as shown in fig. 1 to 3, the connector assembly 10 of an embodiment includes an insulating base 100 and a terminal structure 200, wherein the terminal structure 200 is mounted on the insulating base 100. Referring to fig. 4 and 5, in one embodiment, the terminal structure 200 includes a terminal fixing portion 210, an elastic bending arm 220, and a terminal abutting portion 230, which are sequentially connected, wherein the terminal fixing portion 210 is fixedly connected to the insulating base 100. The elastic bending moment arm 220 includes a supporting portion 222 and a bending portion 224 connected to each other, wherein an end of the supporting portion 222 away from the bending portion 224 is connected to the terminal fixing portion 210, so that two ends of the supporting portion 222 are respectively connected to the bending portion 224 and the terminal fixing portion 210. The end of the bent portion 224 away from the supporting portion 222 is connected to the terminal abutting portion 230, so that two ends of the bent portion 224 are respectively connected to the supporting portion 222 and the terminal abutting portion 230, and thus the terminal abutting portion 230, the bent portion 224, the supporting portion 222 and the terminal fixing portion 210 are sequentially connected, and the terminal abutting portion 230 and the terminal fixing portion 210 are reliably electrically connected.

As shown in fig. 5, in one embodiment, the supporting portion 222 is used for abutting against the insulating base 100, so that the insulating base 100 is supported by the elastic bending moment arm 220, and thus the elastic bending moment arm 220 is pressed more stably, and the whole terminal structure 200 is pressed more stably. The lowest edge of the contour line of the bending portion 224 and the terminal abutting portion 230 are respectively located at two sides of the plane where the supporting portion 222 is located, that is, the bending portion 224 is located at one side of the plane where the supporting portion 222 is located, and the terminal abutting portion 230 is located at the other side of the plane where the supporting portion 222 is located. Referring to fig. 1, in the present embodiment, the terminal fixing portion 210 abuts against the first electronic component 20, and the terminal abutting portion 230 abuts against the second electronic component 30, so that the first electronic component is electrically connected to the second electronic component through the connector assembly 10.

In the terminal structure 200 and the connector assembly 10, since the supporting portion 222 and the bending portion 224 are connected, the end of the supporting portion 222 away from the bending portion 224 is connected to the terminal fixing portion 210, so that the terminal fixing portion 210 is connected to the elastic bending force arm 220, and since the end of the bending portion 224 away from the supporting portion 222 is connected to the terminal abutting portion 230, so that the terminal abutting portion 230 is connected to the elastic bending force arm 220, so that the elastic bending force arm 220 is connected to the terminal fixing portion 210 and the terminal abutting portion 230, and the insulating base 100 is supported by the elastic bending force arm 220, so that the terminal structure 200 is pressed more stably, and the terminal structure 200 is reliably mounted on the insulating base 100; because the lowest edge of the contour line of the bending portion 224 and the terminal abutting portion 230 are respectively located at two sides of the plane where the supporting portion 222 is located, and the terminal abutting portion 230 is located at the other side of the plane where the supporting portion 222 is located, the structure volume of the terminal structure 200 assembled on the insulating base 100 is small, and the terminal structure 200 reliably abuts against the electronic component, through this design, the low design of the connector assembly 10 can be better realized, and further the volume of the connector assembly 10 is small; the bending portion 224 has better vibration damping performance, so that the terminal structure 200 is better assembled to the insulating base 100.

In the present embodiment, the curvature of each position of the bent portion 224 is equal, that is, the bent portion has an arc-shaped structure with equal curvature, so that the bent portion has better vibration damping performance. It is understood that in other embodiments, the bending portion is not limited to a circular arc structure with equal curvature, for example, the bending portion may also be an arc structure with unequal curvature. Further, the portion where the maximum curvature of the bending portion is located and the terminal abutting portion 230 are respectively located on two sides of the plane where the supporting portion 222 is located, that is, the portion where the maximum curvature of the bending portion 224 is located on one side of the plane where the supporting portion 222 is located, and the terminal abutting portion 230 is located on the other side of the plane where the supporting portion 222 is located. Because the maximum curvature of the bending portion 224 and the terminal abutting portion 230 are located on two sides of the plane of the supporting portion 222, respectively, the bending portion 224 is located on one side of the plane of the supporting portion 222, and the terminal abutting portion 230 is located on the other side of the plane of the supporting portion 222, so that the structure volume of the terminal structure 200 assembled on the insulating base 100 is small, and the terminal structure 200 abuts against the electronic component reliably, thereby achieving the low design of the connector assembly 10, and further making the size of the connector assembly 10 small.

In one embodiment, the first electronic component may be a printed circuit board and the second electronic component may be a printed circuit board or a CPU. Alternatively, the first electronic component may be a printed circuit board or CPU and the second electronic component may be a printed circuit board. In one embodiment, the first electronic component and the second electronic component are printed circuit boards, the first electronic component has a first conductive sheet, and the terminal fixing portion 210 abuts against the first conductive sheet, so that the terminal structure 200 is electrically connected to the first electronic component. The second electronic component has a second conductive sheet, and the terminal abutting portion 230 abuts against the second conductive sheet, so that the terminal structure 200 is electrically connected to the second electronic component.

In one embodiment, the first electronic component and the second electronic component are disposed in parallel with the insulating base 100, so that the first electronic component is better electrically connected with the second electronic component through the connector assembly 10. And/or, in one embodiment, the terminal interference portion 230 is bent, such that the terminal interference portion 230 elastically interferes with the second electronic component, and the terminal interference portion 230 better interferes with the second electronic component.

As shown in fig. 5, in one embodiment, the lowest edge of the contour line of the bending portion is located below the supporting portion, so that the deformation at the center of the bending portion 224 is located below the supporting portion 222, which reduces the space occupied by the elastic bending moment arm 220, and further reduces the volume of the terminal structure 200 assembled on the insulating base 100.

In order to fix and connect the terminal fixing portion 210 to the insulating base 100 quickly and reliably, as shown in fig. 5, in one embodiment, the insulating base 100 is formed with a clamping groove 102, and the terminal fixing portion 210 is inserted into the clamping groove 102 and clamped with the insulating base 100, so that the terminal fixing portion 210 is fixed and connected to the insulating base 100 quickly and reliably.

As shown in fig. 5 and fig. 6, further, the insulation base 100 is formed with a supporting protrusion 104, the extending direction of the supporting force of the supporting protrusion 104 to the supporting portion 222 passes through the contact point of the terminal contact portion 230, wherein the contact point contacts the second electronic component, because the extending direction of the supporting force of the supporting protrusion 104 to the supporting portion 222 passes through the contact point of the terminal contact portion 230, the extending direction of the supporting force of the supporting protrusion 104 to the supporting portion 222 passes through the contact point of the terminal contact portion 230 and the contact point of the second electronic component, when the contact point of the terminal contact portion 230 is pressed, the contact point of the supporting portion 222 and the terminal contact portion 230 forms a self-stabilized force system, so as to reduce the force between the conductive contact portion 240 and the terminal fixing portion 210, thereby avoiding the problem that the welding interface of the conductive contact portion 240 and the terminal fixing portion 210 is damaged easily, and improving the service life of the connector assembly 10, meanwhile, the problem that the joint of the terminal structure 200 and the insulating base 100 shakes due to large stress is avoided, and the reliability of the electrical connection between the terminal structure 200 and the electronic element is improved.

As shown in fig. 5 and fig. 6, in one embodiment, the insulation base 100 further has a receiving groove 106 communicated with the clamping groove 102, and the supporting protrusion 104 is formed on an inner wall of the receiving groove 106, so that the insulation base 100 can better abut against and be supported by the supporting portion 222. The elastic bending arm is accommodated in the accommodating groove 106, and the lowest end of the bending portion 224 of the elastic bending arm is lower than the supporting portion 222, so that the insulating base 100 can better accommodate the terminal structure 200, and the lowest end of the bending portion 224 of the elastic bending arm is lower than the supporting portion 222, so that the product space can be maximally utilized, the structure of the connector assembly 10 is more compact, the low height of the connector assembly 10 is realized, and the conductive terminal is ensured to have excellent mechanical properties. In this embodiment, the elastic bending arm is bent to make the elastic bending arm absorb vibration better, so that the terminal structure 200 has better vibration damping performance and the connector assembly 10 is easy to be designed to be low. In one embodiment, the connector assembly 10 is an LGA connector.

As shown in fig. 5 and 6, further, the receiving groove 106 includes a deformation limiting groove 1062 and a receiving groove 1064, the deformation limiting groove 1062 is communicated with the engaging groove 102 through the receiving groove 1064, that is, the receiving groove 1064 is respectively communicated with the deformation limiting groove 1062 and the engaging groove 102, and the supporting protrusion 104 is formed between an inner wall of the deformation limiting groove 1062 and an inner wall of the engaging groove 102, so that the insulating base 100 is better abutted against and supported by the supporting portion 222. In this embodiment, the bending portion 224 is located in the deformation limiting groove 1062, so that the bending portion 224 abuts against the inner wall of the deformation limiting groove 1062 when being deformed by pressure, and thus both the deformation limiting groove 1062 and the supporting surface can abut against and support the terminal structure 200, so that the terminal structure 200 is assembled and connected to the insulating base 100 more stably, and meanwhile, the deformation limiting groove 1062 limits the deformation of the terminal structure 200 caused by pressure, thereby avoiding the problem that the terminal structure 200 is easily damaged due to excessive deformation caused by pressure. Further, the terminal interference portion 230 protrudes from the insulating base 100, so that the terminal interference portion 230 can better interfere with the second electronic component, and the connector assembly 10 can be electrically connected to the second electronic component. Because the supporting protrusion 104 supports the supporting portion 222, in addition, the bending portion 224 is located in the deformation limiting groove 1062, when the bending portion 224 deforms greatly, the bending portion 224 abuts against 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 fixing portion 210 is connected with the insulating base 100, so that the terminal structure 200 is relatively stable when being pressed, the problem of poor reliability of the electrical connection of the connector assembly 10 is solved, the limiting effect of the deformation limiting groove 1062 is realized, the terminal is prevented from being excessively compressed, and the problem that the terminal is easily subjected to plastic deformation, namely, crush is solved.

As shown in fig. 5, the supporting protrusion 104 is further provided with a supporting surface 1041, and the supporting surface is a planar structure, so that the supporting surface is better supported on the supporting portion 222, and the structure of the supporting surface is simpler. It is understood that in other embodiments, the support surface is not limited to a planar structure, but may also be a curved structure or other shapes.

As shown in fig. 5 and fig. 6, in one embodiment, the surface of the insulating base 100 with the receiving groove 1064 is parallel to the supporting surface, and the supporting surface is supported by the supporting portion 222, and the surface of the insulating base 100 with the receiving groove 1064 is parallel to the supporting surface, so that the terminal structure 200 is assembled on the insulating base 100 and can be reliably abutted and electrically connected to the second electronic component. In this embodiment, the second electronic component is a printed circuit board, and the second electronic component is disposed in parallel with the insulating base 100, that is, the second electronic component is disposed in parallel with the surface of the insulating base 100 having the receiving groove 1064, and since the surface of the insulating base 100 having the receiving groove 1064 is disposed in parallel with the supporting surface, the terminal structure 200 can be reliably abutted and electrically connected to the second electronic component.

As shown in fig. 5 and 6, in one embodiment, the terminal structure 200 further includes a conductive contact portion 240, the conductive contact portion 240 is located on one side of the insulating base 100 and welded to the terminal fixing portion 210, and the elastic bending arm is located on the other side of the insulating base 100, so that the conductive contact portion 240 is reliably and fixedly connected to the terminal fixing portion 210, and the terminal structure 200 is reliably and fixedly connected to the insulating base 100. In the present embodiment, the conductive contact portion 240 is located at one side of the insulating base 100 and abuts against the first electronic component, so that the terminal fixing portion 210 is electrically connected to the first electronic component through the conductive contact portion 240.

As shown in fig. 5 and fig. 6, in one embodiment, the terminal fixing portion 210 is formed with a clamping protrusion 212, and the clamping protrusion abuts against the clamping groove 102, so that the terminal fixing portion 210 is clamped in the clamping groove 102 in a limited manner, and the terminal fixing portion 210 is prevented from being separated from a side of the insulating base 100 away from the second electronic component, so that the terminal fixing portion 210 is reliably fixed to the insulating base 100. In one embodiment, the clamping protrusion is an arc protrusion structure, so that the clamping protrusion is better clamped and limited in the clamping groove 102. In one embodiment, the number of the clamping protrusions is two, and the two clamping protrusions are oppositely disposed on two sides of the terminal fixing portion 210, so that the terminal fixing portion 210 is better clamped and limited in the clamping groove 102.

As shown in fig. 6 and 7, the terminal fixing portion 210 further has a holding fastening point 214 formed thereon, the holding fastening point is located outside the fastening groove 102, and the terminal fixing portion 210 is soldered to the conductive contact portion 240 at the holding fastening point. Since the holding fastening point is located outside the fastening groove 102, that is, the highest point of the holding fastening 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 is prevented from being separated from the side of the insulating base 100 away from the first electronic component, and the internal compression stress generated by continuously compressing the insulating base 100 is avoided, so that the internal stress of the whole connector assembly 10 is reduced, and the warpage of the connector assembly 10 is reduced. In one embodiment, the number of the holding fastening points 214 is two, and the two holding fastening points are disposed on two sides of the terminal fixing portion 210, so as to better prevent the terminal fixing portion 210 from being separated from the fastening groove 102.

As shown in fig. 6 and 7, in one embodiment, the terminal interference portion 230 is located above the supporting portion 222, so that the terminal structure 200 forms a self-stable stress system when the terminal interference portion 230 is pressed against the second electronic component, thereby reducing the stress on the connection between the terminal fixing portion 210 and the insulating base 100. In one embodiment, the supporting force of the supporting portion 222 exerted by the supporting protrusion 104 extends through the abutting point of the terminal abutting portion 230, so that the supporting protrusion 104 is better abutted and supported on the terminal structure 200. In this embodiment, the terminal abutting portion 230 is located right above the supporting portion 222, when the abutting point of the terminal abutting portion 230 is pressed, the abutting point of the supporting portion 222 and the terminal abutting portion 230 forms a self-stable stress system, so as to better reduce the stress between the conductive contact portion 240 and the terminal fixing portion 210, thereby better avoiding the problem that the welding interface between the conductive contact portion 240 and the terminal fixing portion 210 is damaged and easily damaged, prolonging the service life of the connector assembly 10, avoiding the problem that the joint between the terminal structure 200 and the insulating base 100 is shaken due to a large stress, and improving the reliability of the electrical connection between the terminal structure 200 and the electronic component.
