Description

Technical Field

[0001] The present application relates to a connector, and in particular to a card connector. Background Art

[0002] When conventional electronic devices (such as notebook computers) transmit electrical signals with a card (such as an SD card), a card connector must be provided on the electronic device to allow the card to be inserted into the card connector so that the electronic device can access the information on the card.

[0003] The existing card connector only allows a single card (such as an SD card) to be inserted. After the single card is inserted, the electronic device will perform electrical signal transmission with the card via the card connector.

[0004] However, since cards have different types (such as SD cards and CF cards) for different usage scenarios, and different types of cards also have different sizes, when designing electronic devices, it is impossible to know the type of card used by the user. Therefore, under the premise of using cards of different types, it is necessary to respectively set up multiple card connectors, which will make it impossible to reduce the size of the electronic device.

[0005] Therefore, the prior art is indeed in need of further providing more improved solutions. Utility Model Content

[0006] In view of the above-mentioned deficiencies of the prior art, the main purpose of this application is to enable the middle partition body to move upward or downward so that a single card connector can accommodate insertion of different types of cards without the need to set up multiple card connectors, thereby achieving the purpose of reducing the size of the electronic device.

[0007] In order to achieve the above purpose, the technical means adopted in this application are mainly to make the card connector include:

[0008] An upper housing having a plurality of upper conductive terminals, each of which protrudes downward from the upper housing;

[0009] A middle partition body, which is arranged at the bottom of the upper shell and forms an upper card insertion slot between the middle partition body and the upper shell;

[0010] An elastic member, which is located at the bottom of the middle partition body and protrudes forward;

[0011] A lower housing, which is disposed at the bottom of the elastic member and forms a lower card insertion slot between the lower housing and the middle partition body, and has a plurality of lower conductive terminals, each of which protrudes upward from the lower housing; and

[0012] Wherein, when the elastic member is pushed against, the middle partition body moves toward the lower shell body.

[0013] In one embodiment, the upper housing comprises:

[0014] upper plate body;

[0015] Two stepped side walls, each protruding downward from two opposite sides of the upper plate body;

[0016] A rear side wall protrudes downward from the rear side of the upper plate body;

[0017] A plurality of through slots each penetrate the upper plate body.

[0018] In one embodiment, each upper conductive terminal protrudes from the rear side of the upper plate body toward the front side of the upper plate body.

[0019] In one embodiment, each upper conductive terminal is embedded near the rear side of the upper plate body and extends from the rear side of the upper plate body toward the middle partition plate body after decreasing in height and then bends upward to extend.

[0020] In one embodiment, the middle partition body comprises:

[0021] a sheet body located near the front side of the upper shell and the lower shell; and

[0022] Two bent plates are respectively arranged in the lower shell body, and extend downwards from two opposite sides of the sheet body one by one and then bend outwards.

[0023] In one embodiment, the elastic member comprises:

[0024] Two elastic sheets, each elastic sheet having a first end and a second end, each elastic sheet extending horizontally from the first end toward the second end, and the side edges of the first end and the second end extending horizontally outwards;

[0025] Two lifting portions, each lifting portion gradually extending upwards toward the second end near the first end;

[0026] Two rebound portions, each rebound portion protrudes forward from the front edge of the second end and extends in an arc shape toward the first end, and after gradually rising upward above the second end, each rebound portion extends horizontally toward the first end; and

[0027] Two folded portions, each folded portion is formed between each elastic sheet and each elastic portion by folding downward from the extended terminal end of each elastic portion and toward the second end;

[0028] Wherein, each lifting portion is bent downward in an arc shape away from the first end to be combined with the horizontal extension of the rebound portion.

[0029] In one embodiment, the elastic member further comprises:

[0030] The limiting part has two ends connected to the second ends respectively.

[0031] In one embodiment, both ends of the limiting portion are bent downward from the second end of one of them, extend horizontally toward the second end of the other one on the opposite side, and bend upward near the second end of the other one to be connected to the second end of the other one.

[0032] In one embodiment, the lower housing comprises:

[0033] lower plate body;

[0034] Two side walls are disposed at the bottom of the lower plate body and extend upward from two opposite sides of the lower plate body;

[0035] A receiving groove is located on a side wall of one of the two side walls;

[0036] The rear wall extends upward from the rear side of the lower plate body.

[0037] In one embodiment, each lower conductive terminal protrudes from the rear side of the lower plate body toward the front side of the lower plate body.

[0038] Through the above-mentioned driving part, when a card is inserted from the lower card insertion slot, the card will be pressed against the middle partition body, and the middle partition body will further apply a downward force to the elastic member, so that the slot space of the upper card insertion slot is enlarged to accommodate the card, and the slot space of the lower card insertion slot will be reduced, and when the card is pulled out of the lower card insertion slot, the middle partition body will return to the preset position due to the elastic force of the elastic member. In this way, when the card connector responds to different types of cards, there is no need to set up multiple card connectors, and different types of cards can be stored and accessed, so that the size of the electronic device can be greatly reduced.

[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] Regarding the preferred embodiment of the card connector 10 of the present application, Figure 1 As shown, the card connector 10 includes an upper cover 11, an upper shell 12, a middle partition 13, an elastic member 14 and a lower shell 15. The upper cover 11 covers the top surface of the upper shell 12. The upper shell 12 has a plurality of upper conductive terminals 120, each of which protrudes downward from the horizontal direction of the upper shell 12. The middle partition 13 is disposed at the bottom of the upper shell 12 and forms an upper card insertion slot Slot1 between the middle partition 13 and the upper shell 12. The elastic member 14 is located at the bottom of the middle partition 13 and protrudes forward. The lower shell 15 is arranged at the bottom of the elastic member 14 and forms a lower card insertion slot Slot2 between the lower shell 15 and the middle partition body 13. The lower shell 15 has a plurality of lower conductive terminals 150. Each lower conductive terminal 150 is arranged on the lower shell 15 and protrudes upward from the horizontal direction of the lower shell 15. When a card is inserted into the upper card insertion slot Slot1, the elastic member 14 will be pushed to move the middle partition body 13 toward the lower shell 15. When the elastic member 14 changes from being pushed to not being pushed, the middle partition body 13 will return to the preset position due to the elastic force of the elastic member 14.

[0047] Through the contact between the card and the above-mentioned elastic member 14, the elastic member 14 presses against the downward movement of the middle partition body 13, or when the card is not in contact with the elastic member 14, the middle partition body 13 is restored to a preset position due to the elastic force of the elastic member 14. In this way, the card connector 10 can be elastically inserted into cards of different sizes, thereby improving the elastic use of the card connector 10, thereby reducing the overall thickness of the card connector 10, and there is no need to set up multiple card connectors additionally, which can also reduce the size of electronic equipment.

[0048] In detail, Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the upper cover 11 has a plate body 110, two opposite side walls 111 and a plurality of through holes 112. The bottom surface of the plate body 110 covers the top surface of the upper shell 12. The two opposite side walls 111 extend downward from two opposite sides of the plate body 110. In addition, the two opposite side walls 111 are located near the rear side of the plate body 110, and each through hole 112 penetrates the rear side near the plate body 110. Specifically, the two opposite side walls 111 are vertically adjacent to the two opposite side sides near the rear side of the plate body 110 to form an accommodating space.

[0049] The upper housing 12 further includes an upper plate 121, two stepped side walls 122, a rear side wall 123, a plurality of through slots 124 and an upper limit member 125. The two stepped side walls 122 gradually extend downward and outward from two opposite sides of the upper plate 121, and the two stepped side walls 122 are located near the front side of the upper plate 121, and the rear side wall 123 extends downward from the rear side of the upper plate 121. Each through slot 124 corresponds one-to-one to each through hole 112 that penetrates the upper plate body 121. Each upper conductive terminal 120 is embedded (insert molding) in one of the slot walls of each through slot 124. The upper limit member 125 extends downward from the front side of the upper plate body 121 toward the rear side. Each upper conductive terminal 120 extends horizontally and downward from the slot wall of each through slot 124 and is formed above the middle partition body 13. Each upper conductive terminal 120 is bent downward in an arc to form an arc-shaped bending portion. The arc-shaped bending portion can abut against the conductive portion of the card inserted in the upper card insertion slot Slot1, so that each upper conductive terminal 120 is exposed in the upper card insertion slot Slot1. Specifically, the arc-shaped bending portion extends from the rear side of the upper plate body 121 toward the middle partition body 13, and then each upper conductive terminal 120 bends upward (i.e., from the direction of the middle partition body 13 toward the upper plate body 121) to extend. In this way, through the bending of each upper conductive terminal 120, an arc-shaped bending portion can be formed at the front end of each upper conductive terminal 120, and the conductive portion of the card is pressed against the arc-shaped bending portion, so that the electrical signal can be transmitted stably. The arc-shaped bending portion is arc-shaped, and is arranged in front and rear through the two opposite side walls 111 and the two stepped side walls 122 mentioned above, so that the upper cover body 11 can be tightly combined with the side wall of the upper shell 12 to form a continuous side wall.

[0050] The middle partition body 13 is arranged between the upper shell 12 and the lower shell 15, and the middle partition body 13 also includes a sheet body 130 and two bent plates 131. The sheet body 130 is located near the front side of the upper shell 12 and the lower shell 15, and each bent plate body 131 is arranged in the lower shell 15. Each bent plate body 131 extends downward from two opposite sides of the sheet body 130 one by one and is bent outward to form a bent plate body bottom surface, and each bent plate body bottom surface extends horizontally backward and is bent upward to form a top portion 132, and the side edge of the bottom surface of each bent plate body (i.e., the side edge away from the sheet body 130) is bent outward and upward to form the top portion 132. Specifically, the two bent plates 131 are L-shaped, and the top portion 132 is formed near the rear side of the upper shell 12 and on the outside of each bent plate body 131.

[0051] The elastic member 14 includes two elastic sheets 140 , two lifting portions 141 , two rebound portions 142 , two inflection portions 143 and a limiting portion 144 . Each elastic sheet 140 has a first end 1400 and a second end 1401, and each elastic sheet 140 extends horizontally from the first end 1400 to the second end 1401. The sides of the first end 1400 and the second end 1401 each have a convex portion extending horizontally outward. Each lifting portion 141 is arranged between the first end 1400 and the second end 1401, and each lifting portion 141 gradually extends upward toward the second end 1401 near the first end 1400. Each rebound portion 142 protrudes forward from the front edge of the second end 1401 (i.e., away from the first end 1400) and extends in an arc shape toward the first end 1400. After each rebound portion 142 is gradually raised upward above the second end 1401, each rebound portion 142 extends horizontally toward the first end 1400, and each inflection portion 143 extends downward from the extension terminal end of each rebound portion 142. And it is folded back toward the second end 1401 to form between each elastic sheet 140 and each rebound portion 142; wherein, each lifting portion 141 is bent downward in an arc shape away from the first end 1400 to combine with the horizontal extension of the rebound portion 142, and the limiting portion 144 is arranged between the second ends 1401 of the two elastic sheets 140, and the two ends of the limiting portion 144 are respectively connected to each second end 1401. Specifically, a through hole is formed in the middle between the first end 1400 and the second end 1401 of each elastic sheet 140, and each lifting portion 141 is located above the through hole. The two ends of the limiting portion 144 are respectively bent downward from the second end 1401 of one of them, and then horizontally extend toward the direction of the other second end 1401 on the opposite side, and are bent upward near the second end 1401 of the other to connect with the other second end 1401. The top of each lifting portion 141 is in one-to-one contact with the bottom surface of the bent plate body. When each lifting portion 141 is subjected to a downward pushing force, each lifting portion 141 and each rebound portion 142 will be compressed and deformed toward the direction of each elastic sheet body 140 due to the middle partition body 13, thereby causing the middle partition body 13 to move downward.

[0052] The lower shell 15 includes a lower plate body 151, two side walls 152, a receiving groove 153 and a rear wall 154. The two side walls 152 extend upward from two opposite sides of the lower plate body 151. The receiving groove 153 is located on one of the two side walls 152 and is close to the rear wall 154. The rear wall 154 extends upward from the rear side of the lower plate body 151. Specifically, the lower plate body 151 is U-shaped. Each lower conductive terminal 150 protrudes forward and upward from the inner concave part of the U-shape. Each lower conductive terminal 150 is embedded in the lower plate body 151 and is lifted and extended from the rear side of the lower plate body 151 toward the direction of the middle partition body 13. After extending in height, each lower conductive terminal 150 is bent and extended downward. In this way, a contact portion can be formed at the front end of each lower conductive terminal 150 through the bending of each lower conductive terminal 150. The contact portion contacts the conductive portion of the card, so that the electrical signal can be stably transmitted.

[0053] In this embodiment, the card connector 10 further includes a lower limit member 16, an elastic member 17, a fixed block 18 and a coupling member 19. The lower limit member 16 is coupled to the lower housing 15. The elastic member 17 is placed in the receiving groove 153, and the elastic member 17 is a coil spring. The bottom of the fixed block 18 is concave upward and covers the top of the elastic member 17, and the fixed block 18 is further coupled to the lower housing 15, and the coupling member 19 is coupled to the top of the fixed block 18. Through the elastic member 17, the card can be easily pushed out from the rear side to the front side.

[0054] In summary, through the above-mentioned elastic member 14, when a card is inserted into the upper card insertion slot Slot1, the card will press against the middle partition body 13, so that the middle partition body 13 compresses the elastic member 14, and the middle partition body 13 moves toward the direction of the lower shell body 15, so that the slot space of the lower card insertion slot Slot2 is compressed, and the slot space of the upper card insertion slot Slot1 will be enlarged to accommodate the card, and when the card is pulled out of the upper card insertion slot Slot1, the middle partition body 13 will return to the preset position due to the elastic force of the elastic member 14. In this way, when the card connector responds to different types of cards, there is no need to set up multiple card connectors, and different types of cards can be stored and accessed, so that the size of the electronic device can be greatly reduced.
