CONNECTOR PART ASSEMBLY, CONNECTOR PART AND ELECTRONIC DEVICE

Description

[0001] The invention relates to an assembly of a connector part. Furthermore, the invention relates to such a connector part and an electronic device.

[0002] Retaining frames of such assemblies serve for the modular use and retention of contact inserts on connector parts. One or more contact inserts can be arranged on such a retaining frame, which can be inserted into a housing or a housing part of the housing of a connector part together with the retaining frame and connected to the housing or the housing part. In this way, contact inserts can be combined with one another in a modular manner and arranged in or on a connector part via the retaining frame.

[0003] Such contact inserts can, for example, have one or more electrical contacts. In this case, the contact inserts are connected to electrical wires fed into a connector, on the one hand, and form plug contacts, via which the connector can be plugged into a mating connector part to make electrical contact.

[0004] Such modular contact inserts offer the advantage of flexible combination and thus variable application of connectors.

[0005] In a holding frame known from DE 10 2012 110 907 A1, it is provided that a second holding frame part can be attached to a first holding frame part, which has recesses for receiving projection elements of the contact inserts, in order to block projection elements lying in the recesses and thus to lock them to the holding frame.

[0006] In a fastening insert for a connector known from DE 20 2005 007 221 U1, a mounting frame on which a contact insert is arranged can be inserted into a receiving opening of a device housing for fixation. The mounting frame is made at least partially of an electrically conductive material to establish an electrically conductive connection between the contact insert and the device housing. In an inserted position, the mounting frame is locked to the device housing via a plurality of locking elements.

[0007] DE 10 2015 118 263 A1 discloses an assembly according to the preamble of claim 1.

[0008] Traditionally, a retaining frame for accommodating modular contact inserts is often screwed to a housing part into which the retaining frame is to be inserted. While this ensures a mechanically strong, reliably durable connection, it requires a comparatively complex assembly process because, in order to connect the retaining frame to a corresponding housing part, the retaining frame must first be inserted into the housing part and then screwed to the housing part.

[0009] The invention is based on the object of providing an assembly, a connector part and an electronic device in which the connection of a holding frame to a housing part can be simplified.

[0010] The object is achieved according to the invention with the features of the independent claims. Expedient embodiments and advantageous further developments of the invention are specified in the subclaims.

[0011] The assembly according to the invention comprises a holding frame having a receiving space for receiving at least one contact insert and having at least one flange portion. Furthermore, the assembly comprises a housing part having a receiving opening into which the holding frame can be inserted in an insertion direction, and the housing part has at least one support portion formed in the receiving opening. Furthermore, at least one locking element is provided, which is arranged on the holding frame, wherein the locking element engages with the housing part in an inserted position in order to lock the holding frame to the housing part.In addition, at least one spring element is provided which is arranged on the at least one flange section and which, in the inserted position, rests on the at least one support section to form an electrical contact between the holding frame and the housing part and is transferred into a tensioned state.

[0012] According to the invention, at least one spring element is now provided for the mechanical and electrical connection of the holding frame to the housing part, and thus no longer a screw connection. The spring element is characterized by elastic behavior. The spring element is preferably made of an electrically conductive material, such as a metal. When the holding frame is inserted into the housing part, the at least one spring element can initially be tensioned before the actual fastening, in particular locking, of the holding frame to the housing part via the locking element can take place. This enables direct locking of the holding frame to the housing part. When the holding frame is inserted into the receiving opening of the housing part, a positive connection between the holding frame and the housing part can be established via the locking element.The locking element can be designed such that when the holding frame is inserted into the receiving opening of the housing part, the locking between the holding frame and the housing part is established automatically. However, a non-automatic locking, such as a manual locking, is also possible. Through a particularly positive engagement of the locking element on the housing part, a secure, reliable connection can be created between the holding frame and the housing part, which can be easily released by unlocking the locking element. The creation of screw connections can thus be eliminated, so that the connection between the holding frame and the housing part can be established in a simple manner.To connect the holding frame to the housing part, the holding frame is inserted into the receiving opening of the housing part along an insertion direction so that the holding frame, with the at least one spring element arranged on the at least one flange section, can come into contact with one or more support sections of the housing part. In the inserted position, the holding frame thus rests on the one or more support sections so that the holding frame, viewed axially along the insertion direction, can reach a defined position within the housing part. The housing part can be made of a metal, so that the housing part can be, for example, a zinc die-cast part or an aluminum die-cast part.The housing part can also be formed only partially from a metal and partially from a plastic material, in which case, in particular in the region of the at least one support section, a metal material is provided, which, in the inserted position, makes electrical contact with the spring element resting on the support section and arranged on the flange section of the holding frame. Due to the tensioned state of the spring element in this contacting position with the support section, a secure contact can be established between the holding frame and the housing part at all times, since relative movements between the housing part and the holding frame can be compensated for in the inserted position via the spring element.In addition, the mechanical locking of the holding frame to the housing part can also be improved by the at least one spring element, since the clamping force of the at least one spring element can bring the locking element into particularly secure engagement with the housing part, in particular by pressing it. The holding frame preferably has two flange sections, with two spring elements and one locking element preferably arranged on each flange section. The housing part then has four support sections, on each of which one of the four spring elements rests in the inserted position.

[0013] The spring element preferably has a free end section which, in a relaxed state of the spring element, can extend at an angle of 10° ≤ α ≤ 40° to the flange section of the holding frame. The free end section of the spring element can thus extend, in a relaxed and thus non-tensioned state, at an angle to the flange section to which the spring element is arranged or fastened. Due to this angular arrangement of the free end section of the spring element, the spring element can be tensioned when the holding frame is inserted into the housing part and thus when the spring element strikes the support section of the housing part. If, when the holding frame is inserted into the housing part, the spring element strikes the support section with its free end section, this free end section pivots in the direction of the flange section, whereby tension can be generated in the spring element.In the tensioned state, the free end section of the spring element is preferably aligned parallel to the flange section of the holding frame. The free end section can be designed in the form of a spring tab or a leg. The free end section can be connected to a fastening section of the spring element, wherein the spring element can be held and fastened to the flange section of the holding frame via its fastening section. The fastening section can, for example, be U-shaped, so that the spring element can engage around the flange section of the holding frame with its fastening section. Both the free end section and the fastening section are preferably flat.

[0014] The spring element can be bent in an S-shape. The free end section can form an S-shape together with the fastening section. This S-shape allows for a compact design of the spring element while maintaining good spring properties.

[0015] For example, the spring element can be a stamped and bent part, which allows for reduced-cost production. The spring element can be punched from a sheet metal strip and bent into the desired shape, in particular to form the free end section and the fastening section.

[0016] Preferably, the spring element is made of a spring-elastic, electrically conductive material.

[0017] The spring element can be attached to the flange section by means of a snap-in connection. For example, a snap-in tab or locking lug can be formed on the spring element, which can engage in a recess or opening formed in the flange section. The snap-in tab or locking lug can be formed on the fastening section of the spring element. The snap-in connection enables simple installation of the spring element on the support frame. Furthermore, the spring element can be easily removed and replaced.

[0018] At least one recess is preferably formed on the housing part, into which the locking element can engage at least partially in the inserted position. The locking element can engage in a form-fitting manner with at least a partial region of the locking element. When the holding frame is inserted into the housing part in the insertion direction, the locking element can automatically snap into the recess in the housing part, whereby a latching connection can be formed between the holding frame and the housing part. The number of recesses on the housing part preferably corresponds to the number of locking elements, so that each locking element can be assigned a recess. The one or more recesses are preferably formed on one or both end walls of the housing part, wherein the recesses are formed on the inner surfaces of the end walls facing towards the receiving opening.The recesses can each be trough-shaped.

[0019] The locking element is preferably designed such that it can be disengaged from the housing part in order to release the locking of the holding frame with the housing part. This can preferably be done with the aid of a tool, such as a screwdriver. For this purpose, the locking element can have a tool receiving area into which the tool can engage in order to move the locking element from a locked position to an unlocked position. The tool receiving area is preferably formed centrally along the length of the locking element. The tool receiving area can have a free space into which the tool can engage. The tool receiving area can be in the form of a tab formed or molded onto the locking element.

[0020] The locking element can be designed in the form of a wire body. The locking element can be formed from a round wire, in particular bent. The locking element designed as a wire body can have the shape of a bracket.

[0021] It is also possible for the locking element to be formed from a sheet metal strip. The locking element then preferably has a flat design, at least in some areas.

[0022] Furthermore, it is possible for the locking element to be formed from a displaceably mounted latching element and an actuating lever, wherein the latching element can be moved into a locked position and into an unlocked position by means of the actuating lever. To release the locking element from the latching position with the housing part, the aid of a tool is then no longer necessary, since this can be done directly via the actuating lever. The latching element is preferably mounted displaceably transversely to the direction of insertion of the holding frame into the housing part in order to be able to engage and disengage from the housing part. The actuating lever is preferably pivotably mounted in such a way that when the actuating lever is pivoted about a pivot axis, an axial or translational movement of the latching element occurs.

[0023] The at least one locking element and the at least one spring element can be formed from separate components. The locking element and the spring element can then be arranged and mounted separately from one another on the support frame, in particular on the flange section of the support frame. Preferably, two spring elements are assigned to each locking element, so that one locking element and two spring elements are arranged on each of the two flange sections of the support frame.

[0024] Alternatively, it is also possible for the at least one locking element and the at least one spring element to be formed as a single-piece component. The single-piece component then preferably forms a locking element and two spring elements, whereby this single-piece component can be arranged on the flange portion of the support frame. Such a single-piece component can, for example, be punched and bent from a sheet metal strip.

[0025] Preferably, both in the one-piece and in the separate design of the locking element and the spring elements, the locking element is arranged between two spring elements.

[0026] The object of the invention is further achieved by means of a connector part of a connector, which has an assembly designed and further developed as described above and at least one contact insert inserted into the receiving space of the holding frame. The contact inserts can be inserted into the holding frame in a modular manner, so that the contact inserts can be combined with one another in any desired manner. The contact inserts can each have one or more contacts, so that the combination of the contact inserts can create a mating face to which an associated mating connector part can be attached in a corresponding manner to provide electrical contact.

[0027] Furthermore, the object according to the invention is achieved by means of an electronic device which has at least one assembly described above, designed and further developed and / or at least one connector part designed and further developed as described above.

[0028] The invention is explained in more detail below with reference to the attached drawings using preferred embodiments.

[0030] Fig. 1 shows a housing part 110, into which a housing such as in Fig. 3 shown holding frame 111 can be used to mount an assembly 100 as shown in Fig. 7 shown to train. Fig. 2 shows that in Fig. 1 shown housing part 110 in a sectional view along the Fig. 1 shown line AA.

[0031] The housing part 110 has a receiving opening 112 into which the holding frame 111 can be inserted in an insertion direction E, so that in the inserted position, as shown for example in Fig. 7 As shown, the holding frame 111 is circumferentially enclosed by the housing part 110. The receiving opening 112 is delimited by two opposing end walls 113, 114 and two opposing longitudinal side walls 115, 116. The end walls 113, 114 are arranged at a right angle to the longitudinal side walls 115, 116.

[0032] Within the receiving opening 112, four support sections 117 are formed, on which the holding frame 111 rests in the inserted position. The four support sections 117 are formed at the four corners of the receiving opening 112, so that each support section 117 is connected to one of the end walls 113, 114 and to one of the longitudinal side walls 115, 116 of the housing part 110. The support sections 117 are formed, at least in regions, from an electrically conductive material, such as a metal, so that an electrical contact can be formed between the housing part 110 and the holding frame 111 via the support sections 117. If the holding frame 111 is at a ground potential, the housing part 110 is also connected to the ground potential, whereby a PE contact can be formed.

[0033] To form this PE contact, spring elements 118 are arranged on the holding frame 111, which are made of an electrically conductive material and rest on the support sections 117 in the inserted position of the holding frame 111 in the housing part 110. As shown in Fig. 3 As can be seen, four spring elements 118 are arranged on the holding frame 111, so that each support section 117 of the housing part 110 can be assigned a spring element 118.

[0034] The holding frame 111 has two laterally formed flange sections 119, to which the spring elements 118 are held and fastened. Two spring elements 118 are arranged on each of the two flange sections 119. In the inserted position, the holding frame 111 rests with the spring elements 118 on the support sections 117 of the housing part 110.

[0035] The spring element 118 is in Fig. 4shown individually. The spring element 118 is designed here in the form of a stamped and bent part. The spring element 118 is punched from a sheet metal strip and bent into the desired shape.

[0036] The spring element 118 has a fastening section 120 and a free end section 121 adjoining the fastening section 120. The fastening section 120, together with the free end section 121, is shaped or bent such that the spring element 118 has an S-shape.

[0037] The spring element 118 is mounted and secured to the flange portion 119 of the support frame 111 via the mounting portion 120. The mounting portion 120 is bent in a U-shape. The mounting portion 120 has a first leg 122 and a second leg 123, wherein the first leg 122 and the second leg 123 are connected to one another via an arcuate portion 124. The first leg 122 and the second leg 123 extend substantially parallel to one another. The arcuate portion 124 forms a 180° bend.

[0038] A locking tab 125 is formed on the fastening section 120, via which a locking connection can be formed between the spring element 118 and the flange section 119. The locking tab 125 is formed on the first leg 122. The locking tab 125 is sheared out of the material of the first leg 122. The locking tab 125 is sheared out in such a way that it is directed toward the second leg 123. The locking tab 125 is formed approximately in the center of the first leg 122.

[0039] The free end section 121 is connected to the fastening section 120 via a further curved section 142. The free end section 121 directly adjoins the second leg 123 of the fastening section 120. The free end section 121 forms a spring tab. The free end section 121 forms a third leg of the spring element 118. The free end section 121 is approximately the same length and width as the second leg 123 of the fastening section 120. Fig. 4shows the spring element 118 in a relaxed state, in which the free end portion 121 extends at an angle of 10° ≤ α ≤ 40° to the flange portion 119 of the holding frame 111 and also to the second leg 123. The first leg 122 and the second leg 123 of the fastening portion 120, however, extend parallel to the flange portion 119 of the holding frame 111 and thus parallel to each other both in the relaxed state and in the tensioned state of the spring element 118.

[0040] In addition to the spring elements 118, a locking element 126 is arranged on each of the two flange sections 119, by means of which a fastening and, in particular, a locking of the holding frame 111 to the housing part 110 in the inserted position can be formed. A locking element 126 is arranged between each of the two spring elements 118, as shown in Fig. 3can be seen. In order to form a locking mechanism, the two locking elements 126 are in engagement with the housing part 110 in the inserted position, as shown in Fig. 7 is shown.

[0041] For this purpose, a recess 127 is formed on each of the two end walls 113, 114 of the housing part 110, into which the locking elements 126 can engage in the inserted position. The two recesses 127 are formed on the inner surface 128 of the end walls 113, 114 facing in the direction of the receiving opening 112, as can be seen in particular in the sectional view of the Fig. 2 can be seen. The two recesses 127 are arranged opposite each other.

[0042] The locking element 126 is in the Fig. 3 to 7shown embodiment in the form of a wire body, in particular a round wire. The locking element 126 is fastened to the holding frame 111 via its two free ends 129, 130. For this purpose, openings 131 are formed on the holding frame 111, into which the free ends 129, 130 of the locking element 126 are inserted, as shown, for example, in Fig. 3 can be seen. Due to the insertion fastening of the two locking elements 126 in the openings 131, the locking elements 126 are pivotally mounted relative to the holding frame 111, in particular relative to the flange sections 119 of the holding frame 111, so that the locking elements 126 can be pivoted into the recesses 127 of the housing part 110.

[0043] The locking elements 126 have a tool receiving area 132 into which a tool can be received or hooked in order to release the respective locking element 126 from the locked position, in which the locking element 126 engages in the recess 127, and to transfer it into the unlocked position. At the tool receiving area 132, the locking element 126 is bent in a substantially U-shape. The tool receiving area 132 is formed approximately centrally along the length of the locking element 126.

[0044] At the Fig. 3 to 7 In the embodiment shown, the locking elements 126 and the spring elements 118 are each designed as separate components.

[0045] Fig. 6 shows the assembly 100 when inserting the Fig. 3shown holding frame 111 into the receiving opening 112 of the housing part 110, wherein the holding frame 111 is inserted into the housing part 110 in the insertion direction E together with the locking elements 126 and spring elements 118 fastened to the holding frame 111. The holding frame 111 is inserted into the receiving opening 112 of the housing part 110 until the two flange sections 119 of the holding frame 111 come to rest on the receiving sections 117 of the housing part 110 via the spring elements 118 arranged on the flange sections 119. Since the spring elements 118 protrude from the flange sections 119 with their free end sections 121 and are inclined in the direction of the receiving sections 117, the spring elements 118 come into contact with the support sections 117.Due to the contact of the free end sections 121 with the support sections 117, the free end sections 121 are bent in the direction of the respective flange section 119 upon further insertion of the holding frame 111 in the insertion direction E, whereby the spring elements 118 are tensioned and thus also in the inserted position, as shown in . Fig. 7 shown, the spring elements 118 can at all times form a secure contact with the support sections 117 and thus a secure contact, in particular a secure PE contact, between the housing part 110 and the holding frame 111. In the tensioned state, as shown in Fig. 7 As shown, the free end portion 121 of the spring elements 118 is aligned parallel to the respective flange portion 119.

[0046] When inserting the holding frame 111 into the receiving opening 112 of the housing part 110, the two locking elements 126 can automatically snap into the respective recess 127, so that the locking elements 126 engage in the recesses 127 in the inserted position, as shown in Fig. 7 is shown.

[0047] In the Fig. 8 to 11 another possible design of an assembly 100 is shown.

[0048] The spring elements 118 here have essentially the same design as those in the Fig. 3 to 7 shown spring elements 118, wherein in the Fig. 8 to 11In the embodiment shown, however, the spring elements 118 are formed integrally with their associated locking element 126. Here, one locking element 126, together with two spring elements 118, forms a one-piece component. Here, too, the locking element 126 is arranged between two spring elements 118. The locking element 126 is connected to the fastening sections 120 of the spring elements 118, in particular to the first leg 122 of the fastening sections 120. The spring elements 118 are pushed with their fastening sections 120 onto the flange sections 119 of the holding frame 111, so that the spring elements 118 engage around the flange sections 119 with their fastening sections 120. The fastening of the locking element 126 to the holding frame 111 is effected here via the two spring elements 118 assigned to the respective locking element 126, which are fastened to a flange section 119 of the holding frame 111.

[0049] The locking element 126, together with the two spring elements 118 connected to the locking element 126, is punched out of a sheet metal strip and bent. The locking element 126 has a locking tab 133, which in the inserted position, as shown in Fig. 11 shown, hooks or hooks into the recess 127 on the housing part 110. A tool receiving area 132 is formed on the locking tab 133, which is designed in the form of a window-like opening on the locking tab 133.

[0050] The functionality when inserting the holding frame 111 into the housing part 110 is shown in Fig. 8 to 11 shown design is equal to that in Fig. 3 to 7 shown design, so that particular attention should be paid to the explanations regarding the Figures 6 and 7 is referred to.

[0051] Fig. 12 to 14 show another possible design of an assembly 100. In the Fig. 12 to 14In the embodiment shown, the spring elements 118 are the same as those in Fig. 3 to 7 and the Fig. 8 to 11 shown spring elements 118, so that the functioning of the spring elements 118 is the same.

[0052] However, the Fig. 12 to 14 The locking elements 126 shown are each formed from a displaceably mounted locking element 134 and an actuating lever 135, wherein the locking element 134 can be transferred at least into an unlocked position via the actuating lever 135. The actuating lever 135 has a pivot axis 136, via which the actuating lever 135 is pivotally mounted on the holding frame 111. Two openings 137 are provided on the holding frame 111 for each actuating lever 135, in which openings the pivot axis 136 of the actuating lever 135 is rotatably mounted. Furthermore, the actuating lever 135 has a handle portion 138, via which a user can manually actuate the actuating lever 136.

[0053] The locking element 134 of the respective locking element 126 is mounted on the holding frame 111 so as to be displaceable transversely to the insertion direction E. Between the actuating lever 135 and the locking element 134 of a locking element 126, a spring element 139 in the form of a spiral spring is arranged, which can apply a tensioning force between the actuating lever 135 and the locking element 134. The locking element 134 has a bent locking edge 140, with which the locking element 134 hooks into the recess 127 of the housing part 110 in the inserted position, as shown in Fig. 14 can be seen. The locking edge 140 is bent here at a 90° angle to the remaining area of ​​the locking element 134.

[0054] When inserting the holding frame 111 into the housing part 110 in the insertion direction E, the spring elements 118 first come into contact with the support sections 117 and are acted upon in the same way as in the Fig. 3 to 11As soon as the flange sections 119 of the holding frame 111 rest on the support sections 117, the spring force of the spring elements 139 pushes the locking elements 134 with their locking edge 140 into the respective recess 127 on the housing part 110, where they can hook behind them to form a fastening and thus a locking connection between the holding frame 111 and the housing part 110 in the inserted position. This locking connection can be released again by a manual pivoting movement of the actuating lever 135.

[0055] For everyone here in the Fig. 1 to 14In the embodiments shown, the spring elements 118 form both an electrical contact, in particular a PE contact, between the holding frame 111 and the housing part 110 and, in the inserted position, they simultaneously exert at least a compressive force D on the locking elements 126 in order to be able to hold them securely in the respective recess 127, so that no unintentional detachment of the holding frame 111 from the housing part 110 can occur. The compressive force D applied by the tensioned spring elements 118 acts counter to the insertion direction E, whereby the locking elements 126 are pressed against an upper edge 143 of the respective recess 127 of the housing part 110.

[0056] All holding frames 111 shown here have a receiving space 141 into which preferably several contact inserts can be inserted. List of reference symbols
