[0031] In order to better understand the technical scheme and beneficial effects of the application, the application will be further described in detail below in combination with specific embodiments.
[0032] As shown in FIG. 1, the terminal structure comprises a terminal fixing part 1, an elastic bending force arm 2 and a terminal abutting part 3 connected in sequence. Figures 1 to 3As shown, the connector assembly 10 of one embodiment includes an insulating base 100 and a terminal structure 200, which is mounted on the insulating base 100. Referring to Figure 4 Figure 5 In one embodiment, the terminal structure 200 includes a terminal fixing portion 210, an elastic bending force arm 220 and a terminal contact portion 230 connected in sequence, wherein the terminal fixing portion 210 is fixedly connected to the insulating base 100. The elastic bending force arm 220 includes a support portion 222 and a bending portion 224 connected in sequence, the end of the support portion 222 away from the bending portion 224 is connected to the terminal fixing portion 210, and the two ends of the support portion 222 are connected to the bending portion 224 and the terminal fixing portion 210 respectively. The end of the bending portion 224 away from the support portion 222 is connected to the terminal contact portion 230, and the two ends of the bending portion 224 are connected to the support portion 222 and the terminal contact portion 230 respectively, so that the terminal contact portion 230, the bending portion 224, the support portion 222 and the terminal fixing portion 210 are connected in sequence, and the terminal contact portion 230 and the terminal fixing portion 210 are reliably electrically connected.
[0033] As shown in Figure 5 In one embodiment, the support portion 222 is used to abut against the insulating base 100, so that the insulating base 100 supports the elastic bending force arm 220, and thus the elastic bending force arm 220 is relatively stable under pressure, and the entire terminal structure 200 is relatively stable under pressure. The lowermost edge of the contour line of the bending portion 224 and the terminal contact portion 230 are located on the two sides of the plane where the support portion 222 is located, i.e. the bending portion 224 is located on one side of the plane where the support portion 222 is located, and the terminal contact portion 230 is located on the other side of the plane where the support portion 222 is located. Referring to Figure 1 In this embodiment, the terminal fixing portion 210 contacts the first electronic element 20, and the terminal contact portion 230 contacts the second electronic element 30, so that the first electronic element is electrically connected to the second electronic element through the connector assembly 10.
[0034] The terminal structure 200 and the connector assembly 10 have the following advantages. The terminal structure 200 is connected to the elastic bending force arm 220 through the support portion 222 and the bending portion 224, and the terminal fixed portion 210 and the terminal abutting portion 230 are connected to the elastic bending force arm 220, respectively. The terminal structure 200 is supported by the elastic bending force arm 220, so that the terminal structure 200 is reliably installed on the insulating base 100 and is stable under pressure. The bending portion 224 has a smaller structure, and the terminal structure 200 reliably abuts against the electronic component. The connector assembly 10 has a low profile design, and the connector assembly 10 has a smaller size. The bending portion 224 has good damping performance, and the terminal structure 200 is better assembled on the insulating base 100.
[0035] In the embodiment, the bending portion 224 has the same curvature at each position, i.e., the bending portion has an equal-curvature arc structure. The bending portion has good damping performance. It can be understood that in other embodiments, the bending portion is not limited to the equal-curvature arc structure, but can also be a non-equal-curvature arc structure. Further, the bending portion has a maximum curvature, and the terminal abutting portion 230 is located on the other side of the plane on which the support portion 222 is located. The bending portion 224 has a maximum curvature on one side of the plane on which the support portion 222 is located, and the terminal abutting portion 230 is located on the other side of the plane on which the support portion 222 is located. The bending portion 224 is at least partially located on one side of the plane on which the support portion 222 is located, and the terminal abutting portion 230 is located on the other side of the plane on which the support portion 222 is located. The terminal structure 200 has a smaller structure when assembled on the insulating base 100, and the terminal structure 200 reliably abuts against the electronic component. The connector assembly 10 has a low profile design, and the connector assembly 10 has a smaller size. The bending portion has a non-equal-curvature arc structure, and the structure of the bending portion is more ingenious and better adapts to the low profile design.
[0036] In one embodiment, the first electronic component is a printed circuit board, and the second electronic component is a printed circuit board or a CPU. Alternatively, the first electronic component is a printed circuit board or a CPU, and the second electronic component is a printed circuit board. In one embodiment, both the first electronic component and the second electronic component are printed circuit boards. The first electronic component is provided with a first conductive sheet. The terminal fixing portion 210 is in contact with the first conductive sheet, so that the terminal structure 200 is electrically connected to the first electronic component. The second electronic component is provided with a second conductive sheet. The terminal contact portion 230 is in contact with the second conductive sheet, so that the terminal structure 200 is electrically connected to the second electronic component.
[0037] In one embodiment, the first electronic component and the second electronic component are arranged in parallel with the insulating base 100, so that the first electronic component is better electrically connected to the second electronic component through the connector assembly 10. In one embodiment, the terminal contact portion 230 is in the shape of a bend, so that the terminal contact portion 230 is in elastic contact with the second electronic component, and the terminal contact portion 230 is better in contact with the second electronic component.
[0038] As shown in Figure 5 In one embodiment, the lowest edge of the profile line of the bend is below the support portion, so that the deformation at the center of the bend 224 is below the support portion 222. The space occupied by the elastic bending arm 220 is reduced, and the structural volume of the terminal structure 200 assembled in the insulating base 100 is further reduced.
[0039] In order to quickly and reliably fix the terminal fixing portion 210 to the insulating base 100, as shown in Figure 5 In one embodiment, the insulating base 100 is formed with a clamping groove 102. The terminal fixing portion 210 is arranged in the clamping groove 102 and is clamped with the insulating base 100, so that the terminal fixing portion 210 is quickly and reliably fixed to the insulating base 100.
[0040] As shown in Figure 5 and Figure 6As shown, further, the insulating base 100 is formed with a support protrusion 104, the extension direction of the support force of the support protrusion 104 passing through the contact point of the terminal contact portion 230, which contacts the second electronic component. Since the extension direction of the support force of the support protrusion 104 passes through the contact point of the terminal contact portion 230, the extension direction of the support force of the support protrusion 104 passes through the contact point of the terminal contact portion 230 and the second electronic component. When the contact point of the terminal contact portion 230 is pressed, the support portion 222 and the contact point of the terminal contact portion 230 form a self-stable force system, reducing the force between the conductive contact portion 240 and the terminal fixing portion 210, thereby avoiding the problem that the soldered interface of the conductive contact portion 240 and the terminal fixing portion 210 is easily damaged, improving the service life of the connector assembly 10, and avoiding the problem that the terminal structure 200 and the insulating base 100 are shaken due to large force, improving the electrical connection reliability of the terminal structure 200 and the electronic component.
[0041] As shown in Figure 5 and Figure 6 In one embodiment, the insulating base 100 is further formed with a receiving groove 106 communicating with the clamping groove 102, and the support protrusion 104 is formed on the inner wall of the receiving groove 106, so that the insulating base 100 is better abutted and supported on the support portion 222. The elastic bending force arm is received in the receiving groove 106, and the lowermost end of the bending portion 224 of the elastic bending force arm is lower than the support portion 222, so that the insulating base 100 better receives the terminal structure 200. In addition, the lowermost end of the bending portion 224 of the elastic bending force arm is lower than the support portion 222, which maximizes the use of product space, makes the structure of the connector assembly 10 more compact, realizes the low profile of the connector assembly 10, and ensures the excellent mechanical properties of the conductive terminal. In this embodiment, the elastic bending force arm is in a bent shape, which better absorbs vibration, makes the terminal structure 200 have better vibration reduction, and makes the connector assembly 10 easy to realize low profile design. In one embodiment, the connector assembly 10 is an LGA connector.
[0042] As shown in Figure 5 and Figure 6As shown, further, the accommodation groove 106 comprises a deformation limiting groove 1062 and a containing groove 1064, the deformation limiting groove 1062 communicates with the clamping groove 102 through the containing groove 1064, that is, the containing groove 1064 respectively communicates with the deformation limiting groove 1062 and the clamping groove 102, the supporting protrusion 104 is formed between the inner wall of the deformation limiting groove 1062 and the inner wall of the clamping groove 102, so that the insulating base 100 is better abutted and supported on the support portion 222. In the embodiment, the bending portion 224 is located in the deformation limiting groove 1062, so that the bending portion 224 is abutted on the inner wall of the deformation limiting groove 1062 when the bending portion 224 is deformed under pressure, so that the deformation limiting groove 1062 and the supporting surface can abut and support the terminal structure 200, so that the terminal structure 200 is more stable when assembled and connected to the insulating base 100, and the deformation limiting groove 1062 limits the terminal structure 200 from being excessively deformed under pressure, avoiding the problem that the terminal structure 200 is easily damaged by excessive deformation under pressure. Further, the terminal abutting portion 230 protrudes from the insulating base 100, so that the terminal abutting portion 230 better abuts the second electronic element, so that the connector assembly 10 is electrically connected to the second electronic element. Since the supporting protrusion 104 supports the support portion 222, and the bending portion 224 is located in the deformation limiting groove 1062, when the bending portion 224 is deformed greatly, the bending portion 224 is abutted on the inner wall of the deformation limiting groove 1062, so that the inner wall of the deformation limiting groove 1062 supports the bending portion 224, and the terminal fixed portion 210 is connected to the insulating base 100, so that the terminal structure 200 is more stable when under pressure, solving the problem of poor reliability of electrical connection of the connector assembly 10, and the limiting effect of the deformation limiting groove 1062 avoids excessive compression of the terminal, solving the problem that the terminal is easily plastically deformed and broken.
[0043] As shown, Figure 5 Further, the supporting protrusion 104 is provided with a supporting surface 1041, which is a planar structure, so that the supporting surface is better supported on the support portion 222, and the structure of the supporting surface is simpler. It can be understood that in other embodiments, the supporting surface is not limited to a planar structure, but can also be a curved surface structure or other shapes.
[0044] As shown, Figure 5 and Figure 6As shown in the drawings, in one of the embodiments, the surface of the insulating base 100, in which the accommodating groove 1064 is formed, is arranged parallel to the supporting surface. Since the supporting surface is supported by the supporting portion 222, the surface of the insulating base 100, in which the accommodating groove 1064 is formed, is arranged parallel to the supporting surface, so that the terminal structure 200 is assembled to the insulating base 100 and can be reliably in contact with the second electronic element for electrical connection. In the present embodiment, the second electronic element is a printed circuit board, and the second electronic element is arranged parallel to the insulating base 100, i.e., the second electronic element is arranged parallel to the surface of the insulating base 100, in which the accommodating groove 1064 is formed. Since the surface of the insulating base 100, in which the accommodating groove 1064 is formed, is arranged parallel to the supporting surface, the terminal structure 200 can be reliably in contact with the second electronic element for electrical connection.
[0045] As shown in the drawings, Figure 5 and Figure 6 In one of the embodiments, the terminal structure 200 further includes a conductive contact portion 240, which is located on one side of the insulating base 100 and is welded to the terminal fixing portion 210. The elastic bending force arm is located on the other side of the insulating base 100, so that the conductive contact portion 240 is reliably fixedly connected to the terminal fixing portion 210, and the terminal structure 200 is reliably fixedly connected to the insulating base 100. In the present embodiment, the conductive contact portion 240 is located on one side of the insulating base 100 and is in contact with the first electronic element, so that the terminal fixing portion 210 is electrically connected to the first electronic element through the conductive contact portion 240.
[0046] As shown in the drawings, Figure 5 and Figure 6 In one of the embodiments, the terminal fixing portion 210 is formed with a clamping protrusion 212, which is in abutment with the clamping groove 102, so that the terminal fixing portion 210 is clamped and positioned in the clamping groove 102, avoiding the terminal fixing portion 210 from being separated from the side of the insulating base 100, which is away from the second electronic element, so that the terminal fixing portion 210 is reliably fixed to the insulating base 100. In one of the embodiments, the clamping protrusion is an arc-shaped protrusion structure, so that the clamping protrusion is better clamped and positioned in the clamping groove 102. In one of the embodiments, the number of the clamping protrusions is two, and the two clamping protrusions are oppositely arranged on the two sides of the terminal fixing portion 210, so that the terminal fixing portion 210 is better clamped and positioned in the clamping groove 102.
[0047] As shown in the drawings, Figure 6 and Figure 7As shown, further, the terminal fixing portion 210 is also formed with a holding clamping point 214, which is located outside the clamping groove 102, and the terminal fixing portion 210 is welded to the conductive contact portion 240 at the position of the holding clamping point. Since the holding clamping point is located outside the clamping groove 102, i.e. the highest point of the holding clamping point is located on the lower outer surface of the insulating base 100, while fixing the terminal structure 200, the terminal fixing portion 210 is prevented from being separated from the side of the insulating base 100 away from the first electronic component, and internal extrusion stress is not generated due to continuous extrusion of the insulating base 100, thereby reducing internal stress of the entire connector assembly 10 and reducing warping of the connector assembly 10. In one embodiment, the number of the holding clamping points 214 is two, and the two holding clamping points are oppositely arranged on the two sides of the terminal fixing portion 210, which better prevents the terminal fixing portion 210 from being separated from the clamping groove 102.
[0048] As shown in FIG. 1, the terminal structure 200 is arranged on the second electronic component 20, and the terminal structure 200 is arranged in the clamping groove 102 of the insulating base 100. Figure 6 As shown in FIG. 1, the terminal structure 200 is arranged on the second electronic component 20, and the terminal structure 200 is arranged in the clamping groove 102 of the insulating base 100. Figure 7 As shown in FIG. 1, the terminal structure 200 is arranged on the second electronic component 20, and the terminal structure 200 is arranged in the clamping groove 102 of the insulating base 100. In one embodiment, the terminal abutting portion 230 is located above the support portion 222, so that when the terminal structure 200 is abutted and pressed by the second electronic component, a self-stable stress system is formed, and stress between the terminal fixing portion 210 and the insulating base 100 is reduced. In one embodiment, the extension direction of the support force of the support protrusion 104 on the support portion 222 passes through the abutting point of the terminal abutting portion 230, so that the support protrusion 104 better abuts and supports the terminal structure 200. In this embodiment, the terminal abutting portion 230 is located directly above the support portion 222, and when the abutting point of the terminal abutting portion 230 is pressed, the support portion 222 and the abutting point of the terminal abutting portion 230 form a self-stable stress system, which better reduces stress between the conductive contact portion 240 and the terminal fixing portion 210, thereby better preventing the welding interface between the conductive contact portion 240 and the terminal fixing portion 210 from being damaged and improving the service life of the connector assembly 10. At the same time, the problem of shaking of the connection between the terminal structure 200 and the insulating base 100 due to large stress is avoided, and the electrical connection reliability of the terminal structure 200 and the electronic component is improved.
[0049] As shown in FIG. 1, the terminal structure 200 is arranged on the second electronic component 20, and the terminal structure 200 is arranged in the clamping groove 102 of the insulating base 100. Figure 6 As shown in FIG. 1, the terminal structure 200 is arranged on the second electronic component 20, and the terminal structure 200 is arranged in the clamping groove 102 of the insulating base 100. Figure 7As shown in the drawings, in one embodiment, the elastic bending force arm 220 further comprises a connecting portion 226, two ends of the connecting portion 226 are connected with the bending portion 224 and the supporting portion 222 respectively, so that the bending portion 224 is connected with the supporting portion 222 through the connecting portion. Further, the connecting portion 226 extends obliquely towards the side close to the terminal fixing portion 210, the lowermost end of the bending portion 224 is arranged lower than the supporting portion 222, and the lowermost end of the bending portion 224 is arranged lower than the uppermost end of the terminal fixing portion 210. Since the elastic bending force arm is accommodated in the accommodation groove 106, by this design, the product space can be maximized, the structure of the connector assembly 10 is more compact, the low height of the connector assembly 10 is realized, and the excellent mechanical properties of the conductive terminal are ensured. In this embodiment, the elastic bending force arm is in a bent shape, so that the elastic bending force arm can better absorb vibration, the terminal structure 200 has better vibration damping performance, and the low height design of the connector assembly 10 is easy to realize.
[0050] As shown in the drawings, Figure 6 and Figure 7 As shown in the drawings, in one embodiment, the elastic bending force arm 220 further comprises an extension portion 228, two ends of the extension portion are connected with the bending portion 224 and the terminal abutting portion 230 respectively, so that the bending portion 224 is connected with the terminal abutting portion 230 through the extension portion, and the terminal abutting portion 230 has better anti-vibration performance. In one embodiment, the terminal abutting portion 230 protrudes from the surface of the insulating base 100, so that the terminal abutting portion 230 is better in abutting electrical connection with the second electronic element.
[0051] As shown in the drawings, Figure 5 In one embodiment, the inner wall of the deformation limiting groove 1062 is provided with a first guide inclined surface 1063, the first guide inclined surface extends to the supporting surface, so that the bending portion 224 deforms and abuts against the inner wall of the deformation limiting groove 1062 when the terminal structure 200 is deformed under pressure. Since the inner wall of the deformation limiting groove 1062 is provided with the first guide inclined surface, the bending portion 224 is better in adhesion to the surface of the deformation limiting groove 1062 when deformed, the supporting surface is better in abutting support on the supporting portion 222, and the interference of the assembly of the terminal structure 200 on the insulating base 100 is reduced, so that the terminal structure 200 is better in assembly on the insulating base 100.
[0052] As shown in the drawings, Figure 5 In one embodiment, the inner wall of the clamping groove 102 is provided with a second guide inclined surface 1022, the second guide inclined surface extends to the supporting surface, so that the terminal fixing portion 210 can be quickly assembled in the clamping groove 102 through the second guide inclined surface, and the convenience of the assembly of the terminal structure 200 on the insulating base 100 is improved.
[0053] As shown in the drawings, Figure 5As shown in the drawings, in one embodiment, the insulating base 100 is provided with a limiting platform 101 on the surface where the accommodating groove 1064 is formed, so that the limiting platform plays a role of limiting the first electronic component when the first electronic component moves towards the insulating base 100, for example, when the first electronic component moves towards the insulating base 100 due to vibration, the problem that the first electronic component is excessively pressed against the terminal structure 200 to cause a large deformation is avoided, and the situation that the terminal is easily damaged is further solved. In this embodiment, the number of the limiting platforms is multiple, and the multiple limiting platforms are arranged at intervals in the circumferential direction around the opening of the accommodating groove 1064, so as to better limit the first electronic component.
[0054] As shown in the drawings, Figure 7 As shown in the drawings, in one embodiment, the elastic bending arm 220 further comprises a connecting portion 226 and an extension portion 228, two ends of the connecting portion are respectively connected with the bending portion 224 and the supporting portion 222, so that the bending portion 224 is connected with the supporting portion 222 through the connecting portion. Two ends of the extension portion are respectively connected with the bending portion 224 and the terminal abutting portion 230, so that the bending portion 224 is connected with the terminal abutting portion 230 through the extension portion.
[0055] As shown in the drawings, Figure 7 As shown in the drawings, in one embodiment, the terminal fixing portion 210, the supporting portion 222, the connecting portion 226, the bending portion 224, the extension portion 228 and the terminal abutting portion 230 are integrally formed, so that the terminal structure 200 is more compact, and the terminal fixing portion 210, the supporting portion 222, the connecting portion, the bending portion 224, the extension portion and the terminal abutting portion 230 are firmly connected. It can be understood that in other embodiments, the terminal fixing portion 210, the supporting portion 222, the connecting portion, the bending portion 224, the extension portion and the terminal abutting portion 230 can be formed respectively and sequentially fixed and connected by welding.
[0056] As shown in the drawings, Figure 7 As shown in the drawings, in one embodiment, the width D1 of the supporting portion 222 in the direction perpendicular to the extension direction is less than the width D2 of the bending portion 224 in the direction perpendicular to the extension direction, and the width D2 of the bending portion 224 in the direction perpendicular to the extension direction is greater than the width D3 of the terminal abutting portion 230 in the direction perpendicular to the extension direction, so that the width of the terminal abutting portion 230 in the extension direction of the terminal structure 200 is greater than the width of the supporting portion 222, and the width of the terminal abutting portion 230 in the extension direction of the terminal structure 200 is greater than the width of the bending portion 224, so that the bending portion 224 of the terminal structure 200 which has a large deformation under pressure has better bending stress strength, so that the terminal structure 200 has better mechanical properties.
[0057] As shown in the drawings, Figure 7As shown, in one embodiment, the terminal fixing part 210 includes a snap-fit base 211 and an arc-shaped fixing part 213. The snap-fit base 211 snaps onto the insulating base 100, so that the terminal fixing part 210 is quickly and reliably fixed to the insulating base 100. The two ends of the arc-shaped fixing part 213 are respectively connected to the snap-fit base 211 and the support part 222, so that the terminal fixing part 210 is connected to the support part 222.
[0058] like Figure 5 and Figure 6 As shown, in one embodiment, the insulating base 100 also has a mounting groove 105, which communicates with the snap-fit groove 102. See also... Figure 8 The conductive contact 240 is located within the mounting groove 105 and abuts against the insulating base 100, allowing the conductive contact 240 to better abut against the insulating base 100. In one embodiment, the conductive contact 240 is a spherical contact, allowing the conductive contact 240 to better abut against the insulating base 100. In this embodiment, the first electronic component has an abutting curved surface that is adapted to the conductive contact 240, allowing the conductive contact 240 to better abut against the abutting curved surface, thereby allowing the conductive contact 240 to be better electrically connected to the first electronic component.
[0059] like Figure 5 and Figure 6 As shown, in one embodiment, an abutment surface 242 is formed at the connection between the conductive contact 240 and the terminal fixing part 210. The abutment surface 242 abuts against the inner wall of the mounting groove 105, so that the conductive contact 240 abuts against the insulating base 100 better, and at the same time, the terminal structure 200 is assembled more stably on the insulating base 100.
[0060] like Figure 5 and Figure 6As shown in the drawings, in one embodiment, the abutting surface 242 is provided with a clamping hole 2422, and the terminal fixing portion 210 is located in the clamping hole 2422 and is welded with the conductive contact portion 240, so that the conductive contact portion 240 is better fixed and welded with the terminal fixing portion 210, and the connection between the conductive contact portion 240 and the terminal fixing portion 210 is more firm. In one embodiment, the insulating base 100 is formed with a supporting protrusion 104, and the extending direction of the supporting force of the supporting protrusion 104 on the supporting portion 222 passes through the abutting point of the terminal abutting portion 230, and the abutting point abuts against the second electronic element. Since the extending direction of the supporting force of the supporting protrusion 104 on the supporting portion 222 passes through the abutting point of the terminal abutting portion 230, the extending direction of the supporting force of the supporting protrusion 104 on the supporting portion 222 passes through the abutting point of the terminal abutting portion 230 and the second electronic element. When the abutting point of the terminal abutting portion 230 is pressed, the supporting portion 222 and the abutting point of the terminal abutting portion 230 form a self-stabilizing force system, which reduces the force between the conductive contact portion 240 and the terminal fixing portion 210, that is, the force at the welding position of the terminal fixing portion 210 and the conductive contact portion 240, thereby avoiding the problem that the welding interface between the conductive contact portion 240 and the terminal fixing portion 210 is easily damaged, improving the service life of the connector assembly 10, and avoiding the problem that the terminal structure 200 and the insulating base 100 are shaken due to large force, thereby improving the electrical connection reliability of the terminal structure 200 and the electronic element.
[0061] As shown in the drawings, Figure 6 and Figure 7 In one embodiment, the clamping point 214 is located in the clamping hole 2422 and is welded with the conductive contact portion 240, so that the conductive contact portion 240 is better fixed and welded with the terminal fixing portion 210. Since the clamping point is located outside the clamping groove 102, that is, the highest point of the clamping point is located on the lower outer surface of the insulating base 100, when the terminal structure 200 is fixed, the terminal fixing portion 210 cannot be separated from the side of the insulating base 100 away from the first electronic element, and internal extrusion stress cannot be generated due to continuous extrusion of the insulating base 100, thereby reducing the internal stress of the entire connector assembly 10 and reducing the warping of the connector assembly 10.
[0062] Compared with the prior art, the present application has at least the following advantages:
[0063] 1. Since the support part 222 and the bending part 224 are connected, the end of the support part 222 away from the bending part 224 is connected to the terminal fixing part 210, so that the terminal fixing part 210 is connected to the elastic bending arm 220. Since the end of the bending part 224 away from the support part 222 is connected to the terminal contact part 230, so that the terminal contact part 230 is connected to the elastic bending arm 220. Thus, the elastic bending arm 220 is connected to the terminal fixing part 210 and the terminal contact part 230 respectively. With the insulating base 100 supporting the elastic bending arm 220, the terminal structure 200 is subjected to pressure more stably, and the terminal structure 200 is reliably installed on the insulating base 100.
[0064] 2. Since the lowest edge of the outline of the bent portion 224 and the terminal contact portion 230 are located on both sides of the plane where the support portion 222 is located, and the terminal contact portion 230 is located on the other side of the plane where the support portion 222 is located, the structure volume of the terminal structure 200 assembled on the insulating base 100 is smaller, and the terminal structure 200 reliably contacts the electronic components, thereby making the connector assembly 10 smaller.
[0065] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
