Here, the bottom wall portion 11b includes: a terminal holding recess 11c for holding the terminal 51; and a solder tail opening 11d. Terminal holding recess 11c and solder tail The portion opening 11d is an opening that penetrates the bottom wall portion 11b in the thickness direction. There is a single welded tail opening 11d, and all of the tail portions 51d (which are the welded portions of the terminals 51) are exposed to the solder tail opening 11d. The tail portion 51d is soldered to a connection pad (not shown) that is coupled to the conductive traces on the substrate to establish a reliable electrical connection. The plurality of terminal holding recesses 11c are formed in a row extending in the front-rear direction of the susceptor 11. In the example shown in the drawing, there are two rows of three terminal holding recesses 11c per row. In other words, the plurality of terminal holding recesses 11c and the terminals 51 in the respective terminal holding recesses 11c are arranged in two rows and each row extends in the front-rear direction of the susceptor 11.

Referring to FIGS. 4A to 4D, at least a part of the base portion 51a of each terminal 51 is embedded in the bottom wall portion 11b, the tail portion 51d is exposed in the solder tail opening 11d, and the remaining portion is exposed in the terminal holding recess portion 11c. In each terminal 51, the base end of the arm portion 51b is connected to the base portion 51a. The arm portion 51b itself is elastically deformable, has a constant thickness, and functions as a cantilever beam. When the initial state in which the external force is not applied, the arm portion 51b has the shape shown in Figs. 4C and 4D. More specifically, as shown in FIG. 4C, the arm portion 51b has a flat plate portion 51b1 formed in the same plane as the base portion 51a and extending parallel to the upper surface of the bottom wall portion 11b; a curved portion 51b2, connected a front end of the flat plate portion 51b1 and shaped to have a curved surface having a center of curvature in a side view; and a front portion 51b3 connected to the front end of the curved portion 51b2 and above the upper surface of the bottom wall portion 11b . The front portion 51b3 may have a straight line shape or may have the same portion as the curved shape of the curved portion 51b2. In the initial state, the arm The portion 51b has a shape in a side view that does not include a deflection point but is linearly connected to the base portion 51a.

As shown in FIG. 4A, when viewed from above, the arm portion 51b has a pentagon shape similar to the home plate in the baseball, and the top portion 51c at the apex faces the left and right side wall portions 11e. Each of the terminals 51 is disposed laterally with respect to the insertion direction of the card 101 or the card tray 161, and each arm portion 51b extends from the base portion 51a in the lateral direction of the base 11. The second oblique portion 51e is formed on both sides of the top portion 51c at the position of the front end (free end) of each arm portion 51b. The oblique portion 51e is symmetrically inclined with respect to the center line of the arm portion 51b passing through the top portion 51c. The oblique portion 51e exists at least in the entire range of the front portion 51b3, and there is no need to have a portion extending to the curved portion 51b2. In plan view, the top portion 51c preferably becomes a point. However, the top portion 51c preferably has a rounded point.

One opening 51f is formed in the center of the arm portion 51b and penetrates the arm portion 51b in the thickness direction. In the plan view, the opening portion 51f has a rhombic shape extending from the vicinity of the front end of the arm portion 51b to the vicinity of the base portion, and the long axis of the rhombus extends in the extending direction of the arm portion 51b. More specifically, the opening portion 51f has a symmetrical shape with respect to the center line of the arm portion 51b, and the width dimension (the dimension orthogonal to the center line direction) of the portion of the arm portion 51b other than the opening portion 51f is from the arm portion 51b. The front end gradually increases linearly toward the base end. The arm portion 51b (having a constant thickness and serving as a cantilever beam) has an isosceles triangle shape in plan view. In other words, the arm portion 51b approximately has a beam of equal strength in which the bending stress is uniform in the longitudinal direction along the center line.

The top portion 51c serves as a contact portion of the terminal 51 and is upwardly biased by the elastic action of the arm portion 51b to contact the corresponding electrode pad on the card 101 inserted in the card tray 161 in the card connector 1. The number and layout of the terminals 51 can be varied to accommodate the number and layout of the electrode pads on the card 101.

The holding elastic member 25 is provided in each of the side wall portions 11e to hold and fix the card tray 161. Each of the holding elastic members 25 is an elongated plate-shaped elastic member that extends in the front-rear direction, and the holding convex portion 25a is formed in the vicinity of the center of each of the holding elastic members 25 and protrudes inward in the lateral direction of the susceptor 11. Each of the holding convex portions 25a engages the holding concave portion 168 of the card tray 161, and this holds and fixes the card tray 161 inserted into the card connector 1.

A push rod 22 is slidably attached to the inner side of one of the two side wall portions 11e in the front-rear direction. The push rod 22 is a tray discharge operation element as a tray discharge mechanism that discharges the card tray 161 inserted into the card connector 1 . The push rod 22 is a linear rod-shaped or strip-shaped member, and a curved operation portion 22a is integrally connected to the rear end portion. A joint portion 22b is formed at the front end portion of the push rod 22 to engage the force point portion 21b of the discharge lever 21. The discharge lever 21 is a lever-like member provided in the vicinity of the inner wall portion 11a and serving as a tray discharge lever of the tray discharge mechanism. As a result, the discharge lever 21 is pivotally attached to the bottom wall portion 11b at the fulcrum portion 21c. The opposite end portion 21b is the action point portion 21a at the other end portion of the fulcrum portion 21c, and the action point portion 21a contacts the insertion card connector. The front frame portion 165 of the card tray 161 in the connector 1 applies a force in the discharge direction to the card tray 161.

The base 11 includes a movable element 57 of the detecting switch and a fixing member 58 for detecting whether a card tray 161 inserted into the card connector 1 has reached a predetermined position (when a card 101 is received in the card tray) The inner card tray 161 is held by the holding elastic member 25 and the top portion 51c of each terminal 51 is in contact with the corresponding electrode pad on the card 101). Since the movable member 57 and the fixed member 58 are in contact when the card tray 161 does not reach the predetermined position, the detecting switch is turned on or activated. However, when the card tray 161 reaches the predetermined position, the movable member 57 contacts and presses against the front frame portion 165 of the card tray 161, and this causes the movable member 57 to be displaced and causes the movable member 57 to be separated from the fixed member 58. Since the detecting switch is no longer turned on and off, it is detected that the card tray 161 exists at a predetermined position.

The following is an explanation of the operation of the card connector 1 having such a structure. First, the operation performed by inserting the card tray 161 will be explained.

Figure 5 is a set of views for explaining a change in contact state between the card and the connector of the card connector in the first embodiment of the present invention. 5A to 5D are side cross-sectional views of the respective steps, and FIGS. 5E to 5H are partially enlarged cross-sectional views taken along line C-C of FIGS. 5A to 5D.

Referring to FIG. 2D and FIG. 3, the user manually inserts a card tray 161 for accommodating a card 101 as a card module 102 into the card connector 1 via the insertion port 18. This Here, the card tray 161 is correctly inserted, that is, the upper surface faces upward toward the top plate portion 62 of the casing 61, the lower surface faces downward toward the bottom wall portion 11b of the susceptor 11, and the front frame portion 165 faces the front end portion 11f of the susceptor 11. The card 101 accommodated in the card housing recess 166 is also correctly disposed, that is, the inner surface 111b faces upward and the surface with the electrode pad faces downward and is exposed on the lower surface of the card tray 161. The card tray 161 can insert and discharge the card connector 1 regardless of whether or not the card tray 161 accommodates a card 101 or does not accommodate a card 101. In the following description, the card tray 161 houses a card 101.

Referring to Fig. 3, when the user inserts the card tray 161 further into the insertion opening 18, the card tray 161 moves toward the front end portion 11f in the card insertion space formed between the casing 61 and the base 11 and reaches a predetermined position. . At this time, more specifically, each of the terminals 51 contacts the card 101 and is gradually deformed as shown in FIGS. 5A to 5D. In FIGS. 5A to 5D, in the present specification, the card tray 161 has been omitted and only the card 101 is shown for the sake of convenience. In FIGS. 5A to D, the insertion direction of the card 101 is the rightward direction.

First, as shown in Figs. 5A to 5D, the lower end of the front end 111f of the card 101 contacts one oblique side portion 51e (the rear end portion 11r side) of the arm portion 51b of the terminal 51 (see Fig. 4B). As described above, the front portion 51b3 of the arm portion 51b is located above the upper surface of the bottom wall portion 11b and the oblique portion 51e exists over the entire range of the front portion 51b3. As a result, the lower end of the front end 111f of the inserted card 101 always contacts the oblique side portion 51e on the side of the rear end portion 11r while the lower surface is traveling along the upper surface of the bottom wall portion 11b.

Next, when the card 101 travels toward the front end portion 11f, the front of the card 101 The lower end of the end 111f travels while maintaining the beveled portion 51e on the side of the rear end portion 11r (see Fig. 4B). In other words, the lower end of the front end 111f of the card 101 slides on the oblique side portion 51e. As shown in FIGS. 5B and 5F, the front portion 51b3 of the arm portion 51b is further depressed and further elastically displaced.

Next, when the card 101 further travels toward the front end portion 11f, the lower end of the front end 111f of the card 101 further slides along the oblique portion 51e on the side of the rear end portion 11r. As shown in FIGS. 5C and 5G, the front portion 51b3 of the arm portion 51b is further depressed and further elastically displaced.

Next, when the card 101 further travels toward the front end portion 11f, as shown in FIGS. 5D and 5H, the lower end of the front end 111f of the card 101 slides over the top portion 51c and the top portion 51c slides along the downwardly facing surface of the card 101. The front portion 51b3 of the arm portion 51b is no longer displaced downward. As shown in FIGS. 5D and 5H, even when the card 101 into which the current side portion 51b3 is inserted is displaced downward, the arm portion 51b is located above the lower surface of the bottom wall portion 11b and does not protrude below the lower surface. Thereby, even when the lower surface of the arm portion 51b contacts the upper surface of the substrate, the conductive trace exposed on the surface of the substrate is not contacted and no short circuit occurs.

Referring to Fig. 3, when the card tray 161 reaches the predetermined position, the holding convex portions 25a of the pair of right and left holding elastic members 25 engage the holding concave portions 168 of the card tray 161. Thus, as shown in FIG. 1, the card tray 161 is stably held and locked at a position corresponding to the predetermined position and cannot be displaced rearward. When the card tray 161 reaches a position corresponding to the predetermined position, the action point portion 21a of the discharge lever 21 is pressed against the front frame The portion 165 interferes with the inner wall portion 11a of the susceptor 11. As a result, the card tray 161 cannot travel further forward.

When the card tray 161 reaches the predetermined position, the movable member 57 of the detecting switch moves away from the fixing member 58. Since this action causes the detection switch to be turned off, it is detected that the card tray 161 exists at a predetermined position.

The following is an explanation of the operation of the card tray 161 to discharge the card connector 1.

Referring to FIG. 3, FIG. 4A and FIG. 4B, first, the user operates an auxiliary component (such as a needle or a lever), and the auxiliary component is inserted into a through hole 163a formed in the rear plate portion 163 from the rear of the card tray 161, and is assisted. The front end of the element contacts the operation portion 22a of the push rod 22. When the user manually pushes the push rod 22 by the auxiliary member, the force point portion 21b of the discharge lever 21 engaged with the engaging portion 22b of the push rod 22 is displaced. As a result, the action point portion 21a of the discharge lever 21 pushes against the front frame portion 165, and the card tray 161 is displaced rearward from the predetermined position. Since the holding convex portion 25a of the holding elastic member 25 is disengaged from the holding concave portion 168 of the card tray 161 and unlocked, the push rod 22 is mainly received by the holding elastic member 25 via the card tray 161 and the discharge lever 21. The resistance caused by the elastic action. However, this resistance is not greater than the pressure exerted by the user's fingers, and the pusher 22 continues to travel forward against this resistance. The detection switch is turned on, and it is detected that the card tray 161 is retracted from the predetermined position.

At this time, the rear plate portion 163 of the card tray 161 protrudes sufficiently from the insertion opening 18 of the card connector 1. As a result, the user can manually grasp the rear plate portion 163 and the card The card connector 1 is removed by the tray 161.

The following is a description of a case where a card tray 161 for accommodating a card 101 of the card module 102 is inserted into the card connector 1 in an inclined posture.

6A to 6F are a set of views showing a specific example of a terminal of the card connector in the first embodiment of the present invention; and FIGS. 7A to 7F are a set of views showing a comparative example. A specific example of the terminal of the card connector; FIG. 8 is a set of views showing a state of contact between a card and a specific example of a terminal of a card connector in the first embodiment of the present invention; 9 is a set of views showing the state of contact between a card and the terminals of a card connector in the comparative example. 6A to 6F and 7A to 7F, FIGS. 6A and 7A are perspective views of the arm portion of the terminal, FIGS. 6B and 7B are a plan view of the arm portion of the terminal, and FIGS. 6C and 7C are terminal portions. A side view of the arm, FIGS. 6D and 7D are rear views of the arm of the terminal, FIGS. 6E and 7E are cross-sectional views taken from line DD of FIGS. 6C and 7C, and 6F and FIG. 7F are terminals. The arm is deformed into a flat top view. In FIGS. 8A to 8D and FIGS. 9A to 9D, FIGS. 8A and 9A are top views showing the arm portions contacting the terminals when the card is not tilted; FIGS. 8B and 9B are the EEs from FIGS. 8A and 9A. Fig. 8C and Fig. 9C are plan views showing the arm portions contacting the terminals when the card is tilted; and Figs. 8D and 9D are cross-sectional views taken from the FF line of Figs. 8C and 9C.

Here, a specific example of one terminal shown in FIGS. 6A to 6F is compared with the comparative example shown in FIGS. 7A to 7F to explain the performance of the terminal 51 in the present embodiment. The specific example is an example of the terminal 51 in the present embodiment, but the terminal 51 in the present embodiment is not limited to this specific example.

In the plan view of the terminal 51 in the present embodiment, the inclination angle of the oblique side portion 51e with respect to the center line of the arm portion 51b (the insertion direction of the card tray 161 and the card 101 indicated by the arrow G) It is preferably 35 degrees or more. However, in the specific example shown in FIG. 6B, the magnitude of the tilt angle is 35 degrees. When the terminal 51 is viewed from the rear of the center line of the arm portion 51b, the inclination angle of the oblique portion 51e with respect to the upper surface of the bottom wall portion 11b is preferably 35 degrees or more. However, in the specific example shown in FIG. 6C, the magnitude of the tilt angle is 35 degrees. The inclination angle corresponds to the initial inclination angle of the oblique portion 51e when the front end portion 111f of the card 101 illustrated in Fig. 5A slides along the oblique portion 51e.

When the terminal 51 is viewed from the insertion direction indicated by the arrow G, the inclination angle of the oblique portion 51e in the vicinity of the top portion 51c with respect to the upper surface of the bottom wall portion 11b is preferably 45 degrees or more. However, in the specific example shown in FIG. 6D, the magnitude of the tilt angle is 45 degrees. When the curved arm portion 51b is deformed into a flat plate shape which is flush with the base portion 51a, the size of the vertex angle of the top portion 51c (the angle formed by the pair of oblique side portions 51e) is preferably 90 degrees or more in plan view. However, the apex angle is 90 degrees in the specific example as shown in Fig. 6F.

In contrast, in the plane of the terminal 251 of the comparative example, the inclination angle of the oblique portion 251e with respect to the insertion direction indicated by the arrow G is 51 degrees as shown in Fig. 7B. When the terminal 251 is viewed from the rear of the center line of the arm portion 251, the inclination angle of the oblique portion 251e with respect to the upper surface of the bottom wall portion 11b is 35 degrees as shown in Fig. 7C. When from the arrow When the terminal 251 is viewed in the insertion direction indicated by G, the inclination angle of the oblique portion 251e near the top portion 251c with respect to the upper surface of the bottom wall portion 11b is 30 degrees as shown in Fig. 7D. When the curved arm portion 251b is deformed into a flat shape in the same plane as the base portion 251a, the apex angle of the top portion 251c (the angle formed by the pair of oblique side portions 251e) is 71 degrees in plan view as shown in Fig. 7F.

In other words, when viewed from the insertion direction shown in Fig. 6D, in the terminal 51 of the present embodiment, the inclination angle of the oblique portion 51e with respect to the upper surface of the bottom wall portion 11b is larger. However, as shown in FIGS. 6B and 6F, by reducing the inclination angle of the oblique portion 51e and increasing the apex angle of the top portion 51c, the inclination angle of the oblique portion 51e shown in Fig. 6C (i.e., when the front end portion of the card 101) The initial inclination angle of the oblique portion 51e when the 11f slides along the oblique portion 51e is kept relatively small. In contrast, in the terminal 251 of the comparative example, the inclination angle of the oblique portion 251e shown in FIG. 7C (that is, the initial inclination angle of the oblique portion 251e when the front end portion 11f of the card 101 slides along the oblique portion 251e) The inclination angle of the terminal 51 is the same in the embodiment, but as shown in Fig. 7D, the inclination angle of the oblique portion 251e with respect to the upper surface of the bottom wall portion 11b is smaller when viewed from the insertion direction, as shown in Figs. 7B and 7F. It is shown that the inclined angle of the oblique portion 251e is larger and the apex angle of the top portion 51c is smaller.

In the terminal 251 of the comparative example, as shown in FIG. 7E, the base portion 251a of the arm portion 251b is bent at the bent portion 251z and connected to the base portion 251a. When viewed from this side, the arm portion 251b extends straight toward the front end. Thus, in the terminal 251 of the comparative example, the amount of the top portion 251c protruding from the upper surface of the bottom wall portion 11b is substantially equal to the top of the terminal 51. The amount by which 51c protrudes from the upper surface of the bottom wall portion 11b. However, the inclination angle of the portion of the arm portion 251b protruding from the upper surface of the bottom wall portion 11b of the arm portion 251b with respect to the upper surface of the bottom wall portion 11b (i.e., the inclination angle of the oblique side portion 251e near the top portion 251c, as shown in Fig. 7D) It is slightly smaller than the inclination angle of the oblique portion 51e of the terminal 51 in the present embodiment. Further, when viewed from the side, the shape of the arm portion 251b of the terminal 251 in the comparative example includes a curved portion 251z serving as a deflection point.

When a card tray 161 accommodating a card 101 is correctly inserted into the card connector 1 (see FIG. 2D), as shown in FIG. 8A, the card 101 contacts the respective arm portions 51b while the front end 111f is parallel to the arm of the terminal 51. The center line of the portion 51b. However, as shown in FIG. 8C, the dimensional error of the card 101 and/or the card tray 161 and the incorrect operation of the user may cause the front end 111f of the card 101 to obliquely contact the arm portion 51b with respect to the center line of the arm portion 51b of the terminal 51. .

Since the inclination angle of the oblique portion 51e with respect to the upper surface of the bottom wall portion 11b in the terminal 51 of the present invention is large when viewed from the insertion direction, in comparison with Figs. 8D and 8B, it is clearly seen that when the card is When the front end 111f of 101 slides along the oblique portion 51e, the initial inclination angle of the oblique portion 51e does not increase too much. Thereby, when the card 101 travels while the front end 111f slides on the oblique side portion 51e, the resistance does not increase, the front portion 51b3 of the arm portion 51b is easily displaced, and the card 101 can easily travel.

In contrast, when the terminal 251 of the comparative example is viewed from the insertion direction, the inclination angle of the oblique portion 251e with respect to the upper surface of the bottom wall portion 11b is small. Thus, when Figure 9D and When comparing Fig. 9B, it can be seen that as the front end 111f of the card 101 slides on the oblique portion 251e, the initial inclination angle of the oblique portion 251e gradually increases. Thereby, when the card 101 travels while the front end 111f slides on the oblique side portion 251e, the resistance increases, the front portion of the arm portion 251b is difficult to be displaced downward, and the card 101 cannot easily travel.

In other words, when the terminal 51 in the present embodiment is viewed from the insertion direction, the inclination angle of the oblique portion 51e with respect to the upper surface of the bottom wall portion 11b is large, so that the arm portion can be easily made even if the card 101 is in the inclined posture. The front portion 51b3 of the 51b is elastically displaced downward, and the card 101 can be easily advanced. In addition, when the inclination angle is close to 90 degrees, even if the card 101 is in the inclined posture, the inclination angle of the oblique portion 51e at the beginning of the sliding of the front end 111f of the card 101 on the oblique portion 51e does not become large, and When the inclination angle is close to 0 degrees, if the card 101 is in the inclined posture, the inclination angle of the oblique portion 51e at the beginning of the sliding of the front end 111f of the card 101 on the oblique portion 51e becomes extremely large. When the inclination angle of the oblique portion 51e with respect to the upper surface of the bottom wall portion 11b is large when viewed from the insertion direction, it is difficult to be affected by the inclination of the posture of the card 101.

Referring to FIGS. 8A and 9A, in the terminal 51 of the present embodiment, the distance from the position where the front end 111f of the card 101 contacts the oblique portion 51e to the base end of the arm portion 51b is also larger than the corresponding distance of the terminal 251 of the comparative example. Thereby, the arm portion 51b is larger than the terminal 251 of the comparative example in the elastic action length, and the load acting on the arm portion 51b is reduced, and when the card 101 travels, the resistance does not increase, and the elastic action of the arm portion 51b is more reliable. The distance at which the front end 111f of the card 101 slides on the oblique portion 51e is also higher than that of the terminal 251 of the comparative example. The distance is short and thus less susceptible to damage by the card 101.

Referring to FIG. 3, FIG. 4A and FIG. 4C, in the embodiment, the card connector 1 houses an inserted card module 102 having an electrode pad on one surface. The card connector 1 has a base 11 including a bottom wall portion 11b. The plurality of terminals 51 are disposed on the bottom wall portion 11b to contact the electrode pads of the card module 102, and each of the terminals 51 includes: a base portion 51a is held by the bottom wall portion 11b; and a cantilever-type arm portion 51b projects laterally with respect to the insertion direction of the card module 102 when the terminal 51 is viewed from above. The arm portion 51b has a curved portion 51b2 that is shaped to have a curved surface in which the center of curvature is located in a side view, and a pair of oblique side portions 51e that are opposite to the arm portion 51b on both sides of the top portion 51c at the free end. The direction of extension is inclined.

Regardless of whether the card module 102 is inserted or ejected, even if the protruding portion and the corner portion of the card module 102 contact the oblique portion 51e and slide along the oblique portion 51e, the arm portion 51b is not hooked. Thereby, the card module 102 can be smoothly inserted and discharged, the terminal 51 is not damaged or plastically deformed, and the card connector 1 is more reliable. The card tray 161 can be inserted as the card module 102 while accommodating a card 101, or the card tray 161 can be inserted while being empty. When an empty card tray 161 is inserted or ejected, there is a possibility that the front frame portion 165 of the card tray 161 will contact the arm portion 51b. However, since the front frame portion 165 contacts the oblique portion 51e and slides along the oblique portion 51e, the front frame portion 165 does not hook the arm portion 51b.

The arm portion 51b includes a flat plate portion 51b1 connected to the base portion 51a and extending parallel to the upper surface of the bottom wall portion 11b, and a top portion 51c connected to the front of the curved portion 51b2. And a front portion 51b3 located above the upper surface of the bottom wall portion 11b. The shape of the arm portion 51b in the side view does not include the bending point, and the portion connected to the base portion 51a is linearly connected to the base portion 51a. Since the top portion 51c contacts the corresponding electrode pad on the card module 102, when the card module 102 is inserted and ejected, a scratching effect on the surface of the electrode pad by the top portion 51c can be expected, and this cleans the electrode pad. surface. As a result, the terminal 51 and the electrode pad are more reliably turned on. Since the distance from the position of the card module 102 on the arm portion 51b to the base portion 51a is long, the length of the elastic action acting on the arm portion 51b is lengthened and there is no point of deflection. As a result, the bending stress is not concentrated at a single point, the elastic action of the arm portion 51b can be maintained, the contact pressure with the electrode pad can be increased, and the load on the arm portion 51b can be reduced. Even when the card module 102 is inserted in the inclined posture, when the card module 102 moves on the oblique portion 51e, the resistance does not increase, and the front portion 51b3 of the arm portion 51b is easily elastically displaced downward, and the card module 102 Can travel easily.

The oblique portion 51e includes a portion above the upper surface of the bottom wall portion 11b. However, since the inserted card module 102 reliably contacts the bevel portion 51e, the inserted card module 102 slides along the bevel portion 51e without hooking the arm portion 51b.

The arm portion 51b includes an opening portion 51f penetrating the arm portion 51b in the plate thickness direction, and the opening portion 51f has a rhombic shape in which one axis is in the extending direction of the arm portion 51b in plan view. The width dimension of the portion of the arm portion 51b other than the opening portion 51f gradually increases linearly from the free end of the arm portion 51b toward the base portion 51a. Thus, the arm portion 51b can function as an equal-strength beam having a bending stress in the longitudinal direction along the center line. The role.

The following is a description of a second embodiment of the present invention. Components that are structurally identical to the first embodiment are denoted by the same reference numerals and further description of these components is omitted. Description of the same operations and effects as those of the first embodiment is also omitted.

Figure 10 is a pair of views showing a card connector with a housing removed in a second embodiment of the present invention. 10A is a plan view and FIG. 10B is a perspective view.

In the present embodiment, as in the first embodiment, the terminals 51 are arranged in two rows and three rows, that is, in two rows extending in the front-rear direction of the susceptor 11 (in the insertion direction of the card module 102). . However, each row is disposed such that the terminal 51 has a different position with respect to the width direction of the susceptor 11 (in the lateral direction with respect to the insertion direction of the card module 102).

More specifically, as shown in FIG. 10A, the plurality of terminals 51 are disposed such that the distance from the center line Y of the susceptor 11 to the apex 51c of the terminal 51 changes as the terminal 51 approaches the front end portion 11f of the susceptor 11. short. In other words, the plurality of terminals 51 are disposed such that the interval between the apexes 51c of the pair of left and right terminals 51 becomes wider as approaching the rear end portion 11r of the susceptor 11 and approaches the front end portion 11f of the susceptor 11 And narrowed. The center line Y is a straight line extending in the front-rear direction of the susceptor 11 through the lateral center of the susceptor 11, and the two rows of terminals 51 are symmetrically disposed on the left and right with respect to the center line.

Also, for example, each terminal 51 may be provided to be from the center line of the housing 11. The distance from Y to the top portion 51c of the terminal 51 is longer than the terminal 51 near the front end portion 11f of the casing 11. Further, for example, each of the terminals 51 may be provided such that, in the right column, the distance from the center line Y of the casing 11 to the top portion 51c of the terminal 51 is shorter than the terminal 51 close to the front end portion 11f of the casing 11, and In the left column, the distance from the center line Y of the casing 11 to the top portion 51c of the terminal 51 is longer than the terminal 51 close to the front end portion 11f of the casing 11.

In summary, this arrangement may be such that the position of the apex 51c of the terminal 51 in each row varies with respect to the width direction of the susceptor 11.

In the embodiment, the plurality of terminals 51 are arranged in a plurality of rows extending in the insertion direction of the card module 102, and in the rows, the position of the apex 51c of the terminal 51 in the lateral direction is inserted along the card module 102. The direction is different. Since the position of the top portion 51c of the terminal 51 contacting an electrode pad on the card module 102 is different for each of the two terminals 51, when the card module 102 is inserted and discharged, the top portion 51c of each terminal 51 is not the same as the electrode pad. The position slides and the electrode pads are not worn at the same location.

Other structural elements, operations, and effects are the same as those of the first embodiment, and further explanation is omitted.

The following is a description of a third embodiment of the present invention. Components that are structurally identical to the first embodiment and the second embodiment are denoted by the same reference numerals and further description of these components is omitted. Descriptions of the same operations and effects as those of the first embodiment and the second embodiment are also omitted.

Figure 11 is a perspective view showing a card tray and a card connector removed from the casing in a third embodiment of the present invention; and Figure 12 is a plan view showing a third embodiment of the present invention The card connector for the housing removed in the example.

In this embodiment, two types of cards (e.g., a microSD® card or a nanoSIM card) can be selectively used. The SD Card Association (which is a standard setting group for SD® cards) specifies that the microSD® card has a size of 15 mm × 11 mm × 1.0 mm (L × W × D).

Therefore, as shown in FIG. 11, the card module 102 of the present invention has a slightly different shape and front-rear direction from the card module 102 of the first embodiment shown in FIG. 3 and can selectively accommodate one. microSD® card or a nanoSIM card. In all other respects, it is identical to the card module 102 of the first embodiment. For convenience, the card 101 described below is a nanoSIM card 101.

As shown in FIGS. 11 and 12, the susceptor 11 in this embodiment includes a second terminal 65 other than the terminal 51. As in the case of the terminal 51 and the lower case 12, the second terminal 65 is integrally molded by a molding process using an insulating resin such as insert molding or overmolding, and the insulating resin covers the susceptor 11 At least a portion is integral with the at least a portion of the base 11.

In the present embodiment, in addition to the terminal holding recess 11c and the solder tail opening 11d, the bottom wall portion 11b of the susceptor 11 further includes: a second terminal holding recess 11g for accommodating and holding the second terminal 65; Second solder tail opening 11h. The second terminal holding recess 11g and the second solder tail opening 11h are openings that penetrate the bottom wall portion 11b in the thickness direction.

There is a single second terminal holding recess 11g and a single second solder tail opening 11h, and a single row of second terminals 65 are arranged to be aligned in the width direction of the susceptor 11. At least a portion of each of the second terminals 65 is embedded in the bottom wall portion 11b. The contact portion 65c is exposed in the second terminal holding recess 11g, and the tail portion 65d is exposed in the second solder tail opening 11h. Each of the contact portions 65c is biased upward by the elastic action of the second terminal 65 and contacts the corresponding electrode pad on the card 101 held in the card tray 161 in the card connector 1. The tail portion 65d is soldered and electrically connected to a signal line, contact pad or terminal formed on a substrate.

The second terminal 65 is configured to mate with an electrode pad on a microSD® card. In other words, when a microSD® card is the card 101 housed in the card tray 161, the electrode pad provided on the surface of the card 101 contacts the contact portion 65c of the second terminal 65.

In the present embodiment, the arrangement of the terminal holding recess 11c and the solder tail opening 11d is different from the arrangement of the terminal holding recess 11c and the solder tail opening 11d explained in the first embodiment.

The terminal holding recesses 11c in this embodiment are arranged in two rows in which the rows extend in the front-rear direction of the susceptor 11. The three terminals 51 are housed in the respective rows of terminal holding recesses 11c and extend in the front-rear direction of the susceptor 11 in each row.

The solder tail opening 11d in this embodiment is divided into two in the vicinity of the rear end portion 11r of the susceptor 11, but forms a single row extending in the width direction of the susceptor 11. The three tail portions 51d are housed in the respective solder tail openings 11d, and these tail portions 51d form a row extending in the width direction of the susceptor 11.

Since the plurality of tail portions 51d are arranged along the rear end portion 11r of the susceptor 11, it is easy to visually confirm whether or not the solder tail portion 51d has been firmly soldered to the connection pads on the substrate. Also, the tail portion 65d of the second terminal 65 may be disposed along the front end portion 11f of the susceptor 11.

In the present embodiment, as in the second embodiment, the plurality of terminals 51 are arranged in two rows extending in the front-rear direction of the susceptor 11 in the respective rows, and the rows are arranged such that the terminals 51 are located at different positions in the width direction of the susceptor 11. . In other words, the terminal 51 is disposed such that the interval between the apexes 51c of the pair of left and right terminals 51 becomes wider as approaching the rear end portion 11r of the susceptor 11.

As shown in FIG. 12, the interval between the base portions 51a of the pair of left and right terminals 51 held by the bottom wall portion 11b in the width direction of the susceptor 11 (i.e., the interval between the base portions 51a of the pair of left and right terminals 51) ) widens near the rear end portion 11r of the susceptor 11. In FIG. 12, a broken line indicates a portion of the terminal 51 buried in the susceptor 11.

Here, since the tail portion 51d of each terminal 51 extends along the rear end portion 11r of the susceptor 11, the connecting leg portion 51g of each terminal 51 connecting the base portion 51a and the tail portion 51d extends in the front-rear direction and passes closer than the terminal 51. The end portion 11r is between the pair of right and left terminals 51 of the base portion 51a. More specifically, a pair of left and right from the rear end portion 11r The connecting leg portion 51g of the terminal 51 extends in the front-rear direction between the base portions 51a of the pair of left and right terminals 51 that are second from the rear end portion 11r and is third (far closest to the rear end portion 11r) from the rear end portion 11r. A pair of left and right terminals 51 extend between the base portions 51a until reaching the respective tail portions 51d. Similarly, the connecting leg portions 51g of the pair of right and left terminals 51 that are second to the rear end portion 11r extend in the front-rear direction between the base portions 51a of the pair of left and right terminals 51 that are third from the rear end portion 11r until the corresponding Tail 51d. Thereby, the plurality of connecting leg portions 51g are disposed to pass between the rows of the terminals 51 without overlapping in the thickness direction of the bottom wall portion 11b.

Thereby, each terminal 51 is provided such that the interval between the pair of left and right terminals 51 becomes wider as it approaches the rear end portion 11r of the susceptor 11. This ensures that the base portion 51a of each terminal 51 is connected to the sufficient space of the joint leg portion 51g of the tail portion 51d and that the joint leg portion 51g is properly arranged.

Other structural elements, operations, and effects are the same as those of the first embodiment and the second embodiment, and further explanation is omitted.

The invention is not limited to the above embodiments. Many variations are also possible based on the spirit of the invention and these do not depart from the scope of the invention.
