Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0040] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In the description of the present application, the meaning of "a plurality" is two or more, and at least one means one, two or more, unless otherwise specifically defined. Terms such as "first", "second", "third", "fourth", etc. are only used for convenient description to name components or embodiments by numbers, and do not imply an importance ranking between components or embodiments.

[0041] It should also be noted that in the drawings of the specification of the present application, an arrow marked with X indicates the first direction, and an arrow marked with Y indicates the second direction. In the description of the present application, the introduction of the first direction and the second direction is to more clearly define the structure and relative positional relationship of each component in the terminal assembly. In actual implementation, the first direction and the second direction are generally horizontal directions, and the first direction and the second direction intersect each other. Optionally, the first direction and the second direction are perpendicular to each other to optimize the structural layout of the terminal assembly and the connector.

[0042] As a preamble to the embodiments of the present application, the terminal assembly (i.e., the female terminal) has a receiving cavity. By arranging contact elastic pieces in the receiving cavity, the male terminal and the female terminal are electrically connected. To ensure the stability of the connection between the male terminal and the female terminal and the performance of transmitting current, the contact elastic pieces are usually improved so that the contact elastic pieces can not only contact the female terminal and the male terminal firmly, but also be conducive to transmitting current. For example, a cantilever beam is provided on the contact elastic piece. However, the cantilever beam is exposed on the outside, one end is connected to the body of the contact elastic piece, and the other end extends towards the female terminal and abuts against the female terminal. Considering that the structure of the cantilever beam is prone to springback after stamping production, the size is unstable, and the cantilever beam retained on the outside has an insecure structure and is prone to deformation during processing, transportation, and assembly. At the same time, when the male terminal is inserted into the contact elastic piece, after the cantilever beam is deformed by force, the end in contact with the female terminal is prone to accidentally touch and deform the body of the contact elastic piece. Moreover, the cantilever beam is provided on the body of the contact elastic piece, and two are arranged at intervals along the insertion direction of the male terminal. The two cantilever beams are symmetric structures. The split design cannot provide a large enough positive force to contact the female terminal, resulting in poor stability, large contact resistance, long current transmission path, and large volume resistance, all of which are not conducive to transmitting current.

[0043] In view of this, the embodiments of the present application provide a terminal assembly, aiming to solve at least one of the above technical problems.

[0044] Please also combine Figures 1 to 7, a terminal assembly disclosed in an embodiment of the present application includes: a terminal body 10 and a contact elastic piece 20;

[0045] Specifically, the terminal body 10 has a receiving cavity 100, the contact elastic piece 20 is disposed in the receiving cavity 100, the contact elastic piece 20 includes an elastic piece body 201, a first simply supported beam 202 and a second simply supported beam 203. The elastic piece body 201 is formed with an elastic piece receiving cavity 2010 for inserting a male terminal. The first simply supported beam 202 and the second simply supported beam 203 are respectively disposed on two opposite sides of the elastic piece body 201. Both ends of the first simply supported beam 202 are connected to the elastic piece body 201, and the first simply supported beam 202 arches away from the elastic piece body 201 and abuts against the terminal body 10. Both ends of the second simply supported beam 203 are connected to the elastic piece body 201, and the second simply supported beam 203 arches away from the elastic piece body 201 and abuts against the terminal body 10.

[0046] It should be understood that by providing the first simply supported beam 202 and the second simply supported beam 203 with an arched structure, the contact elastic piece 20 has a firm structure, is not easily deformed and is elastic. At the same time, the design of the arched structure, combined with the connection of both ends of the first simply supported beam 202 and the second simply supported beam 203 to the elastic piece body 201, enables the load forces (including the force generated by the male terminal pressing on the elastic piece body 201 and the force generated by the abutment of the first simply supported beam 202 and the second simply supported beam 203 against the terminal body 10) received by the first simply supported beam 202 and the second simply supported beam 203 to be transmitted along the arc paths of the first simply supported beam 202 and the second simply supported beam 203, and can concentrate the load forces on the support points where the first simply supported beam 202 and the second simply supported beam 203 are connected to the elastic piece body 201. This ability to distribute the force enables the first simply supported beam 202 and the second simply supported beam 203 to withstand a large load, improving the stability and safety of the terminal assembly; at the same time, it can cope with the horizontal force received by the contact elastic piece 20 when the male terminal is inserted into the contact elastic piece 20. Secondly, the arched first simply supported beam 202 and the second simply supported beam 203 abut against the terminal body 10, and the arched structure will automatically adjust the shapes of the first simply supported beam 202 and the second simply supported beam to disperse the load and maintain balance, thereby reducing the deformation and stress concentration of the first simply supported beam 202 and the second simply supported beam 203, and avoiding the problem of accidental contact between the first simply supported beam 202 and the second simply supported beam 203 and the elastic piece body 201 after deformation, improving the stability and safety of the contact elastic piece 20.

[0047] In some embodiments, the elastic piece body 201 includes a first support beam 2011 and a second support beam 2012 which are arranged at intervals, and a connecting portion 2013 for connecting the first support beam 2011 and the second support beam 2012. The first support beam 2011, the second support beam 2012 and the connecting portion 2013 enclose an elastic piece cavity 2010. The first support beam 2011 arches towards the direction close to the second support beam 2012, and the second support beam 2012 arches towards the direction close to the first support beam 2011. The first support beam 2011 includes a first abutting portion 20111, and the first abutting portion 20111 is located between the two ends of the first simply supported beam 202. The second support beam 2012 includes a second abutting portion 20121, and the second abutting portion 20121 is located between the two ends of the second simply supported beam 203. Preferably, the first support beam 2011, the second support beam 2012 and the connecting portion 2013 are connected in a U shape, and the first support beam 2011 and the second support beam 2012 are stamped into an arched structure with the middle positions arching towards each other and the two ends moving away from each other. Through the double-arched structure of the first support beam 2011 and the first simply supported beam 202, and the double-arched structure of the second support beam 2012 and the second simply supported beam 203, the contact elastic piece 20 is more elastic and not easily deformed. The contact elastic piece 20 is installed in the terminal body 10, and the upper and lower forces are balanced. A double-arched structure is arranged between one side or both sides of the male terminal and the terminal body 10. Its structure is ingenious and novel. The relative arrangement of the first support beam 2011 and the first simply supported beam 202, and the relative arrangement of the second support beam 2012 and the second simply supported beam 203 enable the force generated by the male terminal pressing on the elastic piece body 201 and the force generated by the first simply supported beam 202 and the second simply supported beam 203 abutting against the terminal body 10 to partially cancel each other, making the structure of the contact elastic piece 20 more reliable. In addition, the double-arched structure can provide sufficient forward force and stable contact resistance, ensuring the stable current transmission ability between the male terminal and the terminal body 10.

[0048] More specifically, the first abutting portion 20111 of the first support beam 2011 is located between the two ends of the first simply supported beam 202; the second abutting portion 20121 of the second support beam 2012 is located between the two ends of the second simply supported beam 203, which can shorten the current transmission path between the male terminal and the terminal body 10. Preferably, the abutting portion of the first support beam 2011 is located at the middle position of the first support beam 2011, the abutting portion of the second support beam 2012 is also located at the middle position of the second support beam 2012, the abutting portion of the first simply supported beam 202 is located at the middle position of the first simply supported beam 202, and the abutting portion of the second simply supported beam 203 is located at the middle position of the second simply supported beam 203. And the above-mentioned abutting positions are spaced along the first direction X. Then, the current transmission path between the male terminal and the terminal body 10 is the sum of the distance from the abutting portion of the first simply supported beam 202 to the connection point of the first simply supported beam 202 and the first support beam 2011 and the distance from the abutting portion of the first support beam 2011 to the connection point of the first simply supported beam 202 and the first support beam 2011. By shortening the current transmission path between the male terminal and the terminal body 10, the resistance value is reduced and the current transmission ability is improved.

[0049] In some embodiments, the first support beam 2011 and the second support beam 2012 are arranged along the first direction X. The first simply supported beam 202 has a third abutting portion 2021 for abutting against the terminal body 10, and the second simply supported beam 203 has a fourth abutting portion 2031 for abutting against the terminal body 10; the first abutting portion 20111 has a first positive projection on the terminal body 10 along the first direction X, and the third abutting portion 2021 has a third positive projection on the terminal body 10 along the first direction X, and the first positive projection is located outside the third positive projection; the second abutting portion 20121 has a second positive projection on the terminal body 10 along the first direction X, and the fourth abutting portion 2031 has a fourth positive projection on the terminal body 10 along the first direction X, and the second positive projection is located outside the fourth positive projection. By arranging the first abutting portion 20111 and the third abutting portion 2021 in a staggered manner and the second abutting portion 20121 and the fourth abutting portion 2031 in a staggered manner, the contact elastic piece 20 is made more elastic, and it is avoided that the connection points between the first support beam 2011 and the first simply supported beam 202 and between the second support beam 2012 and the second simply supported beam 203 are abutted, providing a deformation space for the first support beam 2011, the second support beam 2012, the first simply supported beam 202, and the second simply supported beam 203.

[0050] It should be understood that in some embodiments, the first positive projection of the first abutting portion 20111 on the terminal body 10 along the first direction X and the second positive projection of the second abutting portion 20121 on the terminal body 10 along the first direction X may be directly opposite, may partially overlap, or may even be misaligned; similarly, the third positive projection of the third abutting portion 2021 on the terminal body 10 along the first direction X and the fourth positive projection of the fourth abutting portion 2031 on the terminal body 10 along the first direction X may also be directly opposite, may partially overlap, or may even be misaligned.

[0051] In some embodiments, the first support beam 2011 is provided with a first notch 20110, and the second support beam 2012 is provided with a second notch 20120. Both the first notch 20110 and the second notch 20120 communicate with the elastic piece cavity 2010; the first notch 20110 is correspondingly arranged with the first simply supported beam 202, and the second notch 20120 is correspondingly arranged with the second simply supported beam 203. By providing the first notch 20110 and the second notch 20120, a deformation space is provided for the first support beam 2011, the second support beam 2012, the first simply supported beam 202, and the second simply supported beam 203. At the same time, the arrangement of the first notch 20110 divides the abutting portion of the first support beam 2011 into two parts, and the arrangement of the second notch 20120 divides the abutting portion of the second support beam 2012 into two parts, so that the number of contact points between the male terminal and the terminal body 10 is doubled, the total contact resistance is reduced, and the current transmission capacity is improved.

[0052] It should be understood that the first notch 20110 is correspondingly arranged with the first simply supported beam 202, and the second notch 20120 is correspondingly arranged with the second simply supported beam 203, that is, the projection of the first notch 20110 on the terminal body 10 along the first direction X and the projection of the first simply supported beam 202 on the terminal body 10 along the first direction X are directly opposite. Similarly, the projection of the second notch 20120 on the terminal body 10 along the first direction X and the projection of the second simply supported beam 203 on the terminal body 10 along the first direction X are also directly opposite. After the male terminal is inserted into the elastic piece cavity 2010, a high positive contact force can be generated between the first simply supported beam 202, the second simply supported beam 203 and the terminal body 10, forming an electrical transmission loop between the male terminal and the terminal body 10, shortening the current transmission path and reducing the contact resistance; at the same time, the first simply supported beam 202 and the second simply supported beam 203 can provide the forward and reverse forces of the first support beam 2011 and the second support beam 2012 to contact the male terminal, reducing the contact resistance; at the same time, the double-arch structure is firm and not easily damaged or deformed.

[0053] In some embodiments, the terminal body 10 includes a top plate 101, a bottom plate 102 disposed opposite to each other, and a stop plate 103 connecting the top plate 101 and the bottom plate 102. The top plate 101, the bottom plate 102, and the stop plate 103 enclose a receiving cavity 100; both opposite sides of the elastic piece body 201 are respectively connected to the top plate 101 and the bottom plate 102. It should be understood that the stop plate 103 is at the rear side of the receiving cavity 100 and is used to limit and stop the connecting portion 2013 of the contact elastic piece 20. In some other embodiments, the terminal body 10 further includes a pair of side plates 104 connected to the top plate 101 and the bottom plate 102. The top plate 101, the bottom plate 102, the stop plate 103, and the pair of side plates 104 together enclose the receiving cavity 100. The side wall design can prevent the contact elastic piece 20 from being accidentally touched by foreign objects. Optionally, a dovetail structure 1041 is adopted to connect the side plate 104 and the top plate 101 to ensure the tight fit and fixation between the side plate 104 and the top plate 101.

[0054] In some embodiments, the contact elastic piece 20 further includes a plurality of first protrusions 204 and a plurality of second protrusions 205. The plurality of first protrusions 204 are connected to the elastic piece body 201 and protrude in a direction opposite to the elastic piece body 201 and towards the top plate 101; the plurality of second protrusions 205 are connected to the elastic piece body 201 and protrude in a direction opposite to the elastic piece body 201 and towards the bottom plate 102. By providing protrusions at the positions where the elastic piece body 201 is connected to the top plate 101 and the bottom plate 102, the contact points between the contact elastic piece 20 and the terminal body 10 are increased, and the friction force is increased to form a more stable connection contact.

[0055] In some embodiments, the terminal assembly further includes a housing. The housing is sleeved outside the terminal body 10. Opposite first grooves 1010 and second grooves 1020 are formed on opposite sides of the terminal body 10. The housing is respectively connected to the first groove 1010 and the second groove 1020 through the internal buckles provided. The formation of the first groove 1010 and the second groove 1020 not only satisfies the connection between the housing and the terminal body 10 but also can reduce the material consumption of the terminal body 10.

[0056] In some embodiments, the first simply supported beam 202 has a third abutting portion 2021 that abuts against the terminal body 10, and the second simply supported beam 203 has a fourth abutting portion 2031 that abuts against the terminal body 10; the third abutting portion 2021 corresponds to the first groove 1010, and the fourth abutting portion 2031 corresponds to the second groove 1020. The formation of the first groove 1010 and the second groove 1020 reserves the abutting positions of the first simply supported beam 202 and the second simply supported beam 203 with the terminal body 10, such that the contact areas of the first simply supported beam 202 and the second simply supported beam 203 with the terminal body 10 are large enough. The greater the normal force, the relatively smaller the contact resistance. Moreover, the material removal amount of the terminal body 10 is reduced, the structural strength is high, the volume resistance of the terminal body 10 is small, and the current transmission capacity is improved.

[0057] In some embodiments, the elastic sheet body 201, the first simply supported beam 202, and the second simply supported beam 203 are formed into an integral structure by piercing stamping. Specifically, the elastic sheet body 201 of the contact elastic sheet 20 is stamped into a U-shaped structure, and the opposite sides of the U-shaped structure arch towards each other. By using a local piercing stamping process, the central regions of the opposite sides of the U-shaped structure arch away from each other, so that the elastic sheet body 201, the first simply supported beam 202, and the second simply supported beam 203 are combined into a double-arch structure, realizing the contact connection and current transmission between the male terminal and the terminal body 10. The obtained contact elastic sheet 20 by this processing method does not require material removal, and can improve the utilization rate of materials.

[0058] In some embodiments, the contact elastic sheet 20 has an intersecting first direction X and second direction Y. The first support beam 2011 and the second support beam 2012 are arranged along the first direction X. The first simply supported beam 202 and the second simply supported beam 203 are each provided with a plurality of them at intervals along the second direction Y, and each of the first simply supported beam 202 and the second simply supported beam 203 corresponds to each other along the first direction X. By arranging a plurality of first simply supported beams 202 and a plurality of second simply supported beams 203 at intervals along the second direction Y and adopting a framework structure, the contact elastic sheet 20 is more stably installed in the terminal body 10, the whole is more elastic, and the interval arrangement can well disperse the forces on the first simply supported beam 202 and the second simply supported beam 203, reserving a certain deformation space and having higher safety.
