Description

Technical Field

[0001] The present invention relates to an electrical connector. Background Art

[0002] Existing electrical connectors, especially board-to-board connectors, are often used to connect different circuit boards. For example, a socket connector and a plug connector are respectively installed on different circuit boards to connect the circuit boards to each other. The size of the electrical connectors on mobile devices such as smart phones is very small, resulting in a reduction in the structural strength and durability of each connector.

[0003] Furthermore, board-to-board connectors come with different numbers of terminals depending on the usage specifications. Therefore, insulators of different sizes need to be designed for different specifications, and the corresponding number of terminals are embedded therein. In this way, production designers are bound to produce molds of various sizes in order to produce insulators to cope with different numbers of elastic terminals, which can easily complicate the products and production line equipment, and also cause confusion and difficulty in management.

At the same time, rectangular coordinates X - Y - Z are provided to facilitate the subsequent description and reference of related components. Please also refer to Figure 1A and Figure 1B , in this embodiment, the electrical connector 100A, for example, is a board - to - board connector, which includes a plurality of first structures 110 and a plurality of elastic terminals 120. The first structure 110 has electrical insulation. Each first structure 110 has a first assembly part 111 and a second assembly part 112. The elastic terminals 120 are assembled to the first structure 110, and the first structure 110 and at least one elastic terminal 120 that are assembled corresponding to each other form a basic unit, so that the electrical connector 100A includes at least one basic unit. Here, one first structure 110 is paired with two elastic terminals 120 as a basic unit, and the electrical connector 100A in this embodiment is composed of two basic units.

[0047] Furthermore, adjacent first structures 110 are assembled to each other by a first assembling portion 111 and a second assembling portion 112, so that the elastic terminals 120 are arranged on the X-Y plane along the axial direction (Y axis in this embodiment). As Figure 1B shown, each elastic terminal 120 has a coupling portion 121 and a contact portion 122 (taking one of the elastic terminals 120 as an example here). The coupling portion 121 is assembled to the first structure 110 and located on the X-Y plane, and the contact portion 122 extends from the coupling portion 121 and hangs above the coupling portion 121. In this embodiment, there are multiple elastic terminals 120 on each first structure 110, and on the same first structure 110, the coupling portions 121 of the elastic terminals 120 are inserted into the first structure 110 in opposite directions. Here, the first structure 110 has two slots 113 facing in opposite directions and presents an S shape, so that the coupling portions 121 of the elastic terminals 120 can be inserted into the two concave contours of the S shape, and then after assembly, the contact portions 122 protrude above the first structure 110 and are arranged in a staggered manner in opposite directions on the X-Y plane, as Figure 1A shown.

[0048] Furthermore, a first assembling portion 111 and a second assembling portion 112 are respectively present on opposite side surfaces S1 and S2 of each first structure 110. Here, it is taken as an example that the first assembling portion 111 is located on the side surface S1 and the second assembling portion 112 is located on the side surface S2. The first assembling portion 111 and the second assembling portion 112 are structurally adapted. For example, Figure 1B shown, the first assembling portion 111 is a concave hole, and the second assembling portion 112 is a convex post, so that the first structures 110 are spliced with each other through the side surfaces S1 and S2 and are located on the X-Y plane. As Figure 1A shown, the first assembling portion 111 and the second assembling portion 112 on the side surfaces S1 and S2 are in contact with each other, and the contact direction is parallel to the X-Y plane.

[0049] As Figure 1A and Figure 1B shown, the first structure 110, which is the basic unit of the electrical connector 100A, has a first assembling portion 111 and a second assembling portion 112 with structurally adapted to each other on its opposite side surfaces S1 and S2. Therefore, users can increase or decrease them according to the specification requirements. Figure 1C is a schematic diagram of an electrical connector according to another embodiment of the present invention. Please refer to Figure 1C , which is an electrical connector 100B formed by arranging and assembling four basic units along the Y axis. The first structure 110 and the elastic terminals 120 thereon are the same as those in the foregoing embodiment, and here they are arranged along the Y axis and present a staggered state in opposite directions. In view of the above embodiment, users can continuously arrange and combine them in the manner of the above embodiment according to their needs.

[0050] Figure 2A is a schematic diagram of an electrical connector according to another embodiment of the present invention. Figure 2B Drawing from another perspective Figure 2A Please also refer to Figure 2A and Figure 2B In this embodiment, in addition to the first structure 110 and the elastic terminal 120 of the above embodiment, the electrical connector 100C further includes a second structure 130, which is assembled to the first structure 110 to at least partially surround and limit the first structure 110 on the XY plane, wherein the first structure 110 and the elastic terminal 120 are the same as those described above and are not described in detail. The second structure 130 of this embodiment is, for example, a frame, which is used to abut against the side surface of the ring formed by assembling the two first structures 110. Figure 2C and Figure 2D They are Figure 2A The electrical connector is shown in exploded view from different angles. Please also refer to Figure 2A , Figure 2C and Figure 2D In this embodiment, the second structure 130 has a plurality of first limiting protrusions 131 and 132 located on its inner wall, and the first structure 110 will form a plurality of limiting recesses R1 located on the side of the ring after being assembled, and the first limiting protrusions 131 and 132 correspondingly abut against the limiting recesses R1. Accordingly, the second structure 130 abuts against the side of the ring formed by the first structure 110 through its inner wall, and the first limiting protrusions 131 and 132 located on the inner wall correspondingly abut against the limiting recesses R1, so that the second structure 130 can achieve the effect of clamping the first structure 110 in one place, and the first structure 110 can be kept on the XY plane. Here, the mutual abutment direction of the first limiting protrusions 131 and 132 and the limiting recesses R1 is parallel to the XY plane.

[0051] Figure 3A is a schematic diagram of an electrical connector according to another embodiment of the present invention. Figure 3B and Figure 3C They are Figure 3A A schematic diagram of some components of an electrical connector. Figure 3D yes Figure 3A Please also refer to the exploded view of the electrical connector. Figures 3A to 3B In this embodiment, the electrical connector 200 includes two first structures 210, a plurality of elastic terminals 220 and a second structure 230, wherein each first structure 210 presents a U-shaped profile and has an opening recess 214, the first structures 210 are staggered and connected to each other through the opening recess 214, and the first assembly portion 215 and the second assembly portion 216 are located in the opening recess 214. Figure 3CAs shown, the end 213 of the first structure 210 is embedded in the opening recess 214, and the other end 212 abuts against the outer side surface of the first structure 210 which is the opposing member and is exposed, and thus the limiting recess R2 is formed on the circumferential side surface. Furthermore, the second structure 230 also presents a frame shape and has a plurality of first limiting protrusions 231 for abutting against the aforementioned limiting recess R2. As Figure 3B shown, the abutting direction of the first limiting protrusion 231 and the limiting recess R2 is parallel to the X-Y plane and is substantially opposite to each other along the X-axis. In other words, after the first structures 210 are butted against each other along the X-axis, the second structure 230 provides an opposing force along the X-axis to the first structure 230 through the first limiting protrusions 231 to ensure the tight bonding degree of the first structures 210. In this embodiment, the elastic terminals 220 are embedded in the slots 211 of the first structure 210 in the same direction.

[0052] In addition, in this embodiment, after the first structures 210 are butted against each other, the abutting direction of the first assembly portion 215 and the second assembly portion 216 is substantially along the Z-axis (orthogonal to the X-Y plane), so as to provide a constraining force in the Z-axis direction in addition to the above-mentioned butting and the constraining force parallel to the X-Y plane applied by the second structure 230, and to achieve the effect of completely constraining the first structures 210 in three-dimensional space.

[0053] On the other hand, the second structure 230 also has a plurality of second limiting protrusions 232 located at its top, which abut against the first structure 210. The abutting direction of the second limiting protrusions 232 and the first structure 210 is along the Z-axis and is orthogonal to the X-Y plane. The second limiting protrusions 232 also abut against the first assembly portion 215 and the second assembly portion 216, and the abutting direction of the second limiting protrusions 232 and the first assembly portion 215, the second assembly portion 216 is along the X-axis and is parallel to the X-Y plane. Here, as Figure 3B and Figure 3C shown, the second limiting protrusions 232 located on the left and right sides abut against the first assembly portion 215, and the second limiting protrusions 232 located in the center have two notches 233 and abut against the second assembly portion 216.

[0054] In summary, in the above embodiment of the present invention, the electrical connector is composed of a plurality of first structures and a plurality of elastic terminals. The corresponding first structures and elastic terminals form a basic unit, and the basic unit is used as the basic component of the electrical connector, that is, the electrical connector is formed by a single basic unit or assembled together like building blocks by a plurality of basic units.

[0055] Each first structure has a first assembly part and a second assembly part. When the above combination is carried out, the first structures can be assembled together by the mutual cooperation of the first assembly part and the second assembly part. Furthermore, the elastic terminals are arranged axially on a plane to form a planar connection terminal structure for the required purpose. Moreover, in some embodiments, the assembled first structure needs to be combined with a second structure to improve its structural strength, so as to ensure that these elastic terminals on the first structure are located on the same plane and have the same height, meeting the usage requirements of the board-to-board connector.

[0056] In this way, the user can assemble different specifications of electrical connectors by means of the above combination method, thus effectively simplifying the complicated processes in the design and production processes and effectively improving the production efficiency.
