The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0036] The present disclosure provides a multi-channel elastic terminal, comprising a holding assembly and two arc-shaped bending parts; the holding assembly comprises two holding parts, the two holding parts are arranged in parallel to each other, and a deformation interval is formed between the two holding parts; two ends of each of the holding parts respectively extend a first bending elastic arm and a second bending elastic arm, and the first bending elastic arm and the second bending elastic arm both extend towards the deformation interval; the two arc-shaped bending parts are a first arc-shaped bending part and a second arc-shaped bending part respectively; the first arc-shaped bending part is arranged on one side of the holding assembly, and two ends of the first arc-shaped bending part are connected to the first bending elastic arms of the two holding parts respectively; the second arc-shaped bending part is arranged on the other side of the holding assembly, and two ends of the second arc-shaped bending part are connected to the second bending elastic arms of the two holding parts respectively.

[0037] The aforementioned multi-channel elastic terminal, with its two retaining portions arranged parallel to each other, forms a deformation zone between them.

Furthermore, the first arc-shaped bend is located on one side of the retaining assembly, with its two ends connected to the first bent elastic arms of the two retaining portions.

[0039] like Figures 1 to 4 As shown, in one embodiment, the connection assembly 10 includes a first electrical connection plate 100, a second electrical connection plate 200, and a connector 300. The connector 300 includes a mounting base 310 and a multi-channel resilient terminal 320. The mounting base 310 has a first fixing groove 302, a receiving groove 304, and a second fixing groove 306 that are sequentially connected. The first electrical connection plate 100 and the second electrical connection plate 200 are respectively located on both sides of the mounting base 310.

[0040] In one embodiment, the multi-channel elastic terminal 320 includes a retaining component 322 and two arc-shaped bending portions 324. The retaining component 322 includes two retaining portions 3222, which are arranged parallel to each other and form a deformation interval 3223 between them. Two bent elastic arms 3224 extend from both ends of each retaining portion 3222, namely a first bent elastic arm 3224a and a second bent elastic arm 3224b, both of which extend toward the deformation interval 3223. When the first bent elastic arm 3224a undergoes elastic deformation, it deforms within the space of the deformation interval 3223. Similarly, when the second bent elastic arm 3224b undergoes elastic deformation, it deforms within the space of the deformation interval 3223.

[0041] In one of the embodiments, the two arc-shaped bending portions 324 are a first arc-shaped bending portion 324a and a second arc-shaped bending portion 324b. The first arc-shaped bending portion 324a is arranged on one side of the holding assembly 322, and two ends of the first arc-shaped bending portion 324a are connected to the first bending elastic arms 3224a of the two holding portions 3222 respectively. The second arc-shaped bending portion 324b is arranged on the other side of the holding assembly 322, and two ends of the second arc-shaped bending portion 324b are connected to the second bending elastic arms 3224b of the two holding portions 3222 respectively.

[0042] In one of the embodiments, the two holding portions 3222 are clamped in the first fixing groove 302 and the second fixing groove 306 respectively; and the first bending elastic arm 3224a and the second bending elastic arm 3224b are located in the accommodating groove 304. The first arc-shaped bending portion 324a and the second arc-shaped bending portion 324b protrude from the two sides of the fixing seat 310. Meanwhile, referring to FIG. 1 and FIG. 2, the first electric connection plate 100 is provided with a first conductive sheet 102, and the first arc-shaped bending portion 324a abuts against the first conductive sheet 102. The second electric connection plate 200 is provided with a second conductive sheet 202, and the second arc-shaped bending portion 324b abuts against the second conductive sheet 202. Figure 5

[0043] ​The multi-channel elastic terminal 320, the connector 300 and the connecting assembly 10 have the following advantages. The two holding portions 3222 are arranged in parallel to each other, and the deformation interval 3223 is formed between the two holding portions 3222. The first bending elastic arm 3224a and the second bending elastic arm 3224b are respectively extended from two ends of each of the holding portions 3222, and the first bending elastic arm 3224a and the second bending elastic arm 3224b are both extended towards the deformation interval 3223. The first arc-shaped bending portion 324a is arranged on one side of the holding assembly 322, and the two ends of the first arc-shaped bending portion 324a are connected to the first bending elastic arms 3224a of the two holding portions 3222. The second arc-shaped bending portion 324b is arranged on the other side of the holding assembly 322, and the two ends of the second arc-shaped bending portion 324b are connected to the second bending elastic arms 3224b of the two holding portions 3222. Therefore, the multi-channel elastic terminal 320 can realize double-channel signal transmission. The first bending elastic arms 3224a of the two holding portions 3222 are respectively connected to the two ends of the first arc-shaped bending portion 324a, and the second bending elastic arms 3224b of the two holding portions 3222 are respectively connected to the two ends of the second arc-shaped bending portion 324b. Therefore, the holding assembly 322 is elastically connected to the first arc-shaped bending portion 324a and the second arc-shaped bending portion 324b, and the multi-channel elastic terminal 320 has good elastic strength. The multi-channel elastic terminal 320 provides mutual matching forward force. The first arc-shaped bending portion 324a is elastically abutted to the first conductive sheet 102, and the second arc-shaped bending portion 324b is elastically abutted to the second conductive sheet 202. Therefore, the connector 300 can be reliably and signal-interconnected between the first electric connecting plate 100 and the second electric connecting plate 200.

[0044] As shown in Figure 2 In one embodiment, the multi-channel elastic terminal 320 can realize low-height design of the connector, and can be applied to a connector with smaller terminal spacing. In this embodiment, the terminal spacing of the multi-channel elastic terminal 320 in the direction parallel to the Y axis is smaller than that of a conventional terminal. More channels for signal transmission can be arranged in a fixed seat with the same area. That is, the structure of the connector using the multi-channel elastic terminal of the present application is more compact, and the structural compactness of the connecting assembly 10 is greatly improved.

[0045] Further, the first bending elastic arm 3224a and the second bending elastic arm 3224b are bent towards each other, and the first bending elastic arm 3224a and the second bending elastic arm 3224b are both located in the deformation interval. Therefore, the structure of the multi-channel elastic terminal 320 is more compact.

[0046] Further, the first bending elastic arm 3224a and the second bending elastic arm 3224b are arranged in a staggered manner, i.e., the first bending elastic arm 3224a and the second bending elastic arm 3224b are arranged in a staggered manner along the direction parallel to the X axis, so as to avoid mutual interference of the first bending elastic arm 3224a and the second bending elastic arm 3224b in the process of elastic deformation, improve the use reliability of the multi-channel elastic terminal 320, and meanwhile make the structure of the multi-channel elastic terminal 320 more compact.

[0047] As shown in Figure 4 one of the embodiments, each of the bending elastic arms 3224 comprises a first straight segment 32242, a bending segment 32244 and a second straight segment 32246 connected in sequence, the first straight segment 32242 is connected to one end of the corresponding holding part 3222, and the second straight segment 32246 is connected to one end of the corresponding arc-shaped bending part 324, so that each of the bending elastic arms 3224 has better elasticity, and further so that the multi-channel elastic terminal 320 is elastically abutted on the first conductive sheet 102 and the second conductive sheet 202 respectively. Further, the width of the first straight segment 32242 and the width of the second straight segment 32246 are both smaller than the width of the bending segment 32244, i.e., the width of the first straight segment 32242 in the direction parallel to the Y axis is smaller than the width of the bending segment 32244 in the direction parallel to the Y axis, and the width of the second straight segment 32246 in the direction parallel to the Y axis is smaller than the width of the bending segment 32244 in the direction parallel to the Y axis. Since the bending segment 32244 bears greater bending stress when the bending elastic arm 3224 is elastically deformed, the width of the first straight segment 32242 and the width of the second straight segment 32246 are both smaller than the width of the bending segment 32244, so that the bending segment 32244 has greater bending stress strength, and the reliability and service life of the bending elastic arm 3224 are improved.

[0048] As shown in Figure 4 one of the embodiments, the angle θ1 between the extension direction a of the first straight segment 32242 and the plane where the holding part 3222 is located is 100°-170°, so that the bending elastic arm 3224 has better elasticity. In this embodiment, the angle θ1 between the extension direction a of the first straight segment 32242 and the plane where the holding part 3222 is located is 150°.

[0049] As shown in Figure 4 one of the embodiments, the angle θ2 between the extension direction b of the second straight segment 32246 and the plane where the holding part 3222 is located is 10°-80°. In this embodiment, the angle θ2 between the extension direction b of the second straight segment 32246 and the plane where the holding part 3222 is located is 60°, so that the bending elastic arm 3224 has better elasticity.

[0050] As shown in Figure 4As shown in the drawings, in one embodiment, the bending section 32244 is in a circular arc shape, so that the bending elastic arm 3224 has better elasticity.

[0051] As shown in the drawings, Figure 4 In one embodiment, the first straight section 32242 is connected to the holding part 3222 in a rounded transition, and the second straight section 32246 is connected to the first arc-shaped bending part 324a in a rounded transition, thereby reducing the stress of the multi-channel elastic terminal 320.

[0052] As shown in the drawings, Figure 2 , Figure 4 and Figure 5 Further, the side of the fixed seat 310 adjacent to the first electric connection plate 100 is provided with a plurality of first limiting protrusions 311, which are arranged along the outer periphery of the fixed seat 310, thereby avoiding the problem of excessive elastic compression of the first arc-shaped bending part 324a, and reliably elastically abutting the first conductive sheet 102.

[0053] As shown in the drawings, Figure 2 and Figure 4 Further, the side of the fixed seat 310 adjacent to the second electric connection plate 200 is provided with a plurality of second limiting protrusions 313, which are arranged along the outer periphery of the fixed seat 310, thereby avoiding the problem of excessive elastic compression of the second arc-shaped bending part 324b, and reliably elastically abutting the second conductive sheet 202.

[0054] As shown in the drawings, Figure 4 In one embodiment, the first arc-shaped bending part 324a includes a first arc-shaped contact sheet 324a2, a first arc-shaped protrusion 324a4 and a second arc-shaped protrusion 324a6 protruding from both ends of the first arc-shaped contact sheet 324a2, and the first arc-shaped protrusion 324a4 and the second arc-shaped protrusion 324a6 are connected to the first bending elastic arm 3224a of the two holding parts 3222, so that the two holding parts 3222 and the first arc-shaped contact sheet 324a2 have better elasticity.

[0055] As shown in the drawings, Figure 4 In one embodiment, the second arc-shaped bending part 324b includes a second arc-shaped contact sheet 324b2, a third arc-shaped protrusion 324b4 and a fourth arc-shaped protrusion 324b6 protruding from both ends of the second arc-shaped contact sheet 324b2, and the third arc-shaped protrusion 324b4 and the fourth arc-shaped protrusion 324b6 are connected to the second bending elastic arm 3224b of the two holding parts 3222, so that the two holding parts 3222 and the second arc-shaped contact sheet 324b2 have better elasticity.

[0056] As shown in Figure 4 one of the embodiments, the first arc-shaped convex rib 324a4 and the second arc-shaped convex rib 324a6 are staggered to avoid the mutual interference of the first bending elastic arms 3224a of the two holding portions 3222 during elastic deformation.

[0057] Further, the width of the first arc-shaped contact sheet 324a2 is greater than the width of the first arc-shaped convex rib 324a4 and the width of the second arc-shaped convex rib 324a6, i.e. the width of the first arc-shaped contact sheet 324a2 along the direction parallel to the Y-axis is greater than the width of the first arc-shaped convex rib 324a4 along the direction parallel to the Y-axis, and the width of the first arc-shaped contact sheet 324a2 along the direction parallel to the Y-axis is greater than the width of the second arc-shaped convex rib 324a6 along the direction parallel to the Y-axis, so that the first arc-shaped contact sheet 324a2 has better elastic strength and can better realize the staggered arrangement of the first arc-shaped convex rib 324a4 and the second arc-shaped convex rib 324a6.

[0058] Further, the width of the second arc-shaped contact sheet 324b2 is greater than the width of the third arc-shaped convex rib 324b4 and the width of the fourth arc-shaped convex rib 324b6, i.e. the width of the second arc-shaped contact sheet 324b2 along the direction parallel to the Y-axis is greater than the width of the third arc-shaped convex rib 324b4 along the direction parallel to the Y-axis, and the width of the second arc-shaped contact sheet 324b2 along the direction parallel to the Y-axis is greater than the width of the fourth arc-shaped convex rib 324b6 along the direction parallel to the Y-axis, so that the second arc-shaped contact sheet 324b2 has better elastic strength and can better realize the staggered arrangement of the width of the third arc-shaped convex rib 324b4 and the width of the fourth arc-shaped convex rib 324b6.

[0059] As shown in Figure 4 one of the embodiments, the multi-channel elastic terminal 320 is an integral molding structure, so that the structure of the multi-channel elastic terminal 320 is more compact.

[0060] As shown in Figure 4 one of the embodiments, each holding portion 3222 is provided with an extension protrusion 3222b at both ends, and the two bending elastic arms 3224 extend outward away from the corresponding holding portion through the corresponding extension protrusions 3222b, so that the two bending elastic arms 3224 are better connected to the corresponding holding portion 3222, reducing the deformation stress of the two bending elastic arms 3224 connected to the corresponding holding portion 3222.

[0061] As shown in Figure 4As shown, in one of the embodiments, one of the holding portions 3222 includes two holding units 3222a, one of which is provided with a dovetail groove 32221, and the other of which is provided with a clamping protrusion 32223 clamped in the dovetail groove 32221, so that the two holding units 3222a are firmly connected, and meanwhile, the multi-channel elastic terminal 320 is facilitated to be formed. In this embodiment, one of the holding units 3222a extends out a first bent elastic arm 3224a, and the other of the holding units 3222a extends out a second bent elastic arm 3224b.
