Description

Puncture type terminal with stable positioning

Technical Field

The present invention relates to a connector terminal, and more particularly, to a piercing terminal with stable positioning.

Background

With the development of technology, connectors have been used in various fields, and generally have functions of supplying power and transmitting signals, and terminals are important parts of the connectors, and are used for forming electrical connections. In the case of an in-vehicle connector, the terminals used therein are typically piercing type terminals that make electrical connection with the wire cores in the wiring harness by piercing the wiring harness of the vehicle.

However, most of the existing piercing terminals adopt a structure with a single piercing pin, and the piercing pin is easy to be separated from the wire core due to deflection, so that the positioning stability is poor. In addition, a few piercing type terminals adopt a double piercing pin structure, but the piercing pin is a sharp end, so that the piercing pin is easy to break, and the positioning stability is poor.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, an aspect of the present invention is to provide a piercing terminal that is stably positioned, including: the connecting piece is protruded from the front end of the supporting plate, the puncturing part is protruded from the lower end of the supporting plate, the connecting pieces are electrically connected with the puncturing parts respectively, the puncturing part is provided with a supporting rib and at least three puncturing feet arranged in a row mode, the puncturing feet are protruded from the lower end of the supporting rib, and the lower ends of the puncturing feet are provided with the puncturing parts in the shape of semicircular flat plates.

Further, the connecting sheet has a connecting plate and a reinforcing rib, and the reinforcing rib protrudes from the lower end of the connecting plate.

Further, the height of the reinforcing rib is 0.2-0.4 mm.

Further, the width of the puncture foot narrows gradually from top to bottom, and the inclination of the puncture foot is 6~ 8.

Furthermore, the height of the puncture foot is 0.5-1.0 mm.

Further, the piercing terminal further includes: the public inserted sheet protrudes from the rear end of the supporting plate.

After the technical scheme is adopted, the utility model has the effects that:

1. with the puncture type terminal, even if the puncture type terminal is inclined due to the insertion and extraction force, at least one puncture pin can be ensured to be electrically connected with the wire core, and the possibility of open circuit is reduced.

2. Since the piercing portion of the piercing pin has a semicircular flat plate shape as compared with the piercing portion of the pointed end, the possibility of occurrence of breakage can be reduced.

Detailed Description

It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described by the following examples:

the utility model provides a stably positioned piercing terminal, which is shown in a combination of fig. 1 and 2 and comprises: the multifunctional puncture outfit comprises a plurality of connecting pieces 1, a support plate 2 and a plurality of puncture parts 3, wherein the connecting pieces 1 protrude from the front end of the support plate 2, the puncture parts 3 protrude from the lower end of the support plate 2, the connecting pieces 1 are electrically connected with the puncture parts 3 respectively, the puncture parts 3 are provided with support ribs 31 and at least three puncture feet 32 arranged in a row mode, the puncture feet 32 protrude from the lower end of the support ribs 31, and the lower ends of the puncture feet 32 are provided with puncture parts 320 in the shape of semicircular flat plates.

When installing above-mentioned puncture type terminal, can fix backup pad 2 inside the gluey shell of connector, connection piece 1 is arranged in the interface channel of gluey shell front end, and the puncture foot 32 of puncture portion 3 is arranged in the grafting channel of gluey shell rear end, and the car pencil inserts the inside of grafting channel, and puncture foot 32 utilizes puncture portion 320 to puncture the rubber coating of pencil, forms the electricity with the sinle silk and is connected.

Wherein the stability of the positioning is improved in that the piercing section 3 has at least three piercing feet 32 arranged in a row. In addition, even if the piercing type terminal is inclined due to the insertion and extraction force, at least one piercing pin 32 can be ensured to be electrically connected with the wire core, and the possibility of disconnection is reduced. In the present embodiment, the number of the puncture pins 32 of the puncture unit 3 is three.

Among them, the piercing part 320 of the piercing foot 32 has a semicircular flat plate shape as compared with the piercing part of the tip, so that the possibility of occurrence of breakage can be reduced.

Specifically, the connecting sheet 1 has a connecting plate 11 and a reinforcing rib 12, the reinforcing rib 12 protruding from the lower end of the connecting plate 11. The arrangement of the reinforcing ribs 12 can enhance the compressive strength of the connecting sheet 1 and reduce the possibility of deformation.

More specifically, the height of the rib 12 is 0.2 to 0.4 mm. In this embodiment, the height of the reinforcing beads 12 is 0.2 mm.

Specifically, the width of the puncture foot 32 is gradually narrowed from top to bottom, and the inclination of the puncture foot 32 is 6 to 8 °. In the present embodiment, the inclination of the piercing foot 32 is 7 °.

More specifically, the height of the puncture foot 32 is 0.5 to 1.0 mm. In the present embodiment, the height of the piercing foot 32 is 0.76 mm.

Specifically, the piercing terminal further includes: and the common inserting sheet 4 protrudes from the rear end of the supporting plate 2. When the puncture type terminal is produced, the common insertion pieces 4 of the plurality of puncture type terminals are connected with each other, and after the production is finished, the common insertion pieces 4 of the plurality of puncture type terminals are broken off to form the independent puncture type terminal.

The above-described embodiments are merely preferred examples of the present invention, and not intended to limit the scope of the utility model, so that equivalent changes or modifications in the structure, features and principles of the utility model described in the claims should be included in the claims.
