Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electric connectors, and in particular relates to a sheet-type plug pin and an electric connection structure. Background Art
[0002] The electrical connection structure has always been one of the most important structures in the car. The reliability of its connection performance will directly affect the performance of the car and the safety of the passengers on the car. At present, the electrical connection structure in the car is mostly a pin-and-socket structure. Since the chip pin is smaller than the general pin under the same current capacity, it can better meet the market demand for high performance and low cost; therefore, the chip pin and the socket compatible with the chip pin have gradually become the mainstream structure of the electrical connection structure in the car.
[0003] In the existing electrical connection structure using sheet-type pins, such as the connector disclosed in the Chinese invention application with application publication number CN115579659A, the sheet-type pins mostly adopt an integrally formed straight sheet structure. A conductive sheet is provided on the socket for the sheet-type pin to be electrically connected, and a spring claw that can be elastically deformed is provided on the conductive sheet. When the sheet-type pin is inserted into the socket, the spring claw is tightly attached to the sheet-type pin under the action of its own elastic force to ensure the reliability of the electrical connection between the sheet-type pin and the socket. The conductive sheet is generally directly fixed to the inside of the socket by welding, crimping, riveting, forced installation, etc. When the technician uses ultrasonic welding to connect the wires to the tail end of the socket, the vibration during ultrasonic welding can easily cause the conductive sheet to fall off from the inside of the socket. In addition, the conductive sheet is relatively thin. When the technician uses ultrasonic welding to connect the wires to the tail end of the socket, the spring claw on the conductive sheet is very likely to be deformed or broken due to the vibration during ultrasonic welding. Therefore, the electrical connection reliability of the above-mentioned electrical connection structure using sheet-type pins is poor, which is easy to threaten the performance of the car and the safety of the passengers on the car.

[0036] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.
[0037] The principle of the electrical connection structure of the utility model is as follows:
[0038] An electrical connection structure, the structure of which can refer to Figure 1 or Figure 2 As shown, it includes a sheet pin 1 and a socket 2 adapted to the sheet pin 1. A conductive sheet 3 is provided between the sheet pin 1 and the socket 2 for realizing electrical connection between the two. The conductive sheet 3 is fixedly arranged on the sheet pin 1, and an elastic contact portion 11 is provided on the conductive sheet 3. Since the conductive sheet 3 is located on the sheet pin 1, the possibility of the conductive sheet 3 being damaged or deformed due to the vibration of ultrasonic welding when the socket is wired is effectively avoided, thereby ensuring a reliable electrical connection relationship between the sheet pin 1 and the socket 2. In addition, compared with the technical solution in which the conductive sheet 3 is located in the socket 2, the conductive sheet 3 is arranged on the sheet pin 1, which makes it easier to ensure the fixed connection relationship between the conductive sheet 3 and the sheet pin 1, and can avoid the technical problem of the conductive sheet 3 falling off due to the failure of the connection between the two as much as possible; at the same time, it is also convenient for the contact member GAP value size to remain within a stable range during mass production.
[0039] Therefore, the above solution can ensure the reliability of the electrical connection structure on the car, and at the same time provide great protection for the performance of the car and the safety of the passengers on the car. Even under harsh working conditions such as car bumps and engine vibrations, the electrical connection structure can ensure a reliable electrical connection relationship.
[0040] Based on the above principle, the embodiment 1 of the electrical connection structure of the utility model is:
[0041] An electrical connection structure, the structure of which can refer to Figure 1 or Figure 2 As shown, it includes a sheet-type pin 1 and a socket 2 adapted to the sheet-type pin 1. Figure 5 or Figure 6 As shown, the sheet pin 1 is provided with a conductive sheet 3 for realizing electrical connection between the sheet pin 1 and the plug hole 2 , and the conductive sheet 3 has an elastic contact portion 11 .
[0042] The tails of the sheet pin 1 and the socket 2 are both provided with connection parts for electrically connecting to the device by crimping, welding or screwing. Figure 1 As shown, the tail of the sheet-shaped pin and the socket 2 are both flat sheets, so that they can be connected to the circuit of the device by crimping or welding. Figure 2 As shown, the tail of the sheet-shaped pin is provided with a through hole 4 so as to be screwed into the circuit of the device by a fastener.
[0043] The key point of this embodiment is that the conductive sheet 3 is a straight sheet conductive sheet 5, and its specific structure can be referred to Figure 7 As shown. The straight sheet conductive sheet 5 is arranged on one side of the sheet pin 1, or on both sides of the sheet pin 1, to ensure the reliability of the electrical connection between the sheet pin 1 and the socket 2. Such a structure is relatively simple, easy to process and install. Alternatively, the conductive sheet 3 can also be a U-shaped conductive sheet 6. The structure of the U-shaped conductive sheet 6 can be specifically referred to Figure 8 and Fig. 9 As shown, it includes two main bodies 7 arranged opposite to each other and a connecting portion 8 connected between the same sides of the two main bodies 7. The connecting portion 8 and the two main bodies 7 together form a U-shaped structure. The U-shaped conductive sheet 6 clamps and fixes one end of the chip pin 1 in the U-shaped cavity of the U-shaped conductive sheet 6, that is, one end of the chip pin 1 is clamped and fixed between the two main bodies 7 arranged opposite to each other, so as to ensure that the U-shaped conductive sheet 6 is in full contact with and reliably fixed to the chip pin 1, thereby ensuring the reliability of the electrical connection between the chip pin 1 and the socket 2.
[0044] On this basis, the conductive sheet 3 can include an elastic spring sheet 9 having an elastic contact portion 11 and a pressure edge 10, and the two ends of the elastic spring sheet 9 are respectively fixed on the two side edges of the pressure edge 10. For the straight sheet conductive sheet 5, the pressure edge 10 is the four side edges of the straight sheet conductive sheet 5; for the U-shaped conductive sheet 6, the pressure edge 10 is the four side edges of the aforementioned main body 7. Since both ends of the elastic spring sheet 9 are fixed on the pressure edge 10, it is not easy to be damaged or deformed due to high-frequency vibration. In specific implementation, the two ends of the elastic spring sheet 9 can be welded on the pressure edge 10, or can be integrally formed with the pressure edge 10. Of course, in order to facilitate processing, the conductive sheet 3 can also include a main body 7 and a spring claw hanging from the main body 7. When the elastic spring sheet 9 is provided on the conductive sheet 3, the elastic spring sheet 9 is preferably in an arched structure, and the outer surface of the middle section of the arched structure constitutes an elastic contact portion 11 for contacting and conducting with the adapter socket 2. Such a structure can ensure that the elastic spring 9 has sufficient elastic holding force and can provide reliable elastic force to ensure the electrical connection between the sheet pin 1 and the socket 2. The elastic spring 9 is arranged in parallel on the conductive sheet 3 along the width direction of the sheet pin 1 to ensure that there are enough contact points on the sheet pin 1, thereby ensuring the reliability of the electrical connection between the sheet pin 1 and the socket 2. Even in a high-frequency vibration environment, the sheet pin 1 and the socket 2 still have strong plugging stability. The specific number of elastic springs 9 arranged on the conductive sheet 3 is determined according to actual needs and technical level. For example, 10, 12, 14, 16 elastic springs 9 can be arranged in parallel on the conductive sheet 3.
[0045] The edge 10 of the conductive sheet 3 can be fixed to the chip pin 1 by welding or riveting, so that the conductive sheet 3 and the chip pin 1 have a sufficient fixed connection area, thereby having a reliable fixed connection relationship. When the conductive sheet 3 is fixed to the chip pin 1 by direct welding or riveting, the structural appearance of the chip pin 1 and the conductive sheet 3 can be referred to Figure 5 The conductive sheet 3 can also be fixedly mounted on the sheet-type pin 1 through the U-shaped pressing sleeve 12. For the specific structure, please refer to Figure 6As shown. The two side walls of the U-shaped pressing sleeve 12 are provided with pressing grooves with openings facing each other, so as to press and fix the two pressing edges 10 arranged in parallel along the width direction of the conductive sheet 3 on the sheet pin 1. When the conductive sheet 3 adopts a straight sheet conductive sheet 5, the straight sheet conductive sheet 5 needs to be placed in advance at a designated position on one side or both sides of the sheet pin 1, and then the U-shaped pressing sleeve 12 is sleeved on the sheet pin 1, so that the two pressing edges 10 arranged in parallel along the width direction on the straight sheet conductive sheet 5 are synchronously inserted into the pressing groove with the sheet pin 1, so as to achieve a fixed connection between the conductive sheet 3 and the sheet pin 1. When the conductive sheet 3 adopts a U-shaped conductive sheet 6, the U-shaped conductive sheet 6 needs to be pre-clamped on the sheet pin 1, and then the U-shaped pressing sleeve 12 is sleeved on the sheet pin 1, so that the two pressing edges 10 arranged in parallel along the width direction on the two main bodies 7 of the U-shaped conductive sheet 6 are synchronously inserted into the pressing groove with the sheet pin 1, so as to achieve a fixed connection between the conductive sheet 3 and the sheet pin 1. At this time, the connecting part between the two side arms of the U-shaped pressing sleeve 12 is pressed tightly on the connecting part 8 of the U-shaped conductive sheet 6. In addition, the connecting part between the two side arms of the U-shaped pressing sleeve 12 can be provided with a guiding slope 20 so that the sheet pin 1 can be quickly inserted into the socket 2.
[0046] Of course, the conductive sheet 3 can also be directly fixedly mounted on the relevant structure of the sheet pin 1, or fixedly mounted on the sheet pin 1 through the structure of the conductive sheet 3 itself. For example, two clipping edges extending along the width direction of the sheet pin 1 can be set on the sheet pin 1, and the two clipping edges are arranged oppositely to form a clipping groove extending along the width direction of the sheet pin 1. The straight sheet conductive sheet 5 is inserted into the clipping groove along the width direction of the sheet pin 1 to achieve fixed connection. Alternatively, bendable connecting sheets can be set on both sides of the two main bodies 7 of the U-shaped conductive sheet 6, and the connecting sheets located on the same side but on different main bodies 7 can be bent relative to each other. A clip hook is set on one of the connecting sheets, and a clip window is set on the connecting sheet opposite to it. Stop grooves are set on both sides of the sheet pin 1. After one end of the sheet pin 1 is clamped between the two oppositely arranged main bodies 7, a pair of opposite connecting sheets on the two main bodies 7 extend into the stop groove and snap fit each other, so that the U-shaped conductive sheet 6 is tightly held on the sheet pin 1 to achieve fixation.
[0047] No matter which of the above-mentioned fixed connection methods is adopted, a reliable fixed connection between the conductive sheet 3 and the sheet pin 1 can be guaranteed, and the fixed connection method is simple and reliable, avoiding the risk of connection failure between the conductive sheet 3 and the sheet pin 1. At the same time, the elastic spring sheet 9 on the conductive sheet 3 is not easy to be damaged or deformed, effectively ensuring the reliability of the electrical connection structure.
[0048] Based on the above principle, the second embodiment of the electrical connection structure of the utility model is:
[0049] On the basis of Example 1, the socket 2 of the electrical connection structure can be a fork-shaped structure formed by bending a sheet metal integrally. The fork-shaped structure specifically includes a pair of side walls that are directly stamped integrally from a strip and arranged opposite to each other. A gap is left at the front end portion between the side walls to form an opening of the fork-shaped structure. The opening is used to form an insertion slot 13 for inserting the sheet-type pin 1. The rear section of the side wall is pressed together to form a connection end 14 for connecting to the circuit. The above-mentioned socket 2 can adapt to the sheet-type pin 1 inserted at different angles, which can be referred to Figure 3 As shown, the chip pin 1 can be inserted into the insertion slot 13 of the socket 2 along the direction of 90° and 180° with the socket 2. Such a setting can achieve multi-angle wiring with a single structure of the socket 2 and the chip pin 1, and there is no need to specifically set the corresponding socket 2 and the chip pin 1 according to the specific wiring angle requirements, which effectively reduces the specifications of the socket 2 and the chip pin 1; at the same time, it realizes the standardization of product contacts and effectively reduces the management cost. Of course, you can refer to Figure 4 The jack 2 in the embodiment can also be a fork-shaped structure formed by split connection. The fork-shaped structure is specifically composed of a straight sheet-shaped component and a Z-shaped component. The side edge of the Z-shaped component extending outwards and one end of the straight sheet-shaped component form an opening of the fork-shaped structure, and the opening forms an insertion slot 13 for inserting the sheet-type pin 1; the other side edge fits with the other end of the straight sheet-shaped component to form a connection end 14 for connecting to the circuit.
[0050] The key point of this embodiment is that a retaining sleeve 15 is provided at the opening of the fork-shaped structure to prevent the opening of the fork-shaped structure from being greatly deformed, and at the same time ensure the structural strength of the socket 2. In this way, the socket 2 can be prevented from being loosened after multiple plugging and unplugging, so that the socket 2 can always apply a stable positive force to the two conductive sheets 3. The retaining sleeve 15 is provided with an insertion port 16 at the front opening position and the opening position of any one or both sides of the fork-shaped structure, so as to ensure that the sheet pin 1 can be inserted into the insertion slot 13 of the socket 2 along the direction of 90° and 180° with the socket 2. On this basis, a positioning installation groove 17 can be provided on the socket 2, and a bendable positioning installation piece 18 can be provided on the retaining sleeve 15, and the positioning installation piece 18 can be bent and inserted into the positioning installation groove 17, so as to position and install the retaining sleeve 15 on the socket 2. Such a structure can ensure a stable and fixed connection between the socket 2 and the retaining sleeve 15, thereby making the retaining effect of the retaining sleeve 15 on the socket 2 more reliable. A fixing spring piece 19 may also be provided on the outer sheath so as to fix the jack 2 on the device.
