The connector is provided with a plurality of contact members so as to engage the appropriate contact pads 34a on the larger card. A connector 30 receives a small-sized standard memory card ("smaller card") 40 inserted in the connector in the direction of arrow 42. The connector is then inserted into the receptacle of the memory card connector 32 in the direction of arrow 44. Therefore, either the connector 30 or the larger card 34 conforming to the smaller card 40 can be selectively inserted into the memory card connector. 10 #Refer to Figures 1 to 3, the pin is extremely simple because it includes only three components and a plurality of terminals. In detail, the connector includes a front "electric body element 46, a rear dielectric housing element 48; _metal casing%; a plurality of conductive terminals 52. The dielectric housing element may be molded from a plastic material. Metal The shell can be stamped and formed from a thicker sheet metal material, while the terminals 52 to 15 are stamped and formed from a thinner sheet metal material. The Li shell element 46 of the joint 30 includes a front butt end 46a and a rear joint end 46b. A plurality of slots 46c are formed adjacent to the front mating end on the bottom side of the front case element. A pair of flexible latch arms 54 summarize the rear engaging end 4 6 b of the front case element on the opposite side. Protrude backward. Each flexible latch arm 20 has an inner latch hook 54a and an outer latch hook 54b. The rear body element 48 of the joint 30 includes a front terminal mounting section 4% and a bottom wall 48c opposite A pair of side wall sections 4 extending rearward from the front section on the side. The uranium terminal mounting section 48a defines a front joint end 48d of the rear shell element. The top of the front section 48a is concave like 48e. A pair of latch grooves The grooves are formed in the front corners of the rear housing elements at the opposite ends of the terminal mounting section 48a of the terminal installation 200529500. To receive the flexible latch arm 54 of the front housing element. A latch hole (not visible in the figure) is formed in the inside rear corner of the latch groove to receive the inner latch hook 54a of the latch arm 54. Terminal 52 Protrudes forward from the rear housing element into the front housing element to engage the contact piece 38 of the connector 32. The metal shell 50 of the connector 30 has a U-shaped cross-section to include a top wall 50a and a top wall 50a along the top wall. A pair of side walls 50b running on opposite side edges. A pair of latches L50c are formed in the front end points of the side walls. A mounting lip 50d protrudes forward from the top wall 50 and shifts slightly downward or inward from there. 10 The front housing is made by inserting the flexible latch arm 54 of the front housing element into the interlocking groove 56 of the rear housing element until the inner interlocking groove 54ai is clasped in the flashlock hole of the flashlock groove. The element 46 is assembled into the rear case element 48. When assembled as shown in Figs. 2 and 3, the two case elements are merged to form a shape substantially the same as the shape of the larger card 34 shown in Fig. 4. After the two shell elements are assembled 15, the side wall 50b of the shell is slid over the side wall segment 48b of the rear shell element until the The latch hole 50c in the wall is riveted until the latch hook 54b outside the flexible flash arm 54 of the front housing element is latch-engaged to assemble the metal sheath 50.

The tenth and eleventh display terminal mounting sections of the rear housing element 48 include a plurality of through-holes 70 which are notch-shaped as shown at 70a. The passageway fixes the terminal mounting section 52c, and the chamfered mouth of the passageway facilitates the joint insertion of the terminal into the passageway. The channel is T-shaped to conform to the stamped and formed 15 configuration of the terminal. Figures 12 to 16 show the operation sequence when the joint 30 is assembled. First, while the terminal is still attached to the carrier strip 62, the terminal is jointly inserted into the through-channel 70 of the rear housing element 48 in an arrow 72 of FIG. 12 in the middle. The terminal is inserted until the offset portion 52f (Fig. 5) of the terminal abuts against the front joint 20 end 48d of the rear case member. At this point, referring back to Figs. 7 and 8, it can be seen that the contact portion 52a is narrower than the mounting section 52o and the offset portion 52f. Referring again to the nth figure, it can be seen that each of the through channels 70 is T-shaped and has a narrower upper portion 70b and a wider lower portion 70c. During terminal insertion, the narrower contact portion is inserted into the narrower portion 70b of the channel, and the wider mounting section 52c is inserted into the wider portion 70c 11 200529500. Since the offset portion 52f is also wider, as will be seen in more detail below, the offset portion will abut against the front engaging end 48d of the rear housing on the opposite side of the narrower portion 70b of the channel. After the terminal is fully inserted into the rear housing element 48, as shown in FIG. 14, the carrier strip 62 is broken away from the terminal. This is accomplished by bending the carrier strip back and forth until the carrier strip breaks off the terminal along the dividing line 66 (Figure 6). The front case member 46 is then assembled to the rear case member 48 as described above and as shown in FIG. This effect is achieved by inserting the flexible latch arm 牝 of the front housing element into the latch groove 56 in the rear housing element. 10 The metal shell 50 is then assembled to the rear housing element in the direction of arrow 72 as shown in FIG. 16 and as described above. When fully assembled, the latch hole 50c in the side wall 50b of the case is riveted to the outside of the flexible latch arm 54 of the front housing element 46 and the latch hook 54c is in latch engagement. The downwardly offset mounting lip 50d of the metal shell is moved into the recessed area of the rear body member and then located below the front housing 15 member. Fig. 17 shows that the grooves on the front bottom side of the front case member 46 are guided to the plurality of channels 76 in the front case member to receive the pad portion 52b of the terminal 52. This exposes the crotch portion to engage the contact member 38 (supplier) of the memory card connector 32, while the pad portion 52b is supported by the plastic material of the front case member. Fig. 20 shows that the offset portion 52f of the terminal 52 is biased against the front joint end point of the rear case element. When the casing section 46 is assembled to the rear casing, the rear joint end point 46b of the front casing element is abutted against the rear casing element and is inserted into the casing or clamped in the terminal. Move department. This secures the terminal firmly in the connector. Fig. 18 also shows how the metal housing sleeve 50 is shifted downwards 12 200529500 how the mounting lip 50d moves into a slot inside the rear housing element 46 ". This can hold the top wall 50a of the housing sleeve down in the joint Finally, FIG. 19 shows that the two external terminals of the joint may include a ground terminal. In particular, the two external terminals include an offset mounting lip 50d protruding upward and which can be engaged with the metal shell 50 of the offset mounting lip 50d. This allows the metal case to be shared by the ground terminal, and the ground terminal can engage the appropriate ground contact (Figure 38, Figure 4) of the memory card connector 2. If the memory card connector is mounted on a printed circuit board, Therefore, the metal shell is grounded to the appropriate ground trace on the circuit board via the two external ground terminals of the connector. 10 Solve the invention The invention can be implemented in other specific forms without departing from the spirit and central features of the invention.
