Description

[Technical Field]

[0001] This utility model relates to the field of electrical connectors, and more particularly to a card edge connector for maintaining the vertical insertion state of an electronic card. [Background Technology]

[0002] In the field of connectors, there is an electrical connector including an insulating body, multiple conductive terminals, a rotating ear clip, and a snap-fit ​​spring. The insulating body includes a slot extending along the longitudinal direction and two assembly portions located at both ends of the slot. The multiple conductive terminals are disposed on the insulating body and exposed in the slot. The ear clip is pivotally connected to one of the assembly portions. The ear clip includes a top latch portion and a locking portion located above the top latch portion. The snap-fit ​​spring is installed on the other assembly portion to lock a mating card. During the insertion of the mating card into the slot, the mating card abuts against the top latch portion downwards, causing the ear clip to rotate and engage the mating card. The bottom surface of the slot has two flush protrusions at both ends along the longitudinal direction. The height of the top latch portion is higher than the height of the bottom surface of the slot and flush with the height of the two protrusions. The two protrusions and the top latch portion are used to abut and support the mating card when it is inserted into the slot. However, this solution still has the following problems: the tail of the conductive terminal needs to be soldered to the circuit board at high temperature, and the high temperature may cause the plastic material to deform, causing the insulating body to arch upward in the middle of the longitudinal direction. This results in the two protrusions having different heights, or both protrusions being higher than the top of the top card, or only the protrusion near the ear buckle being higher than the top of the top card. Before inserting the docking card, the ear buckle is rotated open. During the process of inserting the docking card into the slot, the docking card first contacts the top card and then contacts the protrusion. However, because the height of the protrusion is higher than the top card, the docking card cannot fully contact the top card, so the ear buckle cannot rotate to the correct position to lock the docking card. This is not conducive to the automatic locking of the ear buckle when inserting the card.

[0003] Therefore, it is necessary to provide a card edge connector that keeps the electronic card in a vertical insertion state to overcome the above-mentioned defects. [Utility Model Content]

[0004] In view of the problems in the background technology, the purpose of this utility model is to provide a card edge connector that keeps the electronic card in a vertical insertion state.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a card edge connector for docking with an electronic card, comprising: a base, including a main body extending in a left-right direction and a first tower and a second tower disposed at the left and right ends of the main body, the first tower and the second tower being higher than the main body; the main body having a slot communicating with the first tower and the second tower; at least one protrusion protruding upward from the bottom surface of the slot, the protrusion protruding only on the side close to the second tower and away from the first tower; a plurality of conductive terminals disposed on the base, each conductive terminal having a contact portion protruding into the slot, the protrusion being lower than the contact portion; and a lock. A fastener, located in the second tower section, has a locking part for locking an electronic card; an ear clip, rotatably mounted in the first tower section, includes a latching part and a card ejection part arranged opposite each other in the vertical direction. The ear clip has an unlocked state and a locked state. During the process of inserting the electronic card into the slot, the electronic card presses down against the card ejection part, causing the ear clip to rotate from the unlocked state to the locked state. When the ear clip is in the locked state, the latching part and the latching part lock the electronic card together. The position where the card ejection part abuts against the electronic card is higher than the bottom surface of the slot and is set at the same height as the top of the protrusion. The card ejection part and the protrusion together support the electronic card upward so that the electronic card is in a vertical insertion state into the slot.

[0006] Furthermore, the main body includes two sidewalls disposed on the front and rear sides of the slot. The upper surface of the sidewalls is recessed downwards with multiple recesses, which are spaced apart in the left-right direction. The multiple conductive terminals include a row of first terminals and a row of second terminals disposed on each sidewall. The contact portion of the second terminal is higher than the contact portion of the first terminal. For the same sidewall, the row of second terminals is spaced apart in multiple groups in the left-right direction. Each group includes at least one second terminal. Adjacent groups of second terminals are separated by a recess. At least one first terminal is disposed below each recess.

[0007] Furthermore, neither the first terminal nor the second terminal is exposed by the recess.

[0008] Furthermore, each sidewall includes a plurality of first terminal slots and a plurality of second terminal slots. Each first terminal slot penetrates the sidewall near the slot to communicate with the slot. Each second terminal slot penetrates the sidewall near the slot and the sidewall away from the slot. The first terminal is received in the first terminal slot, and the second terminal is received in the second terminal slot and exposed on the outer side of the sidewall. The recessed portion is not aligned with the first terminal slot in the vertical direction.

[0009] Furthermore, the plurality of conductive terminals include a row of first terminals and a row of second terminals disposed on each sidewall. The contact portion of the second terminal is higher than the contact portion of the first terminal. For the same sidewall, the row of second terminals is arranged in multiple groups along the left-right direction. Each group includes at least one second terminal. Adjacent groups of second terminals are spaced apart. The width of the protrusion in the left-right direction is less than the distance between any two adjacent groups of second terminals in the left-right direction.

[0010] Furthermore, the plurality of conductive terminals include a row of first terminals and a row of second terminals disposed on each sidewall, wherein the contact portion of the second terminal is higher than the contact portion of the first terminal, and the protrusion is offset from the first terminal and the second terminal in the front-back direction.

[0011] Furthermore, the height between the top of the protrusion and the bottom surface of the slot is 0.05mm-0.2mm.

[0012] Furthermore, the height between the top of the protrusion and the bottom surface of the slot is 0.1 mm.

[0013] This utility model also discloses a card edge connector for interfacing with an electronic card, comprising: a base, including a main body extending in a left-right direction and a first tower and a second tower disposed at the left and right ends of the main body, both the first tower and the second tower being higher than the main body; the main body having a slot communicating with the first tower and the second tower; at least one protrusion and at least one raised portion protruding upward from the bottom surface of the slot; the at least one protrusion being located on the side of the slot closer to the second tower and farther from the first tower, and the at least one raised portion being located on the side of the slot closer to the first tower and farther from the second tower; the height of the protrusion being higher than the height of the raised portion; and a plurality of conductive terminals disposed on the base, each conductive terminal having a protrusion extending into the slot. The device comprises a contact portion, with the protrusion positioned below the contact portion; a locking element, located in the second tower portion, having a locking portion for locking the electronic card; and an ear clip, rotatably mounted in the first tower portion, including a latching portion and a card ejection portion arranged opposite each other in the vertical direction. The ear clip has an unlocked state and a locked state. During the insertion of the electronic card into the slot, the electronic card presses downward against the card ejection portion, causing the ear clip to rotate from the unlocked state to the locked state. When the ear clip is in the locked state, the latching portion and the latching portion together lock the electronic card. The position where the card ejection portion abuts against the electronic card is higher than the bottom surface of the slot and is set at the same height as the top of the protrusion. The card ejection portion and the protrusion together support the electronic card upward so that the electronic card is in a vertically inserted state into the slot.

[0014] Furthermore, a protrusion is provided, located on the outer side of the conductive terminal near the second tower in the left-right direction.

[0015] This invention features a protrusion on the side near the second tower and away from the first tower, at the same height as the top of the card ejection part of the ear clip. During the insertion of the electronic card into the slot, the card first contacts the card ejection part and then the protrusion. Since the height of the protrusion is equal to that of the card ejection part, after the ear clip rotates to engage the card, the card ejection part and the protrusion together support the card upwards, helping to maintain the card in a vertical insertion position. On the side near the first tower and away from the second tower, there is no protrusion or a protrusion with a lower height. Therefore, when the card edge connector is soldered to the circuit board at high temperature, even if the base deforms, the protrusion will not affect the card ejection part's support for the card. In other words, when the electronic card is inserted into the slot, one end of the card still contacts the card ejection part first, allowing the ear clip to rotate to engage the card.

Detailed Implementation Methods

[0027] To facilitate a better understanding of the purpose, structure, features, and effects of this utility model, the present utility model will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] In this utility model, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0029] like Figures 1 to 8 As shown, this is the first embodiment of the card edge connector 100 of this utility model. Figure 9 The image shows a second embodiment of the card edge connector 100 of this utility model. Both the first and second embodiments are described using a DDR connector as an example, but are not limited to DDR connectors.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, the card edge connector 100 includes a base 1, a plurality of conductive terminals 2 disposed on the base 1, and a locking member 3 and an ear clip 4 disposed on the left and right ends of the base 1. The base 1 is used to accommodate an electronic card 200, and the conductive terminals 2 are used to electrically connect the electronic card 200 and a circuit board (not shown in the figure). The locking member 3 and the ear clip 4 are both used to hold the electronic card 200 when it is inserted into the base 1. Taking the locking member 3 disposed on the right end of the base 1 and the ear clip 4 disposed on the left end of the base 1 as an example, the following description is provided.

[0031] like Figure 1 and Figure 2 As shown, the base 1 includes a main body 1A extending in a left-right direction X, and a first tower 1B and a second tower 1C located at the left and right ends of the main body 1A. Both the first tower 1B and the second tower 1C are higher than the main body 1A. Specifically, the first tower 1B is located at the left end of the main body 1A, and the second tower 1C is located at the right end of the main body 1A. Specifically, the base 1 is integrally molded from plastic material, that is, the main body 1A, the first tower 1B, and the second tower 1C are injection molded in one step. However, in other embodiments, the main body 1A may be separately disposed from the first tower 1B and the second tower 1C. The base 1 may also include an outer shell (not shown in the figure), on which the first tower 1B and the second tower 1C are located, and the outer shell covers the main body 1A.

[0032] like Figure 1 , Figure 4 and Figure 5As shown, the main body 1A includes a slot 11, two side walls 12, and at least one protrusion 13. The two side walls 12 are arranged opposite each other to define the slot 11. The slot 11 connects to the first tower 1B and the second tower 1C in the left-right direction X. The slot 11 is used for inserting an electronic card 200. The protrusion 13 protrudes upward from the bottom surface of the slot 11. Specifically, when the electronic card 200 is inserted into the slot 11, the protrusion 13 contacts and supports the electronic card 200.

[0033] like Figure 4 As shown, the protrusion 13 is provided only on the side near the second tower 1C and away from the first tower 1B. That is, the protrusion 13 is not provided on the side near the first tower 1B. Specifically, only one protrusion 13 is provided, and it is located on the outer side of the conductive terminal 2 near the second tower 1C in the left-right direction X. Of course, in other embodiments, multiple protrusions 13 can also be provided, but multiple protrusions 13 are all limited to the side near the second tower 1C and away from the first tower 1B.

[0034] like Figure 3 , Figure 6 and Figure 8 As shown, each sidewall 12 is provided with multiple recesses 121, multiple first terminal slots 122, and multiple second terminal slots 123. The first terminal slots 122 penetrate only the sidewall 12 near the slot 11 along the front-rear direction Y and communicate with the slot 11. The upper part of the second terminal slot 123 penetrates both the front and rear sides of the sidewall 12 along the front-rear direction Y and communicates with the slot 11, while its lower part penetrates only the sidewall 12 away from the slot 11 along the front-rear direction Y. The number of second terminal slots 123 is less than the number of first terminal slots 122, and each second terminal slot 123 is located in the front-rear direction Y... The upper part of the second terminal slot 123 is aligned with the lower part of the first terminal slot 122. The lower part of the second terminal slot 123 and the lower part of the first terminal slot 122 aligned with it are separated by plastic. The upper part of the second terminal slot 123 and the upper part of the first terminal slot 122 aligned with it are connected in the front-back direction Y. The height of the second terminal slot 123 is higher than that of the first terminal slot 122. For the same side wall 12, there are multiple sets of second terminal slots 123 in the left-right direction X. Each set includes at least one second terminal slot 123. The two adjacent sets of second terminal slots 123 are spaced apart. Each recess 121 is located between two adjacent sets of second terminal slots 123, and each recess 121 is located above a portion of the first terminal slot 122. It can be understood that the recess 121 is used to thin the thickness above a portion of the first terminal slot 122, so that the thickness of the side wall 12 is uniform and the uneven shrinkage of the seat body 1 is balanced.

[0035] like Figure 2 , Figure 4 and Figure 7As shown, the plurality of conductive terminals 2 include a plurality of first terminals 2A and a plurality of second terminals 2B disposed on each sidewall 12. The plurality of first terminals 2A are respectively received in a plurality of first terminal slots 122, and the plurality of second terminals 2B are respectively received in a plurality of second terminal slots 123. Specifically, the first terminals 2A are assembled into the corresponding first terminal slots 122 from bottom to top, and the second terminals 2B are assembled into the corresponding second terminal slots 123 along the front-back direction Y from the side away from the slot 11 to the side closer to the slot 11. Each first terminal 2A and each second terminal 2B has a contact portion 21 protruding into the slot 11. After the electronic card 200 is inserted into the slot 11, the contact portion 21 of the first terminal 2A and the contact portion 21 of the second terminal 2B are both in electrical contact with the electronic card 200. The protrusion 13 is lower than the contact portion 21 of the conductive terminal 2. Specifically, the height of the contact portion 21 of the second terminal 2B is higher than the height of the contact portion 21 of the first terminal 2A, and the protrusion 13 is lower than the height of the contact portion 21 of the first terminal 2A. For the same sidewall 12, a row of second terminals 2B is arranged in multiple groups along the left-right direction X. Each group includes at least one second terminal 2B. Adjacent groups of second terminals 2B are spaced apart. Each recess 121 is located above the first terminal 2A and between two adjacent groups of second terminals 2B. Specifically, neither the first terminal 2A nor the second terminal 2B is exposed by the recess 121. This avoids excessive contact between the first terminal 2A and the second terminal 2B and the air, prevents dust accumulation on the conductive terminal 2, and prevents oxidation-reduction reactions on the conductive terminal 2.

[0036] like Figure 4 As shown, in the first embodiment, the width of the protrusion 13 in the left-right direction X is less than the distance between any two adjacent sets of second terminals 2B along the left-right direction X. Specifically, the protrusion 13 is located at the right end of the slot 11, and the protrusion 13 is offset from the first terminal 2A and the second terminal 2B in the front-back direction Y.

[0037] like Figure 4 , Figure 5 and Figure 7 As shown, the height between the top of the protrusion 13 and the bottom surface of the slot 11 can be within the range of 0.05mm-0.2mm. This design minimizes the distance between the top of the protrusion 13 and the bottom surface of the slot 11, ensuring sufficient sliding distance between the electronic card 200 and the contact portion 21 of the conductive terminal 2 after insertion, without affecting support. This results in better contact between the conductive terminal 2 and the electronic card 200. In this embodiment, the height between the top of the protrusion 13 and the bottom surface of the slot 11 is 0.1mm.

[0038] like Figure 2 and Figure 5As shown, the locking element 3 is a metal spring piece, which is provided in the second tower part 1C. The locking element 3 has a through hole in the left and right sides, which is used to allow a part of the electronic card 200 to be inserted when the electronic card 200 is inserted into the slot 11. A locking part 31 for locking the electronic card 200 is formed at the upper end of the hole.

[0039] like Figure 1 , Figure 4 and Figure 5 As shown, the ear clip 4 is rotatably installed on the first tower part 1B, including a latching part 41 and a card ejection part 42 arranged opposite each other in the vertical direction Z. The ear clip 4 has an unlocked state and a locked state. During the process of inserting the electronic card 200 into the slot 11, the electronic card 200 presses down against the card ejection part 42, causing the ear clip 4 to rotate from the unlocked state to the locked state. When the ear clip 4 is in the locked state, the locking part 31 and the latching part 41 lock the electronic card 200 together. The position where the card ejection part 42 abuts against the electronic card 200 is higher than the bottom surface of the slot 11 and is set at the same height as the top of the protrusion 13. The card ejection part 42 and the protrusion 13 together support the electronic card 200 upward so that the electronic card 200 is in a state of being vertically inserted into the slot 11.

[0040] like Figure 9 As shown, the difference between the second embodiment and the first embodiment is that the main body 1A further includes at least one protrusion 14 protruding from the bottom surface of the slot 11 and located near the first tower portion 1B and away from the second tower portion 1C. The height of the protrusion 14 is less than the height of the protrusion 13, and the protrusion 14 does not serve to support the electronic card 200. The other structures of the second embodiment are the same as those of the first embodiment, and can be referred to the first embodiment, which will not be described again.

[0041] The beneficial effects of this utility model are as follows:

[0042] 1. This utility model provides a protrusion 13, at the same height as the top of the card ejection portion 42 of the ear buckle 4, on the side near the second tower portion 1C and away from the first tower portion 1B. Thus, during the insertion of the electronic card 200 into the slot 11, the electronic card 200 first contacts the card ejection portion 42 and then the protrusion 13. Since the height of the protrusion 13 is equal to that of the card ejection portion 42, after the ear buckle 4 rotates to its position and engages the electronic card 200, the card ejection portion 42 and the protrusion 13 together support the electronic card 200 upwards, which helps to protect the electronic card 200. In the vertical insertion state, on the side closer to the first tower 1B and farther from the second tower 1C, there is no protrusion 13 or a protrusion 14 with a height lower than the protrusion 13. In this way, when the card edge connector 100 is soldered to the circuit board at high temperature, even if the base 1 is deformed, the protrusion 14 will not affect the support of the card ejection part 42 for the electronic card 200. That is, when the electronic card 200 is inserted into the slot 11, one end of the electronic card 200 still contacts the card ejection part 42 first, so that the ear clip 4 can rotate into place and fasten the electronic card 200.

[0043] 2. The second terminal 2B is higher than the first terminal 2A, and a row of second terminals 2B is arranged in multiple groups along the left-right direction X. The two adjacent groups of second terminals 2B are spaced apart from each other. Therefore, a recessed portion 121 for material removal can be provided on the upper surface of the side wall 12 above the first terminal 2A and between the two adjacent groups of second terminals 2B in the left-right direction X. This optimizes the uniformity of the wall thickness of the connector 100 and reduces the deformation problem caused by uneven shrinkage during the cooling process.

[0044] 3. Neither the first terminal 2A nor the second terminal 2B is exposed by the recess 121, thus avoiding excessive contact between the first terminal 2A and the second terminal 2B and the air, preventing dust accumulation on the terminals and preventing oxidation-reduction reactions of the conductive terminals 2.

[0045] 4. The recessed portion 121 is not at least partially overlapped with the first terminal groove 122 in the vertical direction Z, so as to avoid the width of the recessed portion 121 in the front-back direction Y being too wide, so that the wall thickness of the recessed portion 121 near the slot 11 is thinner, that is, to prevent the wall of the recessed portion 121 near the slot 11 from breaking during the injection molding process.

[0046] 5. The width of the protrusion 13 in the left-right direction X is smaller than the distance between any two adjacent sets of second terminals 2B in the left-right direction X. This makes the width of the protrusion 13 smaller, so as to avoid the large range of thermal deformation of the protrusion 13 during the high-temperature welding of the conductive terminal 2, which would cause the top of the protrusion 13 and the position of the card ejection part 42 abutting against the slot 11 to be uneven, thereby affecting the support of the electronic card 200.

[0047] 6. Without changing the depth of the slot 11, the height between the top of the protrusion 13 and the bottom surface of the slot 11 is set in the range of 0.05mm-0.2mm to ensure that the first terminal 2A has stable electrical contact with the electronic card 200.

[0048] 7. The height between the top of the protrusion 13 and the bottom of the slot 11 is 0.1mm. This height can not only support the electronic card 200 well, but also make it easier for the electronic card 200 to press the card ejection part 42 so that the ear buckle 4 can rotate to achieve automatic fastening.

[0049] The above detailed description is only a description of the preferred embodiment of this utility model and is not intended to limit the patent scope of this utility model. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
