[0038] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0039] like Figures 1 to 4 As shown, an electrical connector 10 of an embodiment includes a terminal 100, a solder ball 200 and an insulating seat 300. The terminal 100 includes a first main elastic arm 110, a clamping elastic arm group 120 and a second main elastic arm 130 which are fixedly connected in sequence. Figures 5 to 7 The clamping spring arm assembly 120 is provided with a clamping groove 121 , and the solder ball 200 is used to be pressed into the clamping groove 121 by interference during assembly, so that the solder ball 200 is cold-implanted and pressed into the clamping groove 121 .

[0040] In one embodiment, the insulating seat 300 is provided with a through cavity 302, and the inner wall of the through cavity 302 is provided with a drawer groove 304 extending to the first side 301 of the insulating seat 300, and the first main elastic arm 110 is inserted into the drawer groove 304. Part of the second main elastic arm 130 is located in the through cavity 302, and the first main elastic arm 110 and the second main elastic arm 130 are both protruding from the first side; the clamping elastic arm group 120 is protruding from the second side 303 of the insulating seat 300, the first side and the second side are arranged opposite to each other, and the second side is respectively provided with a first stop column 303a and a second stop column 303b, the first stop column 303a and the second stop column 303b are arranged opposite to each other on both sides of the solder ball 200, and the first stop column 303a and the second stop column 303b are both staggered from the clamping elastic arm group 120.

[0041] When assembling the electrical connector 10, the terminal 100 is first placed in the through cavity 302, so that the first main elastic arm 110 is inserted into the drawer groove 304, and part of the second main elastic arm 130 is located in the through cavity 302, and the first main elastic arm 110 and the second main elastic arm 130 are both protruding from the first side, and the clamping elastic arm group 120 protrudes from the second side of the insulating seat 300; then the solder ball 200 is pressed into the clamping groove 121 with interference fit, so as to realize the freedom constraint of the solder ball 200 on the second side away from the first side. Since the first stop column 303a and the second stop column 303b are respectively protruding from the second side, the first stop column 303a and the second stop column 303b are relatively arranged on both sides of the solder ball 200, and the first stop column 30 3a and the second stop column 303b are staggered with respect to the clamping spring arm group 120, so that the freedom of the solder ball 200 in four different directions within the plane where the second side is located is constrained, so that the solder ball 200 can be reliably assembled and fixed on the insulating seat 300; then the solder ball is soldered to the circuit board; in the above-mentioned electrical connector 10, the clamping spring arm group 120 protrudes from the second side of the insulating seat 300, and the solder ball 200 can be assembled in the clamping groove 121 of the clamping spring arm group 120 of the terminal 100 to achieve assembly. Compared with the prior art, the above-mentioned electrical connector 10 has lower requirements on the processing accuracy of the insulating seat 300, which makes the assembly difficulty of the electrical connector 10 lower, and at the same time facilitates the rapid assembly of the terminal 100 and the solder ball 200.

[0042] See also Figure 4 and Figure 6 Furthermore, the clamping elastic arm group 120 includes two relatively arranged clamping arms 122, and the first blocking column 303a and the second blocking column 303b are staggered from the connecting line of the two clamping arms 122, so that the first blocking column 303a and the second blocking column 303b are staggered from the clamping elastic arm group 120.

[0043] See also Figure 4 and Figure 5 In one embodiment, the number of the terminals 100 and the through cavities 302 are both multiple, and the multiple through cavities 302 are arranged in multiple rows. The first main elastic arm 110 of each terminal 100 is inserted into the drawer groove 304 of the corresponding through cavity 302.

[0044] See also Figure 4 and Figure 5 In one embodiment, the insulating seat 300 includes a frame 310, a plurality of horizontal partitions 320 and a plurality of vertical partitions 330. The frame 310 forms a partition cavity 312. The plurality of horizontal partitions 320 are arranged side by side in the partition cavity 312 to divide the partition cavity 312 into m partition areas 314. Each partition area 314 is provided with n vertical partitions 330. The adjacent two vertical partitions 330 of two adjacent partition areas are staggered, so that the adjacent two terminals 100 of two adjacent rows are staggered, so that the structure of the electrical connector 10 is more compact and the volume of the electrical connector 10 is smaller. Wherein, m and n are both positive integers. In this embodiment, a through cavity 302 is formed between the adjacent two vertical partitions 330 of each partition area 314-312. In one embodiment, the width of each horizontal partition 320 is equal to the width of any vertical partition 330, so that the insulating seat 300 is better formed. In this embodiment, the frame 310 , the plurality of horizontal barriers 320 , and the plurality of vertical barriers 330 are an integral injection-molded structure.

[0045] In other embodiments, the width of each horizontal partition 320 is not limited to be equal to the width of any vertical partition 330. For example, in one embodiment, the width of each horizontal partition 320 is greater than the width of any vertical partition 330, and the difference between the width of each horizontal partition 320 and the width of any vertical partition 330 is equal to (5% to 10%) of the width of the vertical partition 330, so as to prevent the insulating seat 300 from warping during the molding process.

[0046] See also Figure 2 , Figure 3 and Figure 6 In one embodiment, the width of the drawer slot 304 adjacent to the first side is greater than the width of the drawer slot 304 away from the first side, so that the width of the drawer slot 304 narrows from the first side to the second side. Anti-detachment slots 112 are provided on both sides of the first main elastic arm 110. The anti-detachment slots 112 are located at the portion of the drawer slot 304 connected to the second side to prevent the first main elastic arm 110 from detaching from the insulating seat 300 from the drawer slot 304, so that the first main elastic arm 110 is reliably held and installed in the drawer slot 304.

[0047] See also Figure 3 and Figure 6 In one embodiment, two mutually close narrowing protrusions 1212 are provided at the positions corresponding to the retaining groove 121 and the anti-dropping retaining groove 112; the distance between the two narrowing protrusions 1212 of the retaining groove 121 is the smallest, so that the clamping spring arm group 120 can be better elastically compressed to the solder ball 200 after the solder ball 200 is cold-implanted and pressed into the retaining groove 121.

[0048] See also Figure 3 and Figure 5 In one embodiment, a vertical stopper 3022 is protruded from the inner wall of the through cavity 302, and the vertical stopper 3022 is arranged in the drawer groove 304. The vertical stopper 3022 extends to the surface of the second side, so that the vertical stopper 3022 constrains the freedom of the solder ball 200 from the second side toward the first side, so that the solder ball 200 can be more reliably assembled and fixed on the insulating seat 300.

[0049] See also Figures 3 to 6 In one embodiment, the first main elastic arm 110 includes a clamping portion 112, a bent floating portion 114 and a resisting portion 116 which are connected in sequence. The end of the clamping portion 112 connected to the bent floating portion 114 is the root of the terminal 100. The plane where the root of the terminal 100 is located coincides with the plane where the first side is located, so that the structure of the electrical connector 10 is more compact. In other embodiments, the plane where the root of the terminal 100 is located is not limited to coincide with the plane where the first side is located. For example, the plane where the root of the terminal 100 is located is higher or lower than the plane where the first side is located. In this embodiment, the resisting portion is pressed and abuts against the chip of the CPU substrate when the electrical connector is assembled between the circuit board and the CPU substrate, so that the CPU substrate is electrically connected to the circuit board through the electrical connector.

[0050] like Figure 1 and Figure 5 As shown, in one embodiment, the first side 301 is provided with a first support platform 3012 at a position adjacent to the through cavity 302, the first support platform 3012 is provided with a first support plane, the first support plane is higher than the plane of the first side, and the first support platform 3012 is staggered from the terminal 100 to prevent the first main elastic arm 110 and the second main elastic arm 130 from being over-pressed in the vertical direction when in use, thereby ensuring the working stability of the terminal 100 and improving the reliability of the electrical connector 10. In this embodiment, when the abutting portion is pressed and abuts against the chip on the CPU substrate, the abutting portion moves downward until the CPU substrate abuts against the first support platform 3012, at which time the first main elastic arm 110 abuts against the second main elastic arm 130, thereby preventing the first main elastic arm 110 and the second main elastic arm 130 from being over-pressed in the vertical direction when in use.

[0051] In one embodiment, the first side 301 is further provided with a second support platform (not shown) at a position adjacent to the through cavity 302, and the second support platform is provided with a second support plane. The first support plane and the second support plane are located in the same plane. The first support platform 3012 and the second support platform are staggered with respect to the terminal 100. The first support platform 3012 and the second support platform are respectively arranged along the diagonal lines of the terminal 100, thereby further improving the reliability of the electrical connector 10.

The degree of freedom of the lateral direction is constrained. Since the second side is respectively provided with a first blocking column 303a and a second blocking column 303b, the first blocking column 303a and the second blocking column 303b are arranged on both sides of the solder ball 200 opposite to each other, and the first blocking column 303a and the second blocking column 303b are staggered from the clamping elastic arm group 120, so that the degrees of freedom of the solder ball 200 in four different directions within the plane where the second side is located are constrained, so that the solder ball 200 is reliably assembled and fixed on the insulating seat 300;

[0054] 2. In the above-mentioned electrical connector 10, the clamping spring arm group 120 protrudes from the second side of the insulating seat 300, and the solder ball 200 can be assembled in the clamping groove 121 of the clamping spring arm group 120 of the terminal 100 to achieve assembly. Compared with the prior art, the above-mentioned electrical connector 10 has lower requirements on the processing accuracy of the insulating seat 300, which makes the assembly difficulty of the electrical connector 10 lower, and at the same time facilitates the rapid assembly of the terminal 100 and the solder ball 200.

[0055] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
