Description

Technical Field

[0001] The present invention relates to a power connector, and more particularly to a power connector with a simplified assembly structure. Background Art

[0002] A power connector is a conductor electronic component for connecting electrical circuits. It is widely used in various electrical circuits, playing the role of connecting or disconnecting circuits, or providing power connection between different circuit systems and devices.

[0003] However, as the connector pursues simplified assembly steps and a stable structure, how to design a simple assembly where the terminal can be positioned just by being pushed into the insulating body, and how to improve the current-carrying efficiency of the power connector have become the key research points for those in the power connector manufacturing industry.

[0004] In view of this, the inventor of the present invention has specifically devoted himself to research and combined with the application of theory, and tried his best to solve the above problems, which has become the goal of the inventor's development. Summary of the Invention

[0005] The present invention provides a power connector with a simplified assembly structure. By using the spaced spaces formed between multiple pairs of ribs and the inner front wall and inner rear wall, the conductive sheets passing through the spaced spaces will be abutted by the ribs, and multiple pairs of clamping elastic pieces extending from one end of the two conductive sheets and bent inward relatively, so as to achieve the effects of easy assembly and improved current-carrying efficiency of the power connector.

[0006] In an embodiment of the present invention, a power connector with a simplified assembly structure is provided, including: an insulating housing having two side-by-side through openings at one end and a socket communicating with the two through openings at the other end. The inner wall of each through opening has an inner left wall, an inner right wall, an inner front wall and an inner rear wall, a partition extending across between the inner left wall and the inner right wall, and multiple pairs of ribs protruding from the partition towards the inner front wall and the inner rear wall. Two spaced spaces are formed between the multiple pairs of ribs and the inner front wall and the inner rear wall; and a terminal group including a positive terminal and a negative terminal. The positive terminal and the negative terminal respectively have two opposite conductive sheets and multiple pairs of clamping elastic pieces extending from one end of the two conductive sheets and bent inward relatively. Each of the multiple pairs of clamping elastic pieces passes through the socket, and each of the two conductive sheets passes through each of the two spaced spaces and is abutted by the multiple pairs of ribs.

[0007] Based on the above, when the conductive sheets of the power connector of the present invention are slightly deformed or have a large tolerance, they will generate point friction with the convex ribs in the spacer space. The point friction is smaller than the surface friction, so that the positive terminal and the negative terminal can be smoothly installed in the through hole, so as to achieve that the positive terminal and the negative terminal can be positioned in the insulating housing by being pushed into the through hole, making the power connector of the present invention have the effects of easy assembly and simple assembly.

[0008] Based on the above, the power connector of the present invention uses multiple pairs of clamping elastic sheets connected to the mating card, and the multiple pairs of clamping elastic sheets extend from a single conductive sheet, so that the power connector of the present invention can withstand a large current, so as to achieve excellent current-carrying efficiency of the power connector of the present invention.

[0047] The detailed description and technical content of the present invention will be described below in conjunction with the drawings. However, the attached drawings are only for illustrative purposes and are not intended to limit the present invention.

[0048] Please refer to Figures 1 to 5 As shown, the present invention provides a power connector that can simplify the assembly structure. This power connector 10 is a card edge connector, and the power connector 10 mainly includes an insulating housing 1 and a terminal group 2.

[0049] As Figures 1 to 5As shown, one end of the insulating housing 1 is provided with two juxtaposed left and right through-holes 11, and the other end is provided with a socket 12 communicating with the two through-holes 11. The inner wall of each through-hole 11 has an inner left wall 111, an inner right wall 112, an inner front wall 113 and an inner rear wall 114. A partition piece 115 extending across between the inner left wall 111 and the inner right wall 112 and a plurality of pairs of convex ribs 116 protruding from the partition piece 115 towards the inner front wall 113 and the inner rear wall 114 are provided. Two spaced spaces S are formed between the plurality of pairs of convex ribs 116 and the inner front wall 113 and the inner rear wall 114.

[0050] In addition, two convex blocks 13 are extended from both sides of the insulating housing 1 and are arranged at both ends of the two through-holes 11. Each convex block 13 is provided with a T-shaped groove 131. And the minimum width W1 of the socket 12 in this embodiment is 4.7 mm, but it is not limited thereto.

[0051] As Figures 1 to 5 shown, the terminal group 2 includes a positive terminal 21 and a negative terminal 22. The positive terminal 21 and the negative terminal 22 respectively have two opposite conductive sheets 23 and a plurality of pairs of clamping elastic pieces 24 extending from one end of the two conductive sheets 23 and bent inwards relatively. Each of the plurality of pairs of clamping elastic pieces 24 is inserted through the socket 12, and each of the two conductive sheets 23 is inserted through the two spaced spaces S and is abutted by the plurality of pairs of convex ribs 116.

[0052] Specifically described as follows, each pair of clamping elastic pieces 24 has two ends 241 and two turning points 242 formed between the two conductive sheets 23 and the two ends 241. A spacing A is formed between each pair of clamping elastic pieces 24. The spacing A between each pair of clamping elastic pieces 24 gradually decreases from the two conductive sheets 23 to the two turning points 242 and gradually increases from the two turning points 242 to the two ends 241.

[0053] Among them, the mating card (Card PCB) 200 can be inserted into the insulating housing 1 from the socket 12, and is clamped by the two turning points 242 of the plurality of pairs of clamping elastic pieces 24 and is electrically connected to the positive terminal 21 and the negative terminal 22.

[0054] In addition, the radius of curvature of each turning point 242 in this embodiment is 3 mm. A bending point 243 is formed at the junction of each clamping elastic piece 24 and the conductive sheet 23, and the radius of curvature of each bending point 243 is 2.5 mm.

[0055] Furthermore, the number of pairs of convex ribs 116 in each through-hole 11 is one less than the number of pairs of clamping elastic pieces 24 of the positive terminal 21 and the negative terminal 22, and the plurality of pairs of convex ribs 116 in each through-hole 11 are arranged corresponding to the spacing B between the plurality of pairs of clamping elastic pieces 24 of the positive terminal 21 and the negative terminal 22.

[0056] Furthermore, the thickness H of the positive terminal 21 and the negative terminal 22 in this embodiment is respectively between 0.6 and 0.7 mm, the width W2 of the positive terminal 21 and the negative terminal 22 is respectively between 1.75 and 1.85 mm, and the distance B between two adjacent pairs of clamping elastic pieces 24 is between 0.45 and 0.65 mm, and the distance C between each pair of clamping elastic pieces 24 is 1.15 mm.

[0057] In addition, the positive terminal 21 and the negative terminal 22 respectively have a plurality of pairs of conducting pins 25 extending from the other ends of the two conducting sheets 23, and the plurality of pairs of conducting pins 25 are inserted into a plurality of electrical conducting holes 101 of the circuit board 100, so that the power connector 10 is mounted on the circuit board 100 and is electrically connected to the circuit board 100.

[0058] As Figures 1 to 5 shown, the power connector 10 of the present invention further includes two T-shaped fixing pieces 3, each T-shaped fixing piece 3 is inserted into each T-shaped groove 131, and each T-shaped fixing piece 3 has two fixing feet 31 exposed outside each convex block 13 and arranged on both sides of the plurality of pairs of conducting pins 25, and the two fixing feet 31 are inserted into two fixing holes 102 of the circuit board 100, so that the power connector 10 is stably mounted on the circuit board 100.

[0059] As Figures 1 to 5 shown, in the use state of the power connector 10 of the present invention, a partition piece 115 extending between the inner left wall 111 and the inner right wall 112 and a plurality of pairs of convex ribs 116 protruding from the partition piece 115 towards the inner front wall 113 and the inner rear wall 114 are extended from each through hole 11. A two-spacing space S is formed between the plurality of pairs of convex ribs 116 and the inner front wall 113 and the inner rear wall 114. When each two conducting sheets 23 are inserted through each two-spacing space S, they will be abutted by the plurality of pairs of convex ribs 116.

[0060] Thereby, the insulating housing of the existing power connector is provided with a straight slot for the terminal to pass through. If the terminal is slightly deformed or has a large tolerance, it will generate a surface friction force with the inner wall of the straight slot, resulting in the terminal being difficult to install in the straight slot. In contrast, when the conducting sheet 23 of the power connector 10 of the present invention is slightly deformed or has a large tolerance, it will generate a point friction force with the convex rib 116 in the spacing space S. The point friction force is smaller than the surface friction force, so that the positive terminal 21 and the negative terminal 22 can be smoothly installed in the through hole 11, so that the positive terminal 21 and the negative terminal 22 can be positioned in the insulating housing 1 by being pushed into the through hole 11, making the power connector 10 of the present invention have the effects of easy assembly and simple assembly.

[0061] In addition, when each two conducting sheets 23 are inserted through each two-spacing space S, they will be abutted by the plurality of pairs of convex ribs 116 to separate each two conducting sheets 23, so as to avoid short circuit between the positive terminal 21 and the negative terminal 22, making the power connector 10 of the present invention have the advantage of a stable structure.

[0062] Furthermore, in the power connector 10 of the present invention, a plurality of pairs of clamping elastic pieces 24 are used to connect with the mating card 200, and the plurality of pairs of clamping elastic pieces 24 and the plurality of pairs of conducting pins 25 extend from a single conductive sheet 23, so that the power connector 10 of the present invention can withstand a large current, thereby achieving excellent current-carrying efficiency of the power connector 10 of the present invention.

[0063] In summary, the power connector with a simplified assembly structure of the present invention has not been seen in similar products or publicly used, and has industrial applicability, novelty and progressiveness, fully meeting the requirements for patent application. Therefore, an application is filed according to the Patent Law to protect the rights of the inventor.
