Description

Technical Field

[0001] The present application relates to the field of connectors, and particularly to a connector socket and a connector. Background Art

[0002] In fields such as electronic devices, communication systems, automotive wiring harnesses, and power and signal transmission, as a key component, the stability of the performance and the flexibility of the installation of the connector socket are crucial for the reliable operation of the overall system. Traditional connector sockets often have a relatively single design, mainly adapted to specific types of welding methods (such as only supporting vertical welding or horizontal welding) and connector types, which to a certain extent limits their wide application in different application scenarios.

[0003] Specifically, the installation method of traditional connector sockets on the PCB (printed circuit board) is relatively fixed, usually only able to meet a single welding requirement (such as vertical SMT or horizontal DIP), and cannot flexibly adapt to the diverse needs of different customers or products. In addition, with the continuous miniaturization and integration of electronic products, higher requirements are also put forward for aspects such as the installation space, welding efficiency, and plugging and unplugging reliability of the connector socket.

[0004] In the process of plugging and unplugging and mating of connectors, how to ensure the stable connection and smooth plugging and unplugging between the male connector and the female socket of the connector is another technical problem to be solved. Traditional connector sockets often lack effective guiding and anti-disconnection mechanisms, and are prone to loosening or misplugging under vibration or external force, thus affecting the stability and reliability of signal or power transmission. Summary of the Utility Model

[0005] The purpose of the present application is to provide a connector socket with flexible installation and reliable plugging and unplugging.

[0006] Another purpose of the present application is to provide a connector with simple operation, compact structure, reliable locking and strong compatibility.

[0007] To achieve the above purposes, the present application provides the following technical solutions:

[0008] A connector socket includes a socket body. Holding pieces are respectively arranged on both sides of the socket body. The socket body can be vertically welded on the PCB board through the first welding part of the holding piece or the socket body can be horizontally welded on the PCB board through the second welding part of the holding piece. A buckling position is arranged on the upper surface of the socket body. The buckling position is buckled with the unlocking part of the male connector. A first inclined surface is arranged on the front side of the buckling position, and a second inclined surface is arranged on the rear side of the buckling position. The first inclined surface is used to guide the unlocking part of the male connector, and the second inclined surface is used to improve the anti-disconnection strength between the unlocking part of the male connector and the buckling position.

[0009] The beneficial effects of this embodiment are as follows:

[0010] (1) In this connector socket, holding pieces are designed on both sides of the socket body, and a first welding part and a second welding part are respectively provided. This innovative design enables the socket to flexibly adapt to different installation requirements. It can be vertically welded to the PCB board through the first welding part or horizontally welded to the PCB board through the second welding part. This diverse installation method greatly improves the versatility and flexibility of the product and meets the installation requirements in different application scenarios.

[0011] (2) The buckle position on the upper surface of the socket body of this application is ingeniously designed. The first inclined surface on the front side provides a smooth guiding function for the unlocking part of the male connector of the connector, enabling the male head to be easily and accurately inserted into the socket. The second inclined surface on the rear side enhances the anti - detachment strength between the male head and the buckle position, effectively preventing the connector from accidentally falling off under vibration or external force. This design not only improves the convenience of plugging and unplugging but also ensures the stability and reliability of the connection.

[0012] In one of the embodiments, a guiding groove is provided on the upper surface of the socket body.

[0013] In one of the embodiments, the socket body has a slot, and a fool - proof groove is provided on the upper side of the slot.

[0014] In one of the embodiments, a limiting block extends along the opposite direction of the slot at the lower part of the front side surface of the socket body.

[0015] In one of the embodiments, the length of the limiting block is 1.0 mm - 2.5 mm.

[0016] In one of the embodiments, the length of the limiting block is 1.8 mm.

[0017] In one of the embodiments, a first supporting part is provided at the bottom of the limiting block, and a second supporting part extends downward at the rear side of the bottom of the socket body.

[0018] A connector, the connector includes a connector socket, the connector further includes a connector male head. The connector male head includes a male head body. On the upper surface of the unlocking part of the male head body, a pressing part is formed upward near the front end. On the lower surface of the unlocking part of the male head body, a supporting part extends downward. The upper end of the supporting part is connected to the unlocking part, and the upper and lower ends of the supporting part are connected to the upper surface of the male head body. At the rear end of the unlocking part of the male head body, a locking part extends downward. When the male head body is inserted into the slot of the socket body, it is locked through the cooperation of the locking part and the buckle position. When unlocking, press the pressing part of the unlocking part to make the locking part leave the buckle position to achieve unlocking.

[0019] The beneficial effects of the present application are as follows: In the design of the male connector, a pressing part is specifically arranged at the front end of the upper surface of the unlocking part, so that when the user needs to unlock, only by simply pressing the pressing part, the locking part can be disengaged from the buckling position of the socket body, realizing a quick and convenient unlocking operation. This design greatly improves the user experience and reduces the operation difficulty and complexity.

[0020] In one embodiment, a third inclined surface is provided at the rear side of the locking part, and a fourth inclined surface is provided below the front side of the locking part. Description of the Drawings

[0036] The terms used in the implementation mode part of this application are only used to explain the specific embodiments of this application, rather than aiming to limit this application. The implementation mode of the embodiments of this application will be described in detail below with reference to the drawings.

[0037] As Figure 1 shown, a connector includes a connector socket 1 and a connector plug 2. The connector plug 2 is inserted into the connector socket 1 to achieve electrical performance connection.

[0038] Embodiment 1

[0039] As Figure 2 shown, when the connector socket 1 is horizontally installed on the PCB board 3.

[0040] As Figure 4 Figure 5 And Figure 6 shown, a connector socket 1 includes a socket body 11. Holding piece mounting grooves 12 are respectively arranged on both sides of the socket body 11. Holding pieces 13 are respectively installed in the holding piece mounting grooves 12, and the installation method is to insert them into the holding piece mounting grooves 12 from top to bottom. The socket body 11 can be horizontally welded on the PCB board 3 through the second welding part 122 of the holding piece 13. A buckling position 14 is arranged on the upper surface of the socket body 11. The buckling position 14 is buckled with the unlocking part 21 of the connector plug 2. First inclined surface 141: Located at the front side of the buckling position 14, it is inclined backward relative to the front end of the connector socket 1 body, and is used to guide the unlocking part 21 of the connector plug 2. Second inclined surface 142: Located at the rear side of the buckling position 14, opposite to the first inclined surface 141, it is inclined forward relative to the rear end of the connector socket 1 body, and is used to improve the anti-disengagement strength between the unlocking part 21 of the connector plug 2 and the buckling position 14.

[0041] As Figure 3 shown, when the connector socket 1 is vertically installed on the PCB board 3. The socket body 11 can be vertically welded on the PCB board 3 through the first welding part 121 of the holding piece 13.

[0042] As Figure 4As shown, in one embodiment, a guiding groove 123 is provided on the upper surface of the socket body 11 for guiding in cooperation with the unlocking portion 21 of the male connector. When the male connector is inserted into the slot 124 of the socket body 11, its unlocking portion 21 will be guided in the guiding groove 123 to achieve the cooperation between the unlocking portion 21 and the buckling position 14. The guiding groove 123 provided on the upper surface of the socket body 11 brings significant benefits. The design of the guiding groove 123 aims to solve the technical problem of inaccurate guiding that may occur during the connection process between the male connector and the socket body 11. The guiding groove 123 provides a clear insertion path for the unlocking portion 21 of the male connector, ensuring that the connector can accurately align with the slot 124 of the socket body 11 during insertion, and reducing the risk of connection failure or damage caused by deviation in the insertion direction.

[0043] As Figure 4 shown, in one embodiment, the socket body 11 has a slot 124, and an anti-fooling groove 125 is provided on the upper side of the slot 124. The anti-fooling groove 125 matches the corresponding part of the male connector and can be smoothly docked only when inserted correctly. This design effectively prevents the user from inserting the connector in the reverse direction or in the wrong position due to negligence or misoperation, thereby avoiding problems such as short circuits and equipment damage caused by reverse insertion or misinsertion.

[0044] As Figure 4 shown, in one embodiment, a lengthened limiting block 126 extends along the reverse direction of the slot 124 at the lower part of the front side of the socket body 11. This further enhances this stability and reliability. The main function of the lengthened limiting block 126 is not only to simply increase the stroke, but more importantly, it ensures that the wire-end terminal has enough length to form a longer contact area with the female socket terminal.

[0045] The design of the lengthened limiting block 126 expands the space of the female socket connector in the direction of the slot 124. This means that when the male connector is inserted into the female socket connector, the mating insertion stroke between the two is correspondingly increased, that is, the overall length of the male connector can be made longer, and the terminals inside can also be made longer. The longer mating insertion stroke provides more space for the terminals of the male connector to contact the female socket terminals, thus ensuring that the terminals have enough length to achieve sufficient contact.

[0046] As Figure 5 shown, in one embodiment, the length H of the limiting block 126 is 1.0 mm to 2.5 mm.

[0047] As Figure 5 shown, in one embodiment, the length H of the limiting block 126 is 1.8 mm.

[0048] As Figure 5As shown, if the length H of the stopper 126 is less than 1.0 mm, the contact length between the terminals of the male connector and the female connector may be shortened due to the insufficient length of the stopper 126, thereby reducing the contact area. The reduction in contact area may increase contact resistance and reduce signal transmission quality.

[0049] If the length H of the limiting block 126 is greater than 2.5 mm, manufacturing a longer limiting block 126 may require more material and processing costs, thereby increasing the manufacturing cost of the connector.

[0050] If the length H of the stopper 126 is 1.8 mm, the signal transmission quality, contact resistance and durability of the connector can reach the best state. It can meet the requirements of stability and reliability while maintaining the compactness and cost-effectiveness of the design.

[0051] like Figure 7 As shown, in one embodiment, a first support portion 212 is provided at the bottom of the stop block 126, and a second support portion 213 extends downward from the rear side of the bottom of the socket body 11. Due to the presence of the first support portion 212 and the second support portion 213, the wire end terminal can enter the female connector more smoothly during the insertion process, reducing the problem of poor contact or insufficient contact force caused by shaking. This helps to improve the stability and reliability of signal transmission.

[0052] like Figure 1 As shown, a connector includes a connector socket 1, and the connector also includes a connector male head 2. The connector male head 2 includes a male head body, and the upper surface of the unlocking portion 21 of the male head body is close to the front end to form a pressing portion 211 upward, and the lower surface of the unlocking portion 21 of the male head body extends downward to form a supporting portion 212, the upper end of the supporting portion 212 is connected to the unlocking portion 21, and the upper and lower ends of the supporting portion 212 are connected to the upper surface of the male head body. A locking portion 213 extends downward from the rear end of the unlocking portion 21 of the male head body. When the male head body is inserted into the slot 124 of the socket body 11, the locking portion 213 and the buckle position 14 cooperate with each other to lock it. When unlocking, the pressing portion 211 of the unlocking portion 21 is pressed to allow the locking portion 213 to leave the buckle position 14 to achieve unlocking.

[0053] The beneficial effects of the present application are as follows: in the design of the connector male head 2, a pressing portion 211 is specially provided at the front end of the upper surface of the unlocking portion 21, so that when the user needs to unlock, he only needs to simply press the pressing portion 211 to disengage the locking portion 213 from the buckle position 14 of the socket body 11, thereby realizing a quick and convenient unlocking operation. This design greatly improves the user experience and reduces the difficulty and complexity of operation.

[0054] like Figure 5 and Figure 6As shown, in one embodiment, the rear side of the latch portion 213 has a third inclined surface 2131, and below the front side of the latch portion 213 there is a fourth inclined surface 2132. The fourth inclined surface 2132 plays a guiding role during the insertion process, helping the latch portion 213 to smoothly enter the corresponding position of the socket body 11. This inclined design helps to reduce the resistance during insertion, making the plugging and unplugging process smoother. The combination of the second inclined surface 142 and the third inclined surface 2131 forms a self-locking mechanism. After the latch portion 213 is completely inserted, these inclined surfaces may cooperate with each other to generate a certain locking force, making the connector more firmly connected together. This design helps to prevent the connector from accidentally falling off when subjected to external forces.
