Description

Technical Field

[0001] This utility model relates to a bidirectional wire connection device that can connect different wires together to ensure smooth current flow. In particular, it relates to a bidirectional wire connection device that can prevent wire misalignment and current convergence each time a wire is inserted, thereby reducing the possibility of two wires failing to conduct. Background Technology

[0002] Generally speaking, wire connection devices are mainly used to electrically connect electrical products to an external power source, so that the electrical products can be temporarily or permanently electrically connected to the external power source through the electrical connection device.

[0003] Common wire connection devices typically consist of a housing and a connecting unit. The housing is hollow and has a socket that connects to the interior of the housing. The connecting unit is located inside the housing, to one side of the socket. When a wire is inserted through the socket into the housing, the wire is pressed against the connecting unit, allowing the connecting unit to deform and clamp the wire. However, when the connecting unit deforms due to the pressure of the wire, it creates an elastic force acting on the wire. Consequently, when the wire passes through the socket... When the wire is inserted into the housing through the insertion hole, the wire is easily misaligned with the connecting unit due to the elastic force. This prevents the wire from being clamped by the connecting unit, resulting in poor current conduction and increasing the risk of electric shock and short circuit. When the wire is misaligned with the connecting unit, it must be repeatedly inserted into the housing. The connecting unit's structure will reduce the elastic force due to repeated insertion and removal of the wire, causing the connecting unit to become fatigued and unable to clamp the wire. This renders the connecting unit unusable and shortens the service life of the wire connection device. Utility Model Content

[0004] The main purpose of this utility model is to provide an improved bidirectional wire connection device with an improved structure, so that when the two wires are inserted into the improved bidirectional wire connection device, the two wires can avoid being misaligned on the bus, and the two wires can make reliable contact with the bus to prevent the two wires from failing to conduct, thereby reducing the risk of electric shock and short circuit.

[0005] The secondary objective of this utility model is to provide a bidirectional wire connection device with an improved housing structure, so that when the bus is installed inside the improved housing, the improved housing can restrict the position of the bus to prevent the bus from moving significantly inside the housing. Furthermore, when the wire is inserted into the bidirectional wire connection device and pushed against the bus, the bus can avoid displacement relative to the housing, ensuring that the wire can still contact the bus when it is inserted into the bidirectional wire connection device again.

[0006] Another objective of this invention is to provide a bidirectional wire connection device with an improved housing structure, which allows the cover to be quickly assembled onto the base, and simultaneously positions the spring steel sheet in the default position inside the housing when the cover is assembled onto the base.

[0007] To achieve the aforementioned objective, this utility model provides a bidirectional conductor connection device for electrically connecting a left conductor to a right conductor, and includes: a housing, a spring steel sheet, and a bus.

[0008] The housing has a left insertion hole and a right insertion hole on its left and right opposite sides, and has an insertion channel inside that connects the left insertion hole and the right insertion hole. Inside the insertion channel, the housing has a left guide part and a right guide part. The left guide part forms a left limiting space aligned with the left insertion hole, and the right guide part forms a right limiting space aligned with the right insertion hole.

[0009] The spring steel sheet is disposed inside the wiring channel and has a left clamping portion located between the left wiring hole and the left guide portion, a right clamping portion located between the right wiring hole and the right guide portion, and a connecting portion located between the left clamping portion and the right clamping portion. The connecting portion can extend from the left guide portion to the right guide portion. The bus is disposed inside the wiring channel and connected to the connecting portion. The bus has a left busbar adjacent to the left limiting space and a right busbar adjacent to the right limiting space.

[0010] The left wire passes through the left insertion hole into the interior of the insertion channel. The left guide portion guides the left wire into the interior of the left limiting space and restricts the left wire from being adjacent to the left busbar. The right wire passes through the right insertion hole into the interior of the insertion channel. The right guide portion guides the right wire into the interior of the right limiting space and restricts the right wire from being adjacent to the right busbar.

[0011] In this embodiment, the housing further includes a test hole located between the left guide portion and the right guide portion, and the bus further includes a test bus located between the left bus portion and the right bus portion, the test bus being aligned with the test hole. The upper surface of the housing includes a left protrusion and a right protrusion spaced apart to the right of the left protrusion. The upper surface of the housing forms a recessed area extending from the left and right protrusions toward the center, respectively. The test hole is located in the recessed area, such that the height of either the left or right protrusion is higher than the height of the test hole.

[0012] The housing has a recessed section inside the wiring channel forming a left slot near the left wiring hole and a right slot near the right wiring hole. The left slot is located below the left protrusion and can be inserted by a portion of the left clamping wire. The right slot is located below the right protrusion and can be inserted by a portion of the right clamping wire. The left channel protrudes to form a left insertion block, which, along with a portion of the left clamping wire, is inserted into the left slot. The right channel protrudes to form a right insertion block, which, along with a portion of the right clamping wire, is inserted into the right slot.

[0013] In a preferred embodiment, the housing comprises: a base and a cover. The base has a support portion to support the spring steel sheet and the bus. The base has a left channel portion and a right channel portion on opposite sides of the support portion. The left channel portion has a left insertion hole through it, and the right channel portion has a right insertion hole through it. The cover has a test hole, a left slot, a right slot, a left guide portion, and a right guide portion, and can be assembled to the base, such that the cover and the base together form the insertion channel, and the left guide portion and the right guide portion are inserted into the support portion.

[0014] In another embodiment, the left guide portion has a left baffle extending downward from the upper side of the housing and two left partitions extending from the left baffle toward the left insertion hole, such that the left baffle and the two left partitions together surround to form the left limiting space, and the left wire inserted into the left limiting space can abut against the left baffle, thereby the left baffle can prevent the left wire from passing through the left limiting space;

[0015] The right guide portion has a right baffle extending downward from the upper side of the housing and two right partitions extending from the right baffle toward the right insertion hole, such that the right baffle and the two right partitions together form the right limiting space, and the right wire inserted into the right limiting space can abut against the right baffle, thereby the right baffle can prevent the right wire from passing through the right limiting space.

[0016] The left baffle and the edges of the two left partitions together form a lower left opening, which is located below the left limiting space and adjacent to the left busbar. The edges of the two left partitions away from the left baffle together form a left opening adjacent to the lower left opening, which is located to the left of the left limiting space and close to the left insertion hole. The right baffle and the edges of the two right partitions together form a lower right opening, which is located below the right limiting space and adjacent to the right busbar. The edges of the two right partitions away from the right baffle together form a right opening adjacent to the lower right opening, which is located to the right of the right limiting space and close to the right insertion hole. The test hole is formed between the left and right baffles.

[0017] In another embodiment, the left guide portion has two left partitions arranged at an incline to each other, and the left limiting space is formed between the two left partitions, such that the left limiting space gradually expands toward the left insertion hole, and the left wire inserted into the left limiting space can abut against the two left partitions, so that the two left partitions can prevent the left wire from passing through the left limiting space.

[0018] Additionally, the right guide portion has two right partitions arranged at an incline to each other, and the right limiting space is formed between the two right partitions, such that the right limiting space gradually expands from the direction toward the right insertion hole, and the right wire inserted into the right limiting space can abut against the two right partitions, so that the two right partitions can prevent the right wire from passing through the right limiting space.

[0019] In the two embodiments described above, the left partition protrudes to form a left partition protrusion that can contact the left side of the bus, and the right partition protrudes to form a right partition protrusion that can contact the right side of the bus. The left partition protrusion and the right partition protrusion are used to restrict the bus from being adjacent to the left limiting space and the right limiting space at the same time. At the same time, the left partition protrusion presses down against the left clamping part, and the right partition protrusion presses down against the right clamping part.

[0020] Furthermore, the housing is further provided with a left positioning block located inside the left insertion hole and a right positioning block located inside the right insertion hole. The left positioning block and the right positioning block are respectively located on the left and right sides of the bus, so that the bus is limited between the left positioning block and the right positioning block, and the left positioning block and the right positioning block can restrict the left bus and the right bus to be continuously adjacent to the left limiting space and the right limiting space, respectively.

[0021] Furthermore, the connecting portion has two extension sections with a width smaller than the bus and a connecting section with a width larger than the extension sections. The two extension sections are respectively formed in the left clamping portion and the right clamping portion. The connecting section is located between the two extension sections and is used to connect to the bus, such that a part of the bus covers the two extension sections and the connecting section, thereby forming a gap between the remaining part of the bus and the two extension sections. The housing further has a front positioning block and a rear positioning block inside the insertion channel. The front positioning block has a first front positioning part and a second front positioning part with a height lower than the first front positioning part. The rear positioning block has a first rear positioning part and a second rear positioning part with a height lower than the first rear positioning part. The first front positioning part and the first rear positioning part are respectively adjacent to the front and rear sides of the bus. The second front positioning part and the second rear positioning part are respectively inserted into the gap and are respectively adjacent to the front and rear sides of the extension section.

[0022] The left clamping part is provided with a left connecting frame, through which a left window is formed, and a left spring piece is formed at the top edge of the left window, which is away from the left window, so that the left spring piece enters the interior of the left limiting space. The right clamping part is provided with a right connecting frame, through which a right window is formed, and a right spring piece is formed at the top edge of the right window, which is away from the right window, so that the right spring piece enters the interior of the right limiting space.

[0023] The feature of this utility model is that the inside of the housing is provided with left and right guide parts, and the left and right guide parts individually surround to form left and right limiting spaces, and the left and right limiting spaces are respectively located at the left and right plug holes. In this way, when two wires are inserted into the plug channel through the left and right plug holes respectively, one wire can be guided into the left limiting space through the left guide part, and the other wire can be guided into the right limiting space through the right guide part. This prevents the two wires from being misaligned with the bus, and ensures that both wires can make reliable contact with the bus to prevent the two wires from failing to conduct, thereby reducing the risk of electric shock and short circuit.

[0024] In addition, the housing has left and right positioning blocks inside the left and right insertion holes respectively. The left positioning block can contact the left side of the bus, while the right positioning block can contact the right side of the bus at the same time, so that the bus is limited between the left and right positioning blocks. This allows the left and right bus junctions to be continuously adjacent to the left limiting space of the left guide and the right limiting space of the right guide, respectively. In this way, when the wire is inserted into the bidirectional wire connection device and pushes against the bus, the bus can avoid displacement relative to the housing by the left and right positioning blocks, ensuring that the wire can still contact the bus when it is inserted into the bidirectional wire connection device again.

[0025] Furthermore, the cover of the housing is provided with left and right slots, and the left and right channels of the base of the housing protrude to form a left insertion block and a right insertion block, respectively. When the cover is connected to the base, the left and right insertion blocks will be inserted into the left and right slots respectively to achieve the function of quickly assembling the cover into the base. At the same time, the left and right clamping parts of the spring steel sheet can be embedded into the left and right slots respectively, so that the spring steel sheet is positioned in the default position inside the housing.

Detailed Implementation

[0046] The present invention will be further described below with reference to specific embodiments and accompanying drawings. The advantages and features of the present invention will become clearer with the description.

[0047] Please see Figure 1 and Figure 2 As shown, the bidirectional conductor connecting device 1 of this utility model is used to connect multiple conductors 40 (such as...) Figure 16A As shown, they are electrically connected together, and the bidirectional wire connection device 1 is mainly composed of a housing 10, a spring steel sheet 20 and a bus 30.

[0048] Please see Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the housing 10 is mainly composed of a base 11 and a cover 12. The central section of the base 11 has a support portion 111 to support the spring steel sheet 20 and the bus 30. The base 11 forms a left channel portion 112 on the left side of the support portion 111, and a right channel portion 113 is formed on the right side of the support portion 111, spaced apart from the right side of the left channel portion 112. The support portion 111 is provided with a support base plate 111a and a cover 12. A front bearing side plate 111b and a rear bearing side plate 111c are provided. The bearing base plate 111a is located between the left and right passage portions 112 and 113. The front and rear bearing side plates 111b and 111c are located on the front and rear sides of the bearing base plate 111a, respectively. The bearing base plate 111a, the front bearing side plate 111b, and the rear bearing side plate 111c together form a bearing space 111d. Both the front and rear bearing side plates 111b and 111c protrude. A locking block 111e is formed outside the bearing space 111d, as shown in the figure. The bearing part 111 has a front positioning block 114 and a rear positioning block 115 inside the bearing space 111d. The front positioning block 114 is located at the junction between the bearing base plate 111a and the front bearing side plate 111b, while the rear positioning block 115 is located at the junction between the bearing base plate 111a and the rear bearing side plate 111c. The front positioning block 114 has a first front positioning part 114a adjacent to the front bearing side plate 111b and a second front positioning part 114b with a height lower than the first front positioning part 114a, so that the front positioning block 114 has a stepped appearance. The rear positioning block 115 has a first rear positioning part 115a adjacent to the rear bearing side plate 111c and a second rear positioning part 115b with a height lower than the first rear positioning part 115a, so that the rear positioning block 115 has a stepped appearance.

[0049] Additionally, the left channel portion 112 of the base body 11 extends laterally to form a left insertion hole 112a to connect to the bearing space 111d of the bearing portion 111. Furthermore, a left positioning block 116 protrudes from the left insertion hole 112a in the left channel portion 112, and a left insertion block 117 protrudes from the top surface of the left channel portion 112 in a direction away from the left insertion hole 112a. The right channel portion 113 of the base body 11 extends laterally to form a right insertion hole 113a to connect to the bearing space 111d. Furthermore, a right positioning block 118 protrudes from the right insertion hole 113a in the right channel portion 113, and a right insertion block 119 protrudes from the top surface of the right channel portion 113 in a direction away from the right insertion hole 113a.

[0050] Please see Figure 2 , Figure 6 , Figure 7 , Figure 8and Figure 9 As shown, the cover 12 of the housing 10 has three parts: a top cover plate 121, a front cover plate 122, and a rear cover plate 123. The front and rear cover plates 122 and 123 are located on the front and rear sides of the top cover plate 121, respectively, so that the top cover plate 121, the front cover plate 122, and the rear cover plate 123 together form a cover space 124. The top cover plate 121 protrudes from the outside of the cover space 124 to form a left protrusion 121a and a right protrusion 121b spaced apart to the right of the left protrusion 121a. The cover 12 gradually concaves from the left protrusion 121a and the right protrusion 121b toward the center of the cover 12 to form a recess located between the left and right protrusions 121a and 121b. As shown in the figure, in the recessed area 121c, the top plate 121 forms a left guide portion 125 near the left protrusion 121a and a right guide portion 126 near the right protrusion 121b. The top plate 121 is recessed in the interior of the cover space 124 to form a left slot 121d located to the left of the left guide portion 125 and a right slot 121e located to the right of the right guide portion 126. The left slot 121d is located below the left protrusion 121a, and the right slot 121e is located below the right protrusion 121b. The front and rear side plates 122 and 123 of the cover 12 both pass through to form a locking hole 127 to connect to the cover space 124.

[0051] In this embodiment, the left guide portion 125 of the cover 12 has a left baffle 125a extending downward from the top cover plate 121 and two left partitions 125b extending from the left baffle 125a toward the left side of the top cover plate 121, such that the left baffle 125a and the two left partitions 125b together form a left limiting space 125c. Each left partition 125b protrudes downward toward the direction away from the top cover plate 121 to form a left partition protrusion 125d. The lower edge of the left baffle 125a and the lower edge of the two left partitions 125b together form a lower left opening 125e communicating with the left limiting space 125c. The edges away from the left baffle 125a together form a left opening 125f adjacent to the lower left opening 125e, as shown in the figure. Each left partition 125b has a left inclined section 125b1 inclinedly disposed on the left baffle 125a and a left horizontal section 125b2 formed at the end of the left inclined section 125b1. The two left inclined sections 125b1 are arranged at an inclination towards each other and are parallel to each other. Thus, the left limiting space 125c gradually expands from the left baffle 125a toward the left opening 125f. In addition, the right guide portion 126 of the cover 12 has a right baffle 126a extending downward from the top cover plate 121 and two right baffles 126a. A right partition 126b extends towards the right side of the top cover 121, such that the right baffle 126a and the two right partitions 126b together form a right limiting space 126c. Each right partition 126b protrudes downwards away from the top cover 121 to form a right partition protrusion 126d. The lower edge of the right baffle 126a and the lower edges of the two right partitions 126b together form a lower right opening 126e communicating with the right limiting space 126c. The edges of the two right partitions 126b away from the right baffle 126a together form a right opening 126f adjacent to the lower right opening 126e. As shown in the figure, each right partition 126b has... There is a right inclined segment 126b1 inclinedly disposed on the right baffle 126a and a right horizontal segment 126b2 formed at the end of the right inclined segment 126b1. The two right inclined segments 126b1 are arranged at an inclination to each other and are parallel to each other. As a result, the right limiting space 126c gradually expands from the right baffle 126a toward the right opening 126f. A test hole 128 penetrating through the top plate 121 is provided between the left baffle 125a and the right baffle 126a. The test hole 128 is formed at the lowest point of the recessed area 121c, so that the height of the highest point of the left convex part 121a and the right convex part 121b is higher than the highest point of the test hole 128.

[0052] Please see Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 7 and Figure 9As shown, the cover 12 of the housing 10 is close to the base 11 of the housing 10, such that the front and rear bearing side plates 111b and 111c of the base 11 penetrate into the cover space 124 of the cover 12. Consequently, the front and rear bearing side plates 111b and 111c are located between the front and rear cover side plates 122 and 123 of the cover 12, allowing the left insertion block 117 of the base 11 to penetrate into the left slot 121d of the cover 12, while the right insertion block of the base 11... 119 can be inserted into the right slot 121e of the cover 12, so that the locking block 111e of the base 11 can be reliably engaged one-to-one with the locking hole 127 of the cover 12. This allows the base 11 to be assembled onto the cover 12, so that the bearing space 111d of the base 11 and the cover space 124 together form a wiring channel 13 located inside the housing 10. The wiring channel 13 will then connect to the left and right wiring holes 112a and 113a of the base 11. In this embodiment... When the base 11 is assembled onto the cover 12, the left and right guide portions 125 and 126 of the housing 10 are located in the bearing space 111d. Consequently, the left and right guide portions 125 and 126 are located between the front and rear bearing side plates 111b and 111c of the base 11. The left limiting space 125c of the left guide portion 125 is located opposite the left insertion hole 112a, making the left guide portion 125 close to the left insertion hole 112a. The right guide portion... The right limiting space 126c of 126 is located at the right insertion hole 113a, so that the right guide part 126 is close to the right insertion hole 113a. In addition, the left and right slots 121d and 121e of the cover 12 are close to the left and right insertion holes 112a and 113a, respectively. The cross-sectional profile of the insertion channel 13 in the front-back direction is smaller than the profile of the left opening 125f of the left guide part 125 and the profile of the right opening 126f of the right guide part 126.

[0053] Please see Figure 2 and Figure 12As shown, the spring steel sheet 20 has a connecting portion 21, a left clamping portion 22, and a right clamping portion 23. The connecting portion 21 is located between the left and right clamping portions 22 and 23. The connecting portion 21 has two extension sections 211 with a width smaller than the main line 30 and a connecting section 212 with a width larger than the extension sections 211. One extension section 211 is formed in the left clamping portion 22, and the other extension section 211 is formed in the right clamping portion 23. The connecting section 212 is located between the two extension sections 211. The left clamping portion 22 has a left connecting frame 221 formed in one of the extension sections 211. The left clamping portion 22 forms a left window 222 through the left connecting frame 221, making the left connecting frame 221 ring-shaped. The top edge of the left window 222 extends to form a left spring that is away from the left window 222. The left spring 223 is positioned so that its end away from the top edge of the left window 222 can approach one of the extension sections 211. The right clamping part 23 is provided with a right connecting frame 231 formed in the other extension section 211. The right clamping part 23 passes through the right connecting frame 231 to form a right window 232, making the right connecting frame 231 ring-shaped. A right spring 233 extends from the top edge of the right window 232, away from the right window 232, so that the end of the right spring 233 away from the top edge of the right window 232 can approach the other extension section 211. In addition, the bus 30 is connected to the connecting section 212, so that a part of the bus 30 covers the connecting section 212 and the two extension sections 211. Thus, a gap S is formed between the remaining part of the bus 30 and the two extension sections 211.

[0054] Please see Figure 2 , Figure 13 , Figure 14 and Figure 15As shown, when the cover 12 of the housing 10 is installed on the base 11 of the housing 10, the left connecting frame 221 of the left clamping part 22 and the left inserting block 117 of the base 11 are inserted into the left slot 121d of the cover 12, while the right connecting frame 231 of the right clamping part 23 and the right inserting block 119 of the base 11 are inserted into the right slot 121e of the cover 12, so that the left clamping part 22 is located between the left guide part 125 of the cover 12 and the left channel part 112 of the base 11, so that the left clamping part 22 is located between the left guide part 125 of the cover 12 and the left channel part 112 of the base 11, so that the left... The left opening 125f of the limiting space 125c is close to the left insertion hole 112a of the left through block 117, while the right clamping part 23 is located between the right guide part 126 of the cover 12 and the right channel part 113 of the seat 11, so that the right opening 126f of the right limiting space 126c is close to the right insertion hole 113a of the right through block 119, resulting in both the spring steel sheet 20 and the bus 30 being able to be installed inside the insertion channel 13 of the housing 10. Specifically, when the spring steel sheet 20 is located in the insertion channel 1... When the left spring 223 of the left clamping part 22 extends into the left limiting space 125c of the left guide part 125, the right spring 233 of the right clamping part 23 extends into the right limiting space 126c of the right guide part 126, and the connecting part 21 can span from the left guide part 125 to the right guide part 126 to be located between the left and right positioning blocks 116 and 118 of the seat body 11. At the same time, the second front positioning part 114b of the front positioning block 114 passes through the gap S and is adjacent to the spring. The second rear positioning part 115b of the positioning block 115 is inserted into the gap S and adjacent to the rear side of the extension section 211 of the steel sheet 20. Thus, the second front positioning part 114b and the second rear positioning part 115b are located on the front and rear sides of the extension section 211, respectively, so that the second front positioning part 114b and the second rear positioning part 115b can limit the front and rear movement distance of the spring steel sheet 20 to avoid the spring steel sheet 20 from having a large range of displacement relative to the housing 10.

[0055] As shown in the figure, because the bus 30 is connected to the connecting section 212 of the connecting part 21, the bus 30 can simultaneously be adjacent to the lower left opening 125e of the left limiting space 125c and the lower right opening 126e of the right limiting space 126c, as well as the housing 10. This results in a portion of the bus 30 being adjacent to the left limiting space 125c and configured as a left bus 31, while another portion of the bus 30 is adjacent to the right limiting space 126c and configured as a right bus 32. The remaining portion of the bus 30 is located between the left and right bus 31 and 32. A test busbar 33 is provided to test the test hole 128 located in the housing 10. This allows the user to use a testing tool to reach into the test hole 128 and touch the test busbar 33, thereby testing whether the conductivity of the bus 30 is normal. When the bus 30 is located inside the wiring channel 13 of the housing 10, both the left positioning block 116 of the base 11 and the left partition protrusion 125d of the left guide 125 contact the left busbar 31 of the bus 30, while the right positioning block 118 of the base 11 and... Both the right partition protrusion 126d of the right guide portion 126 and the right bus portion 32 of the bus 30 contact each other, so that the bus 30 is limited between the left and right positioning blocks 116, 118 and the left and right partition protrusions 125d, 126d. Furthermore, the left and right positioning blocks 116, 118 and the left and right partition protrusions 125d, 126d are used to restrict the left bus portion 31 and the right bus portion 32 from continuously being adjacent to the left limiting space 125c and the right limiting space 126c, respectively. Simultaneously, the left partition protrusion 125d will... The left connecting frame 221 of the left clamping part 22 is pressed down, while the right partition protrusion 126d is pressed down against the right connecting frame 231 of the right clamping part 23. The first front positioning part 114a of the front positioning block 114 is adjacent to the front side of the bus 30, and the first rear positioning part 115a of the rear positioning block 115 is adjacent to the rear side of the bus 30. This allows the first front positioning part 114a and the first rear positioning part 115a to limit the forward and backward movement distance of the bus 30 to avoid the bus 30 from undergoing a large range of displacement relative to the housing 10.

[0056] Please see Figure 16A , Figure 16B and Figure 16CAs shown, in a specific application of the bidirectional wire connection device 1 in conjunction with two wires 40, one of the wires 40 is designated as a left wire 41, which is inserted into the wire insertion channel 13 of the housing 10 through the left insertion hole 112a of the housing 10. The left wire 41 first passes through the left window 222 of the left clamping part 22, and then the left wire 41 pushes against the left spring 223 of the left clamping part 22, causing the left spring 223 to deform toward the top plate 121 of the cover 12. Next, the left wire 41 contacts one of the left partitions 125b of the left guide part 125, so that the left wire 41 is guided through the left partition 125b into the left limiting space 125c of the left guide part 125, allowing the left wire 41 to be adjacent to the left busbar 30. In the process of the left conductor 41 entering the left limiting space 125c, it can avoid misalignment with the left bus section 31 of the bus 30. During the process of the left conductor 41 entering the left limiting space 125c, the left conductor 41 will pass through the left spring 223, and the deformed left spring 223 will push down against the left conductor 41, so that the left conductor 41 can make reliable contact with the left bus section 31. In this embodiment, when the left conductor 41 enters the left limiting space 125c, the left conductor 41 will abut against the left baffle 125a of the left guide section 125, so that the left baffle 125a can prevent the left conductor 41 from passing through the left limiting space 125c, and thus the left conductor 41 will not pass through the test hole 128 of the housing 10.

[0057] Additionally, another wire 40 is configured as a right wire 42, which is inserted into the wiring channel 13 of the housing 10 through the right wiring hole 113a of the housing 10. The right wire 42 first passes through the right window 232 of the right clamping part 23, and then pushes against the right spring 233 of the right clamping part 23, causing the right spring 233 to deform towards the top plate 121 of the cover 12. Next, the right wire 42 contacts one of the right partitions 126b of the right guide part 126, allowing the right wire 42 to pass through the right partition 126b and be guided into the right limiting space 126c of the right guide part 126. This allows the right wire 42 to be adjacent to the right busbar 32 of the bus 30, thus preventing misalignment with the right busbar 32 of the bus 30 during its insertion into the right limiting space 126c. During the process of the right wire 42 passing through the right limiting space 126c, the right wire 42 will pass through the right spring 233, and the deformed right spring 233 will push down against the right wire 42, so that the right wire 42 can make reliable contact with the right bus 32. In this way, the left and right wires 41 and 42 can make reliable contact with the left and right bus 31 and 32 of the bus 30 to prevent the left and right wires 41 and 42 from failing to conduct, which can reduce the risk of electric shock and short circuit. In this embodiment, when the right wire 42 passes through the right limiting space 126c, the right wire 42 will abut against the right baffle 126a of the right guide 126, so that the right baffle 126a can prevent the right wire 42 from passing through the right limiting space 126c, and thus the right wire 42 will not pass through the test hole 128 of the housing 10.

[0058] However, when the left and right guide wires 41 and 42 are inserted into the left and right limiting spaces 125c and 126c respectively, the left and right guide wires 41 and 42 individually abut against the left baffle 125a of the left guide part 125 and the right baffle 126a of the right guide part 126. This is only for illustrative purposes, and is as follows: Figure 16DAs shown, when the left wire 41 passes through the left limiting space 125c of the left guide portion 125, because both left partitions 125b of the left guide portion 125 are inclinedly arranged on the left baffle 125a of the left guide portion 125, the left wire 41 simultaneously abuts against the left inclined section 125b1 of the two left partitions 125b. Consequently, the left wire 41 is spaced apart from the left baffle 125a, causing the two left partitions 125b to prevent the left wire 41 from passing through the left limiting space 125c. Similarly, the left wire 41 will not pass through the test hole 1 of the housing 10. 28. In addition, when the right wire 42 passes through the right limiting space 126c of the right guide portion 126, since both right partitions 126b of the right guide portion 126 are inclinedly arranged on the right baffle 126a of the right guide portion 126, the right wire 42 simultaneously abuts against the right inclined section 126b1 of the two right partitions 126b. As a result, the right wire 42 is spaced apart from the right baffle 126a, so that the two right partitions 126b can prevent the right wire 42 from passing through the right limiting space 126c, and similarly prevent the right wire 42 from passing through the test hole 128.

[0059] The above description is illustrative only and not restrictive. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope of the invention, and all such modifications, variations or equivalents will fall within the protection scope of the invention.
