Abstract
Description
[0001] The present invention relates to an electrical connection terminal and an electrical connection structure, in particular a connection terminal with a stop element and a spring element that serves for stable fixing in a housing chamber, and a connection structure that is equipped with this connection terminal.
[0002] Currently, commercially available electrical connectors (terminals) are primarily used in the transmission of electronic signals and electrical power. Their primary function is to establish an electrical connection between different electronic devices to ensure reliable signal transmission. However, with the ongoing miniaturization of electronic devices, the size of electrical connectors is also subject to strict miniaturization requirements. These structural constraints make it increasingly difficult to securely integrate terminals into the structure of electrical connectors, which can lead to unstable connection performance.
[0003] The invention is based on the objective of providing an electrical connection terminal whose spring element has an L-shaped section that serves to fix the electrical connection terminal stably in the housing chamber after insertion into the electrical connection housing.
[0004] According to the present invention, an electrical connection terminal is provided, comprising a mating housing. The mating housing has a mating opening, a stop element arranged remotely from the mating connection, and an adjacent spring element separate from the stop element. The spring element consists of an inclined first section, a second section extending in the upright direction, and a third section extending longitudinally along the mating housing. The upright direction is perpendicular to the longitudinal direction. The second section is arranged between the first and third sections. The second and third sections of the spring element form an L-shape. The stop element comprises a stop section extending along the longitudinal direction and an auxiliary section inclined relative to the first section of the spring element, the stop section being connected to the auxiliary section.The auxiliary section serves to support the end of the first section of the spring element.
[0005] According to the invention, the above-mentioned mating housing has a contact element, and the auxiliary section also includes a bending area that is bent in the direction of the contact element.
[0006] According to the invention, the aforementioned support element has a first projection that extends away from the bending area. The first projection of the support element is separated from the bending area of the auxiliary section in order to define a space of movement in which the first projection can move along the uprighting path.
[0007] According to the invention, the aforementioned support element has a first projection that extends away from the bending area. The first projection of the support element is separated from the bending area of the auxiliary section, thereby limiting a space of movement in which the first projection can move along the uprighting path.
[0008] According to the invention, the bottom section of the mating housing, the contact element and the stop element define a mating space into which a conductive pin can be inserted.
[0009] According to the invention, the mating opening of the mating housing serves to receive the conductive pin, so that the conductive pin is inserted into the mating space.
[0010] According to the invention, the bottom section of the mating housing has a second projection extending towards the mounting element, wherein the position of the first projection in the upright position corresponds to the position of the second projection.
[0011] According to the invention, the electrical connection terminal also comprises a terminal block. The terminal block is connected to the mating housing and formed integrally with it. The terminal block serves to accommodate a signal line, so that the conductive pin is electrically connected to the signal line via the mating housing and the terminal block.
[0012] Another embodiment of the present invention relates to an electrical connection structure.
[0013] According to the invention, an electrical connection structure is further provided, comprising an electrical connection terminal and an electrical connection housing. The connection housing has a main body comprising a chamber, a separating block arranged on the main body, and a first locking zone and a second locking zone on both sides of the separating block. When the electrical connection terminal is inserted into the chamber, the second and third sections of the spring element are in contact with the separating block, and the stop section of the stop element comes into contact with the second locking zone to securely fix the connection terminal in the chamber.
[0014] According to the invention, the electrical connection housing has a positioning lock. One end of the positioning lock is provided with a first locking section, while a second locking section is located in the middle region of the positioning lock. When the positioning lock is locked to the main body, the first section of the spring element of the electrical connection terminal is partially positioned in the first locking zone, and the second locking section of the positioning lock is located in the second locking zone of the main body.
[0015] According to the invention, the electrical connection housing has a mating end. When the electrical connection terminal is stably fixed in the chamber, the mating end of the electrical connection housing is aligned with the mating opening of the electrical connection terminal.
[0016] According to the invention, the electrical connection terminal of the electrical connection structure has a spring element whose second and third sections form an L-shape. The L-shaped section of the spring element of the electrical connection terminal can make contact with the disconnect block of the electrical connection housing. Furthermore, the electrical connection terminal has a stop element separate from the spring element, which can make contact with the second locking zone of the electrical connection housing. This enables the electrical connection terminal not only to receive the conductive pin but also to be stably fixed in the chamber of the electrical connection housing, thus facilitating an electrical connection between the electronic devices.
[0017] The invention and its embodiments are explained in more detail below with reference to the drawing. The drawing shows: Fig. 1 a perspective view of the electrical connection terminal according to an embodiment of the present invention; Fig. 2 a longitudinal section through a mating housing of the electrical connection terminal according to an embodiment of the present invention; Fig. 3 a perspective view of the electrical connection terminal according to an embodiment of the present invention, which is connected to a signal line; Fig. 4 a longitudinal section through an electrical connection structure according to an embodiment of the present invention, which is connected to a signal line; Fig. 5 an enlarged section of the electrical connection structure according to the invention Fig. 4; Fig. 6 a perspective view in which a conductive pin according to an embodiment of the present invention is inserted into the electrical connection structure; and Fig. 7 a longitudinal section of the electrical connection structure according to an embodiment of the present invention in which the conductive pin is connected.
[0018] In the Fig. 1 and Fig. Figure 2 shows an electrical connection terminal 100 with a mating housing 110. The mating housing 110 of the electrical connection terminal 100 has a mating opening 112, a stop element 114 located a distance from the mating housing 112, and an adjacent spring element 116 that is separate from the stop element 114. For example, the mating opening 112 and the stop element 114 are located on opposite sides of the mating housing 110, while the spring element 116 is located between the mating opening 112 and the stop element 114. The spring element 116 of the mating housing 110 comprises a first section 1161, which is inclined relative to the longitudinal direction D2 of the mating housing 110, a second section 1162, which extends in the upright position D1, and a third section 1163, which extends along the longitudinal direction D2 of the mating housing 110. The upright D1 is perpendicular to the longitudinal direction D2.
[0019] In some embodiments, the second section 1162 of the spring element 116 is arranged between the first section 1161 and the third section 1163. It is noteworthy that the second section 1162 and the third section 1163 of the spring element 116 form an L-shape. The stop element 114 of the mating housing 110 has a stop section 1142 extending along the longitudinal direction D2 of the mating housing 110, and an auxiliary section 1144 inclined towards the first section 1161 of the spring element 116. The stop section 1142 of the stop element 114 is connected to the auxiliary section 1144 of the stop element 114, the auxiliary section 1144 of the stop element 114 serving to support the end of the first section 1161 of the spring element 116.
[0020] In some embodiments, the mating housing 110 has a contact element 118. The contact element 118 of the mating housing 110 is located between a bottom section 111 of the mating housing 110 and the spring element 116 of the mating housing 110. Furthermore, the auxiliary section 1144 of the stop element 114 is provided with a bending region 1145 that is curved in the direction of the contact element 118. The bending region 1145 of the auxiliary section 1144 is curved in the direction of the bottom section 111 of the mating housing 110. The contact element 118 of the mating housing 110 has a first projection 1182 that extends opposite to the bending direction of the bending region 1145. In other words, the installation element 118 has a first projection 1182 that protrudes towards the bottom section 111 of the mating housing 110.It is noteworthy that the first projection 1182 of the fixture element 118, which protrudes towards the bottom section 111 of the mating housing 110, is separated from the bending area 1145 of the auxiliary section 1144 in order to define a range of motion A1 in which the first projection 1182 can move along the upright D1.
[0021] In some embodiments, the bottom section 111 of the mating housing 110, the contact element 118 and the stop element 114 define a mating space A2 into which a conductive pin 300 [see Fig. 6] can be inserted. More precisely, the mating opening 112 of the mating housing 110 can be used to receive the conductive pin 300, so that the tip of the conductive pin 300 penetrates the mating space A2. Once the tip of the conductive pin 300 has entered the mating space A2, the first projection 1182 of the mounting element 118, which extends towards the bottom section 111 of the mating housing 110, can support the conductive pin 300, so that the conductive pin 300 can be stably connected to the electrical connection terminal 100. In addition, the movement space A1 of the mating housing 110 allows the first projection 1182 of the mounting element 118 to move along the upright D1 when the conductive pin 300 is inserted into the mating housing 110.
[0022] Furthermore, the base section 111 of the mating housing 110 has a second projection 113 that extends towards the mounting element 118. It is noteworthy that the position of the first projection 1182 of the mounting element 118 in orientation D1 corresponds to the position of the second projection 113 on the base section 111 of the mating housing 110. The mutually directed projections, the first projection 1182 and the second projection 113, contribute to the fixation. This ensures that the conductive pin 300 remains stably connected to the electrical connection terminal 100 once its tip has penetrated the mating space A2.
[0023] With reference to the Fig. 3 to Fig. 5 shows Fig. 3 a schematic representation of an electrical connection terminal 100 according to an embodiment of the present invention, which is connected to a signal line 400. Fig. Figure 4 shows a longitudinal section of an electrical connection structure 200 according to an embodiment of the present invention, in which the signal line 400 is connected, while Fig. 5 an enlarged section of the electrical connection structure 200 from Fig. 4 shows. In the Fig. The electrical connection terminal 100 also has a terminal block 120, as shown in sections 3 to 5. The terminal block 120 is connected to the mating housing 110, with the terminal block 120 and the mating housing 110 being formed as a single unit.
[0024] In some embodiments, the terminal block 120 is arranged on the side of the mating housing 110 facing away from the mating connector 112. The terminal block 120 serves to accommodate the signal line 400. For example, the signal line 400 can be inserted into the terminal block 120 and wired so that the signal line 400 is permanently connected to the terminal block 120. When the conductive pin 300 is inserted into the mating housing 110, the arrangement of the mating housing 110 and the terminal block 120 electrically connects the conductive pin 300 to the signal line 400, thus enabling signal transmission between the conductive pin 300 and the signal line 400.
[0025] Furthermore, the electrical connection structure 200 includes the electrical connection terminal 100 described above, as well as an electrical connection housing 210. The electrical connection housing 210 of the electrical connection structure 200 has a main body 212. The main body 212 of the electrical connection housing 210 has a chamber 214, a separating block 216 arranged on the main body 212, and a first locking zone 217 and a second locking zone 218 located on opposite sides of the separating block 216. It is worth noting that once the electrical connection terminal 100 is inserted into the chamber 214 of the electrical connection housing 210, the L-shaped second section 1162 and the third section 1163 of the spring element 116 of the electrical connection terminal 100 can come into contact with the separating block 216 of the electrical connection housing 210.Furthermore, the stop section 1142 of the stop element 114 of the electrical connection terminal 100 can come into contact with the second locking zone 218 of the electrical connection housing 210, thereby securely fixing the electrical connection terminal 100 in the chamber 214 of the electrical connection housing 210 and fulfilling a stop function. In addition, the electrical connection housing 210 has a mating end 2111. When the electrical connection terminal 100 is securely fixed in the chamber 214 of the electrical connection housing 210, the mating end 2111 of the electrical connection housing 210 is aligned with the mating opening 112 of the electrical connection terminal 100.
[0026] With reference to the Fig. 6 and Fig. 7 shows Fig. 6 a schematic representation of the electrical connection terminal 100 according to an embodiment of the present invention, in which the conductive pin 300 and the signal line 400 are connected. Fig. Figure 7 shows a longitudinal section in which the conductive pin 300 is inserted into the electrical connection structure 200. In the Fig. 6 and Fig. The electrical connection housing 210 also has a positioning lock 211. One side of the positioning lock 211 of the electrical connection housing 210 is provided with a first locking section 213, while the middle part of the positioning lock 211 has a second locking section 215. It is noteworthy that when the positioning lock 211 of the electrical connection housing 210 is locked to the main body 212, the second locking section 215 of the positioning lock 211 is positioned in the second locking zone 218 of the main body 212, and the first section 1161 of the spring element 116 of the electrical connection terminal 100 is partially arranged in the first locking zone 217 of the electrical connection housing 210.
[0027] In summary, the electrical connection terminal 100 of the electrical connection structure 200 has a spring element 116, the second section 1162 and third section 1163 of which form an L-shape. The L-shaped part of the spring element 116 of the electrical connection terminal 100 can contact the disconnect block 216 of the electrical connection housing 210. Furthermore, the electrical connection terminal 100 has a stop element 114, separate from the spring element 116, which can contact the second locking zone 218 of the electrical connection housing 210 [see Fig.4]. This enables the electrical connection terminal 100 not only to accommodate the conductive pin 300, but also to be stably fixed in the chamber 214 of the electrical connection housing 210 to ensure the electrical connection between multiple electronic devices and to complete the signal transmission. In short, thanks to the design of the electrical connection terminal 100 described above, the terminal remains stable within the structure even when the electrical connection structure 200 is miniaturized, and even under limited space conditions.
