Description

Technical Field

[0001] The utility model relates to the technical field of automobile antennas, in particular to a connector and an antenna. Background Art

[0002] The connection between the car antenna (such as a ceramic antenna) and the circuit board is usually in the form of welding, that is, the ceramic antenna is inserted into the PTH hole (Plating Through Hole) of the circuit board, and the ceramic antenna and the circuit board are welded together by soldering to achieve electrical connection between the ceramic antenna and the circuit board.

[0003] However, the welding process often leads to rosin residue, cold joints, cracked joints, excessive tin, sharp edges, insufficient tin and other phenomena; at the same time, additional welding tools and working hours are required, which is inefficient and low-cost; and the harmful gases generated by welding harm the operators and cause inevitable pollution to the environment.

[0004] In addition, there is also a solution to achieve electrical connection between the ceramic antenna and the circuit board through crimping pins. For example, a number of through crimping pin mounting holes are opened on the circuit board, and the electrical connection between the circuit board and the ceramic antenna is achieved through a number of crimping pins, that is, one end of the crimping pin is connected to the ceramic antenna, and the other end of the crimping pin is inserted into the crimping pin mounting hole. Although this type of solution effectively achieves a certain degree of solder-free connection, crimping pins of the same length can only adapt to a part of the circuit boards. Therefore, in actual application, crimping pins of different lengths need to be replaced for circuit boards of different thicknesses, which increases the cost and difficulty of material management.

[0005] Therefore, there is an urgent need for a connector that can solve the above-mentioned problems that are easily caused by the welding process without increasing the production cost. Utility Model Content

[0006] The purpose of the utility model is to solve the problems of high cost, easy damage to human body and pollution, and low compatibility of the existing connection process between antenna and circuit board. The utility model provides a connector that can realize efficient assembly between antenna and circuit board, reduce cost and increase efficiency, do not need welding, and has high compatibility.

[0007] In order to solve the above technical problems, the embodiment of the utility model discloses a connector, comprising:

[0008] A polygonal conductive body, used to be arranged on a circuit board, the polygonal conductive body is provided with a connection slot, the connection slot is used to accommodate a pin of a product, and the connection slot is used to deform so that the connector switches from a first state to a second state;

[0009] In the first state, the connection groove is used for the pin of the product to be squeezed;

[0010] In the second state, the connecting groove is used to clamp the pin of the product so as to electrically connect the product to the polygonal conductive body.

[0011] By adopting the above technical solution, the connector of the embodiment of the present application provides a connection method that can realize the connection between the pin of the product (such as an antenna) and the circuit board without soldering. The connector is used to be pre-set on the circuit board, and it includes a polygonal conductive body with a connection groove, which can be deformed when the pin is inserted so as to wrap and clamp the inserted pin, and make the pin electrically connected to the circuit board. The connector of the embodiment of the present application is simple and efficient, with low cost, and effectively reduces the difficulty of assembling the traditional antenna and the circuit board. There is no need for soldering, thereby avoiding the occurrence of rosin residue, cold solder joints, and other phenomena that are easily produced in the welding process, and also effectively avoids damage to welding operators and pollution to the environment.

[0012] At the same time, the connector of the embodiment of the present application can adapt to circuit boards of different thicknesses and antennas of different sizes and different numbers of pins, has high compatibility, and effectively reduces production, manufacturing and material management costs.

[0013] According to another specific embodiment of the present invention, the polygonal conductive body is a rectangular plate.

[0014] By adopting the above technical solution, the connector adopts a rectangular conductive body, which can reduce the occupied area during actual application (for example, multiple connectors need to be arranged on a circuit board). That is to say, multiple rectangular conductive bodies can be arranged in a more compact layout, that is, the spacing between each rectangular conductive body is reduced. In actual applications, there is no need to increase the spacing between the pins of the product (such as the antenna) and the size of the antenna. The rectangular conductive body of the embodiment of the present application can be inserted in a more compact layout to achieve electrical connection between the antenna and the circuit board.

[0015] According to another specific embodiment of the utility model, the connecting groove includes a accommodating cavity. In the second state, the cavity wall of the accommodating cavity is pressurized to protrude along the thickness direction of the polygonal conductive body, and the cavity wall of the accommodating cavity is used to surround and clamp the pin to limit the movement of the pin along the thickness direction.

[0016] According to another specific embodiment of the present invention, the connecting groove includes a cross groove.

[0017] According to another specific embodiment of the present invention, the polygonal conductive body is made of a conductive elastic material.

[0018] By adopting the above technical solution, the polygonal conductive body of the embodiment of the present application is made of a conductive elastic material, for example, beryllium copper (but not limited thereto), so that on the one hand, the connecting groove can be deformed when the pin is inserted to switch to the above-mentioned second state, thereby clamping the pin to achieve mechanical fixation, and on the other hand, the electrical connection between the pin, the connector, and the circuit board can be achieved on the basis of mechanical fixation.

[0019] An embodiment of the utility model also discloses an antenna, comprising a circuit board, an antenna element and at least one connector in any of the above embodiments, wherein the antenna element comprises at least one pin; at least one connector is connected to the circuit board, and the at least one pin is plugged into the corresponding connector and electrically connected to the corresponding connector.

[0020] By adopting the above technical solution, the antenna of the embodiment of the present application includes one or more of the above connectors pre-set on the circuit board, so that the pins of the antenna element are easily inserted into the corresponding connectors to achieve mechanical fixation and electrical connection between the pins and the circuit board. The assembly of the antenna of the embodiment of the present application is simple and efficient, with low cost and low assembly difficulty. There is no need for welding, thus avoiding the occurrence of rosin residue, cold solder joints, etc. that are easily generated in the welding process, and effectively avoiding damage to welding operators and pollution to the environment.

[0021] According to another specific embodiment of the utility model, the antenna includes a plurality of connectors, the antenna element includes a plurality of pins, the circuit board is provided with a plurality of through holes, the plurality of connectors, the plurality of pins, and the plurality of through holes correspond one to one; the plurality of pins pass through the corresponding through holes and the connecting grooves of the connectors in sequence to switch to the second state.

[0022] According to another specific embodiment of the utility model, a portion of the multiple connectors are horizontally arranged on the circuit board at a first spacing, another portion of the multiple connectors are used to be longitudinally arranged on the circuit board at a second spacing, and the portion of connectors and the other portion of connectors are spaced apart at a third spacing.

[0023] With the above technical solution, since the connector of the embodiment of the present application adopts a polygonal conductive body, when the antenna element is provided with multiple pins (for example, four pins), the corresponding four polygonal conductive bodies can be arranged at a first spacing, a second spacing, and a third spacing, respectively, and the first spacing, the second spacing, and the third spacing are relatively small. For example, the first spacing, the second spacing, and the third spacing are respectively greater than or equal to 0.4 mm, so that the layout is more compact. In other words, when the antenna element is provided with four pins, if a circular connector is used, for example, the spacing between the four connectors is relatively large, then the spacing between the four pins needs to be increased in order to adapt the corresponding connector, thereby increasing the size of the antenna element, which is not conducive to the miniaturization and integration of the antenna. The polygonal conductive body of the connector of the embodiment of the present application can be applied to antenna elements with multiple pins without increasing the size of the antenna.

[0024] At the same time, on the basis of ensuring a compact layout, illustratively, the polygonal conductive body has a larger free portion (i.e., the portion excluding the connection groove connected to the pin). For example, if the SMT (Surface Mounted Technology) process is used to pre-install the connector on the circuit board, it can effectively avoid the problem of short circuit between pins when applying solder paste due to the smaller free portion of the connector.

[0025] According to another specific embodiment of the present invention, any one or more of the plurality of pins are provided with a first groove, and the cavity wall of the accommodating cavity of the connector in the second state is snap-fitted into the first groove.

[0026] By adopting the above technical solution, in order to ensure that the pins and the connecting grooves are not easy to fall out after assembly, a first groove can be opened on any one or more pins. The first groove is used to stop retreat. When the accommodating cavity of the connecting groove is deformed by the pins, the cavity wall of the accommodating cavity can be stuck in the first groove.

[0027] According to another specific embodiment of the utility model, any one or more of the multiple pins are provided with a second groove, the second groove includes an inclined groove wall, the inclined groove wall is used for the cavity wall of the accommodating cavity of the connecting groove to fit, and the cavity wall of the accommodating cavity in the second state is clamped in the second groove.

[0028] By adopting the above technical solution, a second groove can also be provided on any one or more pins, and the second groove includes an inclined groove wall, so that the cavity wall of the deformed accommodating cavity can fit the inclined groove wall and slide into the second groove, thereby facilitating the assembly between the pin and the accommodating cavity and reducing the assembly force. At the same time, the second groove can also be used to stop the pin from falling out. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0044] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0045] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0046] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0047] At present, a welding process is usually used for the electrical connection between a ceramic antenna and a circuit board, that is, a PTH hole (Plating Through Hole) is opened on the circuit board, a pin of the ceramic antenna is inserted into the PTH hole, and then the pin and the PTH hole are welded (eg, soldered).

[0048] During the welding process, phenomena such as rosin residue (referring to flux containing rosin, rosin residue may cause short circuit in circuit board), cold solder joint (referring to improper welding operation resulting in circuit being sometimes connected and sometimes not connected, or the solder joint of ceramic antenna is prone to aging and peeling after long-term use), cracked solder joint (cracks caused by welding stress), excessive tin (too much tin in soldering can easily cause operators to inhale harmful gases, or easily burn the skin), pulled tip (referring to burrs or sharp corners on the surface of the solder joint, which can easily cause short circuit), and insufficient tin (too little tin in soldering can easily cause cold solder joint).

[0049] In addition, the welding process also requires the introduction of welding tooling, which is costly, takes a long time to weld, and has low efficiency.

[0050] Based on this, see Figure 1 and Figure 2 An embodiment of the present application provides an antenna, including an antenna element 1, at least one connector 2 and a circuit board 3.

[0051] The antenna element 1 comprises at least one pin 11, Figure 2 Four pins 11 are shown as an example, but the embodiment of the present application does not limit the number of pins 11. For example, the antenna element 1 may also include one, two, three, five, etc. pins 11. The pins 11 are used for electrical connection between the antenna element 1 and the circuit board 3.

[0052] The connector 2 is used to be pre-set on the circuit board 3 (for example, soldered to the circuit board 3 via a pad), and then the above-mentioned pins 11 of the antenna element 1 are aligned with the connector 2 and inserted, so that the antenna element 1 can be directly fixed and electrically connected to the circuit board 3. Figure 2 Likewise, four connectors 2 are shown as an example, but the embodiment of the present application does not limit the number of connectors 2. For example, the number of connectors 2 can be one, two, three, five, etc.

[0053] Therefore, see Figure 3 and Figure 4 , Figure 3 and Figure 4 The three-dimensional diagrams of the connector 2 in two states (i.e., the first state and the second state described later) are respectively shown. The embodiment of the present application provides a connector 2, such as Figure 3 and Figure 4 As shown, the connector 2 includes a polygonal conductive body 21 .

[0054] Figure 3 and Figure 4 The polygonal conductive body 21 is exemplarily shown as a rectangular plate, but this is only a preferred implementation of the embodiment of the present application. It can also be set to a structure such as a trapezoid, square, triangle, etc. As long as it has a smaller layout area with the same perimeter, it belongs to the protection scope of the embodiment of the present application.

[0055] Exemplarily, the rectangular conductive body 211 has a length of 3 mm, a width of 2.1 mm, and a thickness of 0.2 mm, but the embodiment of the present application does not limit the size of the rectangular conductive body 211. For example, its length can also be 2 mm, its width can be 1.5 mm, and its thickness can be 0.25 mm.

[0056] In a possible implementation, the polygonal conductive body 21 is made of a conductive elastic material, such as beryllium copper, but the present application embodiment is not limited thereto, and other soft metals (such as gold, silver, copper, gallium) may also be used.

[0057] See also Figure 3 and Figure 4 Combined with Figure 2 The rectangular conductive body 211 is used to be pre-set on the circuit board 3. For example, the rectangular conductive body 211 is soldered to the side of the circuit board 3 away from the antenna element 1 (ie, as shown in FIG. 1 ). Figure 2 The side indicated by the Z2 direction).

[0058] The rectangular conductive body 211 is provided with a connection groove 22. In a possible implementation, the connection groove 22 is a cross groove, and illustratively, the groove width of the cross groove is 0.33 mm, but the embodiment of the present application does not limit the shape and size of the connection groove 22. For example, the connection groove 22 can also be provided in a shape of a cross, a cross, etc., and the width of the connection groove 22 can also be 0.1 mm, 0.26 mm, 0.47 mm, etc.

[0059] See also Figures 3 to 6 , Figure 5 The connection state diagram between the connection slot 22 of the connector 2 and the pin 11 is shown as an example. Figure 6 The cross-sectional view of the connection state between the connection groove 22 of the connector 2 and the pin 11 is exemplarily shown. The connection groove 22 is used to accommodate the pin 11 of the antenna element 1, and the connection groove 22 can be deformed so that the connector 2 is changed from the first state (such as Figure 3 ) to switch to the second state (as shown Figures 4 to 6 shown).

[0060] In the first state, the connection slot 22 is used for the pin 11 of the product to be squeezed. That is, in the first state, the connection slot 22 is in an initial state, at which the pin 11 of the antenna element 1 can be inserted into the connection slot 22, but the pin 11 does not penetrate into the connection slot 22.

[0061] In the second state, the pin 11 is inserted into the connection groove 22, and the connection groove 22 is deformed by pressure (such as Figures 4 to 6 As shown), at this time, a portion of the connecting groove 22 can clamp the pin 11, so that the pin 11 is electrically connected to the rectangular conductive body 211.

[0062] By adopting the above technical solution, the antenna of the embodiment of the present application includes one or more of the above-mentioned connectors 2 pre-set on the circuit board 3, so as to facilitate the pin 11 of the antenna element 1 to be inserted into the corresponding connector 2, thereby realizing mechanical fixation and electrical connection between the pin 11 and the circuit board 3.

[0063] Specifically, the connector 2 of the embodiment of the present application provides a solder-free connection method between the pin 11 of the product (such as an antenna) and the circuit board 3. The connector 2 is used to be pre-set on the circuit board 3, and includes a polygonal conductive body 21 with a connection groove, which can be deformed when the pin 11 is inserted so as to wrap and clamp the inserted pin 11, and make the pin 11 and the circuit board 3 electrically connected.

[0064] The antenna of the embodiment of the present application is simple and efficient to assemble, with low cost and low assembly difficulty, and does not require welding, thereby avoiding the occurrence of rosin residue, cold solder joints, and other phenomena that are easily generated in the welding process, and also effectively avoiding damage to welding operators and pollution to the environment. At the same time, the connector 2 of the embodiment of the present application can adapt to circuit boards 3 of different thicknesses and antennas of different sizes and different numbers of pins 11, has high compatibility, and effectively reduces production, manufacturing and material management costs.

[0065] In a possible implementation manner, the connection groove 22 includes a receiving cavity 221. It can be seen that the receiving cavity 221 is located at the intersection of the cross grooves. Figure 3 As shown in FIG. 2 , the accommodating cavity 221 is in the initial state, and the accommodating cavity 221 provides a cavity for the pin 11 to be inserted. Figures 4 to 6 As shown in FIG. 1 , the cavity wall 2211 of the accommodating cavity 221 is squeezed by the pin to extend in the direction of the thickness of the rectangular conductive body 211 and away from the pin 11 (as shown in FIG. 1 ). Figures 4 to 6 At this time, the cavity wall 2211 of the accommodating cavity 221 surrounds and clamps the pin 11, so that the pin 11 cannot be moved along the thickness direction of the rectangular conductive body 211 (as shown in the Z2 direction). Figure 5 and Figure 6 The device moves in the Z direction (shown in FIG. 1 ).

[0066] See also Figure 7 and Figure 8 Combined with Figure 6 In a possible implementation, when the antenna element 1 in the antenna of the embodiment of the present application is provided with four pins 11, four connectors 2 can be provided on the circuit board 3, and at the same time, four through holes 31 are provided on the circuit board 3, and the four connectors 2, the four pins 11, and the four through holes 31 correspond one to one. The above four pins 11 can sequentially pass through the corresponding through holes 31 and the connection slots 22 of the connectors 2 to switch to the above second state.

[0067] Exemplarily, the four connectors 2 can be SMT (Surface Mounted Technology) respectively to the circuit board 3 through the four pads 32. Exemplarily, in order to facilitate the SMT of the connector 2 to the circuit board 3, the surface of the rectangular conductive body 211 can be electroplated, for example, by electroplating tin, but this is only one possible implementation.

[0068] Continue reading Figure 7 and Figure 8 Combined with Figure 6 , two of the four connectors 2 (i.e. Figure 7 and Figure 8 The two connectors 2 are arranged in a horizontal direction along the first direction, that is, the length extension direction of the two connectors 2 (such as Figure 8 The Y1 direction shown in FIG. 1 ) and the length direction of the circuit board 3 (as shown in FIG. Figure 8 The other two connectors 2 (i.e. Figure 7 and Figure 8 The two connectors 2 are arranged longitudinally along the direction of their length (as indicated by b). Figure 8 The Y2 direction shown in FIG. 1 ) and the length direction of the circuit board 3 (as shown in FIG. Figure 8 E direction shown in FIG).

[0069] Since the connector 2 of the embodiment of the present application adopts a rectangular conductive body 211, when the antenna element is provided with a plurality of pins 11 (for example, four pins 11), the corresponding four rectangular conductive bodies 211 can be as follows: Figure 7 and Figure 8 The exemplary layout is arranged on the circuit board 3, and the spacing distance between the four rectangular conductive bodies 211 (eg Figure 8 The first spacing L1, the second spacing L2, and the third spacing L3 shown in the figure are relatively small, making the layout more compact.

[0070] That is to say, when the antenna element 1 is provided with four pins 11, if a circular connector 2 is used, for example, the spacing between the four connectors 2 is relatively large. In this case, the spacing between the four pins 11 needs to be increased in order to adapt to the corresponding connector 2, thereby increasing the size of the antenna element 1, which is not conducive to the miniaturization and integration of the antenna.

[0071] The polygonal conductive body 21 (eg, rectangular conductive body 211 ) of the connector 2 of the embodiment of the present application can be adapted to the antenna element 1 having multiple pins 11 without increasing the size of the antenna.

[0072] At the same time, on the basis of ensuring a compact layout, illustratively, the rectangular conductive body 211 has a larger free portion Q (i.e., excluding the portion of the connection slot 22 connected to the pin 11), so that the connector 2 and the circuit board 3 are more firmly connected, and the connector 2 will not be peeled off from the circuit board 3 when switching from the first state to the second state due to re-assembling the pins. At the same time, when the connector 2 is pre-SMTed on the circuit board 3, the problem of short circuit between the pins 11 when applying solder paste due to the small free portion Q of the connector 2 can be effectively avoided.

[0073] See also Fig. 9 and Fig.10 Combined with Figure 2 In a possible implementation manner, a first groove 12 may be provided in at least one pin 11 in the antenna of the embodiment of the present application. Exemplarily, the first groove 12 is a groove with an arc, and the first groove 12 is used to stop the pin 11 inserted into the connector 2 from moving in the direction of the thickness direction toward the circuit board 3 (such as Figure 2 Movement in the Z1 direction shown in FIG. Fig. 9 and Fig.10 Two first grooves 12 are exemplarily shown in the figure, but one, three, or other number of first grooves 12 may also be provided. The embodiment of the present application does not limit the number of the first grooves 12.

[0074] See also Fig.11 and Fig.12 Combined with Figure 2 In a possible implementation, a second groove 13 may be provided in at least one or more pins 11 in the antenna of the embodiment of the present application. The second groove 13 includes an inclined groove wall 131. When the connector 2 switches from the first state to the second state, the cavity wall 2211 of the deformed accommodating cavity 221 can fit the inclined groove wall 131 and slide into the second groove 13, thereby facilitating the assembly between the pin 11 and the accommodating cavity 221 and reducing the assembly force. At the same time, after sliding into the second groove 13, the second groove 13 can also be used to stop the pin 11 inserted into the accommodating cavity 221 from moving in the thickness direction toward the direction of the circuit board 3 (such as Figure 2 Movement in the Z1 direction shown in FIG. Fig.11 and Fig.12 Two second grooves 13 are exemplarily shown in the figure, but one, three, or other number of second grooves 13 may also be provided. The embodiment of the present application does not limit the number of the second grooves 13.

[0075] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
