[0034] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a connector assembly. The connector assembly includes a first connector 1, a circuit board 2 and an upper cover 3. The connector 1 includes a conductive terminal 11 and a connector body 13. Figure 1 and Figure 2In the embodiment, the conductive terminals 11 constitute a slot 110 located in the vertical direction. The number of rows of conductive terminals is not limited, as long as the electrical connection between the first connector 1 and the circuit board 2 (i.e., the second connector) can be realized to realize the transmission of signals, etc. The connector 1 is, for example, a vertical connector, more specifically, a vertical ZIF (Zero Insertion Force) connector. However, the technician can understand that the purpose of the present application is to lock the second connector as described later, so the first connector 1 can be a horizontal connector, etc. In addition, although the circuit board 2 is used to illustrate in each figure, the circuit board 2 is inserted into the slot 110, but the technician can understand that the circuit board 2 is a type of second connector. The second connector can also be a line board connector, such as a combination of a cable and a connector. The upper cover 3 is assembled with the connector body 13. This assembly can be pre-assembled before leaving the factory, so that the connector 1 and the upper cover 3 are components; or the upper cover 3 and the connector 1 are discrete parts and assembled when used. The upper cover 3 includes a first locking portion 31 for the second connector (circuit board 2). Correspondingly, the second connector (circuit board 2) is provided with a first matching portion 21. The first locking portion 31 and the first matching portion 21 constitute a first locking structure 4, so that the second connector (circuit board 2) and the upper cover 3 are locked by the first locking structure 4 located on the side of the circuit board 2. It should be noted here that the figure schematically shows that the first locking structure 4 (the first locking portion 31 and the first matching portion 21) are located on the side of the second connector (circuit board 2), but its setting position is not limited, as long as the second connector (circuit board 2) and the upper cover 3 can be locked. In addition, the upper cover 3 is also provided with a first retaining portion 321, and the connector body 13 is provided with a second retaining portion 1311. The first retaining portion 321 and the second retaining portion 1311 constitute a retaining structure 5. The retaining structure 5 locks the upper cover 3 with the connector body 13.

[0035] As set up above, since the upper cover 3 of the first connector 1 is locked with the connector body 13 by the retaining structure 5 (the first retaining portion 321 and the second retaining portion 1311), and the second connector (circuit board 2) is locked with the upper cover 3 by the first locking portion 31 and the first matching portion 21 (that is, the first locking structure 4), the connector body 13, the second connector (circuit board 2) and the upper cover 3 are locked as a whole, changing the previous way in which the circuit board 2 is locked by friction. Therefore, after the first connector 1 and the second connector (circuit board 2) are plugged in, the second connector (circuit board 2) is not easy to loosen.

[0036] Based on the respective functions of the first locking structure 4 and the retaining structure 5, technicians can understand that the first locking portion 31 and the first matching portion 21 are not limited to the structure shown in the figure, and the first retaining portion 321 and the second retaining portion 1311 are not limited to the structure shown in the figure.

[0037] exist Figure 1 , Figure 2 and Figure 3 In the embodiment, there are two first locking structures 4, which are located on opposite sides of the second connector (circuit board 2). There are two retaining structures 5, and there are more locking locations on the opposite sides of the second connector (circuit board 2), so the second connector (circuit board 2) is less likely to loosen. Of course, technicians can understand that the number of first locking structures 4 is not limited, and can be one, three, etc. Correspondingly, the number of retaining structures 5 is also not limited, and can be one, three, etc.

[0038] For both vertical connectors and horizontal connectors, the above beneficial effects are achieved. In addition, for the horizontal connector as shown in the figure, when the first connector and the second connector form a connector assembly, the connector assembly occupies a small board area and is suitable for scenarios where the stacking space on the board is small.

[0039] See also Figure 2 , Figure 3 and Figure 4 Combined with Figure 1 The first locking structure 4 includes a first locking portion 31 disposed on the upper cover 3 and a first matching portion 21 disposed on the second connector (circuit board 2). When the second connector (circuit board 2) is plugged into the first connector 1 along the first direction, the first locking portion 31 provides a pressing force in the same direction as the insertion direction of the circuit board to press the first matching portion 21 (that is, the first locking portion 31 presses the first matching portion 21 in the first direction) to lock the second connector (circuit board 2). Figure 2 and Figure 3 FIG. 1 shows that the second connector (circuit board 2) is inserted into the slot 110 in the vertical downward direction to be plugged with the first connector. Then, the first locking portion presses the first mating portion 21 in the vertical downward direction. Figure 2 , Figure 3 and Figure 4 Indicated by the black arrow R1.

[0040] As set up above, the second connector is plugged into the first connector along the first direction, and the first locking portion 31 is pressed against the first matching portion 21 in the first direction, providing a pressing force in the same direction as the insertion direction of the second connector (circuit board 2) to press the first matching portion 21 to lock the second connector (circuit board 2). In this way, the cooperation between the first locking portion 31 and the first matching portion 21 will not affect the insertion of the circuit board 2, making it easier for the second connector (circuit board 2) to be locked, and will not make the structure between the second connector (circuit board 2) and the upper cover 3 complicated.

[0041] See also Figure 1 , Figure 2 and Figure 3 Combined with Figure 4 The first locking portion 31 includes a pressing block disposed on the upper cover 3. The first matching portion 21 includes a matching block located on the side of the second connector (circuit board 2).

[0042] As described above, since the first locking portion 31 includes a pressing block disposed on the upper cover 3, and the first matching portion 21 includes a matching block located on the side of the second connector (circuit board 2), there is no need to add additional parts or processes, and the sizes of the connector 1 and the upper cover 3 are not increased, which can save costs. Moreover, the combination of the pressing block and the matching block also makes locking convenient. It only takes inserting the circuit board 2 to press the pressing block against the matching block to achieve locking. The first locking structure 4 has a simple structure and is convenient for locking.

[0043] See also Figure 1 Combined with Figure 2 and Figure 3 The first retaining portion 321 is located at a side of the upper cover 3, which may be one side or an opposite side. The first connector 1 includes conductive terminals 11. The conductive terminals 11 are arranged in a row on the connector body 13; the connector body 13 includes an end portion, the end portion and the conductive terminals 11 are arranged in a row, and the second retaining portion 1311 is located at the end portion.

[0044] As configured above, the first retaining portion 321 is located on the side of the upper cover 3 and the second retaining portion 1311 is located at the end, which is convenient for locking the upper cover 3 with the connector body 13, and is also located on the insertion path of the second connector (circuit board 2), which is convenient for the second connector (circuit board 2) to be plugged into the first connector 1.

[0045] See also Figure 1 , Figure 2 and Figure 3, the first locking portion 31 is located on opposite sides of the upper cover 3, but the technicians can understand that since the number of the first locking structures 4 is not limited, the first locking portion 31 can be located on at least one side of the upper cover 3. When the first locking portion 31 is located on the side of the upper cover 3, combined with the first retaining portion 321 being located on the side of the upper cover 3 and the second retaining portion 1311 being located at the end, it is convenient for the second connector (circuit board 2) to be plugged into the first connector 1.

[0046] See also Figure 4 Combined with Figure 3 and Figure 1 The end of the connector body 13 of the connector 1 includes a receiving groove 131. The upper cover 3 includes a side arm 32 inserted into the receiving groove 131. The first retaining portion 321 is provided on the side arm 32. The second retaining portion 1311 is provided on the groove wall of the receiving groove 131. The first retaining portion 321 and the second retaining portion 1311 form a wedge-shaped structure, so that the upper cover 3 is inserted into the receiving groove 131 of the connector body 13 along the insertion direction of the second connector (circuit board 2), so that the upper cover 3 is locked with the connector body 13 through the wedge-shaped structure.

[0047] As described above, by setting the wedge-shaped structure, the upper cover 3 is inserted into the receiving groove 131 of the connector body 13 along the insertion direction of the circuit board 2. The more the upper cover 3 is inserted, the more firmly the upper cover 3 and the connector body 13 are locked, until the first locking structure 4 is locked (for example, the pressing block presses against the mating block). Thus, the upper cover 3 and the connector body 13 are firmly locked, and the second connector (circuit board 2) is reliably locked and less likely to loosen.

[0048] See also Figure 4 and Figure 3 The first retaining portion 321 is a protruding portion provided on the side arm 32. The second retaining portion 1311 is a pressing portion provided on the groove wall, and the protruding portion and the pressing portion protrude toward each other to form the wedge-shaped structure. Figure 4 and Figure 3 As shown, the protruding portion protrudes toward the abutting portion (i.e., protrudes toward the outside of the connector), and the abutting portion protrudes toward the protruding portion (i.e., protrudes toward the inside of the connector). The protruding portion abuts against the abutting portion so that the upper cover 3 is locked with the connector body 13. Of course, the structures of the protruding portion and the abutting portion are not limited, as long as one of the protruding portion and the abutting portion protrudes toward the other of the protruding portion and the abutting portion to form a wedge-shaped structure. For example, the protruding portion and the abutting portion are both convex hulls. In other embodiments, the protruding portion and the abutting portion may also be inclined surfaces inclined relative to the horizontal plane.

[0049] As set up as above, since one of the protruding portion and the pressing portion is protruding toward the other of the protruding portion and the pressing portion to form the wedge-shaped structure, the more the upper cover 3 is inserted along the insertion direction of the second connector (circuit board 2), the more firmly the locking between the upper cover 3 and the connector body 13 is, and the tighter the first locking portion 31 on the upper cover 3 and the first matching portion 21 on the second connector (circuit board 2) are locked (for example, in the aforementioned embodiment, the first locking portion 31 presses the first matching portion 21 more tightly), and a greater force is required to unlock the upper cover 3 and the connector body 13, and then unlock the first locking portion 31 and the first matching portion 21, so that the second connector (circuit board 2) is less likely to loosen.

[0050] The first retaining portion 321 and the second retaining portion 1311 are both convex, which not only prevents the circuit board 2 from being easily loosened, but also makes it easier for the first retaining portion 321 and the second retaining portion 1311 to be separated along their respective inclined surfaces, thereby facilitating the upper cover 3 to move between the first position and the second position as described later.

[0051] See also Figure 5 and Figure 4 Combined with Figure 1 , the upper cover 3 can be held in the first position by the retaining structure 5, a blocking structure 6 is provided between the connector body 13 and the upper cover 3, the upper cover 3 can be blocked in the second position by the blocking structure 6, and can move between the first position and the second position. The specific structure of the blocking structure 6 is not limited. In the embodiment of the present application, a hook 322 is formed at the end of the side arm 32, the groove wall includes a connecting wall 1312, the connecting wall 1312 and the second retaining portion 1311 form a step 1313, and the blocking structure includes the hook 322 and the step 1313. When the upper cover 3 moves to the second position, the hook 322 is locked with the step 1313, thereby preventing the upper cover 3 from being separated from the connector body 13.

[0052] As set up above, when the upper cover 3 is maintained in the first position, the first locking structure 4 and the retaining structure 5 cooperate to lock the second connector (circuit board 2). When the second connector (circuit board 2) needs to be inserted, the upper cover 3 is moved from the first position to the second position, and then the second connector (circuit board 2) is inserted. The upper cover 3 is then pressed down to finally complete the insertion of the second connector (circuit board 2). The circuit board 2 is conveniently inserted into the slot 110. In addition, the upper cover 3 can move between the first position and the second position, so that the upper cover 3 and the connector body 13 are always in a connected state as a component. The upper cover 3 will not be separated from the connector body 13, thereby preventing the upper cover 3 from being lost during transportation.

[0053] See also Figure 1 and Figure 2, the upper cover 3 includes an upper cover body 33 and side arms 32. The side arms 32 and the upper cover body 33 enclose a space 34 to limit the second connector. The structure of the space 34 is not limited, and is not limited to the side arms 32 being respectively located at the ends of the upper cover body 33 as shown in the figure, and enclosing a space 34 to limit the circuit board 2 with the upper cover body 33. The first connector 1 includes conductive terminals 11. The conductive terminals 11 are arranged in a row on the connector body 13 to form a contact surface. Normally, the conductive terminals 11 are on the same plane as the part electrically connected to the second connector, and the contact surface is the plane, or the contact surface is understood by means of the aforementioned method. See. Figure 5 Combined with Figure 1 The upper cover body 33 includes a guide wall 331, which is inclined to the abutting surface and forms a guide space with the abutting surface to guide the second connector (circuit board 2) to be plugged with the first connector 1. Figure 5 Combined with Figure 2 and Figure 3 The first connector 1 is a vertical connector, and the second connector (circuit board 2) is inserted in the vertical direction. Therefore, the abutment surface is located in the vertical direction, and the guide wall 331 is inclined to the vertical direction. Figure 5 When the first connector is a horizontal connector, the abutting surface is located on a horizontal plane, and the guide wall 331 is inclined to the horizontal plane, that is, inclined to the horizontal direction.

[0054] As follows, see Figure 5 Combined with Figure 2 , Figure 3 and Figure 4 , describes how to guide the insertion of the second connector (circuit board 2) in this application: the guide wall 331 guides the circuit board 2 during the insertion process of the circuit board 2. More specifically, first lift the upper cover 3 so that the upper cover 3 moves to the second position (that is, the hook 322 is locked with the step 1313, but the protrusion is separated from the pressing part, that is, the retaining structure is unlocked, and the upper cover 3 is unlocked from the connector body 13), then, as Figure 5 As shown, the second connector (circuit board 2) is inserted in a direction inclined to the vertical plane, and then the upper cover 3 is pressed down, so that the second connector (circuit board 2) is guided by the guide wall 331, and turns along the arrow a to become a vertical direction, and finally the second connector (circuit board 2) is plugged into the first connector 1. The state after the second connector (circuit board 2) is plugged in is as shown in FIG. Figure 2 and Figure 3 shown.

[0055] As described above, by providing a guide wall 331 inclined to the abutting surface, the guide wall 331 guides the second connector (circuit board 2), and even if the first locking structure 4 is provided, it is convenient for the second connector (circuit board 2) to be plugged in with the first connector. In particular, combined with the upper cover 3 being able to move between the first position and the second position, for a vertical connector, it is more convenient to plug the second connector with the first connector while ensuring that the second connector is not easily loosened.

[0056] See also Figure 1 , Figure 3 and Figure 4 The connector 1 and the second connector (circuit board 2) are also locked by a second locking structure 7.

[0057] As configured above, the circuit board 2 is locked by the first locking structure 4 and the second locking structure 7, thereby forming a double locking. Therefore, the second connector (circuit board 2) is less likely to come loose.

[0058] The structure of the second locking structure 7 is not limited, as long as it can achieve the above-mentioned function. The following describes the relevant structure of the second locking structure 7 of the present application in conjunction with the accompanying drawings.

[0059] See also Figure 4 and Figure 3 Combined with Figure 1 , the first connector 1 includes a locking member 12, and the locking member 12 is arranged on the connector body 13. The locking member 12 is provided with a second locking portion 1211. Of course, in some embodiments, the first connector may not include a locking member, but is provided with the second locking portion 1211. The second locking structure 7 includes the second locking portion 1211 and the second matching portion 22. The second locking portion 1211 and the first locking portion 31 lock the second connector in a perpendicular direction. Correspondingly, the second connector (circuit board 2) includes a second matching portion 22, and the first matching portion 21 and the second matching portion 22 lock the first connector 1 in a perpendicular direction. The perpendicular direction is achieved by means of Figure 2 and Figure 3 To understand, Figure 2 and Figure 3 It shows that the first locking portion 31 and the first matching portion 21 are locked in the vertical direction (the direction indicated by the arrow R1), and the second locking portion 1211 and the second matching portion 22 are interlocked in the direction perpendicular to the plane where the second connector (circuit board 2) is located (that is, the direction perpendicular to the direction indicated by the arrow R1) to lock the second connector (circuit board 2) and the connector 1.

[0060] As configured above, since the second locking structure 7 (the second locking portion 1211 and the second matching portion 22) locks the second connector in a direction perpendicular to the first locking structure 4 (the first locking portion 31 and the first matching portion 21), the second connector (circuit board 2) is less likely to loosen. For example, in the illustrated embodiment, the first locking structure 4 locks the second connector (circuit board 2) along the direction of inserting the second connector (circuit board 2), and the second locking structure 7 locks the second connector (circuit board 2) in a direction perpendicular to the electrical insertion direction, thereby locking the circuit board 2 from two different directions, making it less likely for the circuit board 2 to loosen.

[0061] See also Figure 4 and Figure 3 Combined with Figure 1 , the second locking portion 1211 is a hook, and the second matching portion 22 is a notch provided on the side of the second connector (circuit board 2). Of course, in other embodiments, the second locking portion 1211 may be a notch, and the second matching portion may be a hook.

[0062] As described above, one of the second matching portion 22 and the second locking portion 1211 is a notch, and the other of the second matching portion 22 and the second locking portion 1211 is a hook, so that the second locking structure 7 formed by the second locking portion 1211 and the second matching portion 22 can lock the second connector in a direction perpendicular to the insertion direction of the second connector (circuit board 2).

[0063] See also Figure 1 and Figure 3 In some embodiments, when the second mating portion 22 is a notch, the second mating portion 22 and the first mating portion 21 have a common side wall 211, so that the first mating portion 21 and the second mating portion 22 form a stepped shape, which is more conducive to the first locking structure 4 and the second locking structure 7 to lock the first connector from a perpendicular direction, and the second connector (circuit board 2) is less likely to loosen.

[0064] See also Figure 1 Combined with Figure 4 , the locking member 12 includes an elastic arm 121, and the second locking portion 1211 is disposed at the end of the elastic arm 121. In some embodiments, the locking member 12 includes an elastic arm 121 and a mounting portion 122, and the mounting portion 122 is disposed on the connector body 13 of the connector 1, and the connector body 13 is mounted with the conductive terminal 11. Of course, the locking member 12 is not limited to the structure of the mounting portion 122 and the elastic arm 121, as long as it has the elastic arm 121.

[0065] As configured above, since the second locking portion 1211 is disposed at the end of the elastic arm 121 , during the process of inserting the circuit board 2 , the elastic arm 121 utilizes its elasticity to facilitate the second locking portion 1211 to be fastened with the second matching portion 22 .

[0066] In some embodiments, the locking member 12 further includes a mounting portion 122, and the mounting portion 122 forms a U-shape with the elastic arm 121. The structure of the mounting portion 122 is not limited, as long as it can form a U-shape with the elastic arm 121. In the embodiment of the present application, the mounting portion 122 includes a vertical portion 1221 and a connecting portion 1222, and the elastic arm 121, the vertical portion 1221 and the connecting portion 1222 form a U-shape.
