90 degrees and 180 degrees).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, the present application will be described with reference to specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Furthermore, the present application may be implemented or applied in other different specific examples, and various modifications and changes may be made within the scope of protection of the present application.

[0013] Based on the above advantages, in order to make the present application more understandable, preferred embodiments are disclosed below, and the technical solutions of the present application and the effects achieved thereby are described in detail below with reference to the drawings and symbols.

[0014] In order to easily understand the electrical connector provided by the present application, first, the application scene of the electrical connector according to the present application will be described. The electrical connector according to the present application is for connecting two conductors (e.g., electrical connection devices).

[0015] As used herein, the term cantilever beam means that one end of the beam is fixed and the other end of the beam is free.

[0016] As shown in FIGS. 1 to 3, the electrical connector according to the present application includes a housing 1 and a first conductive unit 2. The housing 1 has a first opening 11 for inserting a first electrical connection device 8 and a second opening 12 for inserting a second electrical connection device 9, which are provided at a distance from each other. A first insertion portion 13 is provided on a side wall of the housing 1 facing the first opening 11. The first conductive unit 2 can be electrically connected to the first electrical connection device 8 and / or the second electrical connection device 9, and at least a portion of the first conductive unit 2 is accommodated in the housing 1. When the first electrical connection device 8 or the second electrical connection device 9 is inserted into the housing 1 from the outside of the housing 1 through the first insertion portion 13, the first electrical connection device 8 or the second electrical connection device 9 can be electrically connected to at least a portion of the accommodated first conductive unit 2.

[0017] In the electrical connector according to the present application, the first electrical connection device 8 or the second electrical connection device 9 can be electrically connected to at least a part of the accommodated first conductive units 2 when the first electrical connection device 8 or the second electrical connection device 9 is inserted into the housing 1 from the outside of the housing 1 through the first insertion portion 13 by providing the first insertion portion 13 on the side wall facing the first opening 11 of the housing 1. Therefore, the first electrical connection device 8 and the second electrical connection device 9 can be inserted into the housing 1 from the first opening 11 and the second opening 12, respectively, and electrically connected to the first conductive unit 2, and can also be inserted into the housing 1 from the first insertion portion 13 in the first opening 11 and electrically connected to the first conductive unit 2. Thus, with the above structure, the electrical connector according to the present application can realize that the first electrical connection device 8 and / or the second electrical connection device 9 can be fitted to the electrical connector at at least two different angles.

[0018] Specifically, the housing 1 may have a hollow rectangular parallelepiped structure, and the first insertion portion 13 may be a notch provided in the housing 1. The notch communicates with the first opening 11, and at least a part of the first conductive unit 2 is provided in the housing 1 by, for example, welding, bonding, screw connection, or locking. In actual use, the first electrical connection device 8 and the second electrical connection device 9 can be electrically connected to the first conductive unit 2 of the housing 1 by being inserted into the housing 1 from the first opening 11 and the second opening 12, respectively. Alternatively, the first electrical connection device 8 or the second electrical connection device 9 can be inserted into the housing 1 from the first insertion portion 13 communicating with the first opening 11, so that the first electrical connection device 8 or the second electrical connection device 9 inserted through the first insertion portion 13 can be electrically connected to the first conductive unit 2 in the housing 1.

[0019] 1 and 2, a second insertion portion 14 is further provided on a side wall of the housing 1 facing the first opening 11, and the second insertion portion 14 is provided opposite the first insertion portion 13 along a direction perpendicular to the direction O in which the first electrical connection device 8 or the second electrical connection device 9 is inserted into the first opening 11. Specifically, the second insertion portion 14 may be a notch provided in the housing 1 and communicating with the first opening 11.

[0020] In the present application, a first insertion portion 13 and a second insertion portion 14 communicating with the first opening 11 are provided on the side wall facing the first opening 11 of the housing 1, so that the first electrical connection device 8 or the second electrical connection device 9 can be inserted into the housing 1 from the first opening 11, the second opening 12 or the first insertion portion 13, and can also be inserted into the housing 1 from the second insertion portion 14, thereby enabling electrical connection with the first conductive unit 2 from multiple angles and further increasing the number of mating methods between the first electrical connection device 8 or the second electrical connection device 9 and the electrical connector.

[0021] The material of the housing 1 may be a plastic material or a metal material, may be a material with good conductivity, may be a material with poor conductivity, for example, may be a steel material, or may be a material containing steel. The first inserting part 13 and / or the second inserting part 14 according to the present application can insert the first electrical connecting device 8 and the second electrical connecting device 9 into the housing 1 along the direction O, respectively, while it can also be realized that the first electrical connecting device 8 or the second electrical connecting device 9 can be inserted from the side of the housing 1 as shown in FIG. 5. It is clear that the first electrical connecting device 8 or the second electrical connecting device 9 can be selectively inserted along the diagonal direction P of the housing 1. This further enriches the mating method between the first electrical connecting device 8 or the second electrical connecting device 9 and the electrical connector, while the present application is easier to process, for example, the first inserting part 13 and / or the second inserting part 14 can be formed by simply cutting the end of the first opening 11 of the housing 1 directly.

[0022] In one possible embodiment, the first insertion part 13 or the second insertion part 14 may be a hole, such as a rectangular through hole, formed in a side wall of the housing 1, provided at a position close to the first opening 11 or the second opening 12 of the housing 1. In a specific implementation, the peripheral wall of the hole may restrict the position relative to the first electrical connection device 8 or the second electrical connection device 9. Furthermore, in some embodiments, in order to achieve the effect of waterproofing and dustproofing, a waterproof plate or a dustproof plate may be hingedly connected to the peripheral wall of the first insertion part 13 and / or the second insertion part 14 of the housing 1, and the waterproof plate or the dustproof plate is installed to seal the first insertion part 13 or the second insertion part 14, thereby achieving the effect of waterproofing or dustproofing.

[0023] Furthermore, as shown in FIG. 4, the housing 1 has an attachment port 15 for receiving the first conductive unit 2. With the first conductive unit 2 inserted into the housing 1 through the attachment port 15, the side wall of the housing 1 located at the attachment port 15 can be bent to close the attachment port 15. By providing the attachment port 15, the first conductive unit 2 can be quickly inserted into the housing 1, making the assembly simple and the attachment and detachment easy.

[0024] Specifically, the housing 1呈板状 before being molded and can form a substantially "C"-shaped structure when bent along the width direction Q of the plate. The opening of the "C"-shaped structure is the attachment port 15. When assembling the electrical connector, the first conductive unit 2 can be directly inserted into the housing 1 from the outside of the housing 1 through the attachment port 15, and then the attachment port 15 can be closed.

[0025] In the present application, before being molded, the housing 1 includes a first side 17 and a second side 18 provided opposite to each other along the width direction Q. On one of the first side 17 and the second side 18, for example, by means such as welding, adhesion, or integral press molding, an ant-shaped protrusion 171 is provided. On the other of the first side 17 and the second side 18, an ant groove 181 matching the shape of the protrusion 171 is provided, and the protrusion 171 can be locked with the ant groove 181.

[0026] Furthermore, as shown in FIGS. 11 to 12, the housing 1 further includes a clamp member 16 for applying a pre-tightening force to the first conductive unit 2. By providing the clamp member 16, the first electrical connection device 8 or the second electrical connection device 9 inserted into the housing 1 can be clamped more strongly, ensuring the connection reliability of the electrical connector in a vibration environment.

[0027] In the present application, the clamp member 16 includes at least one first housing elastic arm 161 located in the first opening 11 and at least one second housing elastic arm 162 located in the second opening 12. Among them, the first housing elastic arm 161 includes a first free end 1611 capable of entering the housing 1 and abutting against the first conductive unit 2, and the second housing elastic arm 162 includes a second free end 1622 capable of entering the housing 1 and abutting against the first conductive unit 2.

[0028] Specifically, the first housing elastic arm 161 and the second housing elastic arm 162 may be located on the same side of the housing 1, for example, on the top surface of the housing 1 shown in FIG. 1, or the first housing elastic arm 161 and the second housing elastic arm 162 may be located on different sides of the housing 1, for example, the first housing elastic arm 161 is located on the top surface of the housing 1 and the second housing elastic arm 162 is located on the bottom surface of the housing 1.

[0029] Take for example the first electrical connection device 8 being inserted into the housing 1 through the first opening 11 and electrically connected to the first conductive unit 2, and the second electrical connection device 9 being inserted into the housing 1 through the second opening 12 and electrically connected to the first conductive unit 2. By providing the clamp member 16, as the first electrical connection device 8 is inserted into the first opening 11, the first electrical connection device 8 has a certain thickness, so that as the first electrical connection device 8 is inserted into the first opening 11, the first electrical connection device 8 can move the first conductive unit 2 in the thickness direction H of the housing 1 in a direction approaching the inner wall of the adjacent housing 1, as shown in FIG. 12, and at this time, the first housing elastic arm 161 located at the first opening 11 clamps the first electrical connection device 8, and similarly, the second housing elastic arm 162 clamps the second electrical connection device 9 inserted into the second opening 12 more firmly.

[0030] The range of pressure applied from the first housing elastic arm 161 to the first electrical connecting device 8 is 0.3N to 95N, and the range of pressure applied from the second housing elastic arm 162 to the second electrical connecting device 9 is 0.3N to 95N.

[0031] The applicant conducted a test to verify the influence of the pressure applied from the first housing elastic arm 161 to the first electrical connection device 8 on the contact resistance between the first housing elastic arm 161 and the first electrical connection device 8, or the influence of the pressure applied from the second housing elastic arm 162 to the second electrical connection device 9 on the contact resistance between the second housing elastic arm 162 and the second electrical connection device 9. Taking the pressure applied from the first housing elastic arm 161 to the first electrical connection device 8 as an example, the applicant selected the first housing elastic arm 161 and the first electrical connection device 8 having the same shape and dimensions, and designed the pressures between the first housing elastic arm 161 and the first electrical connection device 8 to be different, thereby observing the contact resistance between the first housing elastic arm 161 and the first electrical connection device 8.

[0032] The contact resistance is detected by using a micro-ohmmeter to measure the resistance at the contact point between the first housing elastic arm 161 and the first electrical connecting device 8, and reading the micro-ohmmeter reading. In this embodiment, the ideal value is a contact resistance of less than 50 μΩ.

[0033] Table 1: Effect of different pressures on contact resistance between the housing elastic arm and the electrical connection device

[0034] [Table 1]

[0035] As can be seen from Table 1, when the pressure between the first housing elastic arm 161 and the first electrical connecting device 8 is less than 0.3N, the coupling force is too small, so the contact resistance between them is higher than the ideal value, which does not meet the requirements. When the pressure between the first housing elastic arm 161 and the first electrical connecting device 8 is more than 95N, the contact resistance is not significantly reduced, and the selection and processing of materials is more difficult. Moreover, if the pressure is too large, it may also damage the first electrical connecting device 8. Therefore, the applicant sets the range of pressure applied from the first housing elastic arm 161 to the first electrical connecting device 8 to 0.3N to 95N, and the range of pressure applied from the second housing elastic arm 162 to the second electrical connecting device 9 to 0.3N to 95N.

[0036] The applicant has found that when the pressure between the first housing elastic arm 161 and the first electrical connecting device 8 is greater than 0.5N, the contact resistance between the first housing elastic arm 161 and the first electrical connecting device 8 is relatively good and tends to decrease quickly. When the pressure between the first housing elastic arm 161 and the first electrical connecting device 8 is less than 50N, the conductive elastic piece is convenient to manufacture, install, and use, and the cost is low. Therefore, the applicant has found that the pressure applied from the first housing elastic arm 161 to the first electrical connecting device 8 is preferably in the range of 0.5N to 50N, and the pressure applied from the second housing elastic arm 162 to the second electrical connecting device 9 is preferably in the range of 0.5N to 50N.

[0037] 5 to 7 and 1, the electrical connector further includes a fixing member 3 for fixing the housing 1 and the first conductive unit 2, and the fixing member 3 is provided between the housing 1 and the first conductive unit 2. The provision of the fixing member 3 not only makes it easy to attach and detach the first conductive unit 2, but also regulates the position of the fixing member 3 relative to the first conductive unit 2.

[0038] 6, in one possible embodiment, the fixing member 3 includes a first fixing part 31 and a first fixing engagement part 32 which are detachably connected to each other. The first fixing part 31 is a first protruding member provided on the first conductive unit 2 by, for example, welding, bonding, screw connection, locking, or integral press molding, and the first fixing engagement part 32 is a first recessed member provided on the housing 1.

[0039] In another possible embodiment, the fixing member 3 includes a first fixing portion 31 and a first fixing fitting portion 32 which are detachably connected to each other. The first fixing portion 31 is a first protruding member provided on the housing 1 by, for example, welding, bonding, screw connection, locking, or integral press molding, and the first fixing fitting portion 32 is a first recessed member opened in the first conductive unit 2.

[0040] By providing the first fixing portion 31 and the first fixing engagement portion 32, the structure is simple and the first conductive unit 2 and the housing 1 can be quickly attached and detached by hand without the use of other tools (e.g., strips or welding rods).

[0041] According to an embodiment of the present application, as shown in Figs. 8 and 9, two first conductive units 2 are provided in a housing 1, and the two first conductive units 2 are provided at an interval along a thickness direction H of the housing 1. By providing two first conductive units 2, the first electrical connection device 8 and the second electrical connection device 9 are sandwiched in both directions. Compared with an electrical connector having only one first conductive unit 2, for example, a chip-type electrical connection device, by providing two first conductive units 2, both sides of the chip-type electrical connection device are in contact with the first conductive unit 2, and the reliability that the electrical connection device is certainly electrically connected to the first conductive unit 2 can be improved.

[0042] 7 to 9, a strip-shaped support portion 4 is connected between two first conductive units 2, and the support portion 4 is located on the same side of the two first conductive units 2. By providing the support portion 4, the processing speed of the first conductive units 2 can be improved; that is, before forming the housing 1, two first conductive units 2 on the same plane are folded in half by the support portion 4, so that the processing of the two first conductive units 2 can be completed simultaneously. In addition, since the support portion 4 is located on the same side of the two upper and lower first conductive units 2, the processing of the two first conductive units 2 is also convenient, and the processing speed is improved. Furthermore, since the support portion 4 is connected to the same side of the two first conductive units 2, each first conductive unit 2 corresponds to a cantilever structure, that is, under the action of external pressure, the two first conductive units 2 can approach each other and deform along the thickness direction H of the housing 1, reducing the volume; further, the two first conductive units 2 can be easily inserted into the housing 1 through the mounting holes 15 and do not interfere with the housing 1.

[0043] In the present application, as shown in FIG. 9 , the first conductive unit 2 includes a plurality of first elastic arms 21 positioned in the first opening 11, and the plurality of first elastic arms 21 are arranged at intervals along a direction Q perpendicular to the direction in which the first electrical connection device 8 or the second electrical connection device 9 is inserted into the first opening, and a first gap 22 exists between every two adjacent first elastic arms 21.

[0044] At least two first elastic arms 21 are spaced apart along a direction Q perpendicular to the direction in which the first electrical connecting device 8 or the second electrical connecting device 9 is inserted into the first opening, thereby saving material and reducing manufacturing costs. Furthermore, since the material is reduced, the contact area with the first electrical connecting device 8 is reduced, and the temperature rise value (also called the temperature threshold) due to contact and the resistance value due to contact can be effectively reduced.

[0045] Specifically, the width of the first gap 22 is 1% to 100% of the width of the first elastic arm 21.

[0046] In order to verify the effect of the spacing distance between adjacent first gaps 22 on the contact resistance of the electrical connector, an electrical connector consisting of a first conductive unit 2 and a housing 1 having the same shape and dimensions, a first electrical connection device 8 and a second electrical connection device 9 having the same shape and dimensions were selected, the electrical connector was connected to the second electrical connection device 9, and the contact resistance between the first electrical connection device 8 and the electrical connector was observed.

[0047] The contact resistance is detected by using a micro-ohmmeter to measure the resistance at the contact point between the first electrical connecting device 8 and the electrical connector, and reading the micro-ohmmeter reading. In this embodiment, the ideal value is a contact resistance of less than 50 μΩ.

[0048] Table 2: Effect of the spacing distance (width) of the first gap 22 on the contact resistance between the first electrical connecting device 8 and the electrical connector structure

[0049] [Table 2]

[0050] As can be seen from Table 2, if the ratio of the spacing distance (width) of first gap 22 to the width of first elastic arm 21 is greater than 100%, the contact resistance is greater than 50 μΩ, which does not meet the requirement. Furthermore, the conventional processing method for electrical connector structures is pressing or cutting, and if the spacing distance (width) of first gap 22 is too narrow, it is difficult to process. For these reasons, the spacing distance (width) of first gap 22 is set to 1% to 100% of the width of first elastic arm 21.

[0051] Furthermore, as shown in Figure 9, each first elastic arm 21 includes a first warped section 211 and a first connection section 212 connected in sequence from the first opening 11 to the second opening 12, and the first warped section 211 is inclined toward the outer edge of the first opening 11.

[0052] By providing the first warped section 211 at an incline toward the outer edge of the first opening 11, the electrical connection device inserted into the housing 1 through the first opening 11 can more easily come into contact with the first conductive unit 2, and the electrical connection device can be more firmly clamped. This improves the connection strength between the electrical connection device and the electrical connector, that is, improves the reliability of the electrical connector in use. In addition, since the first warped section 211 is provided at an incline toward the outer edge of the first opening 11, the contact area between the electrical connection device and the connection point between the first warped section 211 and the first connection section 212 of the first conductive unit 2 is reduced, that is, the force-receiving area of ​​the electrical connection device is reduced. During use, the stronger the pressure acting effect on the electrical connection device, the stronger the clamping of the electrical connection device. When the electrical connection device is inserted, the force with which the electrical connection device is inserted is alleviated, the force with which the electrical connection device is inserted is dispersed, and an appropriate insertion force is maintained, that is, the electrical connection device can be inserted more easily.

[0053] 9, the first conductive unit 2 further includes a plurality of second elastic arms 24 located in the second opening 12, the plurality of second elastic arms 24 being spaced apart along a direction Q perpendicular to the direction in which the first electrical connecting device 8 or the second electrical connecting device 9 is inserted into the second opening 12, and a second gap 25 exists between every two adjacent second elastic arms 24. Among them, the plurality of second elastic arms 24 are connected to the plurality of first elastic arms 21 via the first terminal body 23.

[0054] The present application saves material and reduces manufacturing costs by providing at least a plurality of second elastic arms 24 spaced apart along a direction Q perpendicular to the direction in which the first electrical connecting device 8 or the second electrical connecting device 9 is inserted into the second opening 12. Furthermore, since the material is reduced, the contact area with the second electrical connecting device 9 is reduced, which can effectively reduce the temperature rise value (also called temperature threshold) due to contact and the resistance value due to contact.

[0055] In one embodiment, the width of the second gap 25 is 1% to 100% of the width of the second elastic arm 24.

[0056] In order to verify the effect of the spacing distance (width) of adjacent second gaps 25 on the contact resistance of the electrical connector, an electrical connector consisting of a first conductive unit 2 and a housing 1 having the same shape and dimensions, a first electrical connection device 8 and a second electrical connection device 9 having the same shape and dimensions were selected, the electrical connector was connected to the first electrical connection device 8, and the contact resistance between the second electrical connection device 9 and the electrical connector was observed.

[0057] Regarding the method of detecting the contact resistance, a micro-ohmmeter is used to measure the resistance at the contact point between the second electrical connecting device 9 and the electrical connector, and the numerical value of the micro-ohmmeter is read. In this embodiment, the ideal value is a contact resistance of less than 50 μΩ.

[0058] Table 3: Effect of the spacing distance (width) of the second gap 25 on the contact resistance between the second electrical connecting device 9 and the electrical connector structure

[0059] [Table 3]

[0060] As can be seen from Table 3, when the ratio of the spacing distance (width) of the second gap 25 to the width of the second elastic arm 24 is greater than 100%, the contact resistance is greater than 50 μΩ, which does not meet the requirements. Furthermore, the conventional processing method for the electrical connector structure is pressing or cutting, and if the spacing distance (width) of the second gap 25 is too narrow, it becomes difficult to process. For these reasons, the spacing distance (width) of the second gap 25 is set to 1% to 100% of the width of the second elastic arm 24.

[0061] Furthermore, as shown in Figure 9, each second elastic arm 24 includes a second warped section 241 and a second connection section 242 connected in sequence from the second opening 12 to the first opening 11, and the second warped section 241 is arranged at an angle toward the outer edge of the second opening 12.

[0062] By providing the second warped section 241 at an incline toward the outer edge of the second opening 12, the electrical connection device inserted into the housing 1 through the second opening 12 can more easily come into contact with the first conductive unit 2, and the electrical connection device can be more firmly clamped. This improves the connection strength between the electrical connection device and the electrical connector, that is, improves the reliability of the electrical connector in use. In addition, since the first warped section 211 is provided at an incline toward the outer edge of the first opening 11, the contact area between the first conductive unit 2 and the electrical connection device is reduced, that is, the force-receiving area of ​​the electrical connection device is reduced. During use, the pressure acting effect on the electrical connection device is strengthened, and the electrical connection device is clamped more firmly. When the electrical connection device is inserted, the force with which the electrical connection device is inserted is alleviated, the force with which the electrical connection device is inserted is dispersed, and an appropriate insertion force is maintained, that is, the electrical connection device can be inserted more easily.

[0063] In this embodiment, as shown in FIG. 9, the first conductive unit 2 further includes a strip-shaped elastic arm connecting member 26, and a plurality of second connection sections 242 are connected to the inner wall of the housing 1 via the elastic arm connecting member 26.

[0064] The second connection sections 242 are connected to the inner wall of the housing 1 via the elastic arm connecting members 26 to form a plurality of second elastic arms 24 as one unit. This improves the stability of the connection between each of the second elastic arms 24 and the housing 1.

[0065] 7 and 9, according to an embodiment of the present application, the electrical connector further includes a second conductive unit 5 located between the first conductive unit 2 and the housing 1 and removably connected to the first conductive unit 2. The provision of the second conductive unit 5 improves the reliability of the mechanical contact and the electrical connection between the electrical connection device and the electrical connector.

[0066] Furthermore, as shown in Figures 8 and 10, the second conductive unit 5 is provided with a first fixing member 6, and the first conductive unit 2 is provided with a first fixing fitting 7, and the first fixing member 6 can be engaged with and connected to the first fixing fitting 7.

[0067] By providing a first fixing member 6 and a first fixing fitting 7, the present application enables the first conductive unit 2 and the second conductive unit 5 to be quickly attached and detached, has a simple structure, and provides a strong connection.

[0068] 10 , the second conductive unit 5 includes a first elastic reinforcing portion 51 located in the first opening 11. The first elastic reinforcing portion 51 has a plurality of protrusions 511 that can penetrate the first gap 22 along the thickness direction H of the housing 1.

[0069] When two first conductive units 2 are provided in the housing 1, the multiple protrusions 511 of the first elastic reinforcement part 51 can extend between the two first conductive units 2 through the first gap 22 along the thickness direction H of the housing 1, so that when the electrical connection device is inserted into the housing 1 through the first opening 11 or the first insertion part 13, the number of contact points of the electrical connection device increases, and the connection strength with the electrical connector can be further improved, that is, the reliability of the electrical connector connecting with the electrical connection device in use is improved. In addition, by providing the protrusions 511, the contact area between the first conductive unit 2 and the electrical connection device is increased, the distance of current transmission is shortened, and the temperature rise value (also called temperature threshold value) and the contact resistance value are effectively reduced.

[0070] The material of the first conductive unit 2 and the second conductive unit 5 can be copper or a copper alloy, and specifically, may be a tellurium copper alloy, a beryllium copper alloy, a phosphor bronze alloy, a lead brass alloy, or a nickel copper alloy.

[0071] The copper tellurium alloy has good electrical conductivity and ease of cutting, and can ensure electrical properties and improve processability.

[0072] Beryllium copper has high hardness, elastic limit, fatigue limit and wear resistance, and also has good corrosion resistance, thermal conductivity and electrical conductivity, and does not generate sparks when impacted.

[0073] The advantages of phosphorus bronze are that it has better corrosion resistance, wear resistance, can ensure good contact, has good elasticity, and has excellent machining performance, which can quickly reduce the machining time of parts.

[0074] The advantages of lead-brass alloys are high strength, dense and uniform structure, excellent corrosion resistance, and excellent machining performance such as cutting and drilling. Nickel-copper alloys have the characteristics of good corrosion resistance, high hardness, and good ductility, and can reduce the temperature coefficient of electrical resistivity.

[0075] Furthermore, as shown in FIG. 10 , the first elastic reinforcement portion 51 further includes a positive pressure portion 512 that can abut against adjacent first warped sections 211 along the thickness direction H of the housing 1, and the multiple protrusions 511 are provided on the positive pressure portion 512 at intervals along the width direction Q of the housing 1.

[0076] By providing the positive pressure portion 512, a base for mounting each protrusion 511 can be provided. Furthermore, since the positive pressure portion 512 can abut against a plurality of adjacent first warped sections 211 along the thickness direction H of the housing 1, when the electrical connection device is inserted into the housing 1 through the first opening 11, the first insertion portion 13, or the second insertion portion 14 and electrically connected to the first conductive unit 2, the electrical connection device has a certain thickness, so that the first warped section 211 is moved in a direction approaching the inner wall of the adjacent housing 1 along the thickness direction H of the housing 1. By providing the positive pressure portion 512, a positive pressure can be provided to the first warped section 211, so that the first warped section 211 of the first conductive unit 2 is less likely to be curved and deformed, and the clamping force from the first conductive unit 2 to the electrical connection device is improved.

[0077] 10 , the second conductive unit 5 further includes a second elastic reinforcing portion 53 located in the second opening 12, and the second elastic reinforcing portion 53 is connected to the first elastic reinforcing portion 51 via the second terminal body 52. ​​The second elastic reinforcing portion 53 has a plurality of reinforcing arms 531 that penetrate the second gap 25 along the thickness direction H of the housing 1.

[0078] When two first conductive units 2 are provided in the housing 1, the multiple reinforcing arms 531 of the second elastic reinforcing part 53 can extend between the two first conductive units 2 by penetrating the second gap 25 along the thickness direction H of the housing 1, so that when the electrical connection device is inserted between the two first conductive units 2 in the housing 1 through the second opening 12, the number of contact points of the electrical connection device is increased, and the connection strength with the electrical connector can be further improved, that is, the reliability of the electrical connector connecting with the electrical connection device in use is improved. In addition, by providing the multiple reinforcing arms 531 that extend between the two first conductive units 2 by penetrating the second gap 25 along the thickness direction H of the housing 1, the contact area between the first conductive unit 2 and the electrical connection device is increased, the distance of current transmission is shortened, and the temperature rise value (also called temperature threshold value) and the contact resistance value are effectively reduced.

[0079] Furthermore, as shown in FIG. 10, each reinforcing arm 531 includes abutment sections 5311 and contact sections 5312 connected sequentially from the first opening 11 to the second opening 12, and the multiple abutment sections 5311 are capable of abutting against the second elastic arm along the thickness direction H of the housing 1, and the contact sections 5312 penetrate the second gap 25 along the thickness direction H of the housing 1.

[0080] By providing the abutting section 5311, a positive pressure is provided to the second connection section 242. When the electrical connection device is inserted into the housing 1 through the second opening 12 and electrically connected to the first conductive unit 2, the electrical connection device has a certain thickness, so that the second connection section 242 is moved toward the inner wall of the adjacent housing 1 along the thickness direction H of the housing 1. By providing the abutting section 5311, a positive pressure can be provided to the second connection section 242, and deformation such as bending is unlikely to occur in the second connection section 242 of the first conductive unit 2, thereby improving the clamping force from the first conductive unit 2 to the electrical connection device. By providing the contact section 5312, the number of contact points with the electrical connection device at the second opening 12 can be increased, and the connection strength with the electrical connector can be further improved, that is, the reliability of the electrical connector being connected to the electrical connection device in use is improved, and the contact area with the electrical connection device is further increased, the distance of current transmission is shortened, and the temperature rise value (also called temperature threshold value) and the contact resistance value are effectively reduced.
