This invention relates to a connector socket, and more particularly, relates to a connector socket capable of providing good engagement and positioning for a first plug and a second plug with different widths.
Since electronic products were presented to the public and as the society develops and progresses, the electronic products develop toward being light, thin, small, and portable at a quicker speed under the development tendency of technique. Inthe industry, ports of various peripheral apparatuses are commonly integrated into a connector socket. The various peripheral apparatuses could be connected to a computer through the single connector socket. Especially, ports of two plugs withdifferent widths are integrated into a connector socket. Because of the different widths of the engagement portions of the plugs, disposition of an elastic device usually realizes a good engagement between the plugs and the socket. However, under theeffect of the magnitude of the loading and other factors during the engagement, it is inevitable for the elastic device to be beyond the elastic limit to be distorted and deformed, which affects the engagement effect.
There is a connector socket currently. Please refer to FIG. 1. The connector socket includes a casing A0, a body B0 accommodated in the casing A0, and a plurality of terminals B1 disposed therein. The casing A0 is hollow and forms aaccommodating room C0 inside. The accommodating room C0 has an opening C1. The casing A0 includes a limit spring sheet A1 formed by cutting the casing A0 and protruding axially at the edge of the opening C1.
The connector socket is used for engaging with a display port ("DP" for short hereinafter) plug D0 and a high definition multimedia interface ("HDMI" for short hereinafter) plug E0. The DP plug D0 includes a first engagement part D1. The HDMIplug E0 includes a second engagement part E1. The width of the first engagement part D1 is wider than that of the second engagement part E1. When the first engagement part D1 is inserted into the accommodating room C0 of the connector socket, twosidewalls of the first engagement part D1 closely touch two sidewalls of the casing A0, and the limit spring sheet A1 stops the top surface of the first engagement part D1, so that the DP plug D0 could be positioned inside the connector socket. When thesecond engagement part E1 is inserted into the accommodating room C0 of the connector socket, a sidewall of the second engagement part E1 closely touches one of the two sidewalls of the casing A0, another sidewall of the second engagement part E1 leansagainst the limit spring sheet A1, so that the HDMI plug E0 could be positioned inside the connector socket.
The disadvantages of the connector socket are as follows:
1. When the DP plug is inserted into the accommodating room of the casing, the two sidewalls of the first engagement part touch closely the two sidewalls of the casing, and the limit spring sheet stops the top surface of the first engagementpart and is movable upwards. When the first engagement part is inserted aslant or the limit spring sheet is stirred excessively by users, because there is no stop structure above the limit spring sheet for stopping it, it is easy for the limit springsheet to be deflected exceedingly upwards or deformed seriously to lose the limit function.
2. When the HDMI plug is inserted into the accommodating room of the casing, one of the two sidewalls of the second engagement part touches closely one of the two sidewalls of the casing, the other sidewall of the second engagement part leansagainst the limit spring sheet, and because the width of the second engagement part is narrower than that of the opening, the limit spring sheet could move toward a neighbor sidewall of the casing, and there is no stop structure to stop it. When thesecond engagement part is inserted aslant, the limit spring sheet is loaded with larger force so that the limit spring sheet is excessively deflected or seriously deformed toward the neighbor sidewall of the casing to lose the limit function.
Therefore, there is a need to design a new connector socket to solve the above disadvantages.
A purpose of the invention is to provide a connector socket, which could prevent or avoid excessive deformation of a elastic device by the effect of stopping and leaning-against of a metal casing so that two plugs with different widths could beengaged with the connector socket well.
To achieve the above purpose, the connector socket of the invention adopts the following scheme:
A connector socket, for engaging with a first plug and a second plug with different widths, includes an insulation base, a metal casing, and an elastic device. The metal casing embraces the insulation base. A first engagement space and a secondengagement space being defined. The first plug occupies the first engagement space after entering the metal casing. The second plug occupies the first engagement space and the second engagement space after entering the metal casing. The elastic deviceincludes a mounted part and a leaning part. The mounted part is mounted in the insulation base. The leaning part extends form the mounted part into the second engagement space. A top sidewall of the metal casing stops the leaning part when the leaningpart moves upwards to a certain position. When the first plug enters the first engagement space, the leaning part leans against a side of the first plug close to the second engagement space. When the second plug enters the first engagement space andthe second engagement space, the leaning part leans against a top surface of the second plug.
Compared with the prior art, the elastic device is mounted in the insulation base. When the first plug enters the first engagement space, the side of the first plug close to the second engagement space presses the elastic device to move to aproper position, and the metal casing stops the elastic device for preventing or avoiding that the elastic device exceeds the elastic limit thereof to be deformed. When the second plug enters the first engagement space and the second engagement space,and the leaning part moves upwards to a certain position, the top sidewall of the metal casing stops the leaning part for preventing or avoiding that the elastic device exceeds the elastic limit thereof to be deformed.
By the effect of stopping and leaning-against of the metal casing to the elastic device at two directions, the deformation over the elastic limit of the elastic device is prevented or avoided so that the two plugs with different widths could beengaged with the connector socket well so as to enhance the engagement effect.

The fool-proof device 13 is a long column for a preferred embodiment and has an obliquesurface 131 formed at the side of the fool-proof device 13 toward the tongue plate 12.
Please refer to FIGS. 2, 3 and 4. The metal casing 20 is hollow and has a top sidewall 21 and a bottom sidewall 22 disposed oppositely, a left sidewall 23 and a right sidewall 24 disposed oppositely, and several fixing sheets 231, 241 extendingdownwards from the left sidewall 23 and the right sidewall 24 respectively and mounted on a circuit board. The top sidewall 21, the bottom sidewall 22, the left sidewall 23, and the right sidewall 24 together form an accommodating space. Theaccommodating space has an opening 25. The top sidewall 21 and the bottom sidewall 22 are respectively pressed to form two pressing parts 211, 221 protruding into the accommodating space. The left sidewall 23 is bent to form a stop part 232 at theopening 25. The right sidewall 24 is cut to form an elastic locking part 242 toward the left sidewall 23. The metal casing 20 has a raised portion 212 upward disposed at the top sidewall 21 near the left sidewall 23. The raised portion 212 is used foraccommodating the protrusion 14. The insulation base 10 is sleeved into the accommodating space. The insulation base 10 is fitted closely with the circumference of the metal casing 20.
The terminals 30 are positioned in the base portion 11 first and extend into the tongue plate 12.
An end of the positioning part 40 is mounted in the insulation base 10, and another end thereof extends from the blind hole 15 of the base portion 11 into the accommodating space. The positioning part 40 has a leaning surface 41 at the end ofthe positioning part 40 into the accommodating space.
The elastic device 50 includes a mounted part 51 mounted in the insulation base 10 and a leaning part 52. The leaning part 52 is formed to be a curve part by bending downwards from the mounted part 51. The mounted part 51 is mounted in thepositioning slot 141. A tail end of the leaning part 52 has a width portion 53 leaning against the left sidewall 23. However, in other embodiments, the leaning part 52 could be without the width portion 53. The elastic device 50 is inserted in thepositioning slot 141 in the protrusion 14, so that the mounted part 51 is mounted in the positioning slot 141 and the leaning part 52 extends into the accommodating space.
The shield sheet 60 is disposed at the rear end of the insulation base 10 and locks with the metal casing 20.
Please refer to FIGS. 5-10. For operation, the connector socket is used for engaging with a first plug and a second plug with different widths. In this embodiment, the first plug is a high definition multimedia interface ("HDMI" for shorthereinafter) plug 70. The second plug is a display port ("DP" for short hereinafter) plug 80. The HDMI plug 70 and the DP plug 80 includes a first engagement part 71 and a second engagement 81 respectively. The width of the first engagement part 71 isnarrower than that of the second engagement part 81.
When the HDMI plug 70 slides into the accommodating space, a first engagement space 111 is defined and occupied by the HDMI plug 70. The tongue plate 12 is capable of being engaged with a first engagement hole 72 of the first engagement 71. Thewidth portion 53 leans against the left sidewall 23. Because the outer size of the first engagement part 71 is smaller than the hole size of the opening 25, a side of the elastic device 50 leans against the left sidewall of the first engagement part 71to prevent the movement of the first engagement part 71 toward the elastic device 50 for sure that the first engagement part 71 is positioned well in the accommodating space of the metal casing 20. At this moment, the HDMI plug 70 is engaged with theconnector socket more tightly under the limit effect by the positioning part 40 lying at the recess portion 73 with the leaning surface 41 of the positioning part 40 corresponding to the outer surface of the first engagement part 71, and the pressingparts 211, 221 and the locking part 242 coordinating with the positioning part 40 and the elastic device 50.
When the DP plug 80 slides into the accommodating space, a second engagement space 222 is defined and occupied together with the first engagement space 111 by the DP plug 80. The tongue plate 12 enters a second engagement hole 82 of the secondengagement part 81. The oblique surface 131 leans against an oblique portion 84. At this moment, the positioning part 40 is inserted into a sunken accommodating slot 83. The terminals 30 on the tongue plate 12 and terminals disposed in the secondengagement hole 82 contact and connect each other. The stop part 232 limits the DP plug 80 for preventing excessive shift thereof. The leaning part 52 leans against the top surface of the second engagement part 81. When the leaning part 52 movesupwards to a certain position, the raised portion 212 stops the leaning part 52. Under the limit effect by the pressing parts 211, 221 and the locking part 242 coordinating with the positioning part 40 and elastic device 50, the DP plug 80 is engagedwith the connector socket more tightly, which improves the engagement.
As discussed above, the connector socket of the invention has the following advantages:
1. The HDMI plug is inserted into the first engagement space. A sidewall of the HDMI plug touches closely the right sidewall of the metal casing, and another sidewall thereof leans against the elastic device. The width of the first engagementpart is smaller than the hole size of the opening. The elastic device could move toward the adjacent left sidewall of the metal casing. Because the elastic device is disposed in the insulation base, when the first engagement part is engaged aslant orthe elastic device is stirred excessively by users, the leaning part would be stopped by the sidewall of the metal casing for preventing or avoiding the excessive deflection or serious deformation on the elastic device to affect the limit function andthe engagement.
2. The DP plug is inserted into the first engagement space and the second engagement space. When the second engagement part is engaged aslant or the elastic device is stirred excessively by users, because there is a stop structure, the raisedportion, above the elastic device stopping the elastic device, the excessive deflection upwards or serious deformation could be prevented or avoided so as to maintain the limit function and improve the engagement.
3. When the HDMI plug is inserted into the first engagement space, the positioning part lies at the recess portion with the leaning surface of the positioning part corresponding to the outer surface of the first engagement part. Thereby,further coordinating with the pressing parts and the locking part of the metal casing, the HDMI plug is engaged with the connector socket more tightly and the engagement is more firm.
4. There is the stop part disposed at the front of the sidewall of the metal casing near the elastic device. When the DP plug is inserted into the first engagement space and the second engagement space, the leaning part of the elastic deviceleans against the top surface of the second engagement part. At this moment, the stop part stops the elastic device from inclining.
With the example and explanations above, the features and spirits of the invention will be hopefully well described. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made whileretaining the features and spirits of the invention.
