'There is a possible problem: when the user uses a vertical upward force to move the card inserted in the slot upwards, if the barbed portion (11〇) can provide insufficient maintenance When the plurality of terminals (10) are fixed to the casing (10), the plurality of terminals (10) are detached from the casing (102). To solve this problem, the related technique is to increase the number of ends: the barb on the barb or the size of the barbs to increase the shell and the multiple ends: ^The maintenance force n increases the number of barbs or It is only augmented; the size of the thorn will reduce the impedance due to the increase of the barbed cross-sectional area. For the signal integration of the connector design, it is necessary to provide 112608.doc • 6 - 200810254 shell and plural A sufficient amount of force between the terminals and a connector suitable for impedance. SUMMARY OF THE INVENTION The present invention relates to a connector comprising: a private body having a slot surrounded by a pair of longitudinal walls and a pair of lateral walls, and: for receiving a card One of the sides; a plurality of terminals maintained between the longitudinal walls. Each of the plurality of terminals has a contact for electrically connecting to the card. Wherein each of the plurality of terminals has a pair of main barbs and at least two pairs of secondary barbs for maintaining the terminal in the housing, and a terminal-to-secondary barb system and adjacent The terminals are arranged in such a way that the secondary barbs are offset from each other. It will be appreciated by those skilled in the art that the present invention is not limited to the embodiments and methods, although the following detailed description will be considered as preferred embodiments and methods. In contrast, the invention has a wide range of applications. [Embodiment] Aspect 3 shows an embodiment of a plurality of terminals (306) in the connector (100) of the present invention. In this embodiment, the plurality of terminals (3〇6) include a contact portion (3〇8) for electrically connecting to one of the cards inserted in the slot, and one for the plurality of terminals (306) The barbed portion (31〇) of the casing (1〇2) and the tail end portion (32〇) for connection with a circuit board are maintained. The barb portion (31〇) of each of the plurality of terminals (3〇6) includes a pair of main barbs (3i〇a, and at least two pairs of secondary barbs (312a, 312b, 314a, 314b), And the main barbs and the secondary barbs are protruded from the terminal in a direction opposite to each other, and the main barbs (3 10a, 3 10b) and the secondary barbs (3 12a, 312b, 112608) .doc 200810254 3 14a, 314b) protrudes from the center of the terminal to the left and right sides. In one embodiment of the invention, as shown in Figure 3, the person of the terminal (e.g., 3〇6a) is barbed ( 312a, 312b, 314a, 3 14b) are arranged to be barbed (313a, 313b, 315a, 3 15b) with adjacent terminals (3〇6b) in such a manner as to be offset from each other. , can increase the distance between the plurality of terminals (3〇6) so as to have appropriate impedance between the terminals. In the consistent embodiment of the present invention, as shown in Figure 3, the main barbs _ (31〇a, 310b) is greater than the secondary barbs (312a, 312b, M4a, 3 14b) whereby the primary barbs (3 i 〇a, 3 〇 b) are used to provide the plurality of terminals (306) ) with shell The main maintaining force between the bodies (102), and the at least two pairs of secondary barbs (312a, 312b, 314a, 314b) are used to further strengthen the connection between the plurality of terminals (306) and the casing (1〇2) If not mentioned, if the number of barbs or the size of the barbs is increased on the terminal, the white will decrease the impedance due to the increase of the barbed cross-sectional area, but if the signal integration is based on the connector design. The reduction of the impedance due to the increase in the cross-sectional area of the ridge must be considered at the same time. In summary, the connector terminal in one embodiment of the present invention can be designed to have a pair of main barbs (31 (^, 3101>) and at least two pairs of minor barbs (312a, 312b, 314a, 314b) relative to the main barb (31 (^, 31〇7). The conventional connector shown in FIG. The terminal comprises two barbs of the same size and the dimensions are the same as the main barbs (310a, 310b) in one embodiment of the invention, as shown in Figures 4a and 4b (due to the lower Figures 4a and 4b). Barbs have the same dimensions, which are not discussed here), the total barbs in conventional connector terminals The area (442) is greater than the total cross-section of the two pairs of secondary barbs in an embodiment of the invention 112608.doc 200810254 (and 4 by this structure, which is only a connection increase of the number of barbs relative to the conventional In terms of terminals, in the present invention, only two pairs of minor barbs (31:^, 3121), 3148, 3141> which are smaller than the main barbs (31 (^'3101>), can be used not only for the piano ( 102) The maintenance force between the terminal and the terminal (3〇6) can avoid the disadvantage of the signal integration of the connector due to the increase of the barbed cross-sectional area on the terminal (3G6) and the low impedance. Those skilled in the art will recognize that many modifications can be made to the invention. Correct
