DETAILED DESCRIPTION

The following will describe the contact type connector (hereinafter sometimes referred to as "connector") of the embodiment of the present invention with reference to the accompanying drawings. In each of the drawings, the same elements or elements having the same function are marked with the same reference numerals. The drawings are not drawn to scale.

In the following, the contact type connector of the present invention is specifically implemented in the form of a USB 3.2 Gen2 A-type socket connector. It should be understood that the contact type connector of the present invention is backward compatible with the specifications of USB 3.1/3.0/2.0/1.1, and can also be specifically implemented in the form of a USB 3.1/3.0/2.0/1.1 socket connector. The contact type connector of the present invention is not limited to the USB 3.2 Gen2 A-type socket connector, but can be applied to other types of connectors. Because the definition of the pin position and its specification of the USB 3.2 Gen2 socket connector are not the focus of the present invention and can be obtained from other published documents, their description is omitted.

FIG. 1 is a perspective view of a contact type connector according to a first embodiment of the present invention, FIG. 2 is another perspective view of a contact type connector according to the first embodiment of the present invention, and FIG. 3 is a perspective exploded view of a contact type connector according to the first embodiment of the present invention. Referring to FIG. 1 to FIG. 3, the main components of the contact type connector according to the first embodiment of the present invention are described, and the contact type connector as a whole is marked with a component symbol 10. The contact type connector 10 includes an insulating housing 11, a conductive shell 12, an insulating rear cover 13, a plurality of contacts 14, and a metal accessory 15.

The contact type connector 10 is used to electrically connect a mating connector as a first connection object and a wiring substrate as a second connection object. The mating connector (not shown in the drawings) is assembled to the contact type connector 10 in a first direction D1. In other words, the first direction is parallel to the assembly direction of the mating connector. A plurality of contacts 14 are arranged in a second direction D2 perpendicular to the first direction D1 and are held by the insulating housing 11. The insulating rear cover 13 has a plurality of positioning slots for limiting and separating the plurality of contacts 14 from each other.

FIG. 4 is a partial cross-sectional side view of the contact type connector according to the first embodiment of the utility model, and FIG. 5 is a cross-sectional side view of the contact type connector according to the first embodiment of the utility model. As shown in FIG. 4 and FIG. 5, the conductive housing 12 is fixed to the insulating rear cover 13, and a part of the contact member 14 is exposed from the insulating rear cover 13 so as to contact the wiring substrate. The details of each element will be described below.

The insulating rear cover 13 has a contact protection portion 131, and the contact protection portion 131 is adjacent to the mounting surface of the contact type connector 10. The contact protection portion 131 shields at least a portion of the contact 14 when viewed from the second direction D2.

Fig. 6 is a perspective view of the conductive housing 12. The configuration of the conductive housing 12 will be described with reference to Fig. 6. The conductive housing 12 is made by punching and bending a metal sheet. The conductive housing 12 defines a space for accommodating a mating connector.

Two upper contact arms 125 are formed on the upper surface of the conductive housing 12, and two lower contact arms 126 are formed on the lower surface of the conductive housing 12. A side contact arm 127 is formed on each of the two side surfaces of the conductive housing 12. When the mating connector is assembled to the contact type connector, these contact arms will contact the metal housing of the mating connector. Generally speaking, these contact arms are provided for the purpose of grounding connection or increasing the holding force of the mating connector.

The conductive housing 12 is formed with a plurality of retaining portions 121. Each retaining portion 121 extends from the rear edge of the side of the conductive housing 12 in the first direction and is inserted into a corresponding retaining hole formed in the insulating rear cover 13 in an interference fit manner. A protrusion 122 in the shape of a racetrack or an oblong is formed at the base of each retaining portion 121 to increase the interference of the conductive housing 12 with the insulating rear cover 13 and improve the resistance to pulling the conductive housing 12 out of the insulating rear cover 13.

In order to firmly clamp the insulating shell, the conductive shell 12 is formed with a first stopper 123 and two second stoppers 124 at the rear edge of the upper surface and the rear edge of the lower surface. A portion of the rear edge of the upper and lower surfaces of the shell is torn and deflected inward by stamping, thereby forming the first stopper 123 and the second stopper 124 which are concave inward.

FIG. 7 is a perspective view of the insulating housing 11. The structure of the insulating housing 11 will be described with reference to FIG. 7. The insulating housing 11 is made of a resin material or a polymer material by injection molding. Preferably, the insulating housing 11 and the contact 14 are integrally formed by insert molding. In this way, the operation procedure of assembling the contact can be saved.

The insulating housing 11 has a main body 110 and an extension (i.e., tongue) 111. The extension 111 extends from the main body 110 in a first direction D1. The conductive housing 12 surrounds the extension 111 of the insulating housing 11. The insulating housing 11 is formed with a first recess 1101 at the upper edge of the main body 110, and two second recesses 1102 at the lower edge of the main body 110. The first stopper 123 and the second stopper 124 of the conductive housing 12 are respectively tightly received in the first recess 1101 and the second recess 1102 correspondingly formed in the main body 110 of the insulating housing 11. By the first stopper 123 and the second stopper 124 abutting against the first recess 1101 and the second recess 1102, the clamping range of the insulating housing 11 can be expanded, so that the insulating housing 11 is firmly held relative to the conductive housing 12 or the insulating back cover 13, and the insulating housing 11 is prevented from shaking (swinging) up and down or shaking (swinging) left and right.

FIG8 is a side view of the contact 14. The structure of the contact 14 will be described with reference to FIG8. It should be understood that the contact provided by the contact-type connector according to the present invention is not limited to a single type of contact. For the convenience of describing the contents of the present invention, only a single type of contact 14 is described. It does not mean that the connector has only a single type of contact. Depending on the requirements, a portion of the contact may be made into a different shape from another portion of the contact, but in principle, the portion of the contact on the wiring substrate side is made into the same shape.

The contact 14 is made of a conductive material (e.g., copper or copper alloy). The contact 14 has a first contact portion 140 for contacting a mating connector, a first elastic arm 141, a holding portion 142 held by an insulating housing, and a second contact portion 145 for contacting a wiring substrate. The first contact portion 140 forms the first elastic arm 141 and is positioned at the extension portion 111 of the insulating housing 11. The first elastic arm 141 extends from the holding portion 142. The second contact portion 145 is opposite to the first contact portion 140 and extends out of the body portion 110 of the insulating housing 11.

The contact member 14 further includes a second elastic arm 143 extending from the main body 110 of the insulating housing 11, a bent portion 144, and a terminal portion 146 extending from the second contact portion 145. The second contact portion 145 is connected to the second elastic arm 143 through the bent portion 144. The second elastic arm 143 and the bent portion 144 of the contact member 14 can act as a spring portion to provide a resisting elastic force when the wiring substrate pushes the second contact portion 145 in the first direction D1.

The end portion 146 abuts against the inner surface of the insulating rear cover 13, so that the end portion 146 of the contact 14 is positioned inside the insulating rear cover 13 and is uniformly limited. As a result, a uniform exposure degree of the second contact portion 145 can be obtained. In addition, by abutting the end portion 146 against the inner surface of the insulating rear cover 13, the part of the contact on the wiring substrate side can be pre-pressed to increase the contact force when the second contact portion 145 contacts the wiring substrate.

The second elastic arm 143 extends approximately in the third direction D3 toward the mounting surface of the contact type connector, but is not limited thereto. The second contact portion 145 is approximately linear and is positioned parallel to a plane formed by the first direction D1 and the third direction D3, wherein the third direction D3 is perpendicular to the first direction D1 and the second direction D2. Although the second contact portion 145 can be parallel to the third direction D3, before the second contact portion 145 contacts the wiring substrate, it is preferred that the second contact portion 145 be tilted at an inclination angle θ relative to the third direction D3 (i.e., the vertical direction), and the inclination angle θ is preferably less than 3 degrees, more preferably less than 10 degrees, and particularly preferably less than 20 degrees. In this way, it can be ensured that there is sufficient contact force when the second contact portion 145 contacts the wiring substrate. Therefore, it is preferred to tilt the second contact portion 145 relative to the third direction D3.

The bent portion 144 of the contact 14 and a portion of the second contact portion 145 are shielded by the contact protection portion 131, and the portion of the second contact portion 145 is adjacent to the bent portion 144. Since the bent portion 144 and its adjacent portions are more easily deformed by external forces, in order to prevent the wiring substrate from colliding with the bent portion 144 and its adjacent portions when installing the contact type connector or installing the wiring substrate, the contact protection portion 131 adjacent to the mounting surface of the contact type connector 10 is formed in the insulating rear cover 13.

FIG9 is a perspective view of a metal fitting of a contact-type connector according to the first embodiment of the utility model. The composition of the metal fitting 15 will be described with reference to FIG9. The metal fitting 15 is fixed to the lower surface of the conductive housing 12 by welding, such as laser welding, but is not limited thereto. If necessary, the metal fitting may also be fixed to the upper surface of the conductive housing 12.

The metal fitting 15 has a main body 150 to be welded to the lower surface of the conductive housing 12 and a pair of flanges 151 parallel to the mounting surface of the contact type connector, and each flange 151 is formed with a through hole 152 for the rod of a screw or bolt as a fastening means to pass through so as to lock the metal fitting 15 on the base. If necessary, a positioning hole can be formed in the flange 151 so as to accurately place the contact type connector at a specified position before locking the metal fitting 15 on the base.

Fig. 10 is a perspective view of a contact type connector according to a second embodiment of the present invention. In the second embodiment, the same component numbers as those in the first embodiment are assigned to the parts common to the first embodiment and their descriptions are omitted. The main difference from the first embodiment is that the contact type connector of the second embodiment further includes an insulating member 11A.

Figure 11 is another perspective view of the contact type connector according to the second embodiment of the present invention. In order to clearly show the internal details, the conductive housing, metal accessories and insulating rear cover are not shown. Figure 12 is a cross-sectional side view of the contact type connector according to the second embodiment of the present invention.

Compared with the first embodiment, the contact type connector 10 of the second embodiment further includes an insulating member 11A. The insulating member 11A is generally an elongated member extending along the second direction D2. The insulating member 11A is formed together when the insulating housing 11 is formed by insert injection molding, so that the insulating member 11A is integrally formed with the terminal portion of the contact 14 by insert injection molding. Therefore, the insulating member 11A is formed with the same material as the insulating housing 11. With the insulating member 11A, the terminal portion of the contact 14 is forcibly confined in the insulating rear cover 13 and is positioned consistently, so that the second contact portion of the contact 14 can be neatly and consistently positioned.

FIG13 is a schematic diagram of the contact type connector according to the present invention when it is actually used. The contact type connector is installed inside the electric machine. In the figure, the housing of the electronic machine is partially shown, and the housing of the electronic machine is marked with the element symbol 30. The wiring substrate as the second connection object is marked with the element symbol 20.

The housing 30 is formed with an opening 31, and the contact type connector 10 is configured such that the conductive housing 12 is embedded in the opening 31, so that the connection hole of the contact type connector 10 is exposed to the housing 30. The wiring substrate 20 is formed with a plurality of electrodes 21 at the edge portion, and these electrodes 21 are in conductive contact with the contact pieces 14 of the contact type connector 10.

Because the contact 14 of the contact type connector 10 is not fixed to the wiring substrate by welding as in the conventional method, the height of the wiring substrate can be varied within a certain range. Therefore, there is no need to strictly require the relative position of the opening on the housing and the wiring substrate.

Although the present invention is described with reference to the preferred embodiments, it should be understood that within the scope of the invention and the scope of the present invention, many changes and modifications are possible for those with ordinary technical knowledge in the technical field to which the present invention belongs. Therefore, the present invention is not limited to the disclosed embodiments, but is subject to the text of the claims, that is, equivalent changes and modifications made without departing from the claims of the present invention should still fall within the scope of the present invention.
