For example, in computers or communication equipment, according to different needs of users, it is necessary to connect expansion modules (such as display cards, network cards, etc.) or sub-circuit boards with different functions to the motherboard to expand the functionality of electronic devices. Sometimes, multiple electrical connectors need to be provided on the motherboard to receive expansion modules of different specifications. To reduce installation space, one electrical connector can be used to receive multiple expansion modules. However, different expansion modules may have different information transmission paths and working voltages, so if a wrong expansion module is inserted, it may cause damage or malfunction of the expansion module.

The two rows of storage slots on both sides of the slot 105 include a row of first storage slots 101 and a row of second storage slots 102, and the partition includes a first partition between two adjacent first storage slots 101 103 and a second partition 104 located between two adjacent second receiving grooves 102 , each first combining arm 2 is configured to be able to be inserted into a corresponding first receiving groove 101 . In this way, during the process of installing the identification key 10 to the insulating body 100 , each first combining arm 2 is inserted into a corresponding receiving groove in the first direction under the guidance of the first partition. When the identification key 10 is inserted into the insulating body 100 , the positioning part 3 can snap fit with the partition part, so that the identification key 10 can be detachably positioned in the insulating body 100 .

Generally, each first partition 103 has a predetermined extension length in the first direction, and the end 1031 of the first partition 103 is located inside the insulating body 100 . In one embodiment, the positioning part 3 is further configured such that when the identification key 10 is inserted into the insulating body 100 , the positioning part 3 can protrude beyond the end 1031 of the first partition 103 inside the electrical connector. In detail, the identification key 10 includes two first combining arms 2 extending from the main body 1 that are substantially parallel to each other, a first partition 103 is accommodated between the two first combining arms 2, and two positioning parts 3 (Fig. 4 only shows one) formed on the outer sides of the two first coupling arms respectively, so that when the identification key 10 is inserted into the insulating body 100, the two positioning parts 3 can be respectively coupled between the two first coupling arms 2 The first partition adjacent to the other first partition is located outside the end 1031 inside the insulating body 100 .

When reaching the final joint position, the positioning part 3 moves outward in the second direction from the ends 1031 of the two outer first partitions 103 inside the insulating body 100, and at the same time, the two outer first partitions 103 are lost due to The extrusion of the positioning part 3 returns to the original state. In this way, the positioning part 3 snap fits with the end 103 and is blocked by the end 1031 , so that the identification key 10 is relatively firmly held in the insulating housing 100 . A plurality of slope structures 33 - 35 can be formed on the positioning portion 3 to guide the positioning portion 3 into the first receiving groove 101 between the first partitions 103 , and the positioning portion 3 is combined with the end 1031 or released from the end 1031 .

Although the embodiment in which the positioning portion 3 is formed outside the first coupling arm 2 has been described above, the present invention is not limited thereto. One or two positioning parts can also be formed on the inner side of the first combining arm 2, like this, when the identification key 10 is inserted into the insulating body 100, the positioning part and the first partition 103 between the two combining arms 2 end binding.

The second receiving groove 102 is formed on the other inner wall of the slot 105 and is opposite to the first receiving groove 101, and the third receiving groove 102 and the first receiving groove 101 are perpendicular to the first direction and the second direction. The spacing in the direction (thickness direction of the insulating body 100) allows insertion of expansion modules. When the identification key 20 is inserted into the insulating body 100, the two second combining arms 4 are inserted into the corresponding second receiving grooves 102 in the first direction under the guidance of the second partition 104 between the two second receiving grooves 102. slot 102.

Referring to FIG. 3 , there is a distance between the first receiving groove 101 and the second receiving groove 102 in the first direction (width direction), and the first receiving groove 101 is exposed outside the insulating body 100 . Correspondingly, referring to FIGS. 4 and 5, the first coupling arm 2 protrudes from the first surface (lower surface in FIGS. 4 and 5) of the main body 1 facing the first receiving groove 101 and extends in the first direction. Two coupling arms 4 extend in a first direction from a second surface of the main body 1 perpendicular to the first surface. In addition, a channel 21 penetrating in the first direction is defined between the two first coupling arms 2 . In this way, when the identification key 10 is installed on the insulating body 100, as shown in FIG. Under the guidance of 103, the identification key 10 is pushed into the slot 105.

In one embodiment, as shown in FIG. 5 , the first combining arm 2 and the second combining arm 4 are integrally formed through a connecting portion 5 therebetween, which can improve the stability of the entire identification key 10 . Generally, the first receiving groove 101 and the second receiving groove 102 are not aligned in the third direction. Accordingly, the first coupling arm 2 and the second coupling arm 4 are also not aligned in the third direction (the up-and-down direction in FIGS. 4 and 5 ), and a reinforcing portion 6 is formed outside one second coupling arm 4 . When the identification key 10 is installed in the insulating body 100 , the end 61 of the reinforcing part 6 just abuts against the end of the exposed slot 105 of a second partition 104 . Further, a flange 11 is formed on the main body, and the flange is configured to abut against the outer edge of the casing 1 of the insulating body 100 to block the further insertion of the identification key 10 into the insulating body 100 .

According to the electrical connectors of the above-mentioned various embodiments of the present invention, the identification key 10 is detachably inserted into the insulating body 100 in a snap-fit manner, and once installed in place, the identification key 10 is reliably held in the insulating body 100 . According to the length of the expansion module to be inserted, the identification key 10 can be installed on the insulation body 100 by selecting a corresponding position on the insulation body 100, thereby forming an installation space just suitable for the expansion module to be inserted. This reduces the possibility of wrongly inserting the expansion module into the insulating housing 100 . One, two or more than two expansion modules can be installed on the insulating housing 100 according to the number of expansion modules to be inserted. In addition, before installing the identification key 10 to the electrical connector, it is only necessary to remove the conductive terminal at the installation position without changing other structures of the insulating body 100 .
