[0002] Connector terminals are an accessory product used to achieve electrical connections and are widely used in industrial automation and electronic and electrical equipment. Connector terminals are usually divided into male terminals and female terminals. Male terminals are generally protruding connectors, while female terminals are recessed connectors. They play a vital role in circuit connections and can provide stable and reliable electrical connections to ensure the safety and stability of the circuit system.
[0003] However, current connector terminals are all connected by direct plugging. However, this direct plugging method has poor stability and is prone to loosening or even falling off when the line is accidentally dragged. At the same time, it is difficult to determine the effect of the direct plugging method and whether it is plugged in properly, which reduces the use effect.
[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1-6 The utility model provides a technical solution: comprising a female terminal housing 1 and a male terminal housing 2, a data line 3 is connected to one side of the male terminal housing 2, mounting grooves are provided on both sides of the male terminal housing 2, and a fixing seat 4 is connected to one side of the mounting groove, and a limiting unit 5 is provided on the top of the fixing seat 4. Figure 5 It can be seen that one end of the limiting unit 5 extends through 2, wherein the inner side of the female terminal housing 1 corresponds to the limiting unit 5 and is provided with a limiting groove that matches one end of the limiting unit 5, which is used to engage with the limiting unit 5 and limit the position. One end of the fixing seat 4 is sleeved with an extrusion spring 6, and the top of the extrusion spring 6 extends into the limiting unit 5. A reset spring 7 is connected in the mounting groove, and the limiting unit 5 is slidably connected to the reset spring 7. A support spring 8 is connected to one side of the reset spring 7 to support the reset spring 7 to ensure the reset effect of the reset spring 7. The other end of the support spring 8 is fixedly arranged on one side of the mounting groove. Figure 5 It can be seen that a limiting ring is provided at one end of the support spring 8 to ensure the stable position of the support spring 8. Fitting grooves are provided on both sides of the inner wall of the female terminal housing 1, and a guide rod 9 is connected between the inner sides of the fitting grooves. An extrusion unit 10 is slidably provided at one end of the guide rod 9, and a traction spring 11 is sleeved and connected at the other end of the guide rod 9. One end of the traction spring 11 is connected to the extrusion unit 10. A mounting piece 14 is connected to both sides of the female terminal housing 1.
[0023] Reference Figure 1-3As shown, a reinforcement end 21 is connected to one side of the male terminal housing 2 to ensure the connection effect between the data line 3 and the male terminal housing 2. One end of the data line 3 passes through the reinforcement end 21 and extends into the male terminal housing 2, and is connected to a male terminal 31. A female terminal connected to the male terminal 31 is connected to the female terminal housing 1. Since it is an existing mature technology, it is not described in detail in the specification.
[0024] Reference Figure 6 As shown, the limiting unit 5 includes a connecting seat 51, a limiting end 52 is provided at the top of the connecting seat 51, and sliding ends 53 are provided on both sides of the connecting seat 51. The limiting ends are arranged as inclined surfaces. When the male terminal housing 2 is plugged in, the female terminal housing 1 can squeeze the limiting unit 5 into the installation groove. A sliding groove is provided at the top of one side of the reset spring piece 7 corresponding to the sliding end 53. When the reset spring piece 7 presses down the connecting seat 51, displacement and sliding are allowed to occur between the reset spring piece 7 and the sliding end 53.
[0025] Reference Figure 4 As shown, the extrusion unit 10 includes an extrusion end 101 that is slidably connected to the guide rod 9, and a connecting end 102 is connected to one side of the extrusion end 101, and a stop head 103 is connected to the other end of the connecting end 102. One side of the stop head 103 is engaged with the male terminal housing 2, and a slope is provided on one side of the extrusion end 101, wherein a slope is also provided on one side of the engaging groove. When the male terminal housing 2 is inserted into the female terminal housing 1, it will resist the stop head 103. As the male terminal housing 2 is inserted, the extrusion end 101 will be driven to slide along the guide rod 9 through the connecting end 102. When the slope on one side of the extrusion end 101 is in contact with the slope on one side of the engaging groove, the continuous displacement will cause the extrusion end 101 to move downward, thereby extruding the male terminal housing 2 for fixing. The hollow space opened in the extrusion end 101 corresponding to the guide rod 9 is long and strip-shaped, allowing the extrusion end 101 to have certain up and down displacement conditions.
[0026] Reference Figure 1-3 As shown, the mounting grooves are located on the left and right sides of the male terminal housing 2, and the engaging grooves are located on the upper and lower sides inside the female terminal housing 1. When you want to pull out the male terminal housing 2, you can directly pinch and press the reset springs 7 on both sides, thereby squeezing the limit unit 5 toward the fixing seat 4, so that it is disconnected from the female terminal housing 1, thereby pulling out the male terminal housing 2. It is easy and quick to operate with one hand.
[0027] The implementation principle of this application is: when the male terminal housing 2 is inserted into the female terminal housing 1, it will press against the stop head 103. As the insertion continues, the stop head 103 drives the extrusion end 101 to slide along the guide rod 9 through the connecting end 102. At the same time, the two inner sides of the female terminal housing 1 will squeeze the limiting units 5 on both sides of the male terminal housing 2 inward until the male terminal housing 2 is inserted into place. The limiting end 52 will be stuck in the limiting groove in the female terminal housing 1, thereby fixing the position of the male terminal housing 2 and preventing it from falling off. At the same time, the extrusion ends 101 on the upper and lower sides are already in a state of moving over the boundary, and are squeezed and displaced with the inclined surface on one side of the fitting groove, squeezing the upper and lower sides of the male terminal housing 2, thereby increasing the connection stability effect.
