[0005]

[0001] The present invention relates to a connector with a substrate.

Background Art

[0002] Conventionally, a compression type connector that presses against and connects to a connection object such as a substrate is known. The structure of this type of connector is disclosed in, for example, Patent Document 1 below. The conventional compression type connector disclosed in Patent Document 1 below is configured as an electrical connector (1) provided with contacts (20) having an elastic spring portion (23), as shown in FIG. 26. In this electrical connector (1), a plurality of contacts (20) are arranged in an aligned state.

[0003] The contact (20) has a substrate connection portion (22) soldered to the first circuit board (30) and a contact portion (24) that contacts the second circuit board (40). An elastic spring portion (23) having spring properties is provided between the substrate connection portion (22) and the contact portion (24). By pressing the second circuit board (40) from above the contact (20) attached by soldering on the first circuit board (30), the elastic spring portion (23) of the contact (20) exhibits spring properties, generating a contact pressure between the second circuit board (40) and the contact (20). Note that the reference numerals related to the description of the prior art documents are distinguished from the embodiments of the present invention by adding parentheses.

[0004] And in the conventional compression connector, screwing has been used for attachment (fixing) to the substrate.

Patent Document 1

[0006] However, when fixing a compression connector to a circuit board with screws, the conventional method involves attaching the nut from the circuit board side opposite to the connector mounting side, and then tightening the screw from the connector mounting side. In this conventional technique, the worker has to hold the connector and nut in place with their hand while tightening the screw, which makes the connector installation (fixing) process difficult. In other words, the conventional screw-fastening structure for fixing compression connectors to circuit boards requires a separate component, the nut, in addition to the screw, which presents problems such as the possibility of losing the nut and increased labor costs.

[0007] In other words, conventional compression connectors required a configuration that improved ease of installation while ensuring secure attachment to the circuit board.

[0008] Therefore, the present invention aims to provide a configuration in which the installation (fixing) of the compression connector is simple when fixing the compression connector to the circuit board, and the compression connector can be fixed to the circuit board with fewer operations. [Means for solving the problem]

[0009] The substrate-mounted connector according to the present invention is a substrate-mounted connector that attaches a compression-type connector to an object to be connected by pressing it against the object to be connected, and comprises a compression connector having contacts that contact the substrate, a housing to which the contacts are fixed, and a cover shell that covers the upper surface of the housing, wherein the cover shell has a vertical surface that is bent perpendicular to the direction of the substrate from the top surface of the cover shell which is arranged parallel to the substrate, and at least one fixing portion is formed on the substrate side of the vertical surface that penetrates a hole formed in the substrate and prevents the compression connector from coming off the substrate.The fixing portion is formed having a flat base portion connected to the substrate side of the vertical surface, an opening connected to the substrate side of the base portion and having an opening hole, and a flat tip portion connected to the substrate side of the opening, and further having a retaining pin inserted into the opening hole of the opening, the retaining pin having a pin tip portion that is bent when inserted into the opening hole, an insertion portion that prevents the compression connector from coming off the substrate when inserted into the opening hole, and a flange portion having a width dimension larger than the diameter of the opening hole. It is characterized by the following:

[0010] In other words, the present invention provides a mechanism for attaching a compression-type connector to a substrate, and by inserting the fixing part into a hole formed in the substrate, a simple and secure fixing state can be obtained.

[0015] Also The retaining pin is inserted into the opening of the fixing part and then bent at the tip to prevent it from coming loose, so it will not fall out or get lost like conventional screws or nuts. In addition, because the fixing mechanism is based on the pin shape of the retaining pin, the amount of work required for installation is reduced, and torque management of screws, as in conventional methods, is not required.

[0016] Furthermore, in the substrate-equipped connector according to the present invention, the compression connector may include a bottom shell that covers the lower surface of the housing. [Effects of the Invention]

[0017] According to the present invention, when fixing the compression connector to the circuit board, the connector attachment (fixing) work is simplified, and a configuration is realized in which the compression connector can be fixed to the circuit board with fewer movements. Therefore, according to the present invention, reliable attachment can be achieved while improving the workability of attaching (fixing) the compression connector to the circuit board.

Modes for Carrying Out the Invention

[0019] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. For the sake of clarity, the drawings define a first direction, a second direction, and a third direction. In this specification, the first direction is the front-back direction. In the drawings, the front-back direction is indicated as the X direction. Specifically, the front is the +X direction and the rear is the -X direction. In this specification, the second direction is the left-right direction. In the drawings, the left-right direction is indicated as the Y direction. Specifically, the right is the +Y direction and the left is the -Y direction. Furthermore, in this specification, the third direction is the up-down direction. In the drawings, the up-down direction is indicated as the Z direction. Specifically, the up is the +Z direction and the down is the -Z direction. However, the first direction (X direction), the second direction (Y direction), and the third direction (Z direction) as defined herein do not limit the direction in which the board-mounted connector of each embodiment can be used. The board-mounted connector of each embodiment can be used in any direction.

[0020] Furthermore, the following embodiments are not intended to limit the invention as described in each claim, and not all combinations of features described in each embodiment are necessarily essential to the solution of the invention.

[0021] [First Embodiment] Referring to Figures 1 to 13, the configuration of the substrate-mounted connector 10 according to the first embodiment will be described. As shown in Figures 1 to 3, the substrate-mounted connector 10 according to the first embodiment includes a substrate 11 and a compression connector 31 attached to the upper surface of the substrate 11.

[0022] The circuit board 11 includes printed circuits (not shown) and is configured to transmit electrical signals, power, etc., by electrically connecting to a compression connector 31 mounted on the top surface of the circuit board 11.

[0023] Furthermore, the substrate 11 has a plurality of holes 12 formed therein, particularly as shown in Figure 3. The compression connector 31 is fixed to the substrate 11 by inserting a plurality of press-fit pins 37 of the compression connector 31, which will be described later, into the plurality of holes 12 (eight in the first embodiment). The plurality of press-fit pins 37 are formed as fixing parts according to the present invention.

[0024] As shown in Figures 7 to 11, the compression connector 31 includes a contact 32 that contacts the substrate 11, a housing 33 to which the contact 32 is fixed, a cover shell 34 that covers the upper surface of the housing 33, and a bottom shell 35 that covers the lower surface of the housing 33.

[0025] Multiple contacts 32 are arranged side-by-side in the left-right direction, particularly as shown in Figures 8 and 9.

[0026] Furthermore, each of the multiple contacts 32 is fixed to the housing 33, as shown in Figure 11, and the front end 32a of the contact 32 is curved to have a spring-elastic shape. In other words, when the compression connector 31 is not in contact with the substrate 11, the front end 32a of the contact 32 is positioned to protrude downward from the bottom surface of the bottom shell 35 (as shown in Figure 11). Therefore, when the bottom surface of the bottom shell 35 constituting the compression connector 31 is pressed against the top surface of the substrate 11 in the -Z direction, the front ends 32a of the multiple contacts 32 that were protruding downward from the bottom surface of the bottom shell 35 are pushed down to the position of the bottom surface of the bottom shell 35 while exerting a spring-elastic force against the top surface of the substrate 11. In other words, the front ends 32a of the multiple contacts 32 are subjected to a force in the +Z direction. Therefore, when the compression connector 31 is attached to the substrate 11, each of the multiple contacts 32 is pressed against the upper surface of the substrate 11 by the force due to spring elasticity, so that, for example, a printed circuit (not shown) placed on the upper surface of the substrate 11 and the multiple contacts 32 can maintain a stable and reliable connection state.

[0027] On the other hand, the rear end 32b of the contact 32 has a straight, linear shape. As shown in Figure 11, an electrical cable 36 is connected to the rear end 32b of the contact 32 by solder or the like. Therefore, external electrical signals and power are transmitted to the substrate 11 side via the electrical cable 36 and the contact 32.

[0028] In the first embodiment, the components constituting the compression connector 31 are such that the multiple contacts 32 are made of a conductive metal material, and the housing 33 that fixes the multiple contacts 32 is made of a non-conductive resin material or the like. Furthermore, the cover shell 34 that covers the upper surface of the housing 33 and the bottom shell 35 that covers the lower surface of the housing 33 are combined vertically with the housing 33 enclosed between them to form the outer shape of the compression connector 31. The cover shell 34 and the bottom shell 35 are arranged to enclose the outer circumference of the housing 33 in which the multiple contacts 32 are embedded, thereby protecting the housing 33 in which the multiple contacts 32 that receive power from the electrical cable 36 are embedded. This protection includes not only physical protection from the external environment, but also electrical and magnetic protection such as electromagnetic shielding.

[0029] The cover shell 34 constituting the compression connector 31 of the first embodiment, as shown in Figure 12, has a top surface 34a arranged parallel to the substrate 11 and a vertical surface 34b that is bent perpendicularly from the top surface 34a of the cover shell 34 toward the substrate 11. In addition, eight press-fit pins 37 are installed on the substrate 11 side of the vertical surface 34b, that is, on the lower side of the vertical surface 34b, passing through a hole 12 formed in the substrate 11 and serving as fixing points to prevent the compression connector 31 from coming loose from the substrate 11.

[0030] In the cover shell 34 of the first embodiment, of the eight press-fit pins 37, six are positioned at approximately equal intervals on the front side of the cover shell 34, one is positioned near the rear right end of the cover shell 34, and one is positioned near the rear left end of the cover shell 34.

[0031] The specific shape of the press-fit pin 37 in the first embodiment is as shown in Figure 13, and it is formed having a flat base portion 37a that is connected to the substrate 11 side of the vertical surface 34b, an opening 37b that is connected to the substrate 11 side of the base portion 37a and has an opening hole 38, and a flat tip portion 37c that is connected to the substrate 11 side of the opening 37b. In the press-fit pin 37 of the first embodiment, the opening 37b is formed with a width dimension that is larger than the base portion 37a and the tip portion 37c, and furthermore, the width dimension of the opening 37b is formed to be larger than the inner diameter of the hole 12 formed in the substrate 11. Therefore, when the press-fit pin 37 is inserted into the hole 12 formed in the substrate 11, the wide opening 37b is located inside the hole 12 in the substrate 11, and the opening 37b is compressed inside the hole 12 in the substrate 11. At this time, due to the wide dimensions of the opening 37b and the action of the opening hole 38, a force acts on the opening 37b to return to its original shape based on the elasticity of the metal material, so a frictional force acts between the opening 37b of the press-fit pin 37 and the hole 12 in the substrate 11. The sum of these frictional forces is greater than the sum of the spring elastic forces exerted by each of the multiple contacts 32 on the upper surface of the substrate 11, so this frictional force holds the compression connector 31 in place so that it does not come out perpendicular to the substrate 11.

[0032] As described above, in the substrate-mounted connector 10 according to the first embodiment, the compression connector 31 can be easily connected to the substrate 11 simply by inserting the press-fit pin 37 into the hole 12 formed in the substrate 11. In other words, the substrate-mounted connector 10 according to the first embodiment simplifies the connector attachment (fixing) work when fixing the compression connector 31 to the substrate 11, and a configuration is realized in which the compression connector 31 can be fixed to the substrate 11 with fewer movements. Therefore, the substrate-mounted connector 10 according to the first embodiment simplifies the workability of attaching (fixing) the compression connector 31 to the substrate 11 while ensuring reliable attachment.

[0033] Although preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the scope described in the first embodiment above. Various modifications or improvements can be made to the first embodiment described above.

[0034] For example, in the first embodiment described above, the case in which eight press-fit pins 37 are used was illustrated, but the number and placement of the press-fit pins 37 as fixing parts of the present invention can be arbitrarily changed. For example, the number of press-fit pins 37 only needs to be one or more, and the placement of the press-fit pins 37 can be any location considering the shape of the compression connector 31 and the substrate 11, etc.

[0035] For example, in the first embodiment described above, when the press-fit pin 37 is inserted into the hole 12 formed in the substrate 11, the wide opening 37b is positioned inside the hole 12 in the substrate 11, and the opening 37b is compressed within the hole 12 in the substrate 11. However, in the present invention, the press-fit pin 37 may also be used to function as a retaining pin. That is, when the press-fit pin 37 is inserted into the hole 12 formed in the substrate 11, the wide opening 37b may pass through the hole 12 in the substrate 11 and exit the inside of the hole 12 to be positioned downwards, so that the wide opening 37b catches on the lower entrance of the hole 12 and exerts a retaining effect.

[0036] The configuration of the substrate-mounted connector 10 according to the first embodiment has been described above with reference to Figures 1 to 13. Next, the substrate-mounted connector 100 according to the second embodiment, which is another possible form of the substrate-mounted connector according to the present invention, will be described with reference to Figures 14 to 25. In the following description, components that are the same as or similar to those described in the first embodiment above may be denoted by the same reference numerals and their descriptions may be omitted.

[0037] [Second Embodiment] Referring to Figures 14 to 25, the configuration of the substrate-mounted connector 100 according to the second embodiment will be described. As shown in Figures 14 to 16, the substrate-mounted connector 100 according to the second embodiment includes a substrate 11 and a compression connector 31 attached to the upper surface of the substrate 11.

[0038] The circuit board 11 includes printed circuits (not shown) and is configured to transmit electrical signals, power, etc., by electrically connecting to a compression connector 31 mounted on the top surface of the circuit board 11.

[0039] Furthermore, the substrate 11 has a plurality of holes 12 formed therein, particularly as shown in Figures 17 to 19. The compression connector 31 is fixed to the substrate 11 by inserting a plurality of fixing legs 137 of the compression connector 31, which will be described later, into the plurality of holes 12 (six in the second embodiment). The plurality of fixing legs 137 are parts formed as fixing parts according to the present invention.

[0040] As shown in Figures 20 to 25, the compression connector 31 includes a contact 32 that contacts the substrate 11, a housing 33 to which the contact 32 is fixed, a cover shell 34 that covers the upper surface of the housing 33, and a bottom shell 35 that covers the lower surface of the housing 33.

[0041] Multiple contacts 32 are arranged side by side in the left-right direction, as shown in Figures 21 and 22.

[0042] Furthermore, each of the multiple contacts 32 is fixed to the housing 33, as shown in Figure 24, and the front end 32a of the contact 32 is curved to have a spring-elastic shape. In other words, when the compression connector 31 is not in contact with the substrate 11, the front end 32a of the contact 32 is positioned to protrude downward from the bottom surface of the bottom shell 35 (as shown in Figure 24). Therefore, when the bottom surface of the bottom shell 35 constituting the compression connector 31 is pressed against the top surface of the substrate 11 in the -Z direction, the front ends 32a of the multiple contacts 32 that were protruding downward from the bottom surface of the bottom shell 35 are pushed down to the position of the bottom surface of the bottom shell 35 while exerting a spring-elastic force against the top surface of the substrate 11. In other words, the front ends 32a of the multiple contacts 32 are subjected to a force in the +Z direction. Therefore, when the compression connector 31 is attached to the substrate 11, each of the multiple contacts 32 is pressed against the upper surface of the substrate 11 by the force due to spring elasticity, so that, for example, a printed circuit (not shown) placed on the upper surface of the substrate 11 and the multiple contacts 32 can maintain a stable and reliable connection state.

[0043] On the other hand, the rear end 32b of the contact 32 has a straight, linear shape. As shown in Figure 24, an electrical cable 36 is connected to the rear end 32b of the contact 32 by solder or the like. Therefore, external electrical signals and power are transmitted to the substrate 11 side via the electrical cable 36 and the contact 32.

[0044] In the second embodiment, the components constituting the compression connector 31 are such that the multiple contacts 32 are made of a conductive metal material, and the housing 33 that fixes the multiple contacts 32 is made of a non-conductive resin material or the like. Furthermore, the cover shell 34 that covers the upper surface of the housing 33 and the bottom shell 35 that covers the lower surface of the housing 33 are combined vertically with the housing 33 enclosed between them to form the outer shape of the compression connector 31. The cover shell 34 and the bottom shell 35 are arranged to enclose the outer circumference of the housing 33 in which the multiple contacts 32 are embedded, thereby protecting the housing 33 in which the multiple contacts 32 that receive power from the electrical cable 36 are embedded. This protection includes not only physical protection from the external environment, but also electrical and magnetic protection such as electromagnetic shielding.

[0045] The cover shell 34 constituting the compression connector 31 of the second embodiment, as shown in Figures 20 to 25, has a top surface 34a arranged parallel to the substrate 11 and a vertical surface 34b that is bent perpendicularly from the top surface 34a of the cover shell 34 toward the substrate 11. Furthermore, on the substrate 11 side of the vertical surface 34b, i.e., the lower side of the vertical surface 34b, six fixing legs 137 are installed as fixing parts that penetrate the hole 12 formed in the substrate 11 and prevent the compression connector 31 from coming off the substrate 11.

[0046] In the cover shell 34 of the second embodiment, three of the six fixed legs 137 are arranged at approximately equal intervals on the front side of the cover shell 34, and three are arranged at approximately equal intervals on the rear side of the cover shell 34. Furthermore, in the second embodiment, the fixed legs 137 arranged on the front side and the fixed legs 137 arranged on the rear side are arranged to overlap when viewed from the front, and the two front and rear fixed legs 137 form a pair, forming a total of three pairs of fixed legs 137.

[0047] Furthermore, the specific shape of the fixed leg portion 137 in the second embodiment is as shown in Figures 20 to 25, and it is formed having a flat base portion 137a that is connected to the substrate 11 side of the vertical surface 34b, an opening 137b that is connected to the substrate 11 side of the base portion 137a and has an opening hole 138, and a flat tip portion 137c that is connected to the substrate 11 side of the opening 137b. In the substrate-mounted connector 100 of the second embodiment, a retaining pin 140 is provided that can be inserted into the opening hole 138 of the opening 137b formed in the fixed leg portion 137.

[0048] The retaining pin 140 of the second embodiment, as shown in Figures 17 to 19, is configured to have a pin tip portion 140a that is bent when inserted into the opening hole 138, an insertion portion 140b that prevents the compression connector 31 from coming loose from the substrate 11 when inserted into the opening hole 138, and a flange portion 140c having a width dimension larger than the diameter of the opening hole 138. Although Figures 16 to 19 and 25 depict the pin tip portion 140a already bent, the pin tip portion 140a of the retaining pin 140 before installation is straight in the front-rear direction, similar to the insertion portion 140b.

[0049] Next, the installation method of the substrate-equipped connector 100 according to the second embodiment will be described. Starting from the state shown in Figures 17 to 19, first insert the fixing legs 137 of the compression connector 31 into the holes 12 of the substrate 11. From this state, insert the three retaining pins 140 into the openings 138 formed in the openings 137b of the fixing legs 137. As described above, the six fixing legs 137 of the compression connector 31 in the second embodiment form a total of three pairs of fixing legs 137, with the fixing legs 137 positioned on the front side and the fixing legs 137 positioned on the rear side overlapping in a front view. Therefore, there are also three pairs of openings 138 formed in the openings 137b of the six fixing legs 137. Then, insert the three retaining pins 140 into each of the three pairs of openings 138. In this case, the retaining pin 140 is inserted into the opening 138 with its tip portion 137c facing from the rear to the front. When the flange portion 140c of the retaining pin 140 is inserted until it contacts the opening 138 of the fixing leg portion 137 located on the rear side, as shown in Figure 25, the insertion portion 140b of the retaining pin 140 is stretched over a pair of openings 138 that are arranged in overlapping positions when viewed from the front, and the pin tip portion 140a of the retaining pin 140 penetrates forward through the opening 138 of the opening 137b formed in the fixing leg portion 137 on the front side. By bending the pin tip portion 140a of the retaining pin 140 downwards in this state, the installation state shown in Figure 25 is completed.

[0050] When the installation state shown in Figure 25 is completed, the spring elastic force exerted by each of the multiple contacts 32 on the upper surface of the substrate 11 causes a force acting between the substrate 11 and the compression connector 31 in a direction that separates them from each other. However, since retaining pins 140 are installed on the fixing legs 137 of the compression connector 31 so as to sandwich the substrate 11, these retaining pins 140 receive the spring elastic force, thereby holding the compression connector 31 in place so as not to come off perpendicular to the substrate 11.

[0051] As described above, in the substrate-mounted connector 100 according to the second embodiment, the compression connector 31 can be easily connected to the substrate 11 by simply inserting the fixing leg portion 137 into the hole 12 formed in the substrate 11, and then inserting the retaining pin 140 into the opening hole 138 formed in the fixing leg portion 137 to secure it. Furthermore, the retaining pin 140 in the second embodiment is secured by bending the pin tip portion 140a after insertion into the opening hole 138 of the opening 137b of the fixing leg portion 137, so it does not fall out or get lost like conventional screws or nuts. Moreover, because the fixing mechanism is based on the pin shape of the retaining pin 140, the amount of work required for installation is reduced, and torque management of screws, as in the conventional method, is not required.

[0052] In other words, according to the second embodiment of the substrate-mounted connector 100, when fixing the compression connector 31 to the substrate 11, the connector installation (fixing) work is simple, and a configuration is realized in which the compression connector 31 can be fixed to the substrate 11 with fewer movements. Therefore, according to the second embodiment of the substrate-mounted connector 100, reliable attachment can be achieved while improving the workability of attaching (fixing) the compression connector 31 to the substrate 11.

[0053] Although preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the scope described in the second embodiment above. Various modifications or improvements can be made to the second embodiment described above.

[0054] For example, in the second embodiment described above, for the openings 138 formed in the openings 137b of the six fixed legs 137, three sets of two openings 138 are provided, and three retaining pins 140 are inserted into each of these three pairs of openings 138. However, the number and placement of the fixed legs 137 and retaining pins 140 as fixing parts of the present invention, as well as the method of combining them, can be arbitrarily changed.

[0055] It is clear from the claims that such modified or improved forms may also fall within the technical scope of the present invention. [Explanation of Symbols]
