Description

Technical Field

[0001] This utility model relates to the field of communications, and in particular to a detection connector. Background Technology

[0002] When testing electronic components, easy-to-install and disassemble test connectors are typically used to mate with communication connectors to achieve circuit connection. To ensure ease of connection, probes and contacts are usually used for contact connection to transmit electrical signals. With the development of electronic devices, the size of some devices is constantly shrinking to reduce space costs. As the overall size of the device decreases, the size of its communication connector also decreases, resulting in a denser arrangement of contacts, which in turn requires a denser arrangement of the probes.

[0003] However, to achieve a high-density probe arrangement, both the probe diameter and spacing need to be reduced. When the probe diameter is reduced, its bending stiffness is lower, and it is prone to overheating when carrying a large current, making the probe easily damaged and difficult to use in practical applications. Utility Model Content

One side edge of the contact end of the communication pin protrudes to form a guide portion adjacent to the contact portion. The side of the guide portion adjacent to the contact portion is a guide surface. The extending direction of the guide surface has an angle with the third direction. When the contact portion abuts against the contact, the guide surface abuts against the surrounding edge adjacent to the corresponding contact.

[0011] Optionally, the communication connector includes two first insulating frames arranged along the third direction, and two second insulating frames disposed on both sides of the first insulating frames along the first direction.

[0015] The beneficial effects of this invention are as follows: A sheet-like communication pin is provided, with a protruding central portion at the top of the sheet forming a contact area, which connects to the contact point. Compared to traditional probes, the communication pin has a greater length in the third direction, resulting in greater strength, lower resistance, and a larger heat dissipation area, thus achieving a longer service life. Because the contact point is block-shaped and the contact portion of the communication pin is sheet-shaped, the length of the contact point in the first direction is greater than that of the communication pin. Therefore, even if the positions of each communication pin are slightly offset in the first direction, the communication pin can still maintain communication with the contact point, thereby ensuring that all contacts of the detection connector are connected to the communication connector.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] This utility model application protects a detection connector, which is used in conjunction with a communication connector. The communication connector includes a protective surface, on which a plurality of contacts 107 arranged along a first direction are partially raised. The detection connector includes a plurality of communication pins 12 corresponding to each contact 107. The communication pins 12 are plate-shaped and have a contact end 121 and a connecting end 122 opposite to each other along a second direction. The contact end 121 is a strip-shaped structure extending along a third direction, with an angle between the third direction and the first direction. A contact portion 123 is raised in the middle of the contact end 121. The end of the contact portion 123 away from the connecting end 122 is connected to the contact 107. Both the contact 107 and the communication pins 12 are constructed as conductive structures.

[0024] A sheet-shaped communication pin 12 is provided, with a protrusion at the center of the top of the sheet forming a contact portion 123, which connects to the contact point 107. The communication pin 12 has a greater length in the third direction compared to the probe, resulting in greater strength, lower resistance, and a larger heat dissipation area, thus achieving a longer service life. Since the contact point 107 is block-shaped and the contact portion 123 of the communication pin 12 is sheet-shaped, and the length of the contact point 107 in the first direction is greater than that of the communication pin 12, even if the positions of each communication pin 12 are slightly offset in the first direction, it is still guaranteed that the communication pin 12 is connected to the contact point 107, thereby ensuring that each contact 107 of the detection connector is connected to the communication connector.

[0025] Please refer to the following examples for details.

[0026] Example 1: The detection connector shown in a preferred embodiment of this application is used in conjunction with a communication connector. Please refer to... Figure 1 The communication connector is connected to the surface of the second substrate 101 and includes a first insulating frame 102, a second insulating frame 104, a contact 107, a grounding portion 108, and a connecting piece 109. The second substrate 101 is horizontally arranged, and the communication connector is connected to the lower surface of the second substrate.

[0027] The first insulating frame 102 is rectangular in shape and extends horizontally along a first direction, protruding and connected to the lower surface of the second substrate 101. Two first insulating frames 102 are arranged along a third direction perpendicular to the first direction and horizontally. Each first insulating frame 102 includes two surrounding edges 103 extending along the first direction. Contacts 107 are disposed within the first insulating frame 102, are block-shaped, and their bottom surface away from the second substrate 101 is a plane parallel to the lower surface of the second substrate 101, flush with the end of the first insulating frame 102 away from the second substrate 101. Multiple contacts 107 are arranged in a row along the first direction, and two rows of staggered contacts 107 are provided on the inner sides of each of the two first insulating frames 102. Two rows of contacts 107 located within the same first insulating frame 102 form a group. Each row of contacts 107 is adjacent to one of the two surrounding edges 103, and the side of each contact 107 closest to the adjacent surrounding edge 103 is connected to the sidewall of that edge 103. Two rows of rectangular sheet-like connecting pieces 109 are attached to the lower surface of the second substrate 101, located on the outside of the first insulating frame 102 and adjacent to the two surrounding edges 103. Each connecting piece 109 corresponds one-to-one with each contact 107. The first insulating frame 102 is an insulating structure, while the contacts 107 and connecting pieces 109 are conductive structures. Each contact 107 is electrically connected to the circuit embedded in the second substrate 101 through the corresponding connecting piece 109.

[0028] Two second insulating frames 104 are respectively disposed on both sides of the first insulating frame 102 along the first direction, and are both disposed between the two first insulating frames 102. The second insulating frame 104 is constructed as an insulating structure, including an outer frame 105 and an inner frame 106 sleeved inside the outer frame 105. The outer frame 105 is generally constructed as a rectangle with one side open, and its adjacent two side edges extend along the first direction and a third direction respectively, with its edge close to the first insulating frame 102 and extending along the third direction open. The inner frame 106 is generally constructed as an isosceles trapezoid, with its longer base open and facing the first insulating frame 102. The openings of the inner frame 106 and the outer frame 105 are connected to each other, forming the two ends of the second insulating frame 104, and the two ends of the second insulating frame 104 are respectively connected to the adjacent ends of the two first insulating frames 102. The two sides of the second insulating frame 104 extending along the first direction correspond to the two enclosing sides 103 of the two first insulating frames 102 respectively. The second insulating frame 104 has a grounding portion 108 whose shape matches the second insulating frame 104. The grounding portion 108 is constructed as a conductive structure and is electrically connected to the circuit embedded in the second substrate 101.

[0029] Please see Figure 2 The test connector includes a carrier module 1, a mounting module 2, and an alignment block 3.

[0030] Please see Figure 2 and Figure 3The carrier module 1 includes a carrier plate 11 and a clamping plate 13, as well as multiple communication pins 12, grounding pins 15 and inserts 14 mounted on the carrier plate 11. The communication pins 12, grounding pins 15 and inserts 14 are all conductive metal pieces.

[0031] The carrier plate 11 is a rectangular block with a horizontal support surface 111 and a mating surface 112, with the support surface 111 located above the mating surface 112. Multiple communication pins 12 and multiple grounding pins 15 are vertically connected to the support surface 111 of the carrier plate 11, and multiple inserts 14 are vertically connected to the mating surface 112 of the carrier plate 11.

[0032] Please see Figure 1 and Figure 4The communication pin 12 is generally rectangular in shape, extending along a vertical second direction, and has a contact end 121 and a connecting end 122 opposite to each other along the second direction. The connecting end 122 of the communication pin 12 is connected to the support surface 111 of the carrier plate 11 and is connected to the circuit inside the carrier plate 11. The contact end 121 of the communication pin 12 extends along a third direction, and its thickness along the first direction is less than the bottom surface of the contact point 107. A contact portion 123 is formed by protruding from the middle of the contact end 121 of the communication pin 12 towards one side edge. The contact portion 123 is generally equilateral triangular in shape with a rounded top. A right-angled trapezoidal guide portion 124 is formed by protruding from the edge of the contact portion 123 adjacent to the contact end 121 of the communication pin 12. The top of the guide portion 124 is rounded and its height is higher than the top of the contact portion 123. The guide portion 124 extends along the second direction away from the contact portion 123, and its side closest to the contact portion 123 forms a guide surface 125, which forms an angle with the second direction. The guide surface 125 connects to the contact portion 123, and the connection point is rounded. The edge of the contact end 121 of the communication pin 12 away from the guide portion 124 is recessed downwards, forming a right-angled triangle that communicates with the edge of the contact end 121 of the communication pin 12, and one side of the recess is parallel to the guide surface 125. Multiple communication pins 12 are arranged in a row along the first direction, with the edges of each communication pin 12 flush with each other. Any two adjacent communication pins 12 are arranged in different directions, so that the guide surface 125 is located on different sides of the contact portion 123, even if the tops of the contact portions 123 of two adjacent communication pins 12 are misaligned in the third direction. The detection connector of this embodiment includes two rows of communication pins 12, each corresponding to one of two sets of contacts 107. Within each row, communication pins 12 with the same orientation correspond to the same row of contacts 107, while adjacent communication pins 12 correspond to contacts 107 in different rows. When the communication connector is pressed down so that the tip of the contact portion 123 of each communication pin 12 abuts against the bottom surface of each contact 107, the guide surface 125 of each communication pin 12 abuts against the outer edge of the surrounding edge 103 adjacent to the corresponding contact 107. The guide portion 124 guides the relative displacement of the communication connector and the detection connector, helping to ensure that the tip of the contact portion 123 of each communication pin 12 accurately abuts against the bottom surface of the corresponding contact 107.

[0033] Please see Figure 1 and Figure 3The grounding pin 15 is constructed as a rectangular plate, and its width along the third direction is the same as that of the communication pin 12. In this embodiment, a total of four grounding pins 15 are provided, located on both sides of the two rows of communication pins 12 along the first direction, parallel to each communication pin 12, and flush with the communication pins 12 on both sides along the third direction. The end of the grounding pin 15 away from the support plate 11 protrudes to form two energized parts 151 and one snap-fit ​​part 152. The two energized parts 151 have the same structure, both constructed as isosceles triangles with rounded tops. The two energized parts 151 are interconnected and communicate with the side of the grounding pin 15 adjacent to another grounding pin 15. The snap-fit ​​part 152 is constructed as a right trapezoid with rounded tops, and its side away from the energized part 151 extends along the second direction. Its side near the energized part 151 is the snap-fit ​​surface 153, which is connected to the edge of the energized part 151 by rounded corners. When the top tip of the contact portion 123 of each communication pin 12 abuts against the bottom surface of the corresponding contact 107, the top tip of the energized portion 151 of the grounding pin 15 abuts against the grounding portion 108, and the locking surface 153 abuts against the outer edge of the outer frame 105. The locking portion 152 serves as a guide.

[0034] Please see Figure 3 The insert plate is a rectangular sheet with an end that tapers into an isosceles triangle shape away from the carrier plate 11. The insert plate extends along a second direction and is parallel to a third direction. Its end near the carrier plate 11 is inserted into the carrier plate 11 and connected to the internal circuitry. The insert plate has a lower density than the communication pins 12 and grounding pins 15. Insert plates corresponding to the communication pins 12 in the same orientation are arranged along the first direction. Two rows of insert plates correspond to the two orientations of the communication pins 12, respectively, and are arranged along the third direction. Two insert plates corresponding to the grounding pins 15 are located at the ends of the two rows of insert plates along the first direction and at the middle of the two rows along the third direction. Each insert plate is electrically connected to its corresponding communication pin 12 or grounding pin 15 via the internal circuitry of the carrier plate 11.

[0035] Please see Figure 2 The clamping plate 13 is generally rectangular in shape, with its length in the first direction greater than that of the support plate 11, and its width in the third direction equal to that of the support plate 11. A groove is formed in the middle of the clamping plate 13 to fit the support plate 11, so that the mating surface 112 of the support plate 11 is embedded in the clamping plate 13, and the supporting surface 111 of the support plate 11 protrudes from the surface of the clamping plate 13. Multiple holes for insert pieces 14 to pass through are formed on the bottom surface of the groove in the clamping plate 13, and these holes penetrate the clamping plate 13. Each insert piece 14 corresponds to a specific hole.

[0036] Mounting module 2 includes mounting plate 21, guide post 22, and floating spring 24. Mounting plate 21 is generally rectangular, with a receiving groove formed on its side near the first substrate to accommodate the support module 1. Support plate 11 and clamping plate 13 are embedded in the receiving groove, and clamping plate 13 is fixedly connected to mounting plate 21 by fixing bolts 131. Two fixing bolts 131 are located on opposite sides of support plate 11 along a first direction, clamping support plate 11 between clamping plate 13 and mounting plate 21. At this time, the surface of clamping plate 13 away from support plate 11 is flush with the side of mounting plate 21 near the first substrate. Mounting plate 21 is connected to the surface of the first substrate of the electronic device, and the surface of the first substrate has multiple insertion holes that mate with each insert 14. Inserts 14 are inserted into these holes and electrically connected to the internal circuitry of the electronic device. The bottom surface of the receiving groove has two elongated holes 211 extending along a first direction. The holes 211 fit into the support assembly and penetrate the mounting plate 21. Each communication pin 12 and grounding pin 15 passes through the holes 211. Four guide posts 22 form a rectangle and are located on both sides of the support plate 11 along the first direction. The guide posts 22 are cylindrical and extend along a second direction, with their ends fixedly connected to the first substrate. They penetrate the mounting plate 21 through through holes that fit into the mounting plate 21. Four floating springs 24 are respectively located on the side of the guide posts 22 near the support plate 11 and adjacent to the guide posts 22. The four floating springs 24 form a rectangle. The mounting plate 21 has first spring grooves corresponding to the positions of the floating springs 24, so that the floating springs 24 are partially embedded in the first spring grooves.

[0037] The alignment block 3 is a rectangular block with through holes for the guide posts 22 to be inserted. A second spring groove for the floating spring 24 is formed at its bottom, allowing the floating spring 24 to be partially embedded within the second spring groove. The total depth of the first and second spring grooves is less than the length of the floating spring 24. When the alignment block 3 is not subjected to external pressure, a gap exists between the alignment block 3 and the mounting plate 21. A mounting bolt 23, positioned along the second direction, connects the alignment block 3 and the mounting plate 21. When the alignment block 3 is not subjected to external pressure, the bottom of the head of the mounting bolt 23 abuts against the alignment block 3. Besides connecting the alignment block 3 and the mounting plate 21, the mounting bolt 23 also limits the rebound of the alignment block 3 and assists in guiding the alignment block 3 as it slides up and down. A partial recess on the upper surface of the alignment block 3 forms a substrate groove 31 that fits the shape of the second substrate 101. Since the shape of the second substrate 101 is not constrained in this embodiment, the shape of the substrate groove 31 is not described. The bottom of the substrate groove 31 is partially recessed to form an alignment groove 32 that mates with the communication connector. The alignment groove 32 includes two first inner walls 321 extending along a first direction, four second inner walls 322 extending along the first direction, and two third inner walls 323 extending along a third direction. The two first inner walls 321 respectively mate with the enclosure edges 103 of the two first insulating frames 102 away from the other first insulating frame 102. The two second inner walls 322 and one third inner wall 323 form a rectangle with an opening on one side and mate with the outer frame 105 of the second insulating frame 104. The first inner walls 321 and the second inner walls 322, and the second inner walls 322 and the third inner walls 323 are connected by arc-shaped inner walls, and the arc-shaped inner walls do not interfere with the communication connector. The bottom surface of the alignment groove 32 has a plurality of pin slots 324 extending to the bottom surface of the alignment block 3, for each communication pin 12 and grounding pin 15 to pass through. When the alignment block 3 is not subjected to force, the contact portion 123 of the communication pin 12 and the energized portion 151 of the grounding pin 15 are both embedded in the pin groove 324, providing protection. When the connector and communication connector are being tested for alignment, the second substrate 101 is embedded in the substrate groove 31, and the communication connector is embedded in the alignment groove 32, and a downward force is applied to the alignment block 3. At this time, the alignment block 3 slides along the guide post 22 toward the mounting plate 21, so that the contact portion 123 of the communication pin 12 and the energized portion 151 of the grounding pin 15 are exposed outside the pin groove 324 and electrically connected to the communication connector respectively.

[0038] In this embodiment, both the positioning block 3 and the mounting plate 21 are constructed as insulated structures, and the carrier plate 11 is insulated overall except for the embedded circuit structure. The pin slot 324 has gaps between itself and each communication pin 12 and grounding pin 15, facilitating installation and allowing for small-amplitude elastic deformation and displacement of each communication pin 12 and grounding pin 15. This ensures that the contact portion 123 of each communication pin 12 accurately abuts against the bottom surface of the contact point 107 under the guidance of the guide surface 125, and that the energized portion 151 of each grounding pin 15 accurately abuts against the grounding portion 108 under the guidance of the snap-fit ​​surface 153.

[0039] In this embodiment, the surface of the mounting plate 21 away from the first substrate is thinned around the support plate 11, which helps to save costs, reduce thickness, and also helps with the alignment and guidance between the alignment block 3 and the mounting plate 21.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
