Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a printed circuit board electrical connector. Background Technology

[0002] Printed circuit board (PCB) electrical connectors are connectors that integrate printed circuit boards. Because of the integrated PCB, electrical connectors can achieve more functions and are widely used in existing technologies.

[0003] Printed circuit board (PCB) electrical connectors include plugs and sockets. The plug and socket mate to connect circuits or perform other functions. Meanwhile, electronic components on the PCB can perform functions such as monitoring circuits. In the prior art, the plug and socket of PCB electrical connectors are typically fixed with screws, which presents technical problems such as inconvenient assembly. Furthermore, screws are prone to loosening when operating in vibrating environments.

[0004] Therefore, existing printed circuit board electrical connectors have technical problems such as being prone to loosening and inconvenient assembly. Utility Model Content

[0005] The present invention provides a printed circuit board electrical connector that solves the technical problems of easy loosening and inconvenient assembly of existing printed circuit board electrical connectors.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A printed circuit board electrical connector, including a plug;

[0008] and socket, wherein the plug is inserted into the socket;

[0009] The plug is provided with a pin, the socket is provided with a socket that mates with the pin, and the socket is provided with a guide, the guide extending out of the socket by a length greater than the pin extending out of the plug;

[0010] The socket is provided with a locking device to lock the position of the plug relative to the socket. The locking device is slidably connected to the plug, and the guide is provided with a locking groove that cooperates with the locking device.

[0011] Preferably, the plug is provided with a guide groove, the locking device is slidably connected in the guide groove, and the locking groove is provided with an elastic element that pushes the locking device to engage with the locking groove.

[0012] Preferably, the guide groove is provided with a guide groove, and the locking device is provided with a guide ridge that cooperates with the guide groove.

[0013] Preferably, the guide is provided with an inclined surface that pushes the locking device to move away from the locking groove, overcoming the elastic force of the elastic element, and the locking device is provided with an arc-shaped contact surface that contacts the inclined surface.

[0014] Preferably, there are two sets of locking devices, which are respectively disposed on the upper and lower surfaces of the plug, and each set of locking devices includes two locking devices.

[0015] Preferably, the sliding direction of the locking device is perpendicular to the direction of movement of the plug relative to the socket when the plug and socket are assembled.

[0016] Preferably, the guide ridge and the locking device are an integral structure.

[0017] Preferably, the guide is provided with a groove that mates with the plug, a portion of the plug is located within the groove, and the guide and the socket are an integral structure.

[0018] Preferably, the locking device is further provided with a handle for easy operation to move the locking device away from the locking groove, overcoming the elastic force of the elastic element.

[0019] Preferably, there are two handles, which are located on opposite sides of the plug, and each handle is provided with two locking devices.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] By setting a guide, the plug is guided. During the assembly of the plug and socket, the guide can limit the position of the plug relative to the socket, thereby making the plug have higher displacement accuracy relative to the socket. During the assembly of the plug and socket, the pins and sockets are less likely to be misaligned, thus making the electrical connector easier to assemble.

[0022] By providing a locking groove in the guide and a locking device in the plug, the locking device engages with the locking groove. During assembly, assembly can be completed simply by engaging the locking device with the locking groove. Compared to using screws for locking, the engagement of the locking device with the locking groove makes the connector easier to assemble.

[0023] In addition, because the plug and socket are locked by a locking device and a locking groove, the plug and socket of the connector will not loosen even when working in a vibrating environment, which improves the stability of the connector during operation. Attached Figure Description

[0034] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0035] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0036] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0037] Reference Figures 1 to 5 As shown, a printed circuit board electrical connector includes a plug 1;

[0038] The plug 1 is inserted into the socket 2;

[0039] The plug 1 is provided with a pin 11, the socket 2 is provided with a socket 21 that mates with the pin 11, and the socket 2 is provided with a guide 22, the length of which the guide 22 extends out of the socket 2 is greater than the length of which the pin 11 extends out of the plug 1.

[0040] The socket 2 is provided with a locking device 12 to lock the position of the plug 1 relative to the socket 2. The locking device 12 is slidably connected to the plug 1. The guide 22 is provided with a locking groove 221 that cooperates with the locking device 12.

[0041] Understandably, during the assembly process of plug 1 and socket 2, when the pin 11 is not in contact with the side wall of socket 21, the guide 22 has already cooperated with plug 1. That is, the position of plug 1 relative to socket 2 has been defined by guide 22. At this time, the pin 11 has higher positional accuracy relative to socket 21, so that the pin 11 and socket 21 are not easily misaligned and the pin 11 is not easily damaged during the assembly process.

[0042] Reference Figures 1 to 4 As shown, in some embodiments, the plug 1 is provided with a guide groove 13, the locking device 12 is slidably connected in the guide groove 13, and the locking groove 221 is provided with an elastic member 131 that pushes the locking device 12 to engage with the locking groove 221.

[0043] The locking device 12 slides within the guide groove 13. When the locking device 12 slides to a state where it engages with the locking groove 221, that is, at least a portion of the locking device 12 is located within the locking groove 221, the position of the plug 1 relative to the socket 2 is locked by the locking device 12 and the locking groove 221. Because the locking device 12 slides within the guide groove 13, it will not disengage from the guide groove 13, thereby locking the relative position of the plug 1 and the socket 2.

[0044] In some embodiments, the guide groove 13 is provided with a guide groove, and the locking device 12 is provided with a guide ridge 121 that cooperates with the guide groove.

[0045] In some embodiments, the cross-sectional shape of the guide ridge 121 can be rectangular. Specifically, the relative position of the plug 1 and the socket 2 is defined by the locking device 12 and the locking groove 221. The connection strength between the locking device 12 and the plug 1 determines the connection strength between the plug 1 and the socket 2. Therefore, the locking device 12 should have a high connection strength with the plug 1.

[0046] By setting the guide ridge 121, the guide ridge 121 not only improves the displacement accuracy of the locking device 12, but also improves the connection strength between the locking device 12 and the plug 1, so that the plug 1 can withstand greater force. That is to say, even if the plug 1 is subjected to greater force, the locking device 12 and the plug 1 will not separate due to the higher connection strength of the locking device 12 and the plug 1 under the action of the guide ridge 121, so that the plug 1 will not separate from the socket 2.

[0047] Reference Figures 1 to 4 As shown, in some embodiments, the locking device 12 may be made of a metal material to provide a higher connection strength between the locking device 12 and the plug 1.

[0048] In some embodiments, there may be one or more guide ridges 121. The more guide ridges 121 there are, the stronger the connection between the locking device 12 and the plug 1.

[0049] Understandably, the locking device 12 and the guide groove 13 can be assembled using a heat-fitting method, or the plug 1 can also be a separate structure. Preferably, the locking device 12 and the guide groove 13 are assembled using a heat-fitting method.

[0050] In some embodiments, the elastic element 131 is a spring. One end of the elastic element 131 is fixed to the locking device 12, and the other end of the elastic element 131 is fixed to the side wall of the guide groove 13.

[0051] In some embodiments, one end of the spring is welded to the locking device 12, and the other end of the spring is welded to the side wall of the guide groove 13.

[0052] In some embodiments, both the locking device 12 and the guide groove 13 have protrusions on their sidewalls, and the spring is sleeved on the protrusions. The protrusions guide the spring, making it less prone to bending and extending its service life.

[0053] In some embodiments, the guide 22 is provided with an inclined surface 222 that pushes the locking device 12 to move away from the locking groove 221 against the elastic force of the elastic member 131, and the locking device 12 is provided with an arc-shaped contact surface 122 that contacts the inclined surface 222.

[0054] Understandably, when the inclined surface 222 contacts the arc-shaped contact surface 122, the force exerted by the inclined surface 222 on the arc-shaped contact surface 122 is divided into two components. One component is parallel to the axis of the elastic element 131, so that the component can overcome the force of the elastic element 131 and move the locking device 12 away from the locking groove 221, and the plug 1 and the socket 2 can be assembled normally.

[0055] After the plug 1 and socket 2 are assembled, the locking device 12 is positioned directly opposite the locking groove 221. Under the force of the elastic element 131, the locking device 12 enters the locking groove 221, thereby locking the relative positions of the plug 1 and socket 2.

[0056] In some embodiments, there are two sets of locking devices 12, which are respectively disposed on the upper and lower surfaces of the plug 1, and each set of locking devices 12 includes two locking devices 12. That is, a total of four locking devices 12 are disposed on the plug 1.

[0057] In some embodiments, the sliding direction of the locking device 12 is perpendicular to the movement direction of the plug 1 relative to the socket 2 when the plug 1 and the socket 2 are assembled.

[0058] In some embodiments, the guide ridge 121 and the locking device 12 are an integral structure.

[0059] In some embodiments, the guide 22 is provided with a groove 223 that mates with the plug 1, a portion of the plug 1 is located within the groove 223, and the guide 22 and the socket 2 are integrally formed. There are two guides 22, located on the left and right sides of the plug 1 respectively. The left and right sides of the plug 1 refer to the left and right positions relative to the direction of movement of the plug 1 when the plug 1 and the socket 2 are assembled.

[0060] Reference Figure 5 As shown, in practice, the locking device 12 described in the above scheme has four locking devices. In application environments where the plug 1 and socket 2 need to be frequently disconnected and reconnected, the four locking devices 12 make it inconvenient to disconnect the plug 1 and socket 2. It is necessary to operate four locking devices 12 to disconnect the connector. Therefore, in some embodiments, the locking device 12 is also provided with a handle 3 to facilitate the operation of the locking device 12 so that the locking device 12 overcomes the elastic force of the elastic member 131 and moves away from the locking groove 221.

[0061] In some embodiments, there are two handles 3, which are respectively located on both sides of the plug 1, and each handle 3 is provided with two locking devices 12. The two locking devices 12 provided on the handle 3 can be integrated with the handle 3.

[0062] Two handles 3 are located on the left and right sides of the plug 1, respectively, and the guide 22 is located between the handles 3 and the plug 1.

[0063] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0064] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0065] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
