Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a patch connector. Background Technology

[0002] A surface mount electrical connector is a type of connector that is electrically connected to a PCB by soldering. Wires or male terminals can be mounted on the surface mount electrical connector to achieve electrical connection with the PCB.

[0003] Surface mount electrical connectors typically consist of a housing and a conductive clip, which is directly soldered to the PCB board. During use, existing surface mount connectors are prone to wobbling or even detachment at the contact point between the conductive clip and the connector components, leading to poor stability. To address this issue, we propose a new surface mount connector. Utility Model Content

[0004] The purpose of this invention is to provide a surface mount connector to solve the problem mentioned in the background art, where existing surface mount electrical connectors are prone to shaking or even falling off during use, resulting in poor stability of the surface mount connector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a patch connector, comprising a housing, a base plate, and a conductive sheet, wherein the base plate is snapped onto the housing, and a second snap-fit ​​plate and a first snap-fit ​​plate are respectively provided on the housing and the base plate, the first snap-fit ​​plate and the second snap-fit ​​plate are mutually fitted and engaged opposite each other, and a socket slot is evenly provided on the right side of the housing, and a V-shaped guide opening is provided at the inner end of the socket slot, and a snap-fit ​​interface is provided on the housing opposite to the socket slot. The inner end of the card interface is provided with a clearance groove that communicates with it. The inner cavity of the insertion slot and the clearance groove are connected. A conductive clip is snapped into the inside of the card interface. The conductive clip is electrically connected to the PCB board. The conductive clip is provided with a V-shaped guide groove 1 and a V-shaped guide groove 2 in sequence from the insertion end outward. A guide block is provided on the outside of the conductive clip that is inserted into the clearance groove. The base plate is provided with a card interface 2 for inserting the conductive clip at the position corresponding to the card interface 1. A V-shaped guide port 2 is provided on the outside of the card interface 2.

[0006] Preferably, the slots and card interfaces are positioned opposite each other, and the number of slots and card interfaces is equal.

[0007] Preferably, both the first and second buckle plates are provided with inclined surfaces facing away from each other.

[0008] Preferably, the flared openings of both the first V-shaped drainage groove and the second V-shaped drainage groove face one side of the insertion slot, and the V-shaped angle of the first V-shaped drainage groove is greater than the V-shaped angle of the second V-shaped drainage groove.

[0009] Preferably, the height of the guide block is less than the depth of the relief groove, and the guide blocks are arranged symmetrically at the top and bottom.

[0010] Preferably, the housing has slots for inserting conductive sheets, and the conductive sheets are sandwiched between adjacent conductive sheets.

[0011] Preferably, the first buckle plate and the second buckle plate are of equal length.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of surface mount connector, by setting V-shaped guide groove one, V-shaped guide groove two, and guide block on the conductive clip, makes it easier for the conductive clip to engage during the engagement process. After the guide block aligns with the upper and lower positions of the relief groove, the guide block is placed inside the relief groove, which effectively restricts the position of the conductive clip on the housing. After the pin is inserted into the socket slot on the base plate, the pin engages with the locking position of the conductive clip. At this time, the V-angle of V-shaped guide groove one and V-shaped guide groove two is increased, making it easier to insert. Moreover, after insertion, the reset effect of V-shaped guide groove one and V-shaped guide groove two makes the contact between the conductive clip and the pin tighter, further improving the conductivity.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-6 This utility model provides a technical solution: a patch connector, including a housing 1 and a base plate 4. The base plate 4 is snapped onto the housing 1. A second snap-fit ​​plate 11 and a first snap-fit ​​plate 42 are respectively provided on the housing 1 and the base plate 4. The first snap-fit ​​plate 42 and the second snap-fit ​​plate 11 are mutually fitted and snapped together facing each other. Both the first snap-fit ​​plate 42 and the second snap-fit ​​plate 11 have opposing inclined surfaces. The first snap-fit ​​plate 42 and the second snap-fit ​​plate 11 are of equal length. Guide inclined surfaces are provided on the opposing surfaces of the first snap-fit ​​plate 42 and the second snap-fit ​​plate 11. The inclined surfaces facilitate the snap-fit ​​of the base plate 4 onto the housing 1. Through the provision of the first snap-fit ​​plate 42 and the second snap-fit ​​plate 11, the base plate 4 can be quickly and securely connected to the housing 1.

[0023] Please see Figure 3 The housing 1 has evenly spaced insertion slots 41 on its right side. A V-shaped guide 43 is provided at the inner end of each insertion slot 41, which guides the insertion pins. A locking interface 13 is located on the housing 1 opposite to the insertion slots 41. A clearance groove 12 communicates with the inner end of the locking interface 13. The insertion slots 41 and clearance groove 12 are connected. A conductive clip 2 is locked inside the locking interface 13 and electrically connected to the PCB board. The conductive clip 2 securely fixes the conductor in a specific position, preventing loosening or displacement under external force, ensuring the stability and reliability of the electrical connection. It also allows the incoming and outgoing lines to connect to the internal terminals of the equipment, ensuring a normal power supply.

[0024] Furthermore, the conductive clip 2 is provided with a V-shaped guide groove 21 and a V-shaped guide groove 22 sequentially from the insertion end outwards. The flared ends of both the V-shaped guide groove 21 and the V-shaped guide groove 22 face the side of the insertion slot 41, and the V-angle of the V-shaped guide groove 21 is larger than that of the V-shaped guide groove 22. A guide block 23 is provided on the outside of the conductive clip 2, which is inserted into the relief slot 12. The height of the guide block 23 is less than the depth of the relief slot 12, and the guide blocks 23 are arranged symmetrically vertically. A card interface 44 for inserting the conductive clip 2 is provided on the base plate 4 at the position corresponding to the card interface 13. A V-shaped guide opening 45 is provided on the outside of the card interface 44. Initially, the V-angles of V-shaped guide groove 21 and V-shaped guide groove 22 are constant. After the corresponding pins are inserted, the insertion of the pins increases the V-angles of V-shaped guide groove 21 and V-shaped guide groove 22, causing the guide block 23, which is located outside the conductive clip 2 and inserted into the relief groove 12, to engage within the relief groove 12, thereby fixing the position of the conductive clip 2 on the housing 1. The resetting effect of V-shaped guide groove 21 and V-shaped guide groove 22 on the conductive clip 2 ensures a tighter contact between the conductive clip 2 and the pins, further improving conductivity. After the conductive clip 2 is soldered onto the PCB board, power can be continuously transmitted to the connector components, making the connector's operation more stable.

[0025] In this example, the insertion slot 41 and the card interface 44 are positioned opposite each other, and the number of insertion slots 41 and card interfaces 44 is equal. The housing 1 has slots for inserting conductive sheets 3, and the conductive clips 2 are located between adjacent conductive sheets 3.

[0026] Working principle: This type of surface mount connector, when used, is connected via, as follows: Figure 1 and Figure 2 As shown, the housing 1 and the base plate 4 are snapped together. At this time, the first snap-on plate 42 is placed to the left of the second snap-on plate 11. The conductive clip 2 is snapped onto the corresponding snap-on interface 13 on the housing 1. At this time, the snap-on opening of the conductive clip 2 is snapped onto the upper and lower sides of the snap-on interface 13. During the snap-on process, it is easier to snap in through the V-shaped guide groove 21 and the second V-shaped guide groove 22. After the guide block 23 corresponds to the upper and lower positions of the relief groove 12, the guide block 23 is placed inside the relief groove 12. The guide block 23 can effectively restrict the conduction. The position of the electric clip 2 on the housing 1; after the pin is inserted into the insertion slot 41 on the base plate 4, the pin is locked into the slot of the conductive clip 2. At this time, the V-shaped angle of the V-shaped guide groove 1 21 and the V-shaped guide groove 22 is increased, making it easier to insert; after insertion, the reset effect at the V-shaped guide groove 1 21 and the V-shaped guide groove 22 makes the conductive clip 2 contact the pin more tightly, further improving the conductivity; after connection, the conductive clip 2 can be soldered to a specific position on the PCB board.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
