Description

Opposite-insertion extending guide improved piercing terminal

Technical Field

The utility model relates to a puncture formula terminal innovation institutional advancement technique, especially to inserting extend direction modified puncture formula terminal.

Background

And the puncture type houseing terminal is directly in conductive connection without removing the outer paint of the enameled wire. One end of the enameled wire is directly riveted and pressed with the other end of the enameled wire, so that the winding wire paint layer is not stripped, the oxidation is prevented, and the rosin joint is avoided. The puncture type terminal is also called a paint stripping-free connector and a puncture type wiring terminal, is divided into five teeth, seven teeth and nine teeth, and is suitable for connecting double-strand or multi-strand enameled wires in parallel with a power supply outgoing line.

At present, in a puncture type houseing series product structure, a terminal and a board end terminal are inserted into each other to form a guide structure simply, a chamfer of 0.07mm is formed on the side face, when the board end terminal is inserted downwards, the guide effect is not large, and the actual matching is poor. Under the condition that the terminal has slight left and right deviation, the guiding function can be lost, and in the process of inserting the terminal into a board end product, the board end terminal easily and directly interferes with the piercing terminal, so that the piercing terminal is deformed, and the terminal inserting contact function is poor. In addition, the defects of the cable positioning device include poor universality, poor cable positioning precision and high product reject ratio.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a to inserting and extending the modified puncture type terminal of direction, when reducing puncture type terminal and board end product to inserting, the terminal is destroyed and is leaded to the unfavorable phenomenon of functional failure to take place by the board end product easily.

The purpose of the utility model is realized by the following technical measures: the two sides of the upper end of the supporting vertical plate are respectively and vertically connected with a side wing plate, the front sides of the two side wing plates are respectively and inwardly bent to be connected with a guide cone opening, the top edges of the two guide cone openings are respectively and obliquely bent towards the side wing plate on one side of each guide cone opening, and a cone-shaped terminal slot is formed in the top gap of the two guide cone openings.

Particularly, the bottom end of the supporting vertical plate is horizontally bent and connected with the bottom clamping plate. The middle part of the rear side of the bottom clamping plate is provided with a wire clamping groove.

In particular, the top edge of the guide cone opening is curved in an arc shape.

Particularly, the middle section of the inner side of the guide cone opening is provided with a vertical groove, and the distance between the middle parts of the gaps at the tops of the two guide cone openings is larger than the average distance.

Particularly, the top edge of the side wing plate 2 at the position corresponding to the guide cone opening at the same side is lower than the bending part of the top edge of the guide cone opening at the side.

In particular, the guide cone mouth is of an elastic structure.

The utility model discloses an advantage and effect: the plug-in device is easy to manufacture, simple in structure, safe to use, accurate and convenient to plug, stable and reliable in performance, high in positioning accuracy, capable of reducing product reject ratio and improving production efficiency. The one-time crimping conduction is completely realized, and the electrical property is stable.

Fig. 2 is a schematic view of embodiment 1 of the present invention installed on a terminal plate structure.

Fig. 3 is a schematic view of a partial unit structure in fig. 2.

The reference numerals include:

the device comprises a guide cone opening 1, a side wing plate 2, a supporting vertical plate 3, a bottom clamping plate 4, a terminal plate 5, a socket 51 and a terminal clamping groove 52.

Detailed Description

The utility model discloses the principle lies in, and the terminal grafting structure is punctured in the improvement, strengthens direction steadiness and grafting accuracy, through promoting stability in order to improve the product quality.

The present invention will be further explained with reference to the drawings and examples.

Example 1: as shown in fig. 1, two sides of the upper end of the supporting vertical plate 3 are respectively and vertically connected with a side wing plate 2, the front sides of the two side wing plates 2 are respectively and inwardly bent to be connected with a guiding cone 1, the top edges of the two guiding cone 1 are respectively and obliquely bent towards the side wing plate 2 on one side, and a cone-shaped terminal slot is formed in the gap between the tops of the two guiding cone 1.

In the foregoing, the bottom end of the supporting vertical plate 3 is horizontally bent and connected with the bottom clamping plate 4. The middle part of the rear side of the bottom clamping plate 4 is provided with a wire clamping groove.

In the foregoing, the top edge of the guide cone 1 is curved in an arc shape.

In the foregoing, the middle section of the inner side of the guide cone 1 is provided with a vertical groove, and the distance between the middle parts of the gaps at the tops of the two guide cone 1 is larger than the average distance.

In the above, the top edge of the side wing plate 2 at the position corresponding to the same-side guide cone opening 1 is lower than the bent part of the top edge of the side guide cone opening 1.

In the foregoing, the guiding cone 1 is an elastic structure.

In the embodiment of the present invention, when the installation and application are performed, as shown in fig. 2 and 3, the vertical supporting plate 3 and the side wing plate 2 are embedded into the terminal slot 52 reserved on the terminal board 5, wherein the pair of guiding tapers 1 is opposite to the socket 51. In application, the connection wire is directly inserted into the gap between the pair of guiding tapers 1 from the insertion opening 51 and is inserted in place before the guiding tapers 1 are righted and clamped, and the puncture type terminal connection is completed.

The embodiment of the utility model provides an in, set up elasticity full contact at the original interface position innovation of puncture type houseing terminal and extend guide structure, not only replace current simple chamfer structure to increase the direction performance, the extension terminal inserts, when guaranteeing that the board end terminal inserts, can correctly lead, has fine guide effect with the board end is equipped with in fact, does not have the bad emergence. The rationality and the reliability of the terminal collocation with the board end are increased, and the stable quality of the terminal product is ensured.
