Description

Plug-in terminal supporting opposite insertion of terminals of same type

Technical Field

The present application relates to a plug terminal used in an electrical connection device, and more particularly, to a plug terminal supporting plug-in of terminals of the same type.

Background

In the field of electrical connection technology, terminals are mounted in the plastic housing of a connector. When mating connectors (e.g., a plug connector and a receptacle connector) are mated together, the terminals within the connectors are correspondingly electrically connected.

With conventional connectors, terminals having a mating relationship are generally used in two connectors that are mated. For example, the female pin 100A shown in fig. 1A is used for the plug connector, and the male pin 100B shown in fig. 1B is used for the receptacle connector. Due to the different structures of the male pin and the female pin, the male pin and the female pin need to be designed and manufactured separately. In actual assembly and use, due to the fact that terminals which need to be installed into the mating connector are different, the problem that the male pin is mistakenly installed in the female-end inserting core or the plastic shell (namely, the inserting core or the plastic shell which is used for accommodating the female pin) or the female pin is mistakenly installed in the male-end inserting core or the plastic shell is inevitably caused, and therefore production efficiency of an assembly link is affected. In addition, because the male contact pin and the female contact pin have different structures, the corresponding inserting cores or plastic shells are also different, and two sets of dies need to be opened for the inserting cores or the plastic shells.

The invention is further described below with reference to the accompanying drawings.

First embodiment

Fig. 2 is a perspective view of a mating terminal 200 according to a first embodiment of the present invention. As shown in fig. 2, the mating terminal 200 has a terminal end (lower end in fig. 2) for wiring and a mating end (upper end in fig. 2) for mating with another terminal. The mating terminal 200 includes a terminal base 210 provided on one side of the terminal, and a mating portion 250 extending from the terminal base 210 in a mating direction. The wiring base 210 is illustrated as a wiring frame structure. It will be appreciated that various wiring techniques known in the art may be implemented in the frame portion, such as in-line wiring, cage spring return wiring, etc., and that depending on the wiring technique, the frame may have different configurations and be provided with spring tabs, etc., as needed to effect crimping. Thus, the specific wiring techniques of the wiring base 210, at least in some embodiments of the present application, do not constitute a limitation on the invention disclosed herein.

As further shown in fig. 2, the plug portion 250 includes a blade structure 251 extending from a first location of the wiring base 210, and a clip structure 255 extending from a second location of the wiring base 210, the second location being different from the first location. Further, the wiring base 210 is a frame surrounded by a plurality of side walls, the blade structure 251 extends from the first side wall 211 of the frame, and the clip structure 255 extends from the second side wall 212 of the frame. The first sidewall 211 and the second sidewall 212 are opposite.

As further shown in fig. 2, the second sidewall 212 is a double-layer lamination, and includes an inner layer 212B and an outer layer 212A (where "inner" and "outer" are relative to the inside and outside of the terminal frame), the elastic piece clamping structure 255 includes a first elastic piece (or referred to as a first elastic arm) 255A and a second elastic piece (or referred to as a second elastic arm) 255B respectively extending from the outer layer 212A and the inner layer 212B of the second sidewall 212, and the number of the first elastic piece 255A and the number of the second elastic piece 255B are three (the number may also be one, or other natural numbers). The two rows of spring plates are bent from the base part to face each other to shorten the interval and then bent to face each other to increase the interval again, thereby forming a nip with sufficient clamping force.

Fig. 3A is a perspective view of the jack terminals 200 shown in fig. 2 in a state of being used in pairs and separated from each other.

Fig. 3B is a perspective view of the jack terminals 200 shown in fig. 2 in a state of being used in pairs and being plugged into each other.

Fig. 3C is a side view of the jack terminals 200 of fig. 2 in a mated configuration and mated with one another.

As shown in fig. 3A,

mating terminals

200A and 200B (both having the configuration of mating terminal 200) are in a symmetrical spatial relationship when mated, in which the blade structure of mating terminal 200A faces the blade structure of mating terminal 200B and the blade structure of mating terminal 200A also faces the blade structure of mating terminal 200B. As shown in fig. 3B and 3C, when mating terminal 200A and mating terminal 200B are mated together (e.g., mating terminal 200A and mating terminal 200B are each mounted in a connector and the connectors are mated together), the blade structure of mating terminal 200A below is received and retained by the blade structure of mating terminal 200B above, and the blade structure of mating terminal 200A above is received and retained by the blade structure of mating terminal 200B below. In this way, two

jack terminals

200A and 200B of the same construction achieve a reliable jack relationship, establishing mechanical contact and electrical connection.

The plug terminal 200 shown in fig. 2 may be manufactured from a conductive sheet material (e.g., a metal sheet). For example, fig. 4 provides a schematic illustration of a stamped and formed sheet metal material used to make the jack terminal shown in fig. 2. As can be seen from fig. 4, the width of the portion of the sheet material for current flow (corresponding to the

reference numerals

255A, 255B, 251) is a considerable proportion of the total width of the sheet material, and therefore, the current utilization of the material is improved and the cost per unit current is reduced compared to the electrical connection based on the male pins and the female pins. As can also be seen in fig. 2, 3A and 4, the outer layer 212A is connected to the other side walls of the frame, while the inner layer 212B is formed by folding one end of the sheet material constituting the frame inward.

Second embodiment

Fig. 5A is a perspective view of a jack terminal 500 (two upper and lower) according to a second embodiment of the present invention, and fig. 5B is a schematic view of the two jack terminals shown in fig. 5A in a plugged state. The jack terminal 500 of FIG. 5A has a blade structure 551 and a clip structure 555 similar to the jack terminal of FIG. 2

As can be seen by comparing fig. 2 with fig. 5A-5B, the inner layer 512A in fig. 5A is attached to the other side walls of the frame, while the outer layer 512B is formed by folding one end of the sheet material constituting the frame outward. By adopting a different crimping manner from that of fig. 2, the wiring base portion 510 of the plug terminal of fig. 5A is more flat as a whole in the case where the blade structure and the clip structure are equally spaced.

As shown in fig. 5B, when the jack terminal 500A and the jack terminal 500B (each having the configuration of the jack terminal 500) are used in pair, a reliable plugging relationship is achieved, thereby establishing mechanical contact and electrical connection.

Referring to fig. 2 in addition to fig. 6A-6B, it can be seen that a male pin structure 651 extends from one side wall of the frame of the wiring base of the jack terminal 600 and a female pin structure 655 extends from the opposite side wall. As shown in fig. 6B, when

mating terminals

600A and 600B (each having the configuration of mating terminal 600) are mated together in a symmetrical manner, the respective male pin structures 651 and the mating female pin structures 655 form a secure mating relationship, thereby establishing mechanical contact and electrical connection.

With further reference to fig. 7A, it can be seen that the first and second

resilient structures

751, 752 each include a pair of resilient arms disposed along the side wall edges of the frame, wherein one resilient arm has a distal end that is bent inwardly toward the frame and the other resilient arm has a distal end that is bent outwardly toward the frame.

With further reference to fig. 7A, it can be seen that the third resilient tab structure 753 includes a plurality of resilient arms disposed along a sidewall edge of the frame, each resilient arm of the plurality of resilient arms beginning at a base portion, bending first inward into the frame, and then outward from the frame.

As will be understood from fig. 7A and 7B, when two mating terminals 700 are mated and inserted in a spatially symmetrical manner, the pair of resilient arms of the first side wall of the upper mating terminal 700A and the pair of resilient arms of the second side wall of the lower mating terminal 700B elastically abut, the pair of resilient arms of the second side wall of the upper mating terminal 700A and the pair of resilient arms of the first wall of the lower mating terminal 700B elastically abut, and the plurality of resilient arms of the third side wall of the upper mating terminal 700A and the plurality of resilient arms of the third side wall of the lower mating terminal 700B elastically abut.
