[0028] Please refer to Figure 1-Figure 7The present invention provides an interval creepage connector 100, including a socket assembly 110 and a plug assembly 120. The socket assembly 110 includes a socket body 111 and a plurality of first terminals 112. The socket body 111 forms a receiving cavity 1111 and a plurality of blocking plates 1112 arranged at intervals in the receiving cavity 1111. An receiving cavity 1113 is formed between every two blocking plates 1112. Each first terminal 112 is respectively plugged into the receiving cavity 1113. The plug assembly 120 includes a plug body 121, a plurality of second terminals 122 and a stopper 123. The plug body 121 includes a plurality of extension columns 1211 and a notch 1212 formed therein. Each extension column 1211 is respectively plugged with a second terminal 122, and the limiting member 123 is clamped in the notch 1212 to limit the second terminal 122 in the extension column 1211. The extension column 1211 is inserted in the accommodating cavity 1113 so that each first terminal 112 is respectively connected to the second terminal 122; wherein, the limiting member 123 is protrudingly provided with a baffle 1231, and the plug body 121 is formed with a groove 1213 connected to the notch 1212, and the groove 1213 is located between every two extension columns 1211. When the limiting member 123 is clamped in the notch 1212, the baffle 1231 is embedded in the groove 1213 so that the limiting member 123 separates the second terminal 122. In a specific application, since the socket assembly 110 includes a socket body 111 and a plurality of first terminals 112, the socket body 111 forms a receiving cavity 1111 and a plurality of blocking plates 1112 spaced apart in the receiving cavity 1111, a receiving cavity 1113 is formed between every two blocking plates 1112, and each first terminal 112 is respectively inserted into the receiving cavity 1113; the plug assembly 120 includes a plug body 121, a plurality of second terminals 122 and a limiting member 123, the plug body 121 includes a plurality of extension columns 1211 and a notch 1212 is formed, each extension column 1211 is respectively inserted into the second terminal 122, and the limiting member 123 is clamped in the notch 1212 to limit the second terminal 122 in the extension column 1211 to prevent the second terminal 122 is retreated, and the extension column 1211 is inserted into the accommodating cavity 1113, so that the first terminal 112 is in contact with the second terminal 122 for electrical connection. Since the existing connector 100 pursues miniaturization and multiple pins to achieve the exchange of multiple signals, the dense pin terminals are prone to creepage problems. A baffle 1231 is protruded through the limit member 123, and the plug body 121 is formed with a groove 1213 connected to the notch 1212, and the groove 1213 is located between every two extension columns 1211. When the limit member 123 is clamped in the notch 1212, the baffle 1231 is embedded in the groove 1213, so that the limit member 123 separates the second terminal 122 and prevents the terminal from retreating, thereby preventing the creepage problem between the second terminals 122.

[0029] In a possible implementation, the stopper 123 is further provided with an abutting portion 1232, the height of which is greater than the baffle 1231. When the stopper 123 is engaged with the notch 1212, the abutting portion 1232 abuts and snaps the second terminal 122 in the extension column 1211 in the notch 1212. In a specific application, in order to prevent the terminal from retreating and causing a creepage problem, the stopper 123 is further provided with an abutting portion 1232, the height of which is greater than the baffle 1231. When the stopper 123 is engaged with the notch 1212, the abutting portion 1232 abuts and snaps the second terminal 122 in the extension column 1211 in the notch 1212, thereby limiting the retreat of the second terminal 122 relative to the extension column 1211.

[0030] In a possible embodiment, the limit member 123 also includes a base plate 1233, a U-shaped groove 12331 is formed on the base plate 1233, the abutment portion 1232 and the baffle 1231 are both protruded on the same side of the base plate 1233, the U-shaped groove 12331 is opened at the upper front of the baffle 1231, and when the limit member 123 is clamped in the slot 1212, the U-shaped groove 12331 is aligned with the interval of the extension column 1211. In specific applications, in order to improve the tightness of contact between the first terminal 112 and the second terminal 122, the limiter 123 also includes a substrate 1233, on which a U-shaped groove 12331 is formed, and the abutment portion 1232 and the baffle 1231 are both protruding on the same side of the substrate 1233, and the U-shaped groove 12331 is opened at the front upper part of the baffle 1231. When the limiter 123 is clamped in the slot 1212, the U-shaped groove 12331 is aligned with the interval of the extension column 1211. In this way, when the plug body 121 is inserted into the socket body 111, the extension column 1211 can avoid the baffle 1231 through the U-shaped groove 12331, thereby being inserted deeper into the accommodating cavity 1113, thereby making the second terminal 122 and the first terminal 112 tightly connected to improve the electrical contact performance.

In a specific application, in order to prevent the stopper 123 from accidentally sliding off from the side of the notch 1212, the interval of the groove 1213 gradually narrows toward the extension direction of the extension column 1211 to form a trapezoidal groove, and when the stopper 123 is engaged with the notch 1212, one end of the baffle 1231 is engaged with the narrowed end of the groove 1213. In this way, when the stopper 123 accidentally slides toward the extension direction of the extension column 1211, one end of the baffle 1231 is engaged with the narrowed end of the groove 1213 and locked, thereby preventing the stopper 123 from accidentally falling off, thereby improving the barrier property of the baffle 1231 to the second terminal 122.

[0032] In a possible embodiment, the limiting member 123 also includes a pre-tightening portion 1234, which is located on one side of the limiting member 123.

In specific applications, since the limit member 123 is also provided with a pre-tightening portion 1234, the pre-tightening portion 1234 is located on one side of the limit member 123, and the pre-tightening portion 1234 includes a first protrusion 12341 and a second protrusion 12342. The first protrusion 12341 is used to assist in positioning the limit member 123 in the slot 1212, thereby improving the predictability of the installation position of the limit member 123 in the slot 1212, and the second protrusion 12342 is used to clamp the limit member 123 in the slot 1212, thereby locking the limit member 123 in the slot 1212 to prevent accidental falling off.

In a specific application, in order to further restrict the displacement of the terminal, the extension column 1211 is formed with a cavity 12111 and a tongue-pressing portion 12112, the second terminal 122 is inserted into the cavity 12111, the tongue-pressing portion 12112 is elastically suspended in the cavity 12111, and when the second terminal 122 is inserted into all the cavities 12111, the tongue-pressing portion 12112 abuts and locks against one side of the second terminal 122, thereby restricting the rotation or retreat of the second terminal 122 by the tongue-pressing portion 12112 and the abutting portion 1232.
