Description

[0001] The present invention relates to an insert for a test contactor for testing an electrically conductive test element, a test contactor for testing an electrically conductive test element, and a use of an insert for a test contactor for testing an electrically conductive test element.

[0002] Conventional test contactor systems essentially consist of a test contactor and a circuit board and are used to test chips, such as computing chips that can be used as CPU cores. A chip is inserted into the open test contactor, and then the test contactor is closed. The test contactor is mounted on a circuit board, so that when the test contactor is closed, its cover exerts pressure on the chip, ensuring reliable contact between the chip and the test contactor's spring-loaded contact pins. The chip then transmits this pressure through the spring-loaded contact pins to the circuit board, ensuring reliable contact between the pins and the board.

[0003] When the test contactor closes, a specific and potentially localized pressure is applied to the chip under test, depending on how the chip is inserted and, in particular, on its geometry. Therefore, various test contactors feature movable centering elements that move towards the chip under test when the test contactor enters its test state.

[0004] However, the supposedly automatic centering of the chip under test can, depending on the contour of the chip under test, lead to displacements or gaps between the contact points of the chip under test and one or more spring contact pins.

[0005] US 7,123,034 B2 describes a contact device used for the automated testing of integrated circuits. The device or assembly enables the rapid automated test transition from testing a multitude of devices of a first body shape to a multitude of devices of a second body shape, both device types having electrical contacts arranged within a device contact plane and according to a common grid pattern. The common grid pattern can be arranged along an X-axis and an orthogonal Y-axis, with the contact points along each axis spaced equally, for example, one contact point at each 0.8 mm by 0.8 mm location, or with the contact points spaced differently in each dimension, for example, a multitude of contact points 0.8 mm in length along the X-axis and 1.2 mm in length along the Y-axis.The contact device can have multiple openings, which are useful for testing several devices simultaneously.

[0006] DE 11 2005 002 859 T5 describes two holding sections for electronic devices, which are formed on an insert intended for mounting on a test tray of a handling device for electronic devices. The two holding sections for electronic devices are arranged in positions that enclose a standard hole, which is used as a positional standard during alignment. Using an insert with a plurality of holding sections for electronic components increases the number of IC components that can be held per unit area on the test tray and improves throughput.Even if the two retention sections for electronic devices are arranged in positions that include the standard hole, both retention sections for electronic devices can be close to the standard hole, so that positional deviation of the IC components caused by thermal expansion or thermal contraction of the insert can be suppressed and the occurrence of contact defects due to positional deviations is suppressed.

[0007] It is therefore an object of the present invention to provide an insert for an improved test contactor which in particular enables improved positioning of test elements in the test contactor.

[0008] Furthermore, it is an object of the present invention to provide an improved test contactor, which in particular enables improved positioning of test elements in the test contactor, and to provide a use of an improved test contactor, in particular for improved positioning of test elements in the test contactor.

[0009] The aforementioned problems are solved by the subject matter of the independent claims; preferred embodiments are the subject matter of the dependent claims.

[0010] One aspect of the invention relates to an insert for a test contactor for testing an electrically conductive test element, - wherein the device comprises several contact elements designed to electrically contact the electrically conductive test element in the test state of the test contactor, - wherein the insert comprises a plurality of openings or coding openings, wherein the openings or coding openings are arranged on an upper side of the insert facing the test element in the test state, - wherein in the test state at least one pin is arranged in at least one opening of the plurality of openings, such that the insert has a coding for a test element corresponding to the coding.

[0011] The coding effect of the pin or multiple pins in the openings of the multiple openings during testing allows the insert to advantageously improve a test contactor, and in particular, the positioning of test elements within the test contactor. Specifically, it can prevent incorrect positioning of test elements within the test contactor, and / or prevent the placement of an incorrect test element within the test contactor. Furthermore, it can advantageously reduce the probability of a test element slipping out of place on the test contactor.

[0012] Preferably, in the test state, exactly one pin is arranged in exactly one opening of the plurality of openings. However, several pins can also be arranged, each in one opening.

[0013] The coding which the insert exhibits or forms may, in particular, be such that it essentially corresponds to a coding of a test element to be tested, especially one or more coding recesses of the test element to be tested.

[0014] The coding that the insert exhibits or forms therefore advantageously prevents the placement of a test element not intended for testing by the test contactor. Preventing the placement of an unintended test element can be due, for example, to an insert geometry unsuitable for the test element and facing it in the test state, contact elements unsuitable for the test element, or another unsuitable configuration of the test contactor, which may be related to the insert itself or to parts of the test contactor other than the insert.

[0015] The openings or coding openings of the insert can each be specifically designed to receive exactly one pin. The pin can be releasably held in place, allowing it to be removed from the opening without damage. For example, the pin can be held by friction. Alternatively, the pin can be permanently attached, meaning it cannot be removed from the opening without damage. For example, the pin can be held by a material bond, such as by being glued into the opening.

[0016] In exemplary embodiments, the coding which the insert has or forms can, in particular, be designed to prevent a test element from being arranged incorrectly on the insert.

[0017] For example, the coding that the insert has or forms can be specifically designed to form a Poka-Yoke configuration. In other words, the coding that the insert has or forms through the pin or pins arranged in one or more of the openings can be such that the placement of a test element not intended for testing by the test contactor on the insert is prevented, and / or that the misaligned placement of a test element intended for testing by the test contactor on the insert is prevented.

[0018] In addition to an incompletely accurate positioning of the test element, for example by rotating it at a certain angle on the insert, a misaligned arrangement of the test element on the insert can include, in particular, an arrangement of the test element on the insert rotated by approximately 180° in the plane, i.e., the front and back of the test element are reversed, and / or an arrangement of the test element on the insert upside down, i.e., the top and bottom of the test element are reversed.

[0019] The pin or pins which the insert may have in order to display or form a coding may in particular have a predetermined length which is designed to prevent the test contactor from closing when the coding of the insert does not engage with a test element corresponding to the coding, i.e. in particular when the coding of the insert does not engage with corresponding coding recesses of the test element.

[0020] The pin or pins may, for example, have a predetermined length which, together with the thickness of the test element, is designed to prevent the test contactor from entering a closed state in which, in particular, complementary clamping means of the test contactor are engaged in order to define a predetermined pressure on the test element in the test state.

[0021] For example, a pin can have a length of approximately 3 mm to 20 mm, preferably approximately 5 mm to 10 mm, and particularly preferably approximately 10 mm. For example, a pin can have a diameter at its thickest point of approximately 1 mm to 5 mm, preferably approximately 2 mm to 3 mm, and particularly preferably approximately 2 mm. The holes can be designed to be complementary to the dimensions of the pin.

[0022] According to a preferred embodiment, all holes have the same diameter. It is also possible for the holes and / or pins to have different diameters. Thus, coding can also be achieved based on the different diameters of the holes and pins. For example, one coding is defined using pins and holes of a first diameter. A second coding is defined using pins and holes of a second diameter, where this second diameter is larger than the first, meaning the second pins only fit into the second set of holes.

[0023] The pin(s) can be tapered towards one end or both ends, in particular conical in shape.

[0024] If an operator attempts to close a test contactor on which an incorrect test element or a test element that is incorrectly oriented is attached to the insert, this can advantageously prevent incorrect, i.e., unintended, contacting of the contact elements. Similarly, the coding that the insert has or forms can advantageously improve the service life of the contact elements, and consequently, the service life of the insert and, subsequently, of the test contactor.

[0025] For example, the contact elements can be arranged at least partially on or within the insert. In particular, the contact elements can extend continuously through the insert, especially in such a way that they can be electrically contacted from an upper side and / or a lower side of the insert. The upper side and the lower side refer in particular to an up-down orientation of the insert, which the insert assumes in a typical use, for example on a flat worktop, and in particular as a substantially vertical direction.

[0026] The openings of the majority of openings can each extend, in particular, essentially in an upward-downward direction, in order to arrange the pin(s) facing upwards, especially towards the test element, and furthermore, especially towards the pressure section of the test contactor when the test contactor is closed, and in particular in a way that is clearly visible to an operator.

[0027] The multiple contact elements can, but are not limited to, be arranged on the insert, in particular with an extension substantially parallel to the top-bottom direction. The multiple contact elements can, in particular, be arranged at least partially within the insert.

[0028] The multiple contact elements can be arranged on or in the insert in such a way that the multiple contact elements are configured to electrically connect a test element arranged above the insert to a printed circuit board, in particular to a printed circuit board arranged below the insert, in the test state.

[0029] The multiple contact elements can be arranged on the insert in such a way that the multiple contact elements are configured to electrically connect a test element adjacent to the insert at least partially from above with a printed circuit board, in particular with a printed circuit board adjacent to the insert at least partially from below, in the test state.

[0030] In further exemplary embodiments, the contact elements of the multiple contact elements can protrude from the insert on one or both sides, in particular protrude from the insert on one or both sides essentially parallel to the top-bottom direction.

[0031] The contact elements of the multiple contact elements can in particular be spring contact elements, for example elastically restorable spring contact elements.

[0032] The aforementioned design of the contact elements and their arrangement on the insert advantageously ensures a safe, electrically conductive contact of a test element in the test state.

[0033] In the following sections, various terms will be used repeatedly, the understanding of which should be facilitated by the definitions below.

[0034] Electrically conductive test element: The electrically conductive test element, as used here, is a test element that is tested by making electrical contact with it, for example, by connecting it to one or more printed circuit boards. The test element could, for example, be a computing chip that can be used as a CPU core or similar. When only the term "test element" is used here, it also refers to the electrically conductive test element.

[0035] A printed circuit board, as described herein in particular as a circuit board suitable for electrically conductive contacting of the test element, has, in particular, fixing and / or positioning means for attachment to the test contactor, for example, for attachment to the insertion section of the test contactor, and especially for attachment to the insert of the insertion section of the test contactor. The fixing and / or positioning means may, for example, include receiving holes or elements engaging in receiving holes for attachment to the test contactor, in particular for attachment to the insertion section or the insert. The printed circuit board may, in particular, be a PCB (printed circuit board).

[0036] A pin or several pins, which can be arranged in the openings or coding opening of the insert to form a code for a test element corresponding to the code, can in particular be elongated elements which have at least a partially round or circular, elliptical, and / or polygonal cross-section. The pin or several pins can each in particular have a longitudinal extent which is at least approximately four times, in particular at least approximately ten times, for example at least approximately fifteen times, the extent of the cross-section of the pin or the diameter of the respective pin. The pin or several pins can accordingly be elements that extend substantially axially.

[0037] In exemplary embodiments, one or more pins, each designed for placement in openings or coding holes, can have a substantially constant cross-section or diameter. This makes it advantageously simple and time-efficient to arrange the pin(s) in the holes, as the operator can position them with either their first or second end in the opening.

[0038] In other exemplary embodiments, one or more pins, each designed for arrangement in openings or coding openings, can have a sectionally essentially constant cross-section or diameter. For example, one or more pins can each have a first sectionally, facing the opening or coding opening, in particular an essentially constant cross-section or diameter, and a second sectionally, facing the coding recess of the test element, in particular an essentially constant cross-section or diameter. This advantageously increases the number of different codings that can be formed by the pins with the openings.

[0039] To form the code, the insert can have one or more pins. In exemplary embodiments, and particularly for an uncoded state of the insert, no pin may be arranged on the insert, and especially not in an opening or coding opening of the insert.

[0040] If a direction or angle is given with the addition of "essentially" or "approximately" or "about", this addition is generally intended to refer to a deviation from the direction or angle in question in the range of 0° to 5°.

[0041] If a spatial measure, spatial ratio or other ratio is given with the addition of "essentially" or "approximately" or "about", this addition is intended to indicate, in particular, a deviation from the measure or ratio in question in the range of 0% to 10%.

[0042] The "top-bottom direction," as used here, describes the direction in which the insert, the base section, and, if applicable, the fastening element are related to each other, and in particular to the test contactor. If the insert or test contactor is positioned in its usual operating position on a substantially flat work surface, the top-bottom direction is essentially vertical. It is understood that if the insert or test contactor is placed at an angle on the work surface, the top-bottom direction will deviate accordingly from the vertical direction. Where a vertical direction is subsequently mentioned, as with reference to the figures, this can also correspond to the top-bottom direction.

[0043] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, the plurality of openings on the insert can be designed such that, in the test state, by arranging one or more pins in the openings, the insert optionally has a symmetrical or asymmetrical coding.

[0044] In other words, the openings of the majority of openings can be designed on the insert in such a way that pins, in particular by reversible arrangement of the pins on one or more of the openings, can be selectively arranged on the openings to form a symmetrical or asymmetrical coding.

[0045] The openings or coding openings of the majority of openings or coding openings can be arranged or designed at least partially symmetrically to each other on the insert, particularly in a top view of the insert from above.

[0046] A user of the insert can thus advantageously create a symmetrical or asymmetrical coding by reversibly arranging one or more pins at the majority of openings or coding openings.

[0047] A symmetrical coding advantageously allows a test element to be arranged in a front-back and / or top-bottom orientation, and can be used in particular with appropriately symmetrical test elements that can be tested in their rotated arrangement to simplify the arrangement of test elements.

[0048] The front-to-back rotation of a test element refers in particular to an arrangement of the test element rotated by approximately 180° about a line parallel to the top-to-bottom direction, i.e., an arrangement of the test element rotated by approximately 180° in the plane. The top-to-bottom rotation of a test element refers in particular to an arrangement of the test element rotated by approximately 180° about a line parallel to the longitudinal direction, i.e., an arrangement of the test element rotated by approximately 180° upside down.

[0049] An asymmetric coding advantageously prevents a test element from being arranged in a front-back and / or top-bottom orientation, and / or, in particular, prevents the test contactor from closing or being moved into the closed state, and especially into the test state, when the test element is arranged or oriented in a front-back and / or top-bottom orientation. The asymmetric coding can thus advantageously prevent a twisted arrangement or orientation, and in particular incorrect arrangement or orientation, even with symmetrically designed test elements. Accordingly, an asymmetric coding improves the repeatability of tests and, in particular, protects the contact elements and / or a printed circuit board that is to be electrically connected to the test element during testing from an unintended and potentially damaging test.

[0050] The symmetry or asymmetry of the coding can refer to a mirror symmetry or a mirror plane, which extends essentially in the width direction and in the top-bottom direction of the insert, and which extends in particular through a geometric center of the insert, so that the insert is divided or is divided into opposing sections in the longitudinal direction.

[0051] Furthermore, the symmetry or asymmetry of the encoding can refer to point symmetry or to a point of reflection located essentially at the geometric center of the insert. The point symmetry can therefore refer, in particular, to a top view of the insert, with the point of symmetry located on a central axis through the insert, which extends, in particular, essentially parallel to the top-bottom direction through the geometric center of the insert. The point of symmetry can, in particular, be located in a plane in which the openings or encoding openings on the insert are arranged. In other words, the symmetry or asymmetry of the encoding can refer to point symmetry with a point of symmetry located, in a top view of the insert, at its geometric center, specifically on a central axis of the insert extending essentially in a top-bottom direction.

[0052] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, the openings can be arranged at least partially opposite each other with respect to a center of the insert.

[0053] The center of the insertion can, in particular, correspond to a geometric center of the insertion, especially essentially to a centroid of the insertion in a top view of the insertion, or essentially to the position of a centroid of the insertion, especially in a top view of the insertion.

[0054] The insert can, in particular, have a substantially plate-like or trough-like shape, extending longitudinally and in a lateral direction substantially perpendicular to these directions, and extending vertically upwards and downwards, essentially perpendicular to both the longitudinal and lateral directions. The longitudinal extent of the insert can, in particular, be greater than its lateral extent. The respective longitudinal and lateral extents of the insert can, in particular, be greater than its vertical extent.

[0055] The contact elements of the insert can be arranged, in particular, essentially along the top-bottom direction on the insert, i.e., essentially parallel to the top-bottom direction on the insert.

[0056] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, the majority of openings can be odd.

[0057] This advantageously allows for simple manufacturing of the insert, as well as a simple arrangement of pins at the openings or coding openings to form an asymmetrical pattern.

[0058] In exemplary embodiments, the openings or coding openings of the majority of openings can be arranged on essentially opposite sides of the insert in the longitudinal direction.

[0059] The openings or coding openings of the plurality of openings or coding openings can comprise an even number of openings or coding openings on a first side of substantially opposite longitudinal sides of the insert, for example, 2, 4, 6 or more openings, and an odd number of openings or coding openings on a side substantially opposite longitudinal sides of the first side, for example, 1, 3, 5, 7 or more openings. The even number of openings on the first side and the odd number of openings on the side substantially opposite the first side can each comprise one or more openings that are arranged opposite each other with respect to a center of the insert, i.e., in particular, that they are arranged point-symmetrically opposite each other on the insert when viewed from above.

[0060] This allows an operator to create either a symmetrical or asymmetrical coding in a conveniently simple manner, and in particular by reversibly arranging pins at the openings or coding openings.

[0061] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, at least two openings can have different cross-sections or diameters.

[0062] By having two or more of the openings have different cross-sections or diameters, the formation of an asymmetric coding can be advantageously simplified, and in particular the number of coding patterns that can be formed asymmetrically through the openings can be increased in a simple way.

[0063] In exemplary embodiments, the insert can comprise two or four openings on a first side of substantially opposite sides of the insert in the longitudinal direction, wherein at least one of the two or one of the four openings has a diameter or cross-section that differs from the diameter or cross-section of the other openings or the other three openings, respectively. In particular, each of the openings on the first side of substantially opposite sides of the insert in the longitudinal direction can have a different diameter or cross-section.

[0064] Furthermore, the insert can comprise one, three, or five openings on a side substantially opposite the first side in the longitudinal direction. The openings on the side substantially opposite the first side can have a diameter or cross-section that differs from the other openings arranged on the side substantially opposite the first side.

[0065] Optionally, the openings on the side substantially opposite the first side may have a diameter or cross-section that corresponds at least partially to the openings arranged on the first side.

[0066] This further advantageously simplifies the formation of an asymmetric coding, and in particular simplifies the formation of an optionally asymmetric or symmetric coding, whereby a large number of different codings can be formed using a small number of pins of different diameters.

[0067] The sides of the insert described herein as being arranged opposite each other, in particular as being arranged opposite each other in the longitudinal direction, each refer in particular to two sections or coding sections of the insert arranged opposite each other, in particular to two sections or coding sections arranged essentially opposite each other in the longitudinal direction, wherein the two sections or coding sections are each arranged in the top-bottom direction, in particular on a top or on an upper side of the insert.

[0068] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, the insert can be multi-part, such that the insert has an upper insert element facing the test element in the test state, which is attached to a lower base section with one translational degree of freedom, wherein the base section is configured to delimit the insert element at least partially laterally and from below, and The base section may have a coding section that extends laterally further than the insert element and that has at least some of the majority of openings.

[0069] This allows the insertion to be advantageously configured in a test element-specific manner, whereby the insert element, which is attached with one degree of freedom, takes into account the geometry of the test element, and / or controls the force transmission to the contact elements, and furthermore supports and / or protects the contact elements.

[0070] In particular, the arrangement of the insert element with one degree of freedom, especially with one degree of freedom in the top-bottom direction, advantageously makes it possible to reduce an initial force on the contact elements of the insert, and thereby advantageously to protect and / or support the contact elements.

[0071] If the base section, which has the openings or coding openings, extends laterally, for example longitudinally, further than the insert element, the coding for the test element can advantageously be created independently of the insert element. This simplifies the manufacturability of the insert and improves the targeted provision of the individual functions of the insert. In other words, the functionally separate provision of the coding advantageously enables efficient configuration of the insert for a test element specific to the insert.

[0072] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, the base section may have two opposing coding sections.

[0073] The two opposing coding sections can be located primarily opposite each other in the longitudinal direction of the deployment.

[0074] This allows the provision of the individual functions of the insert to be further advantageously improved independently of one another, whereby the operator can attach a test element-specific insert element to the base section in the center of the longitudinal direction of the insert, in particular reversibly, and independently set a coding of the insert, in particular by reversibly arranging one or more pins in the openings or coding openings of the insert.

[0075] In preferred embodiments of the insert for a test contactor for testing an electrically conductive test element, the insert may include a preloading means configured to preload the insert element relative to the base section.

[0076] The prestressing device can be configured, in particular, to prestress the insert element away from the base section. Furthermore, the prestressing device can be configured, in particular, to prestress the insert element essentially in a top-bottom direction relative to the base section, especially to prestress it facing the test element in the test state.

[0077] The preloading device can, for example, comprise a spring, in particular a coil spring, and / or an elastomer.

[0078] The preloading device advantageously allows for the adjustment of initial contact when a pressure section of the test contactor pushes the test element towards the contact elements. For example, the preloading device can be configured to preload the insert element away from the base section, facing the test element in the test state, and in particular to preload it along the translational degree of freedom of the insert element. The preload of the insert element by the preloading device can be such that, when the test contactor transitions into the test state, the test element first comes into contact with the insert element, thus advantageously reducing and, in particular, preventing a high initial force on the contact elements. The preloading device therefore advantageously protects and supports the contact elements through the insert.

[0079] Another aspect of the invention relates to a test contactor for testing an electrically conductive test element, wherein the test contactor comprises: - an operation as described herein, -- wherein the deployment includes a test area to which the electrically conductive test element can be arranged, -- wherein, in the test state, at least one pin is arranged in the plurality of openings; and - a pressure section which is pivotably mounted relative to the application and which is designed to push the electrically conductive test element towards at least one pin in the test state of the test contactor.

[0080] The pressure section can further be designed in particular to press the electrically conductive test element in the test state of the test contactor against the several contact elements which are arranged on the insert, and to further press the contact elements in particular against a circuit board which may be arranged, for example, below the insert on the test contactor.

[0081] Furthermore, the pressure section is specifically designed to press the electrically conductive test element against the multiple contact elements only when the pin(s) arranged at the openings or coding openings of the insert engage with complementary coding openings of the test element when the test contactor is closed.

[0082] If the coding provided by the pin(s) on the insert does not match the coding openings of the test element, the insert is specifically designed to prevent electrically conductive contact between the test element and the contact elements. This advantageously prevents unwanted and potentially damaging contact between the contact elements and / or the circuit board.

[0083] The insert can be arranged reversibly on a frame section of the test contactor, in particular the frame section and the insert can form part of a multi-part insertion section of the test contactor.

[0084] The pressure section of the test contactor can be pivotably mounted on the frame section in particular, in order to be pivotable relative to the application and the test element arranged on it, for example.

[0085] The use, its exemplary, preferred and alternative embodiments, and their effects, relate equally to the test contactor, and vice versa.

[0086] Another aspect of the invention relates to a use of an insert as described herein, wherein the use comprises the steps: - Deployment of the deployment, - Arranging one or more pins in at least one opening or coding opening of the plurality of openings to form a coding facing the test element in the test state.

[0087] In exemplary embodiments, the use of the insert can include a step of removing one or more pins from the plurality of openings or coding openings prior to arranging one or more pins in at least one opening or coding opening. This allows the insert to be advantageously, and in particular reversibly, converted from a configuration with a first coding to a configuration with a second coding, which is particularly different from the first coding.

[0088] In further exemplary embodiments, the use of the insert can include a step of completely removing all pins from the plurality of openings or coding openings. This allows the insert to be formed, for example, without any coding.

[0089] The insert and the test contactor, their exemplary, preferred and alternative embodiments, and their effects, relate equally to the use of the insert, and vice versa.

[0090] The present case always assumes a test element which, for example, has one or more coding openings which, in the test state and especially already in the state of the test element attached to the test area of ​​the insert, can engage with the pins of the insert which form the coding of the insert if they correspond to each other, or cannot engage if they do not correspond to each other, for example if the test element is twisted, or if the test element is not intended for testing and therefore does not have the appropriate coding openings.

[0091] In exemplary embodiments, several test elements can be arranged in a test module, wherein the test module has the coding openings which, in the test state, can be brought into engagement with the pin(s) of the insert. The test contactor can, in particular, be configured to comprise one or more inserts, and especially to reversibly arrange one or more inserts on a frame section. Each insert can form a coding for a test element, or several inserts together can form a coding for one or more test elements, in particular for a test module on which several test elements are arranged.

[0092] This advantageously enables particularly efficient testing of test elements. Furthermore, it can advantageously increase the number of different codings that are formed jointly by a corresponding plurality of deployments.

[0093] The present statements regarding the test element and its coding openings refer accordingly equally to a test module which has coding openings and on which, in particular, one or more test elements may be arranged.

[0094] The insert may in particular comprise or consist of a plastic, in particular a thermoplastic plastic.

[0095] In particular, the insert element, the base section, and / or the fastening means may be made of or consist of a plastic, in particular a thermoplastic plastic.

[0096] The insert, and in particular the insert element, the base section, and / or the fastening element, are advantageously simple and cost-effective to manufacture from plastic, and especially from thermoplastic plastic, and furthermore exhibit suitable elastic deformability. Moreover, the insert is advantageously designed essentially as an insulator, apart from the contact elements arranged in or on the insert, so that targeted electrically conductive contact of the test element can be ensured.

[0097] In exemplary embodiments, the insert, and in particular the insert element, the base section, and / or the fastening means, may comprise or consist of polyethylene (PE), polypropylene (PP), polycarbonate (PC), polyamide (PA), and / or polyetheretherketone (PEEK).

[0098] If the insert, and in particular the insert element, the base section, and / or the fastening element, contains or consists of polyetheretherketone, the insert is advantageously heat-resistant in addition to being particularly easy to manufacture, for example by injection molding. This heat resistance advantageously allows for a large number of consecutive or continuous tests to be performed on the test contactor, with the test being advantageously repeatable.

[0121] The in Fig. The representation of the test contactor 1 shown in Figure 15 can in particular correspond to a transport state of the test contactor 1 in which no printed circuit board 2 is arranged between the insertion section 20 and the support element 110.

[0122] Fig. Figure 16 shows another sectional view of a test contactor 1 according to an embodiment, in the closed state. The sectional view represents a section with a cutting plane that extends essentially in the vertical direction H, H' and in the longitudinal direction L, L'. The Fig. The test contactor 1 shown in Figure 16 can in particular be essentially the same as the test contactor 1, as shown in the Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 12, Fig. 13 and Fig. 15 shown, correspond. Furthermore, the test contactor 1 can be in Fig. 16 essentially the test contactor 1, as in the Fig. 1, Fig. 2 and Fig. 3 shown, corresponding to the test contactor 1 in the closed state, and wherein a circuit board 2 is arranged at the test contactor 1.

[0123] Compared to test contactor 1, as in Fig. As shown in 15, it is at test contactor 1, as in Fig. Figure 16 shows, in particular a printed circuit board 2 arranged at the test contactor 1. The printed circuit board 2 is arranged in a sandwich-like manner between the insert section 20 and the support element 110. Fig. 16 can in particular represent a test state of the test contactor 1.

[0124] Fig. Figure 17a shows a support element 110 according to one embodiment.

[0125] Fig. 17b and Fig. Figure 17c shows a sectional view of a support element 110 according to an embodiment, wherein the support element 110 is in particular the one shown in Fig. The support element 110 shown in 17a can correspond to the one shown in the Fig. 17a, Fig. 17b and Fig. The support elements 110 shown in 17c can in particular correspond to the respective support elements 110 as shown in the Fig. 1 to 7, 12, 13, 15 and 16 shown or arranged on the test contactors 1 shown there.

[0126] The one in the Fig. The test contactor 1 shown in Figures 1 to 7, 12, 13, 15, 16 and 17 represents an exemplary test contactor 1, which in particular has an insertion section 20 and a pressure section 80, wherein the insertion section 20 and the pressure section 80 are pivotably mounted relative to each other, in particular by means of an exemplary pivot joint 90 or by means of several pivot joints 90.

[0127] The one in the Fig. The test contactor 1 shown in Figures 1 to 7, 12, 13, 15, 16 and 17 has several test areas 5, which are only partially indicated with reference symbols in the figures for clarity. The insert section 20 has, in particular, a corresponding plurality of inserts 40, such that each insert 40 has a test area 5 to which a test element 10 can be attached.

[0128] The test element 10 can in particular be inserted into or attached to the insert 40, in particular being inserted into or attached to the insert 40 in such a way that the test element 10 is electrically conductively contacted with the contact elements 8, which are arranged at least partially in the insert 40, in the test state of the test contactor 1.

[0129] It is understood that although the test contactor 1 has, by way of example, a plurality of test areas 5 and inserts 40, for the electrically conductive contacting of a corresponding plurality of test elements 10, the test contactor 1 is not limited to this.In further exemplary embodiments, the test contactor 1 can have a plurality of test areas 5 and inserts 40 that differs from those shown in the figures, and / or a plurality of pressure elements 81 that differs from those shown in the figures, and / or a plurality of support elements 110 that differs from those shown in the figures, for example, a single insert 40 which accordingly has a single test area 5, and / or a single pressure element 81 which extends in the width direction B, B', for example, with substantially the same dimension as the insert 40 and / or as the test area 5 provided by the insert 40 for arranging a test element 10 on it, and / or the test contactor 1 can have a single support element 110.

[0130] Although the test contactor 1 therefore advantageously enables the simultaneous testing of a plurality of test elements 10, which may, for example, be arranged on a test module 12, another exemplary test contactor 1 can only test one, two, three, four, five, six, seven, eight, or a plurality of test elements 10 other than the one shown, simultaneously, in particular by means of a corresponding number of inserts 40, which in turn provide a corresponding number of test areas 5.

[0131] Accordingly, the inserts 40, which the insertion section 20 has and which are arranged in particular on the frame section 30 of the insertion section 20, can each be configured to form or have a test area 5 for a single test element 10. This advantageously ensures test element-specific testing by the test contactor 1.

[0132] The inserts 40 can be attached to the frame section 30 in a reversibly detachable manner, for example by means of screws, retractable clips, or similar.

[0133] The longitudinal direction L and the lateral direction B define, in particular, a substantially horizontal plane in which the test contactor 1, and especially the insertion section 20 of the test contactor 1, can be set up or positioned. This substantially horizontal plane can, in particular, correspond to a work surface during typical use of the test contactor 1.

[0134] The vertical direction H represents a direction essentially perpendicular to the horizontal plane spanned by the longitudinal direction L and the lateral direction B. The vertical direction H corresponds in particular to an up-down direction in a typical use of the test contactor 1, and in particular to an up-down direction in a typical use of the insert section 20 of the test contactor 1, and furthermore in particular to an up-down direction in a typical use of the insert 40 of the insert section 20.

[0135] If test contactor 1 is in a closed state, as for example in the Fig. As shown in Figures 4 to 7, 12, 13, 15 and 16, the width direction B' of the pressure section 80 coincides with the width direction B of the test contactor 1, the length direction L' of the pressure section 80 coincides with the length direction L of the test contactor 1, and the height direction H' of the pressure section 80, or the thickness direction of the pressure section 80, coincides with the height direction H, or top-bottom direction, of the test contactor 1, or is at least substantially parallel to each other. The width direction B of the test contactor 1 is, in particular, essentially parallel to the width direction B' of the pressure section 80, regardless of whether the test contactor 1 is in the open or closed state.

[0136] The respective directions are shown without a specific origin and serve to represent a relative position of the parts and sections of the test contactor 1 to each other.

[0137] The latitude direction B, the longitude direction L and the height direction H or the up-down direction H form in particular a right-handed system.

[0138] The width direction B' of the pressure section 80, the length direction L' of the pressure section 80 and the height direction H' of the pressure section 80 or the thickness direction H' of the pressure section 80 form in particular a right-handed system.

[0139] The longitudinal direction L' of the pressure section 80 and the lateral direction B' of the pressure section 80 define, in particular, a plane which, in the closed state of the test contactor 1, is essentially parallel to the plane defined by the lateral direction B and the longitudinal direction L of the test contactor 1. In the open state of the test contactor 1, as exemplified in the Fig. 1, Fig. 2 to Fig. As shown in Figure 3, the height direction H' and the thickness direction H' of the pressure section 80 are essentially perpendicular to the plane spanned by the longitudinal direction L' and the lateral direction B' of the test contactor 1. In particular, the height direction H' and the thickness direction H' of the pressure section 80 represent a direction along the thickness of the pressure section 80.

[0140] The pressure section 80 is pivotally mounted relative to the insertion section 20, in particular by means of one or more pivot joints 90. The pivot joint 90, as exemplified in the Fig. 1 to 7, 12, 13, 15, 16 and furthermore in particular in Fig. As shown in Figure 14c, it can in particular have a single rotational degree of freedom. This degree of freedom is provided by the pivot joint 90 for the pressure section 80, for pivoting relative to the insertion section 20.

[0141] This advantageously ensures a targeted and repeatable transition between the open state and the closed state, and in particular between the open state and the test state of the test contactor 1.

[0142] In further exemplary embodiments, and as shown in the figures, the test contactor 1 can comprise a plurality of pivot joints 90 by means of which the pressure section 80 is pivotably mounted relative to the insertion section 20. In particular, the test contactor 1 can comprise two pivot joints 90, which are spaced apart from each other in a direction parallel to the pivot axis SA. This ensures and improves the pivoting movement of the pressure section 80 and, consequently, a targeted and repeatable transition between the open and closed states.

[0143] The pivot axis SA of a respective pivot joint 90 is defined, in particular, essentially by an axial element 92 of the pivot joint 90. A restoring means 94 can, in particular, be arranged on the axial element 92. Specifically, a restoring means 94 can be arranged around the axial element 92, and by its arrangement on or around the axial element 92, form a pivot axis SA about which the pressure section 80 can pivot relative to the insertion section 20.

[0144] As in the Fig. 1 to 7, 12, 13, 15, 16 and furthermore especially in the Fig. 14a and Fig. As shown in Figure 14b, in particular the pressure section 80 has a fastening area 86 for fastening the axial element 92.

[0145] The fastening area 86 is formed in the longitudinal direction L' of the pressure section 80, particularly on a rear end face of the pressure section 80. The fastening area 86 has, in particular, an opening 87 which extends continuously through the pressure section 80 in the thickness direction H' of the pressure section 80. Adjacent to the opening 87, which extends through the pressure section 80 in the thickness direction H', on both sides in the width direction B' of the pressure section 80, is a cavity that is bounded or limited on one side in the thickness direction H' of the pressure section 80. This cavity is bounded or limited on one side in the thickness direction H' of the pressure section 80 by the first stop 88, which adjoins the opening 87 on one side in the width direction B', and by the second stop 89, which adjoins the opening 87 on the other side in the width direction B'.

[0146] As in the Fig. 1 to 7, 12, 13, 15, 16 and furthermore especially in the Fig. 14a and Fig. As shown in 14b, the first stop 88 and the second stop 89 can be arranged opposite each other essentially in the thickness direction H' of the pressure section 80.

[0147] As through the Fig. 1 to 7, 12, 13, 15, 16 shown and especially by the Fig. 14a and Fig. As illustrated in Figure 14b, the first stop 88 for an axial element 92 arranged at the mounting area 86 can form a stop in the thickness direction H' of the pressure section 80, and the second stop 89 for an axial element 92 arranged at the mounting area 86 can form a stop against the thickness direction H' of the pressure section 80.

[0148] This allows the swivel joint 90 to be advantageously mounted on the pressure section 80 without preload.

[0149] For example, the pivot joint 90 can be arranged or positioned in the area of ​​the opening 87 of the mounting area 86 such that the axial extent of the axial element 92 is approximately aligned with the thickness direction H' of the pressure section 80. The pivot joint 90 can then be rotated substantially about a direction parallel to the longitudinal direction L' of the pressure section 80. In particular, the pivot joint 90 can be rotated such that the axial element 92, in the thickness direction H' of the pressure section 80, abuts the first stop 88 and the second stop 89, or contacts one or both stops of the first and second stops 88, 89.In other words, the rotation of the pivot joint 90 relates in particular to a rotation of the pivot joint 90, wherein the axial extent of the axial element 92 of the pivot joint 90 is transformed or rotated from a state in which it is oriented substantially along the thickness direction H' to a state in which it is oriented substantially parallel to the width direction B' of the pressure section 80.

[0150] It is understood that, depending on the dimensions of the axial element 92 and the dimensions of the continuous opening 87 in the width direction B', the pivot joint 90 does not initially have to be aligned exactly with the thickness direction H' of the pressure section 80. For example, the pivot joint 90 can instead be arranged rotated in the continuous opening 87, for example already towards the target position in the mounting area 86, in particular towards the two stops 88, 89.

[0151] In exemplary embodiments, the rotation of the pivot joint 90 can be effected such that a second spring arm (not shown) of the return element 94 of the pivot joint 90 engages in the spring arm receptacle 85 of the pressure section 80. The second spring arm comprises, in particular, a means engaging in the spring arm receptacle 85, which comes to rest against the pressure section 80 within the spring arm receptacle 85. The second spring arm of the return element 94 of the pivot joint 90 can, in particular, be arranged projecting substantially tangentially from the axial element 92.Furthermore, the second spring arm of the restoring means 94 can be designed in such a complementary manner with the spring arm receptacle 85 that the second spring arm does not exert any force on the pressure section 80 in the open state of the test contactor 1, and in particular exerts an increasing force on the pressure section 80 during the transition to the closed state, i.e. an increasing force which is directed against the closing movement of the test contactor 1 or the pivoting movement towards the closed state of the test contactor 1.

[0152] The spring arm receptacle 85 can be arranged or formed in the thickness direction H' of the pressure section 80, particularly on a side of the pressure section 80 facing the test element 10 in the test state of the test contactor 1. Furthermore, the spring arm receptacle 85 can be closed or have a stop on a side of the pressure section 80 facing away from the test element 10 in the test state of the test contactor 1, in the thickness direction H' of the pressure section 80, for engaging the second spring arm of the return element 94, particularly when pivoting the pressure section 80 into the closed state of the test contactor 1.

[0153] The test contactor 1 can include one or more swivel joints 90 for pivotable mounting of the pressure section 80 relative to the insertion section 20. As shown in the Fig. Figures 1 to 7, 12, 13, 15 and 16 show that if the test contactor 1 comprises several pivot joints 90, the pivot joints 90 of the multiple pivot joints 90 can be spaced apart from each other essentially in a direction parallel to the pivot axis SA. This advantageously ensures a particularly stable and repeatable pivoting of the pressure section 80 relative to the insertion section 20.

[0154] As in the Fig. As shown in Figures 1 to 7, 12, 13, 15 and 16, the insert section 20 can, in particular, comprise a mounting area 22 for the base 98 of the pivot joint 90. Specifically, the frame section 30 of the insert section 20 can comprise the mounting area 22 for the base 98. Furthermore, the insert section 20 and the frame section 30 can, in particular, each comprise a mounting area 22 for each pivot joint 90.

[0155] The base 98 has, in particular, a receptacle for the axial element 92. As shown in the Fig. 1 to 7, 12, 13, 15 and 16 shown and in Fig. As illustrated in Figure 14c, the base 98 can, in particular, have a two-armed receptacle for the axial element 92. The two-armed receptacle comprises, in particular, two opposing holes designed to receive the axial element 92 along its axial extent. The axial extent of the axial element 92, with the restoring means 94 arranged thereon or around it, essentially defines the pivot axis SA, such that the pivot axis SA is essentially parallel to the axis of the axial extent of the axial element 92, and in particular is essentially coaxial with the axial element 92 arranged on the base 98.

[0156] In exemplary embodiments, one or both of the two opposing holes of the two-armed receptacle of the base 98 can be frictionally connected to the axial element 92. This allows the axial element 92 to be advantageously positioned precisely relative to the base 98. Furthermore, the assembly of the swivel joint 90 can be facilitated, since the axial element 92 is advantageously prevented from detaching from the base 98.

[0157] In further exemplary embodiments, the two opposing holes of the two-armed receptacle of the base 98 can form a clearance fit or transition fit with the axial element 92. This allows the axial element 92 and the restoring means 94 to be advantageously and easily attached to the base 98.

[0158] As in the Fig. 12, Fig. 14c and Fig. As shown in Figure 15, the base 98 can, in particular, have a receptacle for a first spring arm 96 of the restoring element 94. The receptacle of the base 98 for the first spring arm 96 can be an opening that extends through the entire base in the vertical direction H, or it can be an opening that does not extend completely through the base 98 in the vertical direction H. The restoring element 94 can be easily positioned on the base 98 by means of the opening for the first spring arm 96 before the axial element 92 is pushed through the restoring element 94 and received by the receptacle of the base 98, which can have two arms.

[0159] Furthermore, the mounting of the base 98 for the first spring arm 96 of the return element 94 advantageously allows for adjustment of the direction in which the second spring arm of the return element 94 (not shown in the figures) projects from the return element 94 or from the axial element 92 when mounted on the pressure section 80. This facilitates easy adjustment of the mounting of the pivot joint 90 on the pressure section 80, whereby the second spring arm of the return element 94 is inserted into the spring arm receptacle 85. Furthermore, the mounting is adjustable so that the pivot joint 90 with the axial element 92 can be advantageously attached without preload to the mounting area 86 of the pressure section 80, and the base 98, particularly after the axial element 92 has been attached to the pressure section 80, can be attached without preload to the mounting area 22 of the insert section 20 or the frame section 30.In particular, the base 98 can be attached without preload to the mounting area 22 of the insert section 20 or the frame section 30, especially in a relative position between pressure section 80 and insert section 20 or frame section 30, which corresponds to the open state of the test contactor 1.

[0160] A maximum open position of the open state between pressure section 80 and insertion section 20 or between pressure section 80 and frame section 30 can be set, for example, by a mutual stop between pressure section 80 and insertion section 20 or between pressure section 80 and frame section 30.

[0161] As in the Fig. 12 and Fig. As shown in Figure 13, the fastening area 22 for the base 98 can, in particular, have a step 23, especially if the fastening area 22 has a step 23 on both sides in the width direction B. The step 23 or the step 23 on both sides comprises, in particular, a section set back in the height direction H, through which the base 98 can be arranged at least partially in a form-fitting manner on the fastening area 22, especially if it can be arranged in a form-fitting manner on one side in the longitudinal direction L, and / or in a form-fitting manner on both sides in the width direction B.

[0162] This advantageously facilitates and improves the positioning of the base 98 for assembly, especially for pre-tension-free assembly, on the fastening area 22 for the base 98.

[0163] As in Fig. As illustrated in Figure 13, the fastening area 22 for the base 98 and the base 98 can include corresponding fixing means to ensure simple and, in particular, pre-tension-free fixing of the base 98 to the fastening area 22 for the base 22.

[0164] The mounting area 22 for the base 98 and the base 98 itself can, in exemplary embodiments, be fixed by positive locking and / or friction locking, for example by means of screws, by means of self-retaining clips, by means of cotter pins, by means of frictionally engaging bolts, by means of a bayonet fitting, or similar. In alternative embodiments, the mounting area 22 for the base 98 and the base 98 itself can be fixed by material locking, for example by means of gluing or welding, or similar.

[0165] In exemplary embodiments, and as in Fig. As illustrated in Figure 13, the base 98 can be fixed to the mounting area 22 for the base 98, in particular by means of one or more screws. If the mounting area 22 has the step 23, or the step 23 on both sides in the width direction B, a single screw or other single fixing means may advantageously suffice to fix the base 98 to the mounting area 22 for the base 98, since the positive locking advantageously limits or prevents rotation of the base 98 relative to the mounting area 22 for the base 98. If the base 98 is fixed by means of several fixing means, for example by means of several fixing means spaced apart from each other in the width direction B, for example by means of two screws spaced apart from each other in the width direction B, rotation of the base 98 relative to the mounting area 22 for the base 98 can advantageously be prevented.This makes it advantageous to adjust the pivot axis SA of the printing section 80 relative to the insertion section 20, and to adjust testing using the test contactor 1 with advantageous repeatability.

[0166] By pivoting the second spring arm (not shown) of the restoring means 94 with the pressure section 80, when pivoting the pressure section 80 into the closed state of the test contactor 1, relative to the first spring arm 96 of the restoring means 94, which is fixed in particular on the base 98 and / or on the mounting area 22 of the insertion section 20 or the frame section 30, a restoring force can advantageously be provided by the restoring means 94, which increases with increasing pivoting of the pressure section 80 into the closed position of the test contactor 1.

[0167] The restoring means 94 can in particular comprise a spring, such as a coil spring, which is arranged around the axial element 92. The spring can in particular comprise a first spring arm 96 and a second spring arm (not shown), each of which projects or extends substantially tangentially from the axial element 92. The first spring arm 96 is in particular a spring arm 96 facing the insertion section 20 or the frame section 30, which is configured to come into contact with or be received in the insertion section 20 or the frame section 30, and which is in particular configured to be fixed to the insertion section 20.The second spring arm is in particular a spring arm facing the pressure section 80, which is designed, in particular in the area of ​​the spring arm receptacle 85, to come into contact with the pressure section 80 or to be received therein, in order to move with the pressure section 80 in accordance with the in particular pivoted position of the pressure section 80.

[0168] The restoring means 94 advantageously allows a predetermined force to be set for bringing the test contactor 1 into the closed state, and in particular into the test state, which further advantageously prevents the test contactor 1 from accidentally or unintentionally closing, thereby in turn advantageously protecting the contact elements 8.

[0169] It is understood that the fastening areas 22, 86 for the pivot joint 90 can be configured, in particular in reverse, on the pressure section 80 and on the insertion section 20 or frame section 30. It is further understood that the pressure section 80 and the insertion section 20 can be connected by means of other pivot joints, in particular by means of other returnable pivot joints, than the one described in particular in Fig. The swivel joint shown in 14c can be pivotally coupled to each other at 90 degrees.

[0170] The swivel joint 90, which is particularly capable of self-returning, as in particular in Fig. Figure 14c illustrates, but advantageously allows for preload-free mounting on the test contactor 1, in particular on the pressure section 80 and on the insertion section 20.

[0171] As in the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 12, Fig. 13, Fig. 14a and Fig. As shown in Figure 14b, in exemplary embodiments, one of the insertion section 20 and the pressure section 80, in particular one of the frame section 30 and the pressure section 80, can have a projection 24 which is configured to engage in a groove 84 of the other of the insertion section 20 or frame section 30 and the pressure section 80. The engagement of the projection 24 in the groove 84 can, in particular, include engagement both in the open state and in the closed state of the test contactor 1.

[0172] The projection 24 can, in particular, project substantially in the vertical direction H of the insertion section 20, especially towards the pressure section 80, if the projection 24 is arranged or formed on the insertion section 20 or on the frame section 30. The projection 24 can be formed integrally with the insertion section 20, the frame section 30, or the pressure section 80, or can, in particular, comprise a bolt or a similar pin-shaped element.

[0173] The groove 84 can, in particular, comprise an opening facing the hinge joint 90 in the longitudinal direction L, L' on the insertion section 20 or on the pressure section 80. The groove 84 can extend substantially in the vertical direction H of the insertion section 20 if the groove 84 is arranged or formed on the insertion section 20, or it can extend substantially in the thickness direction H' of the pressure section 80 if the groove 84 is arranged or formed on the pressure section 80.

[0174] The projection 24 and the groove 84 can be arranged or configured to be spaced apart from a hinge joint 90, particularly in a direction that is essentially parallel to the pivot axis SA. In exemplary embodiments, the projection 24 and the groove 84 can be arranged between two pivot joints 90, particularly in a direction that is essentially parallel to the pivot axis SA of several pivot joints 90.

[0175] The projection 24 and the groove 84, through their mutual engagement, facilitate the assembly of the test contactor 1, for example, by allowing the pressure section 80, with the pivot joint(s) 90 attached to the pressure section 80 without preload, to be positioned on the insertion section 20 or on the frame section 30 of the insertion section 20 such that the projection 24 and the groove 84 engage. Subsequently, the base 98 of one or more pivot joints 90 can be easily attached to the mounting area 22 for the base 98.

[0176] The projection 24 and the groove 84 therefore advantageously provide an assembly aid, in particular an assembly guide.

[0177] Furthermore, in the exemplary case of a test contactor 1 with a single pivot joint 90, the projection 24 and the groove 84 can advantageously form a pivot guide, which in turn advantageously improves the repeatability of the tests carried out with the test contactor 1.

[0178] As in the Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 15 and Fig. As shown in Figure 16, the pressure section 80 can, in particular, have one or more pressure elements 81, which are attached to the pressure section 80 by means of one or more fixing means 83. The fixing means 83 advantageously allow the pressure element 81 to be inclined relative to the insertion section 20 when transitioning to the closed state and, in particular, to the test state, for example, to ensure uniform and, in particular, planar contact of a test element 10 arranged on the test area 5. The pressure element 81 can, in particular, be pre-tensioned towards the fixing means 83 by means of one or more pre-tensioning means 82 of the pressure section 80, so that the pressure element 81 reliably assumes an orientation or inclination specified by the fixing means 83.

[0179] This advantageously ensures uniform contact, particularly protecting contact elements 8, through the pressure section 80.

[0180] In alternative embodiments, the pressure section 80 can be formed essentially in one piece, and in particular in one piece with a pressure element 81 that projects towards the test element 10 in the test state. This makes the pressure section 80 advantageously easy to manufacture.

[0181] As in the Fig. As shown in Figures 1 to 3, 5, 6, 7, 12, 13, 15 and 16, the insert section 20 can comprise one or more inserts 40 which can be attached to a frame section 30, in particular detachably attached.

[0182] What next in the Fig. 5 and Fig. As illustrated in Figure 15, the insert 40 comprises a plurality of contact elements 8, which, without being limited to this, can be designed in particular as spring contact pins. The contact elements 8 of an insert 40 are configured to electrically contact a test element 10 in the test state of the test contactor 1. The electrically conductive contact can be established by the contact elements 8, for example, with a test station or with a printed circuit board 2.

[0183] In Fig. 3. Five test elements 10 are shown as examples, one test element 10 is shown partially, and one insertion 40 is shown to which no test element 10 is arranged or attached.

[0184] As exemplified in the sectional views in the Fig. 5, Fig. 6, Fig. 7, Fig. 15 and Fig. As illustrated in Figure 16, the insert 40 can have a test area 5 on its upper side in the vertical direction H, where the test element 10 can be positioned to make electrically conductive contact with the contact elements 8, which are arranged on or in the insert 40. The test area 5 can, in particular, be a region bounded in the vertical direction H, H' between the insert 40 and the pressure section 80 or between the insert 40 and the pressure element 81, where the test element 10 can be positioned and, in particular, inserted.

[0185] In the test state of the test contactor 1, in particular when the clamping means 100 is engaged with the complementary clamping means 32, the test contactor 1 is designed to press the test element 10 against the insert 40 by means of the pressure section 80, in particular by means of the pre-tensioned pressure element 81, in particular against the contact elements 8 of the insert 40, so that the test element 10 is or becomes electrically conductively contacted with the contact elements 8.

[0186] As especially in the Fig. 5, Fig. 6, Fig. 7, Fig. 8a, Fig. 8b, Fig. 9b, Fig. 9c, Fig. 10, Fig. 11a, Fig. 11b, Fig. 11c, Fig. 15 and Fig. As shown in Figure 16, the insert 40 can in particular be designed in multiple parts and may have at least one insert element 50, one or more fastening means 42, and a base section 60.

[0187] The insert element 50 can be attached to the base section 60, in particular by means of one or more fastening means 42. The fastening means 42 can in particular be an elastically resilient fastening means 42.

[0188] The base section 60, as in particular in Fig. As illustrated in 15, it can be attached to the frame section 30 of the insert section 20 by means of a connecting means 69, in particular it can be detachably attached.

[0189] The insert element 50 is, in particular, a part of the insert 40 facing the test element 10 in the test state of the test contactor, i.e., in particular, an upper part of the insert 40 in the top-bottom direction H. The base section 60 is, in particular, a part of the insert 40 facing away from the test element 10 in the test state of the test contactor, i.e., in particular, a lower part of the insert 40 in the top-bottom direction H.

[0190] The base section 60 can be configured, in particular, to receive the insert element 50 section by section. The base section 60 can, for example, be trough-shaped. The base section 60 can be configured, in particular, to receive the insert element 50 between opposing side surfaces 57 of the base section 60, especially side surfaces 57 of the base section 60 that are essentially opposed to each other in the longitudinal direction L and / or essentially in the lateral direction B, at least section by section.

[0191] The insert element 50 can, for example, be trough-shaped, in particular be trough-shaped complementarily to the base section 60, in particular such that the mutually facing side surfaces 55, 57 of the insert element 50 and the base section 60 adjoin each other, and, for example, have a spacing in the adjacent direction of less than about 2 mm, in particular of less than about 1.4 mm, and furthermore, in particular of less than about 1 mm, for example, in the range of about 0 mm to about 2 mm, in particular in the range of about 0.2 mm to about 1.4 mm, and furthermore, in particular in the range of about 0.2 mm to about 1 mm.

[0192] Thus, the insert element 50 can advantageously be guided through the base section 60, in particular essentially in the top-bottom direction H. This allows the insert element 50 to advantageously form a guide for the contact elements 8 that is movable in the top-bottom direction H, and accordingly a support and / or protection for the contact elements 8.

[0193] As particularly through the Fig. 8a, Fig. 8b, Fig. 9a, Fig. 9b, Fig. 9c and Fig. As illustrated in Figure 10, the insert 40 can, in particular, have an elastically resilient fastening element 42. Specifically, the insert 40 can have only a single fastening element 42 to attach the insert 50 to the base section 60. This makes it advantageously easy to mount and dismount the insert 50 on the base section.

[0194] The insert element 50 can, in particular, comprise several holes 51 configured to partially surround the contact elements 8, especially to partially surround an upper end of the contact elements 8. The base section 60 can, in particular, comprise several holes 61 configured to receive the contact elements 8. The holes 61 of the base section 60 and the holes 51 of the insert element 50 are, in particular, arranged or configured to be substantially aligned with each other in the top-bottom direction H.

[0195] The holes 51, 61 in the insert element 50 and the base section 60 advantageously support and, in particular, protect the contact elements 8, thus advantageously improving the service life of the contact elements 8 and, consequently, of the test contactor 1. The holes 51, 61 can, in particular, be arranged or formed continuously in the insert element 50 or in the base section 60, and, in particular, extend substantially parallel to the top-bottom direction.

[0196] As through the Fig. 8b, Fig. 9b, Fig. 9c and Fig. As illustrated in Figure 10, the insert element 50 can have a translational degree of freedom, essentially in the up-down direction H, relative to the base section 60 by means of the fastening means 42. The translational degree of freedom, essentially in the up-down direction H, can be limited, in particular, by means of the fastening means 42, as shown in the example in Figure 10. Fig. The limit position shown in 9b is illustrated, in which a stop section 47 of the fastening means 42 is in contact with or abuts a complementary stop 63 of the base section 60.

[0197] The fastening element 42 can, in particular, have a substantially circular stop section 47, from which an engagement section 43 extends in the top-bottom direction H. The stop section 47 can, in particular, have a larger cross-section or diameter than an opening 62 of the base section 60 in the region of the complementary stop 63 of the base section 60. In other words, the complementary stop 63 of the base section 60 can, in particular, provide a positive fit for the stop section 47 of the fastening element 42, especially a positive fit substantially in the top-bottom direction H, so that the translational degree of freedom of the insert element 50 is advantageously limited.

[0198] The insert element 50 can in particular have a shoulder 56 in order to engage with the engagement section 43 of the fastening means 42 in a state attached to the base section 60.

[0199] In exemplary embodiments, the insert element 50 can, in particular, have a collar 54 which extends substantially in a hollow cylindrical shape in the top-bottom direction H, and especially extends substantially downwards in the top-bottom direction H from the insert element 50. The collar 54 can, in particular, have a smaller outer diameter than the inner diameter of the opening 62 of the base section 60 in the region of the complementary stop 63 of the base section 60. This makes it advantageously easy to pre-assemble the insert element 50 with the collar 54 on the base section 60, which further facilitates connection with the fastening means 42.

[0200] The collar 54 can in particular have the shoulder 56 for the engagement of the engagement section 43 of the fastening means 42.

[0201] In exemplary embodiments, the shoulder 56 can be arranged or formed in a central section of the collar 54 along the top-bottom direction H. This allows the fastening element 42 to advantageously engage in the insert element 50, and in particular in the collar 54 of the insert element 50, without projecting upwards from the collar 54 in the top-bottom direction H, thereby ensuring an advantageously large test area 5 for a test element 10.

[0202] The fastening element 42 can be rotatably engaged with the insert element 50, i.e., rotatably about the central axis of the opening 52 of the insert element 50. This advantageously simplifies the connection of the insert element 50 with the fastening element 42. In other words, the connection between the insert element 50 and the fastening element 42 can, in particular, have one rotational degree of freedom, specifically one rotational degree of freedom substantially about the central axis z of the opening 52 of the insert element 50.

[0203] The rotational degree of freedom of the insert element 50 relative to the fastening element 42 can be restricted or blocked, in particular, by mutually facing side surfaces 55, 57 of the insert element 50 and the base section 60, at least for the insert element 50 or only for the insert element 50. This allows the fastening element 42 and its connection with the insert element 50 to be advantageously designed simply, wherein the fastening element 42 forms a limitation of one translational degree of freedom of the insert element 50, and the base section 60, advantageously independently, forms a limitation of one rotational degree of freedom of the insert element 50.

[0204] The insert element 50 and / or the base section 60 can have an opening 52, 62, which is arranged or formed essentially at the geometric center Z of the insert element 50 or the base section 60, respectively. This allows the insert element 50 to be advantageously guided uniformly through the fastening means 42 and the adjacent side surfaces 57 of the base section 60, in particular essentially in the top-bottom direction H.

[0205] The fastening means 42 can in particular have several spring arms 44 which extend essentially in the top-bottom direction H from the stop section 47 of the fastening means 42, for example two, three, four, five, six, or more spring arms 44.

[0206] The spring arms 44 each have a projection 45 that extends essentially perpendicularly outwards from the central axis z, in particular to engage with the shoulder 56 of the insert element 50. In the engaged state of the respective spring arm 44, the spring arm 44 is in a relaxed or elastically restored state. By deforming the spring arms 44 towards the central axis z, the fastening element 42 can be detached from the insert element 50.

[0207] The spring arms 44 of the fastening means 42 can be separated from one another, in particular by a recess 46, wherein the recess 46 separates the spring arms 44 substantially along the top-bottom direction H. The recess 46 can additionally or alternatively include a central hole through the fastening means 42, so that the spring arms 44 are arranged at least partially opposite one another, particularly with respect to a central axis z through the hole or through the recess 46.

[0208] In exemplary embodiments, the fastening means 42 can in particular comprise exactly two opposing spring arms 44, whereby the fastening means 42 can advantageously be easily connected to and detached from the insert element 50.

[0209] As especially in the Fig. 6 and Fig. As shown in Figure 10, the use of 40 can include one or more prestressing devices 58.

[0210] The prestressing device(s) 58 can be arranged or received at least partially in the base section 60 of the insert. Furthermore, the prestressing device(s) 58 can be configured, in particular, to prestress the insert element 50 away from the base section 60, i.e., to prestress the insert element 50 essentially upwards in a top-bottom direction. The prestressing device(s) 58 can be configured, in particular, to prestress the insert element 50 upwards or towards the test element 10 in the test condition such that the insert element 50, in the open state, is in the upper limit position defined by the fastening device 42, as is particularly evident in Fig. 9b is shown, arranged.

[0211] This allows the contact elements 8 to be advantageously supported and protected by the insert element 50 in the open state of the test contactor 1, for example by the holes 51 of the insert element 50 surrounding the contact elements 8 at least partially, and / or by the insert element 50 projecting upwards further than the upper ends of the contact elements 8 arranged on the insert 40.

[0212] When the test contactor 1 is pivoted from the open state to the closed state or to the test position, the test element 10, pressed by the pressure section 80 or by the pressure element 81 of the pressure section 80, advantageously first comes into contact with the insert element 50. Only through further pressure towards the closed state or to the test position does the test element 10 come into contact with the contact elements 8 by pressing the pressure section 80 or the pressure element 81. This advantageously reduces the initial pressure on the contact elements 8. Furthermore, accidental or unintentional direct contact with the contact elements 8 in the open state of the test contactor 1 is advantageously prevented, and the contact elements 8 are thus protected.

[0213] The preloading means 58 can, in particular, be elastically restorable preloading means 58 and, for example, comprise one or more springs, especially coil springs, and / or one or more elastomeric elements. In exemplary embodiments, the preloading means 58 can be arranged distributed around the geometric center Z of the insert 40 or around the geometric center Z of the insert element 50.

[0214] This allows the insert element 50 to be advantageously arranged on the insert 40 facing the test element 10 with preload, in particular to be arranged on the insert 40 with preload uniformly facing the test element 10.

[0215] As especially in the Fig. 8a, Fig. 8b, Fig. 10, Fig. 11a, Fig. 11b and Fig. As shown in Figure 11c, the insert 40 can comprise several openings 67 or coding openings 67. The coding openings 67 are designed in particular to be fitted with at least one pin 68, especially such that the at least one pin 68 is partially received in a coding opening 67 and partially projects upwards in the top-bottom direction H, in particular facing the test element 10 in the test state.

[0216] By installing or arranging one or more pins 68 in the multiple coding openings 67, the insert 40, and in particular the insertion section 20, can have a test element-specific coding. In other words, the coding is formed by one or more projections or by a coding pattern of projections formed by the one or more pins 68 arranged in the coding openings 67.

[0217] The Fig. 11a, Fig. 11b and Fig. Figure 11c shows exemplary codings or coding patterns using a pin 68 arranged in a coding opening 67. The ones in the Fig. 11a, Fig. 11b and Fig. The exemplary codings shown in Figure 11c can be combined with one another to form further codings or coding patterns. In particular, more than one pin 68, and especially different pins 68, can be arranged in the coding openings 67.

[0218] In Fig. Figure 3 shows examples of some codings 14 or coding recesses 14 of a test element 10 or of a test module 12, on which several test elements 10 are arranged. For clarity, only some of the codings 14 or coding recesses 14 in the figures are labeled with reference symbols.

[0219] What's next in Fig. As shown by way of example in Figure 3, the coding openings 67 of the inserts 40 can be fitted with a pin 68, in particular with different pins 68. By fitting several coding openings 67 with different pins 68, for example by means of pins 68 of different cross-sections or diameters, the insert 40 or the insertion section 20 can have a coding for a test element 10 or a test module 12 on which several test elements 10 are arranged. By means of the different pins 68, the insert 40 or the insertion section 40 can have a coding for a test element 10 or for a test module 12 which prevents the attachment or insertion of a test element 10 or test module 12 in a twisted position in the plane, i.e., for example, prevents it from being rotated by 180° about a substantially parallel to the vertical direction H, and / or which prevents the attachment or insertion of a test element 10 or test module 12 in a twisted position in the plane.Test module 12 is prevented from being turned upside down, i.e., rotated by 180° to be essentially parallel to the width direction B.

[0220] This advantageously prevents incorrect insertion of test elements 10 and / or test modules 12, thereby further improving the test accuracy of the test contactor 1 and the durability of the contact elements 8, and correspondingly of the test contactor 1, since a potentially undesirable or even harmful insertion and contacting of the contact elements 8 by the protruding pins 68 is prevented.

[0221] The coding openings 67 can in particular be arranged on a coding section 66 of the base section 60, in particular on coding sections 66 of the base section 60 that are essentially opposite each other in the longitudinal direction L.

[0222] In exemplary embodiments, the coding openings 67 can be arranged or designed asymmetrically with respect to a parallel to the width direction B on the insert 40, i.e., asymmetrically with respect to a mirror axis parallel to the width direction B and passing through the center Z.

[0223] This allows a coding to be advantageously provided by a single pin 68, which prevents the attachment or insertion of a test element 10 or test module 12 upside down, i.e., which prevents the attachment or insertion of a test element 10 or test module 12, for example, rotated by 180° about an essentially parallel to the width direction B.

[0224] In further exemplary embodiments, the coding openings 67 can be arranged or formed asymmetrically with respect to a point symmetry on the insert 40, i.e., asymmetrically with respect to an axis of symmetry running along the central axis z or asymmetrically with respect to a point conceived on the central axis z that lies in a plane of the coding sections 66 of the base section 60.

[0225] For example, the insert 40 can include coding sections 66 opposite each other in the longitudinal direction L, comprising an even number of coding openings 67 on one side and an odd number of coding openings 67 on the other side.

[0226] By appropriately asymmetrically placing or arranging pins 68 in the coding openings 67 which are arranged or formed asymmetrically with respect to point symmetry, it is advantageous to prevent the attachment or insertion of a test element 10 or test module 12 in a twisted position in the plane, i.e., for example, to prevent the attachment or insertion of a test element 10 or test module 12 rotated by 180° about a substantially parallel to the height direction H.

[0227] In exemplary embodiments, pairs of coding openings 67 arranged opposite each other in the longitudinal direction L can have the same cross-section or diameter. This advantageously ensures the simple formation of a coding pattern or a coding facing the test element 10, for which, for example, one pin 68 or a plurality of pins 68 of the same predetermined diameter or cross-section suffices.

[0228] In further exemplary embodiments, coding openings 67, which are arranged on the same coding section 66, i.e., are not arranged opposite each other in the longitudinal direction L, can have different cross-sections or diameters. This advantageously enables the reliable formation of a coding pattern or a coding facing the test element 10, which prevents incorrect arrangement or insertion of a test element 10 or test module 12.

[0229] As through the Fig. 8a, Fig. 8b, Fig. 10, Fig. 11a, Fig. 11b and Fig. As further shown in Figure 11c, the insert 40 can, in particular, have fixing means 70, especially if the base section 60 of the insert 40 is formed in multiple parts, and in particular has a base section 64 extending upwards and downwards in the direction H and a base section 65 extending downwards in the direction H. The fixing means 70 can, but are not limited to, include in particular holes, positioning means such as bolts, and screw connections.

[0230] This allows the upper and lower base sections 64, 65 to be easily manufactured, and in particular the opening 62 in the base section 60 for the upper and lower base sections 64, 65 to be easily introduced or manufactured.

[0231] In alternative embodiments, the base section 60 can be formed essentially in one piece. This advantageously allows for precise and, in particular, simple production of a continuous alignment of the holes 61 for receiving the contact elements 8.

[0232] As in the Fig. 1, Fig. 2, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 12, Fig. 13, Fig. 15 and Fig. As shown in Figure 16, the test contactor 1 can in particular comprise a support element 110, especially a support element 110 as shown in the Fig. 17a, Fig. 17b and Fig. 17c shown.

[0233] The test contactor 1 can, in particular in the transport state of the test contactor 1, in the open state of the test contactor 1, in the closed state of the test contactor 1, and / or in the test state of the test contactor 1, comprise one or more support elements 110.

[0234] The transport state of the test contactor 1 is, in particular, a state in which the support element 110 is arranged on the test contactor 1, and in particular in which the support element 110 is connected to the insertion section 20, especially from below in the top-bottom direction H. The transport state of the test contactor 1 is furthermore, in particular, configured in such a way that no printed circuit board 2 is arranged between the insertion section 20 and the support element 110, or no printed circuit board 2 is arranged on the test contactor 1.To ensure safe transport of the test contactor 1 in the transport state, the transport state can in particular include a closed state of the test contactor 1, i.e. a state in which the pressure section 80 is pivoted towards the insertion section 20, in particular pivoted such that the clamping means 100 and the complementary clamping means 32 of the pressure section 80 and the insertion section 20 are engaged.

[0235] Alternatively, the test contactor 1 can also be transported in the open state, for example stacked in the open state.

[0236] The test state of the test contactor 1 is, in particular, a state in which the support element 110 is arranged on the test contactor 1, and in particular in which the support element 110 is connected to the insertion section 20, especially from below in the top-bottom direction H. The test state of the test contactor 1 is furthermore, in particular, configured in such a way that a test element 10 is arranged on the insertion section 20, the test contactor 1 is in the closed state, and optionally a printed circuit board 2 is arranged between the insertion section 20 and the support element 110.

[0237] The support element 110 can comprise one or more projecting sections 112, which extend from a side of the support element 110 facing the insertion section 20, essentially in the top-bottom direction H. The projecting section(s) 112 can be arranged or formed in the longitudinal direction L, particularly centrally, on the support element 110. On the outer side in the longitudinal direction L, the support element 110 can, in particular, have one or more fastening means 115, which, for example, can be at least partially received in the support element 110. The fastening means 115 can, in particular, be received in the support element 110 such that, in the test condition, none of the fastening means 115 projects downwards in the top-bottom direction H from the support element 110. This advantageously allows the test contactor 1 to be positioned securely on a work surface.

[0238] The support element 110 can comprise one or more recessed sections 114, which are recessed on a side of the support element 110 facing the insertion section 20, essentially in the top-bottom direction H, and in particular recessed relative to the one or more projecting section(s) 112.

[0239] Projecting sections 112 and recessed sections 114 can, in exemplary embodiments, be configured to alternate with one another. Accordingly, the support element 110 can provide one or more cavities 116, particularly between the projecting sections 112, and especially on a side facing the insertion section 20 or the insert 40 of the insertion section 20. The cavities 116 are areas bounded, in particular from below, essentially in the top-bottom direction H by the support element 110, especially by the recessed section(s) 114. In other words, the cavities 116 are areas protected, in particular by the support element 110. Optionally, the cavities 116 can also be bounded, in particular laterally, essentially in the longitudinal direction L and / or in the lateral direction B, by the support element 110, especially by the projecting section(s) 112.

[0240] The alternating arrangement of the projecting sections 112 and the recessed sections 114 advantageously creates a labyrinthine protective barrier on the lower side of the insert section 20 or the insert 40 in the top-bottom direction H. This labyrinthine barrier is configured in particular to prevent direct access to the contact elements 8 from below, and especially to make direct access to the contact elements 8 from a downward angle more difficult or impossible.

[0241] In exemplary embodiments, the projecting sections 112 can be arranged on the support element 110 such that they do not align with the contact elements 8 in the top-bottom direction H. In particular, the projecting sections 112 can be arranged on the support element 110 such that they abut an alignment of the contact elements 8 in the top-bottom direction H in the longitudinal direction L and / or in the lateral direction B.

[0242] This advantageously prevents the contact elements 8 from being pressed by the support element 110 during transport. Furthermore, during testing, it advantageously ensures support for the insert 40, and in particular for a printed circuit board 2 arranged below the insert 40, which is pressed by the contact elements 8 during testing and may be subjected to bending stress and, in particular, bent. Thus, the support element 110 is advantageously functionally integrated and can advantageously improve the service life of the contact elements 8, the printed circuit board 2, and especially the test contactor 1.

[0243] The support element 110 can have one or more stepped contours 118, in particular at at least two spaced-apart locations of the support element 110, especially on two longitudinally L outer sections of the support element 110. The stepped contour(s) 118 can project towards the insertion section 20, in particular on a side facing the insertion section 20 in the transport and test conditions. The insertion section 20, and in particular the frame section 30 of the insertion section 20, can have stepped sections 34 complementary to the one or more stepped contours 118, in particular on a top-bottom H lower side of the insertion section 20.

[0244] The one or more stepped contours 118 together with the stepped sections 34 advantageously enable a positive locking and therefore particularly secure positioning of the support element 110 relative to the insertion section 20 during assembly, and accordingly facilitates the assembly of the test contactor 1 for the transport condition.

[0245] The support element 110 can further comprise one or more fastening means 115 for attachment to the insert section 20, in particular for attachment to the frame section 30 of the insert section 20. The fastening means 115 can, for example, comprise a screw connection, a retractable clip, and / or a friction-fit bolt. The fastening means 115 can, in particular, be at least partially incorporated in the support element 110 and, in particular, be arranged in the top-bottom direction H below the stepped contours 118. In exemplary embodiments, the fastening means 115 can be arranged in the support element 110 in a captive manner, for example by means of a projection, a retaining ring, a locking pin, or the like.

[0246] Fig. 18a and Fig. Figure 18b shows a flowchart of a use of an insert 40 according to one embodiment.

[0247] The use of an insert 40, as exemplified in the flowchart in Fig. As set out in 18a, this may in particular include the following steps: S10: Deployment of Unit 40; S20: Detaching the fastener 42 from the insert element 50; and S30: Removing the insert element 50 from the base section 60.

[0248] Steps S10, S20, and S30 can be performed in precisely this order. The use of insert 40 can refer specifically to an insert 40 as described herein and as particularly relevant in connection with the Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 8a, Fig. 8b, Fig. 9a, Fig. 9b, Fig. 9c, Fig. 10, Fig. 11a, Fig. 11b, Fig. 11c, Fig. 15 and Fig. 16 shown and described.

[0249] Following step S30, insert 40 can be used, for example: - include a step of adjusting and / or setting and / or replacing one or more preload devices 58; and / or - include a step of adjusting and / or setting and / or replacing one or more contact elements 8.

[0250] Furthermore, the use of the insert 40 may include a step of attaching another insert element 50 to the base section 60 by means of the fastening means 42, or a step of reattaching the insert element 50 to the base section 60 by means of the fastening means 42.

[0251] This makes the insert 40 advantageously adjustable for a test element 10 in an application-specific manner, advantageously adjustable for a specific test, for example for a test with predetermined force and / or pressure profile, and advantageously allows one or more contact elements 8 to be easily exchanged.

[0252] The use of an insert 40, as exemplified in the flowchart in Fig. As set forth in 18b, the following steps may in particular include: S110: Deployment of Unit 40; and S120: Arranging one or more pins 68 in at least one opening 67 of the plurality of openings 67 to form a coding facing the test element 10 in the test state.

[0253] Steps S110 and S120 can be performed in precisely this order. The use of insert 40 can refer in particular to an insert 40 as described herein and as specifically in connection with the Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 8a, Fig. 8b, Fig. 9a, Fig. 9b, Fig. 9c, Fig. 10, Fig. 11a, Fig. 11b, Fig. 11c, Fig. 15, Fig. 16 and Fig. 18a shown and described.

[0254] Following step S120, insert 40 can be used, for example: - a step of removing one or more of the pins 68 from at least one opening 67 of the plurality of openings 67, to form a further coding facing the test element 10 in the test state, which is different from the previous coding; and / or - a step of arranging one or more of the pins 68 in at least one opening 67 of the plurality of openings 67, to form a further coding facing the test element 10 in the test state, which is different from the previous coding.

[0255] This makes the insert section 20 or the insert 40 advantageously adjustable for a test element 10 or for a test module 12, whereby it is advantageously possible to prevent incorrect arrangement of the test element 10 or the test module 12, which has a predetermined coding by means of one or more coding recesses 14, on the insert section 20 or on the insert 40.

[0256] Fig. Figure 19 shows a flowchart of a process for manufacturing a test contactor 1.

[0257] The procedure for manufacturing a test contactor 1, as exemplified in the flowchart in Fig. 19, as reproduced, may in particular include the following steps: S210: Providing an insertion section 20 with a pressure section 80 which is pivotably mounted on the insertion section 20, wherein the insertion section 20 comprises a test area 5 to which the electrically conductive test element 10 can be attached, and which comprises contact elements 8 which are designed to electrically contact the electrically conductive test element 10 in the test state of the test contactor 1, wherein the pressure section 80 is designed to press the electrically conductive test element 10 against the multiple contact elements 8 in the test state of the test contactor 1; S220: Providing a support element 110; and S230: Connecting the support element 110 to the insert section 20 in such a way that the support element 110 forms a protection for the contact elements 8.

[0258] Steps S210, S220, and S230 can be performed in precisely this order. The fabrication of test contactor 1 can refer specifically to a test contactor 1 as described herein and as particularly evident in connection with the Fig. Items 1 to 7, 12, 13, 15 and 16 are shown and described.

[0259] Step S230 of connecting the support element 110 with the insert section 20 can be carried out in particular such that no printed circuit board 2 is arranged between insert section 20 and support element 110, or such that no printed circuit board 2 is arranged contacting the contact elements 8 at the test contactor 1.

[0260] The test contactor 1 produced in this way represents, in particular, a test contactor 1 in its transport state. The transport state can, in particular, be a closed state of the test contactor 1. The transport state of the test contactor 1 can also be a state of the test contactor 1 in which no test element 10 is arranged on the insertion section 20 and / or no printed circuit board 2 is arranged on the insertion section 20.

[0261] The transport state of the test contactor 1, wherein the support element 110 is connected to the insertion section 20, in particular from below in the top-bottom direction H, advantageously represents a state in which the contact elements 8 are protected. The contact elements 8 are protected in such a way that direct access to the contact elements 8, particularly from below, is prevented by the support element 110.

[0262] The connection of the support element 110 to the insertion section 20 in such a way that the contact elements 8 are protected, in particular in the top-bottom direction H from below, need not include a hermetic shielding of the contact elements 8, but in particular includes preventing direct access essentially from below, for example by the hand of a user, or by a tool commonly used for handling test contactors.

[0263] This advantageously protects the contact elements 8. In conjunction with the insert 40 and the insert element 50, which is pre-tensioned upwards in the top-bottom direction H, and / or in conjunction with the closed state of the test contactor 1, wherein the clamping means 100 is engaged with the complementary clamping means 32, the contact elements 8 can also advantageously be protected at the top, and the test contactor 1 can be configured to be advantageously durable.

[0264] Following step S230, the test contactor 1 can be used, in particular, by releasing the support element 110, arranging a printed circuit board 2 on the insertion section 20 such that it makes electrically conductive contact with the contact elements 8, and connecting the support element 110 to the insertion section 20 such that the printed circuit board 2 is supported by the support element 110. This advantageously prepares the test contactor 1 for use in a test with a test element 10 or test module 12 arranged or to be arranged on the insertion section 20, thereby advantageously improving the durability of the printed circuit board 2 and the repeatability of the tests performed with the test contactor 1.

[0265] Fig. 20a and Fig. Figure 20b shows a flowchart of a use of a support element 110 according to one embodiment.

[0266] The use of a support element 110, as exemplified in the flowchart in Fig. 20a, relates in particular to the use of a support element 110 for a test contactor 1 for testing an electrically conductive test element 10 for protecting contact elements 8 of the test contactor 1 during transport.

[0267] The use of support element 110, as in Fig. 20a, as exemplified, may in particular include the following step: S310: Connecting the support element 110 to the test contactor 1 without an intermediate circuit board 2.

[0268] The use of the support element 110 may relate in particular to a test contactor 1 and / or a support element 110, as described herein and as particularly in connection with the Fig. Items 1 to 7, 12, 13, 15, 16 and 19 are shown and described.

[0269] The support element 110 allows the contact elements 8 to be advantageously protected, in particular by connecting the support element 110 from below in the top-bottom direction H with the insert section 20, and in particular essentially from below, thereby further advantageously improving the durability of the contact elements 8 and, accordingly, of the test contactor 1.

[0270] The use of a support element 110, as exemplified in the flowchart in Fig. 20b, may in particular include the following steps: S410: Detaching the support element 110 from the test contactor 1; S420: Positioning a printed circuit board 2 at the test contactor 1; and S430: Connecting the support element 110 to the test contactor 1, such that the circuit board 2 is supported by the support element 110 in a test state of the test contactor 1.

[0271] Steps S410, S420, and S430 can be performed in precisely this order. The use of the support element 110 can refer in particular to an insert 40, as described herein and especially in connection with the Fig. 1 to 7, 12, 13, 15, 16, 19 and 20a are shown and described.

[0272] As shown in the flowcharts in the Fig. 20a and Fig. As highlighted in 20b, the present support element 110 is advantageously designed to be functionally integral both for protecting contact elements 8, particularly in the transport state of the test contactor 1, and for supporting a printed circuit board 2, particularly in the test state of the test contactor 1, wherein a pressure section 80 presses a test element 10 against the contact elements 8, and the contact elements 8 in turn presses against the printed circuit board 2.

[0273] Furthermore, the present support element 110 facilitates the assembly of the test contactor 1 into the test state, since all necessary fastening elements 115 for connecting the support element 110 to the insert section 20 can already be present for connecting the support element 110 in the transport state. Accordingly, loose assembly parts or loose fastening elements 115 can be advantageously avoided.

[0274] Fig. Figure 21 shows a flowchart of a process for manufacturing a test contactor 1.

[0276] Steps S530, S540 and S550 may alternatively include, in particular: - Providing at least one pivot joint 90, which comprises an axial element 92, a restoring means 94 and a base 98, wherein the at least one pivot joint 90 is configured to pivotally couple the pressure section 80 to the insert section 20 in a restorable manner, and wherein one of the insert section 20 and the pressure section 80 has at least one fastening area 22, 86 for the axial element 92 of the at least one pivot joint 90, and wherein the other of the insert section 20 and the pressure section 80 has at least one fastening area 22, 86 for the arrangement of the base 98 of the at least one pivot joint 90, - preload-free arrangement of the axial element 92 of the at least one pivot joint 90 in the at least one fastening area 22, 86 of one of the insert section 20 and the pressure section 80; and - pre-tension-free arrangement of the base 98 of at least one pivot joint 90 on or in the fastening area 22, 86 of the other of the insertion section 20 and the pressure section 80.

[0277] Steps S510, S520, S530, S540, and S550 can be performed in whole or in part, and in particular in this exact order. The fabrication of test contactor 1 can refer in particular to a test contactor 1 as described herein and as particularly in connection with the Fig. 1 to 7, 12, 13, 15, 16, 19, 20a and 20b are shown and described.
