Abstract
Description
Technical Field
[0001] The utility model relates to a connector, in particular to a card edge connector. Background Art
[0002] According to the current card edge connector, when installing the terminals, since each terminal is long, after the terminal groups are assembled, the terminals in each terminal group will have different heights. When the docking connector is inserted, some terminals with higher heights due to the larger bending amplitude will be pressed by the docking connector and deformed or even broken, or some terminals with lower heights due to the smaller bending amplitude cannot effectively contact the docking terminals in the docking connector, thereby causing poor contact, unstable signals or failure to transmit signals.
[0003] Therefore, how to improve the uniformity of the height of each terminal in the card edge connector to improve the plugging stability and avoid damage caused by the plugging of the docking connector is indeed a problem that relevant technical personnel need to think about and solve. Utility Model Content
[0004] The utility model provides a card edge connector, aiming to solve the above technical problems.
[0005] The present invention provides a card edge connector, which includes: an insulating shell, which defines at least one socket, an insertion space connected to the socket, a plurality of first pre-stressing structures on the inner wall surface of one side of the insertion space, and a plurality of second pre-stressing structures on the inner wall surface of the other side of the insertion space and respectively corresponding to each of the first pre-stressing structures; at least one first terminal group, which includes a plurality of first terminals and a first seat for each of the first terminals to be set, wherein each of the first terminals defines a first welding section, a first connecting section extending from the first welding section and a first elastic contact section extending from the first connecting section; and at least one first terminal group. Two terminal groups, which include a plurality of second terminals and a second seat body for each second terminal to be inserted, wherein each second terminal defines a second welding section, a second connecting section extending from the second welding section and a second elastic contact section extending from the second connecting section, wherein the first terminal group is composed of the first seat body combined with the second seat body of the second terminal group and inserted into the socket, each first elastic contact section abuts against the first pre-pressing structure, and each second elastic contact section abuts against the second pre-pressing structure, so that each first elastic contact section and each second elastic contact section are restricted to the same height position.
[0006] Preferably, a first space is defined adjacent to the first pre-pressing structure, and a second space is defined adjacent to the second pre-pressing structure.
[0007] Preferably, the insulating shell defines a docking port for inserting a tool, and the tool causes each of the first elastic contact segments and each of the second elastic contact segments to abut against two sides so as to be inserted into the first space and the second space respectively. When the tool is removed, each of the first elastic contact segments abuts against the first pre-stressing structure, and each of the second elastic contact segments abuts against the second pre-stressing structure.
[0008] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:
[0009] The first elastic contact segment and the second elastic contact segment are respectively guided to the first pre-pressing structure and the second pre-pressing structure to complete the abutment, so that each first elastic contact segment and each second elastic contact segment are restricted to the same height position, thereby avoiding possible poor contact or damage to the terminal due to squeezing when plugging the docking connector due to different heights.

DETAILED DESCRIPTION
[0018] Please refer to Figure 1 and Figure 2 The figure is a three-dimensional schematic diagram of the card edge connector of the utility model and a three-dimensional exploded schematic diagram of the card edge connector. Figure 3 and Figure 6 The utility model is a card edge connector, the card edge connector 1 mainly comprises: an insulating housing 10, a first terminal group 12 and a second terminal group 14, wherein the insulating housing 10 defines a socket 100, a docking port 101, an insertion space 102, a first pre-pressing structure 103 and a second pre-pressing structure 104, wherein the socket 100, the docking port 101 and the insertion space 102 are interconnected, each first pre-pressing structure 103 is located on the inner wall surface of one side of the insertion space 102, and each second pre-pressing structure 104 is located on the inner wall surface of the other side of the insertion space 102 and corresponds to each first pre-pressing structure 103 respectively.
[0019] The first terminal set 12 includes a plurality of first terminals 120 and a first base 122 for mounting each first terminal 120 . Each first terminal 120 is defined by a first welding section 1200 , a first connecting section 1202 extending from the first welding section 1200 , and a first elastic contact section 1204 extending from the first connecting section 1202 .
[0020] The second terminal group 14 includes a plurality of second terminals 140 and a second seat body 142 for inserting each second terminal 140, each second terminal 140 is defined by a second welding section 1400, a second connecting section 1402 extending from the second welding section 1400 and a second elastic contact section 1404 extending from the second connecting section 1402, wherein the first terminal group 12 is composed of a first seat body 122 combined with the second seat body 142 of the second terminal group 14, and is inserted and arranged by the socket 100, each first elastic contact section 1204 abuts against the first pre-pressing structure 103, and each second elastic contact section 1404 abuts against the second pre-pressing structure 104, so that each first elastic contact section 1204 and each second elastic contact section 1404 are restricted to the same height position.
[0021] The insulating housing 10 defines a first space 1030 adjacent to the first pre-pressing structure 103 , and defines a second space 1040 adjacent to the second pre-pressing structure 104 .
[0022] For reference Figure 3 , Figure 4 and Figure 5The figure shows a cross-sectional action structure diagram of the first terminal group and the second terminal group of the utility model after being assembled and inserted into the insulating housing, a cross-sectional action structure diagram of inserting the jig and holding open each first terminal and each second terminal, and a cross-sectional action structure diagram of the jig being pulled out to complete the mutual abutment between the terminals and the pre-pressing structure. As can be seen from the figures, the docking port 101 defined by the insulating housing 10 is used not only for the plug-in connection of the docking connector, but also for inserting the jig 2 from the docking port 101 to the insertion space 102 during the assembly after the first terminal group 12 and the second terminal group 14 are combined. At this time, the jig 2 allows the first elastic contact section 1204 of each first terminal 120 in the first terminal group 12 to be guided to one side of the jig 2, and allows the second elastic contact section 1404 of each second terminal 140 in the second terminal group 14 to be guided to On the other side of the tool 2, the first elastic contact section 1204 and the second elastic contact section 1404 stretched on both sides of the tool 2 will be guided to the first space 1030 and the second space 1040 respectively. After the first terminal group 12 and the second terminal group 14 are inserted to the bottom, the tool 2 can be pulled out. At this time, the first elastic contact section 1204 will be pushed up by the first pre-pressing structure 103 to maintain the same height. Similarly, the second elastic contact section 1404 will also be pushed up by the second pre-pressing structure 104 to maintain the same height.
[0023] Therefore, when the first elastic contact segment 1204 and the second elastic contact segment 1404 are respectively guided to the first pre-pressing structure 103 and the second pre-pressing structure 104 and complete the abutment, the first elastic contact segment 1204 and the second elastic contact segment 1404 are restricted to the same height position, thereby avoiding possible poor contact or damage to the terminal due to squeezing when plugging the connector due to different heights.
