The channel is fixed to the terminal mounting section 52e' and the chamfered mouth of the channel facilitates the terminal insertion into the channel. The channel is the terminal line _ and the formed figures 12 to 16 show the sequence of operations when assembling the joint 3 。. First, while the terminal is still attached to the carrier strip 62, the terminal 52 is jointly inserted into the through passage 7' of the rear housing member 48 in the direction of the arrow in Fig. 12. The terminal is inserted until the offset portion 52f (Fig. 5) of the terminal abuts against the front end 2' end 48d of the rear housing member. At this point, referring back to Figures 7 and 8, it can be seen that the contact portion 52a is narrower than the mounting portion 52 (and the offset portion 52f. Referring again to Figure u, it can be seen that each of the through passages 70 is T-shaped. With a narrower upper portion 7 and a lower portion 7Ge° during the terminal insertion, the narrower contact portion appears to be inserted into the narrower portion 70b of the passageway, while the wider mounting portion 52c is inserted into the wider portion 7〇c 1249878 Since the offset portion 52f is also wider, as will be seen in more detail below, the offset portion will abut the front engagement end point 48d of the rear housing on the opposite side of the narrower portion 70b of the channel. After the rear housing member 48 is fully inserted, as shown in Fig. 14, the carrier strip 62 is broken away from the terminal. The carrier strip is bent back and forth until the carrier strip is broken along the dividing line 66 (Fig. 6) away from the terminal. This effect is achieved. The front housing element 46 is then assembled to the rear housing element 48 as described above and as shown in Fig. 15. By inserting the flexible latch arm of the front housing element into the latch in the rear housing element This effect is achieved by the groove 56. 10 The metal casing 5〇 is then shown in Figure 16 and as indicated above at arrow 72 Assembly to the rear housing member inwardly. When fully assembled, the flash lock hole 5〇c in the side wall 50b of the housing is riveted to the latching hook 54c other than the flexible latch arm 54 of the front housing member 46. In the latching engagement, the downwardly offset mounting lip 5〇d of the metal casing moves into the recessed area 48e of the rear housing element and is then located below the front housing 15 element. Figure 17 shows the front housing The groove 46c on the front bottom side of the member 46 is guided to a plurality of passages 76 in the m housing member to receive the pad portion 52b of the terminal 52. This exposes the pad portion to engage the contact member 38 of the memory card connector 32 (Fig. 4) At the same time, the pad portion 52b is supported by the plastic material of the front housing member. 20 Figure 18 shows the offset portion 52f of the terminal 52 abutting against the jaw engagement end 48d of the rear housing member 48. When the housing member 46 is assembled In the case of the rear housing element, the rear engagement end 461) of the front housing τ a member abuts against the rear housing element and clamps or clamps the offset of the terminal between the housing elements. This secures the terminal in the connector. Figure 18 also shows how the 12 1249878 mounting lip 50d, which is offset downwardly of the metal casing 5, moves into a groove in the interior of the rear casing member 46. This holds the top wall 50a of the casing downwardly at the joint. Finally, Fig. 19 shows that the outer two terminals of the connector may include a grounding terminal. In detail, the outer two terminals comprise resilient contact ribs projecting upwardly and engaging the offset mounting lip 5 of the metal casing 5〇. 〇d. This allows the metal case to be shared by the ground terminal, and the ground terminal can engage the appropriate ground contact of the memory card connector (38, Figure 4). If the memory card connector is mounted on a printed circuit board Thus, the metal casing is grounded to the appropriate ground traces on the circuit board via the outer two ground terminals of the connector. 10 15 20 It will be appreciated that the invention may be embodied in other specific forms without departing from the spirit and scope of the invention.
