Description

Connector assembly and female terminal using the connector assembly

The present invention relates to a new type of connector assembly which can improve the contact reliability of a male terminal and a female terminal.

In general, connector assemblies are mainly used in electronic products and are devices used to connect signals or power between two parts.

These connector assemblies are provided as a pair of male connectors and female connectors, and the two parts are electrically connected to each other by the mating of the male connector and the female connector.

The above-mentioned male connector comprises a male housing and a male terminal provided within the male housing, and the above-mentioned female connector comprises a female housing and a female terminal provided within the female housing.

The above-mentioned male terminal and female terminal should be prevented from being separated from each other while connected to each other, or from being momentarily released from contact. Accordingly, conventionally, a portion of the female terminal is formed by bending it to provide a spring structure that elastically deforms in a direction perpendicular to the direction in which the male terminal is inserted, thereby stably maintaining the connection between them. This is as disclosed in Registered Utility Model No. 20-0437689, Publication No. 10-2009-0073857, Publication No. 10-2009-0073879, Publication No. 10-2012-0037199, etc.

However, the connector assembly according to the above-mentioned conventional technology had a problem in that when the male connector and the female connector were repeatedly connected and disconnected, the female terminal became deformed and the elastic restoring force weakened, and as a result, the fixing force between the two terminals was reduced and the occurrence of poor contact caused a carbonization phenomenon at the contact area between each other.

In particular, since the above-mentioned male terminal is formed to be connected in a manner that presses the bending portion of the above-mentioned female terminal, the spring tension of the bending portion was bound to be reduced.

In addition, there was a problem in that the connector assembly according to the prior art was made so that the male terminal and the female terminal were in contact with each other at only one location and thus there was a high risk of defects occurring at the contact location or temporary detachment occurring due to external impact.

In addition, when the female terminal is inserted in an inclined state during the process of inserting the male terminal into the female connector, there is a frequent occurrence of the male terminal hitting the folded portion of the female terminal and damaging the folded portion, which causes a problem in that the elasticity of the folded portion of the female terminal is weakened.

Next, a preferred embodiment of the connector assembly of the present invention is described with reference to the attached FIGS. 1 to 19.

The attached Fig. 1 is a perspective view of a connector assembly according to an embodiment of the present invention, and Fig. 2 is an exploded perspective view of a connector assembly according to an embodiment of the present invention. In addition, Fig. 3 is a cross-sectional view of a connector assembly according to an embodiment of the present invention.

As shown in these drawings, the connector assembly according to the embodiment of the present invention allows the male terminal (220) to come into contact with a non-bent portion, rather than a bent or protruding portion, of the female terminal (110), thereby allowing stable contact between the male terminal (220) and the female terminal (120).

The connector assembly according to this embodiment of the present invention includes a female connector (100) and a male connector (200), and each component will be described in more detail as follows.

First, the female connector (100) is described.

The above female connector (100) is connected to a power source or electrical component and serves to transmit power or a signal from the electrical component.

The above female connector (100) is composed of a female housing (110) and a female terminal (120).

The female housing (110) forming the above female connector (100) forms the exterior of the female connector (100).

In the above female housing (110), a first installation groove (111) in which a female terminal (120) is installed is formed to penetrate the front and rear of the female housing (110).

The above first installation groove (111) may be formed in one or two or more. Although not shown, when the above first installation groove (111) is provided in multiple numbers, at least some of the first installation grooves (111) among the first installation grooves (111) may be formed in a different size from the remaining ones.

As shown in FIGS. 3 and 4, a lance (112) is provided within the first installation groove (111). The lance (112) is formed in a cantilever shape so as to be elastically deformable on the bottom surface (or upper surface) within the first installation groove (111). A restraining projection (112a) protruding into the first installation groove (111) is formed on the lance (112), and the restraining projection (112a) acts to restrain a female terminal (120) to be described later.

Among the upper portions (the portions protruding into the first installation grooves) of the restraining projections (112a) forming the above lance (112), the corners on the side where the mail terminal (220) to be described later is inserted are formed to be inclined or rounded. Due to this inclined corner shape, when the mail terminal (220) is inserted, it can be gradually pressed downward by contact with the mail terminal (220).

The female terminal (120) forming the above female connector (100) is a portion electrically connected to the male terminal (220) to be described later.

The above female terminal (120) is installed in the first installation groove (111) of the female housing (110) and is formed to be connected to the male terminal (220) of the male connector (200) to be described later.

The above female terminal (120) may be provided in one or two or more. For example, a plurality of first installation grooves (111) are formed within the female housing (110), and the female terminal (120) may be provided in multiple numbers and mounted so as to penetrate each of the first installation grooves (111).

The number of the female terminals (120) and the first installation grooves (111) may not match each other. For example, the number of the first installation grooves (111) may be greater than the number of the female terminals (120).

A restraint hole (121a) is formed on the bottom surface of the female terminal (120). A restraint projection (112a) of a lance (112) provided on the bottom of the first installation groove (111) is inserted into the restraint hole (121a) to restrain the female terminal (120), thereby preventing it from being separated forward within the first installation groove (111).

As shown in the cross-sectional view of Fig. 4, the perspective views of Figs. 5 to 8, and the front view of Fig. 9, the female terminal (120) includes a horizontal end (121) and a spring contact end (122).

The above horizontal section (121) is a portion forming the bottom surface of the female terminal (120) and is formed horizontally with the bottom surface or upper surface within the first installation groove (111).

On both sides of the horizontal section (121), side walls (123) may be formed to form both side walls of the female terminal (120) while being bent from the horizontal section (121). On the upper side of the horizontal section (121), an upper wall (124) may be formed to form the upper surface of the female terminal (120) while being bent from at least one of the two side walls (123).

As shown in Fig. 4, the spring contact section (122) may be formed by a first bend section (122a) that extends while being bent from the tip (opposite side to the mail terminal) of the horizontal section (121), and a second bend section (122b) that extends while being bent from the first bend section (122a).

The above first bending section (122a) can be defined as a section from the horizontal section (121) to the second bending section (122b).

The above first bending section (122a) is formed to be bent at an angle exceeding 90° from the horizontal section (121). That is, the above first bending section (122a) is formed to be bent from the front end of the above horizontal section (121) and have its end positioned further rearward than the bending portion. At this time, the above first bending section (122a) is formed to extend so as to gradually slope upward as it goes rearward.

The above first bending section (122a) is formed in a round shape and is bent from the horizontal section (121). As a result, the first bending section (122a) can provide elastic restoring force by being pressed downward and restored upward by the bending portion.

In the above first bending section (122a), a through hole (122c) is formed through which a mail terminal (220) to be described later passes. The bottom surface of the through hole (122c) is positioned at or higher than the boundary between the first bending section (122a) and the horizontal section (121), and the upper surface of the through hole (122c) is formed so as not to reach the bending section as the second bending section (122b) to be described later is extended (lower than the highest position of the female terminal).

The above second bending section (122b) can be defined as a section from the bending section at the end of the first bending section (122a) to the rear end.

The above second bending section (122b) is formed by extending from the first bending section (122a) so that it becomes closer to the horizontal section (121) as it bends toward the end. That is, the second bending section (122b) is formed by extending from the first bending section (122a) so as to gradually slope downward.

The end of the second bending member (122b) is formed so as to be positioned lower than the upper surface within the through hole (122c). That is, the structure of the second bending member (122b) allows the mail terminal (220) that passes through the through hole (122c) and is connected to either the upper surface within the through hole (122c) or the second bending member (122b).

Meanwhile, an anti-lifting protrusion (113) is formed in the first installation groove (111) of the female housing (110) to prevent the end of the second bending section (122b) from being lifted. That is, since the anti-lifting protrusion (113) prevents excessive lifting of the second bending section (122b), the male terminal (220), which will be described later, can accurately contact the second bending section (122b) after passing through the through hole (122c).

At this time, the above-mentioned anti-slip threshold (113) is formed to be positioned at a height equal to or lower than the upper surface within the above-mentioned through hole (122c).

In addition, a closing portion (125) is formed on the front surface of the female terminal (120) to block the portion between the connection portion with the second bend (122b) of the first bend (122a) and the through hole (122c). That is, since the open front surface of the female terminal (120) is closed by the closing portion (125) except for the portion where the through hole (122c) is located, there is a risk that the connection portion (start portion of the second bend) between the first bend (122a) and the second bend (122b) may be undesirably damaged or deformed.

For example, the closing part (125) can prevent the phenomenon of the male terminal (220) being inserted toward the highest part of the spring contact end (122) of the female housing (110) and causing the corresponding part to be deformed.

The above closing portion (125) is folded from at least one of the two side walls forming the female terminal (120) to the other side wall to close an open portion above the through hole (122c) on the front surface of the female terminal (120).

Meanwhile, the unexplained symbol 130 is used as a lever to completely connect the male housing (210) within the female housing (110).

The following describes the mail connector (200).

The above-mentioned male connector (200) is connected to a power source or electrical component different from the female connector (100) and serves to receive or transmit a signal or power from the female connector (100).

As an example, the female connector (100) can be connected to a power source, and the male connector (200) can be connected to the electrical component.

As another example, the female connector (100) may be connected to one electrical component, and the male connector (200) may be connected to a power source.

As another example, the female connector (100) may be connected to one electrical component, and the male connector (200) may be connected to another electrical component.

The above-mentioned mail connector (200) is composed of a mail terminal (220) (see FIGS. 7 and 8) connected to the female terminal (120) of the above-mentioned female connector (100), and a mail housing (210) (see FIGS. 3 to 5) in which the above-mentioned mail terminal (220) is installed.

The above mail housing (210) forms the exterior of the mail connector (200).

The front end side (opposite to the female housing) of the above-described male housing (210) is formed so as to provide a mounting space. At least a portion of the female housing (110) is mounted while being accommodated in the mounting space. That is, the female housing (110) is formed so that at least a portion of the front end is inserted and coupled into the mounting space of the male housing (210). For example, the female housing (110) may be entirely inserted into the mounting space of the male housing (210), or only a portion of the female housing (110) may be inserted into the mounting space of the male housing (110).

A second installation groove (211) in which the mail terminal (220) is installed is formed at the rear end of the above mail housing (210).

The above second installation grooves (211) may be formed in one or two or more. Although not shown, when the above second installation grooves (211) are provided in multiples, at least some of the second installation grooves (211) may be formed in a different size from the remaining ones.

The above-mentioned male housing (210) has a support projection (212) formed to support the bottom surface of the lance (112) while being inserted into the above-mentioned female housing (110). That is, when the above-mentioned male housing (210) and the above-mentioned female housing (110) are coupled to each other, the support projection (212) is positioned to support the bottom surface of the lance (112), thereby preventing unwanted sagging (downward tilting) of the lance (112). As a result, the lance (112) can be maintained in a state of supporting the bottom of the below-mentioned male terminal (220).

The male terminal (220) forming the above-mentioned mail connector (200) is provided for electrical connection with the female terminal (120).

The above mail terminal (220) is composed of a fixed end (221) fixed within the second installation groove (211) and a contact end (222) formed by protruding in front of the fixed end (on the side facing the female terminal) and penetrating through the second installation groove (211) to reach the mounting space within the male housing (210). At this time, the fixed end (221) can be connected to a power line, a circuit board, or an electrical component.

The contact end (222) of the above mail terminal (220) has a length sufficient to be inserted into the first installation groove (111) of the female housing (110) accommodated in the mounting space of the above mail housing (210), and the end edge of the contact end (222) is formed to slope downward as it goes forward.

The contact end (222) of the above-described mail terminal (220) is configured to penetrate the through-hole (122c) of the female terminal (120) installed in the first installation groove (111) and to come into contact with the non-bent portion of the female terminal (120). More specifically, the contact end (222) of the above-described male terminal (220) is inserted into the female terminal (120) by penetrating the through-hole (122c) and then comes into contact with the upper surface of the through-hole (122c) formed in the first bending end (122a) and the second bending end (122b), respectively.

Accordingly, even if the contact between the contact end (222) of the mail terminal (220) and the upper surface within the through hole (122c) or the contact end of the mail terminal (220) and the second bending end (122b) is momentarily released, the other contact end maintains contact, so that a short circuit phenomenon between the two terminals (120, 220) can be prevented.

In addition, the bottom surface of the contact section (222) is configured to contact the top surface of the lance (112) to provide a pressing force. That is, as the restraining projection (112a) of the lance (112) supports the bottom surface of the contact section (222) and prevents sagging, the contact section (222) of the male terminal (220) can be stably maintained in contact with the two contact portions of the female terminal (120).

Meanwhile, a front housing (230) is provided at the front of the mail housing (210) to support the tip of the mail terminal (220). The tip of the mail terminal (220) is installed to penetrate the front housing (230) and is supported when combined with the female terminal (120). The front housing (230) is provided as a separate component from the mail housing (210).

In addition, when the front housing (230) is provided separately, the support protrusion (212) can be formed to protrude on the front of the front housing (230).

Below, the connection process between two connectors (100, 200) of the connector assembly according to the embodiment of the present invention described above is described in more detail with reference to the attached FIGS. 10 to 12.

First, each terminal (120, 220) of each connector (100, 200) is provided in a fixed state within each housing (110, 210) in a state directly connected to a circuit board, wire, or circuit component, or connected by wire.

Here, the female terminal (120) of the female connector (100) is provided fixedly in a state where it is inserted into the first installation groove (111) of the female housing (110) and its fixing projection (112a) of the lance (112) is received in its fixing hole (121a). The male terminal (220) of the male connector (100) is provided fixedly in a state where it is inserted into the second installation groove (211) of the male housing (210) and its contact end (222) forming its tip protrudes into the front mounting space in the male housing (210).

Attached Figure 10 shows the state before the mail terminal (220) is connected to the female terminal (120).

And, the male connector (200) and the female connector (100) provided as described above are combined with each other by their shape. That is, they are combined with each other by inserting the tip of the female housing (110) into the male housing (210).

As shown in Fig. 11, when the tip of the female housing (110) is inserted into the male housing (210), the contact end (222) of the male terminal (220) protruding into the mounting space in the male housing (210) is inserted into the first installation groove of the female housing (110).

Subsequently, the contact end (222) of the mail terminal (220) passes through the through hole (122c) of the female terminal (120) installed in the first installation groove (111) and is accommodated in the space between the horizontal end of the female terminal (120) and the spring contact end (122). At this time, since the opening above the through hole (122c) among the open front surfaces of the female terminal (120) is blocked by the closing portion (125), the contact end (222) is inserted only into the portion where the through hole (122c) is formed. As a result, the problem of the contact end (222) being inserted into the connection portion between the first bending end (122a) and the second bending end (122b) and hitting and damaging the connection portion can be prevented.

In addition, in the process of the mail terminal (220) being received between the horizontal section (121) and the spring contact section (122) by penetrating through the through hole (122c), the front end portion forming the contact section (222) of the mail terminal (220) comes into contact with the lower surface of the second fold section (122b) of the spring contact section (122), and the rear end portion (or, center portion) forming the contact section (222) comes into contact with the upper surface within the through hole (122c) formed in the first fold section (122a).

In particular, when the front end of the contact section (222) comes into contact with the bottom surface of the second bend section (122b), the rear end of the second bend section (122b) may be deformed to bend upward, but since the anti-lifting protrusion (113) is formed protrudingly within the first installation groove (111) to prevent the rear end of the second bend section (122b) from being lifted upward, deformation is prevented.

In addition, when the contact end (222) of the mail terminal (220) passes through the through hole (122c) (or is passing through it), it is placed on the upper surface of the restraining projection (112a) that protrudes through the bottom surface of the female terminal (120). That is, the contact end (222) of the male terminal (220) is lifted upward by the elastic restoring force of the restraining projection (112a), and thereby the contact end (222) of the male terminal (220) can maintain a state in which the front and rear end portions (or the central portions) are in contact with the first bending end (122a) and the second bending end (122b) of the spring contact end (122) located above it, respectively. This is as shown in the attached FIG. 12.

In addition, while the tip of the female housing (110) is accommodated in the mounting space of the male housing (210), the support projection (212) located in the mounting space supports the bottom surface of the lance (112). Accordingly, the lance (112) is prevented from undesirably sagging, and the contact end (222) of the male terminal (220) can be maintained in a state in which it is lifted upward by the lance (112).

Ultimately, the connector assembly of the present invention enables the maintenance of a stable connection state without deformation of the female terminal (120) even when the connection and separation between the two connectors (100, 200) are repeated.

In addition, the connector assembly of the present invention can maintain the male terminal (220) connected to the female terminal (120) by the lance (112) that fixes the female terminal (120).

In addition, since the connector assembly of the present invention has a plurality of contact points between the female terminal (120) and the male terminal (220), even if a defect occurs in one contact point or a detachment occurs in one contact point, the problem of the connection between the two terminals (120, 220) being released is prevented.

In addition, the connector assembly of the present invention prevents damage to the bending portion of the female terminal (120) by preventing the male terminal (220) from hitting the bending portion of the female terminal (120) during the process of inserting the male terminal (220) into the female terminal (120).

Meanwhile, the connector assembly of the present invention can be implemented in various forms other than the form of the above-described embodiment.

As an example, the lance (112) may not be provided in the female housing (110). Even with this structure, the male terminal (220) can stably contact the non-bending portion of the female terminal (120) while penetrating the female terminal (120).

As another example, the supporting projection (212) may not be formed on the mail housing (210). Even with this structure, the lance (112) can stably support the bottom surface of the mail terminal (220) while having its own restoring force.

In the above, even though all the components constituting the embodiments according to the present invention have been described as being combined as one or operating in combination, the present invention is not necessarily limited to these embodiments. That is, within the scope of the purpose of the present invention, all of the components may be selectively combined and operated one or more times. In addition, the terms "include," "compose," or "have" described above, unless specifically stated to the contrary, mean that the corresponding component may be inherent, and therefore should be interpreted as including other components rather than excluding other components. All terms, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the art to which the present invention belongs, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted as being consistent with the contextual meaning of the related technology, and shall not be interpreted in an ideal or excessively formal meaning unless explicitly defined in the present invention.

The above description is merely an illustrative description of the technical idea of the present invention, and those skilled in the art will appreciate that various modifications and variations may be made without departing from the essential characteristics of the present invention. Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to explain it, and the scope of the technical idea of the present invention is not limited by these embodiments. The protection scope of the present invention should be interpreted by the following claims, and all technical ideas within a scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
