Description

The invention relates to a socket for receiving an electrical component and is used in particular for the inclusion of capacitors application.

From the publication DE 20 2015 105 993 U1 is known a spring clamp. The spring-loaded terminal has a housing, a current bar, a clamping spring and a spring opener, wherein the housing has an insertion opening for an electrical conductor. The clamping spring and the current bar are arranged in the housing such that an electrical conductor inserted into the housing through the insertion opening can be clamped against the current bar by means of a clamping region of the clamping spring. The spring opener has an operating region which is accessible from outside the housing and a pressing region and is movably mounted.

The housing has a guide surface on which the spring opener abuts with a sliding surface, wherein the guide surface and the sliding surface are configured and arranged relative to each other, that the application of force to the actuating region in the predetermined direction movement of the spring opener with a movement component transverse to the predetermined Direction of the application of force to the actuation area causes.

The spring clamp described only relates to the inclusion of electrical conductors in the form of wires. A connection to a printed circuit board or an automated assembly is not provided.

The publication DE 10 2014 117 062 A1 describes another spring terminal with a current bar, a clamping spring and a clamping portion of the clamping spring. According to the document it is provided that the clamping spring has a bearing area on which an actuating element is pivotally mounted by a bearing portion of the actuating element engages around the bearing area of the clamping spring and thereby supported on this. This solution is also intended for cores and does not allow assembly of the spring terminal with an electrical component, in particular a capacitor.

In the publication DE 10 2008 048 087 A1 is described an electrical device with spring clamp and their use for a printed circuit board. It is described a multi-part electrical device with a circuit board and a spring terminal for clamping an electrical conductor. The spring-loaded terminal acts with its clamping area substantially in the direction of the circuit board. The electrical conductor is clamped between the printed circuit board and the spring terminal. The circuit board is used only for receiving wires of a cable. A simplified assembly by means of electronic components is not known.

The object of the invention is to develop a socket for receiving an electrical component, which has a simple construction and simplifies and accelerates the assembly of an electrical component on a circuit board / board. Thus, the cost of mounting a capacitor on a circuit board / board is reduced.

This object is achieved with the characterizing features of the first protection claim.

Advantageous embodiments emerge from the subclaims.

The invention relates to a socket for receiving an electrical component, in particular for receiving a capacitor, wherein the capacitor is inserted by means of its contacts in the socket. The base has a housing and a cover arranged on the upper side of the housing in the form of a cap, wherein a first and a second pocket with a passage opening in the bottom area are formed in the housing. In each of the first and second pockets, an electrically conductive cutting clip can be integrated in such a way that the clip has a clamping region accommodating a contact of the capacitor in the housing and a passage opening extending through the respective first or second through-opening arranged in the bottom region out of the housing Board / circuit board has connectable contact area. The first and second pockets are capped with the cap, the cap having first and second spaced through openings. The passage openings are arranged coaxially to the pockets of the housing to the distance of the contacts of the electrical component to each other accordingly.

The clip or also referred to as NIF contact is preferably formed in the manner of a cutting clip or a clamping clasp. Such clips or cutting clips or clamping clips are sometimes referred to as spring terminals.

The cutting clip or clamping clip is preferably formed in one piece from a flat strip material and can be produced by means of simple forming processes.

The cutting clasp / clamping clasp is designed such that the contact area in the Clamping area passes, wherein the clamping area is divided into a rigid, on a first side wall of the passage opening supporting abutment area and a distance to this investment area elastically resilient end portion. The capacitor contact can be inserted clamped between the contact area and the resilient end area.

The end face of the elastically resilient end region of the cutting clip is designed substantially pointing in the direction of the contact region. In addition, the contact area is slightly angled with respect to the end face and provided with an additional insulation displacement terminal, so that when inserting the capacitor, the cutting edge of the end face and the cutting edge of the contact area have a penetrating and clamping effect on the respective contact. This allows for fixing, secure clamping and connecting the capacitor to a board / circuit board.

The base is cylindrically shaped and has a flattening parallel to the first and second pockets at the edge of the base from the upper side of the housing to the underside of the housing. This serves as a twist protection in the blister strip, as a guide for placement machines and as an orientation aid in the joining of the cutting clip in the housing.

The underside of the housing is flat, so that the housing lies flat on a carrier material in the form of a circuit board or printed circuit board.

In an advantageous embodiment, the first and second pockets are positively connected to the respective cutting claw disposed therein such that the first and second pockets form an inner and outer abutment area for the cutting clasp.

In each case a web is formed on the housing in the first and second pockets, wherein the web is formed on the opposite side of the contact region of the electrical component to the cutting clip. This prevents the displacement of the resilient end portion of the cutting clip.

In an alternative embodiment, the passage openings arranged in the bottom area of the housing each have a lateral recess. Thus, the contact areas of the cutting clips can be guided laterally out of the housing.

The cap preferably has an expression, wherein the expression cooperates with a counterpart in the form of a recess in the housing such that the positive engagement counteracts a slipping of the cap with respect to the housing.

The cap of the base is provided with two through holes, thereby allowing a centered passage of the contacts of the electrical component to the cutting clips.

The cutting clips are arranged in the first and second through-openings in such a way that a positive connection is created between the inner contour of the through-openings and the outer contour of the cutting clips. Through the cap and the positive connection of the bag slipping out of the cutting clip is prevented.

The pedestal can be brought and connected to a circuit board or circuit board by means of surge, selective or reflow soldering from a blister strip with the aid of the contact regions of the respective cutting clip.

Subsequently, the capacitor or other electrical component is plugged into the socket. The manual soldering is eliminated, which leads to a reduction in time in the production and thus to a cost reduction. In addition, this allows easy repair of assemblies.

The invention will be explained in more detail below using an exemplary embodiment and associated drawings.
