Abstract
A wiring terminal provided with a self-locking function mainly solves the problem of poor reliability of wire pressing (wire locking) due to the fact that vibration easily leads to slight loosing of bolts during using processes of existing screw type wiring terminal blocks. The wiring terminal is characterized in that an upper inner-wall of a square hole (5) of a wire pressing frame (2) is provided with reversed-V-shaped grooves (7) which are distributed at two sides of a screwed hole (6) and along the axial direction of the square hole (5). The wiring terminal is provided with the wire pressing self-locking function, guarantees reliability of electric connection between the wiring terminal and conducting wires, and has the advantages of being simple in structure and good in performance of an electric connection.
Description
Technical field
The utility model relates to the binding post that uses in the electric field, is specifically related to a kind of binding post with auto-lock function.
Background technology
The screw-type coupling terminal block is a kind of binding post commonly used in the electric field, and the locking wire principle of screw-type coupling terminal block is to promote the pressing line frame that cooperates with it through screw rotation (not moving up and down) to move up and down, thereby compresses lead (as shown in Figure 1).Described pressing line frame is that metal material is processed the integral type jointless structure, and is of patent No. ZL 94227837.2, and its advantage is seamless integral type metal structure, stacked pressing line frame can not take place because of the mutual displacement of lamination, causes sliding tooth to cause lead to get loose.But ZL 94227837.2 said integral type pressing line frames are after tighten down, because after vibration caused screw slightly loosening, binding post was progressively lost the reliability of line ball (locking wire), lead gets loose, and causes being electrically connected losing efficacy in the use.
The utility model content
In use be prone to cause screw slightly loosening in order to solve existing screw-type coupling terminal block because of vibrating; The problem of the poor reliability of line ball (locking wire); The utility model provides a kind of binding post with auto-lock function; This binding post has the line ball auto-lock function, has guaranteed the reliability that is electrically connected between binding post and the lead to have characteristics simple in structure and that electrical connection properties is good.
The technical scheme of the utility model is: a kind of binding post with auto-lock function comprises screw, pressing line frame and conducting strip; Pressing line frame is provided with in order to hold the square hole that runs through of conducting strip and lead; The screwed hole that is complementary with screw is arranged at pressing line frame top; Screw is only around the rotation of self axis and promote pressing line frame along axial-movement, and the square hole upper inner wall of pressing line frame is provided with down " V " type groove, and described " V " type groove is along the axial directional distribution of the square hole both sides at screwed hole.
The utlity model has following beneficial effect: owing to take such scheme, when screw lifting pressing line frame compressed conducting strip and lead, the reaction force of lead made pressing line frame receive tensile force; " V " type groove that falls on the pressing line frame produces deformation (v-angle diminishes); In the vibrations process, after screw is slightly loosening, pressing line frame deformation diminish (v-angle progressively recovers); Compacted to guarantee that lead continues; Realize compensation and auto-lock function automatically, guaranteed the reliable electrical connection properties of binding post, be widely used in industries such as railway, traffic, transportation.Simultaneously, screw also receives the tensile force that the pressing line frame elastic deformation is produced, and screw is also played certain locking effect.

1-screw among the figure, the 2-pressing line frame, the 3-conducting strip, the 4-lead, the 5-square hole, the 6-screwed hole, 7-is " V " type groove.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Combine Fig. 3, shown in Figure 4 by Fig. 2; A kind of binding post with auto-lock function; Comprise screw 1, pressing line frame 2 and conducting strip 3; Pressing line frame 2 is provided with in order to hold the square hole that runs through 5 of conducting strip 3 and lead 4, and the screwed hole 6 that is complementary with screw 1 is arranged at pressing line frame 2 tops, and screw 1 is only around self axis rotation and promote pressing line frame 2 along axial-movement; It is characterized in that: square hole 5 upper inner wall of pressing line frame 2 are provided with down " V " type groove 7, and described " V " type groove 7 that falls is along the axial directional distribution of square hole 5 both sides at screwed hole 6.Owing to take technique scheme, when screw 1 lifting pressing line frame 2 compressed conducting strip 3 with lead 4, the reaction force of lead 4 made pressing line frame 2 receive tensile force; " V " type groove 7 that falls on the pressing line frame 2 produces deformation (v-angle diminishes), and the upper side frame of pressing line frame 2 becomes circular arc, and pressing line frame 2 has resilience ability preferably; In the vibrations process, screw 1 slight loosening after, pressing line frame 2 deformation diminish (v-angle progressively recovers); Compacted to guarantee that lead 4 continues; Realize compensation and auto-lock function automatically, guaranteed the reliable electrical connection properties of binding post, be widely used in industries such as railway, traffic, transportation.Simultaneously, screw 1 also receives the tensile force that pressing line frame 2 elastic deformations are produced, and screw 1 is also played certain locking effect.
