Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to an electric connector and an electronic device. Background Art

[0002] Electrical connectors are widely used in the field of electronic products due to their stable electrical performance, and TYPE-C connectors have become one of the most widely used connectors due to their many advantages such as fast transmission speed, hot plug support, and no distinction between front and back sides.

[0003] At present, the most commonly used TYPE-C connectors on the market are 16PIN and 24PIN, which are mainly used in mobile devices such as mobile phones, computers, and chargers. However, there are also many devices (such as mobile power supplies, wireless headphones, electric shavers, and electric toothbrushes) that only need Type C to provide charging function, so 6PIN electrical connectors are used.

[0004] The existing 6-pin electrical connector has an integrated design of the clamping part and the conductive terminal that are clamped with the male head and are made of copper without an independent steel sheet, which leads to rapid wear, short plug-in life, and poor plug-in feel.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0038] See also Figures 1 to 6 The electrical connector provided in the first embodiment of the present invention includes a conductive terminal 10 , a main plastic component 20 , an outer iron shell 30 , a first middle steel sheet 40 and a second middle steel sheet 50 .

[0039] The conductive terminal 10, the first middle steel sheet 40, the second middle steel sheet 50, and the main plastic part 20 form a connector body 60. Specifically, the conductive terminal 10, the main plastic part 20, the first middle steel sheet 40, and the second middle steel sheet 50 are formed into the connector body 60 by injection molding. The connector body 60 is assembled in the outer iron shell 30, for example, the connector body 60 is assembled in the outer iron shell 30 by snap-fitting.

[0040] The first middle steel sheet 40 is an integrated structure, and the second middle steel sheet 50 is an integrated structure.

[0041] The conductive terminal 10, the first middle steel sheet 40, and the second middle steel sheet 50 are arranged side by side, and the conductive terminal 10 is located between the first middle steel sheet 40 and the second middle steel sheet 50. The first middle steel sheet 40 serves as a first grounding PIN, and the second middle steel sheet 50 serves as a second grounding PIN.

[0042] The first middle steel sheet 40 is provided with a first wrapping portion 41a, and the second middle steel sheet 50 is provided with a second wrapping portion 51a. The first wrapping portion 41a and the second wrapping portion 51a are arranged opposite to each other, and the main plastic part 20 is located between the first wrapping portion 41a and the second wrapping portion 51a, that is, the main plastic part 20 is protected and limited by the first wrapping portion 41a and the second wrapping portion 51a.

[0043] Among them, after the first middle steel sheet 40 and the second middle steel sheet 50 are formed by punching and blanking a first plate, the conductive terminal 10 is formed by punching, blanking and bending a second plate. The first plate and the second plate are different plates, that is, the two middle steel sheets and the conductive terminal come from different plates, rather than being obtained from a single plate.

[0044] Specifically, in this embodiment, the first wrapping portion 41a includes a first grounding PIN first contact portion 411a located at the top, a first grounding PIN second contact portion 412a located at the bottom, and a first side portion 413a respectively connected to the first grounding PIN first contact portion 411a and the first grounding PIN second contact portion 412a, that is, there are two contact portions for grounding (the first grounding PIN first contact portion 411a and the first grounding PIN second contact portion 412a) on the first middle steel sheet 40, and the first grounding PIN first contact portion 411a, the first grounding PIN second contact portion 412a and the first side portion 413a form a U-shaped structure.

[0045] The second wrapping portion 51a includes a second grounding PIN first contact portion 511a located at the top, a second grounding PIN second contact portion 512a located at the bottom, and a second side portion 513a respectively connected to the second grounding PIN first contact portion 511a and the second grounding PIN second contact portion 512a, that is, there are two contact portions for grounding (the second grounding PIN first contact portion 511a and the second grounding PIN second contact portion 512a) on the second middle steel sheet 50, and the second grounding PIN first contact portion 511a, the second grounding PIN second contact portion 512a and the second side portion 513a form a U-shaped structure.

[0046] The first wrapping portion 41 a and the second wrapping portion 51 a of the U-shaped structure are symmetrically arranged on both sides of the main plastic component 20 , and the main plastic component 20 is wrapped in the grooves of the two U-shaped structures.

[0047] The following effects are achieved by providing the first wrapping portion 41a and the second wrapping portion 51a:

[0048] 1. In the conventional structure, the clamping parts at both ends of the conductive terminal and clamped with the male head are cross-sectional structures of the material, and their height (i.e., the thickness of the copper material) is relatively small. Therefore, during the plugging and unplugging process, it is easy to be misaligned with the male head. Once misaligned, the male head will impact the plastic part during the plugging and unplugging process, causing damage to the plastic part. In this embodiment, by providing the first side edge portion 413a and the second side edge portion 513a, it is no longer a cross-sectional structure, which can increase the height of the clamping part with the male head, and effectively avoid the problem of misalignment with the male head during the plugging and unplugging process;

[0049] 2. In the traditional structure, the clamping parts at both ends of the conductive terminal that are clamped with the male plug are cross-sectional structures of the material. Such cross-sectional structures are bound to have burrs, which will affect the contact stability with the male plug. In the present embodiment, by providing the first side edge portion 413a and the second side edge portion 513a, the surface is smoother than the cross-section, thereby enhancing the contact stability with the male plug.

[0050] In this embodiment, the conductive terminal 10 includes a first power PIN 11 , a first signal PIN 12 , a second signal PIN 13 , and a second power PIN 14 which are sequentially arranged side by side between the first middle steel sheet 40 and the second middle steel sheet 50 .

[0051] The first power PIN 11 is provided with a raised first power PIN contact portion 111, the first signal PIN 12 is provided with a raised first signal PIN contact portion 121, the second signal PIN 13 is provided with a raised second signal PIN contact portion 131, and the second power PIN 14 is provided with a raised second power PIN contact portion 141. Specifically, the first power PIN contact portion 111, the first signal PIN contact portion 121, the second signal PIN contact portion 131, and the second power PIN contact portion 141 are formed by bending.

[0052] The protruding direction of the first power PIN contact portion 111 is opposite to the protruding direction of the second power PIN contact portion 141 .

[0053] The protruding direction of the first signal PIN contact portion 121 is opposite to the protruding direction of the second signal PIN contact portion 131 .

[0054] The edge of the first middle steel sheet 40 is provided with a first grounding PIN lock portion 42, and the edge of the second middle steel sheet 50 is provided with a second grounding PIN lock portion 52. The first grounding PIN lock portion 42 and the second grounding PIN lock portion 52 are used to cooperate with the male hook to provide plugging and unplugging force.

[0055] In addition, a first grounding PIN welding foot 43 is provided at the end of the first middle steel sheet 40, a first power PIN welding foot 112 is provided at the end of the first power PIN 11, a first signal PIN welding foot 122 is provided at the end of the first signal PIN 12, a second signal PIN welding foot 132 is provided at the end of the second signal PIN 13, a second power PIN welding foot 142 is provided at the end of the second power PIN 14, and a second grounding PIN welding foot 53 is provided at the end of the second middle steel sheet 50, which are respectively used for welding.

[0056] It should be pointed out that, in a specific implementation, the first middle steel sheet 40 and the second middle steel sheet 50 can be connected together to form an integrated structure; or, the first middle steel sheet 40 and the second middle steel sheet 50 are split structures (i.e., the two are not connected together), and the present invention is not limited to this.

[0057] The above structure enables both the front and back sides of the electrical connector to have charging functions.

[0058] According to the above-mentioned electrical connector, the first middle steel sheet 40 and the second middle steel sheet 50 are respectively provided on both sides of the conductive terminal 10, and the first middle steel sheet 40 and the second middle steel sheet 50 are respectively used as the first grounding PIN and the second grounding PIN. Thus, under the premise of ensuring the function of the 6PIN electrical connector, the structure of the independent middle steel sheet is realized, and at the same time, the main body plastic part 20 is located between the first wrapping part 41a and the second wrapping part 51a, which can protect and limit the main body plastic part 20, enhance the strength of the main body plastic part 20 (i.e., the tongue piece), and prevent the main body plastic part 20 from deforming, thereby improving the plug-in life and plug-in feel. In addition, the two middle steel sheets act as grounding terminals, that is, the grounding terminals are made of steel, which improves the product strength, saves terminal materials, improves material utilization, and reduces costs.

[0059] See also Figure 7 and Figure 8 The electrical connector provided in the second embodiment of the present invention is basically the same as the first embodiment, except that, in the present embodiment, a first wrapping portion 41b is provided on the first middle steel sheet 40, and a second wrapping portion 51b is provided on the second middle steel sheet 50, the first wrapping portion 51 and the second wrapping portion are arranged opposite to each other, and the main plastic part 20 is located between the first wrapping portion 41b and the second wrapping portion 51b.

[0060] The first wrapping portion 41 b includes a first grounding PIN contact portion 411 b and a first side portion 412 b . The first grounding PIN contact portion 411 b and the first side portion 412 b form an L-shaped structure. The first grounding PIN contact portion 411 b is located at the top or bottom of the main plastic component 20 .

[0061] The second wrapping portion 51 b includes a second grounding PIN contact portion 511 b and a second side portion 512 b , wherein the second grounding PIN contact portion 511 b and the second side portion 512 b form an L-shaped structure, and the second grounding PIN contact portion 511 b is located at the top or bottom of the main plastic component 20 .

[0062] The main plastic part 20 is wrapped between the two L-shaped wrapping parts.

[0063] Specifically, the first grounding PIN contact portion 411b is located at the top of the main plastic part 20, and the second grounding PIN contact portion 511b is located at the bottom of the main plastic part 20, or;

[0064] The first grounding PIN contact portion 411 b is located at the bottom of the main plastic component 20 , and the second grounding PIN contact portion 511 b is located at the top of the main plastic component 20 .

[0065] That is, the contact portions for grounding on the two middle steel sheets are respectively located on the upper and lower sides of the main plastic part 20 .

[0066] The following effects are achieved by providing the first wrapping portion 41b and the second wrapping portion 51b:

[0067] 1. In the conventional structure, the clamping parts at both ends of the conductive terminal and clamped with the male head are cross-sectional structures of the material, and their height (i.e., the thickness of the copper material) is relatively small. Therefore, during the plugging and unplugging process, it is easy to be misaligned with the male head. Once misaligned, the male head will impact the plastic part during the plugging and unplugging process, causing damage to the plastic part. In this embodiment, by providing the first side edge portion 412b and the second side edge portion 512b, it is no longer a cross-sectional structure, which can increase the height of the clamping part with the male head, and effectively avoid the problem of misalignment with the male head during the plugging and unplugging process;

[0068] 2. In the traditional structure, the clamping parts at both ends of the conductive terminal that are clamped with the male plug are cross-sectional structures of the material. Such cross-sectional structures are bound to have burrs, which will affect the contact stability with the male plug. In the present embodiment, by providing the first side edge portion 412b and the second side edge portion 512b, the surface is smoother than the cross-section, thereby enhancing the contact stability with the male plug.

[0069] In addition, it should be pointed out that for other matters not described in this embodiment, reference can be made to the first embodiment and will not be repeated here.

[0070] According to the electrical connector of this embodiment, the first middle steel sheet 40 and the second middle steel sheet 50 are respectively provided on both sides of the conductive terminal 10, and the first middle steel sheet 40 and the second middle steel sheet 50 are respectively used as the first grounding PIN and the second grounding PIN. Thus, under the premise of ensuring the function of the 6-PIN electrical connector, the structure of the independent middle steel sheet is realized. At the same time, the main body plastic part 20 is located between the first wrapping part 41b and the second wrapping part 51b, which can protect and limit the main body plastic part 20, enhance the strength of the main body plastic part 20 (i.e., the tongue piece), and prevent the main body plastic part 20 from deforming, thereby improving the plug-in life and plug-in feel. In addition, the two middle steel sheets act as grounding terminals, that is, the grounding terminals are made of steel, which improves the product strength, saves terminal materials, improves material utilization, and reduces costs.

[0071] In addition, a third embodiment of the present invention provides an electronic device, which includes at least the electrical connector of the first embodiment or the second embodiment. It should be noted that the electronic device is, for example, a mobile power supply, a wireless headset, an electric shaver, an electric toothbrush, etc.

Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
