Description

Technical Field

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

[0002] Connectors are used to connect devices to achieve functions such as data transmission and power supply, such as USB connectors and HDMI connectors.

[0003] At present, traditional connectors on the market are loose in insertion, which affects the connection between connectors. In addition, in order to effectively improve the EMI shielding effect, the existing connectors have added tinplate to the terminal of the connecting machine body. The current tinplate generally uses two upper and lower shells to wrap the terminal, and then the operator welds the upper and lower shells in turn. This practice not only has low production efficiency and high cost, but also the quality of welding cannot be guaranteed. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned defects in the prior art and provide a stable connector. The tinplate of the utility model adopts riveting, which reduces the overall production cost and improves the production efficiency. The elastic spring-pressing parts are arranged on the connector body to make the plugging and unplugging of the connector bracket more stable and not easy to loosen.

[0005] To achieve the above object, the utility model provides a stable connector, comprising:

[0006] A connector body, the connector body comprising a PCB board, a spring-pressing member, a connector head and a connecting terminal sleeved in the connector head, the connecting terminal being connected to one end of the PCB board, the other end of the PCB board away from the connecting terminal being connected to a wire, the spring-pressing member being provided with two reversed top-connecting portions arranged opposite to each other, the reversed top-connecting portions being provided on both sides of the connecting terminal, and the extended direction lines of the reversed top-connecting portions intersecting with the extended direction lines of the connecting terminal;

[0007] The tinplate is arranged outside the connector body, and the tinplate includes an upper shell and a lower shell. The upper shell and the lower shell are both provided with riveting columns and riveting holes, and the riveting fixation of the upper shell and the lower shell is achieved through the cooperation of the riveting columns and the riveting holes.

[0008] An integrally formed insulating shell wraps the connector body and the tinplate.

[0009] Furthermore, the upper shell is provided with a first positioning groove and a first positioning protrusion, and the lower shell is provided with a second positioning protrusion matched with the first positioning groove and a second positioning groove matched with the first positioning protrusion. If it can not only position the upper shell and the lower shell before riveting, it is convenient to install, but also improve the stability of the upper shell and the lower shell during riveting, reduce the situation that the riveting failure will not occur due to deviation during force riveting, and further can better increase the closure of the tinplate after riveting, and there will be no leakage, thereby increasing the EMI shielding effect of the tinplate.

[0010] Furthermore, a wire fixing block is provided between the wire and the PCB board, the wire fixing block extends to both sides to form a wire fixing column, and the tinplate is provided with a wire fixing through hole matching the wire fixing column. In this way, the wire fixing block can be positioned and fixed, so that the wire is not easily displaced by external force to affect the connection with the PCB board, thereby ensuring the connectivity between the two, and having good practicality.

[0011] Furthermore, the wire is close to the end surface of the tinplate to form a flat structure, and the tail of the tinplate is provided with a clamping part, and the flat structure is clamped on the clamping part. The clamping part can be used to fix the wire for a second time, so as to avoid the wire being disconnected from the PCB when subjected to external force, which affects the normal use of the connecting machine.

[0012] Furthermore, the spring-pressing member further comprises a fixing portion, a first bending portion and a second bending portion, a reinforcement portion is formed between the first bending portion and the second bending portion, the reverse folded top connection portion faces the connection terminal, and the first bending portion, the reinforcement portion and the second bending portion form a "V" structure as a whole. The first bending portion and the second bending portion can enhance the elasticity of the spring-pressing member, and the reinforcement portion can ensure the structural rigidity of the spring-pressing member, making it difficult to break.

[0013] Furthermore, the reinforcement part is a reinforcing rib formed by the spring-pressed part protruding outward in a direction away from the connection terminal. The hollow reinforcing rib can improve the bending and compression resistance of the spring-pressed part, maintain the elastic performance of the spring-pressed part, and cooperate with the connector to better fix the connector inserted into the connector and prevent it from falling off.

[0014] Furthermore, the connector body further comprises a rubber core, the connecting terminal is arranged on the rubber core, and the fixing portion is fixedly connected to the rubber core. The setting of the rubber core makes it easier to fix the connecting terminal, and the assembly is more convenient and quick.

[0015] Furthermore, the rubber core is provided with a first clamping groove, and the inner wall of the connector is provided with a first concave clamping block matching the first clamping groove. The clamping method can facilitate the connection between the connector and the rubber core and facilitate assembly.

[0016] Furthermore, the connector also includes an inner connector, the rubber core is provided with a first positioning groove and a second clamping block, the inner connector is provided with a first positioning protrusion matched with the first positioning groove and a second clamping groove matched with the second clamping block, the inner connector is provided with a terminal positioning through hole for positioning the connection terminal, and the two side wings of the inner connector are provided with a first through hole for passing the elastic member, and the elastic member can pass through the first through hole and abut against the inner wall of the connector. The inner connector can be provided to space the connection terminals so that the position restrictions of the connection terminals will not contact each other, thereby ensuring the connection stability of the connector bracket.

[0017] Furthermore, a lead fixing structure is provided at the tail of the insulating housing, so as to fix and protect the wire for the third time and strengthen the fixation of the wire.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] 1. The riveting and fixing of tinplate can be achieved by setting the riveting columns and riveting holes, which can replace the existing welding fixing method, effectively improve the production efficiency of the connector, simplify the production process, and reduce the production cost.

[0020] 2. Furthermore, by setting the first positioning groove, the first positioning protrusion, the second positioning groove and the second positioning protrusion, not only can the upper shell and the lower shell be positioned before riveting, but also the stability of the upper shell and the lower shell can be improved during riveting, and the situation that the riveting failure is caused by the displacement during the force riveting is reduced. Furthermore, the closure of the tinplate after riveting can be better increased, and there will be no leakage, thereby increasing the EMI shielding effect of the tinplate.

[0037] A connector body 1, the connector body 1 includes a PCB board 11, a spring-pressed member 12, a connector 13 and a connecting terminal 14 sleeved in the connector 13, the connecting terminal 14 is connected to one end of the PCB board 11, and the other end of the PCB board 11 away from the connecting terminal 14 is connected to a wire 15. In this embodiment, in order to more stably fix the wire 15, a wire fixing block 151 is further provided between the wire 15 and the PCB board 11, and the wire fixing block 151 extends to both sides to form a wire fixing column 152, and the tinplate 2 is provided with a wire fixing through hole 21 matching the wire fixing column 152, and the wire fixing through hole 21 is assembled by semi-through grooves respectively arranged at corresponding positions of the upper shell 22 and the lower shell 23; in particular, the wire 15 forms a flat structure 153 close to the end face of the tinplate 2, and the tail of the tinplate 2 is provided with a clamping portion 24, and the flat structure 153 is clamped on the clamping portion 24.

[0038] In this embodiment, Figure 4 The elastic member 12 includes a fixing portion 121, a first bending portion 122, a second bending portion 123 and two inverted top connecting portions 124, the inverted top connecting portion 124 faces the connecting terminal 14, the two inverted top connecting portions 124 are arranged on both sides of the connecting terminal 14, and the extended direction line of the inverted top connecting portion 124 intersects with the extended direction line of the connecting terminal 14 on both sides of the connecting terminal 14, and a reinforcing portion 125 is formed between the first bending portion 122 and the second bending portion 123, and the reinforcing portion 125 is a reinforcing rib formed by the elastic member 12 protruding outward in a direction away from the connecting terminal 14;

[0039] In this embodiment, if Figure 5As shown, the connector body 1 also includes a rubber core 3, the connecting terminal 14 is arranged on the rubber core 3, the fixing parts 121 of the two elastic pressure members 12 are fixed to the rubber core 3, the rubber core 3 is provided with a first clamping groove 31, the inner wall of the connecting head 13 is provided with a concave first clamping block 131 matching the first clamping groove 31, the connecting head 13 is clamped with the rubber core 3 through the first clamping groove 31 and the first clamping block 131. In this embodiment, as Figure 3 and Figure 6 The connector 13 further comprises an inner connector 16, which is snap-fitted with the rubber core 3.
