Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a floating terminal with a limiting function. Background Technology

[0002] With the rapid development of the electronics industry, the requirements for connectors are also increasing. When there are deviations in the manufacturing specifications of the connectors, or misalignments in the circuit board installation, the two mating ends of the connectors may not be able to be properly inserted, affecting the production and assembly of electrical products. Currently, floating terminals are commonly used to eliminate manufacturing deviations and installation misalignments, thus solving this problem of inability to properly insert the connectors.

[0003] However, currently, the floating limit of floating terminals is usually achieved through an insulating shell. Since the structure of floating terminals is often complex, the structure of the insulating shell used in conjunction with them becomes overly complex and difficult to design. For example, Chinese patent ZL202323524588.4 provides a terminal for a floating electrical connector, which uses a base to limit the floating of the terminal. The terminal base has an extension portion and a bent portion at both ends, with a clamping portion between them. The bent portion has a positioning portion at its end, and the positioning portion has barbs on its side. As a mating component, the base also has corresponding positioning grooves and other mating structures. The overall design and manufacturing are very difficult. Utility Model Content

[0015] Furthermore, the second abutment extends and connects to the side wall of the floating tank and protrudes toward the interior of the floating tank; the first abutment is disposed on the base; the orthographic projection of the second abutment in the plane of the base at least partially overlaps with the first abutment.

[0016] Furthermore, the Z-axis limiting structure also includes a third abutment portion, which extends and connects to the first abutment portion and protrudes toward the bottom of the floating trough, and can float and abut against the bottom of the floating trough.

[0021] Furthermore, the first axial sidewall has grooves to form multiple spaced elastic ends, and the insertion part includes several clamping pieces that extend and connect to the elastic ends.

[0022] Furthermore, the floating body also includes a second axial sidewall extending and connected to the two ends of the base along the Y-axis. The two second axial sidewalls are bent relative to each other and form a plug-in cavity with the base, the first axial sidewall, and the plug-in portion.

[0043] Please see Figure 1 and Figure 2This application provides a floating terminal with a limiting function, including an outer terminal 10 and an inner terminal 20. The outer terminal 10 is provided with a floating groove 11; the inner terminal 20 is movably disposed within the floating groove 11. The inner terminal 20 includes a floating body 21 and a plug-in portion 22 extending and connected to both ends of the floating body 21. The floating body 21 elastically abuts against the bottom and sidewalls of the floating groove 11. The plug-in portion 22 is disposed at one end of the groove opening of the floating groove 11 and is bent to form a relatively protruding guide surface for clamping the guide-connecting mating terminal. When there is a certain degree of misalignment between the mating terminal and the plug-in portion 22, the mating terminal can provide a pulling force to drive the floating body 21 to float and displace within the floating groove 11, so as to avoid damaging the mating terminal.

[0044] Please see Figure 1-3 Specifically, in some embodiments, the floating body 21 includes a base 211, first axial sidewalls 212 extending and connected to the two ends of the base 211 along the X-axis, and second axial sidewalls 213 extending and connected to the two ends of the base 211 along the Y-axis. The insertion part 22 extends and is connected to the end of the first axial sidewall 212 away from the base 211. The two first axial sidewalls 212 are bent relative to each other, and the two second axial sidewalls 213 are bent relative to each other, forming an insertion cavity with the base 211 and the insertion part 22.

[0045] Furthermore, in some embodiments, the first axial sidewall 212 has a groove 2121 of a certain depth to form a plurality of spaced elastic ends 2122, and the insertion portion 22 includes a plurality of clamping pieces 221, which extend and connect to the elastic ends 2122. This arrangement increases the elastic deformation space of the insertion portion 22, making the clamping pieces 221 more elastic and reducing damage to the mating terminals.

[0046] Furthermore, in some embodiments, the outer terminal 10 is also provided with a fixing part 12 protruding outward for connecting an external plastic part.

[0047] Please see Figure 1 and Figure 4 Furthermore, in some embodiments, the floating terminal with the limiting function further includes a first floating structure 40 for driving the inner terminal 20 to float in the Z-axis direction. Specifically, the first floating structure 40 includes a first elastic arm, one end of which is connected to the bottom of the floating groove 11, and the other end is bent toward the base 211 and elastically abuts against the base 211; or, one end of the first elastic arm is connected to the base 211, and the other end is bent toward the bottom of the floating groove 11 and elastically abuts against the bottom of the floating groove 11. The first floating structure 40, through the elastic support of the first elastic arm, allows the inner terminal 20 to float in the Z-axis direction under force.

[0048] As an example, in this embodiment, one end of the first elastic arm extends and connects to the base 211, and is integrally formed with the inner terminal 20; the other end elastically abuts against the bottom of the floating groove 11, and the inner terminal 20 floats in the Z-axis direction due to the elastic force of the first elastic arm.

[0049] Furthermore, in some embodiments, the floating terminal with limiting function includes a Z-axis limiting structure 30 for limiting the movement of the inner terminal 20 in the Z-axis direction. Specifically, the Z-axis limiting mechanism includes a first abutting portion 31 disposed on the floating body 21 and a second abutting portion 32 disposed on the outer terminal 10. The first abutting portion 31 is disposed below the second abutting portion 32 along the Z-axis direction and can float against the second abutting portion 32 to limit the upward movement of the inner terminal 20 in the Z-axis direction.

[0050] As an example, in this embodiment, the second abutment portion 32 extends and connects to the side wall of the floating tank 11 and protrudes toward the interior of the floating tank 11; the first abutment portion 31 is provided on the base 211; the orthographic projection of the second abutment portion 32 in the plane of the base 211 at least partially overlaps with the first abutment portion 31, so that the inner terminal 20 floats upward along the Z-axis to a certain height, and the first abutment portion 31 and the second abutment portion 32 abut against each other to limit the upward movement of the inner terminal 20 along the Z-axis.

[0051] In some other embodiments, the second abutment portion 32 can be a cutout in the side wall of the floating tank, and the first abutment portion 31 is a hook protruding toward the side wall. The hook is located within the cutout and limits the movement of the inner terminal in the Z-axis direction through the cutout. It is understood that the first abutment portion 31 and the second abutment portion 32 can also be provided as other structures for limiting the Z-axis travel of the inner terminal, which will not be described in detail here.

[0052] Furthermore, in some embodiments, the Z-axis limiting structure 30 further includes a third abutment portion 33, which is rigidly placed between the base 211 and the bottom of the floating tank 11. One end of the third abutment portion 33 is connected to the base 211 or the floating tank 11, and the other end is a free end, which can abut against the bottom of the base 211 or the floating tank 11 when subjected to force.

[0053] As an example, in this embodiment, the third abutment portion 33 is extended and connected to the first abutment portion 31 and protrudes toward the bottom of the floating tank 11. When the inner terminal 20 is subjected to force and moves downward along the Z-axis to a certain position, the third abutment portion 33 rigidly abuts against the bottom of the floating tank 11 to limit the downward movement of the inner terminal 20 along the Z-axis.

[0054] Please see Figure 1 and Figure 5Furthermore, in some embodiments, the floating terminal with limiting function further includes a second floating structure 50 for driving the inner terminal 20 to float in the X-axis direction. Specifically, the second floating structure 50 includes a second elastic arm, one end of which extends and connects to the inner wall of the floating groove 11 opposite to the first axial sidewall 212, and the other end elastically abuts against the first axial sidewall 212; or, one end of the second elastic arm extends and connects to the first axial sidewall 212, and the other end elastically abuts against the inner wall of the floating groove 11 opposite to the first axial sidewall 212. In this configuration, the inner terminal 20 can elastically float in the X-axis direction via the second elastic arm until the first axial sidewall 212 abuts against the inner wall of the floating groove 11 opposite to it.

[0055] As an example, in this embodiment, one end of the second elastic arm extends and connects to the inner wall of the floating tank 11 opposite to the first axial sidewall 212, and is integrally formed with the outer terminal 10. The other end elastically abuts against the first axial sidewall 212. When the inner terminal 20 is subjected to an upward force along the X-axis, it can elastically float between the two inner walls of the floating tank 11 opposite to the first axial sidewall 212 through the second elastic arm.

[0056] Please see Figure 1 , Figure 3 and Figure 6 Furthermore, in some embodiments, the floating terminal with limiting function also includes a third floating structure for driving the inner terminal 20 to float in the Y-axis direction. The third floating structure includes a third elastic arm, one end of which is connected to the inner wall of the floating groove 11 opposite to the second axial sidewall 213, and the other end elastically abuts against the second axial sidewall 213; or, one end of the third elastic arm extends and is connected to the second axial sidewall 213, and the other end elastically abuts against the inner wall of the floating groove 11 opposite to the second axial sidewall 213.

[0057] For example, please refer to Figure 6 In this embodiment, the second axial sidewall 213 is bent to form an elastic contact protruding toward the inner wall of the floating tank 11, which serves as the third elastic arm and elastically abuts against the inner wall of the floating tank 11 opposite to the second axial sidewall 213. This arrangement simplifies the structure of the inner terminal 20 and is beneficial to the production and processing of the inner terminal 20.

[0058] It should be noted that the inner terminal 20 and the outer terminal 10 in the embodiments of this application are both designed as a single piece, which is simple in structure and easy to implement.

[0059] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:

[0060] (1) By designing separate floating inner and outer terminals, the floating terminal itself can be limited to floating position, which makes it more widely applicable;

[0061] (2) By designing a spring-arm type floating structure in the XYZ axis respectively, the inner terminal can float freely inside the outer terminal;

[0062] (3) By setting a Z-axis limiting structure, the movement stroke of the inner terminal in the Z-axis direction is limited;

[0063] (4) Both the inner and outer terminals adopt an integral molding design, which is simple in structure and easy to implement.

[0064] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
