Hereinafter, a plug connector according to an embodiment of the present invention will be described with reference to fig. 2 to 5.

Fig. 2 is a perspective view showing a plug connector according to an embodiment of the present invention, fig. 3 is a perspective view showing a mold part of fig. 2, fig. 4 is a perspective view showing a plug terminal of fig. 2, and fig. 5 is an exploded perspective view for explaining a connector assembly according to an embodiment of the present invention.

Referring to fig. 2 to 4, the plug connector 10 includes a mold part 100 and first to

fourth plug terminals

201, 202, 203, 204.

The mold part 100 may include a base part 101 and first to

fourth wall parts

110, 120, 130, 140. The first to

fourth wall portions

110, 120, 130, 140 may have patterns respectively protruding from the upper surface of the base portion 101.

Specifically, the first wall portion 110 may be elongated in the first direction X on the base portion 101. The third wall portion 130 may be elongated in a second direction Y intersecting the first direction X on the base portion 101. The second wall portion 120 may be opposite to the first wall portion 110 on the base portion 101. The fourth wall portion 140 may be opposite to the third wall portion 130 on the base portion 101. At this time, the third wall portion 130 may be connected to one side of the first wall portion 110 and one side of the second wall portion 120. In addition, the fourth wall portion 140 may be connected to the other side of the first wall portion 110 and the other side of the second wall portion 120.

Accordingly, the base portion 101 and the first to

fourth wall portions

110, 120, 130, 140 may be connected to each other to form the mold portion 100.

The first to

fourth wall portions

110, 120, 130, 140 may define a space in which the plug connector 10 is fastened to the receptacle connector 20. For example, the first to fourth wall portions 110 to 140 may be formed along the edge of the upper surface of the base portion 101. Therefore, a space can be formed on the central portion of the upper surface of the base portion 101, and a part of the receptacle connector 20 can be inserted into this space, so that the plug connector 10 and the receptacle connector 20 can be fastened together.

The mold part 100 may be formed of an insulator including resin, epoxy resin, and the like, but is not limited thereto.

In addition, the mold part 100 and the plug terminal 200 may be integrally formed, but is not limited thereto.

The first plug terminal 201 may be formed on the first wall portion 110 of the mold portion 100, and the second plug terminal 202 may be formed on the second wall portion 120 of the mold portion 100. For convenience of explanation, the following description will be made centering on the first plug terminal 201 arranged on the first wall portion 110.

The first plug terminal 201 is formed at the first wall portion 110, and the plug connector 10 may be mounted on a substrate (not shown) using a method such as soldering. Thus, the connector 10 can be fixed to the substrate. In addition, the plug connector 10 may be electrically connected to a substrate. That is, the first plug terminal 201 may input an output power electrical signal or a data electrical signal.

Specifically, when the first plug terminal 201 inputs and outputs a power supply electrical signal, the first plug terminal 201 can supply power to a board or the like on which the plug connector 10 is disposed. In contrast, when the first plug terminal 201 inputs/outputs an electrical data signal, the first plug terminal 201 can transmit data to an electrical component or the like disposed in another region of the substrate on which the plug connector 10 is disposed.

The first plug terminal 201 may be formed of a metal substance including copper or the like, but the technical idea of the present invention is not limited thereto.

The third plug terminal 203 and the fourth plug terminal 204 may be disposed on the third wall 130 and the fourth wall 140 to input and output a power electrical signal or a data electrical signal. For example, the third plug terminal 203 and the fourth plug terminal 204 may include power terminals for inputting and outputting power electrical signals, or signal terminals for inputting and outputting data electrical signals.

Specifically, the power supply terminal of the third plug terminal 203 and the power supply terminal of the fourth plug terminal 204 can supply power to a board or the like on which the plug connector 10 is disposed. In contrast, the signal terminals of the third plug terminal 203 and the signal terminals of the fourth plug terminal 204 can transmit data to an electric component or the like disposed in another region of the substrate on which the plug connector 10 is disposed.

The third plug terminal 203 and the fourth plug terminal 204 may be formed of a metal substance including copper or the like, but the technical idea of the present invention is not limited thereto.

The first plug terminal 201 may include a first contact portion 210, a second contact portion 220, and a third contact portion 230.

The second contact portion 220 may be connected to one side of the first contact portion 210 by a first connection portion 218, and the third contact portion 230 may be connected to the other side of the first contact portion 210 by a second connection portion 219.

Coupling

portions

229, 239 may be protrudingly formed at an outer circumferential surface of the second contact portion 220 and an outer circumferential surface of the third contact portion 230, respectively, to be coupled with the mating connector.

In addition, the first connection portion 218 may be extended from one side of the first extension portion 213 of the first contact portion 210 to be described later to be connected to the second contact portion 220, and the second connection portion 219 may be extended from the other side of the first extension portion 213 of the first contact portion 210 to be described later to be connected to the third contact portion 230.

In addition, the first connection portion 218 is formed in the following manner: the length of the second direction Y connected with the second contact portion 220 is longer than the length of the first direction X connected with the first contact portion 210, and the second connection portion 219 may be formed in the following manner: the length of the second direction Y connected to the third contact portion 230 is longer than the length of the first direction X connected to the first contact portion 210.

Since the first connection portion 218 and the second connection portion 219 face each other and have the same shape, only the second connection portion 219 will be described.

The second connection part 219 may be connected to the other side of the first extension part 213 of the first contact part 210 by a first bent connection part 219a of the second connection part 219, may be connected to a third plate part 231 of a third contact part 230, which will be described later, by a second bent connection part 219b of the second connection part 219, and may be connected to a second bent part 234 of the third contact part 230 by a third bent connection part 219c of the second connection part 219.

That is, the first extension portion 213 of the first contact portion 210, which will be described later, is connected to one side of the second connection portion 219, and the third plate portion 231 of the third contact portion 230, which will be described later, and the second bent portion 234 may be connected to the other side of the second connection portion 219.

The second connection part 219 may be formed such that the length of the upper surface of the second connection part 219, on which a second bent connection part 219b connected to a third plate part 231 of a third contact part 230, which will be described later, is formed, is longer than the length of the lower surface of the second connection part 219, on which a third bent connection part 219c connected to a second bent part 234 of the third contact part 230 is formed.

Further, the first to third bent connecting

portions

219a, 219b, and 219c are connected so that the cross-sections of the first to third bent connecting

portions

219a, 219b, and 219c are larger than the cross-section of the central portion of the second connecting portion, whereby stress concentration can be relaxed at the connecting portion connecting the second connecting portion 219, and resistance can be improved.

Accordingly, the second bent portion 234 is bent and extended at a point where the second connection portion 219 is connected to the third contact portion 230, and may be connected to a third mounting portion 235, which will be described later.

That is, in the second bent portion 234, the second connection portion 219 and the third contact portion 230 overlap in the third direction Z, and the second bent portion 234 is bent and extended at a point where the second connection portion 219 and the third contact portion 230 are connected, so that the third mounting portion 235 may be protrudingly formed.

Thus, when the third contact portion 230 receives an external force in the first direction X when coupled with the mating connector, the second bent portion 234 connected to the first plate portion 231 of the third contact portion 230, which will be described later, is supported in the second direction Y by the second connecting portion 219 and the mold portion 100, and can be supported in the first direction X by the third mounting portion 235, which will be described later, and the mold portion 100, which are mounted on the substrate for support.

In addition, a fastening portion 204a may be formed in the fourth plug terminal 204 to be fastened and fixed with the mating connector, and an engaging portion 204b may be formed in the fastening portion 204a in an inclined form to be easily coupled and separated with the mating connector.

In addition, the mounting portion 204c of the fourth plug terminal 204 may be protrudingly formed and may be exposed from a lower portion of the fourth wall portion 140. That is, it may protrude from the lower surface of the mold part 100 to be exposed, and the mounting part of the fourth plug terminal may mount the plug connector 10 on a substrate (not shown) using a method such as soldering.

Further, the support portion 146 may be formed to protrude from the fourth wall portion 140 to one side on the upper side of the mounting portion 204c of the fourth plug terminal 204, and the support portion 146 may be formed to surround a part of the upper side of the mounting portion 204c of the fourth plug terminal 204 and the lower side may be formed in an open form, so that the plug connector 10 may be more firmly supported when the plug connector 10 is mounted on the substrate.

In addition, the third plug terminal 203 is opposed to the fourth plug terminal 204 and has the same shape.

Referring to fig. 5, the plug connector 10 and its corresponding receptacle connector 20 may be fastened to each other to form an electrical connector assembly. The plug connector 10 of fig. 5 is a version of the plug connector 10 of fig. 2 after being flipped over.

As shown, the first to

fourth wall portions

110, 120, 130, 140 of the plug connector 10 may be respectively inserted into corresponding spaces of the receptacle connector 20. Accordingly, the plug connector 10 and the receptacle connector 20 can be fastened to each other to form an assembly of the electrical connector. However, the technical idea of the present invention is not limited thereto, and the shape of the receptacle connector 20 may be different.

Hereinafter, a plug connector according to an embodiment of the technical idea of the present invention will be described in detail with reference to fig. 6 to 11. For convenience of explanation, parts overlapping with those explained using fig. 2 to 5 will be briefly explained or omitted.

Fig. 6 is a plan view showing a plug connector according to an embodiment of the present invention, fig. 7 is a plan view showing a plug terminal according to an embodiment of the present invention, fig. 8 is a sectional view taken along a-a 'of fig. 6, fig. 9 is a sectional view taken along B-B' of fig. 6, fig. 10 is a front view showing a plug connector according to an embodiment of the present invention, and fig. 11 is a front view showing a plug terminal according to an embodiment of the present invention.

Referring to fig. 6 to 11, the first plug terminal 201 includes first to

third contact portions

210, 220, 230, and the first contact portion 210 of the first plug terminal 201 may be formed on the first wall portion 110 of the mold portion 100. The first contact portion 210 may include a first plate portion 211, a first bent portion 212, a first extended portion 213, a second extended portion 214, and a first mounting portion 215.

In addition, the first wall portion 110 may include an inner side 111, an upper surface 112, an outer side 113, a lower surface 114, and two sides (not shown). Since the second wall portion 120 is opposite to the first wall portion 110 and has the same shape as the first wall portion 110, only the first wall portion 110 will be described.

The first plate portion 211 of the first contact portion 210 may be elongated in the third direction Z and formed on the inner side surface 111 of the first wall portion 110. Therefore, the first plate portion 211 can protect the inner surface 111 of the first wall portion 110.

The first bent portion 212 of the first contact portion 210 may be formed in the following manner: is connected to one side of the first plate portion 211 and is bent and elongated in the second direction Y, and surrounds the upper surface of the first wall portion 110. For example, the first bent portion 212 is bent to surround the upper surface of the first wall portion 110 in the second direction Y, and therefore the first bent portion 212 can protect the upper surface 112 of the first wall portion 110.

The first extension portion 213 of the first contact portion 210 is connected to the first bent portion 212, extends in the third direction Z, and is guided by sliding contact during fitting with a mating connector, so that the first extension portion 213 can protect the outer side surface 113 of the first wall portion 110.

The second extending portion 214 of the first contact portion 210 is connected to the other side of the first plate portion 211, is bent and extended along the second direction Y, and may be formed on the lower surface 114 of the first wall portion 110.

At this time, the second extension portion 214 may be formed through the lower portion of the mold portion 100, and thus the second extension portion 214 may protect the lower portion of the first wall portion 110.

The first mounting portion 215 of the first contact portion 210 may be in a shape protruding from the second extension portion 214, and the first mounting portion 215 may be exposed from a lower portion of the first wall portion 110. That is, the first mounting portion 215 may protrude from the lower surface of the mold portion 100 to be exposed at a prescribed interval, and the first mounting portion 215 may mount the plug connector 10 on a substrate (not shown) using a method such as soldering.

The length of the first contact portion 210 is formed to be longer than the interval between the second contact portion 220 and the third contact portion 230, and when combined with the mating connector, the length of the first contact portion 210 in the first direction X is increased, thereby increasing the area of the entire contact portion.

In addition, with respect to the first contact portion 210 and the second contact portion 220 located in the vertical direction, one side end of the first contact portion 210 may form an overlapping region 310 overlapping with the second contact portion 220 on the second direction Y extension line, and the other side end of the first contact portion 210 may form an overlapping region 320 overlapping with the third contact portion 230 on the second direction Y extension line.

In addition, the second plug terminal 202, which is opposed to the first plug terminal 201 and has the same shape, may also form the overlapping

regions

330, 340.

Since the second plug terminal 202 faces the first plug terminal 201 and has the same shape, only the first plug terminal 201 will be described.

Thus, when the first contact portion 210 receives an external force in the second direction Y when being coupled with the mating connector, not only the first contact portion 210 resists the external force, but the second contact portion 220 and the third contact portion 230 connected by the first connection portion 218 and the second connection portion 219 on both sides of the first contact portion 210 can be supported by the overlapping

regions

310 and 320 against the external force, and the first contact portion 210 can strongly support each other against the external force applied in the second direction Y.

Therefore, in the case of a contact-mating connector, the mold section and the plug terminal can be strongly supported by each other by a force acting from the outside.

In addition, in the case of fitting (contacting) with the mating connector, the inclined surface 115 may be formed on one side of the first plate portion 211 to support against an external force acting on the plug connector 10 in the second direction Y at the first extended portion 213.

As shown in fig. 8, since the inclined surface 115 is formed such that the width thereof gradually increases from the upper surface 112 of the first wall portion 110 in the depth direction, that is, in the direction in which the mating connector enters, the sectional width of the inclined surface 115 can be formed such that the lower side thereof increases more than the upper side thereof, so that the strength of the mold portion 100 can be enhanced and the coupling with the mating connector can be easily performed.

The inclined surface 115 is preferably formed from a portion where the first plate portion 211 and the first bent portion 212 are connected to the upper surface of the base portion 101, but is not limited thereto.

That is, since the first plate portion 211 of the first plug terminal 201 is formed and supported on the inner surface 111 of the first wall portion 110 and the inclined surface 115 is formed on one side of the first plate portion 211, the mold portion and the plug terminal can be strongly supported by a force applied from the outside when the mating connector is fitted.

The first contact portion 210 of the first plug terminal 201 may connect the second contact portion 220 and the third contact portion 230 together at both sides in the second direction Y through the connection portion, and the second contact portion 220 includes a second plate portion 221, a second bent portion 222, a third extended portion 223, a first bent portion 224, and a second mounting portion 225. The third contact portion 230 includes a third plate portion 231, a third bent portion 232, a fourth extended portion 233, a second bent portion 234, and a third mounting portion 235.

Since the third contact portion 230 is opposite to the second contact portion 220 and has the same shape, only the second contact portion 220 will be described.

Specifically, as shown in fig. 9 to 11, the second contact portion 220 may be formed as follows: connected to the first contact portion 210 and connected to one side surface of the first wall portion 110 and one side surface of the third wall portion 130.

The second plate portion 221 of the second contact portion 220 may be formed on the outer side surface side of the third wall portion 130, and therefore, the second plate portion 221 may protect the outer side surface side of the third wall portion 130. The second bent portion 222 of the second contact portion 220 may be formed in the following manner: the side connected to the second plate portion 221 is bent and extended in the first direction X and surrounds the upper surface side of the third wall portion 130, and thus, the second bent portion 222 may protect the upper surface side of the third wall portion 130.

The third extending portion 223 of the second contact portion is connected to the other side of the second bent portion 222, extends in the third direction Z, and is guided by sliding contact during fitting with the mating connector, so that the third extending portion 223 can protect the inner side surface side of the third wall portion 130.

The first bent portion 224 of the second contact portion is connected to the other side of the second plate portion 221, and is connected to the second mounting portion 225, and the first bent portion 224 can adjust the position of connection to the second mounting portion 225.

The second mounting portion 225 may be in a shape protruding from the first bent portion 224, and may be exposed from a lower portion of the third wall portion 130. That is, the second mounting portion 225 may protrude from the lower surface of the mold portion 100 to be exposed at a prescribed interval, and the second mounting portion 225 may mount the plug connector 10 on a substrate (not shown) using a method such as soldering.

In addition, the supporting portion 135 may be formed to protrude from the first wall portion 110 of the mold part 100 at an upper side of the second mounting portion 225, and the supporting portion 135 is formed in a form of surrounding a portion of the upper side of the second mounting portion 225, and a lower side is formed in an open form, so that the plug connector 10 may be more firmly supported when the plug connector 10 is mounted on the substrate.

Therefore, the second contact portion 220 may protect the side surface of the first wall portion 110 and the side surface of the third wall portion 130.

In addition, a coupling portion 229 may be protrusively formed on an outer circumferential surface of the second contact portion 220 to reinforce a coupling force with the mating connector. For example, when the plug connector 10 is combined with a mating connector to form an electrical connector assembly, the combining portions 229 may be fastened to combining grooves formed at the mating connector to reinforce the combining force of the assembly of the electrical connector.

In addition, the second mounting portion 225 of the second contact portion 220 may have a shape protruding from a plane where the second plate portion 221 is formed, and the second mounting portion 225 may protrude from the plane where the second plate portion 221 is formed, be supported in a manner that the supporting portion 135 surrounds an upper surface of the protruding second mounting portion 225, and protrude at a predetermined interval from a portion where the supporting portion 135 is formed.

Therefore, the first plug terminal 201 can enlarge the area of the mounting portion (as a portion connected to the substrate) by a method such as soldering, so that the plug connector 10 can be mounted on the substrate more firmly.

The third mounting portion 235 of the third contact portion 230 may have a shape protruding from a plane where the third plate portion 231 is formed, and the third mounting portion 235 may protrude from the plane where the third plate portion 231 is formed, be supported in a manner that the supporting portion 145 surrounds an upper surface of the protruding third mounting portion 235, and protrude at a predetermined interval from a portion where the supporting portion 145 is formed.

In addition, a fastening portion 203a may be formed at the third plug terminal 203 to be fastened and fixed with the mating connector, and an engaging portion 203b may be formed in an inclined form at the fastening portion 203a to be easily coupled and separated with the mating connector.

In addition, the mounting portion 203c of the third plug terminal 203 may be protrudingly formed and may be exposed from a lower portion of the third wall portion 130. That is, the mounting portion 203c may be protruded and exposed from the lower surface of the mold portion 100, and the mounting portion of the third plug terminal may mount the plug connector 10 on a substrate (not shown) using a method such as soldering, and the supporting portion 136 may be formed to protrude from the third wall portion 130 to one side at an upper side of the mounting portion 203c of the third plug terminal 203, and the supporting portion 136 is formed in a form of surrounding a portion of the upper side of the mounting portion 203c of the third plug terminal 203, and a lower side is formed in an open form, so that the plug connector 10 may be more firmly supported when the plug connector 10 is mounted on the substrate.

In addition, the fourth plug terminal 204 is opposite to the third plug terminal 203 and has the same shape.

In addition, the interval of the overlapping region 310 where the first contact portion 210 and the second contact portion 220 overlap may be formed to be the same as the width of the third extension portion 223, and the interval of the overlapping region 320 where the first contact portion 210 and the third contact portion 230 overlap may be formed to be the same as the width of the fourth extension portion 233, but is not limited thereto, and the interval of the overlapping region may be formed to be wider or narrower.

Therefore, the plug connector according to the embodiment of the technical idea of the present invention ensures the additional supporting section using the overlapping region of the plug terminal and the additional supporting section like the inclined surface in the mold part by the above-mentioned configuration, thereby enhancing the strength of the plug connector against the external force applied to the plug connector.

In addition, the following effects are provided: the plug terminal and the mold part of the connector are mutually strongly supported and protected from multiple surfaces, the plug connector is prevented from being worn or damaged by external force, and the plug connector can be guided when the connector is in sliding contact and embedded with a mating connector, so that the metal of the mating connector terminal is in metal-to-metal contact, and the wear resistance is improved.

Although the embodiments of the present invention have been described with reference to the above drawings, the present invention is not limited to the embodiments, but may be manufactured in various forms different from each other, and those having ordinary knowledge in the art to which the present invention pertains may understand that the present invention may be implemented in other specific forms without changing the technical idea or essential features of the present invention. It is therefore to be understood that the above-described embodiments are illustrative only and not restrictive in all respects.
