Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a press-connecting type connector. Background Art

[0002] Connectors are an essential part of electronic devices and are used to achieve signal transmission and power supply between different devices or components. Among them, snap-connect connectors are widely used in various electronic devices due to their fast and convenient connection methods. A specific existing connector is as follows:

[0003] Chinese patent document with publication number CN110571592A discloses a connector assembly for quick locking and unlocking, specifically discloses: including a plug and a socket that are plugged and matched, a first locking plate is arranged on the plug, and a socket locking assembly that is snap-connected with the first locking plate is arranged on the socket. The socket locking assembly includes a support rib supported on the side wall of the socket, and a second locking plate and an unlocking plate that are integrally arranged are connected above the support rib. The second locking plate is located in front of the support rib and corresponds to the first locking plate up and down. The second locking plate is snap-connected with the first locking plate, and the unlocking plate is located behind the support rib.

[0004] As can be seen from the above, the existing connector realizes the locking of the plug and the socket through the snap connection between the first locking plate and the socket locking assembly. And, by pressing down the unlocking plate on the socket, due to the supporting effect of the support rib, as the unlocking plate is pressed down, the second locking plate will deform and spring up, and at this time, pulling the plug outwards can realize the separation of the plug and the socket, achieving the quick locking and unlocking of the plug and the socket. However, only through the cooperation between the first locking plate and the socket locking assembly to realize the locking of the plug and the socket, the locking function is relatively single, resulting in a poor connection effect between the plug and the socket. The plugging and unplugging directions of the plug and the socket are the directions of approaching or separating from each other. However, in some places where the connector is located, the space is relatively narrow. Limited by the space, it is difficult for the plug and the socket to move in the directions of separating and approaching each other. Therefore, a press-connecting type connector is provided to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a press-connecting type connector aiming at the deficiencies of the prior art, so as to solve the technical problems of poor connection effect and easy space limitation of the existing connector.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A push-on card connector includes a female seat and a male seat used in conjunction with the female seat, the female seat is provided with a cavity with an opening facing upward for the male seat to be longitudinally embedded; a card connection structure is provided between the male seat and the female seat to achieve mutual locking; a pressing portion is provided at a position off-center of the male seat, and a groove communicating with the cavity to provide a movable space for the male seat is provided at the bottom of the cavity, so that an external force can overcome the constraint of the card connection structure and press the pressing portion, so that the male seat can be partially embedded in the groove and the male seat can be tilted up as a whole to separate from the female seat.

[0008] Furthermore, the clamping structure includes a clamping portion located at one end of the male seat, and a protrusion located on the inner wall of the cavity for clamping the clamping portion, and a groove (located on a side away from the protrusion, and applying force to the pressing portion of the male seat so that the end of the male seat provided with the clamping portion is tilted and separated from the protrusion.

[0009] Furthermore, an embedding block is provided on one end of the male seat away from the clamping portion, and a receiving groove for embedding the embedding block is provided on the inner side wall of the cavity; the receiving groove is communicated with the groove.

[0010] Furthermore, a pressing protrusion is fixedly provided on the top of the male seat, and the pressing protrusion is placed on a side away from the clamping portion.

[0011] Furthermore, a recess is provided on the top of the female seat to provide a movable space for the pressing protrusion.

[0012] Furthermore, both the male and female sockets are plastic parts.

[0013] Furthermore, a plurality of female terminals are arranged in a separated manner on the side walls at both ends or on a single side wall of the female seat, and the female terminals extend into the cavity; a plurality of male terminals for contacting the female terminals are provided on the male seat, and the number and position of the male terminals correspond to those of the female terminals. Each male terminal is fixed with a transmission line, and the transmission lines are placed on the side of the male seat away from the female seat; the part of the female terminal placed in the cavity is a curved elastic structure.

[0014] Furthermore, the length direction of the transmission line is perpendicular to the direction in which the male socket is embedded in the cavity.

[0015] Furthermore, a placement groove for placing a plurality of transmission lines is provided on the top of the mother seat.

[0016] Furthermore, a bevel is provided on the groove wall away from the accommodating groove.

[0017] Beneficial effects of the utility model:

[0018] 1. When it is necessary to connect the male socket and the female socket, place the male socket at a position longitudinally aligned with the cavity and then press it to press the male socket into the cavity. The clamping portion enters the cavity after passing through the protruding portion so that the clamping portion is stuck between the protruding portion and the inner bottom of the cavity, thus completing the connection between the male socket and the female socket. Compared with the prior art where the connecting block is arranged at the end, the connecting port of the female socket in this application is arranged at the top, and the male socket and the female socket are directly inserted and latched. Whether the female socket is placed horizontally, vertically or obliquely, the male socket can be installed into the cavity along a straight movement track, making the installation operation more convenient.

[0019] 2. Based on the above change in the connection direction, the pin pitch of the male socket and the female socket can be made smaller, achieving a greater pin density, which is beneficial to realizing more power and signal transmissions in a smaller space.

[0020] 3. In the prior art with the horizontal port plugging method, the female socket needs to reserve enough space in height for the male socket to be inserted. Considering the installation structures for pins (terminals) on the upper and lower sides of the male and female sockets, the height of the existing female socket is relatively large. However, in this application, the male socket is inserted from the top of the female socket, and the terminals are installed at both ends of the female socket. Therefore, the height after the connection of the female socket and the male socket is low, saving space.

[0021] 4. After connecting the male socket and the female socket, the male socket has no possibility of detaching from the cavity whether it is along the X-axis, Y-axis or Z-axis of the female socket. During vibration, the male socket will not be shaken out of the cavity either, making the connection between the male socket and the female socket more reliable and ensuring that it can pass the anti-vibration test.

[0022] 5. When it is necessary to separate the male socket and the female socket, apply a force to the pressing portion of the male socket in the direction towards the groove. Under the action of the groove provided at the inner bottom of the cavity, the pressing portion of the male socket moves, causing the end provided with the clamping portion to tilt up, so that the clamping portion disengages from the cavity, and finally the entire male socket can be directly taken out of the cavity, thus completing the separation of the male socket and the female socket. Only by applying force to the pressing portion of the male socket can it be separated from the female socket, making it more convenient for the user to operate when using this connector. Moreover, when using this connector in a relatively narrow space, it is also convenient to insert and remove the male socket. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0032] The following describes a press-and-clamp connector of the present utility model in detail with reference to the accompanying drawings.

[0033] As Figures 1-4As shown, an embodiment of a push-on connector of the utility model includes a male base 2 and a female base 1 used in conjunction therewith, and a cavity 3 for the male base 2 to be embedded is provided on the top of the female base 1, wherein a plurality of female terminals 4 arranged in a separated manner are provided on the side walls at both ends of the female base 1, and a plurality of female terminals 4 arranged in a separated manner can also be provided on a single side wall of the female base 1, and the female terminals 4 extend into the cavity 3. A plurality of male terminals 5 for contacting the female terminals 4 are provided on the male base 2, and the number and position of the male terminals 5 correspond to those of the female terminals 4, and each male terminal 5 is fixedly provided with a transmission line 6, and the transmission line 6 is placed on the side of the male base 2 away from the female base 1. When it is necessary to connect the male socket 2 and the female socket 1, align the male socket 2 with the cavity 3 on the female socket 1, then apply force to the male socket 2 toward the female socket 1, and press the male socket 2 into the cavity 3 so that the female terminal 4 contacts the corresponding male terminal 5; and after the male socket 2 is embedded in the cavity 3 of the female socket 1, the overall height of the connector is reduced (the height is 2cm), thereby saving space. The part of the female terminal 4 placed in the cavity 3 is elastically arranged. When the male socket 2 is completely embedded in the cavity 3, under the action of the elastic part of the female terminal 4, the female terminal 4 can fully contact the male terminal 5. The female terminal 4 can also be arranged on both sides of the female socket 1 in a relative arrangement. After the male socket 2 is pressed into the cavity 3, the female terminals 4 on both sides can also play a certain clamping role to clamp the male socket 2 so that it will not easily escape from the cavity 3; and the female terminals 4 are arranged on the side walls of the female socket 1, so that the pin spacing between the female terminals 4 is small and the density is large, which is conducive to realizing multi-channel power and signal transmission in a small space. In addition, the length direction of the transmission line 6 is perpendicular to the direction in which the male socket 2 is embedded in the cavity 3. This arrangement is to further reduce the overall height of the connector after the male socket 2 is connected to the female socket 1.

[0034] Furthermore, in order to ensure that the male socket 2 and the female socket 1 can be stably connected, a pair of clamping parts 9 are fixedly provided on the side of the male socket 2, and a protrusion for clamping the clamping part 9 is provided on the inner wall of the cavity 3; the male socket 2 and the female socket 1 are both plastic parts. When the two need to be connected, the male socket 2 is placed in a position aligned with the cavity 3 and force is applied to it to press the entire male socket 2 into the cavity 3, and the clamping part 9 enters the cavity 3 after passing through the protrusion 10, so that the clamping part 9 is clamped between the protrusion 10 and the bottom of the cavity 3. With the cooperation of the clamping part 9 and the protrusion 10, the male socket 2 and the female socket 1 are stably connected to prevent the male socket 2 from being separated from the female socket 1 when the connector is used; and the male socket 2 and the female socket 1 are fastened by direct plug-in. Regardless of whether the female socket 1 is placed horizontally, vertically or tilted, the male socket 2 can be installed into the cavity 3 with a straight moving trajectory, making the installation operation more convenient.

[0035] Preferably, the clamping portion 9 is provided on one end of the male seat 2, and an insert 8 is provided on the other end, and a receiving groove 7 for inserting the insert 8 is provided on the inner wall of the cavity 3. Figures 3-4 As shown, when the female seat 1 is placed horizontally, the male seat 2 is placed directly above the female seat 1 to align with the cavity 3 (when the female seat 1 is placed vertically, the male seat 2 is placed beside the female seat 1), and then a force is applied to the male seat 2 toward the female seat 1. Because the male seat 2 and the female seat 1 are both plastic parts, after the clamping portion 9 passes through the protruding portion 10 to enter the cavity 3, the clamping portion 9 is clamped between the protruding portion 10 and the bottom of the cavity 3, and the embedded block 8 is embedded in the accommodating groove 7 at the same time (during the embedding process, the part of the female seat 1 that contacts the embedded block 8 will be deformed, and the deformation provides sufficient space for the embedded block 8 to move. After the embedded block 8 is completely embedded in the accommodating groove 7, the part of the female seat 1 will automatically recover, and the embedded block 8 embedded in the accommodating groove 7 is limited by this part). With the embedded block 8 embedded in the accommodating groove 7 and the protruding portion 10 clamping the clamping portion 9, the male seat 2 and the female seat 1 can be connected more stably.

[0036] The second connection method between the male socket 2 and the female socket 1 is as follows Figures 6-7 As shown, the male socket 2 first places the embedded block 8 into the cavity 3 at a certain angle, and then presses the end of the male socket 2 away from the embedded block 8 to press the entire male socket 2 into the cavity 3, and the clamping portion 9 is clamped between the protrusion 10 and the bottom of the cavity 3, and the embedded block 8 is automatically embedded in the accommodating groove 7, completing the second connection method between the male socket 2 and the female socket 1; under the action of the above two connection methods, the male socket 2 and the female socket 1 can be easily installed when they are in different environments, further improving the convenience of connecting the male socket 2 and the female socket 1.

[0037] In order to separate the male seat 2 and the female seat 1, a groove 12 is provided at the bottom of the cavity 3, and the groove 12 is located on the side away from the protrusion 10, and the receiving groove 7 is connected to the groove 12; when the male seat 2 and the female seat 1 need to be separated, the end of the male seat 2 provided with the insert 8 is pressed to press the insert 8 from the receiving groove 7 into the groove 12, and the end of the male seat 2 provided with the clamping portion 9 will be lifted up (such as Figure 5 As shown), the clamping portion 9 is separated from the cavity 3, and finally, the entire male seat 2 can be directly taken out of the cavity 3, and the male seat 2 and the female seat 1 are separated. A bevel 15 is provided on the groove wall of the groove 12 away from the accommodating groove 7. Under the action of the bevel 15, after the male seat 2 is forced, the insert 8 can be more fully pressed into the groove 12. When the groove 12 is set to a specific size, the activity space of the insert 8 is increased.

[0038] When connecting, the male socket 2 is vertically inserted into the cavity 3 of the female socket 1. When separating, press the male socket 2 to tilt it out of the cavity 3, making it more convenient to use this connector. Moreover, after the male socket 2 is installed in the cavity 3, the surrounding side walls in the cavity 3 abut against the side of the male socket 2. After the male socket 2 is connected to the female socket 1, there is no possibility for the male socket 2 to separate from the cavity 3 whether it is along the X-axis, Y-axis or Z-axis of the female socket 1. Additionally, during vibration, the male socket 2 will not be shaken out of the cavity 3, making the connection between the male socket 2 and the female socket 1 more reliable.

[0039] Preferably, in order to facilitate pressing the male socket 2 to separate it from the cavity 3, a pressing protrusion 11 is fixedly provided at the top of the male socket 2, and the pressing protrusion 11 is located on the side away from the engaging portion 9. A relief groove 13 for providing a moving space for the pressing protrusion 11 is provided at the top of the female socket 1. Apply a force to the pressing protrusion 11 in the direction towards the groove 12 to press the insert block 8 from the accommodation groove 7 into the groove 12, and the end of the male socket 2 with the engaging portion 9 will tilt up. The relief groove 13 provides a space for the pressing protrusion 11 to tilt, preventing the pressing protrusion 11 from being blocked. Under the action of the pressing protrusion 11, the force application point when applying force to the male socket 2 can be more accurate, further improving the efficiency of separating the male socket 2 and the female socket 1. When using this connector in a relatively narrow space, it is also convenient to insert and remove the male socket 2. Additionally, a placement groove 14 for placing a plurality of transmission lines 6 is provided at the top of the female socket 1. When the male socket 2 is connected to the female socket 1, the transmission lines 6 are placed in the placement groove 14 to prevent the female socket 1 from pushing up the transmission lines 6 and bending them, thereby damaging the transmission lines 6, improving the service life of this connector. Moreover, it can also save space and make the overall appearance more beautiful after the male socket 2 is connected to the female socket 1.

[0040] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to have practicality by enhancing the efficiency that has never been achieved in the prior art during use, and becoming a product with extremely high practical value.

[0041] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
