All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The present application is directed to a ZIF connector 100 (i.e., a zero insertion force connector) that is intended to improve the reliability of the ZIF connector 100. The ZIF connector 100 can be applied to an electronic device, and it is understood that the electronic device can be, but not limited to, a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), an e-book reader, an MP3 (motion Picture Experts Group Audio Layer III) player, an MP4 (motion Picture Experts Group Audio Layer IV) player, a notebook computer, a car computer, a set-top box, a smart tv, a wearable device, a navigator, a handheld game console, etc.
The specific structure of the ZIF connector 100 of the present application will be described as follows:
as shown in fig. 1 to 5, in an embodiment of the ZIF connector 100 of the present application, the ZIF connector 100 includes:
the connector comprises a connector body 20, wherein an accommodating cavity 100a is formed in the connector body 20, a socket 20b communicated with the accommodating cavity 100a is formed in the surface of the connector body 20, and a golden finger 80 is arranged on the side wall of the accommodating cavity 100 a;
and the locking and releasing mechanism 40 is movably arranged on the side wall of the accommodating cavity 100a, and is used for locking or releasing the flexible circuit board 200 inserted from the interface 20 b.
The ZIF connector 100 will be described below as an example in which it is placed horizontally:
in the present embodiment, the connector body 20 is substantially rectangular, and includes a body 24, an upper cover 22 covering the top surface of the body 24, and a lower cover 26 covering the bottom surface of the body 24, that is, the body 24 is clamped between the upper cover 22 and the lower cover 26. Further, a receiving groove 242 is concavely provided on the top surface of the body 24, a side wall of the receiving groove 242 communicates with the side surface of the body 24 and forms a socket 20b, and the socket 20b is used for inserting the plug portion of the flexible circuit board 200; at this time, the upper cover 22 covers the top surface of the body 24, and encloses with the body 24 to form an accommodating cavity 100a, and the accommodating cavity 100a is used for accommodating the plug portion of the flexible circuit board 200; moreover, a plurality of golden fingers 80 are convexly disposed on the bottom wall of the accommodating groove 242, each golden finger 80 is disposed along the depth direction of the socket 20b, and the plurality of golden fingers 80 are spaced and arranged side by side along the length direction of the socket 20 b. When the plug portion of the flexible circuit board 200 is inserted into the accommodating cavity 100a through the socket 20b, the gold fingers of the plug portion of the flexible circuit board 200 and the gold fingers 80 of the bottom wall of the accommodating groove 242 are in one-to-one correspondence and are abutted against each other, so that the flexible circuit board 200 is electrically connected to the ZIF connector 100.
Further, the bottom wall of the accommodating groove 242 (i.e., the side wall of the accommodating cavity 100 a) is movably provided with a locking and releasing mechanism 40, and the locking and releasing mechanism 40 is movable relative to the bottom wall of the accommodating groove 242 (i.e., the side wall of the accommodating cavity 100 a) and has a locking position and a releasing position: when the locking and releasing mechanism 40 is located at the locking position, it can lock the plug portion of the flexible circuit board 200 inserted from the socket 20b, so as to improve the stability of the connection between the flexible circuit board 200 and the connector body 20 and prevent the flexible circuit board 200 from moving or falling off while ensuring the electrical connection between the flexible circuit board 200 and the connector body 20; when the locking and releasing mechanism 40 is located at the releasing position, it can release the plug portion of the flexible circuit board 200 accommodated in the accommodating cavity 100a, so that the plug portion of the flexible circuit board 200 can be pulled out from the accommodating cavity 100 a. In particular, the lock release mechanism 40 may be a retaining mechanism, such as a retaining head: the abutting head is telescopically arranged on the side wall of the accommodating cavity 100a opposite to the golden finger 80, and when the abutting head extends out relative to the side wall of the accommodating cavity 100a and reaches a locking position, the abutting head can abut against the upper surface of the plug part of the flexible circuit board 200 inserted from the insertion port 20b to abut against and lock the plug part; when the holding head retracts relative to the side wall of the accommodating cavity 100a and returns to the release position, the holding lock of the holding head on the upper surface of the plug part can be cancelled, and the plug part is released. In addition, in order to cooperate with the abutting head, a corresponding driving mechanism 60 and a limit locking mechanism may be further configured on the connector mother body 20, the driving mechanism 60 (e.g., a push rod, a push button, etc.) may be used to drive the locking and releasing mechanism 40 to move, and the limit locking mechanism (e.g., a screw locking mechanism, an urging mechanism, etc.) may be used to maintain the locking position or the releasing position of the locking and releasing mechanism 40. Of course, the locking and releasing mechanism 40 may also be other reasonable and effective structures such as a retaining mechanism, and will not be described in detail herein.
Therefore, it can be understood that, according to the technical solution of the present application, by providing the receiving cavity 100a in the connector body 20 and opening the socket 20b communicating with the receiving cavity 100a on the surface of the connector body 20, the plug portion of the flexible circuit board 200 can be inserted into the receiving cavity 100a through the socket 20b or pulled out of the receiving cavity 100a through the socket 20 b; moreover, the golden fingers 80 are arranged on the side wall of the accommodating cavity 100a, so that the golden fingers can be abutted and matched with the golden fingers of the plug part of the flexible circuit board 200 when the plug part of the flexible circuit board 200 is inserted into the accommodating cavity 100a, and the flexible circuit board 200 is electrically connected with the ZIF connector 100. Further, according to the technical scheme of the application, the locking and releasing mechanism 40 is movably arranged on the side wall of the accommodating cavity 100a, so that the flexible circuit board 200 inserted in the accommodating cavity 100a can be locked and released, when the flexible circuit board 200 is required to be connected with the ZIF connector 100, the ZIF connector 100 can effectively prevent the flexible circuit board 200 from moving or dropping out, and when the flexible circuit board 200 is required to be disconnected with the ZIF connector 100, the flexible circuit board 200 can be released by the ZIF connector 100 to be easily pulled out. That is, the technical scheme of this application provides a neotype ZIF connector 100, can realize locking and the release to flexible circuit board 200 through the locking-releasing mechanism 40 that sets up in holding chamber 100a, has replaced the "piano lid" structure among the correlation technique, has avoided "piano lid" structure to drop after frequent upset and has caused the condition that the connector became invalid to ZIF connector 100's reliability has been promoted.
As shown in fig. 3 to 5, the lock release mechanism 40 may take the following structural form:
the locking and releasing mechanism 40 includes one or more positioning columns 42, the positioning columns 42 are slidably disposed on the side wall of the accommodating cavity 100a and have a first position and a second position, and the positioning columns 42 slide between the first position and the second position to be clamped into the notches on the side edges of the flexible circuit board 200 or to be separated from the notches on the side edges of the flexible circuit board 200.
Specifically, the axis of the positioning column 42 is disposed in the vertical direction, i.e., perpendicular to the (flat plate-like) plug portion of the flexible circuit board 200; meanwhile, the sliding direction of the positioning column 42 is set in the horizontal direction and is set perpendicular to the depth direction of the socket 20b (i.e., the insertion direction of the plug portion of the flexible circuit board 200). Further, a first position of the positioning post 42 may be set as a locking position, and a second position of the positioning post 42 may be set as a releasing position. Correspondingly, a positioning notch 210 is formed on a side of the plug portion of the flexible circuit board 200, and the size of the positioning notch 210 is equal to that of the positioning column 42.
Thus, when the positioning post 42 slides from the second position to the first position, i.e. when the positioning post 42 slides from the releasing position to the locking position, the positioning post 42 can slide into the positioning notch 210 on the side of the plug portion of the flexible circuit board 200 and be clamped in the positioning notch 210, thereby locking the plug portion of the flexible circuit board 200 and preventing the flexible circuit board 200 from moving or coming off; when the positioning post 42 slides from the first position to the second position, i.e. when the positioning post 42 slides from the locking position to the releasing position, the positioning post 42 can be disengaged from the positioning notch 210 on the side of the plug portion of the flexible circuit board 200, thereby releasing the plug portion of the flexible circuit board 200, and the plug portion of the flexible circuit board 200 can be pulled out from the accommodating cavity 100 a.
It can be understood that, the sliding of the positioning column 42 is utilized to lock and release the plug portion of the flexible circuit board 200, so that the stability and reliability are high, the structure is simple, the processing and the manufacturing are convenient, and the assembly is rapid.
Further, on the basis of the above-mentioned structural design for locking or releasing the flexible circuit board 200 by using the positioning column 42 to slide, in order to effectively improve the stability of the locking and releasing mechanism 40 for locking the flexible circuit board 200, the following form may be adopted when the locking and releasing mechanism 40 is actually applied:
the locking and releasing mechanism 40 includes two positioning posts 42, the two positioning posts 42 are spaced apart along the length direction of the socket 20b, and one positioning post 42 slides between the first position and the second position thereof to be close to or far away from the other positioning post 42.
Specifically, the two positioning columns 42 are slidably disposed on the sidewall of the accommodating cavity 100a, and the distance between the two positioning columns and the socket 20b is equivalent. The sliding directions of the two positioning posts 42 are both parallel to the plane of the socket 20 b. Correspondingly, the two sides of the plug portion of the flexible circuit board 200 are both provided with positioning notches 210, and the size of the positioning notches 210 is equal to the size of the positioning columns 42. Thus, when the two positioning columns 42 are located at the first position (locking position), the two positioning columns 42 can be respectively clamped in the two positioning notches 210, so that the plug part of the flexible circuit board 200 can be locked more stably, and the flexible circuit board 200 can be prevented from moving or falling off more effectively; when the two positioning posts 42 are located at the second position (release position), each positioning post 42 can be disengaged from the corresponding positioning notch 210, so as to release the plug portion of the flexible circuit board 200, and the plug portion of the flexible circuit board 200 can be pulled out from the accommodating cavity 100 a.
As shown in fig. 4 and 5, a sliding groove 244 arranged along the length direction of the insertion port 20b is formed in a side wall of the accommodating cavity 100a, one end of the positioning column 42 is inserted into the sliding groove 244, and the other end is accommodated in the accommodating cavity 100 a.
Specifically, the lower ends of the two positioning pillars 42 are inserted into the sliding groove 244, and the upper ends of the two positioning pillars 42 are protruded toward the accommodating cavity 100 a. The width of the slide groove 244 corresponds to the width of the positioning post 42. It can be understood that, the structural design that the positioning column 42 slides in the sliding groove 244 can realize the reasonable planning of the sliding path of the positioning column 42, and the sliding stability of the positioning column 42 is improved, so that the running stability of the locking and releasing mechanism 40 is effectively improved, and the locking function and the releasing function of the locking and releasing mechanism 40 on the flexible circuit board 200 are effectively ensured.
As shown in fig. 4 and 5, in order to realize the operation of the lock release mechanism 40, that is, the locking function and the releasing function of the lock release mechanism 40, the ZIF connector 100 of the present application may be further configured as follows:
a mounting cavity 100b is further formed in the connector parent body 20, the mounting cavity 100b and the accommodating cavity 100a are arranged at an interval, and a through hole 248 communicated with the mounting cavity 100b is formed in the bottom wall of the sliding chute 244;
the ZIF connector 100 further includes a driving mechanism 60, wherein the driving mechanism 60 is at least partially disposed in the mounting cavity 100b and connected to one end of the positioning post 42 inserted into the sliding groove 244, so as to drive the two positioning posts 42 to approach or separate from each other.
In this embodiment, the bottom surface of the body 24 of the connector body 20 is concavely provided with a mounting groove 246, and the lower cover 26 covers the bottom surface of the body 24 and encloses with the body 24 to form a mounting cavity 100 b. At this time, the installation cavity 100b and the accommodating cavity 100a are arranged at an interval in the vertical direction, the installation cavity 100b is located below the accommodating cavity 100a, and the installation cavity 100b is used for installing at least part of the driving mechanism 60, so as to achieve storage and protection of the driving mechanism 60. Further, a through hole 248 communicating with the mounting cavity 100b is opened in the bottom wall of the sliding groove 244, and the through hole 248 is also arranged along the length direction of the insertion port 20b, i.e. along the sliding direction of the positioning column 42. In this way, the driving mechanism 60 can be connected to one end of the positioning post 42 inserted into the sliding slot 244 through the through hole 248, so as to drive the two positioning posts 42 to approach or move away from each other. It can be understood that when the two positioning columns 42 are close to each other and both are located at the first position, the locking of the flexible circuit board 200 can be achieved; when the two positioning posts 42 are far away from each other and both are located at the second position, the flexible circuit board 200 can be released.
Specifically, the driving mechanism 60 may be a combination structure of two keys and an elastic member; at this time, one end of each key may penetrate through the lower cover 26 of the connector body 20 and be inserted into the mounting cavity 100b, and the other end may protrude from the lower surface of the lower cover 26. Moreover, one end of each key inserted into the mounting cavity 100b may be configured as a guiding inclined surface, and correspondingly, one end of each positioning post 42 inserted into the sliding groove 244 may also be configured as a guiding inclined surface, and the guiding inclined surface of each key is attached to the guiding inclined surface of one positioning post 42. Thus, when the key is pressed, one positioning column 42 can be smoothly driven to be far away from the other positioning column 42 through the pushing action of the two guide inclined surfaces; and pressing both keys simultaneously drives the two positioning posts 42 away from each other. Further, an elastic member can be associated between the two positioning posts 42, so that the two positioning posts 42 can be close to each other under the action of elastic restoring force after the two keys are released. Therefore, the two positioning columns 42 can be close to or far away from each other, and further the flexible circuit board 200 can be locked and released.
Of course, in other embodiments, the driving mechanism 60 may also be in other reasonable and effective structural forms, such as a combination structure of a motor, a gear and a rack, a combination structure of a cylinder and a push rod, and the like, and since those skilled in the art can reasonably implement the technical effects and the technical principles described in the text of this application, the details are not repeated here.
In practice, the driving mechanism 60 may be configured as follows, as shown in fig. 4 and 5:
the driving mechanism 60 includes a first transmission arm 62 and a second transmission arm 64, one end of the first transmission arm 62 is disposed on a side of the sliding groove 244 away from the accommodating cavity 100a and connected to one of the positioning pillars 42 to drive the positioning pillar 42 to approach or depart from another positioning pillar 42; one end of the second transmission arm 64 is disposed on a side of the sliding groove 244 away from the accommodating cavity 100a, and is connected to another positioning column 42 to drive the positioning column 42 to approach or depart from another positioning column 42.
Specifically, one end of the first driving arm 62 may be inserted into the mounting cavity 100b through an outer sidewall of the body 24 of the connector body 20, and the other end may protrude from the outer sidewall of the body 24 of the connector body 20. Moreover, one end of the first transmission arm 62 inserted into the mounting cavity 100b may be disposed on one side of the sliding groove 244 away from the accommodating cavity 100a, and is connected to one end of the positioning column 42 inserted into the sliding groove 244. At this time, the first transmission arm 62 may be disposed along the length direction of the socket 20b, and drives the positioning column 42 to move by virtue of the telescopic motion; the first transmission arm 62 may also be disposed along the plugging direction of the flexible circuit board 200, and drives the positioning column 42 to move by virtue of the translational motion. On the other hand, the second transmission arm 64 may be configured similarly to the first transmission arm 62, and is not described herein again.
Thus, the two positioning columns 42 are driven by the two transmission arms respectively, so that the stability of the moving process of the positioning columns 42 can be increased, and the stability and the reliability of the operation of the locking and releasing mechanism 40 are improved.
Further, as shown in fig. 1, 2, 4 and 5, the driving mechanism 60 can be further optimized as follows:
the connector body 20 has a first surface 20a and a second surface 20c which are oppositely arranged, the first surface 20a is provided with the socket 20b, and the second surface 20c is provided with a yielding hole 20d communicated with the mounting cavity 100 b;
one end of the first transmission arm 62, which is away from the positioning column 42, is rotatably connected with one end of the second transmission arm 64, which is away from the positioning column 42; the driving mechanism 60 further includes a push rod 66, one end of the push rod 66 is located outside the connector parent body 20, and the other end of the push rod 66 penetrates through the clearance hole 20d and abuts against one end of the first transmission arm 62 departing from the positioning column 42, so as to drive one end of the first transmission arm 62 departing from the push rod 66 and one end of the second transmission arm 64 departing from the push rod 66 to be away from or close to each other.
Thus, when the push rod 66 is pushed into the mounting cavity 100b, the push rod 66 can drive the first transmission arm 62 and the second transmission arm 64 to rotate relatively and expand, so that the end of the first transmission arm 62, which is far away from the push rod 66, and the end of the second transmission arm 64, which is far away from the push rod 66, are far away from each other; at this time, the positioning column 42 connected to the end of the first transmission arm 62 away from the push rod 66 can be separated from the positioning column 42 connected to the end of the second transmission arm 64 away from the push rod 66, so as to release the flexible circuit board 200; when the push rod 66 is pulled out of the mounting cavity 100b, the push rod 66 can drive the first transmission arm 62 and the second transmission arm 64 to rotate relatively and contract, so that one end of the first transmission arm 62, which is far away from the push rod 66, and one end of the second transmission arm 64, which is far away from the push rod 66, are close to each other; at this time, the positioning column 42 connected to the end of the first transmission arm 62 away from the push rod 66 can be close to the positioning column 42 connected to the end of the second transmission arm 64 away from the push rod 66, so as to lock the flexible circuit board 200.
It can be understood that, with the above configuration, the push rod 66 can drive the two transmission arms to move simultaneously, so as to drive the two positioning pillars 42 to move simultaneously, thereby effectively improving the convenience of operation of the driving mechanism 60 and the locking and releasing mechanism 40.
It should be noted that, under the above setting, a locking structure may be further disposed between the push rod 66 and the body 24 of the connector mother body 20, so as to maintain the positions of the push rod 66 and the locking and releasing mechanism 40 when the push rod 66 is pulled outwards to lock the flexible circuit board 200 by the locking and releasing mechanism 40, thereby improving the stability of the flexible circuit board 200 being locked. Specifically, the locking structure may be a screw, a clip, a buckle, or the like, so as to lock the sidewall of the push rod 66, thereby controlling the insertion depth of the push rod 66 and further controlling the distance between the two positioning pillars 42.
Moreover, in order to further improve the operation convenience of the driving mechanism 60 and the locking and releasing mechanism 40 and reduce the operation difficulty of the user, the ZIF connector 100 of the present application may further be optimized as follows:
the driving mechanism 60 further includes an elastic member 68, one end of the elastic member 68 is connected to the end of the first transmission arm 62 departing from the push rod 66, the other end of the elastic member 68 is connected to the end of the second transmission arm 64 departing from the push rod 66, and the elastic member 68 is used for driving the end of the first transmission arm 62 departing from the push rod 66 and the end of the second transmission arm 64 departing from the push rod 66 to approach each other.
Thus, when the push rod 66 is pushed into the mounting cavity 100b, the push rod 66 can drive the first transmission arm 62 and the second transmission arm 64 to rotate relatively and expand, so that the end of the first transmission arm 62, which is far away from the push rod 66, and the end of the second transmission arm 64, which is far away from the push rod 66, are far away from each other; at this time, the positioning column 42 connected to the end of the first transmission arm 62 away from the push rod 66 can be separated from the positioning column 42 connected to the end of the second transmission arm 64 away from the push rod 66, so as to release the flexible circuit board 200; when the push rod 66 is released, the end of the first transmission arm 62 away from the push rod 66 and the end of the second transmission arm 64 away from the push rod 66 can approach each other under the action of the elastic restoring force; at this time, the positioning column 42 connected to the end of the first transmission arm 62 away from the push rod 66 can be close to the positioning column 42 connected to the end of the second transmission arm 64 away from the push rod 66, and the first transmission arm 62 and the second transmission arm 64 rotate relatively to contract, so that the push rod 66 is ejected out, thereby locking the flexible circuit board 200.
Further, the accommodating cavity 100a is flat, and the thickness of the accommodating cavity 100a gradually decreases along the depth direction of the socket 20 b. That is, the inside of the accommodating chamber 100a is vertically arranged to be wide at the outside and narrow at the inside. Thus, by utilizing the contraction trend of the thickness of the accommodating cavity 100a along the depth direction of the socket 20b, the inserted flexible circuit board 200 can additionally obtain a pressing force, so that the abutting stability of the golden finger of the flexible circuit board 200 and the golden finger 80 of the ZIF connector 100 is effectively improved, and the stability of the electrical connection between the flexible circuit board 200 and the ZIF connector 100 is effectively improved.
