Description

Technical Field

[0001] The technology disclosed in this specification relates to coaxial connectors. Background Technology

[0002] As an example of a coaxial connector, Patent Document 1 discloses a coaxial connector having an outer housing (shell) and a retainer. The outer housing has a terminal receiving chamber (terminal receiving portion) that receives a socket (terminal) connected to the end of a coaxial cable. The retainer is fitted to the outer housing, locking the socket within the terminal receiving chamber (preventing detachment). The socket has a flange protruding outwards from the outer periphery of an external contact. The outer housing has a housing spear-shaped portion that prevents the flange of the terminal received inside the terminal receiving chamber from detaching. The retainer has a locking claw (abutment portion) formed to freely insert into a locking hole (retainer insertion hole) formed in the outer housing, preventing the flange from detaching.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2019-153464 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] For example, in coaxial connectors used in applications where external force is applied to the cable, such as in vehicle doors, the terminals housed within the housing may rotate, causing the terminal contacts to rub against each other and wear. To reduce this, a stop (anti-rotation) is sometimes installed in the housing to limit terminal rotation. In coaxial connectors where the housing has a stop in addition to a retainer to hold the terminals in their proper position to prevent detachment, the number of components and assembly steps increases. Furthermore, forming multiple insertion holes in the housing may reduce strength and decrease the design flexibility of the connector.

[0008] The technology disclosed in this specification is based on the above-described circumstances and aims to provide a simple coaxial connector that can limit the rotation of terminals housed in the terminal housing and keep them in the correct position.

[0009] Solution for solving the problem

[0010] The coaxial connector disclosed in this specification comprises: a housing having a terminal receiving portion inside, wherein a terminal for connection to a coaxial cable is inserted from the rear of the terminal receiving portion; and a retainer mounted on the housing. The terminal has: a crimp portion formed by crimping in a polygonal manner on the outer periphery of its cross-section; and a flange portion formed such that, when the terminal is inserted into the terminal receiving portion, it is located in front of the crimp portion in the insertion direction of the terminal and protrudes outwardly from the crimp portion. A retainer insertion hole is formed in the housing. The retainer has a fitting portion, an abutment portion, and a recess portion that penetrate the wall of the terminal receiving portion in a direction intersecting the insertion direction of the terminal. When the terminal is received in the proper position of the terminal receiving portion and the retainer is inserted from the retainer insertion hole and installed in the locking position, the fitting portion fits into the outer periphery of the crimping portion of the terminal, including at least one corner portion. The abutment portion abuts against the flange portion of the terminal from the rear. The recess portion causes the fitting portion to retract towards the outer periphery of the terminal between the fitting portion and the abutment portion.

[0011] Invention Effects

[0012] According to this disclosure, a simple coaxial connector can be provided that can limit the rotation of terminals housed in the terminal housing and keep them in the correct position. Attached Figure Description

[0024] [Description of embodiments of this disclosure]

[0025] First, the implementation methods of this disclosure are listed and explained.

[0026] (1) The coaxial connector of this disclosure comprises: a housing having a terminal receiving portion therein, wherein a terminal for connection with a coaxial cable is inserted from the rear into the terminal receiving portion; and a retainer mounted on the housing, wherein the terminal has: a crimp portion formed by crimping in a polygonal manner on the outer periphery of its cross-section; and a flange portion formed such that, when the terminal is inserted into the terminal receiving portion, it is located in front of the insertion direction of the terminal in the crimp portion and protrudes in a direction further outward than the crimp portion; a retainer insertion hole is formed in the housing, the retainer insertion hole... The retainer has a fitting portion, an abutment portion, and a recess portion that penetrate the wall of the terminal receiving portion in a direction intersecting the insertion direction of the terminal. When the terminal is received in the proper position of the terminal receiving portion and the retainer is inserted from the retainer insertion hole and installed in the locking position, the fitting portion fits into the outer periphery of the crimping portion of the terminal, including at least one corner portion. The abutment portion abuts against the flange portion of the terminal from the rear. The recess portion causes the fitting portion to retract towards the outer periphery of the terminal between the fitting portion and the abutment portion.

[0027] According to the structure described in (1) above, the engagement portion functions as an anti-rotation portion, thereby limiting the rotation of the terminal, and the abutment portion functions as an anti-detachment portion, thereby limiting rearward detachment. Since the retainer combines both the engagement portion and the abutment portion, terminal anti-detachment and anti-rotation can be achieved simply by installing the retainer. Here, in a terminal where a crimping portion is formed by fastening the rear side of the flange portion of a terminal part embedded around the coaxial cable, an incomplete crimping portion with a diameter larger than the diameter of the crimping portion is formed between the flange portion and the crimping portion. In this respect, in the above structure, a recess is provided between the abutment portion and the engagement portion of the retainer, and this recess functions as a retraction portion of the incomplete crimping portion, allowing the engagement portion to engage with the outer periphery of the crimping portion without interfering with the incomplete crimping portion. As a result, with a simple structure, rotation can be limited in the coaxial connector and the terminal can be held in the correct position of the terminal receiving portion.

[0028] (2) In the coaxial connector of this disclosure, preferably, the end of the retainer in the abutment portion on the insertion direction side of the retainer has an inclined portion that tilts backward toward the insertion direction.

[0029] When the retainer is inserted into the retainer insertion hole with the terminal in a semi-inserted position, which is further back than the normal position within the terminal storage section, the insertion end of the first contact portion abuts against the radially protruding flange portion. According to the structure described in (2), by providing a rearwardly inclined portion at this end, when the retainer is further pressed in, the flange portion is pressed forward by the inclined portion, and the terminal moves to the normal position. Thus, simply inserting the retainer and pressing it into the locking position allows the terminal in the semi-inserted position to be moved and stored in the normal position.

[0030] (3) In the coaxial connector of this disclosure, preferably, the retainer is formed in a structure that is symmetrical about the front-to-back center plane when assembled with the housing.

[0031] According to the structure described in (3) above, installation can be performed without considering the front and back of the retainer, thus improving work efficiency. In addition, it is applicable to both male and female coaxial connectors that house the male and female terminals that are connected face to face, thus enabling component sharing and simplifying component management.

[0032] [Details of the embodiments of this disclosure]

[0033] The following describes embodiments of this disclosure. The invention is not limited to these examples, but is intended to include all modifications within the meaning and scope of the claims, as shown by the claims themselves.

[0034] <Implementation Method>

[0035] While referring to Figures 1 to 11 The implementation method will be explained.

[0036] In this disclosure, the coaxial connector is positioned opposite to the other party's coaxial connector, i.e., on the opposite side. Figure 3 For the coaxial connector shown Figure 3 The left side is set as front (and the opposite side as back). For convenience, in the following explanation, Figure 3 The upper side is designated as "up" (and the opposite side as "down"), but the coaxial connector and connector structure can be used in any orientation. Regarding the retainer, the description is based on its orientation when assembled into the housing. Additionally, the direction in which the retainer is inserted into the housing (from top to bottom) is sometimes referred to as the insertion direction. In addition to... Figure 4 , 5 A portion of the accompanying figures, excluding those shown elsewhere, illustrates the X, Y, and Z axes of an orthogonal coordinate system XYZ, drawn such that each axis direction is the same across all figures. The Z-axis represents the vertical direction, the Y-axis represents the horizontal direction, and the X-axis represents the left-right direction. Furthermore, regarding multiple identical components, sometimes only one component is labeled with a reference numeral, while the reference numerals for the other components are omitted.

[0037] (Connector structure)

[0038] Figure 1 and Figure 2 This diagram shows a connector structure 100 comprising the coaxial connector 1 of this embodiment. The connector structure 100 is formed by fitting a male coaxial connector 1 and a female coaxial connector 2 together. The coaxial connector 1 houses a male terminal T100 that connects to the end of a coaxial cable C1, and the coaxial connector 2 houses a female terminal T200 that connects to the end of a coaxial cable C2. Figure 2 As shown, the male coaxial connector 1 includes a male housing 10 and a retainer 50 mounted on the housing 10. The housing 10 has a cylindrical cover 13 protruding forward. The female coaxial connector 2 includes a female housing 20 and a retainer 50 mounted on the housing 20. The housing 20 has a fitting sleeve at its front for the cover 13 to be inserted into. Furthermore, although not shown, the connector structure 100 further includes a male frame for retaining the male coaxial connector 1 and a female frame for retaining the female coaxial connector 2. A locking structure provided on the male and female frames can maintain the two coaxial connectors 1 and 2 in a mating state.

[0039] like Figure 2 As shown, in the connector structure 100, the retainer 50 mounted on the male housing 10 and the retainer 50 mounted on the female housing 20 have the same structure, and the components can be shared. The following mainly describes the male coaxial connector 1.

[0040] (case)

[0041] Figure 3 This is a partially cut-away side view of coaxial connector 1. (See attached image.) Figure 2 and Figure 3 As shown, the housing 10 of the coaxial connector 1 has a generally cylindrical cover 13 that protrudes forward from the front surface of the generally cuboid male-side main body 11. The housing 10 can be constructed, for example, using an insulating synthetic resin integrally molded. Figure 3 As shown, a terminal housing 15 is formed inside the housing 10, and the terminal housing 15 extends through the male side main body 11 and the cover 13 in the front-rear direction. The terminal housing 15 houses the terminal T100, which is inserted from the rear and connected to the end of the coaxial cable C1.

[0042] like Figure 3 As shown, a spear-shaped portion 17 is formed on the lower surface of the male-side main body 11, protruding into the interior of the terminal storage portion 15 in its natural state. The spear-shaped portion 17 is formed as a cantilever with its front end as the free end, and can be flexed and deformed in the upward and downward directions. Additionally, a retainer insertion hole 19 is formed on the upper surface of the male-side main body 11, penetrating the upper wall of the terminal storage portion 15. A pair of retainer locking holes 18 are formed on the side of the retainer insertion hole 19 in the male-side main body 11, penetrating the left and right walls of the terminal storage portion 15 (see reference). Figure 10 ).

[0043] (coaxial cable)

[0044] Coaxial cables C1 and C2 can, for example, be coaxial cables having an inner conductor, a dielectric material disposed around the outer periphery of the inner conductor, an outer conductor disposed around the outer periphery of the dielectric material and composed of braided wire or the like, and an insulator covering the outer periphery of the outer conductor. The coaxial terminal connected to the terminated coaxial cable is configured, for example, to have a center contact connected to the inner conductor, an insulator holding the center contact, an outer contact holding the insulator, and a metal sleeve pressed against the outer conductor.

[0045] (terminal)

[0046] Figure 4 The male terminal T100 housed in the coaxial connector 1 is shown. Figure 5 The female terminal T200 housed in the coaxial connector 2 is shown.

[0047] Terminals T100 and T200 each have: crimping portions T111 and T211, which are crimped to coaxial cables C1 and C2 at their base ends; cylindrical top portions T121 and T221, which are connected to the opposite terminal at their top ends; and flange portions T131 and T231, which are located in front of the crimping portions T111 and T211 and protrude outward in a peripheral direction. Front flange portions T132 and T232, which protrude between the flange portions T131 and T231 and the top portions T121 and T221, have an outer diameter approximately the same as that of the flange portions T131 and T231.

[0048] The tip portion T221 of the female terminal T200 is formed in such a way that it fits approximately tightly against the outer periphery of the tip portion T121 of the male terminal T100. When the coaxial connector 1, in its normal position, houses the male terminal T100, and the coaxial connector 2, in its normal position, are engaged, the tip portion T121 of the male terminal T100 is inserted into the tip portion T221 of the female terminal T200, for example, the center contacts inside the tip portions T121 and T221 abut against each other, thereby electrically connecting the two terminals T100 and T200.

[0049] The crimping portions T111 and T211 are crimped onto the coaxial cables C1 and C2 in a polygonal cross-section by securing the rear sides of the flange portions T131 and T231 after the terminal parts are embedded into the outer periphery of the coaxial cables C1 and C2 that have undergone end treatment. In this embodiment, a case where the crimping portion has a hexagonal cross-section is illustrated. In this embodiment, the crimping portion T111 of the male terminal T100 and the crimping portion T211 of the female terminal T200 are formed with the same shape.

[0050] When the crimped portions T111 and T211 are fastened as described above, it is difficult to crimp the terminals to the boundary limits of the flange portions T131 and T231. Therefore, as Figure 4 and Figure 5 As shown, in the two end pieces T100 and T200, there are partially crimped portions T141 and T241 formed between the flange portions T131 and T231 and the crimped portions T111 and T211. These portions have a smaller diameter than the flange portions T131 and T231 but a larger diameter than the crimped portions T111 and T211.

[0051] (Maintaining the body)

[0052] Figures 6 to 8 The holder 50 is shown, which is installed in the male housing 10 and the female housing 20. Figures 6 to 8 The hollow arrow in the diagram indicates the insertion direction of retainer 50. For example... Figure 6As shown, the retainer 50 has: a main body 51; a pair of legs 53 that protrude downwards from the main body 51 toward the insertion direction of the retainer 50; a pair of flexible arms 55 that can be cantilevered to the left and right of the main body 51, with the lower end being the free end; and a pair of waists 57 that protrude to the left and right from the main body 51 below the lower end of the arms 55. In the arms 55, a locking claw 55A protruding to the left and right is formed at the lower end, which is the free end. Figure 7 As shown, the upper surface of the locking claw 55A is formed as a roughly horizontal plane, and the lower surface is formed as an inclined surface that extends outward in an upward direction.

[0053] like Figure 8 As shown, the main body 51, leg 53, and waist 57 are formed with their front surfaces substantially flush. This front surface is the abutment portion 50A, which, as described later, abuts against the rear surface of the flange portion T131 of the terminal T100, which is housed in its normal position, when the retainer 50 is installed in the locked position (see reference). Figure 9B ).

[0054] like Figure 6 and Figure 7 As shown, a fitting portion 53A is formed on the lower surface of the retainer 50 between a pair of legs 53 on the insertion side. The fitting portion 53A has a shape that fits substantially tightly with the outer periphery of the press-fit portion T111, including at least one corner. Additionally, as... Figure 6 and Figure 8 As shown, a recess 53B is formed on the front side of the fitting portion 53A by cutting it backward toward the outer periphery of the terminal T100 while the fitting portion 53A is fitted with the outer periphery of the crimping portion T111. The recess 53B is formed such that its front-rear dimension is approximately equal to or slightly larger than the dimension from the rear surface of the flange portion T131 to the front end of the crimping portion T111. Furthermore, the depth of the recess 53B is larger than the height from the outer peripheral surface of the crimping portion T111 to the outer peripheral surface of the partially crimped portion T141, and is approximately equal to or less than the height from the outer peripheral surface of the crimping portion T111 to the outer peripheral surface of the flange portion T131. Further as... Figure 6 and Figure 8 As shown, an inclined portion 53C is formed on the front surface of the protruding end of the leg portion 53, i.e., the end on the insertion direction side of the abutment portion 50A. It is inclined backward as it faces downward.

[0055] In addition, maintaining body 50 is formed as about Figure 8 The structure shown is symmetrical to the central plane P in the front-rear direction. That is, the rear surface of the retainer 50 is also formed in a manner consistent with... Figure 7 The front surface shown has the same shape.

[0056] (Installation of the retainer)

[0057] Then, while referring to Figures 9A to 11 The situation where the retainer 50 is installed in the locking position of the housing 10 will be explained.

[0058] Figure 9A This diagram illustrates the situation where the terminal T100, inserted from the rear into the terminal receiving portion 15, is in a semi-inserted position (not yet in its proper position), and the retainer 50 is inserted through the retainer insertion hole 19. In this state, the spear-shaped portion 17 on the lower surface of the housing 10 abuts against the flange portion T131 and flexes downwards. Figure 9A As indicated by the hollow arrow, the retainer 50 is inserted downward from the leg 53 while the abutment portion 50A of its front surface runs along the opening edge of the retainer insertion hole 19. When the protruding end of the leg 53 enters the interior of the terminal receiving portion 15, firstly, the inclined portion 53C formed on the front surface of the protruding end of the leg 53 abuts against the rear surface corner of the flange portion T131 of the terminal T100, which is in the half-insertion position. As the retainer 50 is pressed in in this manner, it moves downward as the retainer 50 moves downward. Figure 9A As indicated by the black arrow, the flange T131 is pressed forward by the inclined portion 53C, and the terminal T100 moves to the correct position.

[0059] like Figure 9B As shown, when the retainer 50 is pressed in and installed in the locked position, the flange T131 also moves forward of the front end of the spear-shaped portion 17. The spear-shaped portion 17 is released from its spring compression and returns to its original deformation, located behind the flange T131, thereby restricting the rearward movement of the flange T131 and consequently the terminal T100. Simultaneously, the abutment portion 50A on the front surface of the retainer 50 abuts against the rear surface of the flange T131, thus the abutment portion 50A functions as an anti-disengagement part, doubly restricting the rearward movement of the terminal T100.

[0060] like Figure 10 As shown, the locking position is where the waist portion 57 of the retainer 50 is pressed in until it abuts against the lower opening edge of the retainer locking hole 18. When the retainer 50 is pressed in to the locking position, it deforms and flexes towards the central axis while restoring its deformation through the arm portion 55 of the retainer insertion hole 19, and the upper surface of the locking claw 55A abuts against the upper opening edge of the retainer locking hole 18. Thus, the retainer 50 is prevented from detaching upwards and is locked into the housing 10.

[0061] Figure 11 It is installed at Figure 3 A magnified view of the vicinity of the retaining body 50 at the shown locking position. (See attached image.) Figure 10 and Figure 11As shown, when the retainer 50 is installed in the locked position, the fitting portion 53A formed on the lower surface between the pair of legs 53 fits substantially tightly with the outer periphery of the crimping portion T111 of the terminal T100. By fitting the fitting portion 53A with the outer periphery of the crimping portion T111, including at least one corner, the fitting portion 53A functions as an anti-rotation portion (stop portion), suppressing the rotation of the terminal T100 when an external force is applied to the coaxial cable C1.

[0062] At this time, as Figure 11 As shown, in the retainer 50, the recess 53B is positioned opposite to the incomplete crimping portion T141 formed between the flange portion T131 and the crimping portion T111 of the terminal T100. By having the recess 53B function as a retraction portion of the incomplete crimping portion T141, the retainer 50 can be pressed into the locking position without interference between the incomplete crimping portion T141 and the fitting portion 53A.

[0063] (Effects of the implementation method)

[0064] Next, the effects of this embodiment will be explained.

[0065] The coaxial connector 1 of this embodiment includes: a housing 10, in which a terminal receiving portion 15 is provided, the terminal receiving portion 15 being inserted from the rear into a terminal T100 connected to a coaxial cable C1; and a retainer 50, mounted on the housing 10. The terminal T100 has: a crimping portion T111, which is formed by crimping in a polygonal manner on its outer periphery; and a flange portion T131, which is formed such that it is located in front of the crimping portion T111 and protrudes outward from the crimping portion T111 when the terminal T100 is inserted into the terminal receiving portion 15. A retainer insertion hole 19 is formed in the housing 10, and the retainer insertion hole 19 is used to connect the terminal T100 to the terminal T100. The direction of the insertion direction of 00 intersects the wall of the terminal receiving part 15. The retainer 50 has a fitting part 53A, an abutment part 50A and a recess 53B. When the terminal T100 is stored in the terminal receiving part 15 in the normal position and the retainer 50 is inserted from the retainer insertion hole 19 and installed in the locking position, the fitting part 53A fits with the outer periphery of the crimping part T111 of the terminal T100, including at least one corner. The abutment part 50A abuts with the flange part T131 of the terminal T100 from the rear. The recess 53B causes the fitting part 53A to retract toward the outer periphery of the terminal T100 between the fitting part 53A and the abutment part 50A.

[0066] According to the coaxial connector 1 of this embodiment, the fitting portion 53A functions as an anti-rotation portion, thereby limiting the rotation of the terminal T100, and the abutment portion 50A functions as an anti-detachment portion, thereby preventing the terminal T100 from detaching rearward. Since the retaining body 50 combines the fitting portion 53A and the abutment portion 50A, simply installing the retaining body 50 is sufficient to prevent the terminal T100 from detaching and from rotating. Here, in terminals where a crimping portion T111 is formed by fastening the rear side of the flange portion T131 of the terminal part embedded around the coaxial cable C1, in order to prevent wire breakage in the crimping portion T111, crimping is performed while gradually reducing the compressive stress of the coaxial cable C1 towards the boundary portion with the flange portion T131. Therefore, an incomplete crimping portion T141 (so-called a bell mouth) with a diameter larger than the diameter of the crimping portion T111 is formed between the flange portion T131 and the crimping portion T111. In this respect, in the above structure, a recess 53B is provided between the abutment portion 50A and the fitting portion 53A of the retaining body 50. The recess 53B functions as a retraction portion of the incomplete crimping portion T141, thereby allowing the fitting portion 53A to engage with the outer periphery of the crimping portion T111 without interfering with the incomplete crimping portion T141. As a result, a coaxial connector 1 with a simple structure can be provided that can limit rotation and hold the terminal T100 in the correct position of the terminal receiving portion 15.

[0067] Furthermore, in the coaxial connector 1 of this embodiment, the retainer 50 has a pair of legs 53 that protrude in a forked shape toward the insertion direction of the retainer 50 toward the housing 10. An abutment portion 50A is formed on the front surface of the legs 53, and a fitting portion 53A is formed on the side between the pairs of legs 53 in the insertion direction. The front side of the fitting portion 53A is cut to form a recess 53B in a manner that moves backward toward the outer periphery of the terminal T100.

[0068] Furthermore, in the coaxial connector 1 of this embodiment, the end of the retainer 50 in the abutment portion 50A on the insertion direction side has an inclined portion 53C that tilts backward as it moves toward the insertion direction.

[0069] When the retainer 50 is inserted into the retainer insertion hole 19 with the terminal T100 in a semi-inserted position (rear of its normal position), the insertion end of the abutment portion 50A first abuts against the radially protruding flange portion T131. According to the coaxial connector 1 of this embodiment, by providing a rearwardly inclined portion 53C at this end, when the retainer 50 is further pressed in, the flange portion T131 is pressed forward by the inclined portion 53C, and the terminal T100 moves to the forward normal position. Thus, by simply inserting the retainer 50 and pressing it into the locking position, the terminal T100, located in the semi-inserted position, can be moved and stored in the normal position.

[0070] Furthermore, in the coaxial connector 1 of this embodiment, the retainer 50 is formed with a structure symmetrical about the front-rear center plane P when assembled into the housing 10.

[0071] With this coaxial connector 1, installation can be performed without considering the front and back of the retaining body 50, thus improving work efficiency. Furthermore, it is applicable to both male and female coaxial connectors 1 and 2, which house the male-type terminal T100 and female-type terminal T200 respectively, allowing for component sharing and simplifying component management.

[0072] <Other Implementation Methods>

[0073] This disclosure is not limited to the embodiments described above and the accompanying drawings. For example, the following embodiments are also included in the technical scope of the technology disclosed in this specification.

[0074] (1) In the above embodiment, it is described as a coaxial connector housing a single terminal, but it is not limited thereto. In a coaxial connector in which a retainer is fitted into a housing housing housing multiple terminals, multiple abutment portions (anti-disengagement portions), fitting portions (anti-rotation portions), and recesses (retraction portions) are respectively provided in the retainer, thereby enabling multiple terminals to be prevented from disengaging and to be prevented from rotating.

[0075] (2) The housing described in the above embodiments is merely one example, and these can also be formed in different shapes. The coaxial connector is not limited to a connector structure having male and female connectors.
