DETAILED DESCRIPTION
[0055] In the Figs. partially the same reference numerals are used for components or features of different embodiments or a plurality of components or features in the same embodiments which have the same or a similar geometric design and/or function. In this case in one embodiment different components or features are distinguished by an additional letter a, b, . . . . Here, reference can also be made to all of these components or reference numerals by not using of the additional letter.
[0056]
[0057] An accommodation 5 is formed in the component 3 or base body 4. For the embodiment according to
[0058] The accommodations 5 comprise insertion openings 8a, 8b, 8c. It is possible to insert the plug 7 through the insertion openings 8a, 8b, 8c into the accommodations 5. The accommodations 5 might be through-accommodations of the component 3 or the base body 4 or might have a bottom which provides a limitation for the depth of the insertion of the plug 7 into the accommodation 5.
[0059] Furthermore, the crimping tool locator 1 comprises a lightening device 9. The lightening device 9 comprises an energy source 10, a lamp 11 and a switch 12. A material region 13 made of a transparent material of the component 3 or the base body 4 is arranged between the lamp 11 and at least one associated accommodation 5b. A cone of light 14 of the lamp 11 is able to illuminate the interior of the accommodation 5b (here the workpiece 6 or the plug 7) through the material region 13. In
[0060] Optionally it is also possible that the accommodations 5 are not delimited or defined only by the transparent material 5 of the base body 4. Instead, the accommodations 5 are equipped with linings 41 of a harder and/or more wear resistant and in particular non-transparent material (e.g. a plastic material or metal). Here, the linings 41 form inner surfaces 45 by which the plug 7 is held and/or guided in the accommodations 5. Together with the transparent material of the base body 4 in a partial region 44 the inner surfaces 45 of the linings 41 delimit or define the accommodations 5. Here, the inner surfaces 45 and the transparent material of the base body 4 form a flush common inner surface for defining or delimiting the accommodation 5 or together form a contour which is suitable for accommodating and guiding the plug 7. The linings 41 are embedded into the transparent material of the base body 4. For an embodiment not shown here it is possible that the linings 41 made of the transparent material of the base body 4 protrude in the way of ribs or protrusions or contact bodies. In this case it might then also be possible that the plug 7 arranged in an accommodation 5 contacts the lining 41 whereas the plug 7 does not contact an adjacent partial region 44 of the transparent material. The circumference or the contour of the accommodations 5 is delimited by partial circumferential region 72a, 73a, 72b, 73b. Here, the limitation in the partial circumferential regions 72a, 72b is provided by the transparent material of the base body 4 whereas the limitation in the partial circumferential regions 73a, 73b is provided by the inner surfaces 45 of the linings 41.
[0061]
[0062] In the crimping pliers 21 the hand levers 22, 23 are actuated manually with a relative movement of the hand levers 22, 23 towards each other. By a drive mechanism the movement of the hand levers 22, 23 is coupled to a relative movement of the die halves 24, 25 between which a crimping region is formed wherein a workpiece (here a plug 7 with a cable arranged therein) is crimped. With the pivoting movement of the hand levers 22, 23 towards each other it is possible to induce a relative crimping stroke of the die halves 24, 25 along a longitudinal axis 26.
[0063] The crimping pliers 21 define a pliers head plane 27 which has an orientation parallel to the x-y-plane in
[0064]
[0065] The covering plate 34 and the base body 4 are screwed to each other by screws 36a, 36b. Here, the screws 36a, 36b can be screwed with the material of the base body 4, in particular with the plastic material. However, it is also possible that threaded sleeves are cast with or bonded to the material of the base body 4. In this case the screws 36a, 36b are screwed into the threaded sleeves.
[0066] On the side facing away from the tool head 28 the base body 4 forms a recess (which is not shown in
[0067] In particular in
[0068] The base body 4, the covering plate 33 and/or the covering plate 43 is/are preferably made of a transparent plastic material. Instead, the linings 41 are made of a metallic material as steel or aluminium or a non-transparent plastic material. Preferably, the linings 41 have a higher hardness or wear resistance than a transparent or non-transparent plastic material used for the base body.
[0069] In a generally known fashion the crimping tool locator 1 can be secured in single pivoting positions (in particular in the insertion position and/or the operating position) by a permanent magnet 46 which cooperates with a counter magnet of the tool head 28 in the operating position and/or by a latching device 47.
[0070] Due to the fact that at least one of the components 3 is made of a transparent plastic material, the user of the crimping tool 20 is able to inspect the interior of the accommodations 5. Assistance is provided to the user by the illuminating device 9 which illuminates the plug 7 arranged in the accommodation 5 through the transparent material.
[0071]
[0072]
[0073] According to
[0074] For the recesses 5a to 5c a lining 41a to 41c is used as shown in
[0075]
[0076] Also here the crimping tool locator 1 comprises a latching device 47. The latching device 47 comprises an actuation button 59, a latching spring 60 and a latching body 61. It is also possible (as can be seen for the recesses 71f to 71j in
[0077]
[0078] Preferably the illuminating device 9 is equipped with an energy source 10, in particular a battery or a button cell battery which does not require an exchange over the lifetime of the crimping tool locator 1 which is in particular more than 10 years. It is possible that a pre-fabricated illuminating circuit is inserted into the inner chamber 48 of the crimping tool locator 1. Here, it is also possible that a circuit of this type is cast to a block, in particular made of plastic, and the circuit is inserted as a block of this type into the inner chamber 48. It is possible that the block already comprises an outer geometry which is adapted to the geometry of the inner chamber 48 so that when inserting the block into the inner chamber 48 automatically the correct position and orientation of the block and so also of the lamp 11 is defined.
[0079] It is possible that the latching device 47 is also used for sliding relative to the pliers head 28 along an actuating slope during the relative movement of the crimping tool locator. In this way simultaneously to the movement of the crimping tool locator 1 a movement parallel to the pivoting axis 29 can be induced.
[0080] The covering plates 33, 34 and the base body 4 can be made of any materials with any properties. Preferably, at least one component of the covering plates 33, 34 and the base body 4 is made of a transparent plastic material. The linings 41 are manufactured from a harder or more wear resistant material than the transparent plastic material. This might also be a (transparent or non-transparent) plastic material or also e.g. a metallic material. For the type of provision of the linings 41 at the crimping tool locator 1 there are a lot of options. For a first variant the linings 41 are inserts 64. Accordingly, the linings 41 are manufactured and provided separately. The linings 41 are inserted into the recess 71 of the base body 4. The linings 41 enter into the recesses 40 or grooves 42. In a state inserted in this way into the recess 40 or groove 42 the linings 41 can be connected to the recesses 40 by a press fit, friction lock, by latching, by locking, by gluing or adhesively bonding or by an additional fixing means and secured here.
[0081] For another variant the linings 41 are provided in the crimping tool locator 1 by means of a method for manufacturing which is very schematically shown in
[0082] Subsequently, in a second method step 66 the intermediate product produced from the first material is inserted into a different mould or inserts or cores are removed from the mould and replaced by different inserts or cores. The different mould or the different inserts or cores have a form or geometry which corresponds to the cross section of the in the end produced accommodations 5 including the linings 41. Accordingly, the form or the inserts or cores do not have the ribs for forming the grooves 42. In the simplest case the inserts or cores used in the second method step 66 generally correspond to the inserts or cores which have been used in the first method step 65 with the exception that the inserts or cores used in the second method step 66 do not have ribs. Instead, the inserts or cores have an outer surface which is flush in the adjacent partial region 44 of the recess 71 or which transits in a way corresponding to the contour of the workpiece 6 to the adjacent partial region 44 of the recess 71. Between the intermediate product manufactured from the first material and the form of the mould, the outer surface of the insert or core a cavity remains. The geometry of the cavity corresponds to the geometry of the lining 41 which is to be produced. A second material, in particular a non-transparent plastic material or a metallic material, is then inserted into this cavity. After the hardening the second material forms the lining 41.
[0083] Optionally it is possible that in a subsequent method step 67 there is a post processing of the accommodations, in particular a milling or boring post processing.
[0084] For the embodiment of the linings 41 according to
[0085] Also for the bracket-like or strut-like design of the linings according to
[0086] Generally, an inventive crimping tool locator might also be used (differing from the shown embodiment) for any crimping tool or crimping pliers and for any other design of the crimping tool locator. For this purpose in the following only some examples will be mentioned. However, options of the use of the inventive design should not be limited to these examples: [0087] Possible is a use of an inventive crimping tool locator for crimping tools as being distributed by the applicant under the labels CS10, CSV10, CSV10-LBL, CS11, CS30 or in connection with electrical crimping tools CS150 or as embodied as table crimping devices CS200, pneumatical processing systems CP600 or pneumatical crimping machines UP60. Also crimping tool locators used here can be adapted in the inventive way. [0088] It is also possible to use the invention for crimping pliers or crimping tool locators as described in the publication DE 198 32 884 C1 (corresponding to U.S. Pat. No. 6,155,095 A). Here, it is possible to pivot the crimping tool locator about a pivoting axis running through the tool head plane 27 and having an orientation transverse to the longitudinal axis and to the crimping stroke. [0089] An alternative embodiment of crimping pliers as well as of a pivotable locator which can be pivoted about a transverse axis and for which also the inventive measures might apply, is known from DE 10 2008 017 366 A1 (corresponding to U.S. Pat. No. 8,161,789 B2). [0090] Another embodiment of crimping pliers as well as of a crimping tool locator is known from DE 20 2008 003 703 U1. Here, the crimping tool locator might additionally comprise a securing element held with a pivoting degree of freedom at the base body 4. By the securing element it is possible on the one hand to additionally secure a workpiece as a plug in the accommodation and on the other hand to form a stop which defines how deep a cable can be slid into the accommodation and/or the plug. A securing element of this type might also be embodied as a cable stop element or so called wire stop. [0091] It is also possible to transfer the invention to a crimping tool locator according to DE 10 2010 061 148 A1. The crimping tool locator can be adjusted such that it is possible to arrange an accommodation of the crimping tool locator alternatively behind different dies of the crimping pliers. Here, the publication discloses a crimping tool locator wherein the accommodations can be displaced transverse to the crimping direction in the pliers head plane or wherein the crimping tool locator can be rotated similar to a revolver about an axis having an orientation perpendicular to the tool head plane 27. [0092] Another embodiment of crimping pliers comprising a crimping tool locator upon which the inventive measures can be applied is disclosed in publication EP 2 672 580 A1.
[0093] Within the frame of the invention a high hardness is in particular interpreted as a higher hardness corresponding to at least one of the common measuring methods for determining the hardness. This might e.g. be a hardness of [0094] a universal hardness according to DIN EN ISO 14577, [0095] a Rockwell hardness (HR) according to DIN EN ISO 6508-1, cp. also Lexikon Kunststoffprfung and Diagnostik (W. Grellmann, C. Biergel, K. Reincke) or http://wiki. polymerservice-merseburg.de/index.php/Rockwell-Hrte (date of inspection 21.10.2016), [0096] a hardness Brinell according to DIN EN ISO 6506-1 to EN ISO 6506-4, [0097] a hardness according to the hardness analysis with a Poldi hammer, [0098] a hardness Vickers (HV) according to DIN EN ISO 6507-1: 2005-4 2005, [0099] a hardness according to Knoop according to DIN EN ISO 4545-1-4, [0100] a Shore-hardness according to the standard DIN EN ISO 868 and DIN ISO 7619-1, in particular a hardness Shore A, Shore B, Shore C or Shore D, cp. also http://wiki. polymerservice-merseburg.de/index.php/Shore-Hrte (date of inspection 21.10.2016), [0101] a hardness Barcol according to standard DIN EN 59.
[0102] Preferably a hardness of the lining 41 according to the aforementioned definitions is at least 20%, 50% or even 100% higher than the hardness of the component 3 made of the transparent or non-transparent plastic material. The lining 41 might here consist of metal or a plastic material. For one example the lining 41 is manufactured from polyamide. Preferably, the lining 41 comprises a hardness Shore A being higher than 100 N/mm.sup.2, higher than 120 N/mm.sup.2, higher than 140 N/mm.sup.2, higher than 150 N/mm.sup.2 or even higher than 170 N/mm.sup.2. It is also possible that the lining 41 has a ball indentation hardness being higher than 100 N/mm.sup.2, higher than 120 N/mm.sup.2, higher than 140 N/mm.sup.2, higher than 150 N/mm.sup.2 or even higher than 170 N/mm.sup.2. In order to mention only some non-limiting examples for further possible materials for the lining 41, it is mentioned that here a PVC-C plastic material, a PMMA-XT plastic material, a PMMA-GS plastic material, a PC plastic material, a SAN plastic material, a PA 6 plastic material, a PA 6.6 plastic material, a POM plastic material, a PET plastic material, a PVDF plastic material, a PEEK plastic material, a PES plastic material, a PSU plastic material, a PEI plastic material, in particular with a hardness of at least 100 N/mm.sup.2 (Shore A or ball indentation hardness) can be used.
[0103] A wear resistance can be determined on the basis of the standard DIN 50320. Within the frame of the invention it is possible that the lining 41 comprises a hardened and/or coated surface for increasing the wear resistance. It is also possible that the increased wear resistance is provided by a higher stiffness or tensile strength or a higher module of elasticity of the material.
[0104] A transparent material of the base body 4 and/or of a covering plate 33, 34 (preferably the material by which the accommodation 5 is delimited in the partial region 44) is e.g. a material on the basis of a polycarbonate (also abbreviated as PC) as these are in particular distributed under the registered trademarks Makrolan or the registered trademark Lexan or as specified on the internet-site http://www.kern.de/cgi-bin/riweta.cgi?nr=2301&Ing=1 (date of inspection 21.10. 2016) with the material number 2301, an acryl glass material or an acryl material, a Plexiglas material (registered trademark), a PMMA material or a SAN material (styrol-acrylnitril).
[0105] It is also possible that the base body 4 is manufactured from a non-transparent material whereas the lining 41 (in particular a web of a lining 41) is manufactured from a transparent material. The transparent material region of the lining 41 can then be used for transferring light from the lightening device similar to a light channel or optical wave guide to the position of interest, in particular in the accommodation 5 and/or to the crimping region. For this purpose preferably the light is introduced in an end region of the transparent material region, transferred through the transparent material region and the light exits then in the other end region which is preferably facing towards the accommodation 5 or the crimping region from the transparent material region. For this proposal it is also possible that the material of the lining 41 has a smaller hardness than the material of the base body 4 in the partial region 44.
[0106] Within the frame of the invention under the feature lining in particular a material region is subsumed which is embedded into the component 3 or the base body 4 which can be the case by material bonding or by an insert 64. In this embedded state the lining 41 is surrounded by the material of the component 3 or the base body with the exception of the inner surface 45 by which the lining 41 limits the accommodation, by which the lining 41 cooperates with the workpiece or plug and/or by which the lining 41 protrudes into the accommodation 5.
[0107] Many variations and modifications may be made to the preferred embodiments of the invention without departing substantially from the spirit and principles of the invention. All such modifications and variations are intended to be included herein within the scope of the present invention, as defined by the following claims.
