Description

Technical Field

[0002] Connectors are electronic components used in electronic circuits to connect two circuit units, allowing the transmission of electrical signals or power between the circuit units. The contact is the core component of the connector, which is the core part of the connector that realizes the electrical connection function. It refers to the conductive part of the component that cooperates with the corresponding conductive part to form an electrical path. The contact consists of pins and sockets, and circuit connection is realized through mating. It is widely used in automotive electronics, communication equipment and other fields.

[0003] There are many types of connectors. In daily life, circular connectors are widely used. However, in the process of connecting the pins and sockets of the contacts, traditional contact connections often use plug-in connections. The stability of the contact connection is ensured by the friction between the pins and sockets. Although this plug-in and plug-out contact connection method is relatively fast, external vibrations can affect the connection between the contacts, causing the contact connection to loosen. To avoid this, workers will install bolts at the connection of the contacts for limiting. However, adding external components will affect the installation efficiency of the contacts, making it impossible for the contacts to achieve the effect of quick installation.

[0004] Therefore, we provide a metal connector with quick-release and stable contacts. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A quick-release and stable metal connector with contacts, such as... Figures 1-5 As shown, it includes a support connecting cylinder 1, a pin fixing cylinder 2 installed at one end of the support connecting cylinder 1, a pin 3 inside the pin fixing cylinder 2, a plurality of snap-fit ​​grooves 4 on the outer surface of the pin fixing cylinder 2, a socket fixing cylinder 6 outside the snap-fit ​​grooves 4, a socket cylinder 9 installed inside the socket fixing cylinder 6, and a plurality of elastic locking blocks 8 outside the socket cylinder 9.

[0025] The pin fixing cylinder 2 is inserted into the inside of the socket fixing cylinder 6, and several snap-fit ​​grooves 4 are distributed equidistantly in a circle. The elastic snap-fit ​​block 8 is fixedly connected to the inner wall of the socket fixing cylinder 6.

[0026] The elastic block 8 is V-shaped, and the joint of the elastic block 8 is chamfered. The joint of the elastic block 8 is engaged inside the locking groove 4.

[0027] The insert 9 has an insertion hole on its face end. The pin 3 is inserted into the insertion hole on the insert 9. The insert 9 is inserted into the inside of the pin fixing cylinder 2. The outer surface of the insert 9 is tightly fitted to the inner wall of the pin fixing cylinder 2.

[0028] In traditional connector usage, the pins 3 and sockets 9 of the contact are often quickly installed and removed by inserting and pulling. Here, the same insertion method is used to achieve quick installation. After the contact is installed, to further ensure the stability of the connection between the pins 3 and sockets 9, a locking groove 4 is formed on the outer surface of the pin retaining sleeve 2, and an elastic locking block 8 is set inside the socket retaining sleeve 6. During the connection process between the pins 3 and sockets 9, the pin retaining sleeve 2 is inserted into the socket retaining sleeve 6. During this process, the face of the pin retaining sleeve 2 contacts the elastic locking block 8 inside the socket retaining sleeve 6. Because the elastic locking block 8 has a certain elasticity, when the pin retaining sleeve 2 presses against the connection point of the elastic locking block 8, the connection point of the elastic locking block 8 will contract inward. When the pins 3 and sockets 9 are fully connected, the locking groove 4 and the elastic locking block 8 will correspond. At this time, the elastic locking block 8 is no longer compressed and, due to its inherent characteristics, will return to its original shape. The connection point is snapped into the inside of the snap-fit ​​groove 4. The position of the pin fixing cylinder 2 is limited by the connection between the elastic snap block 8 and the snap-fit ​​groove 4. Based on the characteristics of the elastic snap block 8 itself, even if there is external vibration, the elastic snap block 8 will not shake back and forth, further ensuring the stability of the connection between the elastic snap block 8 and the snap-fit ​​groove 4. When removing the pin 3 and the cylinder 9, simply pull the pin fixing cylinder 2 outward to complete the disassembly. By setting up the pin 3 and the cylinder 9, which can be quickly installed and removed with one insertion and one pull, and cooperating with the snap-fit ​​fixation of the elastic snap block 8 and the snap-fit ​​groove 4, the pin 3 and the cylinder 9 on the contact can be fixed at the same time as being inserted. There is no need to fix the pin 3 and the cylinder 9 after the connection through external components, which further improves the installation efficiency of the pin 3 and the cylinder 9 and makes the contact achieve the effect of quick installation. Secondly, it can ensure the stability of the contact after connection while connecting the contact, and avoid the contact connection from loosening due to external vibration and other factors, further ensuring the stability of the contact after installation.

[0029] like Figures 1-5 As shown, a positioning groove 201 is provided at one end of the pin fixing cylinder 2. A positioning block 901 is inserted into the positioning groove 201. The positioning block 901 is fixedly connected to the outer surface of the insert cylinder 9. Flexible barbs are installed on the inner wall of the positioning groove 201. Flexible barbs are also installed on the outer surface of the positioning block 901. The flexible barbs inside the positioning groove 201 engage with the flexible barbs on the outer surface of the positioning block 901.

[0030] When the pin 3 is connected to the insert sleeve 9, to ensure the accuracy of the docking position of the pin 3 and the insert sleeve 9, the pin 3 and the insert sleeve 9 must be in a precise position before insertion. A positioning groove 201 is made on the face of the pin fixing sleeve 2, and a positioning block 901 is installed on the outer surface of the insert sleeve 9. When installing the pin 3 and the insert sleeve 9, simply align and insert the positioning groove 201 and the positioning block 901 to complete the precise installation of the pin 3 and the insert sleeve 9. After the positioning groove 201 and the positioning block 901 are docked, to further ensure the stability of the connection between the pin 3 and the insert sleeve 9, a positioning... The connection between the positioning groove 201 and the positioning block 901 is provided with barbs for engagement. When the positioning block 901 is inserted into the positioning groove 201, the barbs are flexible and will not affect the insertion of the positioning block 901 under the pressure of the barbs in the opposite direction. When the positioning block 901 is fully inserted into the positioning groove 201, the barbs on the positioning block 901 and the positioning groove 201 will form an engagement state due to the flexibility of the barbs, which will further increase the friction between the pin 3 and the sleeve 9. This will ensure that the pin 3 and the sleeve 9 are installed quickly and further improve the stability of the pin 3 after connection.

[0031] like Figures 1-5 As shown, several elastic limiting blocks 5 are installed on the face end of the pin fixing cylinder 2, and the several elastic limiting blocks 5 are distributed equidistantly in a circle.

[0032] A tapered limiting connecting cylinder 7 is installed at one end of the insertion hole fixing cylinder 6. The inner diameter of the tapered limiting connecting cylinder 7 decreases outward from the connection between the insertion hole fixing cylinder 6 and the tapered limiting connecting cylinder 7. The front end of the elastic limiting block 5 is in contact with the inner wall of the insertion hole fixing cylinder 6 and the tapered limiting connecting cylinder 7.

[0033] After the pin 3 of the contact element is connected to the insert 9, in order to further ensure the stability of the connection between the pin 3 and the insert 9, several elastic limiting blocks 5 are set on the face end of the pin fixing cylinder 2. During the insertion process of the pin 3 and the insert 9, the elastic limiting blocks 5 move into the conical limiting connecting cylinder 7 along with the pin 3. When the front end of the elastic limiting block 5 enters the conical limiting connecting cylinder 7, under the compression of the inner wall of the conical limiting connecting cylinder 7, several elastic limiting blocks 5 will be pressed inward at the same time. The elastic limiting blocks 5 and the conical limiting connecting cylinder 7 form a structure similar to a tenon and mortise connection, which further ensures the stability of the connection process between the pin 3 and the insert 9.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
